Description

Technical Field

[0001] This utility model relates to the field of crop seed processing technology, and in particular to a gourd seed screening and cleaning device. Background Technology

[0002] Cleaning gourd seeds removes mucus and dirt from their surface, improving germination rate and subsequent growth quality. Current gourd seed cleaning and screening equipment is simple in structure, requiring multiple manual screenings, which is time-consuming, labor-intensive, and does not achieve good impurity removal results.

[0003] The utility model patent with publication number CN209772927U provides a pumpkin seed cleaning and screening device. The device uses a motor power shaft to drive a rotating shaft to rotate, which in turn drives a half gear to rotate. During the rotation of the half gear, the connecting part moves back and forth. The connecting part moves back and forth through a connecting rod, causing the crop seeds inside the filter box to be shaken back and forth. At the same time, the water spraying component sprays water onto the crop seeds in the filter box to clean the dust off the crop seeds.

[0004] The above method cannot drain the water from the cleaned gourd seeds. The remaining moisture on the gourd seeds will cause them to mold during the subsequent drying process, thus affecting the quality of the seeds. Utility Model Content

[0005] The purpose of this invention is to provide a gourd seed screening and cleaning device, which solves the problem that the gourd seeds cannot be drained after cleaning, and that the seeds have a lot of residual moisture, which will cause the seeds to mold during the subsequent drying process, thus affecting the quality of the seeds.

[0006] To achieve the above objectives, this utility model provides a gourd seed screening and cleaning device, including a cleaning box and a screening assembly; the screening assembly includes two mounting plates, a screening cylinder, multiple screens, a first spring, and a connecting frame. The screening cylinder is rotatably disposed between the two mounting plates, and the multiple screens are spaced vertically inside the screening cylinder. The mounting plates have two connection ports, which are located on the upper and lower sides of the mounting plate, respectively. The connecting frame is slidably connected to the cleaning box, and the two ends of the first spring are fixedly connected to the connecting frame and the cleaning box, respectively. One end of the connecting frame is located inside one of the connection ports.

[0007] The screening cylinder has multiple locking structures spaced apart on both sides inside. Each screen has one locking structure on each side. Each locking structure includes a second spring and a U-shaped locking frame. The two ends of the second spring are fixedly connected to the screening cylinder and the U-shaped locking frame, respectively. The U-shaped locking frame is slidably connected to the screening cylinder. The two sides of the screen are located inside the U-shaped locking frames on both sides of the screening cylinder.

[0008] The screening cylinder has two limiting brackets spaced apart on its outer side, and the mounting plate has two arc-shaped grooves spaced apart corresponding to the limiting brackets. The two limiting brackets of the screening cylinder are respectively located inside the two arc-shaped grooves of the mounting plate.

[0009] The screening assembly further includes a toggle structure, which includes a rotating shaft, an elastic telescopic rod, and a toggle block. The rotating shaft is rotatably disposed above the cleaning tank. One end of the elastic telescopic rod is fixedly connected to the rotating shaft. One end of the toggle block is fixedly connected to the screening cylinder, and the toggle block is located on the outside of the screening cylinder.

[0010] The elastic telescopic rod includes a fixed rod, a third spring, and a movable rod. One end of the fixed rod is fixedly connected to the rotating shaft, the movable rod is slidably connected to the fixed rod, and both ends of the third spring are fixedly connected to the movable rod and the fixed rod, respectively. The third spring is located inside the fixed rod.

[0011] This utility model discloses a gourd seed screening and cleaning device. When gourd seeds need to be screened and cleaned, the gourd seeds can be placed in the screening cylinder, at which time all the gourd seeds are on the uppermost screen. The screening cylinder is then completely placed into the cleaning box, and the connecting frame is inserted into the upper connecting port to fix the mounting plate. The screening cylinder is shaken left and right to clean the gourd seeds on the screen. During the cleaning process, gourd seeds with a size smaller than the screen holes will fall onto the lower screen, thus performing multiple screenings of the gourd seeds. After screening and cleaning, pull the connecting frame to retract it from the upper connecting port. Lift the mounting plate upward so that the lower connecting port is positioned at the connecting frame. Under the action of the first spring, the connecting frame extends into the lower connecting port to fix the mounting plate again. At this time, the screening cylinder is above the cleaning box, which facilitates the draining of gourd seeds. This solves the problem that if the cleaned gourd seeds cannot be drained, and there is too much residual moisture on the gourd seeds, it will cause mold to grow during the subsequent drying process, thus affecting the seed quality.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of a gourd seed screening and cleaning device according to this utility model. Figure 2 This is a cross-sectional view of the cleaning box of a gourd seed screening and cleaning device of this utility model, located at the connecting frame.

[0020] This utility model provides a gourd seed screening and cleaning device, including a cleaning box 100 and a screening assembly. The screening assembly includes two mounting plates 210, a screening cylinder 220, multiple screens 230, a first spring 240, a connecting frame 250, a locking structure, and a toggle structure. The locking structure includes a second spring 261 and a U-shaped locking frame 262. The toggle structure includes a rotating shaft 271, an elastic telescopic rod, and a toggle block 272. The elastic telescopic rod includes a fixed rod 273, a third spring 274, and a movable rod 275.

