Description

Technical Field

[0001] This utility model relates to the field of rapeseed processing, and in particular to a rapeseed cleaning device. Background Technology

[0002] Rapeseed seeds, also known as rapeseed, are the seeds of the rapeseed plant, a cruciferous crop. Rapeseed is a biennial herb, 30-90 cm tall; its stems are stout, erect, branched or unbranched, glabrous or nearly glabrous, slightly powdery. Its seeds are spherical, about 1.5 mm in diameter, and purplish-brown. The oil content of rapeseed is 37.5%-46.3%, varying slightly depending on the type of rapeseed. Rapeseed is an important source of animal feed. The processing of rapeseed for oil extraction produces rapeseed meal as a byproduct. Rapeseed meal is a high-protein animal feed, mainly used for cattle, but also suitable for pigs and poultry. Furthermore, rapeseed is also an important raw material for the production of edible vegetable oil.

[0003] In the processing of rapeseed seeds, they need to be washed to remove impurities and harmful factors from the seed surface, thereby improving seed quality and germination rate. Current rapeseed washing methods mostly involve pouring the seeds into a filter bag for filtration, a process largely manual. Due to the small size of rapeseed seeds, a large number accumulate inside the filter bag during washing. When the washing water comes into contact with the seeds, the accumulated seeds cannot be fully and evenly cleaned, easily leading to incomplete washing. To improve washing efficiency, the seeds inside the filter bag need to be manually agitated, a time-consuming process prone to operational errors, and the washing quality cannot be guaranteed. Utility Model Content

[0004] To address the above problems, this application provides a rapeseed washing device.

[0005] To achieve the above objectives, this application provides the following technical solution: a rapeseed washing device, including a washing tank, a rotatable support frame inside the washing tank, and a filter bag outside the support frame that can separate rapeseed seeds from washing wastewater.

[0006] The support frame is equipped with a drive shaft that can rotate in the opposite direction to its rotation direction, and the drive shaft is equipped with multiple sets of stirring strips that are equidistantly distributed along a circular trajectory.

[0007] The support frame is equipped with a stirring rib that can rotate synchronously with it. The stirring rib is located above the stirring bar. As the support frame rotates, the stirring rib and the stirring bar rotate in opposite directions.

[0008] Furthermore, each set of stirring bars has an arched structure, and each set of stirring bars is composed of multiple arc-shaped bars symmetrically distributed from top to bottom.

[0009] Furthermore, the stirring rib has a U-shaped structure, and the arc-shaped protruding ribs of the stirring rib are all facing the drive shaft. The front and rear ends of the two transversely distributed ribs of the stirring rib are connected by multiple equally spaced dispersion strips, all of which have an arc-shaped structure.

[0010] Furthermore, each drive shaft is equipped with a driven gear that can rotate synchronously with it. The driven gear meshes with a drive gear that is distributed parallel to it. The drive gear meshes with a driven gear ring that is distributed coaxially with the support frame. The top of the support frame is connected to the driven gear ring through a follower rod. The driven gear, drive gear, and driven gear ring are all located on the same cover. The cover is equipped with a drive motor that can control the rotation of the drive gear.

[0011] Furthermore, the bottom of the cover is provided with a plurality of legs equidistantly arranged along a circumferential trajectory, the bottom ends of the plurality of legs are connected by a base, and the cleaning tub is disposed on the legs.

[0012] Furthermore, the support leg is provided with a guide rail coaxially distributed with the support frame, and the top of the support frame is provided with a support arm adapted to the guide rail. When the support frame rotates, the support arm rotates inside the guide rail.

[0013] Furthermore, the bottom of the cleaning tub is equipped with a drain pipe, through which the cleaning water falling into the cleaning tub can be discharged to the outside of the cleaning tub.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] This invention features stirring bars and agitators that can rotate in opposite directions, which can evenly stir the rapeseed seeds piled at the bottom of the filter bag, ensuring that the rapeseed seeds at the bottom receive a comprehensive and uniform cleaning operation. Simultaneously, it can fully stir the rapeseed seeds located in the upper part of the filter bag, creating gaps for the flow of cleaning water, effectively preventing the obstruction of cleaning water flow caused by a large accumulation of rapeseed seeds, and improving cleaning efficiency.

[0024] 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.

[0025] Example 1: Reference Figure 1-6 The rapeseed washing equipment shown includes a washing tank 1, a rotatable support frame 3 inside the washing tank 1, and a filter bag 2 outside the support frame 3 to separate the rapeseed from the washing wastewater. During the washing process, the rapeseed to be washed is poured into the support frame 3 and the filter bag 2, and then a certain amount of washing water is injected into the support frame 3.

