Description

Technical Field

[0001] The invention belongs to the technical field of agricultural mulch film covering, and in particular relates to an agricultural mulch film covering device. Background Art

[0002] Ground film is a ground covering film, usually a transparent or black PE film, but also a green or silver film. It is used for ground covering to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote plant growth. Ground film looks thin, but it plays a considerable role. It can not only increase ground temperature, retain water, soil, and fertilizer and improve fertilizer efficiency, but also has many functions such as weed control, disease and insect prevention, drought and waterlogging resistance, salt inhibition and seedling protection, improve near-ground light and heat conditions, and make the product hygienic and clean.

[0003] Existing mulching machines are mainly powered by mechanized power and require workers who can operate power machinery to complete. During the operation of existing agricultural mulching devices, the steps for installing the mulch roll are relatively cumbersome, and it is not convenient to disassemble when replacing the mulch, which increases the disassembly and installation time of workers, reduces efficiency, and reduces the practicality of the device. Secondly, during the laying of existing mulch, the diameter of the mulch roll will gradually become smaller, which makes the tension of the mulch between the actively rotating mulch roll and the pressure wheel gradually smaller, resulting in the mulch being too loose, causing the mulch to be damaged, affecting the heat preservation and moisture retention effect. In addition, with the loss of rural population and the gradual reduction of labor force, it is necessary to develop a simple, easy-to-operate mechanical device for mulch covering that reduces the burden of rural labor.

An elastic membrane 155 is fixedly connected to the inner end of the T-shaped shaft 153. A permanent magnet 156 is fixedly installed on the outer side of the T-shaped shaft 153. A compression spring 157 is fixedly connected between the outer side of the T-shaped shaft 153 and the rotating sleeve 151. The function of the compression spring 157 is to generate a magnetic field for attracting the permanent magnet 156 by energizing the electromagnetic ring 152, thereby driving the T-shaped shaft 153 to move close to the electromagnetic ring 152 and compressing the compression spring 157. During the movement of the electromagnetic ring 152, the air passage 154 will be connected to the part of the rotating sleeve 151 close to the material storage box 10, so that the air passage 154 and the elastic membrane 155 The compressed gas in the film enters the inner side of the rotating sleeve 151, so that the elastic film 155 no longer expands.

The uniform laying of the film and the faster rotation speed of the driven wheel 19 will cause the rotation speed of the column 161 to accelerate, so that the sliding block 163 slides to the outside of the cross cavity 162 and the stretching amount of the tension spring 164 increases, so that the hydraulic oil in the oil shell 165 will push the sliding rod 166 to move and squeeze the reset spring 167, and the connecting rod 17 and the adjusting roller 18 follow the movement, thereby driving the ground film to be tightened, and entering to keep the tightness of the front and rear ground film laying at a constant level, thereby solving the problem that the diameter of the ground film roll will gradually become smaller during the existing ground film laying process, which makes the progress of the ground film tension between the actively rotating ground film roll and the pressure wheel 4 gradually smaller, resulting in the film being too loose, causing the ground film to be damaged, affecting the heat preservation and moisture retention effect.

[0024] Among them, the connecting frame 8 is fixedly connected to the main shaft 1 and the material box 10, the two arc plates 12 are fixedly connected to the material box 10, the bottom end of the V-shaped plate 21 has many notches, the rotating sleeve 151 is rotatably connected to the material box 10 and has good sealing performance, the T-shaped shaft 153 is sleeved with the material box 10 and has good sealing performance, the curved surface of the rotating sleeve 151 is fixedly connected to the middle of the driven wheel 19, the permanent magnet 156 is horizontally aligned with the electromagnetic ring 152, the column 161 is fixedly connected to the rotating sleeve 151, the connecting block 168 is fixedly connected to the material box 10, the sliding rod 166 is fixedly connected to the connecting rod 17, the interior of the oil shell 165 is filled with an appropriate amount of hydraulic oil, and the interior of the airway 154 and the elastic membrane 155 is filled with The function of the fully compressed gas is to pass the ground film through the curved surface of the adjusting roller 18 and complete the initial ground film laying work, and then the driving motor 13 works to drive the driving wheel 14 to rotate, and the driving wheel 14 drives the driven wheel 19, the clamping mechanism 15, and the adjusting mechanism 16 to rotate through the transmission belt 20, and the ground film roll between the two clamping mechanisms 15 follows the rotation, and at the same time, the traction machinery drives and the device to lay the ground film. During the process, the pressing wheel 4 will press the ground film, and the rotating sealing wheel 7 will guide the soil to the edge of the ground film for sealing. The V-shaped plate 21 will make the soil compacted by the traction machinery fluffy, and guide larger stones or hard soil blocks to both sides to prevent them from damaging the ground film.

