Description

Technical Field

[0001] This utility model is a pumpkin seed processing and cleaning device, belonging to the field of agricultural product processing technology. Background Technology

[0002] Pumpkin seeds are rich in nutrients such as unsaturated fatty acids and protein, making them an agricultural product with both edible and seedling value. Cleaning is a crucial step in their processing—it's necessary to remove fruit pulp residue, dirt, mucus, and other impurities adhering to the seed surface to prevent mold and spoilage during subsequent storage. Existing pumpkin seed cleaning devices are mostly modifications of general seed cleaning equipment, failing to fully adapt to the characteristics of pumpkin seeds—thin skin, easily damaged, and with strong mucus adhesion—resulting in numerous technical shortcomings.

[0003] For example, Chinese patent CN222001026U proposes a pumpkin seed processing and cleaning device. This device uses a cloth-spreading mechanism to evenly distribute pumpkin seeds onto a conveyor belt. A speed-reducing motor drives the active roller to rotate, which in turn drives the conveyor belt with the driven roller, thus transporting the pumpkin seeds. A suitable amount of water is manually added to the cleaning chamber, and a water pump draws the water to a connecting pipe. Under pressure, the water is sprayed onto the pumpkin seeds on the conveyor belt using nozzles for cleaning. However, this single-spraying method can only remove surface dust from the pumpkin seeds and is insufficient to remove the pulp and mucus from the seed crevices. The cleaning effect is limited, often requiring repeated cleaning or subsequent manual assistance. Therefore, a pumpkin seed processing and cleaning device is urgently needed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pumpkin seed processing and cleaning device to solve the problems mentioned in the background. This invention adopts a flexible multi-stage cleaning structure, using a flexible silicone stirring paddle, a flexible brush disc, and a brush cleaning roller. First, large pieces of pulp are removed by stirring, and then the seed crevices are gently brushed clean by the brush cleaning roller, thus solving the defects of existing structures such as seed damage and incomplete cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pumpkin seed processing and cleaning device, comprising a support frame, a water collection tank, and a cleaning bucket. The support frame houses the water collection tank, with one-way wheels installed around its lower perimeter. An intercepting grid is secured to the upper end of the water collection tank. A soft brush housing is mounted on the upper end of the support frame. A first connecting shaft and a second connecting shaft are internally mounted within the soft brush housing via bearings.

A first spur gear is installed on the right end of the dual-output shaft motor, and a second spur gear is installed on the right end of the second connecting shaft. Both the first and second connecting shafts are fitted with brush cleaning rollers on their outer surfaces. A side plate is longitudinally fixed to the upper left side of the soft brush box. A hydraulic rod is fixed to the right end of the side plate by multiple bolts. A connecting plate is installed on the upper end of the hydraulic rod by a flange and bolts. A stirring motor is installed on the upper right side of the connecting plate by bolts. A stirring shaft is installed on the shaft end of the stirring motor. A silicone flexible stirring paddle is installed in the middle of the outside of the stirring shaft. A flexible brush disc is installed on the lower outside of the stirring shaft. Multiple brush strips are installed on the lower end of the flexible brush disc. The conical lower end of the cleaning bucket is connected to the soft brush box through a valve.

[0006] Furthermore, an inclined support plate is installed on the lower front side of the support frame.

[0007] Furthermore, a pull handle is installed at the front end of the water collection tank.

[0008] Furthermore, a feeding hopper is provided on the lower left side of the soft brush box, and the feeding hopper is located above the water collection tank.

[0009] Furthermore, the first spur gear meshes with the second spur gear.

[0010] Furthermore, a diagonal tie rod is fixed to the lower left side of the connecting plate, and the other end of the diagonal tie rod is connected to the movable end of the hydraulic rod.

