Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery parts technology, and specifically refers to a membrane frame structure. Background Technology

[0002] Currently used agricultural machinery for film-laying seeding employs several rods to spread the mulch film flat for sowing. The structural principle is to first fix the mulch film, then let the rods use traction reaction force and the undulations of the terrain to pull the film. However, due to factors such as terrain, machine speed, and wind, as well as the structure of the film-laying plate (commonly including a support frame with U-shaped grooves, where the mulch film is wound onto the frame tube and then placed into the U-shaped groove), it's difficult to accurately position the mulch film, leading to poor flattening. This severely impacts subsequent sowing operations and causes losses for farmers. Utility Model Content

[0003] The purpose of this utility model is to provide a simple and reasonable structure that can ensure that the laid mulch film is straight, standardized and neat.

[0004] The purpose of this utility model is achieved as follows:

[0005] A film frame structure includes a support frame and a film baffle. The film baffle is provided with a guide rod, the support frame is provided with a sliding hole for the guide rod to slide, the support frame is provided with an adjustment device for controlling the film baffle to move closer to or further away from the support frame, the film baffle is provided with a first placement groove for facilitating the placement of the roll shaft, and the support frame is provided with a second placement groove.

[0006] In the above-mentioned membrane plate structure, the adjustment device includes a handwheel and a screw. One end of the screw is movably connected to the membrane plate, and the other end is fixedly connected to the handwheel. The support frame is provided with a threaded hole that cooperates with the screw.

[0007] In the above-mentioned membrane plate structure, the guide rod is located in the middle of the membrane plate and is set perpendicular to the membrane plate.

[0008] In the above-mentioned membrane plate structure, the support frame includes a first support rod and a second support rod connected to each other, and there are two membrane plates, which are located at the upper ends of the first support rod and the second support rod, respectively.

[0009] In the above-mentioned membrane plate structure, the second support rod is inclinedly arranged on one side of the upper end of the first support rod.

[0010] In the above-mentioned membrane structure, the angle between the first support rod and the second support rod is 91°-175°.

[0011] In the above-mentioned membrane plate structure, both the first placement slot and the second placement slot are U-shaped structures.

[0012] In the above-mentioned membrane plate structure, the openings of the placement slot one and the placement slot two are respectively arranged outward.

[0013] In the above-mentioned membrane panel structure, the support frame is a hollow structure.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] The membrane support plate of this utility model can be used in pairs, respectively set on both sides of the equipment, and used in conjunction with the membrane support tube. The mulch film can be wound on the sleeve or directly wound on the membrane support tube. The membrane support tube mainly plays a supporting role. Before laying the mulch film, it is necessary to adjust the position between the membrane support plate and the mulch film. The membrane support plate plays a limiting role and clamping resistance to prevent the mulch film from moving left and right. This can clamp the mulch film, prevent the mulch film from loosening and slipping, and fix the film. It also makes it easy to replace the membrane support plate. The operation is simple and convenient. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-3As shown: A film support structure includes a support frame 1 and a film baffle 2. The film baffle 2 is provided with a guide rod 21. The support frame 1 is provided with a sliding hole 22 for sliding the guide rod 21. The support frame 1 is provided with an adjustment device 3 for controlling the film baffle 2 to move closer to or further away from the support frame 1. The film baffle 2 is provided with a placement groove 23 for facilitating the placement of the roll shaft. The support frame 1 is provided with a placement groove 24. Specifically, when the film support tube is placed on the film support, the end of the film support tube is placed in the placement groove 1 and the placement groove 2. It serves as a front and rear limiter to prevent the membrane support tube from moving back and forth, ensuring the stability of the mulch film laying. The membrane support plate can be installed in pairs, one on each side of the equipment, in conjunction with the membrane support tube. The mulch film can be wound onto the sleeve or directly onto the membrane support tube. The membrane support tube mainly serves as a support. Before laying the mulch film, the position between the membrane support plate and the mulch film needs to be adjusted. The membrane support plate serves as a limiter, which can clamp the mulch film, prevent the mulch film from loosening and slipping, and fix the film. It also makes it easy to replace the membrane support plate. The operation is simple and convenient.

[0022] In the above-described membrane plate structure, the adjusting device 3 includes a handwheel 31 and a screw 32. One end of the screw 32 is movably connected to the membrane plate 2, and the other end is fixedly connected to the handwheel 31. The support frame 1 is provided with a threaded hole 33 that cooperates with the screw 32. The guide rod 21 is located in the middle of the membrane plate 2 and is perpendicular to the membrane plate 2. Specifically, this is to facilitate the adjustment of the position of the membrane plate. The threaded hole on the support frame can be directly formed on the support frame, or the support frame can be provided with a through hole with a nut at the through hole. The above structure is relatively simple and has stable performance. The screw 32 is connected to the lower end of the membrane plate 2. Specifically, this can play a better supporting and positioning role. The guide rod plays a major supporting role, and the screw plays a secondary supporting role and a positioning role, preventing the membrane plate from rotating around the guide rod.

[0023] In the above-mentioned membrane frame structure, the support frame 1 includes a first support rod 11 and a second support rod 12 connected to each other. There are two membrane baffles 2, which are located at the upper ends of the first support rod 11 and the second support rod 12, respectively. The second support rod 12 is inclined on one side of the upper end of the first support rod 11. The angle between the first support rod 11 and the second support rod 12 is 91°-175°. Specifically, this allows two rolls of mulch film to be placed directly on the membrane frame, improving the efficiency of mulch film laying. After one roll is used up, the other roll can be directly connected for use.

[0024] In the above-mentioned membrane frame structure, both the placement groove 23 and the placement groove 24 are U-shaped structures. Specifically, this can further play a positioning role, reduce wear between the membrane frame tube and the placement groove, and extend the service life of both.

[0025] In the above-mentioned membrane frame structure, the openings of the placement slot 1 23 and the placement slot 24 are respectively set outwards, specifically, this is to facilitate the placement of the mulch film.

[0026] In the above-mentioned membrane structure, the support frame 1 is a hollow structure. Specifically, this can reduce weight and save materials and production costs while ensuring normal use.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