[0026] To ensure that the rapeseed seeds accumulated inside the filter bag 2 are evenly contacted with the water, the support frame 3 is equipped with a drive shaft 4 that rotates in the opposite direction to its rotation. Multiple sets of stirring strips 5 are equidistantly distributed along a circular path on the drive shaft 4. During the rotation of the drive shaft 4, the stirring strips 5 evenly stir the rapeseed seeds accumulated at the bottom of the filter bag 2, ensuring a thorough and uniform cleaning of the seeds and effectively preventing incomplete cleaning caused by the rapeseed seeds accumulating at the bottom of the filter bag 2.

[0027] Furthermore, the support frame 3 is equipped with a stirring rib 33 that rotates synchronously with it. The stirring rib 33 is located above the stirring bar 5. As the support frame 3 rotates, the stirring rib 33 and the stirring bar 5 rotate in opposite directions. The reverse rotation of the stirring rib 33 can fully agitate the rapeseed seeds located in the upper part of the filter bag 2, forming gaps that allow the washing water to flow. This enables the washing water to fall quickly and contact the rapeseed seeds in the lower part of the filter bag 2, effectively avoiding the phenomenon of poor water flow caused by a large accumulation of rapeseed seeds, improving washing efficiency, and further enhancing the comprehensiveness of the washing operation.

[0028] Example 2: As Figure 3 , Figure 6 As shown, in order to ensure that each set of stirring strips 5 can make extensive contact with the rapeseed seeds during rotation, each set of stirring strips 5 in this application has an arched structure, and each set of stirring strips 5 is composed of multiple arc-shaped strips symmetrically distributed from top to bottom. When the stirring strips 5 rotate, they can fully contact the rapeseed seeds in the lower part of the filter bag 2, expanding the range of rapeseed seeds that can be turned over during the stirring process, and ensuring that the rapeseed seeds in a larger area in the lower part of the filter bag 2 can be fully cleaned.

[0029] like Figure 4 , Figure 5 As shown, the stirring rib 33 has a U-shaped structure, and the arc-shaped protruding ribs of the stirring rib 33 are all directly opposite the drive shaft 4. The front and rear ends of the two transversely distributed ribs of the stirring rib 33 are connected by multiple equally spaced dispersing strips 34, all of which have an arc-shaped structure. When the stirring rib 33 rotates in the opposite direction to the stirring strip 5, the arrangement of the dispersing strips 34 can effectively increase the number of gaps formed by the stirring rib 33 stirring the rapeseed during rotation, thereby forming multiple channels for the washing liquid to fall, so that the washing liquid can quickly contact the rapeseed in the lower part of the filter bag 2.

[0030] Specifically, in order for the drive shaft 4 and the support frame 3 to operate smoothly, such as Figure 3 , Figure 4 As shown, each drive shaft 4 is equipped with a driven gear 6 that can rotate synchronously with it. The driven gear 6 is meshed with a drive gear 7 that is distributed parallel to it. The drive gear 7 is meshed with a driven gear ring 8 that is distributed coaxially with the support frame 3. The top of the support frame 3 is connected to the driven gear ring 8 through a follower rod 31. The driven gear 6, drive gear 7 and driven gear ring 8 are all located on the same cover 10. The cover 10 is equipped with a drive motor 9 that can control the rotation of the drive gear 7.

[0031] Therefore, when the drive motor 9 is running, it can drive the drive gear 7 to rotate below the cover 10. Under the meshing force of itself and the driven gear 6 and driven gear ring 8, the driven gear 6 and driven gear ring 8 can move in opposite directions, so as to drive the drive shaft 4 and the support frame 3 in opposite directions.

[0032] like Figure 1 As shown, in order to maintain the stability of the cover 10, a plurality of support legs 11 are provided at the bottom of the cover 10, which are equidistantly arranged along a circular trajectory. The bottom ends of the plurality of support legs 11 are connected by a base 12. The cleaning tub 1 is placed on the support legs 11, which provide support force for the cleaning tub 1.

[0033] like Figure 2 As shown, the support leg 11 is provided with a guide rail 13 coaxially distributed with the support frame 3, and the top of the support frame 3 is provided with a support arm 32 adapted to the guide rail 13. When the support frame 3 rotates, the support arm 32 rotates inside the guide rail 13. The combination of the support arm 32 and the guide rail 13 has a reinforcing effect on the support frame 3 and can improve the stability of the support frame 3 during rotation.

[0034] like Figure 2 As shown, in order to allow the wastewater inside the cleaning tub 1 to be discharged smoothly, a drain pipe 14 is provided at the bottom of the cleaning tub 1. The cleaning water falling into the cleaning tub 1 can be discharged to the outside of the cleaning tub 1 through the drain pipe 14.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
