Description

Technical Field

[0001] The utility model relates to the technical field of melon seed sorting, and more specifically, to a melon seed impurity removing and sorting screen. Background Art

[0002] Melon seeds, also known as melon seeds, are commonly known as side fruits. There are many types of melon seeds, including sunflower seeds, clams, white melon seeds, hanging melon seeds, watermelon seeds, pumpkin seeds, cucumber seeds, loofah seeds, etc. Before packing the melon seeds, it is usually necessary to sort the melon seeds, and small melon seeds and impurities can be sorted to ensure the quality of the melon seeds after packaging. At present, the melon seeds are sorted in the form of filtering with a filter net. For example, patent application number CN202022850039.6 introduces a sorting device for melon seed processing, which has a number of fixed blocks symmetrically arranged on both sides of the inner wall of the sorting box, and a slide groove is opened on the side of the fixed block away from the inner wall of the sorting box, and a sieve plate is arranged between the two groups of symmetrically arranged fixed blocks. In this way, the sieve plate can be pulled out, which is convenient for collecting melon seeds and cleaning the mesh plate, which is beneficial to improving the sieving effect. However, this flat screening method still requires personnel to pull out the sieve plate for cleaning, and still requires regular manual cleaning. Melon seeds are easily stuck in the mesh of the sieve plate. Manual cleaning is very time-consuming and requires frequent shutdowns for cleaning, which makes the sorting device less continuous and leads to low efficiency.

[0003] In response to the above problems, there is a melon seed sorting device with a publication number CN220496864U, which includes a chassis, a driving motor is fixedly installed on the side of the chassis, the output end of the driving motor is driven and connected to a central axis, a cylindrical filter is fixedly connected to the central axis, the cylindrical filter is tilted, an inlet is provided on one side of the cylindrical filter, an outlet is provided on the other side of the cylindrical filter, and a cleaning component is provided above the cylindrical filter.

[0004] The sorting device of the above scheme is configured by placing a cylindrical filter in a chassis and driving it to rotate by a driving motor. Melon seeds are put in from the entrance. This method can turn the melon seeds over, which is beneficial for filtering and sorting the melon seeds. In addition, a cleaning device is configured, and the driving motor is used to drive the roller to rotate in the opposite direction, so that the cleaning nails can push the melon seeds stuck on the mesh of the cylindrical filter, thereby playing a cleaning role.

[0005] At the same time, the utility model proposes a new solution to solve the problem that regular manual cleaning is still required, and melon seeds are easily stuck in the mesh of the sieve plate, which is very time-consuming and leads to low efficiency of the sorting device.

[0011] The utility model is further configured as follows: a slot for the push rod to move is provided on the chassis, and a protective sleeve matching the slot is provided on the outer side of the push rod.

[0012] By adopting the above technical solution, the push rod is inserted into the protective cover and the protective cover protects the push rod to prevent friction and wear between the push rod and the chassis, thereby increasing the service life of the push rod and the entire driving component.

[0013] The utility model is further configured as follows: a limiting portion is protrudingly provided on the outer side of the protective sleeve, so that the overall diameter of the protective sleeve is larger than the inner diameter of the slot.

[0014] By adopting the above technical solution, the limiting portion on the protective cover prevents the protective cover from moving along with the movement of the push rod, and at the same time limits the position of the protective cover, thereby ensuring the stability between the protective cover and the push rod.

[0016] By adopting the above technical solution, the cam can always be located in the arc groove, so that the cam is confined in the arc groove and will not fall off the push plate, thereby ensuring the normal rotation efficiency and stability of the cam during rotation, while ensuring the cleaning efficiency of the cleaning plate.

[0017] The utility model is further configured as follows: the inserting rod is configured in a conical shape.

[0018] By adopting the above technical solution, the conically arranged insertion rod can be inserted into the filter hole more smoothly, and the insertion rod will not be blocked in the filter hole. It is convenient for the insertion rod to be inserted into the filter hole and then detached from the filter sorting component, thereby improving the cleaning efficiency of the filter sorting component of the cleaning plate pair.

[0019] The utility model is further configured as follows: the filtering and sorting component comprises a plurality of filter plates arranged in an inclined manner, and the filter holes of the plurality of filter plates decrease in size from top to bottom.
