[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 8 The present invention provides a technical solution: an automatic unloading device for a material collecting box, comprising: a funnel body 1, a funnel body 2 3 is fixedly installed at the bottom of the funnel body 1, two electric crocodile box doors 4 are symmetrically arranged at the bottom of the funnel body 2 3, two pin seats 14 are symmetrically arranged on the outer wall of the funnel body 1, and two vertical slide grooves are symmetrically opened on the outer walls of the two pin seats 14, and pin shafts 15 are slidably installed in the two slide grooves, and an electric push rod 2 is rotatably installed on the outer wall of the pin shaft 15, and the output end of the electric push rod 2 and the electric crocodile box door 4 are hingedly designed; the two electric crocodile box doors 4 are arc-shaped; the outer wall of the funnel body 2 3 is symmetrically opened with two assembly grooves, and the two assembly grooves are provided with a displacement mechanism that can make the electric crocodile box door 4 move downward; a detection mechanism 5, the detection mechanism 5 can monitor the material height inside the funnel body 1, and the detection mechanism is associated with the electric push rod 2.

[0028] In the existing technology, the traditional aggregate box is opened manually by a person to unload the materials inside the aggregate box, which may be dangerous. Moreover, when the materials inside the aggregate box are large in number, such as ore, the box door is easily stuck, and it is not easy to open the box door manually, which affects the unloading efficiency of the aggregate box. Moreover, when the materials enter the aggregate box, there is no material height detection device, and it is necessary to manually observe the material level height in the aggregate box to decide whether to unload. Manual observation is easily distracted, resulting in excessive overflow of materials, thus posing a safety problem. In this embodiment, by providing a funnel body 1 and a funnel body 2 3, the material enters the funnel body 1 and falls into the funnel body 2 3, and the bottom of the funnel body 2 3 is closed by an electric crocodile box door 4, so that the material is stored in the funnel body 1 and the funnel body 2 3, and the detection mechanism can detect the materials in the funnel body 1. The material height is detected. When the material accumulated inside the funnel body 1 reaches a certain height, the detection mechanism can trigger the displacement mechanism inside the assembly groove to make the electric crocodile box door 4 move downward. When the electric crocodile box door 4 moves to the preset position, the electric push rod 2 can be triggered to work, so that the electric crocodile box door 4 rotates and moves to both sides, thereby opening the bottom of the funnel body 2 3 to unload the material inside. By setting the displacement mechanism to make the electric crocodile box door 4 move downward relative to the funnel body 2 3, the friction between the electric crocodile box door 4 and the bottom of the funnel body 2 3 can be reduced, making it easier for the electric crocodile box door to move to both sides through the electric push rod 2. At the same time, it can prevent the accumulation of materials inside the funnel body 2 3 from causing the electric crocodile box door 4 and the bottom of the funnel body 2 3 to get stuck, thereby solving the problem of the electric crocodile box door 4 being stuck and causing the material to be unable to be unloaded, thereby improving the unloading efficiency of the aggregate box.

[0029] Among them, the more preferred embodiment is that the displacement mechanism includes an assembly block 6 arranged inside the assembly groove, and two rotating shafts 8 are symmetrically fixedly installed on the outer wall of the assembly block 6, and the two rotating shafts 8 are respectively fixedly connected to the two electric crocodile box doors 4. A displacement unit is provided inside the assembly groove, and the displacement unit can make the two electric crocodile box doors 4 move downward. By setting the assembly block 6, the outer wall of the assembly block 6 is symmetrically provided with two rotating shafts 8, so that the rotation points of the two electric crocodile box doors 4 rotate on the two rotating shafts 8. By setting the displacement unit, the assembly block 6 is displaced downward, thereby driving the two electric crocodile box doors 4 to move downward, so that the electric crocodile box doors 4 are rotated and displaced to both sides under the action of the electric push rod 2, so that the bottom of the funnel body 2 3 is opened, and the material accumulated inside is unloaded through the bottom of the funnel body 2 3. When the material is Funnel body 1 enters funnel body 2 3, thereby accumulating in the internal space of funnel body 1 and funnel body 2 3. When the material in the internal space accumulates to a certain height, it is detected by the detection unit, thereby triggering the displacement unit to work, thereby causing the assembly block 6 to move downward and driving the electric crocodile box door 4 to move downward. When the displacement unit moves to the preset position, it will trigger the electric push rod 2 to work, thereby causing the electric crocodile box door 4 to rotate and displace to both sides, thereby opening the bottom of the funnel body 2 3 to unload the material. By causing the electric crocodile box door 4 to move downward, the friction resistance of the electric crocodile box door 4 is reduced when it rotates and displaces to both sides under the action of the electric push rod 2. At the same time, it can prevent the material accumulated inside the funnel body 2 3 from causing the electric crocodile box door 4 to get stuck, thereby improving the unloading efficiency of the aggregate box and improving the safety of the unloading work.

