[0001] The utility model relates to the technical field of chestnut production, in particular to a weighing device for chestnut packaging. Background Art

[0002] Packing means packing items with paper, cloth, sacks, packaging bags, etc.; chestnuts generally refer to chestnuts. Chestnuts are deciduous trees of the genus Castanea in the Fagaceae family, with thick stems and branches in a cylindrical shape; the surface is dark green with fine vertical lines and small hairs; with the development of the times, chestnut processing companies now use packaging equipment to weigh and pack chestnuts after completing chestnut processing, replacing the traditional manual weighing and packaging work.

The upper surface of the connecting plate is fixedly connected, the upper surface of the connecting plate is fixedly connected with a damping sleeve, the inner wall of the damping sleeve is slidably connected with a connecting frame, the connecting frame is bolted to the lower surface of the collecting bucket, the lower surface of the collecting bucket is fixedly connected with a U-shaped block, the side surface of the U-shaped block is provided with a rotating hole, the inner wall of the U-shaped block is rotatably connected with a connecting arm, the upper surface of the connecting plate is fixedly connected with an H-shaped frame, the inner wall of the H-shaped frame is slidably connected with an extrusion frame, the connecting arm is rotatably connected to the inner wall of the extrusion frame, the side surface of the extrusion frame is fixedly connected with a compression spring, and the compression spring is fixedly connected to the inner wall of the H-shaped frame.

[0007] Preferably, the number of the damping sleeves is four, and the four damping sleeves are diagonally arranged with respect to the connecting plate.

By installing the four damping sleeves on the connecting plate, the resistance generated by the resetting of the connecting frame can be increased when the connecting frame is reset, so as to slow down the resetting speed of the connecting frame and improve the stability of the connecting frame during the resetting process.

[0008] Preferably, the connecting arm is arranged in a T shape, and the number of the connecting arms is four, and the four connecting arms are arranged diagonally with respect to the collecting bucket.

The rack and the rotating shaft can be connected by the transmission gear installed on the surface of the rotating shaft, thereby ensuring that the rack can cooperate with the rack to drive the rotating shaft to rotate when moving.

[0012] Preferably, a circular hole is opened on the side surface of the protective cover, the driving end of the cylinder is slidably connected to the inner wall of the circular hole, and a square hole is opened on the side surface of the protective cover, and the rack and the transmission gear are adapted to the specifications of the square hole.

[0014] In the utility model, by setting an auxiliary component, when packing chestnuts, the conveying mechanism conveys the chestnuts to the collecting bucket, the collecting bucket collects the chestnuts, and cooperates with the weighing device to weigh the chestnuts. After weighing, the shielding component is opened, and the chestnuts in the collecting bucket are guided by the lower hopper and fall into the packaging bag above the conveyor belt; when the conveying mechanism conveys the chestnuts to the inside of the lower hopper, the chestnuts generate an impact at the moment of contacting the lower hopper, and at the same time, the collecting bucket pushes the connecting frame and the U-shaped block downward under the action of the impact force, and the connecting frame is displaced under the guidance of the damping sleeve. During the movement, the U-shaped block cooperates with the connecting arm to push the extrusion frame, and the extrusion frame extrudes the compression spring under the guidance of the H-shaped frame. The compression spring is squeezed and deformed, and the impact force generated by the collecting bucket is absorbed. By setting the auxiliary component, the equipment can absorb the impact force generated when weighing, thereby reducing the problem that the impact force generated by the equipment directly falls on the weighing mechanism, which is easy to cause the weighing mechanism to fail, and further improves the accuracy and service life of the equipment weighing mechanism.

[0015] In the utility model, by setting a shielding component, when the equipment completes weighing and the chestnuts need to be sent into the packaging bag, the cylinder is energized to cooperate with the connecting ring to push the rack side, the rack meshes with the transmission gear, and drives the rotating shaft to rotate, and the rotating shaft drives the baffle, and the baffle gradually unfolds under the action of the rotating shaft and loses the shielding effect on the collecting bucket. When the discharge port of the collecting bucket is opened, the chestnuts in the collecting bucket can fall into the packaging bag through the discharge port and the discharge hopper. By setting the shielding component, the stability of the shielding structure of the equipment is increased, the problem of poor stability when the equipment adopts the spring elastic force to constrain the shielding structure is reduced, and the practicality of the equipment is further improved.

