Embodiment Construction

[0018] Such as figure 1 Shown is the structural diagram of the test device, including the disc cutting and measuring device (composed of 1-7, 11, 12, 13), walking trolley 10, cutting height adjustment motor 8, central console 9 and stem clamp holding device 15.

[0019] Such as figure 1 , 2 As shown, the disc cutting measuring device includes a blade 1, a cutterhead 2, a spoke disk 13, a cutterhead shaft 12, a bearing seat 3, a coupling A4, a torque speed sensor 5, a coupling B6, a drive motor 7 and Cut standoff 11. The blade 1 is connected to the cutter head 2 by bolts or rivets. There is a hole a on the cutter head 2. The position of the hole a is fixed. There are multiple holes b on the cutter head 2. The position of the hole a on the cutter head is fixed. There are many holes b There are several different locations to choose from during installation. But the center of hole b is all on the circle with the center of hole a as the center, and the distance between the cen...

Abstract

The invention discloses a disc-type stalk cutting test device and a test method thereof. The disc-type stalk cutting test device is mainly used for measuring the cutting force and the cutting energy consumption when a disc with a blade rotatably cuts stalks of various crops. The test device comprises a disc-type cutting measurement device, a walking trolley, a cutting height adjusting motor, a central control platform and a stalk clamping device. The disc-type cutting measurement device is driven by a motor, and has adjustable cutting speed; an output shaft system passes by a torque sensor and then drives a cutter head to rotate so as to cut the stalks to be cut in the stalk clamping device; the cutting torque is obtained by the measurement of the sensor; and the cutting force and the cutting energy consumption can be obtained by calculation; the walking speed of the walking trolley is adjustable; the device has strong generality; the operating method is stable and reliable; and the disc-type stalk cutting test device can be used for indoor simulation or actual field test.

Description

technical field [0001] The invention relates to a test device for cutting crop stalks with a disc cutter and a test method thereof, which can be used for measuring cutting force and cutting energy consumption when cutting stalks indoors or in the field. Background technique [0002] Stem cutting is an important part of crop harvesting. The commonly used cutting methods are mainly reciprocating cutting and disc cutting. These two methods have their own advantages and disadvantages, but no matter which cutting method, the cutting speed, cutting force and cutting Energy consumption is an important basis for designing cutters. At present, the devices for measuring stem cutting force and energy consumption are all reciprocating cutting (such as the patented stem cutting test device and method CN200710192398.3 and the patented stem cutting performance test bench CN200820124630.X), and there is no disc cutting measurement Device reports. The disc cutter is a stem cutting test dev...