[0011] Furthermore, the cleaning tub is located above the brush box, and the outlet end of the cleaning tub is located above the two brush cleaning rollers.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a pumpkin seed processing and cleaning device.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-3This utility model provides a technical solution: a pumpkin seed processing and cleaning device, including a support frame 1, a water collection tank 3, and a cleaning bucket 23. The support frame 1 is equipped with a water collection tank 3, and one-way wheels 4 are installed around the lower end of the water collection tank 3. An intercepting grid 6 is clamped at the upper end of the water collection tank 3. A soft brush box 7 is installed at the upper end of the support frame 1. A first connecting shaft 12 and a second connecting shaft 13 are installed inside the soft brush box 7 through bearings. A dual-output shaft motor 9 is installed at the right end of the soft brush box 7. The left end of the dual-output shaft motor 9 is connected to the first connecting shaft 12. A first spur gear 10 is installed at the right end of the dual-output shaft motor 9. A second spur gear 11 is installed at the right end of the second connecting shaft 13. Brush cleaning rollers 14 are sleeved on the outer surfaces of the first connecting shaft 12 and the second connecting shaft 13. A side plate 15 is longitudinally fixed on the left side of the upper end of the soft brush box 7. A hydraulic rod 16 is fixed to the right end by multiple bolts. A connecting plate 17 is installed on the upper end of the hydraulic rod 16 by a flange and bolts. A stirring motor 18 is installed on the upper right side of the connecting plate 17 by bolts. A stirring shaft 19 is installed on the shaft end of the stirring motor 18. A silicone flexible stirring paddle 20 is installed in the middle of the outside of the stirring shaft 19. A flexible brush disc 21 is installed on the lower outside of the stirring shaft 19. Multiple brush strips 22 are installed on the lower end of the flexible brush disc 21. The conical lower end of the cleaning tank 23 is connected to the soft brush box 7 through a valve 25. Multiple brush liner plates 24 are inserted into the inner side wall of the cleaning tank 23. This design solves the problem that the original pumpkin seed processing and cleaning device, which uses a single spray, can only remove floating dust on the surface of pumpkin seeds and is difficult to remove the pulp and mucus in the seed crevices. The removal effect is limited and often requires repeated cleaning or subsequent manual assistance.

[0017] As the first embodiment of this utility model: an inclined support plate 2 is installed on the lower front side of the support frame 1. The added inclined support plate 2 provides sliding support for the water collection tank 3, preventing the front end of the water collection tank 3 from drooping and getting stuck when it is pushed or pulled, and adapting to the movement trajectory of the one-way wheel 4.

[0018] A pull handle 5 is installed at the front end of the water collection tank 3. The pull handle 5 is installed at the front end of the water collection tank 3. Its function is to provide a point of force, so that the operator can easily pull the water collection tank 3 out of the support frame 1 for cleaning by pulling the handle 5 and using the one-way wheel 4 at the bottom of the water collection tank 3, or push the cleaned water collection tank 3 back to its original position, which greatly simplifies the maintenance operation.

[0019] A hopper 8 is located on the lower left side of the brush cleaning box 7, above the water collection tank 3. The hopper 8 serves as a centralized discharge channel for the washed seeds and wastewater. The mixture of seeds and water after being cleaned by the brush cleaning roller 14 is guided by the hopper 8 and falls onto the intercepting grid 6 of the water collection tank 3 below, achieving preliminary separation of solid and liquid seeds from water, as well as light and heavy impurities such as seeds and fruit pulp fragments.

[0020] The first spur gear 10 meshes with the second spur gear 11, forming a synchronous and reverse transmission mechanism. When the dual-output shaft motor 9 is running, its left end directly drives the first connecting shaft 12, while its right end drives the second connecting shaft 13 through this pair of meshing gears, causing the two brush cleaning rollers 14 to rotate synchronously and in opposite directions, thereby effectively rubbing and brushing the passing seeds.

