Description

Technical Field

[0001] This utility model relates to the field of hawthorn washing and screening technology, and in particular to a hawthorn raw material washing and screening device. Background Technology

[0002] In the hawthorn processing, the first step is to screen and clean the hawthorns. In addition to impurities such as leaves and branches, the hawthorns sent to the factory by fruit farmers also contain a small amount of stone particles. The stone particles are heavy, so the wind screening cannot remove the impurities such as stones. As a result, the hawthorns still carry stones and other impurities after being cleaned by the bubble washing machine.

[0003] To address the aforementioned problems, those skilled in the art have made improvements to existing technologies. For example, a bubble cleaning machine for cleaning hawthorns, disclosed in CN220403008U, includes a cleaning tank with a mesh belt conveyor for transporting hawthorns inside. An air pump is installed outside the cleaning tank and connected to an exhaust assembly inside the cleaning tank via a pipeline. A sedimentation tank is provided on the feed side of the cleaning tank, and a hawthorn inlet is provided on the feed side. A connecting port is provided at the bottom of the feed side of the cleaning tank to connect the cleaning tank and the sedimentation tank. This device can screen out impurities such as stones from the hawthorns. However, the above device lacks a downward pressure structure for the hawthorns, so the hawthorns cannot be fully immersed in the cleaning solution during cleaning, resulting in poor cleaning effect. Furthermore, the above device relies solely on the movement of the hawthorns themselves to complete the transfer from the water tank to the mesh belt conveyor, resulting in poor transport efficiency. Some hawthorns may remain in the water tank for a long time, causing damage to the appearance of these hawthorns.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

A cross rod assembly 232 is provided between the central sliders 231 and the bottom surface of the housing 1 (that is, the top two ends of the cross rod assembly 232 are rotatably connected to the two central sliders 231 on the same central sleeve shaft 23, and the bottom two ends of the cross rod assembly 232 are rotatably connected to the two sliding plates, and the sliding plates are slidably connected to the bottom surface of the housing 1).

[0023] See Figures 1-3Side sleeve shafts 24 are rotatably mounted on the rotating shafts 22 on both sides of the central sleeve shaft 23. Each side sleeve shaft 24 has a reverse ratchet (the reverse ratchet is opposite in direction to the positive ratchet) on one end of its side wall. The reverse ratchet, side sleeve shaft 24, and rotating shaft 22 are concentric. A unidirectional rotatable reverse pawl is mounted on the rotating shaft 22. Each side sleeve shaft 24 has a side slider 27, which is slidably connected to a sliding seat 21. Each side slider 27 has a second circulation groove. The second circulation grooves on two side sleeve shafts 24 that cooperate with the same rotating shaft 22 are in opposite directions. The side sliders 27 and the second circulation grooves are matched one-to-one (the cooperation method between the side sliders 27 and the second circulation groove is the same as that between the central slider 231 and the first circulation groove). Each rotating shaft 22 is provided with a top fixed shaft 252 and a bottom fixed shaft 262 on one side near the center of the sliding seat 21. The top fixed shaft 252 is located below the bottom fixed shaft 262. A top screen plate 25 is rotatably mounted on the top fixed shaft 252. Two first connecting blocks are rotatably connected to the top fixed shaft 252 on the top screen plate 25. The two first connecting blocks on the same top screen plate 25 are respectively located at the ends of the two side sleeve shafts 24 on the same rotating shaft 22 that are far apart from each other. A bottom screen plate 26 is rotatably mounted on each bottom fixed shaft 262. Two second connecting blocks are rotatably connected to the bottom fixed shaft 262 on each bottom screen plate 26. The two second connecting blocks on the same bottom screen plate 26 are respectively located at the ends of the two side sleeve shafts 24 on the same rotating shaft 22 that are close to each other. The first connecting block is connected to a top external threaded sleeve 251 at the end near the center of the rotating shaft 22, and the second connecting block is connected to a bottom external threaded sleeve 261 at the end away from the center of the rotating shaft 22. The side slider 27 is provided with a bottom internal threaded sleeve 27 that can cooperate with the top external threaded sleeve 251 and a bottom internal threaded sleeve that can cooperate with the bottom external threaded sleeve 261.

[0024] See Figures 1-3 Preferably, torsion springs are provided at the connection between the first connecting block and the top fixed shaft 252 and at the connection between the second connecting block and the bottom fixed shaft 262. When the torsion springs are in their natural state, both the top screen plate 25 and the bottom screen plate 26 are in the open state (i.e., in the vertical state).

[0025] See Figures 1-3 Preferably, the drive component is a rotary motor that can provide sufficient power, and the drive component needs to be waterproofed.

[0026] See Figures 1-3 Preferably, both the top sieve plate 25 and the bottom sieve plate 26 are provided with a number of sieve holes.

[0027] In the implementation of this utility model: When the device is in its initial state, both the top sieve plate 25 and the bottom sieve plate 26 are in the open state. A cleaning solution and an appropriate amount of hawthorn are added to the box 1 (the hawthorn floats on top of the cleaning solution, and insoluble impurities such as stones sink to the bottom of the box 1). Then, the drive is started and reversed. At this time, the positive ratchet does not engage with the positive pawl, and the negative ratchet engages with the negative pawl. The central sleeve shaft 23 does not rotate, while the side sleeve shaft 24 rotates, driving the side slider 27 to move towards the first connecting block. The top inner threaded sleeve 271 engages with the top outer threaded sleeve 251, causing the two top sieve plates 25 to rotate to the closed state (i.e., the horizontal state). Then, the drive rotates forward, and the central sleeve shaft 23 rotates. The two central sliders 231 on the same central sleeve shaft 23 move away from each other, causing the sliding seat 1 to descend. Under the action of the top sieve plate 25, all the hawthorn floating on top of the cleaning solution is immersed in the cleaning solution. The bubble generator is turned on to clean the hawthorn.

[0028] After cleaning, the drive unit reverses, and the side slider 27 moves towards the second connecting block, so that the bottom inner threaded sleeve 272 engages with the bottom outer threaded sleeve 261, closing the two bottom screen plates 26. At this time, the top inner threaded sleeve 272 disengages from the top outer threaded sleeve 251, and the two top screen plates 25 open under the action of the torsion spring. Then the drive unit rotates forward, causing the sliding seat 21 to drive the bottom screen plates 26 to rise, thereby completely scooping out the hawthorns in the box 1.

[0029] This utility model provides a hawthorn raw material washing and screening device, which has the following beneficial effects:

[0030] 1. By setting up a cleaning component, the hawthorn can be fully immersed in the cleaning solution for a more thorough and effective cleaning, and the hawthorn can be automatically retrieved, reducing the labor intensity of users. It can also remove impurities such as stones from the hawthorn, simplifying the workflow.

[0031] 2. The device can be driven by a single drive component, which reduces manufacturing and usage costs.

[0032] In summary, the beneficial effects of this utility model are: it can effectively clean hawthorns, automatically remove hawthorns, and screen out impurities such as stones from hawthorns.

[0033] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
