Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to a device for laying mulch film for agricultural planting. Background Technology

[0002] With the development of agriculture, sowing and seedling raising are the most important processes in agricultural planting. The seed is sown while the soil is turned over by the ridging seeder, which increases the looseness of the soil and improves the efficiency of sowing. After the seeds are sown, a protective film needs to be covered on the soil to ensure the humidity and temperature of the seed germination environment.

[0003] Currently, when laying mulch film, existing equipment simply lays the film directly on the already sown land, causing the film to come into contact with the sown soil. However, in actual planting, there needs to be a certain distance between the mulch film and the germination point to prevent the seedlings from coming into contact with the mulch film after the seeds germinate, which could cause the film to overheat and scorch the seedlings.

[0004] Based on this, the present invention designs an agricultural mulch film laying device to solve the above problems. Summary of the Invention

[0015] Furthermore, the unwinding mechanism includes an unwinding gear rotatably mounted on the fixed half-frame plate and cooperating with the linkage gear.

The telescopic shaft passes through the fixed half-frame plate and is rotatably connected to the fixed half-frame plate.

[0016] Furthermore, the film-stretching mechanism includes a movable rack that is slidably connected to the surface of the fixed half-frame plate and engages with a drive gear. A sliding block is fixedly mounted on the surface of the movable rack. The sliding block is slidably connected to the inner wall of the fixed half-frame plate.

Both grooved sliders are connected to the inner wall of the grooved platform through compression springs. The surfaces of both grooved sliders are fixedly connected to one end of the extrusion cylinder, and the other end of the extrusion cylinder is connected to the symmetrical end of the extrusion cylinder.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention uses a film-pulling mechanism to pull the mulch film roll in the opposite direction of the traction device, and unwinds it under the action of an unwinding mechanism. At this time, the relative movement makes the vertically facing position of the nailer located at the same point on the ground. When the movement reaches the end of the film-pulling mechanism, the film-pulling mechanism releases the first end of the mulch film roll. The controller sends a feedback signal to the nailer, and the nailer extends a fixing nail to fix the first end of the mulch film roll to the ground, thereby achieving the purpose of automatically positioning and fixing the first end of the mulch film roll.

[0021] 2. This invention utilizes the gathering effect between two bending plates to gather soil into the trapezoidal space formed by the two bending plates and the compression block. A reciprocating mechanism drives the two bending plates to move towards each other, while the compression block moves vertically downwards under the action of the reciprocating mechanism, compressing the soil between the two bending plates and the compression block. This creates trapezoidal raised paths on both sides of the sown soil, ensuring the stability of the mulch film support. This achieves automatic support of the mulch film, preventing seeds from being damaged by heat and sun exposure after germination. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0037] like Figure 1 , Figure 9 and Figure 10 As shown, in one embodiment, an agricultural mulch film laying device is provided, the device comprising:

[0038] Seeder 1: Includes a frame platform 101 mounted on the seeder 1. Two connecting columns 102 for docking with traction equipment are fixedly installed on the surface of the frame platform 101. A fixed half-frame plate 103 is fixedly installed on the surface of the frame platform 101.

[0039] Soil-gathering mechanism 2 includes four bent plates 201 mounted on the frame 101 for gathering soil. The surfaces of every two bent plates 201 are slidably connected to a compression block 202 for compressing soil. It also includes two nailers 204 mounted on the fixed half-frame plate 103 for fixing the unwinding end of the mulch film roll 203. It also includes a soil-covering scraper 205 mounted on the frame 101 for scraping soil. A rotating roller for guiding the mulch film roll 203 is rotatably mounted on the fixed half-frame plate 103. Both nailers 204 are connected to the output end of an external controller.

[0040] Reciprocating mechanism 3: Driven by the rotating mechanism 4, the bending plate 201 and the compression block 202 compress the soil;

[0041] Unwinding mechanism 5: Used to unwind the plastic film roll 203;

[0042] Film pulling mechanism 6: Used to pull the mulch film for positioning;

[0043] Drive mechanism 7: used to drive the bending plate 201 and the compression block 202 closer to the ground.

