Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product processing, in particular to dust and impurity removal equipment for agricultural products. Background Art

[0002] Agricultural products are items produced in agriculture, such as rice, sorghum, peanuts, corn, wheat, and local specialties of various regions. The state stipulates that primary agricultural products refer to plants, animals and their products obtained from agricultural activities. Among agricultural products, the fruits produced need to be dusted and removed before storage to ensure that the grain can be stored for a longer time and reduce the possibility of decay. Most of the existing dust and impurity removal equipment is a vibrating screen, which uses vibration to remove dust and impurities. However, this vibration makes it difficult to control the thickness of the material. When the fruit is thick, the impurity removal effect is not ideal and there is no continuity. Therefore, a dust and impurity removal equipment for agricultural products is proposed to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a dust and impurity removal device for agricultural products, comprising:

[0004] Bottom shell;

[0005] A hopper, the hopper passing through the top of the bottom shell;

[0006] A sliding sleeve, the sliding sleeve is fixedly inserted through the side wall of the bottom shell;

[0007] A slide plate, wherein the slide plate is slidably connected to the inner wall of the sliding sleeve, and the upper surface of the slide plate is in contact with the bottom surface of the discharge port of the hopper;

[0008] A fan, the fan being arranged on a side of the outer wall of the bottom shell away from the slide plate;

[0009] A filter bag, wherein the air outlet of the filter bag is fixedly connected to the air inlet of the fan;

[0010] A connecting pipe, the air outlet of the connecting pipe is fixedly connected to the air inlet of the filter bag;

[0011] The dust collecting hood is fixed to the top of the inner cavity of the bottom shell, and the side wall is connected and fixed to the air inlet of the connecting pipe, and the dust collecting surface of the dust collecting hood is processed with a plurality of through holes.

[0012] Preferably, a plurality of the through holes are equidistantly distributed on one side of the dust collecting hood.

[0013] Preferably, a filter screen is installed inside the through hole.

[0014] Preferably, an inclined block is fixed to the bottom of the inner cavity of the bottom shell, and the slope of the inclined block faces the discharge port of the bottom shell.

[0015] Preferably, four corners of the top of the bottom shell are fixedly connected with columns, and a plurality of the columns are fixedly connected to the outer wall of the hopper.

[0016] The beneficial technical effect of the utility model is that the movable slide plate and the discharge port of the hopper can form an opening and discharge material. Since the discharge port of the hopper is rectangular, the material falls in a waterfall shape as a whole, and the fan can absorb dust impurities through the filter bag, the connecting pipe and the dust collecting hood. The fan is used to replace the original vibrating screen structure, and the filter bag can recover the dust impurities. The user can continuously add material to the hopper to achieve uninterrupted dust and impurity removal, and the clean material will be discharged at the discharge port of the bottom shell by its own gravity on the slope of the inclined block. This design enables dust impurities to be better removed, and the efficiency of continuous impurity cleaning is better, which has certain practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] The utility model proposes a dust and impurity removal device for agricultural products, comprising a bottom shell 1, a hopper 2 passing through the top of the bottom shell 1, a sliding sleeve 3 fixedly passing through the side wall of the bottom shell 1, a slide plate 4 slidably connected to the inner wall of the sliding sleeve 3, and the upper surface of the slide plate 4 is fitted to the bottom surface of the discharge port of the hopper 2. The design of the sliding sleeve 3 can make the movement of the slide plate 4 more stable, and because the discharge port of the hopper 2 is rectangular, the material falls in a waterfall shape as a whole, so that the thickness of the falling material can be controlled, the fan 5 is arranged on the side of the outer wall of the bottom shell 1 away from the sliding plate 4, the air outlet of the filter bag 6 is fixedly connected to the air inlet of the fan 5, the air outlet of the connecting pipe 7 is fixedly connected to the air inlet of the filter bag 6, the dust collecting hood 8 is fixedly connected to the top of the inner cavity of the bottom shell 1, and the side wall is connected and fixedly connected to the air inlet of the connecting pipe 7, the dust collecting surface of the dust collecting hood 8 is processed with a plurality of through holes 9, the fan 5 can absorb dust impurities through the filter bag 6, the connecting pipe 7 and the dust collecting hood 8, and the filter bag 6 can recycle the dust impurities.

[0023] Specifically, a plurality of through holes 9 are equidistantly distributed on one side of the dust collecting hood 8 , and the design purpose is to ensure that dust impurities can be uniformly absorbed into the dust collecting hood 8 .

[0024] Specifically, a filter screen 10 is installed inside the through hole 9. The design of the filter screen 10 prevents the material from being sucked into it due to excessive wind force.

[0025] Specifically, an inclined block 11 is fixed to the bottom of the inner cavity of the bottom shell 1, and the slope of the inclined block 11 faces the discharge port of the bottom shell 1. The existence of the inclined block 11 allows the material to slide directly out of the inner cavity of the bottom shell 1 for collection by its own gravity.

[0026] Specifically, four corners of the top of the bottom shell 1 are fixedly connected with columns 12, and several columns 12 are fixedly connected to the outer wall of the hopper 2. Since the hopper 2 is large at the top and small at the bottom, multiple columns 12 are added to reinforce the hopper 2.

[0027] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0028] Working principle: When using this equipment, the user can place agricultural products and fruits in the hopper 2, then start the fan 5, and slowly pull the slide plate 4 at the same time, so that the slide plate 4 and the discharge port of the hopper 2 form an opening and discharge the material. Since the discharge port of the hopper 2 is rectangular, the material falls in a waterfall shape as a whole, and the fan 5 can absorb dust impurities through the filter bag 6, the connecting pipe 7 and the dust collecting hood 8. The fan 5 is used to replace the original vibrating screen structure, and the wind force is moderate to avoid adsorbing the material on the surface of the filter screen 10, and the filter bag 6 can recover the dust impurities. The user can continuously add materials to the hopper 2 to achieve uninterrupted dust and impurity removal, and the clean material will be discharged at the discharge port of the bottom shell 1 on the slope of the inclined block 11 by its own gravity. This design allows dust impurities to be better removed and the efficiency of continuous cleaning is better.
