Abstract
Description
Technical Field
[0001] This utility model relates to the field of vegetable primary processing technology, and in particular to a vegetable primary processing equipment. Background Technology
[0002] Vegetable primary processing equipment refers to mechanical equipment used for basic processing of vegetables from harvesting to deep processing or cooking. It is mainly used for operations such as washing, cutting, peeling, dehydration, and screening and grading, aiming to improve processing efficiency, ensure hygiene, and standardize product specifications.
[0003] According to the Chinese patent "A sorting table for primary processing of dried vegetables" (authorization announcement number "CN218797483U"), the feeding component, small fruit screening net and medium fruit screening net work together to sort dried vegetables of different sizes, thus facilitating the sorting of dried vegetables of different sizes.
[0004] In the aforementioned application, since the surface of the dried vegetables is mostly irregular, the dried vegetables are prone to clogging the sieve holes on the surface of the small and medium fruit screening screens during the conveying and screening process, thereby reducing the screening effect of the dried vegetables. Utility Model Content
[0005] Therefore, it is necessary to provide a vegetable primary processing device to address the problem that dried vegetables easily clog the sieve holes on the surface of small and medium fruit screening screens.
[0006] The device includes: a processing table, with a feed hopper fixedly connected to the top of the processing table; an anti-blocking mechanism, which includes several guide rods disposed on the top of the processing table, a screening frame slidably connected to the surface of the guide rods, a first screening conveyor belt and a second screening conveyor belt disposed on the surface of the screening frame, a vibrating motor fixedly connected to the bottom of the screening frame, several springs fixedly connected to the bottom of the screening frame, and two brush plates slidably connected to the inner wall of the screening frame.
[0007] In one embodiment, the inner wall of the screening rack is rotatably connected to two first pulleys and two second pulleys. The surfaces of the two first pulleys are driven to the inner surface of the first screening conveyor belt, and the surfaces of the two second pulleys are driven to the inner surface of the second screening conveyor belt.
[0008] In one embodiment, the rear end of the screening rack is fixedly connected to two servo motors, the output shaft of one of the servo motors is fixedly connected to one end of one of the first pulleys, and the output shaft of the other servo motor is fixedly connected to one end of one of the second pulleys.
[0009] In one embodiment, a combing rack is fixedly connected to the upper surface of the screening rack.
[0010] In one embodiment, two dispersing frames are fixedly connected to the surface of the screening rack, one of which has its surface located on the inner surface of the first screening conveyor belt, and the other has its surface located on the inner surface of the second screening conveyor belt. The dispersing frames prevent dried vegetables from adhering to the surfaces of the first and second pulleys, thereby reducing wear between the first and second pulleys and the first and second screening conveyor belts.
[0011] In one embodiment, a rubber block is fixedly connected to the bottom end of the guide rod, the top end of the rubber block is fixedly connected to the bottom end of the spring, and the bottom end of the rubber block is fixedly connected to the top of the processing table. The rubber block reduces the transmission of vibration force generated by the screening rack to the processing table, thereby reducing noise generation.
[0012] In one embodiment, the inner wall of the brush plate is threaded with a screw, the surface of which is threaded to the inner wall of the screening frame. The screw facilitates the replacement of the brush plate on the screening frame, ensuring effective cleaning of both the first and second screening conveyors.
[0013] In one embodiment, the top of the brush plate and the bottom of the combing frame are both curved into an arc shape.
[0014] Beneficial effects
[0015] 1. By cooperating with a vibrating motor and a spring, the screening frame, the first screen conveyor belt, and the second screen conveyor belt are vibrated, thereby reducing the probability of dried vegetables clogging the first and second screen conveyor belts. The brush plate scrapes the screen holes of the first and second screen conveyor belts in the transmission, thereby preventing dried vegetables from clogging the first and second screen conveyor belts and ensuring the screening effect of the first and second screen conveyor belts on dried vegetables of different sizes.
