Description

Technical Field

[0001] The present invention relates to the technical field of film laying equipment, and more specifically, to a film laying equipment for planting agricultural products. Background Art

[0002] In order to prevent soil moisture from evaporating before planting crops, it is necessary to cover the surface of the land to be planted with a laying film. Currently, when laying film on the land, a compression spring is set on the film pressing roller, and the wheel drives the film pressing roller to rotate.

The film pressing roller can only squeeze the laying film once when it contacts the ground, and the land and the laying film are prone to loose compaction. In order to achieve a better compaction effect, a reciprocating driving device is required, and the film pressing roller contacts the laying film multiple times to effectively compact the laying film in the area, which slows down the film laying efficiency.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] For example, see Figure 1-8 , the present invention provides the following technical solutions:

[0029] A film laying device for planting agricultural products, comprising a main frame 1, characterized in that a U-shaped mounting frame 2 is fixedly connected to the bottom surface of the main frame 1, a tape unwinding roller 3 is rotatably connected inside the U-shaped mounting frame 2, a laying film 20 is arranged inside the tape unwinding roller 3, two connecting frames 4 are symmetrically fixedly connected to the surface of the main frame 1, an arc-shaped guide rail 5 is fixedly connected between the two connecting frames 4, and a reciprocating driving component 6 is slidably arranged inside the arc-shaped guide rail 5;

[0030] The two opposite inner walls of the arc guide rail 5 are fixedly connected to an arc shell 7 with an opening at one end, and a connecting pipe 8 is connected to the side of the arc shell 7, and the end of the connecting pipe 8 is connected to a compressed air chamber 9 perpendicular to the main frame 1. A piston 10 is slidably arranged in the compressed air chamber 9, and a pressure rod 11 is fixedly connected to the axial position of the bottom surface of the piston 10, and a film pressing plate 12 is fixedly connected to the end of the pressure rod 11. Two linear guide rails 15 are symmetrically fixedly connected to the film pressing plate 12, and a plurality of propulsion rods 16 are slidably arranged between the two linear guide rails 15. A counterweight ball 17 is fixedly connected to the end of each propulsion rod 16, and a sliding ring 18 is fixedly connected between the two relative propulsion rods 16. Each adjacent An elastic band 19 is arranged between the push rod 16 and the film pressing plate 12, and an energy storage fitting is arranged between the two push rods 16 on the outer side of the arc guide rail 5 and the corresponding air compression chamber 9. Arc grooves 38 are opened on the two opposite sides of the arc guide rail 5, and a plurality of sliders 39 that slide with the arc grooves 38 are symmetrically fixedly connected on the side of the arc tooth plate 26. A first fixing plate 40 is bolted between the ends of the two air compression chambers 9, and a second fixing plate 41 is bolted between the air compression chamber 9 and the arc guide rail 5. A pushing frame 42 is fixedly connected between the two straight plates 27, and a plurality of wheels 35 are symmetrically rotatably connected to the side of the main frame 1, and the distance between the two wheels 35 is smaller than the length of the unwinding roller 3.

[0031] The working principle of the first embodiment is as follows: when laying film on the ground, the tail of the laying film 20 is fixed between the unwinding roller 3, the head is extended, and after passing through the bottom of the two wheels 35, the soil is used to cover it, pushing the wheels 35 of the main frame 1 and the unwinding roller 3 to rotate accordingly, and continuously laying film on the passing road surface. When the device is moving, the two sets of air-pushing plates perform reciprocating arc motion of a fixed distance in the arc shell 7. Each time they move downward in the arc shell 7, the gas is squeezed to drive the piston 10 in the air-compression chamber 9 to move downward. The piston 10 drives the pressure rod 11 and the film-pressing plate 12 to compact the soil and the laying film 20 at the bottom. The air-pushing plate is continuously pressed into the left arc shell 7 and continuously moved out of the right arc shell 7. Similarly, when the piston 10 in the right air-compression chamber 9 moves upward, the piston 10 in the left air-compression chamber 9 moves downward, and the laying film 20 and the soil at the bottom can be alternately reciprocated and compacted.

[0032] When the piston 10 moves upward, each weight ball 17 abuts against each other. When the film pressing plate 12 moves upward, the arc block 23 just fits into the arc slot 14 when the film pressing plate 12 moves to the maximum value. At this time, each weight ball 17 is in abutment state, and the elastic band 19 is not stretched. Then the film pressing plate 12 is pressed down. During the process, the weight ball 17 is fixed by the arc slot 14. As the film pressing plate 12 is continuously pressed down, the elastic band 19 is gradually stretched, and the distance between the weight balls 17 gradually increases. The pulling force of the bottom weight ball 17 on the upper side gradually increases until the magnet in the reciprocating push assembly 6 is aligned with the magnet on the energy storage matching part. Correspondingly, the film pressing plate 12 is in a film pressing state, and the bottom of the film pressing plate 12 is in close contact with the ground of the laying film 20. After the limit of the top counterweight ball 17 is released by magnet attraction, the elastic belt 19 pulls each counterweight ball 17 to move vertically toward the bottom, and each counterweight ball 17 collides with each other. The counterweight ball 17 closest to the film pressing plate 12 applies pressure to the bottom film pressing plate 12 multiple times. The film pressing plate 12 can press the laying film 20 and the ground multiple times through a single movement, and the original single contact that can only press once is improved to a single contact with multiple presses, thereby improving the compaction ability of the laying film 20.

