Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural and sideline products processing, in particular to an agricultural and sideline products processing cleaning pretreatment equipment. BACKGROUND

[0002] Agricultural and sideline products (such as potatoes and radishes) are generally mixed with some impurities such as sand, soil, short and broken stems, weeds and shriveled fruits, and sometimes are contaminated by dust, pesticides, manure, microorganisms and other pollutants. Therefore, cleaning must be performed before processing to ensure the cleanliness of the products and thus the quality of food. Bubble cleaning is to make air enter water to generate a large number of bubbles and continuously stir the water, and the gas erosion occurs in the interior and interface of the water to clean the washed objects. When the gas is sprayed into the cleaning tank at a certain speed, the pressure change causes the gas erosion phenomenon. The vegetables, water and air flow together to form a very complex solid-liquid-gas three-phase flow change, which makes the water in the cleaning tank and the cleaned objects roll, whirl and irregularly disturb, so that the contaminants on the surface of the vegetables are effectively removed and the contaminants adhered to the surface of the objects are accelerated to separate. However, since part of the agricultural and sideline products have more soil adhered to the surface, most of the soil is dissolved in the water to contaminate the cleaning water during the cleaning process, so that the cleaning water becomes dirty quickly, and the large particles of floating impurities are still mixed with the agricultural and sideline products to be cleaned.

DETAILED DESCRIPTION

[0025] like Figures 1 to 10 As shown, the present invention includes a front bracket 1, a conveying assembly, an extrusion assembly, a rear bracket 4, a roll-out assembly and a bellows 7. The present invention is described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the agricultural and sideline products processing and cleaning equipment includes a front bracket 1, a conveying component, an extrusion component, a rear bracket 4, a roll-out component and a bellows 7. The front bracket 1 is a "U"-shaped structure with the opening facing upward. Figure 6As shown, the conveyor assembly includes conveyor rollers 2 and a conveyor motor 24. Several conveyor rollers 2 are arranged sequentially from front to back and rotatably mounted within a front bracket 1. The conveyor motor 24 is fixed to the front bracket 1 and drives the conveyor rollers 2 to rotate synchronously in a clockwise direction. Specifically, the conveyor rollers 2 form two horizontal conveyor surfaces arranged one above the other and an inclined conveyor surface located between the two horizontal conveyor surfaces. Each pair of adjacent conveyor rollers 2 rotates synchronously via a synchronization mechanism 5, which can be a chain drive or a belt drive. If the synchronization mechanism 5 is a chain drive, it includes a sprocket 51 and a chain 52. The two sprockets 51 of the synchronization mechanism correspond to and are coaxially arranged with the two adjacent conveyor rollers 2. The chain 52 is positioned between the two sprockets 51 of the synchronization mechanism. The output end of the conveyor motor 24 is coaxially arranged with one of the conveyor rollers 2. When the conveyor motor 24 is in operation, it drives the rotation of that conveyor roller 2, thereby driving the synchronous rotation of all conveyor rollers 2.

[0027] like Figure 7 、 Figure 8 As shown, the extrusion assembly includes a roller frame 3, an extrusion roller 32 and an extrusion motor 35. The roller frame 3 is arranged above the conveying roller 2. Several extrusion rollers 32 are rotatably mounted on the roller frame 3. The extrusion motor 35 is fixed on the front bracket 1 to drive the extrusion rollers 32 to rotate synchronously and the rotation direction is counterclockwise. There is a mounting block 31 on the roller frame 3. The mounting block 31 is hinged to the front bracket 1 through a support shaft 36. There is a torsion spring loosely sleeved on the support shaft 36 between the mounting block 31 and the front bracket 1. Under the action of the torsion spring, the roller frame 3 is parallel to the inclined conveying surface formed by the conveying roller 2. Every two adjacent extrusion rollers 32 also achieve synchronous rotation through the synchronization mechanism 5. The synchronization mechanism 5 is a chain drive mechanism or a belt drive mechanism. The assembly method of two adjacent extrusion rollers 32 and the synchronization mechanism is the same as the assembly method of two adjacent conveying rollers 2 and the synchronization mechanism 5. As shown Figure 8 As shown, a driving gear 34 is fixed to the output end of the extrusion motor 35, and a transition gear 33 meshing with the driving gear 34 is rotatably mounted on the support shaft 36 through a bearing 38. The transition gear 33 is also meshed with a driven gear 37, and the driven gear 37 is coaxially arranged with one of the extrusion rollers 32.

