Abstract
The utility model relates to a device for recovering grains, which comprises a barrel body formed by that the upper edges of a front wall plate and a rear wall plate are connected with both sides of an upper wall plate, and the lower incline edges of the front wall plate and the rear wall plate are connected with an incline bottom plate. An inlet and an outlet are formed at both ends of the barrel body, and the inner upper part of the barrel body is provided with an incline baffle plate. The bottom is provided with a screen which is connected with the inlet and the outlet, and one end of the incline bottom plate of the barrel body is provided with a a recovering device. The inlet is connected with an air outlet of a grain thresher, and the sundries blown out from the air outlet of a fan and grains in the sundries enter the recovering device together. The heavy grains are blocked by the incline baffle plate of the recovering device and are recovered, and the light sundries are blown out. The utility model has advantages of simple structure, easy manufacture, favorable effects of separation and recovering, etc.
Description
A kind of Device for returning unthreshed grain to the threshing device belongs to agricultural rice thresher annex.
Existing rice thresher does not have Device for returning unthreshed grain to the threshing device, has the grain of rice in the foreign material that cause the rice thresher blower fan to blow out, and causes waste.
The purpose of this utility model is to provide a kind of and is connected with the rice thresher fan outlet, blower fan can be blown out the Device for returning unthreshed grain to the threshing device that the grain of rice in the foreign material separates recovery in the process of threshing operations.
The purpose of this utility model is realized by following technical scheme: a kind of Device for returning unthreshed grain to the threshing device; it is characterized in that: it comprises that the both sides by the top of forward and backward wallboard (1), (2) and wainscot (3) join; the cylindrical shell that the following hypotenuse of forward and backward wallboard (1), (2) and inclined floor (4) join and form; the left and right side of cylindrical shell is import and export (5), (6) that communicate; top in cylindrical shell is equipped with slanting baffle (7); bottom in cylindrical shell is equipped with the sieve (8) that is connected with import and export (5), (6), is equipped with notch (9) at an end of cylindrical shell inclined floor (4).
Described slanting baffle (7) is 140 °-160 ° with the angle α of wainscot (3).
Device for returning unthreshed grain to the threshing device of the present utility model is connected with the air outlet of rice thresher blower fan; the grain of rice that has in foreign material that fan outlet blows out and the foreign material enters Device for returning unthreshed grain to the threshing device together; under the effect of blast; the slanting baffle that the heavy grain of rice is recovered device stops and falls on the sieve; and fall into inclined floor and skid off notch from the sieve cylindrical void and be recovered, light foreign material are blown.Have advantages such as simple in structure, easy manufacturing, good separating effect, the grain of rice in the foreign material is reclaimed.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
Fig. 1 is a Device for returning unthreshed grain to the threshing device structural upright schematic diagram.
With reference to Fig. 1; the both sides welding of the forward and backward wallboard (1) of Device for returning unthreshed grain to the threshing device, the top of (2) and wainscot (3); forward and backward wallboard (1), (2) bend with the available block plate of inclined floor (4); also can be with the bottom and the welding of inclined floor (4) both sides of forward and backward wallboard (1), (2), forward and backward wallboard (1), (2) surround cylindrical shell after welding with wainscot (3) and inclined floor (4).Left and right side at cylindrical shell forms two square openings (5), (6) that communicate, and square opening (5) is the import (5) of recover, and import (5) is connected with the air outlet of rice thresher blower fan, and square opening (6) is foreign material blow-off outlet (6).Top in cylindrical shell is provided with slanting baffle (7), and the angle α of slanting baffle (7) and wainscot (3) is 140 °-160 °, slanting baffle (7) be by an end of wainscot (3) cut off, the other end forms to the cylindrical shell inner bending.The grain of rice that has in foreign material that fan outlet blows out and the foreign material is stopped that by slanting baffle (7) the heavy grain of rice is recovered, and light foreign material are blown.Bottom in cylindrical shell is equipped with the sieve (8) that is connected with import and export (5), (6).In the below of import (5), the top of sieve (8) is equipped with the notch (9) of band rib, notch (9) is used for receiving the grain of rice that slides in the inclined floor (4).
Claims (2)
1, a kind of Device for returning unthreshed grain to the threshing device; it is characterized in that: it comprises that the both sides by the top of forward and backward wallboard (1), (2) and wainscot (3) join; the cylindrical shell that the following hypotenuse of forward and backward wallboard (1), (2) and inclined floor (4) join and form; the left and right side of cylindrical shell is import and export (5), (6) that communicate; top in cylindrical shell is equipped with slanting baffle (7); bottom in cylindrical shell is equipped with the sieve (8) that is connected with import and export (5), (6), is equipped with notch (9) at an end of cylindrical shell inclined floor (4).
