Description

Technical Field

[0001] This utility model relates to the field of vegetable processing technology, specifically to an automatic recycling and compression device for vegetable processing waste. Background Technology

[0002] Vegetable processing enterprises generate a large amount of vegetable scraps, especially leafy vegetables such as bok choy, spinach, and cabbage. During processing, leaves that have been bitten by insects, rotten, or damaged need to be removed. These removed vegetable scraps have a high water content, are prone to rotting and spoilage, and take up a lot of space when piled up, making it difficult to collect and dispose of the waste in a harmless manner.

[0003] Chinese patent discloses a dehydration device for vegetable waste, publication number CN116222159A. This device uses a squeezing block and a pushing block installed in the squeezing chamber to squeeze out the water from the vegetable waste. This can avoid the problem of lacking equipment for dehydrating vegetable waste in the field. Although this dehydration device can remove some water from the vegetable waste, it is manually operated, the squeezing force is small, and the dehydration efficiency is not high. In addition, since it does not have a chopping function, the processed vegetable waste is still relatively loose, takes up a lot of space, and is not conducive to the subsequent harmless treatment of vegetable waste.

[0004] Chinese patent discloses a vegetable scrap compression processing machine (authorization announcement number CN220804927U). This patented technology has both chopping and dehydration functions, which can chop and compress vegetable scraps and dehydrate them. After processing, the moisture content of the waste residue is greatly reduced, which facilitates subsequent harmless treatment.

[0005] However, it has certain drawbacks: in the process of processing vegetable processing waste, it uses simple crushing and main shaft spiral fin conveying to process scraps without effectively compressing and deeply dehydrating the materials. This method results in large volumes of waste that are loosely piled up, which not only occupies a lot of transportation and storage space and increases logistics costs, but also makes the high moisture content waste easy to rot and deteriorate, breed bacteria and produce leachate, causing environmental pollution risks. Utility Model Content

[0006] The purpose of this invention is to provide an automatic recycling and compression device for vegetable processing waste, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic recycling and compression device for vegetable processing waste includes a dewatering cylinder. A discharge die head is fixedly connected through the right side surface of the dewatering cylinder, and two spiral rods are symmetrically and rotatably connected through the left side surface of the dewatering cylinder in the front-to-back direction. A gear is fixedly connected to the outer left end of the spiral rods. An L-shaped plate is fixedly connected to the rear end of the left side surface of the dewatering cylinder. A motor is fixedly connected to the left side surface of the L-shaped plate. A feeding hopper communicating with the interior is fixedly connected to the left end of the upper surface of the dewatering cylinder. A crushing mechanism is provided on the left side surface and inside the feeding hopper.

[0009] The right end of the dewatering cylinder is fixedly connected to a compression box that communicates with its interior.

A telescopic cylinder is fixedly connected to the upper surface of the compression box, and a pressure plate is fixedly connected to the telescopic end of the telescopic cylinder. A scraping mechanism is provided at the upper end of the front surface of the compression box.

[0010] As a further improvement of this utility model: the crushing mechanism includes two motors, one in front and one behind, and a crushing roller is fixedly connected to the output end of each of the two motors.

[0011] As a further embodiment of this utility model: the scraping mechanism includes an L-shaped plate II, a telescopic cylinder II is fixedly connected to the front surface of the L-shaped plate II, and a scraper is fixedly connected to the telescopic end of the telescopic cylinder II.

[0013] As a further embodiment of this utility model: the second motor is fixedly connected to the left side surface of the feed hopper, and the right end of the crushing roller is rotatably connected to the inner right side surface of the feed hopper.

[0014] As a further embodiment of this utility model: the rear end of the L-shaped plate is fixed to the front surface of the compression box, and the scraper moves through the front surface of the compression box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

Overall, this invention achieves synergistic optimization of waste reduction and resource recovery, significantly improving processing efficiency and economy. Attached Figure Description

[0025] Please see Figures 1-4 In this embodiment of the utility model, the automatic recycling and compression device for vegetable processing waste includes a dehydration cylinder 1. A discharge mold head 2 is fixedly connected through the right side surface of the dehydration cylinder 1, and two spiral rods 3 are symmetrically and rotatably connected through the left side surface of the dehydration cylinder 1 in the front-back direction. A gear 4 is fixedly connected to the outer left end of the spiral rod 3, and the two gears 4 mesh with each other. An L-shaped plate 5 is fixedly connected to the rear end of the left side surface of the dehydration cylinder 1, and a motor 6 is fixedly connected to the left side surface of the L-shaped plate 5. The output end of the motor 6 is fixedly connected to the left end of the rear spiral rod 3. A feeding hopper 7 connected to the inside of the upper left side surface of the dehydration cylinder 1 is fixedly connected to the left end of the upper left side surface of the dehydration cylinder 1. A crushing mechanism 8 is provided on the left side surface and inside of the feeding hopper 7. The crushing mechanism 8 includes two motors 9, which are fixedly connected to the left side surface of the feeding hopper 7. A crushing roller 10 is fixedly connected to the output end of each of the two motors 9. The right end of the crushing roller 10 is rotatably connected to the inner right side surface of the feeding hopper 7.