[0021] A diagonal tie rod is fixed to the lower left side of the connecting plate 17, and the other end of the diagonal tie rod is connected to the movable end of the hydraulic rod 16. The diagonal tie rod, with one end fixed to the lower left side of the connecting plate 17 and the other end connected to the movable end of the hydraulic rod 16, forms a stable triangular support structure. When the hydraulic rod 16 extends or retracts to adjust the height of the stirring component, the diagonal tie rod can share the bending moment and vibration generated by the connecting plate 17 and its components, such as the stirring motor 18, enhancing the rigidity and stability of the entire lifting mechanism and preventing loosening or deformation at the connection points.

[0022] The washing tank 23 is positioned above the brush box 7, and its outlet is located above the two brush washing rollers 14. This positional relationship defines the material flow path. Its function is to ensure that the pumpkin seeds, after initial agitation, discharged from the bottom valve 25 of the washing tank 23, fall directly and accurately into the gap between the two opposing brush washing rollers 14, receiving the second core washing process, thus ensuring smooth and efficient process transitions.

[0023] As a second embodiment of this utility model: Push the device to the working position so that the water collection tank 3 is below the feeding hopper 8, and inject an appropriate amount of clean water into the washing tank 23. Ensure that the water collection tank 3 is placed inside the support frame 1 and the intercepting grid 6 on it is installed in place. When washing different batches or when it is necessary to adjust the stirring depth, the hydraulic rod 16 can be activated, and its movable end can extend and retract, driving the connecting plate 17 and the entire stirring components, such as the stirring motor 18 and stirring shaft 19, to rise or fall, thereby adjusting the immersion depth of the silicone flexible stirring paddle 20 and the flexible brush plate 21 in the washing tank 23 to adapt to different working conditions. Put wet pumpkin seeds with a large amount of pulp, flesh, and mucus into the washing tank 23. Start the stirring motor 18 to drive the stirring shaft 19 to rotate. The silicone flexible stirring paddle 20 and the flexible brush plate 21 with brush strips 22 mounted on the shaft rotate accordingly. Inside the washing tank 23, the silicone flexible stirring paddle 20 gently and powerfully stirs the mixture of seeds and pulp, initially breaking up and separating large pieces of pulp. Simultaneously, the flexible brush disc 21 and its brush strips 22, in conjunction with multiple brush liners 24, brush the seed surface, enhancing friction and further removing adhering sticky substances. This process is carried out while the seeds are immersed in water, washing impurities into the water. After the primary cleaning has been in progress for a period of time, the valve 25 at the conical lower end of the cleaning tank 23 is opened. The mixture of seeds and water flows out through the outlet under gravity. The mixture falls precisely between the two brush cleaning rollers 14 inside the lower flexible brush housing 7. The dual-shaft motor 9 is started, with the left end directly driving the first connecting shaft 12, and the right end driving the second connecting shaft 13 through the meshing of the first spur gear 10 and the second spur gear 11. The two connecting shafts drive the brush cleaning rollers 14, which are sleeved on their outer surfaces, to rotate synchronously and in opposite directions. As the seeds pass through the narrow gap between the two opposing rotating brush cleaning rollers 14, they are subjected to comprehensive and gentle rubbing and brushing, thoroughly removing stubborn mucus and fine impurities hidden deep within the seed crevices. The mixture of seeds and wastewater, after being thoroughly washed, is discharged from the hopper 8 at the left end of the brush box 7 and falls onto the intercepting grid 6 of the water collection tank 3 below. The mesh of the intercepting grid 6 allows washing water and fine impurities to pass through and fall to the bottom of the water collection tank, while the clean pumpkin seeds are intercepted above the grid. Heavier pulp residue may also be intercepted. Finally, the cleaned pumpkin seeds are removed from the intercepting grid 6, completing the processing. When there is a lot of wastewater in the water collection tank 3, the entire water collection tank can be pulled out from the support frame 1 by pulling the handle 5, using the one-way wheels 4 at the bottom, to empty the wastewater and clean the residual impurities on the intercepting grid 6, and then pushed back into place.