[0044] In practical application, when sowing seeds and laying mulch on land, the device is connected to the traction equipment via the connecting column 102. The traction equipment then drives the frame platform 101 to move. Upon reaching the sowing position, the traction equipment stops moving. Figure 10 As shown, the driving mechanism 7 drives the bending plate 201 closer to the ground. At this time, the traction device continues to move and turns the soil for sowing. When the first end of the film roll 203 is close to the sowing position, as... Figure 9 As shown, the film-pulling mechanism 6 pulls the film roll 203 in the opposite direction of the traction device's movement, and the unwinding mechanism 5 unwinds it. During this process, the relative movement causes the nailers 204 to be vertically aligned at the same point on the ground. When the film-pulling mechanism 6 reaches its end, it releases the beginning of the film roll 203. A signal is sent to the nailers 204 via the controller, and the nailers extend fixing nails to secure the beginning of the film roll 203 to the ground, thus achieving automatic positioning and fixing of the beginning of the film roll 203. As the traction device moves, it also turns over excess soil that has been sown, such as... Figure 10As shown, the soil is gathered into the trapezoidal space formed by the two bending plates 201 and the compression block 202 through the converging effect between the two bending plates 201. The reciprocating mechanism 3 drives the two bending plates 201 to move towards each other, while the compression block 202 moves vertically downwards under the action of the reciprocating mechanism 3, compressing the soil between the two bending plates 201 and the compression block 202, achieving a compaction effect. This serves two purposes: firstly, it supports the mulch film during installation; secondly, the compacted soil does not become loose. Therefore, a compaction effect is formed on both sides of the sown soil. The trapezoidal raised channels ensure the stability of the mulch film support, thereby achieving automatic support of the mulch film and preventing seeds from being burned by heat after germination. After the soil is gathered, the soil at the edge of the mulch film is turned up by the soil scraper 205 as the mulch film is laid. The turned-up soil falls on the edge of the mulch film, thereby achieving the purpose of automatically covering and fixing the edge of the mulch film. After the mulch film is laid, the mulch film is cut by an external cutting device. At the same time, the first end of the cut mulch film roll 203 is clamped again by the film pulling mechanism 6 to facilitate the next mulch film laying operation.

[0045] like Figure 10 , Figure 11 and Figure 12 As shown, in a preferred embodiment of the present invention, the reciprocating mechanism 3 includes a sliding rod 301 fixedly connected to the surface of the bending plate 201. A reciprocating spring 302 is fixedly installed on the surface of the sliding rod 301. One end of the reciprocating spring 302 away from the sliding rod 301 is connected to the linkage table 303. A straight sliding groove that cooperates with the sliding rod 301 is provided on the linkage table 303. A swing rod 304 is rotatably installed on the surface of the sliding rod 301. One end of the swing rod 304 away from the sliding rod 301 is rotatably connected to a vertical rod 305. The vertical rod 305 passes through the linkage table 303 and is slidably connected to the linkage table 303. One end of the vertical rod 305 is connected to the compression block 202. A rotating platform 306 is rotatably installed on the surface of the linkage table 303. An annular wave block 307 that cooperates with the other end of the vertical rod 305 is fixedly installed on the surface of the rotating platform 306. The surface of the rotating platform 306 is connected to the rotating mechanism 4. The linkage table 303 is fixedly connected to the driving mechanism 7.

[0046] In practical applications, when the drive mechanism 7 completes the operation of bringing the bending plate 201 close to the ground, as in the embodiments of the present invention... Figure 10 As shown, at this time, the rotating mechanism 4 drives the rotating table 306 to rotate. The rotation of the rotating table 306, through the cooperation of the annular wave block 307 and the vertical rod 305, drives the vertical rod 305 to reciprocate in the vertical direction, thereby driving the compression block 202 to reciprocate in the vertical direction, as shown. Figure 12As shown, the movement of the vertical rod 305 simultaneously drives the two sliding rods 301 to reciprocate in opposite directions through the swing of the swing rod 304, which in turn drives the two bending plates 201 to reciprocate in opposite directions. At this time, the two bending plates 201 cooperate with the compression block 202 to continuously compress the soil between them, thereby achieving the purpose of compacting the soil and improving the stability of the mulch film support.

[0047] like Figure 5 and Figure 8 As shown, in another preferred embodiment of the present invention, the rotating mechanism 4 includes a bevel gear set 401 whose output end is fixedly connected to the surface of the rotating table 306. The input end of the bevel gear set 401 is fixedly connected to the driven gear 402. The driven gear 402 is rotatably connected to the driving mechanism 7. The driven gear 402 meshes with the driving gear 403. The driving gear 403 is connected to the output end of the rotating motor 404. The rotating motor 404 is fixedly mounted on the driving mechanism 7. A linkage gear 405 is coaxially fixedly mounted on the surface of the driving gear 403.

[0048] In practical application, when the drive mechanism 7 completes the operation of bringing the bending plate 201 close to the ground, the drive gear 403 meshes with the film stretching mechanism 6, and simultaneously the linkage gear 405 meshes with the unwinding mechanism 5. Figure 5 and Figure 8 As shown, the rotating motor 404 starts running at this time. The operation of the rotating motor 404 drives the driven gear 402 to rotate through the gear transmission action, and then drives the rotating table 306 to rotate through the bevel gear set 401. The operation of the reciprocating mechanism 3 compresses the soil through the two bending plates 201 and the compression block 202, thereby achieving the purpose of compacting the soil.

[0049] like Figure 4 and Figure 5 As shown, in another preferred embodiment of the present invention, the unwinding mechanism 5 includes an unwinding gear 501 rotatably mounted on the fixed half-frame plate 103 and cooperating with the linkage gear 405. A telescopic shaft 502 for fixing the mulch film roll 203 is coaxially fixedly mounted on the surface of the unwinding gear 501. The telescopic shaft 502 passes through the fixed half-frame plate 103 and is rotatably connected to the fixed half-frame plate 103.

