[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-7 This utility model provides a technical solution: a vacuum grain storage barrel device with angle adjustment function, including: a base 1 and a vacuum grain storage barrel body 2; a barrel cover 3 is hinged to the top of the vacuum grain storage barrel body 2, the upper end of the base 1 is open, guide grooves 4 are symmetrically arranged on the inner walls of both sides of the base 1, and pulleys 5 are symmetrically arranged on both sides of the bottom end of the vacuum grain storage barrel body 2, and the pulleys 5 are movably arranged in the guide grooves 4; the vacuum grain storage barrel body 2 is set in the base 1 through auxiliary components.

[0017] The control chamber 6 in the auxiliary component is set on the inner bottom wall of the base 1. A counterweight 7 is connected to the inner bottom wall of the base 1. An electric push rod 8 is set on the inner bottom wall of the base 1. A U-shaped bracket 9 is connected to the bottom wall of the vacuum grain storage tank 2. The end of the electric push rod 8 is rotatably connected to the U-shaped bracket 9 through a pin.

[0018] A vacuuming mechanism is installed inside the lid 3. The vacuuming mechanism includes components such as a miniature vacuum pump, air valve, solenoid valve, and air pressure sensor. The control compartment 6 includes components such as a control panel, battery, and main control board. The vacuuming mechanism and electric push rod 8 are electrically connected to the control compartment 6. The electric push rod 8 is in a vertical state. When the electric push rod 8 extends or retracts, it drives one side of the vacuum grain storage barrel 2 to rise or fall. It is movably set in the guide groove 4 with the pulley 5, so that the tilt angle of the vacuum grain storage barrel 2 can be adjusted within the base 1.

[0019] A cross groove 10 is provided on one side end wall of the base 1. A cross plate 11 is embedded in the cross groove 10. An inclined plate 12 is connected to the end wall of the cross plate 11. A damping shock absorber 13 is connected to the inclined surface of the inclined plate 12. A U-shaped plate 14 is connected to the other end of the damping shock absorber 13. A rubber roller 15 is rotatably installed in the groove of the U-shaped plate 14. The rubber roller 15 is in close contact with the vacuum grain storage barrel 2.

[0020] The cross plate 11 is embedded in the cross groove 10 for positioning and installing the damping shock absorber 13. The damping shock absorber 13 is set on the inclined surface of the inclined plate 12, so that the damping shock absorber 13 is in an inclined state, which makes it easier for the rubber roller 15 to contact the vacuum grain storage barrel 2. When the vacuum grain storage barrel 2 is tilted, the vacuum grain storage barrel 2 abuts against the rubber roller 15, and the damping shock absorber 13 assists in supporting the vacuum grain storage barrel 2 and plays a role in shock absorption.

[0021] The base 1 has symmetrically opened sliding grooves 16 on both sides of one side end wall. Two U-shaped limiting plates 17 are symmetrically snapped on one side end wall of the base 1. A slider 18 is connected to the side wall of the U-shaped limiting plate 17. The slider 18 is movably snapped in the sliding groove 16. The U-shaped limiting plate 17 is snapped with the cross plate 11.

[0022] The slider 18 is movable and snapped into the slide groove 16, so that the U-shaped limiting plate 17 can be stably and horizontally moved. It is set on one side end wall of the base 1. The inner side wall of the U-shaped limiting plate 17 is snapped into the end wall of the cross plate 11 to achieve limiting and prevent the cross plate 11 from separating from the cross groove 10.

[0023] The U-shaped limiting plate 17 has a slot 19 on its side wall, and a rotating plate 20 is rotatably mounted on the side wall of the base 1. Two locking blocks 21 are symmetrically connected to one end of the rotating plate 20, and the locking blocks 21 engage with the slot 19. A hand-tightening bolt 22 is threadedly connected to the side wall of the rotating plate 20, and a positioning hole 23 is provided on the side wall of the base 1. The screw of the hand-tightening bolt 22 is inserted into the positioning hole 23.

[0024] Rotating the rotating plate 20 controls the locking block 21 to rotate accordingly. The locking block 21 engages with the locking groove 19 to fix the position of the U-shaped limiting plate 17. The hand-tightening bolt 22 threaded on the side wall of the rotating plate 20 is inserted into the positioning hole 23 to fix the position of the rotating plate 20.

[0025] Working principle: After the U-shaped limiting plate 17 is moved to expose the cross groove 10, the cross plate 11 is fitted into the cross groove 10. Then, the U-shaped limiting plate 17 is moved in the opposite direction to limit the cross plate 11 until the slider 18 moves to the end of the slide groove 16. Then, the rotating plate 20 is rotated to fit against the side wall of the base 1. At this time, the locking block 21 rotates with the rotating plate 20 and locks into the locking groove 19, thereby fixing the position of the U-shaped limiting plate 17. Then, the hand-tightening bolt 22 is threaded to the rotating plate 20 and screwed into the positioning hole 23 to fix the position of the rotating plate 20, thus completing the installation of the damping shock absorber 13; electric When the push rod 8 extends, it lifts one side of the vacuum grain storage barrel 2. This, combined with the pulley 5 which is movably positioned within the guide groove 4, allows the vacuum grain storage barrel 2 to adjust its tilt angle within the base 1. During the tilting process, the vacuum grain storage barrel 2 rests against the rubber roller 15. As the vacuum grain storage barrel 2 continues to tilt, the rubber roller 15 rolls along the side wall of the vacuum grain storage barrel 2, simultaneously compressing the damping shock absorber 13. The damping shock absorber 13 assists in supporting the vacuum grain storage barrel 2 and provides shock absorption; this prevents users from manually removing the storage barrel from the tilted opening, making grain retrieval convenient and effortless.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
