Description

Technical Field

[0001] The utility model relates to the technical field of bulk grain silo inlet technology, in particular to a rotatable distributor for grain silo inlet. Background Art

[0002] At present, for bulk grain silo inlet, generally, a plurality of discharge chutes are connected to the discharge end of a plough-type discharger at the inlet of the silo top. The discharge chutes are arranged obliquely, and the bulk grain enters the silo through the discharge chutes. To increase the grain distribution range, generally, multiple discharge chutes are required. At present, some grain silos adopt a power-driven grain distributor for grain distribution. Its specific structure is: the chute is driven to rotate by a motor, and the chute drives one or more chutes to rotate. The chute is communicated with the chute, and the bulk grain slides through the chute to the end of the chute and is thrown out to realize power-driven grain distribution. The disadvantages of this kind of grain distributor are: it is necessary to arrange a motor on the grain distributor, which is inconvenient for maintenance, has relatively high energy consumption, and has certain requirements for the installation position of the grain distributor. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a rotatable distributor for grain silo inlet without power, which does not require arranging a motor to drive the rotation, and has uniform grain distribution, can reduce grain grading, and reduce energy consumption.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A rotatable distributor for grain silo inlet is arranged at the bottom end of the feed chute, and includes a feed pipe and a bearing connected to its top end. The outer circumference of the bearing is fixedly connected to the bottom end of the feed chute, the top end of the feed pipe is fixedly connected to the inner circumference of the bearing, a plurality of cloth pipes communicated with the feed pipe are uniformly arranged at the bottom of the feed pipe, the cloth pipes are spiral pipes, and the plurality of cloth pipes are uniformly distributed along the center of the bottom end face of the feed pipe and extend spirally downward.

[0006] Further, a flange one is arranged on the outer circumference of the bearing, and a flange two connected to the flange one is arranged at the bottom end of the feed chute.

[0007] Further, a fixing hole one is arranged on the inner circumference of the bearing, a corresponding fixing hole two is arranged at the top end of the feed pipe, and a fixing bolt is fixedly connected in the fixing hole one and the fixing hole two.

[0008] Further, an annular cavity one is arranged at the corresponding positions of the flange one and the flange two, and a sealing ring one is arranged in the annular cavity one.

[0009] Further, an annular cavity two is arranged at the corresponding positions of the outer circumference of the inner circumference of the bearing and the inner circumference of the feed pipe, and a sealing ring two is arranged in the annular cavity two.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model discloses a rotatable grain distributor for a granary inlet. It is fixed at the lower end of the feeding chute through a bearing. The distribution pipe is a spiral pipe, spiraling downward along the feeding pipe. Under the action of the self-weight of the grain and the impact of feeding, it drives the distribution pipe to rotate, realizing rotary grain distribution, increasing the grain distribution range, reducing grain grading, with low energy consumption and low cost.

[0012] 2. The feeding chute and the feeding pipe are connected through a bearing. A first flange is fixed on the outer circle of the bearing, and it is fixed to the feeding chute through the first flange. Threaded holes are provided on the inner circle, and it is communicated with the feeding pipe through fixing bolts. Moreover, sealing rings are arranged at the connection positions, with good sealing performance. Description of the Drawings

[0017] The following further describes the utility model in conjunction with the drawings and embodiments. Embodiment 1

[0018] As Figures 1-3 shown, a rotatable grain distributor for a granary inlet is arranged at the bottom end of the feeding chute 1, including a feeding pipe 2 and a bearing 3 connected to its top end. A first flange 5 is arranged on the outer circumference of the bearing 3, and a second flange 6 connected to the first flange 5 is arranged at the bottom end of the feeding chute 1. The first flange and the second flange are fixedly connected through bolts.

[0019] A plurality of first fixing holes 7 are provided on the inner circumference of the bearing 3, and corresponding second fixing holes 8 are provided at the top end of the feeding pipe 2. Fixing bolts are fixedly connected in the first fixing holes 7 and the second fixing holes 8.

[0020] A plurality of cloth pipes 4 communicating with the bottom of the feed pipe 2 are uniformly arranged at the bottom of the feed pipe 2. The cloth pipe 4 is a spiral pipe and is uniformly arranged along the central direction of the bottom end surface of the feed pipe 2. In this embodiment, the number of the cloth pipes 4 is 3. The specific arrangement method is as follows: the diameters of the three spiral pipes 4 are the same as the radius of the bottom end surface (circle) of the feed pipe 2, and their top surfaces are uniformly distributed within the bottom end surface of the feed pipe 2 (the top surfaces of the spiral pipes take the center of the circle of the bottom end surface of the feed pipe 2 and the points on the outer circumference as endpoints), and spiral downward along the feed pipe 2. The intersecting part of the top surfaces of the three spiral pipes is solid (see Figure 3 shown). Therefore, when the grain is shunted downward from the feed pipe 2 to the three spiral pipes, there is a tangential force between the feed port of the spiral pipe and the feed pipe 2.

[0021] To ensure the sealing performance, an annular cavity 9 is provided at the corresponding positions of the first flange 5 and the second flange 6 in this application, and a first sealing ring 10 is arranged in the annular cavity 9. An annular cavity 11 is arranged at the corresponding positions of the outer periphery of the inner circumference of the bearing 3 and the inner circumference of the feed pipe 2, and a second sealing ring 12 is arranged in the annular cavity 11 to ensure the sealing between the feed chute and the feed pipe 2 and prevent dust from entering the bearing 3 and affecting the service life of the connecting parts.

[0022] After the bulk grain in this application enters the feed pipe 2 through the feed chute 1, due to the tangential force between the feed port of the spiral pipe and the feed pipe 2, when the bulk grain exits through the cloth pipe 4, under the action of the self-weight of the grain and the feeding impact, it will drive the cloth pipe 4 to rotate, and realize automatic rotation and grain discharging under the action of the bearing 3, increasing the grain distribution range and the uniformity of grain distribution.

[0023] The length of the cloth pipe 4 can be extended according to the area in the bin, with strong flexibility.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
