A cutting tooth having a blade-like cutting section and a mounting section extending down from the bottom of the cutting section. The mounting section is narrower and shorter than the cutting section, and generally centered with respect to the cutting section. The mounting section has laterally extending flanges spaced from the cutting section. At least a quarter of the cutting section extends past the front of the mounting section and terminating in a cutting edge.The cutting tooth is adapted to be mounted in a mounting block to form a cutting assembly. The mounting block has a slot extending into the block from the front face, the slot open in the top surface of the block. The mounting section of the tooth slides into the slot in the block to locate the cutting section on the top of the block with the cutting section projecting forwardly of the block. The flanges on the tooth hold the tooth in place in the block against centrifugal forces. The cutting assembly is adapted to be mounted between two collars on a brush cutting drum with the cutting tooth above the periphery of the collars.

The invention provides a casting mold and forming method for a box body of a gearbox and belongs to the technical field of liquid formation of metal. The forming method comprises the following steps that precoated sand is used for core shooting, so that precoated sand blocks are manufactured, then an outer precoated sand mold layer is formed by splicing the precoated sand blocks, and the outer precoated sand mold layer and a sand core are used for forming a casting cavity of the box body of the gearbox; and finally the box body of the gearbox is manufactured through the casting mold in a low-pressure casting way. According to the specific structure of the casting mold, the sand core is located in the center of the casting mold; the casting cavity is formed in the outer layer of the sand core and mainly formed by the sand core and the outer precoated sand mold layer; an outer resin sand mold layer is arranged on the outer layer of the outer precoated sand mold layer, and the outer precoated sand mold layer and a sand box are connected through the outer resin sand mold layer, so that the casting mold is formed. According to the casting mold and forming method for the box body of the gearbox, the cavity which is formed by the precoated sand and used for large complicated castings is used for low-pressure casting for the first time, the precoated sand blocks are subjected to core shooting under pressure, high-temperature sintering formation is conducted, filling is compact, and the situations that sand filling is incompact and sand adhesion defects are caused due to human factors during resin sand molding are avoided.

The embodiment of the invention provides a disk writing method for disk arrays and a disk writing device for the disk arrays. The method includes: acquiring a sequence, according to physical addresses of logic units, of the logic units in the same RAID (redundant array of independent disks) group of disk arrays; and writing the disk writing concurrence IOs (inputs / outputs) of the RAID groups to the logic units of the RAID groups according to the sequence of the physical addresses of the logic units, wherein each writing concurrence IO includes at least one dirty page of one logic unit to be written into the RAID group. The disk writing method for the disk arrays and the disk writing device for the disk arrays reduce the time which is consumed when a magnetic arm jitters back and forth in addressing through uniform scheduling of the logic units in a single RAID group and then writing the disks according to the sequence of the physical addresses and avoid the effects among different RAID groups through control of the RAID groups so that writing efficiency of the disk arrays is improved and throughput capacity of the disk arrays is increased.

The inventionrelates to the technical field of white spirit processing and in particular relates to a lime watersmearing device for outer walls of a wine jars. The device comprises a conveying device, a lime water brushing device, a water tank and a drying device, wherein rolling wheels are arranged on theconveying device andare divided into a front group of rolling wheelsand a rear group of rolling wheels; a track is arranged onthe front group of rolling wheels; a certain distance is reserved between the front and rear groups of rolling wheelsand is slightly largerthan themaximum diameter of wine jarsto be washed; the conveying device is used for conveying the wine jars; the lime water brushing device is positioned between the front and rear groups of rolling wheelsand is used for uniformly coating the outer walls of the wine jars with lime water; the water tank is positioned right below the lime water brushing device and is filled withthe lime water; the drying device is positioned above the rear group of rolling wheels and is used for stoving the outer walls of the wine jars. By using the device, the processes of automatically coatingthe outer wall of the wine jars with the lime water andautomatically stoving the outer walls of the wine jars can be realized; the damage of the wine jars can be detected so thatthe damaged wine jars can be treated in real time, so that the loss is reduced.

The invention discloses a device for automatic painting of indoor walls, comprising a strip-shaped bearing base, the upper surface of the strip-shaped bearing base is fixedly connected with a mixing box, and the upper surface of the strip-shaped bearing base is A No. 1 N-shaped support frame is arranged across the mixing box, an automatic painting mechanism is provided at the center of the upper surface of the No. 1 N-shaped support frame, and a moving mechanism is provided on the lower surface of the strip-shaped bearing base. The mixing box The lower surface of the body is provided with a lifting and cleaning mechanism. The beneficial effects of the present invention are that the operation is relatively convenient, the labor intensity of the workers is reduced, the boundaries are marked accurately, the brushing efficiency is high, it is easy to move, the brushing is uniform, the bucket carrying the paint is easy to clean, and the manual contact is reduced. The irritating smell that comes, the device that guarantees the health of employees.

The invention discloses that the invention belongs to the technical field of construction machinery, in particular a high-efficiency painting device for the outer wall of a large building. Most of the existing building walls are painted manually, which is time-consuming and dangerous, so the efficiency is relatively slow, and Most of these interior decoration materials contain harmful substances, and long-term exposure is not conducive to human health and other shortcomings. The following proposal is now proposed. A high-efficiency painting device for the outer wall of a large building includes a base, and the upper part of the base is welded with a first column and a second Column, the first column and the second column are on the same straight line, and the length of the two is equal, the second column is in the shape of "mouth", the top of the first column and the second column are welded on the top plate, and the upper part of the top plate is fixed by the bracket There are servo motors and paint storage tanks. The high-efficiency painting device for the outer wall of a large building is convenient to use, has high painting efficiency, is beneficial to the health of workers, and is easy to be widely popularized.

An automatic spraying production line for a titanium alloy thermal forming protective coating is characterized by specifically comprising seven functional modules including a control system, an annular assembly line, two spraying chambers, a coating supply system, a workpiece feeding / discharging and overturning combined station, a hot air drying system and an exhaust system. A spraying technology of the automatic spraying production line for the titanium alloy thermal forming protective coating comprises the steps that a PLC is matched with a travel switch, a photoelectric proximity switch and a distance sensor, the strokes and positions of a workpiece and a mechanical part are detected, a technological process diagram is compiled, control logic is set, and a ladder diagram is drawn on the basis; on the basis, coordination control is carried out on all subsystems through the preset program, and automation of the technological process is achieved.
