[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Figure 1-4 An open granary is shown, in which Figure 2-4The tarpaulin 4 is not provided, and the silo box 10 includes a silo box 10 with an opening upwardly and a silo door component and a power component respectively connected to the silo box 10, and the opening is rectangular. The silo box 10 can be integrated on a vehicle for movement.

[0039] The granary door component includes a pair of first doors 2 and a pair of second doors 3 arranged opposite to each other in a rectangular shape and arranged in the circumference of the opening, and the first door 2 and the second door 3 are arranged at intervals. The bottom edges of the first door 2 and the second door 3 are rotatably connected to the granary box 10, and the rotation axes are respectively parallel to the edges of the corresponding opening. The length directions of the first door 2 and the second door 3 are arranged along the four sides of the opening.

[0040] The granary door component also includes tarpaulins 4 arranged at the four corners of the opening, and the tarpaulins 4 are fixedly connected and clamped between the first door 2 and the second door 3 on the two sides of the right angle forming the opening. The material of the tarpaulin 4 is not required, and it can be flexible and deformable to achieve folding or unfolding. It is preferably made of rubber material, which is resistant to damage, waterproof, and not easy to collect dust.

[0041] When the power component drives the first door 2, the second door 3 and the tarpaulin 4 to unfold toward the outside of the opening, the first door 2, the second door 3 and the tarpaulin 4 together form a thick upper and thin lower funnel connected to the opening. That is, the first door 2, the second door 3 and the tarpaulin 4 are inclined upward and toward the outside of the granary box 10.

[0042] When the power component drives the first door 2, the second door 3 and the tarpaulin 4 to rotate toward the inside of the opening, the two first doors 2 close the opening, and the two second doors 3 are stored in the granary box 10. The rotation angle of the second door 3 is not required and does not affect the closing of the opening by the first door 2. Under the rotation of the first door 2 and the second door 3, the tarpaulin 4 is compressed downward by the two first doors 2. The tarpaulin 4 can be stored in the granary box 10.

[0043] It should be noted that it is not required that the power component drives the first door 2 and the second door 3 to be simultaneously unfolded and simultaneously rotated toward the inside of the opening. There is no requirement for the order of the rotation of the first door 2 and the second door 3. The unfolding angles of the first door 2 and the second door 3 and the rotation angles toward the inside of the opening are not required to be consistent. However, it is preferred that the second door 3 is rotated toward the inside first.

[0044] Specifically, the power component includes a first rotating component for driving the two first doors 2 to rotate, and a second rotating component for driving the two second doors 3 to rotate. The first rotating component and the second rotating component can be two hydraulic cylinders installed on the granary box 10, respectively.

[0045] The first rotating part and the second rotating part are prior art, which can be found in the Chinese utility model patent with application number CN202123372545.X and application name "A top opening and closing carriage". Or the Chinese utility model patent with application number CN202210167913.7 and application name "Wing opening and closing box structure".

[0046] The structure of the second rotating component is preferably as follows: the second rotating component includes a cylinder 31, a crank 32, a symmetrical driving shaft 33 and a driven shaft 34, a pair of fixed arms 35, a pair of rotating arms 36 and a synchronization mechanism;

[0047] The synchronizing mechanism drives the driving shaft 33 and the driven shaft 34 to rotate in opposite directions; the driving shaft 33 and the driven shaft 34 have the same structure, and the driving shaft 33 transmits the rotational power to the driven shaft 34 through the synchronizing mechanism. One of the driving shaft 33 and the driven shaft 34 rotates counterclockwise, and the other rotates clockwise, so that the two second doors rotate symmetrically. The synchronizing mechanism can be two motors that drive the driving shaft 33 and the driven shaft 34 to move in opposite directions respectively. However, the motors are required to rotate synchronously in opposite directions.