[0050] In practical applications, after the bending plate 201 is brought close to the ground by the drive mechanism 7, as in the embodiment of the present invention... Figure 5 As shown, at this time, the operation of the drive mechanism 7 drives the linkage gear 405 to mesh with the unwinding gear 501, and the operation of the rotating mechanism 4 drives the unwinding gear 501 to rotate, thereby driving the mulch film roll 203 to unwind through the telescopic rotating shaft 502, so as to achieve the purpose of automatic unwinding when laying mulch film.

[0051] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, the film stretching mechanism 6 includes a movable rack 601 that is slidably connected to the surface of the fixed half-frame plate 103 and cooperates with the drive gear 403. A sliding block 602 is fixedly installed on the surface of the movable rack 601. The sliding block 602 is slidably connected to the inner wall of the fixed half-frame plate 103. A groove platform 603 is fixedly installed on the surface of the sliding block 602. Two groove sliders 604 are slidably installed on the inner wall of the groove platform 603. Both groove sliders 604 are connected to the inner wall of the groove platform 603 through compression springs 605. The surfaces of both groove sliders 604 are fixedly connected to one end of the extrusion cylinder 606, and the other end of the extrusion cylinder 606 is connected to the symmetrical end of the extrusion cylinder 606. An extrusion contact 607 is fixedly installed on the surface of each groove slider 604. A triangular contact plate 608 that cooperates with the two extrusion contacts 607 is fixedly installed on the surface of the fixed half-frame plate 103. The triangular contact plate 608 is connected to the input end of an external controller.

[0052] In practical application, when the driving mechanism 7 drives the bending plate 201 close to the ground, the driving mechanism 7 drives the drive gear 403 to mesh with the moving rack 601. The operation of the rotating mechanism 4 drives the moving rack 601 to move in the opposite direction of the traction device. This, in turn, drives the groove platform 603 to move in the opposite direction of the traction device via the sliding block 602. The movement of the groove platform 603 pulls the mulch roll 203 towards the position of the triangular contact plate 608 via the extrusion cylinder 606. Simultaneously, the movement of the unwinding mechanism 5 drives the mulch roll 203 to unwind. As the groove platform 603 drives the extrusion contact 607 to contact the triangular contact plate 608, the triangular contact plate 608 sends a feedback signal to the controller, causing the nailer 204 to nail and fix the first end of the mulch roll 203. Simultaneously, the limiting effect of the triangular contact plate 608... Figure 7 As shown, the two extrusion contacts 607 move in opposite directions, which in turn drive the two extrusion cylinders 606 to move in opposite directions through the two grooved sliders 604, thereby achieving the purpose of positioning and fixing the first end of the mulch roll 203.

[0053] like Figure 1 As shown, in another preferred embodiment of the present invention, the driving mechanism 7 includes a driving motor 701 fixedly mounted on the frame 101, a driving screw 702 fixedly mounted on the output end of the driving motor 701, the driving screw 702 and the screw slide 703 forming a helical pair transmission, the driven gear 402 being rotatably connected to the screw slide 703, the rotating motor 404 being fixedly mounted on the screw slide 703, two soil-covering scrapers 205 being fixedly mounted on the screw slide 703, and the linkage table 303 being fixedly connected to the screw slide 703.

[0054] In practical application, when the traction equipment moves to the sowing position, the drive motor 701 starts to run. The operation of the drive motor 701 drives the screw slide 703 to move vertically downward through the screw pair transmission, and then drives the bending plate 201 to move downward close to the ground through the linkage table 303. At the same time, it drives the rotating mechanism 4 to mesh with the unwinding mechanism 5, and also drives the rotating mechanism 4 to mesh with the film pulling mechanism 6, thereby achieving the purpose of automatic coordination and transmission.

[0055] like Figure 1 As shown, in another preferred embodiment of the present invention, the device further includes a soil turning mechanism 8, which includes a plurality of forward turning shovels 801 and reverse turning shovels 802 fixedly installed on the screw slide 703. The plurality of forward turning shovels 801 and reverse turning shovels 802 all pass through the frame platform 101 and are slidably connected to the frame platform 101. A seeder 803 is fixedly installed on the surface of the frame platform 101.

[0056] In practical applications, when the drive mechanism 7 starts running, as in the embodiments of the present invention... Figure 1 As shown, at this time, the downward movement of the screw slide 703 drives the forward turning shovel 801 and the reverse turning shovel 802 to insert into the soil. The movement of the traction device drives the forward turning shovel 801 to turn the soil, while the seeder 803 releases seeds in a quantitative manner. Then, the reverse turning shovel 802 turns the soil in the opposite direction to cover it, thereby achieving the purpose of automatic soil turning and sowing.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention.
