Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to an automatic feeding device with adjustable feeding amount in a hopper. Background Art

[0002] In modern industrial production, hoppers are important equipment for storing, transporting and pouring materials, and are widely used in many fields such as chemicals, pesticides, medicines, feeds, warehousing, shipping and logistics distribution. The design of hoppers usually adopts a cone or other shape that facilitates the flow of materials to ensure that the materials can flow out or pour out smoothly from the bottom. However, with the improvement of production efficiency and the continuous development of automation technology, the traditional manual feeding method can no longer meet the needs of large-scale and high-efficiency production.

[0003] In this context, the hopper filling device came into being. This device is designed to automatically replenish materials in the hopper to improve production efficiency, reduce manufacturing costs and reduce manual intervention. The technical development of the hopper filling device has gone through several stages, from the initial simple mechanical structure to today's intelligent and automated control system, and its functions and performance have been significantly improved.

[0004] In the patent entitled "A Precision Feeding Equipment" and the publication number CN112875228B, it is proposed that in the prior art, the hopper conveys the material to the feeding mechanism, and the feeding mechanism conveys the material. Since a large amount of material is instantly conveyed to the feeding mechanism through the hopper, the material is easily overlapped or piled up on the feeding mechanism, and the feeding mechanism has poor material conveying stability, and the material cannot be dispersed, resulting in the counting device being unable to calculate the quantity of the material output by the feeding mechanism, thereby being unable to accurately quantitatively feed the material. The method first disperses and spreads the material Transport and feed through dual channels, one side of the dual channels is for large-scale rapid feeding, and the other side is for small-scale slow feeding. When the large-scale feeding reaches the specified amount, the slow and small-scale feeding is carried out, and the material quantity is calculated through the counting device, which can accurately and quantitatively output the material. However, during the overall operation, the amount of material transported by the dual channels is constant. When the feeding amount is about to reach the specified amount, the feeding amount in the slow feeding channel is still the specified amount. In the case of a small difference, the material remaining in the slow feeding channel will continue to enter the subsequent feeding process. Summary of the invention

DETAILED DESCRIPTION

[0031] 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.

[0032] Embodiment 1: Figure 1As shown, the present application discloses an automatic feeding device with adjustable feeding amount of a hopper content, comprising a first discharge bin 100, the first discharge bin 100 is connected to a feeding hopper 101, the discharge port of the first discharge bin 100 is connected to a second discharge bin 102, an upper cover plate 103 is hingedly connected to the second discharge bin 102, a side of the upper cover plate 103 close to the inside of the second discharge bin 102 is installed with a vertically extending air bag 107 through an adjusting structure, both sides of the vertically extending air bag 107 are fixedly connected to side partition plates 108, and a bidirectional air pump 104 is fixedly connected to the upper cover plate 103. The air outlet of the two-way air pump 104 is connected with an air hose 106. A placement slot 105 is provided on the outside of the upper cover plate 103. The air outlet of the air hose 106 passes through the placement slot 105 and is connected with a vertical extension airbag 107. The vertical extension airbag 107 is used for the gas to continuously enter the vertical extension airbag 107 to expand during the process of the two-way air pump 104 injecting gas into the vertical extension airbag 107, thereby driving the side partition plate 108 to separate the internal space of the second discharge bin 102 into a fine feeding space and a fast feeding space;

[0033] Specifically, during use, the staff puts a large amount of material into the feed hopper 101. After the material is put into the feed hopper 101, the material will enter the first discharge bin 100 by gravity. When the material enters the first discharge bin 100, it will gradually flow to the second discharge bin 102 by gravity. When the material flows to the second discharge bin 102 following gravity, the staff can start the two-way air pump 104 to continuously inject gas into the gas hose 106. When the gas is injected into the gas hose 106, it will gradually be transported to the interior of the vertical extension airbag 107. When the inner wall of the vertical extension airbag 107 gradually enters the gas, the vertical extension airbag 107 will gradually produce When the vertically extending airbag 107 gradually expands, it will drive the side partition 108 to move downward, thereby occupying the space inside the second discharge bin 102, and at the same time dividing the space inside the second discharge bin 102. When dividing the space inside the second discharge bin 102, the space inside the second discharge bin 102 is divided into a fine feeding space and a fast feeding space. When dividing the fine feeding space and the fast feeding space, the staff can use the adjustment structure to move the position of the side partition 108 and the vertically extending airbag 107 according to the situation, so as to adjustably allocate the space occupancy of the fine feeding space and the fast feeding space inside the second discharge bin 102 when the vertically extending airbag 107 is extended.

