[0020] Refer to Figure 1 , this embodiment provides a device for recovering leaked grain at the rear end of an electric gate for a granary, which is mainly composed of an electric gate 1, a hopper 2, an upper joint pipe 4, a connecting pipe 5 and a lower joint pipe 6. The electric gate 1 is mainly composed of a front housing 101, a rear housing 102, a plug plate 103, a lead screw nut 104, a lead screw 105, a roller 106 and a drive mechanism 107. A plug plate hole is provided in the wall plate between the front housing 101 and the rear housing 102, and wool felt is installed around the plug plate hole. A scraper conveyor 8 is installed on the upper part of the front housing 101, and a chute pipe 7 is installed at the bottom of the front housing 101 through a flange, and the lower end of the chute pipe 7 is communicated with the storage bin.

[0021] A lead screw 105 is rotatably installed inside the rear housing 102. The lead screw nut 104 is engaged with the lead screw 105. The insertion plate 103 is horizontally installed on the lead screw nut 104 and penetrates through the insertion plate hole. Rollers 106 for supporting the insertion plate 103 are installed on both sides inside the front housing 101 and the rear housing 102. The lead screw 105 is driven by a driving mechanism 107. The driving mechanism 107 adopts a reduction motor. The reduction motor drives the lead screw 105 to rotate. The lead screw nut 104 makes a reciprocating axial movement on the lead screw 105. The lead screw nut 104 drives the insertion plate 103 to expand and contract between the front housing 101 and the rear housing 102. The insertion plate 103 opens and closes the front housing 101.

[0022] The bottom of the front housing 101 of the electric gate 1 is open and is equipped with a hopper 2. The hopper 2 is conical and is a steel plate welded structure. The upper end of the hopper 2 is rectangular or square, and the lower end of the hopper 2 is rectangular, square or circular. The upper end of the hopper 2 is connected to the front housing 101 through a flange and bolts. The hopper 2 and the front housing 101 are detachably connected, which is convenient for on-site maintenance and repair. A sealing gasket is installed between the hopper 2 and the front housing 101 to prevent material leakage.

[0023] A transition plate 3 is welded to the bottom of the hopper 2. The transition plate 3 is provided with a round hole, and the diameter of the round hole is 108 millimeters. A upper joint pipe 4 is welded to the bottom surface of the transition plate 3. The upper joint pipe 4 is a straight pipe section. The outer diameter of the upper joint pipe 4 is 108 millimeters. The upper joint pipe 4 is made of seamless pipe, and its wall thickness is 2 millimeters. The upper joint pipe 4 communicates with the round hole of the transition plate 3. A connecting pipe 5 is installed at the lower port of the upper joint pipe 4. The connecting pipe 5 is a PVC flexible pipe. The upper end of the connecting pipe 5 is sleeved on the upper joint pipe 4 and is locked by a clamp. The lower end of the connecting pipe 5 is sleeved on a lower joint pipe 6. The connecting pipe 5 and the lower joint pipe 6 are locked by a clamp. The lower joint pipe 6 is made of seamless steel pipe with an outer diameter of 108 millimeters. The lower joint pipe 6 is welded and communicated with a chute pipe 7. The lower joint pipe 6 is arranged obliquely, and the included angle range between the axis of the lower joint pipe 6 and the axis of the chute pipe 8 is 20 - 45 degrees.

[0024] After the material runs out from the insertion plate hole of the electric gate 1, it enters the rear housing 102 of the electric gate, and successively passes through the hopper 2, the upper joint pipe 4, the connecting pipe 5 and the lower joint pipe 6 to enter the chute pipe 7, and finally enters the silo. The utility model solves the problem that the material runs out from the rear end of the gate, causing material waste, and can collect the running-out material again and send it back to the chute pipe 7, saving materials and reducing costs.