[0025] Working principle:

[0026] Before using the present invention, the traction frame 9 is connected to the traction machine, and a proper amount of ground film rolls are placed inside the material box 10;

[0027] When the present invention is used, the electromagnetic ring 152 is energized to generate a magnetic field that attracts the permanent magnet 156, thereby driving the T-shaped shaft 153 to move close to the electromagnetic ring 152 and squeeze the compression spring 157. During the movement of the electromagnetic ring 152, the airway 154 will be connected with the part of the rotating sleeve 151 close to the material storage box 10, so that the compressed gas in the airway 154 and the elastic membrane 155 enters the inner side of the rotating sleeve 151, and then the elastic membrane 155 no longer expands. When the permanent magnet 156 contacts the electromagnetic ring 152, the inner end of the T-shaped shaft 153 is flush with the inner wall of the material storage box 10, and the bottom ground film roll falls on the top of the two arc plates 12. Then the electromagnetic ring 152 is powered off, and the compression spring 157 pushes the T-shaped shaft 153 to reset and enter the paper roller in the middle of the ground film roll, and the expanded elastic membrane 155 fixes the paper roller, thereby completing the rapid installation of the ground film roll;

[0028] The ground film is passed through the curved surface of the adjusting roller 18, and the initial ground film laying work is completed. Then the driving motor 13 works to drive the driving wheel 14 to rotate. The driving wheel 14 drives the driven wheel 19, the clamping mechanism 15, and the adjusting mechanism 16 to rotate through the transmission belt 20. The ground film roll between the two clamping mechanisms 15 rotates accordingly. At the same time, the traction machinery drives and the device to lay the ground film. During the process, the pressing wheel 4 will press the ground film, and the rotating sealing wheel 7 will guide the soil to the edge of the ground film for sealing. The V-shaped plate 21 will make the soil compacted by the traction machinery fluffy, and guide larger stones or hard soil blocks to both sides to prevent them from damaging the ground film.

[0029] The driving motor 13 will adjust the speed according to the remaining amount of ground film (through the control module of the driving motor in the prior art, it is gradually adjusted according to the consumption speed of the ground film in the actual process, which is the prior art and will not be described in detail), that is, when there is less ground film on the paper roller, the speed of the driving motor 13 is faster, thereby ensuring the uniform laying of the ground film, and the speed of the driven wheel 19 becomes faster, which will cause the speed of the column 161 to increase, so that the sliding block 163 slides to the outside of the cross cavity 162 and increases the stretching amount of the tension spring 164, so that the hydraulic oil in the oil shell 165 will push the sliding rod 166 to move and squeeze the reset spring 167, and the connecting rod 17 and the adjusting roller 18 will move accordingly, thereby driving the ground film to be tightened;

[0030] When the ground film roll is replaced after use, the electromagnetic ring 152 is energized, and the T-shaped shaft 153 moves close to the electromagnetic ring 152, so that the remaining paper roll falls from between the two arc plates 12 to the inside of the roll-receiving shell 11, and then the new ground film falls on the upper part of the arc plate 12, the electromagnetic ring 152 is de-energized, and the T-shaped shaft 153 is reset, thereby completing the replacement of the ground film roll.