[0034] like Figure 1-Figure 3As shown, the adjustment structure includes two movable grooves 109, and the two movable grooves 109 are opened on the outside of the upper cover plate 103. Two adjusting screws 110 are rotatably connected to the vertically extending airbag 107. The two adjusting screws 110 are respectively slidably connected to the inside of the movable grooves 109, and the external threads of the adjusting screws 110 are connected to the adjusting bolts 111.

[0035] Specifically, in the adjustment structure, when the staff needs to adjust the proportion of the fine feeding space and the fast feeding space occupied by the internal space of the second discharge bin 102, the user can rotate the adjusting bolt 111 upwards to separate the adjusting bolt 111 from the upper cover plate 103. After the adjusting bolt 111 is separated from the upper cover plate 103, the staff can horizontally adjust the position of the vertical extension airbag 107 and the side partition 108 inside the placement slot 105. After adjusting the vertical extension airbag 107 and the side partition 108 to the specified position, when the vertical extension airbag 107 is inflated again, the vertical extension airbag 107 and the side partition 108 can separate the internal space of the second discharge bin 102 at the specified position, thereby realizing the free adjustment of the fine feeding space and the fast feeding space, which is convenient for free adjustment according to feeding needs.

[0036] Furthermore, when the vertically extending airbag 107 and the side partition 108 are arranged on the upper cover plate 103, when continuous feeding is required, the staff can no longer continuously inject gas into the interior of the vertically extending airbag 107, so that the vertically extending airbag 107 and the side partition 108 no longer separate and block the internal space of the second discharge bin 102, thereby reducing the obstruction of the internal space of the second discharge bin 102 and realizing continuous and rapid feeding.

[0037] like Figure 1-Figure 2 As shown, a sweeping roller 701 is rotatably connected to the side wall of the discharge port of the first discharge bin 100 , and a driving motor 700 is fixedly connected to the outside of the first discharge bin 100 . The output shaft of the driving motor 700 passes through the outer wall of the first discharge bin 100 and is fixedly connected to the sweeping roller 701 .

[0038] Specifically, during use, when the material is continuously transported inside the first discharge bin 100, the drive motor 700 is started to rotate. The drive motor 700 can drive the sweeping roller 701 to rotate while rotating. The sweeping roller 701 can evenly block the material at the discharge port of the first discharge bin 100 during the rotation, and evenly spread the transported material to the bottom of the second discharge bin 102, so as to ensure the uniformity of material transportation.

[0039] like Figure 1 As shown, buckles 800 are installed on the second discharge bin 102 and the upper cover plate 103 .

[0040] Specifically, through the setting of the buckle 800, the staff can hang a lock on the buckle 800, and lock the upper cover 103 and the second discharge bin 102 through the buckle 800. At the same time, after opening the buckle 800, the staff can open the upper cover 103 to inspect the interior of the second discharge bin 102 and the vertically extending airbag 107 and the side partition 108.

[0041] like Fig.10 As shown, a sliding groove (not shown in the figure) is provided on the outlet side of the second discharge bin 102, a baffle 602 is slidably connected inside the sliding groove, a plurality of tooth grooves 603 are provided on the side wall of the baffle 602, micro motors 600 are fixedly connected on both sides of the second discharge bin 102, and a gear 601 is fixedly connected to the output shaft of the micro motor 600, and the gear 601 is meshingly connected with the tooth groove 603.

[0042] Specifically, when the material is transported, the staff can start the micro motor 600 to drive the gear 601 to rotate. When the gear 601 is rotating, it can cooperate with the meshing gear 601 to drive the baffle 602 to move up and down. When the baffle 602 moves to the discharge port position of the second discharge bin 102, the discharge port of the second discharge bin 102 can be completely closed.

[0043] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, through the arrangement of the vertically extending airbag 107 and the side partition 108, when the material needs to be finely fed, gas is injected into the interior of the vertically extending airbag 107, and while continuously injecting gas into the interior of the vertically extending airbag 107, the vertically extending airbag 107 can be extended to drive the side partition 108 to separate the space inside the second discharge bin 102, thereby separating the fine feeding space and the fast feeding space, and the space ratio occupied by the fine feeding space and the fast feeding space can be freely adjusted through the arrangement of the adjustment structure, so that the staff can freely adjust the fast feeding amount and the fine feeding amount according to the situation.

