Description

Technical Field

[0001] This utility model relates to the field of mulching and seeding machine technology, and in particular to a cotton planting mulching and seeding device. Background Technology

[0002] A mulching seeder is an agricultural machine mainly used to cover the soil with plastic film during sowing to increase soil temperature, retain moisture and soil nutrients, thereby promoting crop growth. Mulching seeders are required when planting cotton.

[0003] Existing cotton planting and mulching seeding devices generally use pushers to press the mulch film together. However, the spacing between the pushers is relatively uniform, making it inconvenient to adjust the spacing according to the width of the field ridges, thus limiting their applicability. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned above, and to propose a cotton planting and mulching sowing device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a film covering device, comprising a base plate, three pulleys fixedly installed on the bottom surface of the base plate, an mounting plate fixedly installed on the surface of the base plate, two support frames fixedly installed on the surface of the base plate, a seeding box fixedly installed at the end of the two support frames away from the base plate, a feeding pipe fixedly installed on the bottom surface of the seeding box, a valve fixedly installed on the outer wall surface of the feeding pipe, a support plate fixedly installed on the surface of the base plate, a rotating shaft rotatably connected to the surface of the support plate, a film roller sleeved on the outer wall surface of the rotating shaft, a film roll wound on the outer wall surface of the film roller, diagonal bracing plates fixedly installed on both sides of the base plate, a guide shaft rotatably connected between the two diagonal bracing plates, an adjustment device provided on the surface of each of the two diagonal bracing plates, the adjustment device comprising two extension plates fixedly installed on the surface of the two diagonal bracing plates, a sliding rod fixedly installed between the two extension plates, two sliding plates slidably connected to the surface of the sliding rod, and a pressure roller fixedly installed on the bottom surface of the sliding plate. The pressure roller serves to compress and solidify the film.

[0006] Preferably, two support rods are fixedly installed on one side surface of the base plate. An L-shaped plate is fixedly installed on the surface of the two support rods away from the base plate. A vertical rod is fixedly installed on the bottom surface of the horizontal end of the L-shaped plate. A T-shaped plate is slidably connected to the surface of the vertical rod. A hinge plate is hinged to the bottom surface of the T-shaped plate. The end of the hinge plate away from the T-shaped plate is hinged to the slide plate. The hinge plate enables the slide plate to move on the surface of the sliding rod.

[0007] Preferably, an electric telescopic rod is fixedly installed on the bottom surface of the horizontal end of the L-shaped plate, and the output end of the electric telescopic rod is fixedly connected to the T-shaped plate. The electric telescopic rod enables the T-shaped plate to move on the surface of the upright.

[0008] Preferably, a limiting device is provided on one side surface of the base plate. The limiting device includes two L-shaped rods, which are fixedly installed on one side surface of the base plate. A U-shaped plate is fixedly installed on the end surface of the two L-shaped rods away from the base plate. A threaded rod is rotatably connected between the inner walls of the two ends of the U-shaped plate. A motor is fixedly installed on one end face of the U-shaped plate, and the output end of the motor is fixedly connected to the threaded rod. The motor drives the threaded rod to rotate.

[0009] Preferably, a round rod is fixedly installed between the inner walls of both ends of the U-shaped plate, and a movable plate is threadedly connected to the surface of the threaded rod. The threaded rod serves to move the movable plate on the surface of the round rod.

[0010] Preferably, a limiting circular plate is fixedly installed on the side of the movable plate, and the surface of the limiting circular plate has through holes. The limiting circular plate serves to limit the film roller on the rotating shaft.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting an adjustment device, firstly, the entire device is fixed to the moving device by a fixing plate. Then, the moving device moves the entire device to the sowing area. The base plate continues to move using pulleys. When the base plate moves the hopper to the pre-dug planting pit on the ground, the valve is opened, and the cotton seeds in the sowing box fall into the planting pit. Then, the mulch film body at one end of the mulch film roll is pulled around the guide shaft for mulching. At this time, the distance between the two pressure rollers is adjusted according to the actual situation. First, the electric telescopic rod is started. The start of the electric telescopic rod drives the T-shaped plate to move on the surface of the upright. The movement of the T-shaped plate on the surface of the upright drives the hinge plate to move. The two sliding plates are moved along the surface of the sliding rod, moving away from or closer to each other. This movement of the two sliding plates drives the two pressure rollers to move away from or closer to each other, thus changing the distance between them. When the two pressure rollers reach the appropriate position, the electric telescopic rod is turned off, and then the pressure rollers press the mulch film onto the ground, allowing the mulch film to be laid flat as the base plate moves, covering the sown area. Through the coordination of the above structure, the spacing of the pressure rollers can be adjusted according to the width of the field ridges, allowing the pressure rollers to better press and secure the mulch film.

[0013] 2. In this utility model, by setting a limiting device, when the mulch film body on the mulch film roll is used up and needs to be replaced with a new one, the motor is started first. The motor starts and drives the threaded rod to rotate. The rotation of the threaded rod drives the movable plate to move on the surface of the round rod. The movement of the movable plate on the surface of the round rod drives the limiting round plate to move. The movement of the limiting round plate causes it to detach itself from the surface of the rotating shaft. When the limiting round plate moves to the appropriate position, the motor can be turned off. Through the cooperation of the above structure, the limiting round plate can be separated from the rotating shaft, so that the mulch film roll is no longer blocked by the limiting round plate and can be easily disassembled from the rotating shaft, thus facilitating the replacement of the mulch film roll.

[0023] The specific settings and functions of the adjustment device 3 and the limit device 4 will be explained in detail below.