[0030] Among them, the more preferred embodiment is that the displacement unit includes a telescopic rod 7 fixedly installed on the inner wall of the assembly cavity, and the output end of the telescopic rod 7 is fixedly connected to the assembly block 6. When the material enters the funnel body 2 3 from the funnel body 1, it is accumulated in the internal space of the funnel body 1 and the funnel body 2 3. When the material in the internal space accumulates to a certain height, it is detected by the detection unit, thereby triggering the telescopic rod 7 to work. The telescopic rod 7 causes the two electric crocodile box doors 4 to move downward through the assembly block 6. When the displacement reaches a preset position, the electric push rod 2 is triggered to work, thereby causing the two electric crocodile box doors 4 to rotate and displace, so that the bottom of the funnel body 2 3 is opened, so that the material inside it can be unloaded through the bottom. The telescopic rod 7 causes the electric crocodile box door 4 to move downward, thereby reducing the friction resistance between the electric crocodile box door 4 and the bottom of the funnel body 2 3, and at the same time, it can prevent the material inside the funnel body from causing the electric crocodile box door 4 to get stuck, and the electric push rod 2 cannot cause the electric crocodile box door 4 to rotate and displace, thereby improving the unloading efficiency of the aggregate box and preventing the electric crocodile box door 4 from getting stuck and causing the material to be unable to be unloaded.

[0031] Among the more preferred embodiments, two movable grooves are symmetrically opened inside the funnel body 2 3, two follower rods 11 are symmetrically arranged in the two movable grooves, one end of the two follower rods 11 extends into the assembly groove, and the other end of the two follower rods 11 is fixedly installed with the same loosening rod 16, and a plurality of toggle columns 13 are installed in a linear array on the outer wall of the loosening rod 16, and two return springs 12 are symmetrically installed at the bottom of the two movable grooves, and the ends of the two return springs 12 are fixedly connected to the loosening rod 16, and a driving unit is arranged in the assembly groove, and the driving unit can make the loosening rod 16 moves up and down. When the material passes through the funnel body 1 and enters the funnel body 2 3, when the material accumulated in the internal space of the funnel body 1 and the funnel body 2 3 reaches a certain height, under the monitoring of the detection mechanism, the telescopic rod 7 will be triggered to drive the assembly block 6 to move downward, so that the electric crocodile box door 4 moves downward. When the electric crocodile box door 4 moves to the preset position, the electric push rod 2 will be triggered to work, so that the two electric crocodile box doors 4 rotate and move, so that the bottom of the funnel body 2 3 is opened, so that the material accumulated inside is unloaded. The downward displacement of the electric crocodile box door 4 can prevent the electric crocodile box door 4 from getting stuck. The material cannot be unloaded, and the friction resistance of the electric crocodile box door 4 during rotation and displacement can be reduced. When the electric crocodile box door 4 rotates, the driving mechanism is driven to work. Under the action of the driving mechanism, the driven rod 11 vibrates up and down, thereby driving the loosening rod 16 to vibrate up and down, and the toggle column 13 on the loosening rod 16 will also move up and down with the loosening rod 16. When the material inside the funnel body 2 3 is accumulated, the material inside may be stuck inside the funnel body 2 3 under the action of gravity. When the material is stuck, the electric crocodile box door 4 rotates and displaces, causing the bottom of the funnel body 2 3 to break. The material inside the hopper body 23 is also unable to be unloaded due to the jamming reason. At this time, the material inside the hopper body 23 is vibrated and loosened by the up and down displacement of the toggle column 13. The up and down displacement of the toggle column 13 and the rotational displacement of the electric crocodile box door 4 are carried out simultaneously. Therefore, when the electric crocodile box door 4 rotates and displaces to open the hopper body 23, the accumulated material inside is loosened under the action of the toggle column 13, so that the material inside can be better unloaded, thereby improving the unloading efficiency of the material in the aggregate box and effectively preventing the probability of the internal material being stuck and unable to be unloaded.

[0032] Among them, the more preferred embodiment is that the driving unit includes a plurality of driving rods 9 arrayed and mounted on the outer wall of the rotating shaft 8. The driving rods 9 can conflict with the driven rods 11 when rotating. When the materials are accumulated to a certain height in the internal space of the funnel body 1 and the funnel body 2 3, the detection mechanism 5 detects that the height reaches the unloading height. At this time, the detection mechanism 5 sends an electrical signal to drive the telescopic rod 7 to drive the assembly block 6 to move downward, so that the electric crocodile box door 4 moves downward. When the telescopic rod 7 moves to the preset position, it will send an electrical signal to drive the electric push rod 2 to work, drive the electric crocodile box door 4 to rotate and move, so that the bottom of the funnel body 2 3 is opened to realize the unloading work. When the electric crocodile box door 4 rotates and moves, it drives the two The rotating shaft 8 rotates, and at the same time drives the multiple driving rods 9 arrayed on the rotating shaft 8 to rotate and move. During the rotation and displacement of the driving rod 9, it will conflict with the driven rod 11, thereby driving the driven rod 11 to move upward. When the driven rod 11 moves to a certain position, the driving rod 9 will pass through the driven rod 11. At this time, the driven rod 11 moves downward under the action of the reset spring 12, and multiple driving rods 9 pass through in turn, thereby causing the driven rod 11 to move up and down, thereby causing the loosening rod 16 to move up and down, so that the multiple toggling columns 13 on the outer wall of the funnel body 2 3 can toggle the material inside the funnel body 2 to loosen the material, thereby better unloading and preventing the internal material from getting stuck, resulting in the inability to unload.

