Abstract
Description
Technical Field
[0001] This utility model relates to the field of flour production technology, and in particular to a flour conveying and storage device. Background Technology
[0002] In the flour processing and food production sectors, the transportation and storage management of bagged flour is a key aspect of improving efficiency. However, when using transfer vehicles for transportation, multiple flour bags are typically piled up on the vehicle. When these flour bags are transported to a designated location awaiting retrieval, as the upper bags are removed one by one, operators must repeatedly bend over to grab the remaining bags. This bending over is particularly pronounced when retrieving bags at the bottom. Studies have shown that this prolonged, repetitive bending motion easily leads to lumbar muscle strain, not only reducing work efficiency but also posing significant occupational health risks. Furthermore, when performing large-angle bending movements, the operator's vision is obstructed, increasing the risk of handling errors and increasing the probability of flour bags falling and breaking. Utility Model Content
[0003] In order to overcome the problems mentioned in the background art, the present invention provides a flour conveying and storage device.
[0004] The technical solution is: a flour conveying and storage device, comprising:
[0005] trolley;
[0006] A fixed frame is fixed to the upper surface of the trolley. The fixed frame is detachably equipped with a swing frame. The swing frame and the fixed frame form a limiting frame for neatly stacking flour bags.
[0007] Four fixed posts are all fixed to the upper surface of the trolley and are slidably provided with a sliding plate.
[0008] A scissor bracket is installed between the sliding plate and the trolley, and the scissor bracket is used to control the movement of the sliding plate;
[0009] Multiple fixed rods are fixedly connected to the trolley, and the scissor frame is slidably connected to the fixed rods. A tension spring is fixedly connected between the scissor frame and the fixed rods, and the tension spring is used to control the extension and retraction of the scissor frame.
[0010] Furthermore, the limiting frame formed by the swing frame and the fixed frame is divided into three parts: two equidistant parts and one variable diameter part, wherein the area enclosed by the variable diameter part gradually decreases from top to bottom.
[0011] Furthermore, the fixed column is slidably provided with evenly distributed sliding columns, and a first spring is fixedly connected between the sliding column and the adjacent fixed column. The sliding column is provided with a swinging member for limiting rotation, and a torsion spring is installed between the swinging member and the adjacent sliding column.
[0012] Furthermore, it also includes:
[0013] Four cylindrical rods are slidably mounted on the sliding plate;
[0014] A support plate is fixed to the upper end of the four cylindrical rods. Four second springs are fixed between the support plate and the sliding plate. The support plate is rotatably equipped with a plurality of evenly distributed rollers.
[0015] Furthermore, the sliding plate is fixedly connected to an elastic element, which has multiple elliptical holes and is used to support the support plate.
[0016] Furthermore, the sliding plate is fixedly connected to four fixed shells, and the cylindrical rod penetrates the adjacent fixed shells and slides in a sealed manner with them. The fixed shells are filled with liquid, and the cylindrical rod is fixedly connected to a fixed ring. The fixed ring slides in a sealed manner with the adjacent fixed shells, and the fixed ring has circumferentially equidistant circular holes.
[0017] The beneficial effects of this utility model are as follows: By setting up a structure with elastic driving force provided by a tension spring, after the flour bags are removed layer by layer, the sliding plate is driven to move upward stably, thereby realizing the automatic lifting of the remaining flour bags. This reduces the bending degree of the operator during the material handling process, significantly reduces the risk of lumbar muscle strain caused by repetitive bending movements, and improves work efficiency and operating comfort. The second spring and elastic element buffer the impact force generated during the layer-by-layer stacking of bagged flour, avoiding packaging damage caused by collision or squeezing. In addition, the elastic buffer helps to disperse the stress generated by the load and extend the service life of the equipment. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings.
[0025] Example 1: A flour conveying and storage device, such as Figures 1-3 As shown, it includes: a trolley 1; a fixed frame 2, fixed to the upper surface of the trolley 1, a swing frame 3 rotatably mounted on the right side of the fixed frame 2, a sleeve rotatably mounted on the upper part of the swing frame 3, the swing frame 3 being connected to the fixed frame 2 through the sleeve, the swing frame 3 and the fixed frame 2 forming a limiting frame for neatly stacking flour bags, the limiting frame formed by the swing frame 3 and the fixed frame 2 is divided into three parts: two equidistant parts and one variable diameter part, wherein the area enclosed by the variable diameter part gradually decreases from top to bottom; and four rectangularly distributed fixed posts 4, all fixed to the trolley. The upper surface of 1 is slidably provided with a sliding plate 5; a scissor frame 6 is installed between the sliding plate 5 and the trolley 1, and the scissor frame 6 is used to control the movement of the sliding plate 5; three fixed rods 7 are all fixed to the trolley 1, and the scissor frame 6 is slidably connected to the fixed rods 7. Two tension springs 8 are symmetrically distributed between the scissor frame 6 and the fixed rods 7. The tension springs 8 are used to control the extension and retraction of the scissor frame 6. The two tension springs 8 are symmetrically arranged on a single fixed rod 7 and are used to drive the scissor frame 6 to extend and retract along its central axis. In the initial state, the scissor frame 6 is in the extended state.
