Grain suction machines can significantly improve the transfer speed of materials, reduce labor intensity and optimize warehouse management. In addition, modern grain suction machines also have the characteristics of flexible layout, easy movement, wide operation area and large conveying capacity, which can save a lot of manpower and material resources. In the process of flour production, grain suction machines can also be combined with other equipment to form a complex conveying system to meet different operation requirements. They can handle various types of grains such as wheat and rice, and can be used in various environments, including easily flying, toxic, explosive and high-temperature environments, which has a positive impact on improving the operating conditions of workers and preventing environmental pollution.

[0041] As Figures 1-4 As shown in a kind of grain suction machine's grain bag fixing device, including: grain suction machine 1, base 2, mounting bracket 3, fixed frame 4, chamber 5, cylinder 6, extrusion plate 7, force bar 8, fixed plate 9.Grain suction machine 1 is fixed with ground, base 2 is installed in one side of grain suction machine 1, mounting bracket 3 is fixedly arranged on base 2, fixed frame 4 is arranged at the top of mounting bracket 3, and fixed frame 4 is the load-bearing structure of multiple key components in the whole grain bag fixing device.It provides a whole frame support for chamber 5, cylinder 6 and subsequent clamping related components, to ensure the relative position relationship of each component stable.Chamber 5 is opened in fixed frame 4, and cylinder 6 is installed in chamber 5, as the power source of driving grain bag clamping action.When cylinder 6 starts, its output end pops out and drives extrusion plate 7 to move horizontally, so as to trigger a series of clamping actions, which is the key power component to realize the function of grain bag fixing.

[0042] In the embodiment, extrusion plate 7 is arranged at the output end of cylinder 6, two force bars 8 are arranged, one end of the two force bars 8 is movably installed at the two ends of extrusion plate 7, fixed plate 9 is installed on one side of fixed frame 4, the number of clamping plates 10 corresponds to the number of force bars 8, clamping plates 10 are movably installed at the two ends of fixed plate 9, and mounting grooves 11 are opened on clamping plates 10;The other end of force bar 8 is arranged in mounting groove 11, and the turning end of force bar 8 and clamping plate 10 is movably connected.The role of force bar 8 is to convert the horizontal thrust of extrusion plate 7 into inward clamping force on clamping plate 10, and through this structural design, it can be ensured that the two force bars 8 can act synchronously when extrusion plate 7 moves, so that clamping plate 10 stably clamps the grain bag inward.Extending clamping plate 12 is located below clamping plate 10;The top surface of extending clamping plate 12 is connected with the bottom surface of clamping plate 10, and bag along clamp 13 is arranged above clamping plate 10.Extrusion plate 7 is an intermediate component for transmitting the power of cylinder 6 to force bar 8.When cylinder 6 drives extrusion plate 7 to move, extrusion plate 7 can accurately transmit the thrust to force bar 8, so as to drive force bar 8 to move.

[0043] The bag edge clamp 13 further comprises: a clamp housing 131 provided above the clamping plate 10 and provided with a slot, a bottom of a first clamp 132 movably mounted in the slot of the clamp housing 131, the clamp housing 131 providing mounting space for the first clamp 132 and a second clamp 134, and the slot designed to enable the first clamp 132 to move inside, thereby realizing the clamping function of the bag edge. An arc transition surface 133 is arranged on one side of the first clamp 132, the second clamp 134 is located on the opposite side of the first clamp 132, a spring 135 has two ends connected with the first clamp 132 and the second clamp 134 respectively, one end of a transmission rod 136 is movably connected with one side of the second clamp 134, and a roller 137 is mounted on the other end of the transmission rod 136; the roller 137 is in contact with the arc transition surface 133, and a handle 138 is mounted on the other end of the transmission rod 136. When the handle 138 is pressed down to open the first clamp 132 and the second clamp 134, the spring 135 is elongated, and when the handle 138 is released, the spring 135 rebounds to reset the first clamp 132, so that the first clamp 132 and the second clamp 134 re-clamp the bag edge, thereby ensuring the automatic resetting function of the bag edge clamp 13 and ensuring that the bag opening is always in an open state.

[0044] It should be noted that the grain bag fixing device of the grain suction machine designed by the utility model is used to place the grain bag vertically on the base 2, start the air cylinder 6, and the output end of the air cylinder 6 pops out to drive the extrusion plate 7 to move horizontally. Once the extrusion plate 7 moves, it will drive the force applying rod 8 to apply force to the turning end of the clamping plate 10. The clamping plate 10 will be clamped inwardly to clamp and restrain the grain bag together with the extension clamping plate 12 below, so that the grain bag is kept vertically placed. Then the handle 138 is manually pressed down to drive the other end of the transmission rod 136 to rotate downwardly at an angle, and the roller 137 will gradually roll downwardly to the lower side of the arc transition surface 133. Since the arc transition surface 133 is wide and the force applying point of the handle 138 is downward, the bottom of the first clamp 132 is squeezed, the top of the first clamp 132 is opened outwardly, and the spring 135 is also stretched. At this time, the bag opening of the grain bag is placed at the clamping range of the bag edge clamp 13, the handle 138 is released, the spring 135 rebounds to reset the first clamp 132, and the first clamp 132 and the second clamp 134 clamp the bag opening, so that the bag opening is always kept in an open state. At this time, the grain suction machine 1 is started again to directly suck the wheat in the grain bag without the need of tilting the grain bag to a specific place for sucking, which is simple and fast.