[0033] Among the more preferred embodiments, the detection mechanism 5 includes a plurality of bases 51 arrayed and mounted on the inner wall of the funnel body 1, a rotating shaft 55 is fixedly mounted on the inner wall of the plurality of bases 51, a detection rod 52 is rotatably mounted on the outer wall of the rotating shaft 55, a reset spring 2 53 is fixedly mounted between the outer wall of the detection rod 52 and the inner wall of the base 51, a sensing column 54 is fixedly mounted on the inner wall of the base 51, and the detection rod 52 can collide with the sensing column 54 when rotating. When the logistics enters the funnel body 1 and the funnel body 2 3, when the material inside reaches a certain height, pressure is applied to the detection rod 52, so that the detection rod 52 rotates and displaces to collide with the sensing column 54 mounted on the base 51, thereby sending an electrical signal. The four internal surfaces of the funnel body 2 3 are linearly arrayed with multiple driving units. When the number of triggered driving units reaches a preset number, the telescopic rod 7 and the electric push rod 2 will be driven to work. When the materials inside the funnel body 1 and the funnel body 2 3 are unloaded, the detection rod 52 returns to the preset position under the action of the reset spring 2 53, thereby realizing the monitoring of the height of the downward moving materials. When the internal materials are unloaded, the electric push rod 2 first works to drive the electric crocodile box door 4 to rotate and displace, so that the two electric crocodile box doors 4 are in abutment state, and then the telescopic rod 7 is triggered to work, driving the electric crocodile box door 4 to move upward, thereby closing the bottom of the funnel body 2 3, so that the next loading can be carried out.

[0034] Among the more preferred embodiments, the bottom of the funnel body 23 is of flat-plate design. When the electric crocodile box door 4 is of arc-shaped design, the bottom of the funnel body 23 is of flat-plate design. When the material inside the funnel body 23 is ore of different sizes and heavy weight, it is easy to cause the electric crocodile box door 4 to get stuck and unable to open. Through this design, the problem of the electric crocodile box door 4 getting stuck can be effectively prevented, and the contact area between the electric crocodile box door 4 and the bottom of the funnel body 23 is reduced, thereby reducing the friction resistance when the electric crocodile box door 4 rotates and displaces, thereby improving the opening efficiency of the electric crocodile box door 4 and preventing sticking.

[0035] In a preferred embodiment, the bottom of the funnel body 2 3 is designed in a wave-tooth shape, and when the electric crocodile box door 4 is designed in an arc shape, such as Figure 8 As shown, when the bottom of the funnel body 23 is designed in a wavy tooth shape, when the material inside the funnel body 23 is small and fine, such as sand and gravel, this design can ensure that the sealing of the bottom of the funnel body 23 can be guaranteed when loading materials, and can also prevent the electric crocodile box door 4 from getting stuck, preventing the electric crocodile box door 4 from getting stuck and causing the material to be unable to be unloaded.

[0036] Among them, the more preferred embodiment is that the inner bottom of the two electric crocodile box doors 4 are both arranged with multiple rollers in an array. When the detection mechanism 5 detects that the internal material reaches the unloading height, the electric crocodile box door 4 is rotated and displaced by the electric push rod 2, so that the bottom of the funnel body 2 3 is opened, thereby realizing the unloading work. By arranging multiple rollers on the inner bottom of the electric crocodile box door 4, when the electric crocodile box door 4 is rotated and displaced, the friction resistance between the electric crocodile box door 4 and the bottom of the funnel body 2 3 can be reduced through the rollers, thereby reducing the workload of the electric push rod 2, thereby improving the service life of the electric push rod 2.

[0037] Working principle: When the automatic unloading device of the aggregate box is in use, the electric crocodile box door 4 is displaced downward by the telescopic rod 7, and the electric crocodile box door 4 is rotated and displaced by the electric push rod 2, thereby realizing unloading and driving the up and down displacement of the toggle column 13 to loosen the material inside the funnel body 2 3. When the bottom of the funnel body 2 3 is opened, the internal material is loosened, thereby improving the unloading efficiency of the aggregate box.

[0038] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