[0044] Embodiment 2: Considering that during use, during the continuous feeding process, when the material is about to reach the specified material amount, although it can be slowly finely fed through the fine feeding space, the fine feeding space is also continuously fed, and the feeding amount cannot be further reduced, and after reaching the specified feeding amount, it cannot block the continued transportation of the material in the internal space of the second discharge bin 102. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0045] like Figure 5-Figure 6As shown, two transverse extension airbags 200 are integrally formed inside the vertical extension airbag 107, and the two transverse extension airbags 200 are connected with a telescopic hose 202. The end of the telescopic hose 202 away from the transverse extension airbag 200 is connected with an electrically controlled multi-way connecting valve 201, and the air outlet of the air supply hose 106 is connected to the electrically controlled multi-way connecting valve 201. The two transverse extension airbags 200 are used to further adjust the position of the side partition 108 during the process of dividing the internal space of the second discharge bin 102 by the side partition 108, thereby adjusting the feeding speed and feeding amount of the fine feeding space and the fast feeding space.

[0046] Specifically, during use, when the material is being continuously conveyed and the material conveying is about to reach a specified quantity or a specified weight, the two-way air pump 104 is continuously started to convey the gas to the inside of the electrically controlled multi-way connecting valve 201. After the gas is conveyed to the inside of the electrically controlled multi-way connecting valve 201, the electrically controlled multi-way connecting valve 201 will convey the gas to the inside of the telescopic hose 202, and the gas is conveyed to the inside of the two laterally extending airbags 200 through the two telescopic hoses 202. When the gas is conveyed to the inside of the two laterally extending airbags 200, the lateral extension of the gasbags 200 can be made. The horizontal extension airbag 200 expands horizontally. When the horizontal extension airbag 200 expands horizontally, the vertical extension airbag 107 can be extended and the side partition 108 can be displaced by the horizontal extension airbag 200. When the side partition 108 cooperates with the horizontally extending vertical extension airbag 107 and the horizontal extension airbag 200 to extend, the internal space of the second discharge bin 102 can be further occupied, thereby making a secondary adjustment to the space ratio of the fine feeding space and the fast feeding space.

[0047] Furthermore, when the material conveying is about to reach the specified weight, the gas is diverted to the interior of one of the transversely extending airbags 200 through the electrically controlled multi-way connecting valve 201, so that one of the transversely extending airbags 200 quickly expands laterally until one of the transversely extending airbags 200 drives one side partition 108 to fit the interior of the second discharge bin 102, thereby completely closing the rapid feeding space. At the same time, when the rapid feeding space is completely closed, the fine feeding space is still continuously conveying materials, and the amount of conveyed materials is gradually approaching. In the process, the gas is diverted to another transversely extending airbag 200 through the electrically controlled multi-way connecting valve 201, and the other transversely extending airbag 200 also gradually expands. The expansion method is slow expansion. Under the condition of slow expansion, the conveyable channel of the fine feeding space can be gradually reduced, thereby further gradually reducing the material conveying and further enhancing the accuracy of material conveying.

[0048] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in this embodiment, in the process of conveying materials, when the specified amount of material conveying is about to be reached, gas can be conveyed to the inside of the two laterally extending airbags 200 respectively. When gas is conveyed to the inside of the two laterally extending airbags 200 respectively, one of the laterally extending airbags 200 can completely block the fast feeding space, and the other laterally extending airbag 200 can gradually block the fine feeding space. When the fine feeding space is gradually blocked, the feed amount can be further gradually reduced, thereby further improving the accuracy of material conveying.

[0049] Embodiment 3: Considering that when the transversely extending airbag 200 drives the side baffle 108 to gradually block the fine feed space, the side baffle 108 during the movement will gradually push the material in the fine feed space. In this case, part of the material will be gradually pushed together. As the materials are gradually pushed together and the fine feed space is gradually reduced, the materials may be squeezed together to cause a blockage. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0050] like Figure 7 As shown, the laterally extending airbag 200 is a double-layer bag body, which is divided into an inner bag and an outer bag, and an air intake space is formed between the inner bag and the outer bag. The air outlet of the telescopic hose 202 is a double-headed port, one end of which is connected to the air intake space, and the other end is connected to the inner bag. A plurality of supporting springs 300 are fixedly connected to the interior of the inner bag, and a shaking ball 301 is movably connected to one end of the supporting spring 300 away from the inner bag, and a jet pipe 302 is integrally formed on the outside of the inner bag and the air intake space.

[0051] Specifically, during use, when gas is transported to the inside of the transversely extending airbag 200 through the telescopic hose 202, the double-ended ports of the telescopic hose 202 will transport gas to the inside of the inner bag and the air intake space respectively. When the air intake space expands, the transversely extending airbag 200 can provide more stable support. At the same time, when the gas continues to enter the inside of the inner bag, it can also support the transversely extending airbag 200 as a whole. When the continuously expanding transversely extending airbag 200 continues to push the side partition 108 to squeeze the material, the jet located outside the inner bag and the air intake space The tube 302 can continuously blow the gas in the inner bag and the air intake space to the outside, thereby accelerating the movement speed of the material and reducing the accumulation phenomenon. At the same time, in the process of gas blowing, the continuously blown gas will blow the shaking ball 301 to cooperate with the support spring 300 to produce shaking inside the inner bag. When the shaking ball 301 cooperates with the support spring 300 to continuously shake, it will knock on the side wall of the side partition 108 and the bottom wall of the second discharge bin 102, and generate a certain vibration through continuous knocking, thereby shaking off the accumulated material through vibration, further reducing the phenomenon of material accumulation.

