Description

A grain cleaning device for agricultural machinery with the function of filtering and treating waste residues

Technical Field

The utility model relates to the technical field related to grain cleaning, in particular to a grain cleaning device for agricultural machinery with the function of filtering and treating waste residues.

Background Art

Corn, sesame, rice and other grains need to be screened out of impurities such as flat grains, bad grains, floating leaves, etc. before processing. The existing grain cleaning machine needs to replace screens with different apertures when in use, and cannot continuously perform screening operations between different grains, so there are certain shortcomings.

For example, a grain cleaning and desoiling and hulling blowing device with publication number CN110215960A utilizes photovoltaic panels to absorb light energy to provide a source of electricity for driving a motor. The driving motor drives a worm and a worm wheel to rotate, wherein the worm also drives a fan to rotate and blow air to facilitate winnowing of grains. The worm wheel drives a rotating wheel to rotate, and the rotating wheel drives a crushing roller to rotate through a second transmission member to crush soil blocks in the grains and discharge them through filter holes. The rotating rotating wheel utilizes a connecting rod to drive a winch bucket to swing to lift up grains and lighter impurities, and cooperates with a fan to separate grains from impurities.

The above-mentioned prior art has the following technical problems: when the existing grain cleaning device is in use, the grains in the bucket are lifted up, and if the wind force of the fan is too strong, the grains will be blown away, and because the aperture of the filter hole is single, other waste residues in the grains cannot be filtered.

Therefore, we propose a grain cleaning device with the function of filtering and treating waste residues for agricultural machinery, so as to solve the above-mentioned problems.

Utility Model Content

The utility model aims to provide a grain cleaning device for agricultural machinery with the function of filtering and treating waste residues, so as to solve the problem raised by the above-mentioned background technology that the existing grain cleaning devices on the market, when in use, the grains lifted up in the winnowing bucket may be blown away if the wind force of the fan is too strong, and other waste residues in the grains cannot be filtered due to the single aperture of the filter holes.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grain cleaning device for agricultural machinery with the function of filtering and treating waste residues, comprising a frame, a lower hopper is connected through the upper part of the frame, a motor is fixedly installed on the left outer wall of the frame, and a crushing roller is fixedly connected to the output end of the motor;

Preferably, the rotating rod is connected to the fan shaft end via a transmission belt, and two groups of cams are symmetrically arranged about the rotating rod, and the directions of the two groups of cams are opposite.

By adopting the above technical solution, after the grains after preliminary cleaning fall into the turntable, the motor drives the fan to rotate, so that the fan rotates the rotating rod through the transmission belt, and then the two sets of cams on the outer wall of the rotating rod intermittently cause the turntable to flip, thereby filtering the grains in the turntable.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Embodiment 1: Please refer to Figures 1 and 5. The utility model provides the following technical solutions. The existing grain cleaning device does not process large pieces of waste residue in advance when in use, so it is easy to cause the screen to be blocked during filtration. In order to solve this technical problem, the present embodiment discloses the following technical contents: a grain cleaning device with the function of filtering and treating waste residue for agricultural machinery, comprising a frame 1, a lower hopper 2 is connected through the top of the frame 1, and a motor 3 is fixedly installed on the left outer wall of the frame 1, and a crushing roller 4 is fixedly connected to the output end of the motor 3; the crushing roller 4 is rotatably installed on the inner wall of the frame 1, and two groups of crushing rollers 4 are symmetrically arranged about the frame 1.

Before filtering the grains, firstly, the motor 3 is powered on, and then the grains are poured into the frame 1 through the lower hopper 2, so that the two sets of crushing rollers 4 crush the large pieces of waste residue in the grains, thereby preventing the large pieces of waste residue from blocking the filter holes and reducing the filtering effect.

Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. Since fine waste residues are easily attached to the surface of grains, they need to be adsorbed by an adsorption component. As shown in Figures 1 and 3, the fan 5 is rotatably mounted on the inner wall of the frame 1, and a gathering bucket 6 is fixedly mounted on the inner wall of the frame 1, and an adsorption plate 7 is fixedly connected to the bottom of the frame 1; the gathering bucket 6 is arranged in a through inverted truncated cone shape, and an electrostatic generator is installed in the adsorption plate 7. The fan 5 is connected to the output end of the motor 3 through a transmission belt, and the lower end of the frame 1 is through-connected with the upper end of the base 8.

When the crushed waste residue falls into the truncated cone-shaped collection bucket 6, the waste residue is collected for subsequent centralized processing. When the waste residue in the collection bucket 6 falls to the bottom of the frame 1, the motor 3 rotates the fan 5 through the transmission belt, so that the fan 5 blows the fallen waste residue, so that the adsorption plate 7 adsorbs some small particles in the fallen waste residue, and performs preliminary cleaning of the grains.

Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. When filtering, the waste residue is easily mixed with the grain, so it is necessary to separate the waste residue through a separation assembly. As shown in Figures 1-4 and 6, the base 8 is fixedly connected to the lower end of the frame 1, and the collection box 9 is fixedly installed at the bottom of the base 8, and the base 8 is rotatably installed with a rotating rod 15, and the outer wall of the rotating rod 15 is nested and connected with a cam 16; the fixed block 13 is fixedly installed on the inner wall of the base 8, and the outer wall of the fixed block 13 is fixedly connected with a support rod 14, and the lower end of the fixed block 13 is rotatably installed with a turntable 10, and the bottom of the turntable 10 is fixedly installed with a first screen 11 and a second screen 12 from left to right. The rotating rod 15 is connected to the shaft end of the fan 5 through a transmission belt, and the cam 16 is symmetrically arranged with two groups about the rotating rod 15, and the directions of the two groups of cams 16 are opposite. The aperture of the first screen 11 is larger than the aperture of the second screen 12, and a knocking block is arranged at the lower end of the support rod 14. The collecting box 9 is provided with two groups of spaced-apart spaces on the left and right sides, and the two groups of spaces on the left and right sides are respectively provided corresponding to the first screen 11 and the second screen 12 .

After the grains fall into the turntable 10 after preliminary cleaning, the motor 3 drives the fan 5 to rotate so that the fan 5 rotates the rotating rod 15 through the transmission belt, and then the left and right groups of cams 16 on the outer wall of the rotating rod 15 intermittently turn the turntable 10, and then filter the grains in the turntable 10. When the turntable 10 turns over and collides with the knocking block at the lower end of the support rod 14, the knocking block causes the first screen 11 and the second screen 12 in the turntable 10 to vibrate, thereby enhancing the filtering effect. The grains are repeatedly tumbled and filtered in the turntable 10, and the filtered grains pass through the first screen 11 and fall into the space on the left side of the collecting box 9, and the waste residue passes through the second screen 12 and falls into the space on the right side of the collecting box 9, thereby completing the cleaning of the grains.

The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
