Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, in particular to a screening device for processing pumpkin seeds which is convenient for adjusting the angle. Background Art

[0002] With the continuous development of the food industry, pumpkin seeds, as a popular snack food raw material, have increasingly higher processing scale and quality requirements. Pumpkin seeds are often mixed with various impurities after harvest, including soil, stones, shriveled pumpkin seeds and other plant residues. Traditional processing methods are difficult to meet large-scale, high-precision screening needs. More efficient and accurate screening devices are needed to ensure the quality of pumpkin seed processing products. At present, many screening devices have fixed angles. This fixed angle design has poor adaptability when facing pumpkin seeds of different varieties and harvested from different growth environments. Therefore, a pumpkin seed processing screening device that is easy to adjust the angle is needed to screen the pumpkin seeds.

[0003] However, the existing pumpkin seed processing screening device that is easy to adjust the angle is not convenient for adjusting the angles of multiple filters at the same time during use, resulting in more time being required to find the best working angle for each filter, thereby extending the production cycle. Utility Model Content

[0004] The utility model aims to provide a screening device for pumpkin seed processing which is easy to adjust the angle. By setting an adjustment mechanism, the utility model solves the problem that the existing screening device for pumpkin seed processing which is easy to adjust the angle is not convenient for adjusting the angles of multiple filters at the same time during use, resulting in more time being required to find the best working angle for each filter, thereby prolonging the production cycle.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a screening device for pumpkin seed processing which is convenient for adjusting the angle, comprising a rectangular bottom plate, on which an adjustment mechanism and a self-locking mechanism are arranged;

[0007] Two rectangular support plates are arranged above the rectangular bottom plate, two screening plates are hingedly arranged between the two rectangular support plates, two rectangular support plates are fixedly connected to the sides away from each other, several rectangular support plates two are fixedly connected to the bottoms of spring one, several bottoms of spring one are fixedly connected to the rectangular bottom plate, a vibration motor is fixedly connected between the two rectangular support plates, the adjustment mechanism includes an adjustment component one and an adjustment component two, and the adjustment component one includes trapezoidal slide grooves respectively opened on the sides of the two rectangular support plates close to each other.

[0008] Furthermore, the inner walls of the two trapezoidal slide grooves are slidably connected with trapezoidal sliding blocks, and the sides of the two trapezoidal sliding blocks close to each other are fixedly connected with connecting blocks 1.

[0009] Furthermore, the tops and bottoms of the two connecting blocks 1 are hingedly provided with connecting rods, the sides of the two screening plates close to each other are fixedly connected to two connecting blocks 2, the sides of several connecting blocks 2 close to each other are respectively hinged to several connecting rods, and the right sides of the two adjusting component 2 connecting blocks 1 are fixedly connected to racks.

[0010] Furthermore, the second adjustment component includes a rotating shaft rotatably connected between two rectangular support plates, the front side of the rotating shaft rotates through the front rectangular support plate and extends to the outside, and two gears are fixedly connected to the outer wall of the rotating shaft, and the two gears are respectively meshed with two racks.

[0011] Furthermore, a ratchet is fixedly connected to the outer wall of the rotating shaft, and a handle is fixedly connected to the front extension portion of the rotating shaft.

[0012] Furthermore, the self-locking mechanism includes a second rotating shaft rotatably connected to the front side of the front rectangular support plate, and a clamping block is rotatably connected to the outer wall of the second rotating shaft, and the clamping block is adapted to the ratchet.

[0013] Furthermore, a spring is fixedly connected to the bottom of the block, a rectangular support plate three is fixedly connected to the front side of the rectangular support plate located on the front side, and the bottom of the spring is fixedly connected to the rectangular support plate three.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting an adjustment mechanism, if the angle of the two screening plates needs to be increased, the handle is turned according to the demand, and the handle drives the two gears to rotate at the same time through the rotating shaft. When the gears rotate, the connecting block 1 will be driven to move to the right through the rack. When the connecting block 1 moves to the right, the two screening plates will change their angles at the same time under the connection of the connecting rod and the connecting block 2, thereby completing the adjustment of the angles of the two screening plates at the same time. When the angle increases, the pumpkin seeds can be transferred from the upper screening plate to the lower screening plate more smoothly under the action of gravity, reducing the accumulation and blockage between the screening plates, ensuring that the pumpkin seeds can quickly pass through different levels of screening, thereby improving the speed of the entire screening process, and adjusting the two screening plates at the same time also greatly reduces the difficulty of operation and reduces the time spent on adjustment;