[0026] The discharge die head 2 has two discharge ports, which are directly opposite the screw rod 3, for discharging vegetable waste after dehydration;

[0027] The spiral fins on the two spiral rods 3 are 180° out of phase, which brings the two spiral fins close to each other and their positions are partially intersecting. The front spiral fin can penetrate into the pitch gap of the rear spiral fin, and the rear spiral fin can also penetrate into the pitch gap of the front spiral fin. In this way, when the front and rear spiral fins rotate inward, they can work together to squeeze the material between the two spiral rods 3, further improving the dehydration efficiency of vegetable waste.

[0028] Motor 6 drives the rear screw rod 3 to rotate, and under the action of gear 4, the other screw rod 3 will also rotate.

[0029] Two crushing rollers 10 are used to crush vegetable waste to facilitate subsequent dehydration.

[0030] exist Figure 1 , Figures 5-7 In the middle: The right end of the dewatering cylinder 1 is fixedly connected to a compression box 11 that is connected to its interior. The lower ends of the four sides of the compression box 11 are provided with drainage holes 12. The front surface of the compression box 11 is located below the drainage holes 12 and is movably connected to a baffle 13. The upper surface of the compression box 11 is fixedly connected to a telescopic cylinder 14. The telescopic end of the telescopic cylinder 14 is fixedly connected to a pressure plate 15. The outer surface of the pressure plate 15 is movably attached to the inner surface of the compression box 11. The upper end of the front surface of the compression box 11 is provided with a scraping mechanism 16. The scraping mechanism 16 includes an L-shaped plate 17. The rear end of the L-shaped plate 17 is fixedly connected to the front surface of the compression box 11. The front surface of the L-shaped plate 17 is fixedly connected to a telescopic cylinder 18. The telescopic end of the telescopic cylinder 18 is fixedly connected to a scraper 19. The scraper 19 movably penetrates the front surface of the compression box 11.

[0031] The telescopic cylinder 14 is preferably a hydraulic cylinder. In its initial state, it is in a retracted state. At this time, the pressure plate 15 is located above the dewatering cylinder 1. The pressure plate 15 is used to compress the vegetable waste, reduce the volume of the vegetable waste, and reduce transportation and storage costs (the compression stroke can be adjusted and controlled according to actual conditions to avoid squeezing the vegetable waste out of the drain hole 12).

[0032] Drain hole 12 is used to drain water from vegetable waste;

[0033] The left and right sides and the rear surface of the baffle 13 are respectively movable and fit against the left and right sides and the rear surface of the inside of the compression box 11, and its front surface is flush with the front surface of the compression box 11; the baffle 13 can be removed by pulling it forward; the lower surface of the compression box 11 has an opening for the discharge of compressed vegetable waste.

[0034] The telescopic cylinder 14 is preferably a pneumatic cylinder, and its initial state is a retracted state. At this time, the rear surface of the scraper 19 is flush with the inner front surface of the compression box 11, and the upper surface of the scraper 19 is on the same horizontal plane as the lower surface of the pressure plate 15. It is used to scrape off the vegetable waste adhering to the lower surface of the pressure plate 15.

[0035] The working principle of this utility model is as follows: Vegetable waste enters through the feed hopper 7, and the two motors 9 of the crushing mechanism 8 drive the crushing rollers 10 to crush the material. The crushed waste falls into the dewatering cylinder 1, and the motor 6 drives the two spiral rods 3 to rotate through the meshing of the gear 4. The material is squeezed by the interlocking spiral fins to achieve efficient dewatering. The dewatered waste is discharged through the discharge die 2 to the compression box 11. After all the waste is discharged into the compression box 11, the dewatering cylinder 1 stops working, and the telescopic cylinder 14 drives the pressure plate 15 to press down to complete the compression. The water is discharged through the drain hole 12, and the compressed waste is discharged through the opening below the baffle 13. The telescopic cylinder 18 pushes the scraper 19 to move horizontally to scrape off the waste adhering to the lower surface of the pressure plate 15, ensuring continuous operation of the device.