[0016] 2. The vegetable dried vegetables fed to the top of the first screen conveyor are combed by the combing frame to prevent the vegetable dried vegetables from accumulating on the top of the first screen conveyor, thereby reducing the probability of the first screen conveyor and the second screen conveyor being blocked, and ensuring the screening effect of vegetable dried vegetables of different sizes.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The following is combined with Figures 1-5 This invention describes a vegetable primary processing equipment.
[0027] In one embodiment, a vegetable primary processing device includes: a processing table 100, with a feed hopper 200 fixedly connected to the top of the processing table 100; an anti-blocking mechanism 300, which includes a plurality of guide rods 308 disposed on the top of the processing table 100, a screening frame 301 slidably connected to the surface of the guide rods 308, a first screening conveyor belt 304 and a second screening conveyor belt 305 disposed on the surface of the screening frame 301, a vibration motor 306 fixedly connected to the bottom of the screening frame 301, a plurality of springs 307 fixedly connected to the bottom of the screening frame 301, and two brush plates 310 slidably connected to the inner wall of the screening frame 301.
[0028] It should be noted that the vibration motor 306 typically has a set of adjustable eccentric blocks installed at each end of the rotor shaft, and the excitation force is obtained by utilizing the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks.
[0029] The sieve holes on the surface of the first sieve conveyor belt 304 are smaller than the sieve holes on the surface of the second sieve conveyor belt 305. Both the first sieve conveyor belt 304 and the second sieve conveyor belt 305 are nylon components, which have high strength, good wear resistance, and a low coefficient of friction.
[0030] The low coefficient of friction of the first screen conveyor belt 304 and the second screen conveyor belt 305 makes the movement of dried vegetables on the first screen conveyor belt 304 and the second screen conveyor belt 305 smoother, reducing the accumulation and blockage caused by excessive friction.
[0031] Spring 307 is a component made of 304 stainless steel, which has good elasticity, strength and corrosion resistance.
[0032] Both the brush plate 310 and the bristles on its top are made of polyurethane, which has high elasticity and wear resistance, and can quickly deform and return to its original shape when subjected to external force. At the same time, the wear resistance of the polyurethane brush plate 310 and the bristles on its top is also excellent, and it can withstand frequent friction with the screen holes on the surface of the first screen conveyor belt 304 and the second screen conveyor belt 305 without damage.
[0033] In this embodiment, when the dried vegetables need to be graded and screened, multiple collection boxes are placed in the corresponding positions of the processing table 100 in sequence, and dried vegetables are poured into the feed hopper 200. The vibration motor 306 is manually turned on and drives the first screen conveyor belt 304 and the second screen conveyor belt 305 to drive. The dried vegetables in the feed hopper 200 fall onto the top of the first screen conveyor belt 304. The operation of the vibration motor 306 generates a vibration force on the screening frame 301. The vibration force is transmitted to the surface of the spring 307, thereby increasing the vibration amplitude of the screening frame 301, so that the first screen conveyor belt 304 and the second screen conveyor belt 305 vibrate. The vibrating first screen conveyor belt 304 spreads the dried vegetables piled on the top, so that the dried vegetables are dispersed on the top of the first screen conveyor belt 304, avoiding the dried vegetables from accumulating on the top of the first screen conveyor belt 304.
[0034] The first screen conveyor belt 304 in the transmission process screens the dried vegetables during transport, allowing small dried vegetables to fall through the screen holes on the first screen conveyor belt 304 into the collection frame below. The first screen conveyor belt 304 drives the larger dried vegetables to the second screen conveyor belt 305 in the transmission process. The second screen conveyor belt 305 in the transmission process screens the dried vegetables during transport, allowing medium-sized dried vegetables to fall through the screen holes on the second screen conveyor belt 305 into the collection frame below. The larger dried vegetables retained at the top of the second screen conveyor belt 305 are transported to another collection frame, thus completing the multi-stage screening of the dried vegetables.
