Description

Technical Field

[0001] This utility model relates to the field of mulching transplanter technology, and in particular to a mulching transplanter mulching film cutting length control device. Background Technology

[0002] A mulching transplanter is an agricultural machine used to automate the laying of mulch film and the transplanting of crop seedlings in the field. It unfolds the mulch film through an unwinding mechanism and covers the ridge surface, while a transplanting device precisely plants the seedlings into the holes in the mulch film. It combines the functions of mulching to retain moisture, suppress weeds, increase temperature, and achieve efficient transplanting. Suitable for cash crops such as vegetables, tobacco, and cotton, it can significantly improve planting efficiency, reduce labor costs, and optimize the crop growing environment.

[0003] In agricultural production, mulching transplanting technology is widely used. It effectively retains soil moisture, increases soil temperature, and suppresses weed growth, thereby improving crop yield and quality. As a key material in mulching transplanting, the precise control of the cut length and width of the mulch film is crucial for the mulching effect and subsequent agricultural production. However, existing mulch film cutting devices in mulching transplanting machines have several shortcomings. On the one hand, the cutting mechanism is usually a fixed structure, unable to flexibly adjust the cutting width of the mulch film according to actual needs. This results in the mulch film not being fully adapted to different crop planting scenarios, leading to waste or poor performance. On the other hand, the height and position adjustment of the cutting mechanism is inconvenient, making it difficult to ensure optimal contact between the cutting blade and the mulch film, affecting cutting accuracy and efficiency, and consequently making it difficult to accurately control the cut length. Furthermore, the cut scraps are often scattered randomly in the field, not only affecting the field environment but also increasing the difficulty of subsequent cleaning and recycling.

[0029] Example 1:

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a mulch transplanter mulch film cutting length control device, including a mounting plate 100, which is fixed on the mulch transplanter. The mounting plate 100 is used to support the installation of a lifting mechanism 200. The lifting mechanism 200 is provided at the bottom end of the mounting plate 100. By providing the lifting mechanism 200, it is easy to adjust the height position of the cutting mechanism 300, which is beneficial for cutting the mulch film, thereby achieving the purpose of controlling the length of the mulch film. The bottom end of the lifting mechanism 200 is mounted on the lifting mechanism 300.

The limiting groove 304 is provided to support the limiting sliding of the brackets 305.

[0032] Example 2:

[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, a limit frame 201 is fixedly installed at the bottom of the mounting plate 100, and a slide rod 203 is slidably arranged on the limit frame 201.

[0035] There are two limit frames 201, which are symmetrically arranged with the electric telescopic rod 202 as the center. The limit frames 201 are used to support the sliding of the slide rod 203.

[0036] Specifically, the slide bar 203 is cylindrical in shape, and its bottom end is fixedly connected to the top end of the housing 205.

[0037] The sliding rod 203, together with the limiting bracket 201, serves to limit the movement of the box 205, facilitating the vertical movement of the box 205.

[0038] Specifically, a limiting block 204 is fixedly installed at the top of the slide bar 203, and the limiting block 204 is in the shape of a circular plate.

[0039] There are two limit blocks 204, which are symmetrically arranged with the electric telescopic rod 202 as the center. The limit blocks 204 are set to prevent the box 205 from falling off the slide rod 203.

[0040] Specifically, a first motor 307 is fixedly installed on the inner wall of the housing 205. The first motor 307 is vertically arranged, and a first gear 308 is fixedly installed on the shaft end of the first motor 307. The first gear 308 is horizontally arranged.

[0041] The first motor 307 has forward and reverse rotation functions. The first motor 307 is configured to drive the first gear 308 to rotate.

[0042] Specifically, the rotating rod 301 is set horizontally, and a second gear 310 is fixedly installed on the rotating rod 301. The second gear 310 is set vertically, and the first gear 308 meshes with the second gear 310.

[0043] By providing a first gear 308 and a second gear 310, the first motor 307 drives the rotating rod 301 to rotate when it is working.

[0044] Example 3:

[0045] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, the bracket 305 is L-shaped, and the inner wall of the bracket 305 is rotatably connected to the third gear 315 and the cutting plate 317.

[0047] The bracket 305 is configured to support the rotation of the third gear 315 and the cutting blade 317. The third gear 315 is configured to mesh with the gear roller 313. The cutting blade 317 is configured to cut the mulch film.

[0048] Specifically, a first vertical plate 312 is fixedly installed at the bottom of the housing 205, and a gear roller 313 is rotatably connected to the first vertical plate 312. The gear roller 313 meshes with a third gear 315. A second vertical plate 302 is fixedly installed at the bottom of the housing 205, and a second motor 311 is fixedly installed on the second vertical plate 302. The shaft end of the second motor 311 is fixedly connected to one end of the gear roller 313.

[0049] The first vertical plate 312 is used to support the rotation of the gear roller 313. By setting the gear roller 313, it is easy to mesh with the third gear 315, so that when it rotates, it drives the third gears 315 on both sides to rotate. The second vertical plate 302 is used to support the installation of the second motor 311. The second motor 311 is used to drive the gear roller 313 to rotate.

[0050] Specifically, a first transmission wheel 306 is fixedly mounted on the third gear 315, and a second transmission wheel 316 is fixedly mounted on the cutting blade 317. A track 303 is meshed with the first transmission wheel 306 and the second transmission wheel 316.

[0051] The first transmission wheel 306, in conjunction with the track 303, is used to drive the second transmission wheel 316 to rotate, thereby driving the cutting blade 317 to rotate when the third gear 315 rotates.

[0052] Specifically, two take-up rollers 309 are fixedly installed on the first conveyor wheel 306.

[0053] The winding roller 309 is used to wind up the scraps after the mulch film is cut.

[0054] When using the mulching transplanter, the first motor 307 is started according to the required cutting width of the mulch film. The first motor 307 drives the first gear 308 to rotate. The first gear 308 meshes with the second gear 310, which in turn drives the second gear 310 to rotate. When the second gear 310 rotates, it drives the rotating rod 301 to rotate. The rotating rod 301 is provided with positive and negative threads, which drives the threaded sleeves 314 on both sides to move. When the threaded sleeves 314 on both sides move, they drive the brackets 305 on both sides to move towards or in opposite directions along the inner wall of the limiting slide groove 304. When the brackets 305 on both sides move, they drive the cutting blades 317 on both sides to move towards or in opposite directions until the cutting blades 317 on both sides move to a suitable distance, so as to cut the mulch film to an appropriate width.

[0055] After the spacing of the cutting blades 317 is adjusted, the second motor 311 is started. The second motor 311 drives the gear roller 313 to rotate. When the gear roller 313 rotates, it drives the third gears 315 on both sides to rotate. When the third gears 315 rotate, they drive the first transmission wheel 306 to rotate. When the first transmission wheel 306 rotates, it drives the second transmission wheel 316 to rotate through the track 303. When the second transmission wheel 316 rotates, it drives the cutting blades 317 to rotate, thereby achieving the purpose of driving the two cutting blades 317 to rotate. After the cutting blades 317 rotate, the height of the cutting blades 317 is adjusted by the electric telescopic rod 202. During the process of the mulching transplanter unfolding the mulch film through the unwinding mechanism and covering the ridge surface, the cutting blades 317 will cut the mulch film in the transmission.

[0056] After cutting a certain distance, the second motor 311 is turned off, and the cut scraps are then wound onto the take-up roller 309. The second motor 311 is then restarted. When the first conveyor wheel 306 rotates, it will drive the take-up roller 309 to rotate, which makes it easier for the take-up roller 309 to take up the cut scraps and prevents the cut scraps from being discarded at will.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
