Description

Technical Field

[0001] This utility model relates to the technical field of vegetable screening devices, and more specifically to a screening device for removing dehydrated vegetable debris. Background Technology

[0002] Dehydrated vegetables, also known as rehydrated vegetables, are dried vegetables made by washing and drying fresh vegetables to remove most of their water content, while preserving their original color and nutritional components. Dehydrated vegetables are easy to store and transport, and can effectively regulate the seasonal fluctuations in vegetable production. Compared to other fresh vegetables, dehydrated vegetables are smaller, lighter, rehydrate easily, and convenient to transport and consume. They can be used in various pickles, preserved vegetables, and other dishes. After dehydration, vegetables need to be screened to remove impurities such as mud and debris.

[0003] For example, a dehydrated vegetable screening device with prior art publication number CN222306433U achieves automatic screening by setting up an electrical box and a vibrator, and by the frequent vibration of the vibrator driving the vibration of the electrical box, the whole machine vibrates.

[0004] However, the existing technology has the following problems in use: In traditional screening devices, dehydrated vegetables flow from the feed hopper onto the screen, but due to the limited diameter of the feed hopper's discharge port, the dehydrated vegetables tend to accumulate in large quantities, making it difficult to disperse and screen quickly, thus affecting the screening effect and efficiency. Therefore, this invention provides a dehydrated vegetable debris removal and screening device with high uniformity of material dispersion. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a dehydrated vegetable debris removal and screening device. By setting a rotatable and openable screen inside the screen box, it is convenient to clean both the screen and the inside of the screen box, greatly facilitating subsequent maintenance. Furthermore, by using a rotary motor to drive the lead screw to move the nut block back and forth within the slider, the dehydrated vegetables can be evenly distributed on the screen, which helps to improve the screening effect and efficiency, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dehydrated vegetable debris removal and screening device, comprising a mounting frame, a sieve box at the top of the mounting frame, a sieve screen inside the sieve box, one side of the sieve screen being fixed to the sieve box via a connecting plate, the other side of the sieve screen being rotatably connected to the sieve box, a slider at the rear top of the sieve box, grooves on both sides of the top of the sieve box, the bottom of the slider being slidably disposed within the grooves, a guide rod fixedly disposed inside the slider, a nut block sleeved on the guide rod, a feed hopper fixedly passing through the nut block, and a drive mechanism for adjusting the movement of the nut block fixedly disposed on the slider.

[0007] In a preferred embodiment, the driving mechanism includes a lead screw that is rotatably disposed inside the slider, and one end of the lead screw passes through a nut block and is threadedly connected to the nut block.

[0008] In a preferred embodiment, a rotary motor is fixedly provided on one side of the slider. One end of the output shaft of the rotary motor passes through the slider and is fixed to the lead screw. The rotary motor drives the lead screw to rotate, thereby realizing the automatic movement of the feed hopper.

[0009] In a preferred embodiment, both sides of the screen box are threaded with fastening bolts, and the slider is fixed to the screen box by the fastening bolts. The fastening bolts fix the slider, making it easy for the operator to quickly adjust the position of the slider.

[0010] In a preferred embodiment, a cover plate is hinged to the top of the feed hopper, and an electromagnetic valve is fixedly installed at the bottom of the feed hopper. The electromagnetic valve controls the amount of dehydrated vegetables to ensure the normal screening operation of the screen. After use, the cover plate is closed to prevent dust and impurities from contaminating the inside of the feed hopper.

[0011] In a preferred embodiment, a feeding pipe is fixedly provided at the front end of the sieve box, and a partition is fixedly provided at the top of the feeding pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figures 1-5 This utility model provides a dehydrated vegetable debris removal and screening device, including a mounting frame 1. The mounting frame 1 is provided with a screen box 2 at the top. The screen box 2 is provided with a screen mesh 3 inside. The top of one side of the screen mesh 3 is fixed to the screen box 2 through a connecting plate 4. The other side of the screen mesh 3 is rotatably connected to the screen box 2. The top rear side of the screen box 2 is provided with a slider 5. The top two sides of the screen box 2 are provided with sliding grooves 6. The bottom of the slider 5 is slidably disposed in the sliding grooves 6. Fastening bolts 11 are threadedly connected to both sides of the screen box 2. The slider 5 is fixed to the screen box 2 through the fastening bolts 11. A guide rod 7 is fixedly provided inside the slider 5. A nut block 8 is sleeved on the guide rod 7. A feed hopper 9 is fixedly inserted through the nut block 8.