[0026] like Figure 1 and Figure 4 As shown, the fixed column 4 is slidably provided with evenly distributed sliding columns 9. The sliding column 9 is fixedly connected to the adjacent fixed column 4 with a first spring 10. The limiting force generated by the four first springs 10 on the same horizontal plane on the sliding plate 5 is greater than the weight of a single flour bag. The sliding column 9 is provided with a swinging member 11 for limiting rotation. The swinging member 11 is provided with a V-shaped surface. A torsion spring is installed between the swinging member 11 and the adjacent sliding column 9.
[0027] When bagged flour needs to be transferred, the user places the bagged flour onto the sliding plate 5 in sequence. Under the action of gravity, the flour bag squeezes the sliding plate 5 downward. The downward movement of the sliding plate 5 squeezes the scissor frame 6, causing it to deform and stretch the tension spring 8 connected to it. When the sliding plate 5 moves downward and contacts the swinging component 11, the swinging component 11 hinders the downward movement of the sliding plate 5, preventing the sliding plate 5 from shaking back and forth.
[0028] When two bags of flour are stacked on the sliding plate 5 again, under the action of gravity, the sliding plate 5 moves downward and squeezes the adjacent swing member 11 to move. The swing member 11 and the sliding column 9 move and compress the adjacent first spring 10 until the sliding plate 5 passes the swing member 11. Then, the flour is stacked to make the sliding plate 5 continue to move downward.
[0029] After the stacked bags of flour are level with the fixed frame 2, the user moves the trolley 1 to the designated position and then takes out the bags of flour from the fixed frame 2 one by one. As the bags of flour are taken out, the squeezing force on the sliding plate 5 decreases. Under the tension of the tension spring 8, the sliding plate 5 moves in the opposite direction to lift the bags of flour on it, making it easier for the user to carry the bags of flour. When the sliding plate 5 moves up and passes the swing member 11, the sliding plate 5 will squeeze the swing member 11 to swing. After the sliding plate 5 passes the swing member 11, it swings back to its original position under the torque of the torsion spring connected to the swing member 11.
[0030] Example 2: Based on Example 1, such as Figure 3 and Figure 5 As shown, it also includes: four rectangularly distributed cylindrical rods 12, all slidably mounted on the sliding plate 5; a support plate 13, fixedly connected to the upper ends of the four cylindrical rods 12, with four second springs 14 fixedly connected between the lower surface of the support plate 13 and the upper surface of the sliding plate 5, the four second springs 14 respectively sleeved on the outer side of the four cylindrical rods 12, and multiple rollers evenly distributed on the support plate 13 for rotatable arrangement; and an elastic element 15 fixedly connected to the sliding plate 5, the elastic element 15 having multiple elliptical holes, the elastic element 15 being used to support the support plate 13.
[0031] like Figure 3 and Figure 5 As shown, four rectangularly distributed fixed shells 16 are fixed to the lower surface of the sliding plate 5, and the cylindrical rod 12 penetrates the adjacent fixed shells 16 and slides in a sealed manner with them. The fixed shells 16 are filled with liquid, and a fixed ring 17 is fixed to the cylindrical rod 12 and slides in a sealed manner with the adjacent fixed shells 16. The fixed ring 17 has circumferentially distributed circular holes.
[0032] When bagged flour is placed on pallet 13, the collision between the stacked flour bags is transmitted to pallet 13, causing the bagged flour to move and compress the elastic element 15. The deformation of the elastic element 15 absorbs and buffers the collision force. At the same time, pallet 13 drives the four cylindrical rods 12 and the fixing ring 17 to move within the fixing shell 16. During this process, the liquid in the fixing shell 16 flows through the round hole on the fixing ring 17. At this time, the flow resistance of the liquid further consumes the collision force between the flour bags, avoiding packaging damage caused by collision or compression.
[0033] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
