Since most of the existing grain elevators are inclined, the height of the upper end of the elevator is also relatively high, resulting in the center of gravity being upward. When the device is moved, when the road appears slope or windy, the risk of the elevator tipping over will be greatly increased, and the transfer is not convenient enough. Utility Model Content

DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, a grain elevator comprises a screw conveyor 1, the screw conveyor 1 comprises an outer cylinder 2, a feed hopper 3 is arranged on the outer cylinder 2, a spiral blade is arranged inside the outer cylinder 2, a motor 4 for driving the spiral blade to rotate is arranged outside the outer cylinder 2, a discharge port 5 is arranged at the upper end of the outer cylinder 2, a first mounting plate 6 is arranged at the lower end of the cylinder, universal wheels 7 are arranged at both ends of the first mounting plate 6, a second mounting plate 8 is arranged at the middle position of the cylinder, a slot is arranged on the second mounting plate 8, and a retaining frame 9 is also included. A directional wheel 10 is symmetrically arranged at one end of the retaining frame 9, and a positioning frame 11 is arranged at the other end of the retaining frame 9. The positioning frame 11 and the directional wheel 10 are respectively located on both sides of the outer cylinder 2. A connecting rod 12 is arranged at the middle position of the retaining frame 9. The retaining frame 9 is rotatably connected to the second mounting plate 8 through the connecting rod 12. A fixing frame 13 is arranged on the outer surface of the upper end of the outer cylinder 2, and also includes an electric telescopic rod 14. One end of the electric telescopic rod 14 is rotatably connected to the fixing frame 13, and the other end of the electric telescopic rod 14 is rotatably connected to the positioning frame 11.

[0019] The two universal wheels 7 on the first mounting plate 6 are used to control the moving direction of the device, and the directional wheels 10 on the retaining frame 9 facilitate pushing the device to move along a predetermined direction.

[0020] The output end of the electric telescopic rod 14 is rotatably connected to the positioning frame 11. When the output end of the electric telescopic rod 14 contracts, the retaining frame 9 can be controlled to rotate with the central axis of the connecting rod 12 as the rotation axis. When the retaining frame 9 rotates, the inclination height of the outer cylinder 2 is controlled by controlling the distance between the fixed pulley 10 and the universal wheel 7. At the same time, the center of gravity of the screw conveyor 1 is always located between the fixed pulley and the universal wheel 7 to improve the stability of the outer cylinder 2 and prevent the height of the feed hopper 3 from rising and the height of the discharge port 5 from falling. The electric telescopic rod 14 can also be replaced with a pneumatic cylinder or a hydraulic cylinder.

[0021] When the device is moved, the output end of the electric telescopic rod 14 is controlled to extend so that the retaining frame 9 rotates. When one end of the retaining frame 9 contacts the lower end surface of the fixing frame 13, the electric telescopic rod 14 stops rotating. At this time, the fixing frame 13 plays a limiting role to prevent the end of the retaining frame 9 close to the fixing frame 13 from swinging, which is beneficial to protecting the electric telescopic rod 14.

[0022] Furthermore, a top plate 15 is symmetrically provided at the lower end of the outer cylinder 2, and a reinforcing plate 16 is provided between the top plate 15 and the outer cylinder 2. When the outer cylinder 2 is tilted to a certain angle, the pressure between the universal wheel 7 and the ground can be reduced through the contact between the top plate 15 and the ground, and when moving the device, the two top plates 15 can be controlled to act as handles to push the device to move, and the reinforcing plate 16 is used to improve the stability when the top plate 15 contacts the ground.

[0023] Furthermore, an adjusting rod 17 is threadedly connected to the bottom end of the top plate 15. An external thread is provided on the outer surface of the adjusting rod 17, and a threaded hole is provided inside the top plate 15. By controlling the rotation of the adjusting rod 17, the total length of the top plate 15 and the adjusting rod 17 can be controlled. When the inclination angle of the outer cylinder body 2 is small, the top plate 15 cannot contact the ground, nor can it share the pressure for the universal wheel 7. By using the adjusting rod 17, even if the inclination angle of the adjustment cylinder is small, the top plate 15 can contact the ground through the adjusting rod 17.

[0024] Furthermore, the distance between the two directional wheels 10 is greater than the distance between the two universal wheels 7, which is beneficial to improving the overall stability of the device when the outer cylinder 2 is tilted.

[0025] Working principle: When the device is moved, the output end of the electric telescopic rod 14 is controlled to extend, driving the positioning frame 11 and the retaining frame 9 to rotate. When one end of the retaining frame 9 contacts the lower end surface of the fixing frame 13, the outer cylinder 2 is in or approximately in a horizontal state. At this time, the overall height of the device is reduced, the center of gravity of the device is lowered, and then the device can be pushed to move through the top plate 15.

[0026] When moving the device, by lowering the center of gravity of the device, the stability of the device on slopes and in windy weather outdoors can be improved, and the safety level is greatly improved. In addition, by setting the first electric telescopic rod 14, the positioning frame 11 and the retaining frame 9, the position of the outer cylinder 2 can be quickly adjusted, which is easy to use.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