[0028] When the squeezing roller 32 cooperates with the conveying roller 2 to squeeze the agricultural and sideline products, in order to avoid damage to the agricultural and sideline products, such as Figure 9 As shown, the squeezing roller 32 includes, from the inside out, a roller shaft 21, an inner pressure layer 22, and an outer pressure layer 23. The outer pressure layer 23 is more flexible than the inner pressure layer 22. The different softness of the inner and outer pressure layers 22 and 23 ensures that the roller 32 has elasticity while ensuring sufficient squeezing force on the soil clods on the surface of agricultural and sideline products.

[0029] The conveying roller 2 rotates to convey the agricultural and sideline products from front to back, and the squeezing roller 32 and the conveying roller 2 cooperate to squeeze and rub the agricultural and sideline products between them, thereby removing dirt blocks on the surface of the agricultural and sideline products.

[0030] like Figure 1 As shown, the rear support 4 is located at the rear side of the front support 1, and the roll-out assembly is a belt conveyor mechanism, which includes a conveyor belt 6, on which scrapers 61 are evenly arranged, and the conveyor belt 6 has through holes 62, through which the soil on the conveyor belt 6 falls. Figure 10 As shown, the rollout assembly also includes a rollout motor 67, an intermediate roller 65, a lower roller 63, and an upper roller 64. The lower roller 63, intermediate roller 65, and upper roller 64 are arranged in sequence from front to back and positioned inside the conveyor belt 6 to support it. The rollout motor 67 is fixed to the rear support 4, driving the rotation of the intermediate roller 65. A cam 66 is rotatably mounted within the rear support 4, contacting the lower portion of the conveyor belt 6. The cam 66 is also connected to the intermediate roller 65 via a synchronization mechanism 5. When the rollout motor 67 is in operation, it drives the rotation of the intermediate roller 65, thereby moving the conveyor belt 6. Simultaneously, the rotation of the intermediate roller 65 drives the rotation of the cam 66 via the synchronization mechanism 5. The rotation of the cam 66 vibrates the lower portion of the conveyor belt 6, thereby shaking off dust from the conveyor belt 6. To ensure that the intermediate roller 65 can drive the movement of the conveyor belt 6, the conveyor belt 6 is a synchronous belt with teeth on the intermediate roller 65 that operate synchronously with the conveyor belt 6. To facilitate the removal of agricultural and sideline products on the conveyor belt 6 from the rear support 4, an ear plate 41 is fixed to the rear side wall of the rear support 4, and the upper roller 64 is rotatably installed between the two ear plates 41, so that a portion of the conveyor belt 6 is removed from the rear support 4. The portion of the conveyor belt 6 between the middle roller 65 and the lower roller 63 is arranged at an angle, and the portion of the conveyor belt 6 between the middle roller 65 and the upper roller 64 is arranged horizontally.

[0031] like Figure 1 As shown, the bellows 7 is located at the top of the rear bracket 4, and air holes are evenly arranged at the bottom of the bellows 7. The bellows 7 is connected to the suction fan. When the suction fan is working, the air in the rear bracket 4 can enter the bellows 7 through the air holes, and then absorb the dust on the conveyor belt 6 in the rear bracket 4.

[0032] The present invention uses a conveying assembly to transfer agricultural and sideline products. During the conveying process, the squeezing roller of the squeezing assembly cooperates with the conveying roller to squeeze the agricultural and sideline products, thereby removing most of the dirt on the surface of the agricultural and sideline products. The agricultural and sideline products with some dirt removed fall onto the conveyor belt of the transfer-out assembly, and the conveyor belt is used to transfer the agricultural and sideline products out. During the transfer-out process, the suction fan causes the dust on the conveyor belt to be sucked into the bellows through the air holes, thereby adsorbing the dust attached to the surface of the agricultural and sideline products. By pre-treating the agricultural and sideline products to remove dirt, the efficiency of subsequent bubble cleaning is improved.
