The geared control shaft 206 and control gear 205 in the depth limiting control component 2 make the positioning and control of the control screw 203 simple and convenient, thus making the depth limiting control component 2 highly convenient to control the depth limiting wheel 3. The adapter sleeve 208 makes the installation, positioning and adapter of the depth limiting wheel 3 simple and convenient, and the depth limiting control component 2 can make the depth limiting wheel 3 have a good depth limiting control effect when in use.

[0033] Locking seats 209 are provided at both ends of the power loading box 202 and the gear plate adjustment shaft 206. A reinforcing telescopic sleeve 210 is provided on the lower side of the power loading box 202, corresponding to the adjustment screw 203, with the lower end of the reinforcing telescopic sleeve 210 fixedly connected to the lower end of the adjustment screw 203.

[0034] In this design, the depth limiting device for the reversible stubble destroyer connects to the reversible stubble destroyer's transfer beam via the transfer seat 101 of the transfer assembly 1. The lower positioning roller 110 and upper positioning roller 112 facilitate easy and convenient position adjustment of the transfer assembly 1. After the position of the transfer seat 101 is adjusted, the upper control handle 118 rotates the second control screw shaft 114, which in turn pushes the upper push rod 115 under the action of the second control cylinder 113, causing the upper push rod 115 to contact and position itself against the transfer beam. Then, the side control handle 105 rotates the first control screw shaft 104, causing the first control cylinder 103 to push the side push rod 106, thus achieving the desired depth. The positioning of the adapter 101 is completed; the lower positioning roller 110 on the adapter 101 and the lower positioning roller 112 on the positioning top plate 111 in the adapter assembly 1 make the adapter assembly 1 easy to install; the side top rod 106 and the upper top rod 115 make the pre-positioning of the adapter assembly 1 easy, thus making the overall installation, positioning and use effect of the reverse stubble wiping machine depth limiting device good; the limiting rod can limit the adjacent first control cylinder 103 and second control cylinder 113, making the pushing and positioning stability of the first control cylinder 103 and second control cylinder 113 on the side top rod 106 and the upper top rod 115 high, thus making the adapter assembly 1 have high transfer positioning stability;

[0035] The gear-disc adjustment shaft 206 is adjusted by the hand crank 207, which in turn drives the adjustment gear 205 to rotate the threaded cylinder seat 204, causing the adjustment screw 203 to rise and fall, thus adjusting and positioning the depth limiting wheel 3. The limit lock seat 303 makes the wheel axle 301 of the depth limiting wheel 3 and the adapter sleeve 208 easy to install, use, disassemble, and separate. The gear-disc adjustment shaft 206 and the adjustment gear 205 in the depth limiting adjustment assembly 2 make the positioning and adjustment of the adjustment screw 203 simple and convenient. This makes it easy for the depth limiting control component 2 to control the depth limiting wheel 3. The adapter sleeve 208 makes the installation and positioning of the depth limiting wheel 3 simple and convenient. The depth limiting control component 2 enables the depth limiting wheel 3 to have a good depth limiting control effect during use. The locking seat 209 enables the locking of the gear plate control shaft 206, thereby making the positioning stability of the control screw 203 high. The reinforced telescopic sleeve 210 can reinforce the control screw 203, making the support stability of the control screw 203 higher, thereby improving the depth limiting effect of the depth limiting wheel 3.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
