[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0033] Embodiment 1

[0034] Refer to Figures 1 - 5 , which is the first embodiment of the present invention. This embodiment provides a sugarcane stubble trimming, ridge breaking, fertilizing and film covering combined operation machine. The sugarcane stubble trimming, ridge breaking, fertilizing and film covering combined operation machine includes a main body assembly 100, including a machine body 101. On one side of the machine body 101, there is a support frame 102. The support frame 102 can tilt up and down on one side of the machine body 101, and can drive the rotary cutter 104 and the film covering mechanism 105 to move up and down, so that the two can contact or separate from the ground.

[0035] A fertilizer box 103 is fixed inside the support frame 102. The fertilizer box 103 is used to store fertilizers. Fertilizing mechanisms are provided on both sides of the bottom. During the operation by the user, fertilizers are applied to the field. A rotary cutter 104 and a film covering mechanism 105 are provided at the bottom of the support frame 102. During the movement, the ground can be stubble trimmed and ridge broken by the rotary cutter 104, and the ground can be covered with film by the film covering mechanism 105. Through the cooperation of the above components, the operations of stubble trimming, ridge breaking, fertilizing, film covering and soil hilling can be completed. This is the prior art and will not be elaborated much in this solution. And those skilled in the art can clearly understand the working principle.

[0036] The auxiliary component 200 is arranged at the bottom of the support frame 102 and includes a cutting piece 201. The cutting piece 201 includes a support frame 201a fixed to the bottom of the support frame 102. The support frame 201a is fixed to the bottom of the support frame 102 through a connecting column. A movable rod 201b is inserted into the support frame 201a, and the movable rod 201b is movably connected inside the support frame 201a. A support column 201c is fixed to the bottom of the movable rod 201b. A pressing plate 201d is movably connected to the outside of the support column 201c. The support column 201c is used to support and position the pressing plate 201d. The above structures are both two and are respectively located on both sides of the bottom of the support frame 102.

[0037] A cutting block 201e is arranged below the pressing plate 201d. When covering the film, both the pressing plate 201d and the cutting block 201e are at a high position and will not contact the ground film. When the film covering is completed, the pressing plate 201d drives the cutting block 201e to move downwards, so that the cutting block 201e can contact the ground film. At this time, the cutting block 201e will move horizontally at the bottom of the pressing plate 201d and cut off the ground film. In this way, there is no need for the operating equipment to stop and wait, thereby improving the operating efficiency, and the cut gap of the ground film is neat. Furthermore, the starting position and the ending position of the ground film covering can ensure the heat preservation and moisture preservation of the ground film.

[0038] The auxiliary component 200 further includes a positioning piece 202. There are two groups of positioning pieces 202, which are respectively located on both sides of the bottom of the support column 201c. The positioning piece 202 includes a positioning plate 202a at the bottom end of the support column 201c. A positioning frame 202b is movably connected to the outside of the positioning plate 202a. The positioning frame 202b is movably connected to the outside of the positioning plate 202a. A plurality of friction strips are fixed to the top of the positioning frame 202b, which can ensure the stability of the fixation of the ground film when the positioning frame 202b and the pressing plate 201d clamp the ground film.

[0039] A connecting rod 202c is arranged on the top of the positioning frame 202b. The top and bottom ends of the connecting rod 202c are respectively hinged to the positioning frame 202b and the pressing plate 201d through hinge plates. The number of the connecting rods 202c can be set according to actual needs to ensure the stability of the movement of the positioning frame 202b.

[0040] When covering the film, the positioning frame 202b and the positioning plate 202a are always located below the ground film, and the positioning frame 202b is completely sleeved outside the positioning plate 202a and will not contact the ground film. When the pressing plate 201d moves downwards, it will drive the positioning frame 202b to move through the connecting rod 202c, so that the positioning frame 202b moves below the ground film and can contact the bottom of the ground film. At this time, the ground film can be clamped and fixed through the cooperation of the pressing plate 201d and the positioning frame 202b, thereby avoiding the situation that the ground film drifts after being cut, which is not convenient for pressing and fixing the ground film.

