This kind of tipping bucket is not suitable for short-distance transportation of liquid materials and powder materials that are prone to generate dust. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a sliding hopper discharging hand trolley suitable for short-distance transportation of liquid materials and powder materials that are prone to generate dust.

[0005] To solve the above technical problem, the utility model includes a frame. Walking wheels are installed at the bottom of the frame. A sliding hopper is arranged at the upper part of the frame. Horizontal pipes are symmetrically arranged on both sides of the frame. The rear end of the horizontal pipe is a handle. An inserting rod is arranged inside the horizontal pipe. The front end of the inserting rod is fixedly connected to the bottom of the front end of the sliding hopper through a connecting block. A locking device is arranged at the rear end of the inserting rod and is matched with the horizontal pipe. The inserting rod can be locked at a position close to the rear end inside the horizontal pipe through the locking device. An unlocking device is arranged outside the horizontal pipe, and the unlocking device can unlock the locking device. A front support part is fixedly arranged at the front part of the frame.

[0006] The front end of the sliding hopper is open, and a door is hinged and installed at the opening. The door is hinged and connected to the bottom of the front port of the sliding hopper. A front support part is fixedly arranged at the front part of the frame. A limiting block is fixedly arranged at the lower end of the door. When the door is in the closed state, the limiting block abuts against the front side of the front support part.

[0007] To improve the tightness of the sliding hopper, the top of the sliding hopper is closed, and a feeding port is arranged at the top of the sliding hopper.

[0008] To prevent the material from overflowing to both sides when poured out from the front side, sector plates that fit on the inner walls of both sides of the front port of the sliding hopper are fixedly arranged on both sides of the door.

[0009] In a relatively simple design of the locking device, the locking device includes a blind hole opened on the inserting rod. A sliding locking block is installed in the blind hole through a second spring. A limiting hole that can be inserted and matched with the sliding locking block is opened at the corresponding position of the horizontal pipe. Under the action of the second spring, the outer end of the sliding locking block is inserted into the limiting hole to realize the locking of the inserting rod.

[0010] One of the relatively simple unlocking device designs, the unlocking device includes a button hinged and installed on the side of the external limit hole of the horizontal pipe. The button contacts the sliding locking block, and a torsion spring is installed at the hinge connection of the button. Unlocking is achieved by pressing the button to push the sliding locking block inward to disengage from the limit hole.

[0011] In order to open the door to the limit angle when the sliding hopper moves forward for discharging, the front part of the front support is an inclined surface slanting upward, and the limit block cooperates with the inclined surface. The included angle α between the limit block and the door is an obtuse angle.

[0012] In order to make the sliding hopper move more smoothly on the upper part of the vehicle frame, several rollers cooperating with the vehicle frame are provided at the bottom of the sliding hopper.

[0013] In summary, the user adds materials into the sliding hopper through the feeding port. After the user transfers the materials to the designated position by the handcart, raises the position of the handle, and then releases the locking of the locking device through the unlocking device. At this time, under the action of gravity, the sliding hopper slides forward under the guidance of the insertion rod. At this time, the limit block leaves the front support, the door opens, and the materials are poured out from the front port of the sliding hopper, realizing the automatic opening of the sliding hopper touching the ground and the door, better pouring out the materials. After the materials are poured out, the user adjusts the vehicle frame back to the horizontal state. At this time, under the action of the first spring, the insertion rod and the sliding hopper slide backward to the initial position, and the locking device locks the position of the insertion rod again, and the door closes automatically, which is suitable for short-distance transportation of liquid materials and powdery materials prone to generating dust. Brief Description of the Drawings

[0014] The following further describes the present invention in detail with reference to the drawings and specific embodiments:

[0015] Figure 1 is a schematic structural diagram of the present invention;

[0016] Figure 2 is a schematic structural diagram of the discharging use state of the present invention;

[0017] Figure 3 is a partial enlarged schematic diagram of the locking device and the unlocking device parts of the present invention. Specific Embodiments

