[0002] There is an inlet on the top of the grain storage bin, and a multi-point unloading conveyor is connected to the inlet chute. The inlet chute goes deep into the bin through the inlet. In order to prevent grain grading and reduce the intensity of flattening operations, generally one inlet is equipped with multiple inlet chutes for inlet operations.

[0003] The technical problems with the existing silo are: 1. Since the silo is located at a relatively high position on the silo roof, during the initial silo operation, the grain descends at a relatively high height and at a high speed, making it easy for the grain to break; 2. Grain at the bottom of the silo descends into the silo with uneven distribution, resulting in a high intensity of the silo leveling operation. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems existing in the prior art. At the initial stage of entering the warehouse, the warehouse chute is extended to the maximum limit, and then as the loading line rises, the warehouse chute is shortened, the structural stability is strong, and the grain breakage is reduced; in addition, a slow flow device is arranged in the chute, and a conical guide plate at the bottom helps to reduce the downward speed of the grain, increase the distribution uniformity, and reduce the grain breakage.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A telescopic chute for feeding grain into a warehouse comprises: a rectangular box and a telescopic tube, wherein the telescopic tube is fixedly mounted on the bottom of the rectangular box, a plurality of reinforcing rings are fixedly sleeved on the outer surface of the telescopic tube, and a plurality of telescopic rods are fixedly mounted on opposite surfaces of the plurality of reinforcing rings, and further comprises:

[0027] In this embodiment, the utility model is fixed to the discharge end of the plow-type discharger of a multi-point unloading conveyor. During the initial loading process, two electrically operated telescopic rods 107 are activated to extend the telescopic tube 104 to its maximum extent. Multiple reinforcement rings 105 are fixedly mounted on the outer surface of the telescopic tube 104, evenly distributed across the outer surface. Telescopic rods 106 are fixedly mounted on opposite sides of the reinforcement rings 105. These rods 106 can be adjusted as the tube 104 extends. These rods 106 and reinforcement rings 105 enhance the stability of the telescopic tube 104, preventing it from shaking during grain transport. A conical guide plate 109 is connected to the bottom of the telescopic tube 104 via a connecting rod 110, effectively guiding the conveyed grain and ensuring its even distribution within the silo. As the grain loading line continues upward, the length of the telescopic tube 104 is adjusted in real time to reduce grain breakage.

[0028] Example 2, as Figure 1-4 As shown, a curved plate 102 is installed at the lower part of the rectangular box 101, and the opening at the bottom of the curved plate 102 is connected to the discharge port 115 through the inclined plate 103; a semicircular through groove 111 is opened at the center of one side of the rectangular box 101 corresponding to the curved plate 102.

[0029] A semicircular baffle 112 is movably embedded in the semicircular through groove 111, and a limit plate 113 is fixedly installed on the outer surface of the semicircular baffle 112 near the upper end. Two limit holes 114 are provided on the outer surface of the limit plate 113; a rectangular plate 117 is fixedly installed on the upper end of one side of the rectangular box 101 near the semicircular through groove 111, and both sides of the top outer surface of the rectangular plate 117 are movably embedded with limit pins 119; a connecting plate 118 is fixedly installed on the top of the two limit pins 119, and the connecting plate 118 and the rectangular box 101 are fixedly installed on the upper end of the semicircular through groove 111. Two springs 120 are fixedly connected to the opposite sides of the plate 117, and a handle 121 is fixedly installed on the top of the connecting plate 118. Pull the handle 121 upward to snap the semicircular baffle 112 into the semicircular through groove 111, then release the handle 121, and the limit pin 119 will snap into the limit hole 114 to fix the semicircular baffle 112. If you need to remove the semicircular baffle 112, just pull the handle 121 upward to make the limit pin 119 withdraw from the limit hole 114, and then you can remove the semicircular baffle 112.

[0030] Working Principle: Activating two electric telescopic rods 107 causes the telescopic tube 104 to shorten. Multiple reinforcement rings 105 are fixedly mounted on the outer surface of the telescopic tube 104, evenly distributed across the surface. Opposite the reinforcement rings 105, telescopic rods 106 are fixedly mounted. These rods 106 adjust as the telescopic tube 104 expands and contracts. These rods 106 and reinforcement rings 105 enhance the stability of the telescopic tube 104, preventing it from shaking during grain transport. The bottom of the telescopic tube 104 is connected to a conical guide plate 109 via a connecting rod 110, which guides the transported grain evenly and reduces the intensity of the unloading operation. Furthermore, the presence of curved and inclined plates further slows the flow, reducing grain velocity and minimizing grain breakage. If the utility model is blocked, the handle 121 can be pulled upward to pull the connecting plate 118 to drive the limiting pin 119 to move out from the inside of the limiting hole 114, and the semicircular baffle 112 can be removed, so that the rectangular box 101 can be manually cleaned.
