Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a fertilizer transportation cart. Background Art

[0002] Fertilizer transport cart. A cart is needed to transport biological organic fertilizer within the factory.

[0003] For example, a fertilizer transport cart with publication number CN208576579U has a structure including wheels, a fixed seat, a telescopic device, a mounting shaft, a mounting seat, a hand wheel, screws, a baffle, a grip, and a pad. The lower surface of the mounting seat fits with the upper surface of the telescopic device, the hand wheel is embedded and installed at the left end of the telescopic device, and the screw is threadedly connected to the baffle. The utility model provides a fertilizer transport cart with a telescopic device on the structure. The telescopic device is installed on the equipment. The transmission screw is driven by rotating the hand wheel, and the gear is driven by the transmission screw. The connecting gear is driven by the gear, and the screw is driven by the connecting gear, thereby driving the screw plate. The screw plate drives the tilting rod to squeeze and retract the telescopic plate, and the extrusion rod squeezes and retracts the telescopic plate at the same time. The storage plate can be retracted and retracted by the telescopic device, so that the storage amount is increased.

[0004] However, the device does not have the ability to assist in unloading. For unpackaged fertilizers, they are usually piled directly on the cart. If there is no auxiliary unloading mechanism, it will be difficult to unload all the fertilizers during unloading, and unloading will be more laborious. At the same time, the technical solution does not have the function of electric assistance, and it will be more laborious to push heavy objects, especially when going up and down slopes, and it may not be able to be pushed or pulled, thereby posing a danger to the user or surrounding personnel. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a fertilizer transport cart.

[0006] The utility model is achieved in this way:

[0007] A fertilizer transport cart comprises a moving mechanism and a storage mechanism, wherein the moving mechanism comprises a support seat, a pair of universal wheels and a pair of directional wheels are installed at the bottom of the support seat, a mounting cavity is opened at the top of the support seat, a pair of first connecting plates are installed at the bottom of the mounting cavity, and a first rotating shaft is rotatably connected between the pair of first connecting plates, an electric telescopic rod is installed on the outer side of the first rotating shaft, a handle is hinged at the top of the support seat, and a control panel is installed at the bottom of the handle, the storage mechanism comprises a storage main board, and a control panel is installed at the bottom of the storage main board near the axial center line A pair of second connecting plates, and the pair of second connecting plates are rotatably connected with the second rotating shaft on the side close to each other, the telescopic end of the electric telescopic rod is connected to the pair of second rotating shafts, a connecting shaft is connected between one end of the storage main board and the mounting cavity, a differential is installed at the bottom of the support seat, and an output shaft is connected between the output ends on both sides of the differential and a pair of directional wheels, a torque motor is installed at the bottom of the support seat through the machine base, and an input shaft is drivingly connected between the output end of the torque motor and the input end of the differential, and the control panel is electrically connected to the electric telescopic rod and the torque motor.

[0008] The beneficial effect of adopting the above further scheme is that the extension and retraction of the electric telescopic rod is controlled by the control panel, so that the electric telescopic rod that can rotate at both ends can drive the storage main board that can rotate around the connecting shaft to rotate, so that the storage main board becomes inclined. When the unpackaged pile of materials is transported, the inclined storage main board can assist the user in unloading, so as to achieve the purpose of saving effort. At the same time, the inclined storage main board can make the pile of materials unloaded more cleanly. At the same time, the torque motor can drive the input shaft to rotate at a constant speed, and transmit power to the directional wheel through the differential, so that the directional wheel rotates at a constant speed, so as to achieve the purpose of assisting the user to push the device, and output a predetermined value through the control panel, so that the torque motor can always maintain a fixed speed. When the speed of the uphill directional wheel slows down, the torque motor can reduce the torque, so that the speed of the directional wheel rises to a fixed value. When the speed of the downhill directional wheel speeds up, the torque motor can increase the torque, so that the speed of the directional wheel decreases to a fixed value, so that it can be safer when pushing the device uphill and downhill.

[0009] Furthermore, a pair of first fixing plates are installed on the top of the support seat, and an inert shaft is connected between the first fixing plates and the handle.

[0010] Furthermore, the width of the mainboard storage cavity is greater than the width of the installation cavity.

[0011] The beneficial effect of adopting the above further solution is that, by limiting the size of the storage mainboard, the support base can support the storage mainboard when it is laid flat, so as to prevent the electric telescopic rod from being crushed by the storage mainboard.

[0012] Furthermore, storage cavities are provided on both sides of the storage main board, and a storage secondary board is slidably provided in the storage cavity. Limiting grooves are provided on both sides of the storage secondary board, and limiting blocks are installed on both sides of the storage cavity, and the limiting blocks slide in the limiting grooves.

[0013] Furthermore, connecting grooves connected to the storage cavity are provided on the other two sides of the storage main board, and second fixing plates are installed on both sides of the connecting grooves of the storage main board. Fixed blocks sliding in the connecting grooves are installed on both sides of the storage secondary board, and the fixed blocks and the second fixing plates are fixed to each other.

[0014] Furthermore, fixing grooves are provided on both sides of the fixing block, the second fixing plate slides in the fixing grooves, a first fixing hole connected to the fixing grooves is provided on the top of the fixing block, a second fixing hole is provided on the top of the second fixing plate, a fixing rod slides in the first fixing hole, and the fixing rod slides in the second fixing hole.

[0015] Furthermore, a rod cap is installed on the top of the fixing rod, and a spring is connected between the bottom of the rod cap and the fixing block.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that when the storage secondary plate is extended, the area of ​​the storage main plate can be expanded, so that more materials can be transported, and through the use of limit blocks and limit blocks, part of the storage secondary plate is located in the storage cavity, and this part is used to support the storage secondary plate. After the storage secondary plate slides into place, the fixing rod is lifted, and the second fixing plate will slide into the fixing groove. At this time, the first fixing hole and the second fixing hole are aligned, and then the fixing rod is released to reset it under the action of the spring, so that it slides into the second fixing hole to fix the storage secondary plate.

[0017] Furthermore, the surfaces of the storage main board and the storage secondary board are both provided with anti-slip grooves.

[0018] The beneficial effects of the utility model are as follows: the fertilizer transport cart obtained by the utility model through the above design uses a control panel to control the extension and retraction of the electric telescopic rod, which can make the electric telescopic rod rotatable at both ends drive the storage main board rotatable around the connecting shaft to rotate, so that the storage main board becomes inclined. When the unpackaged pile is transported, the inclined storage main board can assist the user to unload the material, so as to achieve the purpose of saving effort. At the same time, the inclined storage main board can make the pile unload cleaner. At the same time, the torque motor can drive the input shaft to rotate at a constant speed, and transmit power to the directional wheel through the differential, so that the directional wheel rotates at a constant speed, so as to achieve the purpose of assisting the user to push the device, and output a predetermined value through the control panel, so that the torque motor can always maintain a fixed speed. When the speed of the directional wheel slows down on the uphill, the torque motor can reduce the torque, so that the speed of the directional wheel rises to a fixed value. When the speed of the directional wheel increases on the downhill, the torque motor can increase the torque, so that the speed of the directional wheel decreases to a fixed value, so that it is safer to push the device up and downhill.