[0023] The slider 5 is fixedly provided with a drive mechanism 10 for adjusting the movement of the nut block 8. Specifically, the drive mechanism 10 includes a lead screw 101, which is rotatably disposed inside the slider 5. One end of the lead screw 101 passes through the nut block 8 and is threadedly connected to the nut block 8. A rotary motor 102 is fixedly provided on one side of the slider 5. One end of the output shaft of the rotary motor 102 passes through the slider 5 and is fixed to the lead screw 101.

[0024] The screen box 2 is fixedly provided with a feed pipe 14 at the front end, and a partition 15 is fixedly provided at the top of the feed pipe 14. The partition 15 is located at the bottom of the screen 3.

[0025] Multiple evenly distributed spring-damped shock absorbers 16 are connected between the bottom of the screen box 2 and the mounting frame 1. Each spring-damped shock absorber 16 is a device used to reduce or suppress vibrations in a mechanical system. The spring in the spring-damped shock absorber 16 is elastic; when subjected to external vibration force, it deforms to absorb and store vibration energy. When the external force disappears, the spring returns to its original shape, releasing the energy. The damper inside the spring-damped shock absorber 16 is typically a liquid damper. The liquid flows slowly through the deceleration holes inside the damper, generating resistance to control the release of spring energy and prevent excessive spring rebound. Small impact force, damping force and liquid flow velocity are directly proportional. Different deceleration hole designs can produce different damping effects to adapt to vibrations of different frequencies and amplitudes. Vibration motors 17 are fixed on both sides of the bottom of the screen box 2. The vibration motor 17 is a motor device that converts electrical energy into mechanical energy and generates centrifugal force through the rotation of the eccentric block to obtain excitation force. For example, a linear vibration motor generates eccentric force through the linear motion of the motor. Vibration is achieved by changing the direction of the motor's motion. The amplitude and frequency are related to the motor's motion speed, the weight of the eccentric block and the eccentric distance between the eccentric block and the motor axis.

[0026] In actual operation, the staff first pushes the slider 5 above the screen 3 and fixes it with the fastening bolt 11. Then, the dehydrated vegetables to be screened are poured into the feed hopper 9. Two vibrating motors 17 are used to drive the screen box 2 and the screen 3 to vibrate together. The dehydrated vegetables move forward on the screen 3 while vibrating. The fragments fall into the screen box 2 through the screen 3 and are discharged through the feed pipe 14 at the front of the screen box 2. The screened dehydrated vegetables flow out from the front of the partition 15, achieving effective separation and collection. At the same time, the multiple spring damping shock absorbers 16 set between the screen box 2 and the mounting frame 1 can effectively reduce vibration. In addition, the rotary motor 102 drives the lead screw 101 to rotate back and forth. The lead screw 101 drives the nut block 8 to move back and forth along the guide rod 7, thereby evenly distributing the dehydrated vegetables on the screen 3, which helps to improve the screening effect and screening efficiency.

[0027] After use, staff can separate the connecting plate 4 from the screen box 2, and then grasp the handle on the connecting plate 4 to flip the screen 3 open, which makes it easy to clean the screen 3 and the inside of the screen box 2, greatly facilitating subsequent maintenance.

[0028] like Figure 1 As shown, a cover plate 12 is hinged to the top of the feed hopper 9, and a solenoid valve 13 is fixedly installed at the bottom of the feed hopper 9. The solenoid valve 13 is an industrial device controlled by electromagnetic force. When the electromagnetic coil is energized, the generated electromagnetic force drives the valve core to move, thereby opening or closing the fluid passage. When the power is off, the spring force or its own weight resets the valve core, completing the on / off switching, thereby controlling the fluid. The amount of dehydrated vegetables is controlled by the solenoid valve 13, thereby ensuring the normal screening operation of the screen 3. After use, the cover plate 12 is closed to prevent dust and impurities from contaminating the inside of the feed hopper 9.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