[0024] In this embodiment: the surfaces of the two inclined support plates 14 are provided with adjustment devices 3. The adjustment devices 3 include two extension plates 301. The two extension plates 301 are fixedly installed on the surfaces of the two inclined support plates 14. A slide rod 302 is fixedly installed between the two extension plates 301. Two slide plates 303 are slidably connected to the surface of the slide rod 302. A pressure roller 304 is fixedly installed on the bottom surface of the slide plate 303.

[0025] In this embodiment, the pressure roller 304 is used to compact the mulch film.

[0026] Specifically, two support rods 305 are fixedly installed on one side surface of the base plate 1. An L-shaped plate 306 is fixedly installed on the surface of the two support rods 305 away from the base plate 1. A vertical rod 307 is fixedly installed on the bottom surface of the horizontal end of the L-shaped plate 306. A T-shaped plate 308 is slidably connected to the surface of the vertical rod 307. A hinge plate 310 is hinged to the bottom surface of the T-shaped plate 308. The end of the hinge plate 310 away from the T-shaped plate 308 is hinged to the slide plate 303.

[0027] In this embodiment, the hinge plate 310 serves to move the slide plate 303 on the surface of the slide bar 302.

[0028] Specifically, an electric telescopic rod 309 is fixedly installed on the bottom surface of the horizontal end of the L-shaped plate 306, and the output end of the electric telescopic rod 309 is fixedly connected to the T-shaped plate 308. The electric telescopic rod 309 serves to move the T-shaped plate 308 on the surface of the upright 307.

[0029] In this embodiment: a limiting device 4 is provided on one side surface of the base plate 1. The limiting device 4 includes two L-shaped rods 41. The two L-shaped rods 41 are fixedly installed on one side surface of the base plate 1. A U-shaped plate 42 is fixedly installed on the end surface of the two L-shaped rods 41 away from the base plate 1. A threaded rod 43 is rotatably connected between the inner walls of the two ends of the U-shaped plate 42. A motor 44 is fixedly installed on one end face of the U-shaped plate 42. The output end of the motor 44 is fixedly connected to the threaded rod 43. When the mulch film on the mulch film roll 13 is used up and needs to be replaced, first start the motor 44. The motor 44 starts and drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the movable plate 46 to move on the surface of the round rod 45. The movement of the movable plate 46 on the surface of the round rod 45 drives the limiting round plate 47 to move. The movement of the limiting round plate causes it to detach from the surface of the rotating shaft 11. When the limiting round plate 47 moves to the appropriate position, the motor 44 can be turned off. Through the cooperation of the above structure, the limiting round plate 47 can be separated from the rotating shaft 11, so that the mulch film roll 12 is no longer blocked by the limiting round plate 47 and can be easily removed from the rotating shaft 11, thus facilitating the replacement of the mulch film roll 12.

[0030] Specifically, a round rod 45 is fixedly installed between the inner walls of both ends of the U-shaped plate 42, and a movable plate 46 is threadedly connected to the surface of the threaded rod 43.

[0031] In this embodiment, the threaded rod 43 serves to move the movable plate 46 on the surface of the round rod 45.

[0032] Specifically, a limiting circular plate 47 is fixedly installed on the side of the movable plate 46, and a through hole 48 is provided on the surface of the limiting circular plate 47.

[0033] In this embodiment, the limiting circular plate 47 serves to limit the film roller 12 on the rotating shaft 11.

[0034] Working principle: By setting the adjustment device 3, firstly, the entire device is fixed to the moving device by the fixed plate. Then, the moving device moves the entire device to the sowing area. Then, the base plate 1 continues to move using the pulley 2. When the base plate 1 moves the hopper to the planting pit dug in the ground, the valve 9 is opened. At this time, the cotton seeds in the sowing box 7 fall into the planting pit. Then, the mulch film body at one end of the mulch film roll 13 is pulled around the guide shaft 15 to lay the mulch film. At this time, the distance between the two pressure rollers 304 is adjusted according to the actual situation. First, the electric telescopic rod 309 is started. The start of the electric telescopic rod 309 drives the T-shaped plate 308 to move on the surface of the upright 307. The movement of the T-shaped plate 308 on the surface of the upright 307 drives the hinge plate 310 to move. The two sliding plates 303 are moved away from or closer to each other on the surface of the sliding rod 302. The movement of the two sliding plates 303 on the surface of the sliding rod 302 drives the two pressure rollers 304 to move away from or closer to each other. The movement of the two pressure rollers 304 changes the distance between them. When the two pressure rollers 304 move to the appropriate position, the electric telescopic rod 309 is turned off. Then, the pressure rollers 304 press the mulch film onto the ground, so that the mulch film is laid flat as the base plate 1 moves, covering the sown area. Through the cooperation of the above structure, the spacing of the pressure rollers 304 can be adjusted according to the width of the field ridge, so that the pressure rollers 304 can better press and fix the mulch film body. When the mulch film on the mulch film roll 13 is used up and needs to be replaced, first start the motor 44. The motor 44 starts and drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the movable plate 46 to move on the surface of the round rod 45. The movement of the movable plate 46 on the surface of the round rod 45 drives the limiting round plate 47 to move. The movement of the limiting round plate causes it to detach from the surface of the rotating shaft 11. When the limiting round plate 47 moves to the appropriate position, the motor 44 can be turned off. Through the cooperation of the above structure, the limiting round plate 47 can be separated from the rotating shaft 11, so that the mulch film roll 12 is no longer blocked by the limiting round plate 47 and can be easily removed from the rotating shaft 11, thus facilitating the replacement of the mulch film roll 12.