[0041] When starting to cover the film, the pressing plate 201d drives the positioning frame 202b to move downward, making the positioning frame 202b in close contact with the ground and unable to move. At this time, when the machine body 101 moves, the starting position of the plastic film can be fixed through the cooperation of the pressing plate 201d and the positioning frame 202b. When the machine body 101 moves, the movable rod 201b will move outward from the support frame 201a, so that the pressing plate 201d and the positioning frame 202b can always be in this position and fix the plastic film. During the fixing process, the accuracy of the plastic film position can be ensured, and the plastic film will not shift. When the machine body 101 moves a certain distance and the starting position of the plastic film has been compacted and covered by the soil, the pressing plate 201d and the positioning frame 202b move upward and separate from the plastic film. At the same time, the movable rod 201b will move into the support frame 201a and move to the initial position, and the pressing plate 201d and the positioning frame 202b are reset respectively.

[0042] Embodiment 2

[0043] Referring to Figures 5 - 10 , this is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, a support block 201f is fixed at the bottom of the pressing plate 201d. A reciprocating roller 201g is rotatably connected inside the support block 201f, and a fixed shaft 201h is fixed inside the cutting block 201e.

[0045] When the pressing plate 201d drives the cutting block 201e to contact the plastic film, the reciprocating roller 201g will rotate, and drive the cutting block 201e to move through the cooperation of the fixed shaft 201h, so that the cutting block 201e can cut the plastic film. When the cutting block 201e moves to the end of the reciprocating roller 201g, it will stop moving, and at this time, one cutting is completed.

[0046] When the pressing plate 201d drives the cutting block 201e to contact the plastic film, the reciprocating roller 201g will rotate again. At this time, the cutting block 201e will move in the reverse direction and can cut the plastic film again.

[0047] Specifically, a positioning rod 202d is fixed at the top of the positioning plate 202a. The positioning plate 202a is connected to the support column 201c through the positioning rod 202d, and the positioning plate 202a can move downward. A slot 201c-1 is opened on the support column 201c. The top end of the positioning rod 202d is inserted into the slot 201c-1. A first spring 202e is fixed at the top end of the positioning rod 202d, and the top end of the first spring 202e is fixed to the inner wall of the slot 201c-1. By applying an upward pulling force to the positioning rod 202d through the first spring 202e, when the pressing plate 201d releases the pressing on the positioning plate 202a, the positioning rod 202d and the positioning plate 202a can be driven to reset by the first spring 202e.

[0048] Specifically, the auxiliary component 200 further includes a rotating member 203. The rotating member 203 includes a mounting box 203a fixed to one side of the support block 201f. A torsion spring 203b is arranged in the mounting box 203a. The mounting box 203a is used for mounting the torsion spring 203b. One side of the support block 201f is rotatably connected to a rotating sleeve 203c. The rotating sleeve 203c is fixed to the inner side of the torsion spring 203b.

[0049] Specifically, a fixed frame 203d is fixed to the inner side of the rotating sleeve 203c. A clamping block 203e is arranged in the fixed frame 203d. One side of the clamping block 203e is inclined. A clamping groove 201g-1 is formed in the reciprocating roller 201g. The clamping block 203e is engaged with the clamping groove 201g-1. The number of the clamping grooves 201g-1 is multiple and they are annularly and evenly distributed on the outer side of the reciprocating roller 201g. Through the cooperation of the clamping block 203e and the clamping groove 201g-1, the rotating sleeve 203c is connected to the reciprocating roller 201g, so that the rotating sleeve 203c can drive the reciprocating roller 201g to rotate unidirectionally.

