Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, specifically to a waste collection device for agricultural product testing. Background Technology

[0002] In agricultural product quality and safety testing laboratories, the sample pretreatment process generates a large amount of complex waste, including but not limited to fruit and vegetable residues, grain husks, extraction residues, and organic solvents used for cleaning utensils. These wastes are typically characterized by being a mixture of dry and wet materials, being loose and dusty, and being prone to spoilage and odor.

[0003] The authorized publication number "CN223267959U" describes "a waste collection device for agricultural product testing, including a collection box and a crushing box. A feeding hopper is installed through the upper surface of the collection box. A crushing component for crushing waste is installed inside the collection box below the feeding hopper. This utility model has a crushing box installed inside the collection box below the feeding hopper, and two sets of crushing rollers are installed inside the crushing box. By pouring agricultural waste into the feeding hopper and starting the motor, the two sets of crushing rollers rotate simultaneously to crush the agricultural product. Then, the telescopic rod pushes the extrusion plate to crush the residue, so that the waste liquid in the residue flows from the filter plate at the bottom of the residue box to the waste liquid collection box, realizing the separation of residue and liquid. This makes it easier for workers to clean the residue and also avoids the growth of bacteria inside the collection box to a certain extent." The aforementioned patent allows the waste liquid in the slag to flow from the filter plate at the bottom of the slag box to the waste liquid collection box, achieving slag-liquid separation and facilitating cleaning by workers. It also helps to prevent bacterial growth inside the collection box to some extent. However, during use, the aforementioned patent can easily generate dust when throwing loose, dry waste. These suspended particles not only pollute the laboratory environment and affect the accuracy of instruments, but may also contain allergens or trace amounts of pesticide residues, posing a potential threat to the respiratory health of operators. At the same time, the mixed organic waste decomposes rapidly at room temperature, producing an unpleasant odor and affecting the experimental environment. Utility Model Content

[0004] This invention provides a waste collection device for agricultural product testing. By using a negative pressure mechanism, a stable downward airflow is formed at the feeding port of the processing box. This airflow can effectively suppress and suck up light particles such as dust and fibers generated during feeding, preventing them from escaping into the laboratory air. This ensures the cleanliness of the testing environment and the health and safety of the operators from the source. At the same time, the sucked-in air passes through an activated carbon baffle before being discharged, where odor molecules and trace pollutants are adsorbed, ensuring the cleanliness of the discharged air and avoiding secondary pollution. Furthermore, the negative pressure mechanism and the crushing mechanism are powered by one motor, which can simultaneously complete the two core functions of waste crushing and negative pressure dust removal with only one motor. This significantly reduces energy consumption and manufacturing costs, and achieves automated operation that starts as soon as the material is fed.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a waste collection device for agricultural product testing, comprising: Processing box 1, with a solid-liquid separation plate 3 fixedly connected to the bottom of the processing box 1; The crushing mechanism is located inside the processing box 1; The negative pressure mechanism comprises two sets, both housed within the processing chamber 1 and connected to the crushing mechanism. Each set includes a mounting component, a linkage component, an activated carbon baffle 5, and a negative pressure fan blade rod 6. The mounting component is located within the processing chamber 1, the negative pressure fan blade rod 6 is rotatably connected to the processing chamber 1, the linkage component is mounted on the negative pressure fan blade rod 6 and connected to the crushing mechanism, and the activated carbon baffle 5 is installed within the processing chamber 1. The extrusion mechanism is located inside the processing box 1.

[0016] In this implementation plan: the solid-liquid separation plate 3 separates the waste liquid from the solid in the waste, and completes the reasonable treatment of different wastes. The dust generated during the testing process is easy to fly when feeding, which affects the air quality of the laboratory and may cause cross-contamination. At the same time, some loose waste occupies a lot of space and reduces the collection efficiency. The negative pressure fan blade rod 6 creates a negative pressure inside the treatment box 1. When feeding, a weak downward airflow is formed, which effectively sucks in and suppresses the dust from rising. The sucked air passes through a replaceable activated carbon partition 5 before being discharged, adsorbing odor molecules in the waste gas to ensure that the discharged air is clean. The bottom of the treatment box 1 is equipped with a drain port to discharge the waste liquid.

[0017] Specifically, the crushing mechanism includes crushing rollers 9, crushing motors 14, and synchronous gears 11. There are two crushing rollers 9, both of which are rotatably connected inside the processing box 1. The crushing motor 14 is fixedly connected to one side of the outer surface of the processing box 1, and the output end of the crushing motor 14 is fixedly connected to one end of one of the crushing rollers 9. There are two synchronous gears 11, each of which is fixedly connected to one end of each crushing roller 9.

