Abstract
Description
Technical Field
[0001] This utility model relates to the field of suction separator technology, specifically a chute-type suction separator. Background Technology
[0002] In the grain storage and processing industry, grains contain impurities that need to be cleaned. Some of these impurities are light impurities, such as dust, plant stalks, seed coats, hair, and weeds. These light impurities are less dense than the grains and can be separated from them using a suction method.
[0003] Application number CN202020620782.X discloses a chute-type suction separator. Several louvers are installed below the feed inlet, each louver parallel to the others and evenly arranged. Their inclination direction is the same as the material flow direction. The upper part of the vertical suction outlet section is connected to a dust collector. When the dust collector is working, air is blown into the inclined inlet section from between adjacent louvers, resulting in uniform airflow. The air flows from one side, easily carrying away impurities from the grain without requiring high wind speeds; its airflow is low, and its power consumption is low. However, in practical use, although the multiple louvers ensure uniform airflow, it is still difficult to blow out grain husks and other impurities trapped by the grain, resulting in poor cleaning effect. Utility Model Content

The separation mechanism includes a separator body, a washboard connected to the bottom of the inner cavity of the separator body, and an air inlet pipe extending through the top of the separator body. The miscellaneous separation mechanism includes a movable tube movably connected to the top of the inner cavity of the separator body, a flexible hose connected between the air inlet pipe and the movable tube, a toothed ring sleeved on one end of the movable tube, a toothed plate meshing with the toothed ring, and a cylinder connected between the separator body and the toothed plate.
[0007] By adopting the above technical solution, the moving end of the cylinder moves up and down with the toothed plate, causing the moving tube with the toothed ring to swing, increasing the blowing area of the air outlet pipe at the bottom of the moving tube. Then, the air inlet pipe injects air into the separator body and the hose.

[0010] In a preferred embodiment, the present invention can be further configured such that: the partition plate is composed of a rectangular plate and a trapezoidal plate, the rectangular plate is located inside the feed channel, the trapezoidal plate is located inside the separator body, and the partition plate is suspended above the rubbing plate and is inclined.
[0011] In a preferred embodiment, the present invention can be further configured such that the rectangular plate divides the inside of the feeding channel into an upper channel and a lower channel.
[0012] In a preferred embodiment, the present invention can be further configured such that: a bag opening support sleeve is installed at the top of the feeding channel, the thickness of the bag opening support sleeve is less than the thickness of the feeding channel, and the bag opening support sleeve is connected to the interior of the upper channel.
[0013] In a preferred embodiment, the present invention can be further configured such that: the bottom end of the separator body is connected to and communicates with a discharge channel, the height of which is half the height of the separator body.
[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0015] 1. In this utility model, the moving end of the cylinder moves up and down with the toothed plate, causing the moving tube with the toothed ring to swing, increasing the blowing area of the air outlet pipe at the bottom of the moving tube. Then, the air inlet pipe injects air into the separator body and the hose. The air flowing out from the bottom of the air inlet pipe surges upward, preventing the rice husks and other debris from continuing to slide down. Then, the moving tube, which is filled with air by the hose, blows the air through the air outlet pipe to the top of the washboard, causing the rice husks and other debris to fly away. Finally, the air is discharged from the separator body through the upper channel, resulting in a good cleaning effect.
[0016] 2. In this utility model, grains are fed into the separator body through the lower channel, and then the washboard separates the raw materials layer by layer, reducing the probability of the grains pressing down on the husks and other impurities, making the impurity removal operation easier.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.
[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a chute-type suction separator.
[0031] Example 1:
[0032] Combination Figure 1-5 As shown, the present invention provides a duct-type air intake separator, including a separation mechanism 100 and a miscellaneous separation mechanism 200. The separation mechanism 100 includes a separator body 110, a washboard 120 connected to the bottom of the inner cavity of the separator body 110, and an air inlet pipe 130 passing through the top of the separator body 110.
[0033] The separation mechanism 200 includes a movable tube 210 movably connected to the top of the inner cavity of the separator body 110, a flexible hose 220 connected between the air inlet pipe 130 and the movable tube 210, a toothed ring 230 sleeved on one end of the movable tube 210, a toothed plate 240 meshing with the toothed ring 230, and a cylinder 250 connected between the separator body 110 and the toothed plate 240.
[0034] Furthermore, the bottom end of the movable tube 210 is integrally formed with multiple air outlet pipes, which are equally spaced and arranged in a row. The air outlet pipes are connected to the interior of the movable tube 210. By setting multiple air outlet pipes, the grains on the top of the washboard 120 can be blown in a targeted manner, so that the husks pressed down by the grains can be blown away.
[0035] Furthermore, the bottom end of the separator body 110 is connected to and communicates with a discharge channel 500. The height of the discharge channel 500 is half the height of the separator body 110. The discharge channel 500 can guide the grain flowing out from the bottom end of the separator body 110 in a unified manner, thereby improving the comfort of using the device.
[0036] Example 2:
[0037] Combination Figure 1 , 3 and Figure 5 As shown, based on Embodiment 1, the separator body 110 is provided with a separating mechanism 300 at its top. The separating mechanism 300 includes a feed channel 310 connected to and communicating with the top of the separator body 110, and a partition plate 320 connected between the separator body 110 and the feed channel 310. The partition plate 320 can separate the feeding and impurity removal operations, making the device work more stably.
[0038] Furthermore, the partition plate 320 is composed of rectangular plates and trapezoidal plates. The rectangular plates are located inside the feed channel 310, and the trapezoidal plates are located inside the separator body 110. The partition plate 320 is suspended above the washboard 120 and is set at an angle. The layout design of the trapezoidal plates can guide the upward airflow in the separator body 110, so that the airflow can flow out completely from the upper channel, avoiding secondary mixing of the cleaned debris with the grains in the lower channel.
[0039] Example 3:
[0040] Combination Figure 1 and Figure 5 As shown, in the above embodiment, the rectangular plate divides the inside of the feeding channel 310 into an upper channel and a lower channel. This structural design effectively distinguishes between feeding and cleaning operations, improving the overall rationality of the device.
[0041] Furthermore, a bag mouth support sleeve 400 is installed at the top of the feeding channel 310. The thickness of the bag mouth support sleeve 400 is less than the thickness of the feeding channel 310. The bag mouth support sleeve 400 is connected to the interior of the upper channel. The bag mouth support sleeve 400 can support the bag used to collect rice husks and other debris, preventing the rice husks and other debris from flying around.
[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, grains are fed into the separator body 110 through the lower channel. Then, the rubbing plate 120 separates the raw materials layer by layer, reducing the probability of the grains pressing down on the husks and other impurities. At the same time, the cylinder 250 is activated, and the moving end of the cylinder 250 moves up and down with the toothed plate 240, causing the movable tube 210 with the toothed ring 230 to swing, increasing the blowing area of the air outlet pipe at the bottom of the movable tube 210. Then, the air inlet pipe 130 injects air into the separator body 110 and the hose 220. The air flowing out from the bottom of the air inlet pipe 130 surges upward, preventing the husks and other impurities from continuing to slide down. Then, the movable tube 210, which is filled with air by the hose 220, blows the air out through the air outlet pipe to the top of the rubbing plate 120, causing the husks and other impurities to fly away. Finally, the air is discharged from the separator body 110 through the upper channel, resulting in a good cleaning effect.
[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