[0050] A second spring 203f is fixed to the top of the clamping block 203e. The second spring 203f is used to apply a thrust to the clamping block 203e to make the engagement between the clamping block 203e and the clamping groove 201g-1 tighter.

[0051] Specifically, a gear 203g is rotatably connected to one side of the mounting box 203a. The gear 203g is rotatably connected to one side of the mounting box 203a through a bearing. A rack 203h is arranged on one side of the gear 203g. The rack 203h is fixed to the support column 201c through an L-shaped fixing rod. The gear 203g is engaged with the rack 203h.

[0052] The gear 203g is sleeved on the outer side of the rotating sleeve 203c and is connected to the rotating sleeve 203c in a ratchet and pawl manner. Through the cooperation of the ratchet and pawl, the gear 203g can drive the rotating sleeve 203c to rotate only when the gear 203g moves upward and rotates through the cooperation of the rack 203h. When the gear 203g moves downward and rotates, it will not drive the rotating sleeve 203c to rotate. And when the pressing plate 201d moves to the lowest position, the gear 203g and the rack 203h are in a separated state, so as not to affect the self-rotation of the gear 203g.

[0053] When the pressure plate 201d is at a high position, the coil spring 203b is in a tightened state. When the pressure plate 201d drives the cutting block 201e downward to contact the ground film, at this time, the torsional force of the coil spring 203b drives the rotating sleeve 203c to rotate. The rotating sleeve 203c drives the reciprocating roller 201g to rotate through the cooperation of the clamping block 203e and the card slot 201g-1. In this way, the reciprocating roller 201g can drive the cutting block 201e to move. And when the elastic force of the coil spring 203b is completely released, the cutting block 201e just moves to the end of the reciprocating roller 201g.

[0054] When the pressure plate 201d moves upward, the gear 203g meshes with the rack 203h and drives the rotating sleeve 203c to rotate when rotating. At this time, the rotating sleeve 203c tightens and energizes the coil spring 203b. And when the rotating sleeve 203c rotates, it will not make the reciprocating roller 201g rotate, thus avoiding the situation that the cutting block 201e moves in the reverse direction and scratches the covered ground film. When the pressure plate 201d returns to its original position upward, the coil spring 203b can be in a tightened state again.

[0055] Embodiment 3

[0056] Refer to Figures 1 - 11 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0057] Specifically, the auxiliary component 200 further includes a limiting member 204. The limiting member 204 includes a limiting post 204a. The reciprocating roller 201g is provided with a plurality of limiting holes 201g-2, which are annularly and evenly distributed on the outer side of the reciprocating roller 201g. The limiting post 204a is inserted into the limiting hole 201g-2. Through the cooperation of the limiting post 204a and the limiting hole 201g-2, it is used to limit the reciprocating roller 201g to prevent the rotating sleeve 203c from causing the reciprocating roller 201g to rotate when tightening the coil spring 203b, thereby causing the position of the cutting block 201e to move.

[0058] A force-receiving rod 204b is fixed on one side of the limiting post 204a. The force-receiving rod 204b is L-shaped, and one end extends downward. When the pressure plate 201d is about to contact the positioning frame 202b, the bottom end of the force-receiving rod 204b will contact the positioning plate 202a first and be driven by the reverse thrust of the positioning plate 202a to drive the limiting post 204a to move upward, so that the limiting post 204a is separated from the limiting hole 201g-2, thereby releasing the restriction on the reciprocating roller 201g and enabling the reciprocating roller 201g to rotate.

[0059] Specifically, stabilizing columns 204c are fixed to the bottom of the pressing plate 201d. There are two stabilizing columns 204c, which are respectively fixed to both sides of the bottom of the pressing plate 201d. The stabilizing columns 204c are movably connected to the inside of the stress rod 204b for supporting and positioning the stress rod 204b. A third spring 204d is fixed to the top of the stress rod 204b, and the top end of the third spring 204d is fixed to the pressing plate 201d. The third spring 204d is used to apply a pulling force to the stress rod 204b. When the bottom end of the stress rod 204b is separated from the positioning plate 202a, the limiting column 204a can be driven to engage with the limiting hole 201g-2 again.