[0021] In this specific embodiment, the screening cylinder 220 is rotatably disposed between the two mounting plates 210, and a plurality of screens 230 are vertically spaced inside the screening cylinder 220. The mounting plate 210 has two connection ports 211, located on the upper and lower sides of its side. The connecting frame 250 is slidably connected to the washing tank 100. The two ends of the first spring 240 are fixedly connected to the connecting frame 250 and the washing tank 100, respectively, with one end of the connecting frame 250 located inside one of the connection ports 211. The two mounting plates 210 are disposed on both sides of the screening cylinder 220, allowing the screening cylinder 220 to rotate relative to the mounting plates 210. The plurality of screens 230 are spaced apart inside the screening cylinder 220, with the mesh size of the screens 230 decreasing sequentially from top to bottom to sequentially screen the gourd seeds by size. When the first spring 240 is in its natural state without external force, one end of the connecting frame 250 is inside one of the connecting ports 211, thereby fixing the mounting plate 210. When it is necessary to screen and clean the gourd seeds, the gourd seeds can be placed in the screening cylinder 220, at which point all the gourd seeds are on the uppermost screen 230. The screening cylinder 220 is then completely placed into the cleaning box 100, and the connecting frame 250 is inserted into the upper connecting port 211 to fix the mounting plate 210. The screening cylinder 220 is then shaken left and right to clean the gourd seeds on the screen 230. During cleaning, gourd seeds smaller than the sieve holes of the screen 230 will fall onto the lower screen 230, thus performing multiple screenings of the gourd seeds. After screening and cleaning, pull the connecting frame 250 to retract it from the upper connecting port 211. Lift the mounting plate 210 upward so that the lower connecting port 211 is positioned at the connecting frame 250. Under the action of the first spring, the connecting frame 250 extends into the lower connecting port 211 to fix the mounting plate 210 again. At this time, the screening cylinder 220 is above the washing box 100, which facilitates the draining of gourd seeds. This solves the problem that if the washed gourd seeds cannot be drained, and there is too much residual moisture on the gourd seeds, the seeds will become moldy during the subsequent drying process, thus affecting the seed quality.

[0022] Furthermore, multiple engaging structures are spaced apart on both sides of the interior of the screening cylinder 220. Each screen 230 has one engaging structure on each side. The two ends of the second spring 261 are fixedly connected to the screening cylinder 220 and the U-shaped engaging frame 262, respectively. The U-shaped engaging frame 262 is slidably connected to the screening cylinder 220. The two sides of the screen 230 are located inside the U-shaped engaging frames 262 on both sides of the screening cylinder 220. The engaging structures are used to fix the screen 230, and the second spring 261 abuts against the U-shaped engaging frame 262. Two U-shaped engaging frames 262 cooperate to fix the screen 230 between the two U-shaped engaging frames 262.

[0023] Specifically, the outer side of the screening cylinder 220 is provided with two limiting brackets 221 at intervals, and the mounting plate 210 is provided with two arc-shaped grooves 212 at intervals corresponding to the limiting brackets 221. The two limiting brackets 221 of the screening cylinder 220 are respectively located inside the two arc-shaped grooves 212 of the mounting plate 210. The limiting brackets 221 can slide inside the arc-shaped grooves 212, and the limiting brackets 221 and the arc-shaped grooves 212 cooperate with each other to realize the rotational connection between the screening cylinder 220 and the mounting plate 210.

[0024] The rotating shaft 271 is rotatably mounted above the washing tank 100. One end of the elastic telescopic rod is fixedly connected to the rotating shaft 271, and one end of the actuating block 272 is fixedly connected to the screening cylinder 220. The actuating block 272 is located outside the screening cylinder 220. One end of the fixed rod 273 is fixedly connected to the rotating shaft 271, and the movable rod 275 is slidably connected to the fixed rod 273. Both ends of the third spring 274 are fixedly connected to the movable rod 275 and the fixed rod 273, respectively, and the third spring 274 is located inside the fixed rod 273. The actuating structure is used to drive the screening cylinder 220 to swing back and forth. The rotating shaft 271 can rotate back and forth under the drive of the rotary cylinder. The rotating shaft 271 rotates downward under the action of the rotary cylinder. When the rotating shaft 271 rotates, it can drive the telescopic rod to rotate together. When the movable rod 275 of the telescopic rod rotates to contact the actuating block 272, the movable rod 275 will drive the actuating block 272 to rotate, thereby causing the screening cylinder 220 to rotate downward. When the limiting bracket 221 of the screening cylinder 220 moves to the limit of the arc groove 212, the screening cylinder 220 can no longer rotate downwards. At this time, the movable rod 275 will move into the interior of the fixed rod 273 under the pressure of the actuating block 272, causing the third spring 274 to be compressed until the movable rod 275 is no longer supported by the actuating block 272. The movable rod 275 rotates to the lower position of the actuating block 272 as the rotating shaft 271 continues to rotate. At this time, the movable rod 275 moves out of the fixed rod 273 under the action of the third spring 274; then the rotating shaft 271 rotates under the action of the rotary cylinder. When the movable rod 275 of the telescopic rod rotates to contact the actuating block 272, the movable rod 275 will drive the actuating block 272 to rotate, thereby causing the screening cylinder 220 to rotate upward. When the limiting bracket 221 of the screening cylinder 220 moves to the limit of the arc groove 212, at this time... When the screening cylinder 220 can no longer rotate upward, the movable rod 275 will move into the interior of the fixed rod 273 under the pressure of the actuating block 272, causing the third spring 274 to be compressed until the movable rod 275 is no longer supported by the actuating block 272. The movable rod 275 will then rotate above the actuating block 272 as the rotating shaft 271 continues to rotate. This process is repeated to drive the screening cylinder 220 to sway left and right, thereby screening and cleaning the gourd seeds.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
