Abstract

This invention relates to an automatic unloading food trolley, comprising a mobile vehicle with a hopper that can be raised and lowered at its front end. The hopper is equipped with a tilting device that allows the top opening of the hopper to tilt downwards. A telescopic plate is located on one side of the hopper's inner cavity near the opening, positioned on the downward-facing side after the hopper is tilted. After tilting, the telescopic plate extends from the hopper's opening, carrying the material out of the hopper. The mobile vehicle's transfer and lifting functions facilitate the transfer of the hopper and the loading and unloading processes. The tiltable design of the hopper and the tiltable top opening facilitate loading and unloading. A rack and pinion are located at the bottom of the hopper, meshing with a gear. A motor drives the gear to rotate, and when the gear meshes with the rack, it tilts the hopper. The process is stable and easy to control. The extendable telescopic plate inside the hopper helps the material escape from the opening, facilitating thorough unloading.

Description

Technical Field

[0001] This invention relates to the field of material transportation technology, specifically to an automatic unloading food dumper. Background Technology

[0002] Yellow rice wine is a fermented wine made primarily from rice, millet, sorghum, corn, wheat, and water, through the addition of koji (fermentation starter) and / or some enzyme preparations and yeast as saccharifying and fermenting agents. After the rice is steamed in a rice steamer, it needs to be cooled, mixed with koji, and then transferred to a fermentation tank for saccharification and fermentation. Traditionally, the rice was transferred manually using carts. This method was not only labor-intensive and inefficient, but also detrimental to product quality control. Later, some companies adopted simple tipper trucks for transportation. However, when the tipper truck tilts to pour the rice, due to the limitations of the tipper itself and the stickiness of the rice, it is difficult for the rice to quickly detach from the tipper and enter the fermentation tank. Manual assistance with rakes is still required for unloading. Sometimes, even after unloading, the rice accumulates on the edge of the tank, requiring manual raking to move it to the center. The efficiency of unloading remains low, and the improvement in labor efficiency is not significant. Furthermore, workers standing next to the tipper truck and fermentation tank while unloading pose safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide an automatic unloading rice dumping cart to solve the technical problems of low efficiency in transferring cooked rice and slow unloading speed in the rice wine brewing process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] An automatic unloading food dumping cart includes a mobile vehicle with a liftable hopper with an open top at the front end. The hopper is equipped with a tilting device that allows it to tilt to one side. A telescopic plate is installed inside the hopper on the inner side of the side in which the hopper tilts. After the hopper is tilted, the telescopic plate slides outward along the inner wall of the hopper to deliver the material inside.

[0006] As a preferred embodiment, the front end of the mobile vehicle is provided with a gantry, and a vertical hydraulic cylinder is provided in the middle of the base of the gantry. Two rotatable sprockets are provided on the top two sides of the free end of the hydraulic cylinder. One end of the chain on the two sprockets is fixed to the base, and the other end of the two chains is fixed to the first slider. The two sides of the first slider are slidably embedded in the vertical grooves on both sides of the gantry. The first slider is fixedly connected to one side of the frame around the hopper.

[0007] In a preferred embodiment, the hopper is rotatably mounted on two supporting side plates on opposite sides. The two supporting side plates extend downward beyond the bottom of the hopper and are connected by a base plate below the bottom of the hopper. A rack is provided in the center of the bottom surface of the hopper along the circumferential direction of rotation. A motor is provided on a horizontal extension plate on one side of the base plate. An axially horizontal gear is provided on the output end of the motor. The axis of the gear is parallel to the circumferential axis of the hopper rotation. The gear meshes with the rack, and the rotation of the gear drives the hopper to rotate.

[0008] In a preferred embodiment, the lower part of the telescopic plate is provided with second sliders on both sides of the side facing the inner wall of the hopper, and slide rails are provided on both sides of the opposite inner side of the hopper in the direction of sliding out of the opening. The two second sliders are slidably mounted on the two slide rails respectively, and a stop block is provided near the opening of the slide rail to prevent the second sliders from falling out.

[0009] In a preferred embodiment, the telescopic plate is connected to one end of two chains on both sides of its edge near the bottom of the hopper, and the other ends of the two chains are fixed to the bottom sides of the hopper. When the hopper tilts and flips, the telescopic plate slides out under gravity.

[0010] As a preferred embodiment, the surface of the telescopic plate facing the inner cavity is provided with anti-slip texture.

[0011] As a preferred embodiment, the transfer vehicle includes a forklift.

[0012] The beneficial effects of this invention are as follows: the hopper is height-adjustable and mounted on a mobile vehicle, utilizing the vehicle's transfer and lifting functions to facilitate the transfer of the hopper and the loading and unloading processes. The hopper is also tiltable, with an adjustable top opening for easy loading and unloading. A rack is installed at the bottom of the hopper, meshing with a gear. A motor drives the gear to rotate, and when the gear meshes with the rack, it causes the hopper to tilt, resulting in a stable and easy-to-control process. An extendable telescopic plate is installed inside the hopper, which helps the material to escape from the opening, facilitating more thorough unloading. Attached Figure Description

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figs. 1-4 The automatic unloading food transfer cart shown includes a mobile vehicle 1, which is a forklift. Utilizing the mobility of the forklift and the lifting function on the forklift mast 12, the hopper 2 can be moved horizontally and lifted. The front end of the mobile vehicle 1 is equipped with a liftable hopper 2 with an opening at the top. The hopper 2 is combined with the lifting structure on the forklift mast 12. The hopper 2 is equipped with a tilting device that can drive the hopper 2 to tilt to one side, thus enabling the hopper 2 to tilt and unload. This realizes the process of transferring and automatically unloading materials after the hopper 2 is loaded.