[0060] Specifically, an installation frame 205 is fixed to one side of the movable rod 201b, and an electric push rod 206 is fixed to the installation frame 205. The output end of the electric push rod 206 is fixed to the pressing plate 201d.

[0061] The installation frame 205 is used to support and fix the electric push rod 206 and can move along with the movable rod 201b. Through the setting of the electric push rod 206, it is used to drive the pressing plate 201d to move up and down.

[0062] Specifically, a fourth spring 201i is fixed to one end of the movable rod 201b, and the other end of the fourth spring 201i is fixed to the inner wall of the support frame 201a.

[0063] When the end of the plastic film is fixed and the pressing plate 201d and the positioning frame 202b move upward, at this time, the fourth spring 201i can be used to pull the movable rod 201b to move, so that the movable rod 201b is reset into the support frame 201a. At the same time, the electric push rod 206 is used to drive the pressing plate 201d to move upward.

[0064] During use, after the film covering is completed, the electric push rod 206 is used to drive the pressing plate 201d to move downward, and the pressing plate 201d drives the cutting block 201e to move downward, so that the cutting block 201e can contact the plastic film. At the same time, the torsion force of the coil spring 203b is used to drive the rotating sleeve 203c to rotate. The rotating sleeve 203c drives the reciprocating roller 201g to rotate through the cooperation of the clamping block 203e and the clamping groove 201g-1. In this way, the reciprocating roller 201g can drive the cutting block 201e to move, so that the cutting block 201e moves horizontally at the bottom of the pressing plate 201d and cuts the plastic film. In this way, there is no need for the operating equipment to stop and wait, which can improve the operating efficiency, and the cut of the plastic film is neat. Furthermore, the heat preservation and moisture preservation properties of the plastic film can be ensured at both the starting position and the ending position of the plastic film covering.

[0065] When the pressing plate 201d moves downward, it will drive the positioning frame 202b to move through the connecting rod 202c, so that the positioning frame 202b moves under the plastic film and can contact the bottom of the plastic film. At this time, the plastic film can be clamped and fixed through the cooperation of the pressing plate 201d and the positioning frame 202b. When starting to cover the film, the electric push rod 206 drives the pressing plate 201d to move downward again, and the pressing plate 201d drives the positioning frame 202b to move downward, so that the positioning frame 202b is in close contact with the ground and cannot move. At this time, when the machine body 101 moves, the starting position of the plastic film can be fixed through the cooperation of the pressing plate 201d and the positioning frame 202b. At this time, when the machine body 101 moves, the movable rod 201b will move outward to the outside of the support frame 201a, and then the pressing plate 201d and the positioning frame 202b can always be in this position and fix the plastic film. And during the fixing process, the accuracy of the position of the plastic film can be ensured, so that the plastic film will not be offset.

[0066] When the machine body 101 moves a certain distance and the starting position of the plastic film has been compacted and covered by the soil, the electric push rod 206 drives the pressing plate 201d and the positioning frame 202b to move upward, so that the two are separated from the plastic film. At the same time, the movable rod 201b will move into the support frame 201a and move to the initial position, and the pressing plate 201d and the positioning frame 202b are respectively reset.

[0067] When the pressing plate 201d moves upward, the gear 203g meshes with the rack 203h, and when rotating, it will drive the rotating sleeve 203c to rotate. At this time, the rotating sleeve 203c will tighten and charge the coil spring 203b. And when the rotating sleeve 203c rotates, it will not make the reciprocating roller 201g rotate, thereby avoiding the situation that the cutting block 201e moves in the reverse direction and scratches the covered plastic film. When the pressing plate 201d is reset upward, the coil spring 203b can be in a tightened state again.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