[0018] Referring to the attached drawings, the hopper-dumping wheelbarrow includes a frame 1, with traveling wheels 2 installed at the bottom of the frame 1. There is a hopper 3 at the upper part of the frame 1. Horizontal pipes 4 are symmetrically arranged on both sides of the frame 1. The rear end of the horizontal pipe 4 is a handle. An insertion rod 5 is arranged inside the horizontal pipe 4. The front end of the insertion rod 5 is fixedly connected to the bottom of the front end of the hopper through a connecting block. A locking device is arranged at the rear end of the insertion rod 5 and is matched with the horizontal pipe. The insertion rod can be locked at a position near the rear end inside the horizontal pipe through the locking device. An unlocking device is arranged outside the horizontal pipe, and the unlocking device can release the locking of the locking device. After unlocking, the insertion rod can slide forward a certain distance along the horizontal pipe 4. A first spring 6 is arranged between the rear end of the insertion rod and the inside of the horizontal pipe, and the elastic force of the first spring 6 on the insertion rod points to the rear end of the insertion rod.

[0019] The top of the hopper is closed, and a feeding port 12 is arranged at the top of the hopper. The front end of the hopper is open, and a door 7 is hingedly installed at the opening. Sector plates 17 are fixedly arranged on both sides of the door 7 and are attached to the inner walls on both sides of the front port of the hopper. The arrangement of the sector plates 17 can prevent the material from overflowing to both sides when poured from the front side, which is suitable for the transportation of liquids. The door 7 is hingedly connected to the bottom of the front port of the hopper. A front support part 8 is fixedly arranged at the front of the frame. A limit block 9 is fixedly arranged at the lower end of the door 7. When the door 7 is in the closed state, the limit block 9 abuts against the front side of the front support part 8. At this time, the insertion rod is locked, and the hopper cannot move forward, and the door cannot be opened when in the closed state.

[0020] The front part of the front support part is an inclined surface 10 that slopes upward. The limit block 9 is matched with the inclined surface 10. The included angle α between the limit block and the door 7 is an obtuse angle. Through this design, the combination of the limit block and the door can form a lever structure, which can close the door tighter, and when the hopper moves forward to unload the material, the limit block can contact the ground so that the door can be opened to the limit angle, as Figure 2 shown.

[0021] Several rollers 11 that cooperate with the frame are arranged at the bottom of the hopper. This design can make the hopper move more smoothly on the upper part of the frame.

[0022] The locking device includes a blind hole 13 opened on the insertion rod. A sliding locking block 14 is installed in the blind hole 13 through a second spring. A limit hole 15 is opened at the corresponding position of the horizontal pipe. Under the action of the second spring, the outer end of the sliding locking block 14 is inserted into the limit hole to lock the insertion rod.

[0023] The unlocking device includes a button 16 hingedly installed on the side of the limit hole outside the horizontal pipe. The button contacts the sliding locking block 14. A torsion spring is installed at the hinge connection of the button. By pressing the button 16, the sliding locking block is pushed inwards to disengage from the limit hole to achieve unlocking.

[0024] Working principle: The user adds materials into the sliding hopper through the feeding port. After the user transfers the materials to the designated position by the trolley, raises the handle position, and then releases the locking of the locking device through the unlocking device. At this time, under the action of gravity, the sliding hopper slides forward under the guidance of the insertion rod. At this time, the limit block leaves the front support part and the door opens. As Figure 2 shown, at this time, the materials are poured out from the front port of the sliding hopper, realizing the automatic opening of the sliding hopper touching the ground and the door, and better pouring out the materials. After the materials are poured out, the user adjusts the vehicle frame back to the horizontal state. At this time, under the action of the first spring, the insertion rod and the sliding hopper slide backward to the initial position, and the locking device locks the insertion rod position again, and the door closes automatically, which is suitable for short-distance transportation of liquid materials.

[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