[0016] 2. By setting a self-locking mechanism, after the adjustment is completed, the card block will lock the ratchet under the action of the spring, thereby completing the locking of the rotating shaft. When the inclination angle of the screening plate needs to be lowered, the left side of the card block can be pressed, and the card block will rotate around the rotating shaft at a small angle. At this time, the spring will be compressed under the action of the rectangular support plate three. At this time, turn the handle to reduce the angle between the two screening plates. After completing the angle adjustment of the two screening plates, you can release the card block. At this time, the card block will cooperate with the ratchet under the action of the elastic force of the spring to re-lock the rotating shaft, so that the angle of the screening plate can be effectively prevented from changing accidentally due to external factors such as equipment vibration and material impact, ensuring that the screening process can be carried out stably at the set angle.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The joint mechanism 2 includes an adjustment component 1 21 and an adjustment component 2 22. The adjustment component 1 21 includes a trapezoidal slide 211 respectively opened on the side of the two rectangular support plates 101 close to each other. The inner walls of the two trapezoidal slides 211 are slidably connected with trapezoidal sliders 212. The two trapezoidal sliders 212 are fixedly connected with a connecting block 1 213 on the side close to each other. The tops and bottoms of the two connecting blocks 1 213 are hingedly provided with connecting rods 214. The two screening plates 102 are fixedly connected with two connecting blocks 215 on the side close to each other. The sides of the connecting blocks 215 close to each other are respectively hinged with the connecting rods 214. The two adjustment components 22 The right side of the connecting block 1 213 is fixedly connected with a rack 216, and the adjusting component 22 includes a rotating shaft 221 rotatably connected between the two rectangular support plates 101. The front side of the rotating shaft 221 rotates through the front rectangular support plate 101 and extends to the outside.

A ratchet 223 is fixedly connected to the outer wall of the rotating shaft 221, and a handle 224 is fixedly connected to the front extension part of the rotating shaft 221. By setting the adjusting mechanism 2, when the angle increases, the pumpkin seeds can be more smoothly transferred from the upper screening plate 102 to the lower screening plate 102 under the action of gravity, reducing the accumulation and blockage between the screening plates 102, ensuring that the pumpkin seeds can quickly pass through different levels of screening, thereby improving the speed of the entire screening process, and adjusting the two screening plates 102 at the same time also greatly reduces the difficulty of operation and reduces the time spent on adjustment.

[0029] A specific application of this embodiment is: when in use, first place the device in the corresponding position. If it is necessary to increase the angle of the two screening plates 102, turn the handle 224 as needed. The handle 224 drives the two gears 222 to rotate at the same time through the rotating shaft 221.

When the connecting block 1 213 moves to the right, the two screening plates 102 will change their angles at the same time under the connection of the connecting rod 214 and the connecting block 2 215, thereby completing the adjustment of the angles of the two screening plates 102 at the same time. When the angle increases, the pumpkin seeds can be more smoothly transferred from the upper screening plate 102 to the lower screening plate 102 under the action of gravity, reducing the accumulation and blockage between the screening plates 102, ensuring that the pumpkin seeds can quickly pass through different levels of screening, thereby improving the speed of the entire screening process. In addition, adjusting the two screening plates 102 at the same time also greatly reduces the difficulty of operation and reduces the time spent on adjustment. After the adjustment is completed, the block 302 will be under the action of the spring 303. The ratchet wheel 223 is clamped by the handle to lock the rotating shaft 221. When the inclination angle of the screening plate 102 needs to be lowered, the left side of the clamping block 302 can be pressed, and the clamping block 302 will rotate around the rotating shaft 2 301 at a small angle. At this time, the spring 303 will be compressed under the action of the rectangular support plate 304. At this time, the handle 224 is turned to reduce the angle between the two screening plates 102. After the angle adjustment of the two screening plates 102 is completed, the clamping block 302 can be released. At this time, the clamping block 302 will be elastically released by the spring 303. Under the action of force, it cooperates with the ratchet 223 to re-lock the rotating shaft 221, so that the angle of the screening plate 102 can be effectively prevented from being accidentally changed due to external factors such as equipment vibration and material impact, ensuring that the screening process can be carried out stably at the set angle. After the adjustment is completed, the pumpkin seeds to be screened can be poured onto the screening plate 102 located above, and then the vibration motor 105 is started. The vibration motor 105 drives the device to vibrate under the action of the spring 104 to complete the vibration screening of the pumpkin seeds.