[0033] For example 2, please refer to Figure 7-8 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, the energy storage matching part includes an energy storage block 21, the energy storage block 21 is fixedly connected to the propulsion rod 16, an energy storage rod 22 is slidably arranged on the energy storage block 21, one end of the energy storage rod 22 is fixedly connected to an arc-shaped clamping block 23, the other end of the energy storage rod 22 is fixedly connected to a second magnet 24, a return spring 25 is arranged between the second magnet 24 and the energy storage block 21, a matching ring 13 is fixedly connected to the side surface of the compressed air chamber 9, the matching ring 13 is slidably matched with the sliding ring 18, and an arc-shaped clamping groove 14 corresponding to the arc-shaped clamping block 23 is opened on the side surface of the matching ring 13.

[0034] Working principle of the second embodiment: When the film pressing plate 12 moves upward, it is affected by gravity, and the adjacent counterweight balls 17 abut against each other. As the film pressing plate 12 moves upward, each counterweight ball 17 also moves upward. When the counterweight ball 17 moves, it pushes the energy storage block 21 to move upward. The reset spring 25 always provides thrust to the arc block 23 during the movement. When the film pressing plate 12 moves to the specified position, the arc block 23 just fits into the arc groove 14 in the matching ring 13. At this time, each counterweight ball 17 is still in abutment. As the push plate gradually moves downward in the arc shell 7, the distance between the counterweight balls 17 gradually increases, and the elastic belt 1 9 The pulling force on the top counterweight ball 17 gradually increases. When the magnet on the reciprocating push assembly 6 is aligned with the second magnet 24, the magnet pulls the second magnet 24 to move. The second magnet 24 stretches the reset spring 25 and drives the energy storage rod 22 to move. The movement of the energy storage rod 22 drives the arc block 23 to disengage from the arc slot 14, releasing the limit on the counterweight ball 17, so that all the counterweight balls 17 are pressed toward the film pressing plate 12. Compared with the method of directly compacting the laying film only through the film pressing plate 12, the counterweight ball 17 presses the film pressing plate 12 multiple times, which can better compact the laying film 20 and the ground, further improving the compaction efficiency.

[0035] For example 3, please refer to Figure 3-6 , the third embodiment is improved on the basis of the first embodiment as follows, specifically, the reciprocating driving assembly 6 includes an arc-shaped toothed plate 26 that is slidably matched with the arc-shaped guide rail 5, two straight plates 27 are symmetrically fixedly connected to the surface of the main frame 1, a rotating shaft is passed through and rotatably connected between the two straight plates 27, a gear 28 is fixedly connected to the side surface of the rotating shaft, and the gear 28 is meshed with the arc-shaped toothed plate 26, a motor is arranged on the side of one straight plate 27, and the motor is connected to the rotating shaft to drive the gear 28 to reciprocate, and two arc-shaped driving rods 29 are symmetrically fixedly connected to the two opposite sides of the arc-shaped toothed plate 26, and a sliding arrangement is arranged between the two arc-shaped driving rods 29. There is a control plate 30 that slides with the arc shell 7, and a buffer is arranged on the arc drive rod 29. The buffer includes a block 31 fixedly connected to the arc drive rod 29, and an arc spring 32 is arranged between the block 31 and the control plate 30. The ends of the two arc drive rods 29 on the outer sides of the arc guide rail 5 are fixedly connected with a matching rod 33 that slides with the arc shell 7, and the ends of the matching rod 33 are fixedly connected with a first magnet 34. When the first magnet 34 moves to a state flush with the second magnet 24, it can be pulled to move. A positioning plate 36 is fixedly connected to the inner wall of the arc shell 7, and a vent 37 is opened on the positioning plate 36.

[0036] The working principle of the third embodiment of the present invention is as follows: the motor drives the rotating shaft to rotate back and forth, the rotating shaft drives the gear 28 to rotate back and forth, the gear 28 is meshed with the arc-shaped toothed plate 26, the arc-shaped toothed plate 26 can reciprocate a fixed distance on the arc-shaped guide rail 5, and during the movement of the arc-shaped toothed plate 26, the slider 39 moves along the arc-shaped groove 38, thereby improving the stability of the movement of the arc-shaped toothed plate 26.

[0037] The matching rod 33 is slidably matched with the positioning plate 36, and the maximum reciprocating distance of the arc tooth plate 26 is when the arc drive rod 29 abuts against the positioning plate 36. When the arc drive rod 29 abuts against the positioning plate 36, the first magnet 34 just corresponds to the second magnet 24, that is, each time the arc drive rod 29 moves toward one side to the maximum value, the limit on the arc block 23 and the arc slot 14 can be released, so that each counterweight ball 17 presses the film pressing plate 12 once.

[0038] The control plate 30 reciprocates in the arc-shaped shell 7. When the control plate 30 is pressed down, the compressed air pushes the film pressing plate 12 downward. Similarly, when the control plate 30 moves up, it drives the film pressing plate 12 to move upward. Each time the film pressing plate 12 is in close contact with the ground and the laying film 20, it waits for a short pause until the counterweight balls 17 are pressed, and then moves upward, giving the counterweight balls 17 sufficient time to collide with each other, thereby ensuring the integrity of each ground compaction.

[0039] When encountering higher ground, the control board 30 moves to push the film pressing plate 12 to exert too much pressure on the laying film 20, and the arc driving rod 29 still moves a fixed distance. The arc spring 32 is appropriately compressed according to the ground height, which can reduce the moving distance of the control board 30 in the arc shell 7, thereby appropriately adjusting the pressing height of the film pressing plate 12, and avoiding damage to the laying film 20 due to excessive force when compacting the laying film 20 on too high ground, thereby further improving the practicality of the device.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
