Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a diversion-type integrated residual film land preparation machine. Background Technology

[0002] After crop harvest, the first step is to remove and collect the waste plastic film from the field for disposal. When tilling the land after removing the film, a small amount of film residue may remain on the surface. If this residue is turned into the soil, it will pollute the soil and affect the cultivation of the crop.

[0003] Emergence. In Xinjiang, Northwest China, most crops are planted using a dry-sowing and wet-emergence method, and the land needs to be plowed and prepared after harvest.

[0004] Referring to the authorized patent application CN210900249U, the land leveling machine frame includes: a middle frame, wing frames disposed on both sides of the middle frame, a transport frame disposed at the bottom of the middle frame, and folding cylinders; wherein, the wing frames are connected to the middle frame by folding pins, and there are multiple folding cylinders, divided into two groups disposed on both sides of the middle frame, each folding cylinder having one end connected to the middle frame and the other end connected to the wing frame, and the wing frames can rotate relative to the middle frame about the folding pin as the center through the folding cylinders; wherein, the width ratio of the wing frames to the middle frame is 1.5:1-3:1, and this land leveling machine frame makes transporting the land leveling machine safer and more convenient.

[0005] As shown in the prior art, existing land leveling machines with a large footprint usually have foldable frames, which facilitates the transportation and use of the land leveling machine. However, when the folding frames on both sides of the land leveling machine are folded upwards to maintain the folded state, the folding frames are usually pulled by cylinders to maintain the stability of the folding. However, relying solely on cylinders for stability provides only one layer of stability and lacks overall stability.

[0006] Therefore, it is necessary to provide a land preparation machine to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a diversion-type residual film integrated land preparation machine.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a diversion-type residual film integrated land preparation machine, including a machine body, with movable wheels installed on both sides of the machine body, and folding frames rotatably connected to both sides of the machine body via axle pins, and hydraulic cylinders symmetrically rotatably connected to the top of the machine body, with the extended end of the hydraulic cylinder rotatably connected to the top of the folding frame near it, and a traction frame fixed to the front end of the machine body; hook assemblies and compaction disc assemblies are sequentially installed below the two folding frames and at the end near the traction frame on the bottom of the machine body.

[0009] The upper part of the machine body is symmetrically fixed with mounting blocks near the traction frame. The mounting blocks are equipped with locking components for locking the folded state of the folding frame. The two locking components are equipped with a synchronization structure that enables the two locking components to lock the two folding frames synchronously.

[0010] The body and the folding frame are symmetrically fixed with triangular scrapers at the lower end of the side away from the traction frame.

[0012] Preferably, the synchronization structure is a connecting rod that connects the two side blocks, and the connecting rod is located at the end of the two blocks near the traction frame.

[0013] Preferably, the rolling disc assembly includes three first supports fixed below the machine body and two folding frames, and a plurality of toothed discs are rotatably connected at equal intervals on the first supports. The hook assembly includes a row of hooks respectively mounted below the machine body and two folding frames via rotating shafts, and the hooks are spaced apart from the toothed discs.

[0014] Preferably, the machine body is also equipped with electric actuators that drive corresponding rotating shafts to adjust the distance between the hook blade and the ground.

[0015] Preferably, a rectangular frame is provided on the front side of several toothed discs on the body and folding frame, and a connecting plate is hinged to the middle of both ends of the rectangular frame, with the upper end of the connecting plate fixed to the bottom of the corresponding body and folding frame.

[0016] The rotating shaft that is fixedly installed with several hooks is fixedly connected to the front side of the hinge point of the rectangular frame. A comb plate is provided above several hooks on the rotating shaft. The comb plate is provided with comb grooves that correspond to the upper and lower positions of the hooks and match the width of the hooks.

[0017] A receiving box is set between the hook knife and the toothed disc. The hook knife protrudes downward to the bottom of the receiving box. The front side of the receiving box is open. A hinge plate is fixed in the middle of both ends of the receiving box. The upper part of the hinge plate is hinged to the rear side of the hinge point of the rectangular frame. The tail end of the electric push rod is hinged to the corresponding machine body and folding frame, and the telescopic end is hinged to the middle of the front end of the corresponding rectangular frame.

