[0002] An important part of the field management of tall crops such as corn, sorghum, and cotton is topping the plants, pinching off the top of the crops to eliminate the top growth advantage, promote the development of crop lateral branches and fruits, and control lodging, which is of great significance to improving crop quality and yield. Traditional crop topping is done manually, which is labor-intensive and inefficient. Chinese patent application 2024101138578 discloses "A folding and lifting high-stalk crop topping machine and use method", including a frame assembly, a reel assembly, a cutting assembly, a lifting frame assembly and a hydraulic drive assembly, wherein the drive assembly adopts a hydraulic drive and the cutting assembly adopts a reciprocating shearing cutter head, which has a complex structure, a high failure rate, and poor fault tolerance. When encountering branches that cannot be cut, it is easy to get stuck and uproot the entire plant, causing losses. My other Chinese patent application 2024214724775 provides "A crop topping machine", the application date is June 26, 2024, the crop topping machine includes a transmission box, a bracket fixedly mounted on the transmission box, a transmission shaft rotatably mounted on the bracket, a gear box is installed on the transmission shaft, the gear box includes a gear box housing, a driving bevel gear rotatably mounted on the side wall plate of the gear box housing through a bearing, and a driven bevel gear rotatably mounted on the bottom plate of the gear box housing through a bearing, the driven bevel gear is constantly meshed with the driving bevel gear, the transmission shaft is inserted through the gear box housing, and is connected to the driving bevel gear; the driven bevel gear is fixedly connected to the output shaft, the output shaft passes through the bottom plate of the gear box housing, and a cutter is installed at the lower end of the output shaft. This crop topping machine can flexibly adjust the spacing of the cutter heads, and fix the position of the cutter heads by a top screw installed on the wall of the casing. However, after the top screw is tightened, the contact area with the beam is small, the holding force is limited, and it is easy to form dents or deformation on the surface of the beam, affecting the normal sliding of the slide.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions away from the geometric center of a specific component.

[0021] like Figure 1 , Figure 2 As shown, the adjustment mechanism of the crop topping machine described in the utility model includes a slide slidably mounted on the crossbeam 1 of the topping machine frame, and a locking mechanism arranged between the slide and the crossbeam 1. The slide can slide on the crossbeam 1 and the position of the slide can be locked by the locking mechanism.

[0022] like Figure 2 As shown, the slide comprises an upper slide 2, a lower clasp 3 hinged on one side of the upper slide 2, and an end plate 4 fixedly connected to the end of the upper slide 2. The upper slide 2 and the lower clasp 3 are groove structures arranged opposite to each other, and the inner cavity of the groove structure is adapted to the outer contour of the crossbeam 1. So that the crossbeam 1 can pass through the cavity formed by the upper slide 2 and the lower clasp 3 and the slide can move along the axis of the crossbeam 1. The lower end of the end plate 4 is fixedly connected to a mounting plate 6, and the lower end of the mounting plate 6 is connected to a topping cutter head 8 through a transmission gear box 7.

[0023] When in use, the crop topping machine is connected to the rear end of the tractor through a suspension mechanism, and the rear power output shaft of the tractor is connected to the transmission gear box 7 through a coupling and a transmission mechanism to drive the topping cutter head 8 to rotate.

[0024] In this embodiment, the crossbeam 1 is a cylindrical structure or a circular tubular structure with a circular outer contour, the upper slide plate 2 is a semicircular arc groove with the notch facing downward, and the lower buckle plate 3 is a semicircular arc groove with the notch facing upward. When the upper slide plate 2 and the lower buckle plate 3 are buckled together, their inner cavity forms a cylindrical structure that matches the outer contour of the crossbeam 1. As another embodiment of the utility model, the crossbeam 1 can also be a rectangular columnar structure or a square tubular structure with a rectangular outer contour. In this case, the upper slide plate 2 is a rectangular groove with the notch facing downward, and the lower buckle plate 3 is a rectangular groove with the notch facing upward. When the upper slide plate 2 and the lower buckle plate 3 are buckled together, their inner cavity forms a rectangular columnar structure that matches the outer contour of the crossbeam 1.

[0025] In addition, the crossbeam 1 includes two crossbeam rods parallel to each other, and the slide includes a groove structure composed of two sets of upper slide plates 2 and lower buckle plates 3. The two crossbeam rods and the connecting plates at their ends together form a stable rectangular frame structure, and the slide is supported by the two crossbeam rods, which is conducive to maintaining stability.

[0026] like Figure 2 As shown, the upper slide plate 2 and the lower clasp plate 3 have folded edges extending outward on the opposite sides, the upper slide plate 2 is provided with a bolt receiving hole on the folded edge, and the lower clasp plate 3 is provided with a bolt mounting hole on the folded edge, and the bolt mounting hole is threadedly connected with a fastening bolt 5, and the bolt receiving hole is a light hole whose inner diameter is adapted to the fastening bolt 5. The fastening bolt 5 passes through the bolt receiving hole and is connected to the bolt mounting hole. The slide can slide on the beam 1 by loosening the fastening bolt 5, and the lower clasp plate 3 can be tightened by tightening the fastening bolt 5, and the upper slide plate 2 and the lower clasp plate are used to hold the beam 1 tightly, so as to fix the position of the slide. After locking the lower clasp plate 3, the inner walls of the upper slide plate 2 and the lower clasp plate 3 are in contact with the outer wall of the beam rod of the beam 1, with a large contact area and large friction resistance, which can prevent the beam rod from being sunken due to a small local force area and cause little damage to the beam.

[0027] In addition, a friction plate 9 is provided on the inner wall of the lower buckle plate 3. When the upper slide plate 2 and the lower buckle plate 3 are buckled together, the friction plate 9 is closely attached to the crossbeam 1, the fit is more closely, the friction force is greater, and the stability is better.
