Problems solved by technology

However, in actual use, the hand frame of the digging machine used for planting seedlings used by farmers and nursery staff is directly connected to the frame body. Because of the complex situation of the soil, it will inevitably cause vibrations, especially when digging pits. When encountering stones and other situations during the process, the instantaneous vibration received by the drill bit is directly transmitted to the user, causing injury to the construction personnel. Therefore, the existing digging machine for seedling planting has potential safety hazards, and a shock-absorbing device is needed 4

Embodiment 1

[0025] Such as figure 1 As shown, a kind of digging machine for nursery stock planting comprises a gasoline engine 1, a reduction device 2, and a drill bit 3. The gasoline engine 1 and the reduction device 2 are fixed by bolt locking, and the output shaft of the reduction device 2 is connected with the drill bit 3 to drive the drill bit. 3. It also includes the damping device 4 of the digging machine for planting seedlings, and the damping base 41 of the damping device 4 of the digging machine for planting seedlings is fixedly installed on the speed reduction device 2 . Shock absorbing device 4 comprises a shock absorbing base 41 and hand-held frame 42, and described base is fixed with left and right fork frame 43, and the front end left end of described hand-held frame 42 is hinged with left connecting rod, and described hand-held frame 42 The right end of the front end of the front end is hinged with a right connecting rod 44, and the left connecting rod is hinged with the l...

Embodiment 2

[0028] On the basis of the first embodiment, there are two shock absorbers 46, and the axes of the two shock absorbers 46 are parallel to each other.

[0029] The axes of the shock absorbers 46 are parallel to each other to avoid damage to the shock absorbers 46 when vibrating. When the construction personnel use the digging machine for planting seedlings to dig the pit, the drill bit 3 starts to drill, and the digging machine digs the pit downward. Seedling planting is deviated with the direction of the drill bit of the digging machine, and then the body of the digging machine is vibrated, and when the vibration is transmitted to the shock-absorbing base 41, the seedling planting is used for the digging machine shock absorber 4 to start acting. If the axes of the shock absorber 46 are not parallel, so that the working strokes of the shock absorber 46 are different, the force of the shock absorber 46 and the shock absorbing spring 47 will be uneven, and the shock absorber 46 a...

Embodiment 3

[0031] On the basis of the second embodiment, the drill bit 3 is detachably fixed on the output shaft of the reduction gear 2 through the cylindrical pin 35 slot and the cylindrical pin 35.

[0032] Because the nursery workers need to dig holes with different diameters and depths for the trees and flowers to be planted during construction, and the soil conditions they face are different during the digging operation. Change the drill bit 3 of different materials, or when digging a hole, because of the design of the greening personnel, the required difference of the same piece of land also has different diameters and depths. At this time, because the drill bit 3 is inserted through a cylindrical pin Groove and straight pin 35 are detachably fixed on the output shaft, after the straight pin 35 is taken out from the straight pin slot, the drill bit 3 can be disassembled from the output shaft, and then the required drill bit can be changed.

[0033] During the transport process of th...

Abstract

The invention discloses a damping device for a hole-digging machine for nursery stock planting and a hole-digging machine, belongs to earth drilling equipment and aims to effectively reduce the vibration of a handrail frame of the hole-digging machine for nursery stock planting. The hole-digging machine comprises a gasoline engine, a speed reducer, a drill bit and the damping device for the hole-digging machine for nursery stock planting, wherein the damping device for the hole-digging machine for nursery stock planting comprises a handrail frame and a damping base; a left fork rack and a right fork rack are fixed on the damping base; four connecting rods are hinged between the left fork rack and the handrail frame as well as between the right fork rack and the handrail frame; a damper ishinged between the damping base and a cross beam of the handrail frame; a damping spring is sleeved on the damper. The damping device is capable of effectively reducing the vibration of the handrail frame of the hole-digging machine for nursery stock planting in the working process and the nursery operator can conveniently dig holes.

Description

technical field [0001] The invention belongs to land drilling equipment, and in particular relates to a digging machine for seedling planting and a shock absorbing device thereof. Background technique [0002] The digging machine plays a very important role in the production activities of the nursery. The digging machine in our country originated in the 1960s and 1970s, and then gradually became popular, especially in nursery planting. In recent years, portable and suspended digging machines have gradually appeared, especially after entering the 21st century, hydraulic power-controlled digging machines have not only high power, strong mobility, but also large digging specifications, which are popular in my country. Widespread attention and welcome. And this digging machine is mainly used in large-area operations, simple to operate, easy to use, and widely promoted. However, in actual use, the hand frame of the digging machine used for planting seedlings used by farmers and...