[0048] In this embodiment, the two first doors 2 are double-door structures located at both ends of the opening in the width direction. The bottom edge of the first door 2 is arranged along the length edge of the opening and is rectangular as a whole. The two second doors are located at both ends of the opening in the width direction. The bottom edge of the second door is lower than the bottom edge of the first door 2, or the length of the bottom edge of the second door 3 is less than the length of the edge of the opening that is rotatably connected to the second door 3. Both designs are conducive to ensuring that the second door 3 is stored inside the granary box 10 without interfering with the first door 2. The second door is preferably an isosceles trapezoid or an isosceles triangle that is thin at the top and wide at the bottom. In this way, the tarpaulin is wide at the top and narrow at the bottom when it is unfolded, which is conducive to forming a funnel; it is also conducive to leaving storage space for the tarpaulin when the second door 3 is stored. Figure 1 As shown, the second door is an isosceles trapezoid, and the length of the bottom side is less than the width of the opening. The tarpaulin 4 is fan-shaped as a whole, and its three sides are respectively fixed on the edge of the opening, the side of the first door and the side of the second door.

[0049] The two ends of the driving shaft 33 and the driven shaft 34, which are respectively parallel to the bottom edge of the second door 3, are rotatably supported by the upper area of ​​the grain bin box 10, and the driving shaft 33 and the driven shaft 34 are arranged at the upper position of the wall surface of the grain bin box 10. The driving shaft 33 and the driven shaft 34 are distributed at both ends of the length of the grain bin box 10, and the driving shaft 33 is parallel to the bottom edge of the second door.

[0050] One end of a fixed arm 35 is fixed to the driving shaft 33 and is located in the area of ​​the driving shaft 33 located inside the opening, and the fixed arm 35 points to the driving shaft 33; one end of the other fixed arm 35 is fixed to the passive shaft 34, and the other ends of the two fixed arms 35 are respectively hinged to one end of the corresponding rotating arm 36, and the other end of the rotating arm 36 is hinged to the lower half of the second door 3, that is, the hinge position is located above the bottom edge.

[0051] The second door 3, the rotating arm 36 and the fixed arm 35, which are hinged in sequence, form a four-bar mechanism. The plane where the rotating arm 36 and the fixed arm 35 are located is perpendicular to the second door 3. Since the fixed arm 35 rotates around the active shaft or the passive shaft respectively, the second door 3 rotates around its bottom edge, and the distance between the bottom edge and the active shaft or the passive shaft remains unchanged, and the rotating arm 36 connects the fixed arm 35 and the second door 3. In this way, the second door 3, the rotating arm 36 and the fixed arm 35 together form a four-bar linkage, and the movement of the fixed arm 35 rotating around the active shaft or the passive shaft can be output as the movement of the second door 3 rotating around its bottom edge.

[0052] The cylinder and crank 32 are preferably installed on the outside of the granary box 10, one end of the cylinder 31 is hinged to the granary box 10, and its other retractable end is hinged to one end of the crank 32; the other end of the crank 32 is fixed to the driving shaft 33; the cylinder 31 retracts and drives the crank 32 to rotate, the crank 32 rotates to drive the driving shaft 33 to rotate, the driving shaft 33 rotates to drive the two fixed arms 35 to rotate synchronously in the opposite direction, and the fixed arm 35 rotates to drive the second door 3 to rotate.

[0053] Preferably, the synchronization mechanism includes an active rod 41, an inclined rod 42 and a passive rod 43 which are rotatably connected in sequence;

[0054] One end of the active rod 41 is fixedly sleeved on the active shaft 33, and the other end thereof is rotatably connected to the inclined rod 42;

[0055] One end of the passive rod 43 is fixedly sleeved on the passive shaft 34, and the other end thereof is rotatably connected to the inclined rod 42;

[0056] When the second door 3 is unfolded, the active rod 41 tilts upward and outward, and the passive rod 43 tilts downward and inward to tilt the diagonal rod 42. The active rod 41 and the passive rod 43 have the same inclination angle, but are distributed on the upper and lower sides of the plane where the active shaft 33 and the passive shaft 34 are located.

[0057] Preferably, the first rotating component includes a pair of first rotating rods 51 and a pair of second rotating rods 52. The first rotating rod 51 is parallel to the fixed arm 35, one end of which is fixed to the active shaft 33 or the passive shaft 34, one end of which is connected to one end of the second rotating rod 52 through a joint bearing, and the other end of the second rotating rod 52 is connected to the first door 2 through a joint bearing. The first rotating rod 51 and the second rotating rod 52 are foldable. There are two first rotating components, and each first rotating component drives one first door 2.

[0058] Preferably, the opening angle of the first door 2 is greater than the opening angle of the second door 3 .

[0059] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
