Description

Technical Field

[0001] This utility model relates to the technical field of mulch film production and processing equipment, specifically a quantitative addition device for mulch film production. Background Technology

[0002] Mulch film, also known as ground cover film, is usually transparent or black PE film, but green and silver films are also available. It is used for agricultural ground cover. Mulch film can not only increase soil temperature, retain water, retain soil, and retain fertilizer to improve fertilizer efficiency, but also has multiple functions such as weed control, pest and disease prevention, drought and flood resistance, salt suppression and seedling protection, improvement of near-surface light and heat conditions, and product hygiene and cleanliness. In the current mulch film production process, a raw material adding device is required to add raw materials for mulch film production. However, when using the existing raw material adding device, the presence of clumps between plastic particles can easily cause fluctuations in the amount of raw materials added, resulting in errors in the amount of raw materials added each time. To avoid this phenomenon, certain improvements need to be made to the current raw material adding device to meet the requirements. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 5The illustrated quantitative addition device for mulch film production includes a frame 1. Two sets of support legs 17 are fixedly installed on the bottom surface of the frame 1. Each support leg 17 has several expansion bolts 18 at its bottom, which secure the support legs 17 to the ground, preventing the frame 1 from moving during the addition of mulch film raw materials and ensuring the stability of the frame 1. A storage bin 2 and a conveying pipe 3 are fixedly installed on the upper surface of the frame 1. The feed end of the conveying pipe 3 extends into the interior of the storage bin 2. The internal rotating connection of the conveying pipe 3 is a spiral conveying rod 4. A rotating motor 5 is fixedly installed on the left side of the conveying pipe 3. The output end of the rotating motor 5 is fixedly connected to the left end of the spiral conveying rod 4. A mounting bracket 6 is fixedly installed on the upper surface of the conveying pipe 3. A rotating motor 7 is fixedly installed on the mounting bracket 6. A turntable 8 is drivenly connected to the output end of the rotating motor 7. A connecting column 9 is fixedly installed on the side of the turntable 8 away from the rotating motor 7. The connecting column 9 is sleeved inside the movable frame 10. The movable frame 10 has a "U" shaped structure. The bottom end of the movable frame 10 is slidably connected to... A connecting rod 13 has a rubber hammer 11 fixedly mounted at its bottom end. A limit block 25 is fixedly mounted on the side of the mounting frame 6 away from the rotary motor 7. The inner wall of the limit block 25 is slidably connected to the outer surface of the connecting rod 13. The installation of the limit block 25 restricts the movement trajectory of the connecting rod 13, thereby preventing the connecting rod 13 from deviating from its movement trajectory during movement, thus ensuring the stability of the moving frame 10 and achieving the effect of reciprocating up and down movement of the rubber hammer 11. A connecting plate 14 is also connected to the frame 1. A connecting cylinder 15 is fixedly installed on the upper surface of plate 14. The connecting cylinder 15 has a feed inlet at the top and a discharge outlet at the bottom. The discharge end of the conveying pipe 3 is connected to the feed inlet of the connecting cylinder 15. A metering hopper 19 is rotatably connected to the inside of the connecting cylinder 15 via a rotating shaft. The metering hopper 19 is cylindrical and has several strip grooves on its outer surface. The outer surface of the metering hopper 19 is in contact with the inner wall of the connecting cylinder 15. A stepper motor 20 is fixedly rotatably mounted on the outer surface of the connecting cylinder 15. The output end of the stepper motor 20 is fixedly connected to the rotating shaft of the metering hopper 19.

[0021] To facilitate the adjustment of the amount of raw material added, several electric push rods 21 are fixedly installed in the groove of the metering hopper 19. A sealing plate 22 is fixedly installed at the telescopic end of the electric push rod 21. The size of the sealing plate 22 is the same as the size of the strip groove. By moving the sealing plate 22 with the electric push rod 21, the capacity of the strip groove can be adjusted, thereby adjusting the amount of raw material added.

[0022] To make the discharge more concentrated, two sets of fixing rods 23 are fixedly installed on the bottom surface of the frame 1, and the bottom ends of the two sets of fixing rods 23 are fixedly installed with the discharge hopper 24.

[0023] In order to absorb some of the vibration, a damping support 12 is also fixedly installed between the frame 1 and the connecting plate 14. The damping support 12 includes a spring and a damper 26, with the damper 26 installed inside the spring.

[0024] To facilitate the control of the machine's start and stop as well as the extension and retraction of the electric push rod 21, a controller 16 is fixedly installed on the outer surface of the frame 1. The rotary motor 5, rotary motor 7, stepper motor 20, and electric push rod 21 are all controlled by the controller 16. In this embodiment, a DTW type electric push rod is used.

[0025] To protect the controller 16 from accidental contact and dust, a protective shell 27 is fixedly installed on the outer surface of the frame 1. A protective cover 28 is rotatably hinged to the side of the protective shell 27 away from the frame 1, and the controller 16 is located inside the protective shell 27.

[0026] To facilitate the opening and closing of the protective shell 27, a locking block 29 is fixedly installed on the right side of the protective cover 28, and a locking frame 30 is fixedly installed on the right side of the protective shell 27, with the locking block 29 snapped into the inside of the locking frame 30.

[0027] The working process of this embodiment is as follows:

[0028] In operation, the operator first adjusts the extension length of the electric push rod 21 using the controller 16. The power provided by the electric push rod 21 drives the sealing plate 22 to move, and the amount to be added is determined according to the needs. Then, the worker turns on the rotary motor 5, rotary motor 7, and stepper motor 20 using the controller 16. The power provided by the rotary motor 5 drives the screw conveyor 4 to rotate, so that the screw conveyor 4 transports the mulch film raw material particles inside the storage box 2 through the conveying pipe 3 to the inside of the connecting cylinder 15. At the same time, the rotating metering hopper 19 is used to achieve quantitative and uniform addition of raw materials. During the addition of raw materials, the power provided by the rotary motor 7 drives the turntable 8 to rotate, so that the turntable 8 drives the connecting column 9 to rotate. In turn, the connecting column 9, together with the limit block 25, drives the moving frame 10 and the rubber hammer 11 to move back and forth, thereby knocking and vibrating the conveying pipe 3 to break up the clumps and avoid the problem of fluctuation in the amount of mulch film raw material added due to clumping. This achieves the purpose of quantitative addition of mulch film raw materials.