[0018] The electric actuator is also used to drive the front end of the rectangular frame to rotate upward around the hinge point, causing the hook knife to pass upward through the comb tooth groove of the comb plate, causing the collection box to rotate downward and move forward to the bottom of the comb plate, so that the waste film collected on the hook knife falls into the collection box through the comb plate while the land preparation machine moves forward.

[0019] Preferably, the front end of the bottom plate of the receiving box is bent upwards at 15-25°.

[0020] This utility model provides a land preparation machine. Compared with the prior art, it has the following advantages:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0034] Figures 1 to 3 The first embodiment is shown: a land preparation machine, including a body 1, with movable wheels 2 installed on both sides of the middle part of the body 1, and folding frames 3 rotatably connected to both sides of the body 1 by axle pins. Hydraulic cylinders 4 are symmetrically rotatably connected to the top of the body 1, and the extended end of the hydraulic cylinder 4 is rotatably connected to the top of the folding frame 3 near it. A traction frame 5 is fixed to the front end of the body 1. Hook assemblies and compaction disc assemblies are sequentially installed below the two folding frames 3 and below the body 1 at the end near the traction frame 5.

[0035] Mounting blocks 6 are symmetrically fixed at one end of the upper part of the body 1 near the traction frame 5. Mounting blocks 6 are equipped with locking components that lock the folded state of the folding frame 3. The two locking components are equipped with a synchronization structure that enables the two locking components to lock the two folding frames 3 synchronously.

[0036] Two downward-protruding triangular scrapers 7 are symmetrically fixed below the end of the body 1 and the folding frame 3 away from the traction frame 5. The tip of the first triangular scraper 7 faces backward, and the tip of the second triangular scraper 7 faces forward.

[0037] The locking assembly includes a slot 8 formed on the side of the folding frame 3 near the mounting block 6, a locking block 9 slidably connected to the inner wall of the mounting block 6, the locking block 9 being movably connected to the slot 8, a fixing block 10 fixed to the top of the locking block 9, an elastic piece 11 fixed to the side of the fixing block 10 near the mounting block 6, and the side of the elastic piece 11 away from the fixing block 10 being fixed to the mounting block 6.

[0038] The synchronization structure is a connecting rod 12 that connects the two side blocks 9. The connecting rod 12 is located at the end of the two blocks 9 near the traction frame 5.

[0039] This application locks the folded state of the folding frame 3 by installing a locking component on the mounting block 6, so that the locking block 9 can be locked into the locking slot 8. This adds a stabilizing structure to the hydraulic cylinder 4 that stabilizes the folding state of the folding frame 3, improving the stability of the folding frame 3 when folding. By setting a synchronization structure, the ease of operation is improved.

[0040] The rolling disc assembly includes three first supports 13 fixed below the machine body 1 and two folding frames 3. Several toothed discs 14 are rotatably connected to the first supports 13 at equal intervals. The hook assembly includes three second supports 15 fixed below the machine body 1 and two folding frames 3. A rotating shaft 16 is fixedly connected between the second supports 15. Several hooks 17 are fixed at equal intervals on the outer wall of the rotating shaft 16. The hooks 17 are spaced apart from the toothed discs 14.

[0041] A connecting plate 18 is fixed to the side of the rotating shaft 16 near the toothed disc 14. Electric push rods 19 are rotatably connected to the ends of the machine body 1 and the two folding frames 3 near the traction frame 5. The protruding ends of the three electric push rods 19 are rotatably connected to the three connecting plates 18 respectively. The rotating shaft 16 is rotated by extending and retracting the electric push rods 19 to adjust the distance between the hook blade 17 and the ground.

[0042] This application, by setting an electric push rod 19, makes it easy to adjust the distance between the hook blade 17 and the ground, enabling the land leveling machine to flexibly adjust the land leveling depth and adapt to various land leveling needs.

[0043] Working principle:

[0044] The machine body 1 is connected to power equipment such as tractors via the front traction frame 5. When the power equipment moves forward, the traction frame 5 transmits power to the machine body 1, enabling the whole machine to move. The moving wheels 2 provide support and guidance to ensure the stable movement of the machine body 1. The hydraulic cylinder 4 extends, and its extended end pushes the nearby folding frame 3 to rotate outward around the pivot pin and unfold. When it is not in working condition and needs to be folded, the hydraulic cylinder 4 retracts, causing the folding frame 3 to rotate inward around the pivot pin and fold.

