Description

A kind of grain screening and dust removal equipment with rotating cylinder continuously turning for agricultural planting

technical field

Background technique

With the deepening of the reform of my country's grain circulation system, the full opening of the grain purchase market, and the diversification of grain purchase entities, in recent years some farmers, grain depots, and grain processing enterprises have equipped themselves with grain dryers, so that they can purchase high-moisture grains in a timely manner. Drying and storage, the use of these dryers has greatly alleviated the problem that grains with high moisture content cannot be purchased and stored in time, reduced the loss of grain mildew, and improved the economic benefits of farmers and enterprises. However, the performance and quality of the dryers currently on the market still cannot meet the requirements of grain drying. Therefore, the problem of how to more effectively dry and store grain has gradually emerged. my country's rice output is about 500 billion catties, and according to the calculation of the Ministry of Agriculture, the loss of grains that cannot be dried in time in general years accounts for as much as 5% of the total harvest. After the crops are harvested, especially rice and wheat, the harvested grains are mixed with dust, weeds and shriveled grains, and the impurities need to be removed in time, so the grains need to be screened. However, the commonly used screening is through flat The straight sieve plate vibrates, so because there are more grains, some grains are squeezed together, and the turning effect is poor, which is not conducive to rapid screening, and cannot be continuously screened, which is not conducive to processing and use.

Please refer to the figure, in the embodiment of the present invention, a kind of grain screening and dedusting equipment for continuous turning of the rotating cylinder for agricultural planting includes a box body 1, a feed pipe 2, a motor 3, a blower fan 4 and a protective screen 5; the box body 1. There is a rotating drum 6 with a cylindrical structure inside. A horizontal rotating shaft 7 is fixed on the outer central axis of the rotating drum 6, and the rotating shafts 7 on both sides are located on the same straight line. One end of the rotating shaft 7 is rotatably connected to the box body through a bearing. 1 on the inner wall, the other end passes through the box body 1 through the bearing fixed on the inner wall of the box body 1, the outer end is connected with the output shaft of the motor 3, and the rotating shaft 7 is driven to rotate by the motor 3, so that the rotating cylinder 6 rotates around its central axis ; A horizontal partition 12 is fixed in the corresponding box 1 above the rotating shaft 7, and the rotating cylinder 6 passes through the partition 12, and there is a small gap between the rotating cylinder 6 and the partition 12, which does not affect the rotating cylinder 6 rotation, the partition 12 divides the inside of the box body 1 into upper and lower parts.

The two side walls of the rotating cylinder 6 are evenly provided with several inlet and outlet ports 10, and when the inlet and outlet ports 10 rotate to the top, the lower end of the inlet and outlet ports 10 is flush with the upper surface of the partition plate 12, so that the inlet and outlet ports 10 follow the When rotating, the grain on the partition 12 can be fed into the rotating cylinder 6, and the material can be continuously fed to the inside. The inlet and outlet 10 is a circular hole with a diameter of 5-10 mm, so that the grain can enter through the inlet and outlet 10. Just to the inside; the curved side wall of the rotating drum 6 is embedded with a screen 11 for screening grains, and the sundries are screened out; the outer endpoint of the discharge port 10 is flush with the inner wall of the rotating drum 6, It is convenient for the grain in the rotating drum 6 to flow out. In order to increase the time of the grain in the rotating drum 6 and improve the dispersion effect, a horizontal fixed shaft 8 is fixed on the central axis in the rotating drum 6, and a horizontal fixed shaft 8 is fixed on the side wall of the fixed shaft 8. A plurality of deceleration screens 9 along the inner diameter of the rotating cylinder 6 hold and connect grains through the deceleration screens 9 to prolong the contact time with the hot air.

The fan 4 is fixedly installed on the outer wall of the box body 1, and the outer side of the fan 4 is covered with a protective screen 5, which filters the incoming air and prevents other sundries or personnel limbs from entering the fan 4. The air outlet 22 below the partition 12 sends outside air to the bottom of the partition 12 through the outlet 22; the top of the box 1 is connected with an air outlet pipe 15, and the air outlet pipe 15 is connected with an inverted U-shaped pipe 16 , the other end of the U-shaped pipe 16 communicates with the induced draft fan 13, and the induced draft fan 13 is communicated with a dust removal box 14 to filter the dust brought out by the air.

The top of the partition 12 communicates with the inclined feed pipe 2, and the outer end of the feed pipe 2 communicates with the feed hopper, and the grain is loaded into the partition 12 through the feed pipe 2. In order to improve the internal tightness, the air flows from the The air outlet pipe 15 is discharged, and a feed valve 17 is installed on the feed pipe 2; a collecting tank 20 with the same width is fixed directly below the rotating drum 6 for collecting impurity particles and the like screened; the rotating drum 6 The left side is provided with a vertical left baffle 23, and the height of the left baffle 23 is greater than the height of the inlet and outlet 10, so that the vertical left baffle 23 can be covered on the inlet and outlet 10 when it is close to the rotary drum 6, so as to avoid Grain flows out from the inlet and outlet opening 10 on the left side of the rotating cylinder 6, and the left side of the left baffle plate 23 is connected with a horizontal screw 24 through bearing rotation, and the screw 24 is threaded with a nut 25 fixed on the outer wall of the box body 1. , the position of the left baffle 23 is changed by turning the screw 24, and a handle 26 is fixedly installed on the outer end of the screw 24, which is convenient for operation and use; Same right baffle 18, right baffle 18 is fixedly connected on the horizontal cylinder 19, pushes 18 to move left and right by cylinder 19, and the inlet and outlet 10 on the right side of rotating cylinder 6 is closed, and right baffle 18 and left baffle The lower end of 23 is all fixed with the rubber scraper 27 that contacts with casing 1 bottom, is provided with discharge port 21 directly below the discharge port 10 on the right side of rotary cylinder 6.

During use, the grain is loaded into the top of the partition 12 in the box body 1 through the feed pipe 2 from the feed hopper, and the grain on the partition 12 enters the rotary drum from the inlet and outlet 10 on the side wall of the rotary drum 6 . In the rotating cylinder 6, no grain moves in the rotating cylinder 6. Due to the setting of multiple deceleration screens 9, the incoming grain falls on the deceleration screen 9, and the upwardly flowing air blows on the grain through the deceleration screen 9. to separate the dust from the grain, the deceleration screen 9 rotates with the rotating cylinder 6, when the deceleration screen 9 rotates to the downward direction, the grain falls and falls on the bottom of the rotating cylinder 6, passing through the screen 11 from the rotating cylinder 6 Fly out, carry out grain screening, turn over in the rotating drum 6, and at the same time, the air blown in under the partition 12 is blown into the rotating drum 6 from the inlet and outlet 10 below the partition 12, and flows upward through the rotating drum 6 to make the dust Separated and discharged from the top outlet pipe 15; during the screening process, the left and right baffles are used to block the inlet and outlet 10, so that the grain is screened internally. When retrieving the material, the baffle 18 is separated by the cylinder 19, and the grain falls on the discharge. Exit through port 21. In the present invention, through the rotating drum provided, the fixed inside is turned differently, the grains are thoroughly dispersed, and they are directly in contact with the blown air, which facilitates the separation of dust and reduces the dirt and dust carried in the grains; the filtered impurities are collected in the collection tank Collecting, easy to clean; without stopping the machine, the right baffle can be opened to discharge the internal grains, and the subsequent screening is carried out. The screening continuity is strong, which improves the production and processing efficiency.