[0025] In this embodiment: the auxiliary component 8 includes a connecting plate 81, which is fixedly connected to the upper surface of the weighing device 5, and a damping sleeve 82 is fixedly connected to the upper surface of the connecting plate 81, and a connecting frame 83 is slidably connected to the inner wall of the damping sleeve 82, and the connecting frame 83 is bolted to the lower surface of the collecting bucket 6, and a U-shaped block 84 is fixedly connected to the lower surface of the collecting bucket 6, and a rotating hole is opened on the side surface of the U-shaped block 84, and a connecting arm 85 is rotatably connected to the inner wall of the U-shaped block 84 located at the rotating hole, and an H-shaped frame 86 is fixedly connected to the upper surface of the connecting plate 81, and an extrusion frame 87 is slidably connected to the inner wall of the extrusion frame 87, and the connecting arm 85 is rotatably connected to the inner wall of the extrusion frame 87, and a compression spring 88 is fixedly connected to the side surface of the extrusion frame 87, and the compression spring 88 is fixedly connected to the inner wall of the H-shaped frame 86.

[0026] Specifically, there are four damping sleeves 82, which are diagonally arranged with respect to the connecting plate 81. The number of the connecting frames 83 matches the damping sleeves 82. By installing the four damping sleeves on the connecting plate 81, the resistance generated by the resetting of the connecting frame 83 can be increased when the connecting frame 83 is reset, so as to slow down the resetting speed of the connecting frame 83 and improve the stability of the connecting frame 83 during the resetting process.

At the same time, the center of the rotating shaft 91 of the baffle 92 can be determined during the rotation of the baffle 92 to ensure the stability of the baffle 92.

[0032] Specifically, the rotating shaft 91 passes through the side surface of the collecting bucket 6, and the transmission gear 93 abuts against the side surface of the collecting bucket 6.

[0033] Specifically, a round hole is opened on the side surface of the protective cover 97, and the driving end of the cylinder 94 is slidably connected to the inner wall of the round hole. A square hole is opened on the side surface of the protective cover 97, and the rack 96 is adapted to the specifications of the square hole.

[0034] In this embodiment, the protective cover 97 installed on the side of the collecting bucket 6 can protect the rack 96 and the transmission gear 93 to reduce the entry of dust and other impurities into the meshing part, causing the meshing part to get stuck.

[0035] Working principle: When packing chestnuts, the conveying mechanism conveys the chestnuts to the collecting hopper 6, which collects the chestnuts and weighs them in cooperation with the weighing device 5. After weighing, the shielding component 9 is opened, and the chestnuts in the collecting hopper 6 are guided by the lower hopper 7 and fall into the packaging bag above the conveyor belt 2; when the conveying mechanism conveys the chestnuts to the lower hopper 7, the chestnuts generate an impact at the moment of contact with the lower hopper 7, and at the same time, the collecting hopper 6 pushes the connecting frame 83 and the U-shaped block 84 downward under the action of the impact force, and the connecting frame 83 is displaced under the guidance of the damping sleeve 82, and the U-shaped block 84 cooperates with the connecting arm 85 to push the connecting frame 83 and the U-shaped block 84 in the process of moving. The extrusion frame 87 is moved, and the extrusion frame 87 squeezes the compression spring 88 under the guidance of the H-shaped frame 86. The compression spring 88 is squeezed and deformed, and absorbs the impact force generated by the collecting bucket 6; in addition, when the equipment completes weighing and needs to send the chestnuts into the packaging bag, the cylinder 94 is energized to cooperate with the connecting ring 95 to push the rack 96 side, and the rack 96 engages with the transmission gear 93 and drives the rotating shaft 91 to rotate. The rotating shaft 91 drives the baffle 92. The baffle 92 is gradually expanded under the action of the rotating shaft 91 and loses its shielding effect on the collecting bucket 6. When the discharge port of the collecting bucket 6 is opened, the chestnuts in the collecting bucket 6 can fall into the packaging bag through the discharge port and the discharge bucket 7.