[0021] Specifically, a telescopic plate 4 is installed inside the hopper 2. The telescopic plate 4 is located on the inner side of the hopper 2 on the side of the tilting direction. After the hopper 2 is flipped, the telescopic plate 4 slides outward along the inner wall of the hopper 2 to deliver the material in the hopper (2). After the hopper 2 is tilted and flipped at a certain angle, the inner wall of the side where the telescopic plate 4 is located tilts outward and downward, and the telescopic plate 4 on it will slide outward. Since the telescopic plate 4 is also in a tilted state, all the rice in the hopper 2 is piled on the telescopic plate 4. Under the action of its own weight and the weight of the rice, the telescopic plate 4 slides out from the opening of the hopper 2. After the telescopic plate 4 slides out a certain distance, it stops due to the limit position, while the rice on the telescopic plate 4 continues to slide down and fall due to inertia, thus completing the unloading.

[0022] In one embodiment, the lower part of the telescopic plate 4, facing the inner wall of the hopper 2, is provided with two second sliders 42 on both sides. On the opposite inner side of the hopper 2, slide rails 41 are provided on both sides in the direction of sliding out of the opening. The two second sliders 42 are slidably mounted on the two slide rails 41. A stop block 43 is provided near the opening of the slide rail 41 to prevent the second sliders 42 from dislodging. The cooperation between the sliders 42 and the slide rails 41 on the inner wall of the telescopic plate 4 opposite to the hopper 2 ensures smooth sliding of the telescopic plate 4. The second sliders 42 on the telescopic plate 4 are limited by the stop block 43 and stop sliding downwards.

[0023] In another implementation, the telescopic plate 4 is connected to one end of two chains 44 on both sides of its edge near the bottom of the hopper 2. The other ends of the chains 44 are fixed to the bottom sides of the hopper 2. When the hopper 2 tilts and flips, the telescopic plate 4 slides out under gravity. As the telescopic plate 4 slides downward under gravity, it stops sliding out due to the traction force of the chains 44. The overall structure is simple and easy to clean. The length of the chains 44 is such that more than half of the telescopic plate 4 slides out of the hopper 2 when it slides out of the opening of the hopper 2. In this way, the end of the telescopic plate 4 that slides out of the hopper 2 will tilt downward to increase the tilt angle and accelerate the sliding of rice off the telescopic plate 4. To ensure that the outer end of the telescopic plate 4 tilts downward, the position where the chains 44 connect to the bottom of the hopper 2 is not on the same plane as the inner wall of the hopper 2 where the telescopic plate 4 is located, but is located on the front side of the inner wall.

[0024] As a preferred option, the telescopic plate 4 is preferably made of patterned plate, and more preferably, a layer of Teflon is coated, adhered, or plated on the surface of the telescopic plate.

[0025] The mobile vehicle 1 is equipped with a mast 12 at its front end. A vertical hydraulic cylinder 3 is mounted on the center of the base 11 of the mast 12. Two rotatable sprockets 31 are mounted on the top two sides of the free end of the hydraulic cylinder 3. One end of the chain 32 on each sprocket 31 is fixed to the base 11, and the other end is fixed to a first slider 26. The two sides of the first slider 26 are slidably embedded in opposing vertical grooves on both sides of the mast 12. The first slider 26 is fixedly connected to one side of the perimeter frame of the hopper 2. Using the automatic lifting device on the forklift mast 12, with the hydraulic cylinder 3 as the driving component, the cylinder 3 drives the top sprocket 31 to rise. One end of the chain 32 on the sprocket 31 is fixed, and the other end of the chain 32 drives the fixedly connected first slider 26 to rise. The first slider 26 is fixedly connected to one side of the bottom plate 22 of the hopper 2.

[0026] The hopper 2 is rotatably mounted on two supporting side plates 21 on opposite sides. The two supporting side plates 21 extend downwards beyond the bottom of the hopper 2 and are connected below the bottom of the hopper 2 by a base plate 22. A rack 25 is arranged along the circumferential direction of the hopper 2's bottom surface. A motor 23 is mounted on a horizontal extension plate on one side of the base plate 22. An axially horizontal gear 24 is mounted on the output end of the motor 23. The axis of the gear 24 is parallel to the circumferential axis of the hopper 2's rotation. The gear 24 meshes with the rack 25, and its rotation causes the hopper 2 to rotate. The hopper 2 uses the meshing of the gear 24 and the rack 25 at its bottom, with the motor 23 as the driving force, to achieve the rotation of the hopper 2. The rotation process is stable, easy to control, and has a simple structure.

[0027] Furthermore, the surface of the telescopic plate 4 facing the inner cavity is provided with anti-slip texture. When the telescopic plate 4 slides down, it can simultaneously slide out the material on top.

[0028] The working process of this invention is as follows:

[0029] As shown in Figures 1-4, first, fill hopper 2 with material. Then, start the mobile vehicle 1 to transport hopper 2 and material. Finally, after reaching the unloading point, the hydraulic cylinder 3 rises, hopper 2 rises, the motor 23 rotates, hopper 2 flips downward, the telescopic plate 4 slides down, the material falls, and the unloading is completed. The motor 23 drives hopper 2 to straighten, and the mobile vehicle 1 moves hopper 2 away.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