[0018] In this embodiment, the model of the crushing motor 14 can be selected from those available on the market as needed, which will not be elaborated here. The crushing motor 14 controls the rotation of the crushing roller 9, and the two crushing rollers 9 rotate synchronously through the synchronous gear 11 to complete the crushing of waste materials.

[0019] Specifically, the installation components include a partition plate 8 and a protective net 13. The partition plate 8 is fixedly connected to the inside of the processing box 1 near the top, and the protective net 13 is fixedly connected to one side of the outer surface of the processing box 1.

[0020] In this embodiment: the partition plate 8 wraps the negative pressure fan blade rod 6 and the activated carbon partition plate 5 so that it will not be affected when waste is put in. The protective net 13 protects the negative pressure fan blade rod 6 to avoid the influence of the external environment.

[0021] Specifically, the linkage components include a drive gear 17, a timing belt 16, and a driven gear 15. The drive gear 17 is fixedly connected to one end of the crushing roller 9, and the driven gear 15 is fixedly connected to one end of the negative pressure fan blade rod 6. The timing belt 16 is sleeved on the driven gear 15 and the drive gear 17, and the timing belt 16 meshes with the driven gear 15 and the drive gear 17.

[0022] In this embodiment, the drive gear 17, the synchronous belt 16, and the driven gear 15 work together to control the rotation of the negative pressure fan rod 6 while the crushing roller 9 rotates. Furthermore, the dimensions of the drive gear 17 and the driven gear 15 can be adjusted to achieve different rotation speeds for the crushing roller 9 and the negative pressure fan rod 6.

[0023] Specifically, the extrusion mechanism includes an extrusion motor 4, an extrusion screw 10, and an extrusion plate 2. There are two extrusion screws 10, both of which are rotatably connected inside the processing box 1. There are two extrusion motors 4, both of which are fixedly connected to one side of the outer surface of the processing box 1. The output end of each extrusion motor 4 is fixedly connected to one end of each extrusion screw 10. The extrusion plate 2 is slidably connected inside the processing box 1, and the top two ends of the extrusion plate 2 are threadedly connected to the two extrusion screws 10 respectively.

[0024] In this embodiment, the model of the extrusion motor 4 can be selected from those available on the market as needed, which will not be elaborated here. The extrusion motor 4 controls the extrusion screw 10 to rotate, so that the extrusion plate 2 moves inside it to complete the solid-liquid separation.

[0025] Specifically, a guide plate 7 is fixedly connected to the top of the processing box 1, and a discharge plate 12 is installed on one side of the outer surface of the processing box 1.

[0026] In this embodiment: the guide plate 7 facilitates the precise feeding of waste material between the two crushing rollers 9, and the discharge plate 12 can discharge the waste material, thus completing the use.

[0027] During use, ensure the device is powered on and in standby mode. Feed the agricultural product testing waste into the processing chamber 1 through the guide plate 7 at the top. When the crushing motor 14 starts, it drives the two crushing rollers 9 to rotate in opposite directions, shredding and pressing the waste to achieve initial solid-liquid separation and volume reduction. Simultaneously, through the drive gear 17, synchronous belt 16, and driven gear 15, the negative pressure fan blade 6 begins to rotate at high speed, creating a downward weak airflow below the feeding port of the processing chamber 1, i.e., a negative pressure environment. This effectively suppresses dust rising during feeding and draws in any potentially dispersed dust and odors. The drawn-in air must pass through the activated carbon baffle 5, where odor molecules and fine particles are adsorbed and filtered before finally being discharged, ensuring a clean laboratory environment. After being pressed and shredded by the crushing rollers 9, the liquid components inside the waste are initially separated, and the separated liquid falls off along with the solid waste. Waste liquid flows through the holes in the solid-liquid separation plate 3 into the bottom of the treatment tank 1, while solid waste is trapped on the solid-liquid separation plate 3. The waste liquid collected at the bottom of the tank can be discharged periodically through the drain port at the bottom of the tank. When a certain amount of solid waste accumulates on the solid-liquid separation plate 3, two extrusion motors 4 can be started to drive two extrusion screws 10 to rotate synchronously. The extrusion plate 2, which is threaded to the extrusion screws 10, moves to one side under the drive of the screws. The extrusion plate 2 strongly extrudes the solid waste on the solid-liquid separation plate 3 to further squeeze out the residual water and achieve deep dehydration. After the extrusion and dehydration are completed, the discharge plate 12 on the side of the treatment tank 1 can be opened, and the compressed dry waste can be easily removed. The equipment should be opened periodically to replace or regenerate the activated carbon partition 5 to maintain its continuous deodorization effect. The crushing roller 9, solid-liquid separation plate 3 and the inner wall of the tank should be cleaned to prevent cross-contamination and keep the equipment hygienic.

[0028] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