[0035] The bristles on the top of the brush plate 310 extend into the sieve holes on the surfaces of the first sieve conveyor belt 304 and the second sieve conveyor belt 305, so that the brush plate 310 scrapes the first sieve conveyor belt 304 and the second sieve conveyor belt 305 in transmission. Then, through the vibration of the first sieve conveyor belt 304 and the second sieve conveyor belt 305, the dried vegetables are prevented from clogging in the sieve holes on the surfaces of the first sieve conveyor belt 304 and the second sieve conveyor belt 305.
[0036] like Figure 2-3 As shown, the inner wall of the screening frame 301 is rotatably connected to two first pulleys 303 and two second pulleys 302. The surfaces of the two first pulleys 303 are connected to the inner surface of the first screen conveyor belt 304, and the surfaces of the two second pulleys 302 are connected to the inner surface of the second screen conveyor belt 305. The rear end of the screening frame 301 is fixedly connected to two servo motors 313. The output shaft of one servo motor 313 is fixedly connected to one end of one of the first pulleys 303, and the output shaft of the other servo motor 313 is fixedly connected to one end of one of the second pulleys 302. The upper surface of the screening frame 301 is fixedly connected to a combing frame 311, and the surface of the screening frame 301 is fixedly connected to two dispersing frames 312. The surface of one dispersing frame 312 is located on the inner surface of the first screen conveyor belt 304, and the surface of the other dispersing frame 312 is located on the inner surface of the second screen conveyor belt 305.
[0037] In this embodiment, two servo motors 313 are manually turned on. The output shafts of the two servo motors 313 rotate, driving one of the first pulleys 303 and the second pulley 302 to rotate. The rotation of the first pulley 303 drives the first screen conveyor belt 304, and the rotation of the second pulley 302 drives the second screen conveyor belt 305, thereby conveying and screening the dried vegetables.
[0038] like Figure 2 As shown, a rubber block 309 is fixedly connected to the bottom end of the guide rod 308, the top end of the rubber block 309 is fixedly connected to the bottom end of the spring 307, the bottom end of the rubber block 309 is fixedly connected to the top of the processing table 100, a screw 314 is threadedly connected to the inner wall of the brush plate 310, and the surface of the screw 314 is threadedly connected to the inner wall of the screening rack 301. The top of the brush plate 310 and the bottom of the combing rack 311 are both curved into an arc shape.
[0039] It should be noted that the rubber block 309 and the feed hopper 200 are mounted on the top of the processing table 100 by bolts.
[0040] Rubber block 309 is a high-molecular elastomer material that has both viscosity and elasticity. This property is called viscoelasticity. Viscosity means that rubber will generate internal friction during deformation under stress, which will convert some mechanical energy into heat energy and dissipate it. This allows rubber block 309 to consume vibration energy during vibration, thereby playing a role in shock absorption.
[0041] Working principle: The vibrating motor 306 and servo motor 313 are manually turned on, which in turn drives the first screen conveyor belt 304 and the second screen conveyor belt 305. The dried vegetables in the feed hopper 200 fall onto the top of the first screen conveyor belt 304. The operation of the vibrating motor 306 generates a vibration force on the screening frame 301. The vibration force is transmitted to the surface of the spring 307, which increases the vibration amplitude of the screening frame 301, thereby causing the first screen conveyor belt 304 and the second screen conveyor belt 305 to vibrate. The vibrating first screen conveyor belt 304 spreads the dried vegetables piled on top, dispersing them on the top of the first screen conveyor belt 304 and preventing them from accumulating. The brush plate 310 scrapes the first screen conveyor belt 304 and the second screen conveyor belt 305 during operation, thereby preventing the dried vegetables from clogging in the screen holes on the surface of the first screen conveyor belt 304 and the second screen conveyor belt 305.
[0042] It should be noted that the processing table 100, feeding hopper 200, screening rack 301, second pulley 302, first pulley 303, screw 314, vibration motor 306, and servo motor 313 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the vibration motor 306 and servo motor 313 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