[0045] During operation, the two folding frames 3 of the tillage machine unfold to the sides. The forward movement of the tillage machine allows the hook blade 17 to hook up the residual film in the field. As the residual film is hooked up, large clods of soil are brought out. The toothed disc 14 set at the rear crushes the large clods of soil, breaking them into smaller pieces. Two triangular scrapers 7 are set at the rear of the toothed disc 14. The first scraper 7 pushes the crushed soil clods floating on the surface to the middle, and the second scraper 7 pushes them from the middle to the sides, completing the leveling of the surface soil clods.

[0046] When the hydraulic cylinder 4 flips and folds the folding frame 3, when the folding frame 3 flips to the side near the locking block 9 and squeezes the inclined surface of the locking block 9, the elastic plate 11 is squeezed, causing the locking block 9 and the fixing block 10 to move towards the direction of the traction frame 5 until the locking groove 8 and the locking block 9 are aligned. The elastic plate 11 drives the locking block 9 to pop out, and the locking block 9 enters the locking groove 8, locking the folding state of the folding frame 3. Since the two hydraulic cylinders 4 pull the two folding frames 3 synchronously, and there is a connecting rod 12 connecting the two locking blocks 9, the two locking blocks 9 are synchronously locked into the locking groove 8 on one side of the two folding frames 3. When it is necessary to lower the folding frame 3, the connecting rod 12 is pulled towards the direction of the traction frame 5, causing the two locking blocks 9 to move away from the locking groove 8, so that the locking blocks 9 leave the locking groove 8. Then, the two hydraulic cylinders 4 are used to lower the folding frames 3 on both sides. Example 2

[0047] like Figure 7-8 As shown, the difference between the second embodiment and the first embodiment is that: a rectangular frame 25 is provided on the front side of a plurality of toothed discs 14 on the body 1 and the folding frame 3, and a connecting plate 26 is hinged to the middle of both ends of the rectangular frame 25, and the upper end of the connecting plate 26 is fixed to the bottom of the corresponding body 1 and the folding frame 3.

[0048] The rotating shaft 16, which is fixedly installed with several hooks 17, is fixedly connected to the front side of the hinge point of the rectangular frame 25. A comb plate 27 is correspondingly provided above several hooks 17 on the rotating shaft 16. The comb plate 27 is provided with comb grooves 28 that correspond to the vertical position of the hooks 17 and match the width of the hooks 17.

[0049] A receiving box 29 is provided between the hook blade 17 and the toothed disc 14. The hook blade 17 protrudes downward to the bottom of the receiving box 29. The front side of the receiving box 29 is open, and the front end of the bottom plate of the receiving box 29 is bent upward at 15-25° to prevent the waste film collected by the receiving box 29 from leaking out.

[0050] The receiving box 29 has hinge plates 30 fixed at the middle of both ends. The upper end of the hinge plate 30 is hinged to the rear side of the hinge point of the rectangular frame 25, so that the receiving box 29 always maintains a vertical state with the receiving port facing upward during the rotation of the rectangular frame 25. The tail end of the electric push rod 19 is hinged to the corresponding machine body 1 and folding frame 3, and the telescopic end is hinged to the middle of the front end of the corresponding rectangular frame 25.

[0051] In this embodiment, the land preparation machine can also collect the hooked waste film through the hook blade 17 to ensure the continuous operation of the equipment. Specifically, the electric push rod 19 drives the front end of the rectangular frame 25 to rotate upward around the hinge point, which drives the hook blade 17 to pass upward through the comb groove of the comb plate, and drives the collection box 29 to rotate downward and move forward to the bottom of the comb plate 27, so that the waste film collected on the hook blade 17 falls into the collection box 29 through the comb plate 27 while the land preparation machine moves forward.

[0052] Of course, in this embodiment, the front end of the rectangular frame can also be driven downward around the hinge point by the electric actuator 19 to adjust the distance between the hook blade 17 and the ground.