[0052] Furthermore, the pitches of the support springs 300 are not uniform, and the pitches of the multiple support springs 300 are not the same. The multiple support springs 300 with different pitches can drive the shaking ball 301 to generate different vibration amplitudes at different positions, thereby enhancing the overall vibration effect.

[0053] Furthermore, the amount of gas blown out by the gas jet pipe 302 is much smaller than the amount of gas injected into the inner bag and the air intake space by the telescopic hose 202, so the overall instability will not be caused by the blowing of gas during use.

[0054] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment 2, in this embodiment, when the side partition 108 pushes the material during the gradual movement process and causes the material to be blocked in the gradually shrinking channel, the gas is continuously blown out through the jet pipe 302 to accelerate the circulation of the material and reduce the extrusion blockage of the material. At the same time, when the material has been extruded and blocked, the continuously blown gas can also blow the shaking ball 301 to continuously shake inside the inner capsule, so that multiple shaking balls 301 cooperate with the support spring 300 to continuously hit the side partition 108 and the inner bottom wall of the second discharge bin 102, thereby generating continuous vibration, and the accumulated material is shaken away when the continuous vibration is generated, avoiding the side partition 108 causing material extrusion and blockage when the feeding channel is gradually narrowed.

[0055] Embodiment 4: Considering that when the gas is continuously blown, the shaking ball 301 may always tilt in one direction without generating a large vibration. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0056] like Figure 8 As shown, an inner groove 400 is provided on the outside of the shaking ball 301, and the shaking ball 301 and the supporting spring 300 are rotatably connected via a rotating shaft.

[0057] Specifically, during use, when gas is blown to the outside of the shaking ball 301, the concave surface of the inner groove 400 can form a force-bearing surface. When the inner groove 400 is under force, it will drive the shaking ball 301 to rotate on the support spring 300 through the rotating shaft, and the inner wall connecting the support spring 300 and the laterally extending airbag 200 is soft. Once part of the shaking ball 301 produces rotation and shaking, the direction of the airflow blown out from the port of the telescopic hose 202 will change. If the airflow changes randomly, it will cause the airflow to blow to the outside of different shaking balls 301, causing different shaking balls 301 to produce shaking of different amplitudes, and when the shaking ball 301 rotates again, its shaking amplitude will be further enhanced. When the shaking amplitude increases, the vibration generated inside the laterally extending airbag 200 as a whole will be further enhanced, thereby avoiding the phenomenon that the shaking ball 301 always tilts in one direction when the airflow is constant.

[0058] like Fig. 9 As shown, a storage cavity is provided inside the shaking ball 301 , and the storage cavity is filled with filling water 500 .

[0059] Specifically, a storage cavity is opened inside the shaking ball 301, and filling water 500 is injected into the storage cavity. Through the setting of the filling water 500, during the rotation of the shaking ball 301, the filling water 500 shakes inside the storage cavity, thereby further enhancing the overall shaking amplitude of the shaking ball 301, and further enhancing the impact force of multiple shaking balls 301 on the inner bottom wall of the second discharge bin 102 and the side wall of the side partition 108, thereby enhancing the vibration amplitude.

[0060] Furthermore, multiple shaking balls 301 are staggered, and some of the shaking balls 301 are parallel to the positions of the jet tubes 302. When some of the shaking balls 301 are parallel to the positions of the jet tubes 302, the blown gas can be blown specifically to the inner groove 400 outside the shaking ball 301, so that the inner groove 400 is subjected to force to drive the shaking ball 301 to rotate.

[0061] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: relative to embodiment three, in the present embodiment, through the setting of the inner groove 400, the blown gas can contact the inner concave surface of the inner groove 400 during the process of gas blowing, so that the gas pushes the shaking ball 301 to shake, and when the gas blows the shaking ball 301, it can also drive the shaking ball 301 to rotate. When the shaking ball 301 rotates, the shaking amplitude of the shaking ball 301 can be further enhanced. By further enhancing the shaking amplitude of the shaking ball 301, the knocking force of multiple shaking balls 301 on the inner bottom wall of the second discharge bin 102 and the side wall of the side partition 108 is enhanced, the vibration amplitude is enhanced, and the vibration effect is further enhanced.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
