Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent conveying equipment for agricultural products, and particularly relates to a bidirectional hatch automatic-switching storage tank for agricultural product conveying. Background Art

[0002] During the current storage process of storage tanks, the problem of uneven temperature and humidity distribution inside the grain pile has long existed. Due to the self-respiration of grains and the conduction of the external environment, a microenvironment with heat accumulation and excessive humidity is likely to form in the middle area of the storage tank. The grains in this area are prone to mildew, germination and other deterioration phenomena during long-term storage, resulting in economic losses.

[0003] Most of the existing storage tank discharging devices adopt a bottom gravity discharging or top suction structure, and can only achieve grain taking in a single direction. Although some improved schemes add multiple discharging ports, they lack the linkage control with the grain condition monitoring system and still require manual judgment and operation. Such designs cannot dynamically adjust the taking position and sequence according to the actual situation inside the grain pile, resulting in difficulty in timely and preferentially taking out the grains in high-risk areas.

[0004] Therefore, it is very necessary to study a bidirectional hatch automatic-switching storage tank for agricultural product conveying with the ability of layered directional taking based on grain pile state detection. Specifically, it is necessary to realize the multi-directional switching of the taking channel, the real-time linkage of the hatch opening and closing and the detection data, so as to accurately extract the grains in the easily deteriorated parts. Summary of the Invention

[0005] In view of the above deficiencies in the prior art, the present invention provides a bidirectional hatch automatic-switching storage tank for agricultural product conveying to solve the problem that the prior art cannot dynamically adjust the taking position and sequence according to the actual situation inside the grain pile.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A bidirectional hatch automatic-switching storage tank for agricultural product conveying, comprising: a tank body, a conveying valve, a combined taking pipe, a driving mechanism and a detection mechanism;

[0008] The tank body is provided with a grain storage port and a discharging port;

[0009] The conveying valve includes a valve body and a baffle. The valve body is a hollow shell with upper and lower openings. A third feeding port is provided on the upper end face of the valve body. The baffle is rotatably arranged in the valve body. A fourth hole is provided on the baffle. The materials at the bottom of the tank body enter the valve body through the third feeding port and the fourth hole;

[0010] The combined material extraction pipe includes a first material extraction pipe, a second material extraction pipe, and a third material extraction pipe. The first material extraction pipe is fixedly connected to the upper opening of the valve body. The second material extraction pipe is rotatably arranged inside the first material extraction pipe, and the third material extraction pipe is rotatably arranged inside the second material extraction pipe. The first material extraction pipe is provided with a first feed port and a second feed port. The second material extraction pipe is provided with a first hole corresponding to the position of the first material extraction pipe and a second hole corresponding to the position of the second feed port. The third material extraction pipe is provided with a third hole corresponding to the position of the second feed port. The opening and closing of the first feed port and the second feed port on the first material extraction pipe are controlled by the rotation of the second material extraction pipe and the third material extraction pipe.

[0011] The driving mechanism is installed on the valve body, and the driving mechanism is connected to the second material extraction pipe, the third material extraction pipe, and the baffle.

[0012] The detection mechanism is used to detect the height of the material in the tank.

[0013] Furthermore, the conveying valve further includes a flap and a telescopic rod. The flap is hinged to the lower opening of the valve body. One end of the telescopic rod is hinged to the flap, and the other end is hinged to the valve body.

[0014] Furthermore, a first pulley is provided on the outer wall of the lower end of the second material extraction pipe.

[0015] Even further, a second pulley is provided on the outer wall of the lower end of the third material extraction pipe.

[0016] Even further, the driving mechanism includes a second driving motor, a third pulley, a first one-way bearing, a fourth pulley, and a second one-way bearing. The second driving motor is fixedly connected to the valve body. The third pulley is installed on the rotating shaft of the second driving motor through the first one-way bearing. The third pulley is connected to the first pulley through a belt. The fourth pulley is installed on the rotating shaft of the second driving motor through the second one-way bearing. The fourth pulley is connected to the second pulley through a belt.

[0017] Even further, the rotation directions of the first one-way bearing and the second one-way bearing are opposite.

[0018] Furthermore, the driving mechanism further includes a first driving motor. The first driving motor is fixedly connected to the valve body, and the first driving motor is connected to the baffle.

[0019] Furthermore, the detection mechanism includes a grating emitter and a grating receiver. The grating emitter is fixedly connected to the outer wall of the first material extraction pipe, and the grating receiver is fixedly connected to the inner wall of the tank. The grating emitter and the grating receiver cooperate with each other.

[0020] Even further, the detection mechanism further includes a distance measuring sensor. The distance measuring sensor is fixedly connected to the outer wall of the first material extraction pipe.

[0021] Furthermore, the ranging sensor is arranged to incline downward by 15 - 45 degrees.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. For an automatic - switch storage tank with a two - way bin door for agricultural product transportation disclosed by the present invention, through the cooperation of the multi - layer rotating structure of the combined material - taking pipe and the conveying valve, the hierarchical and directional material taking of high - level, middle - level, and low - level materials in the tank is realized. The middle - layer or high - level grains that are prone to heat - accumulation and deterioration are preferentially extracted, achieving dynamic adjustment of the material - taking position and sequence, and breaking through the limitation of the single - direction discharging of traditional storage tanks.

[0024] 2. For an automatic - switch storage tank with a two - way bin door for agricultural product transportation disclosed by the present invention, based on the linkage design of the two - way driving mechanism and the one - way bearing, only a single second driving motor is required to independently control the forward and reverse rotation of the second material - taking pipe and the third material - taking pipe. Through the detection of the grating sensor and the ranging sensor, the height difference of the materials between the inner wall and the central area of the tank can be accurately judged, and then the opening and closing operations of the corresponding feeding ports are triggered. Without the need to add an additional power source, this solution significantly improves the response speed of the material - taking position switching, while reducing the equipment complexity and energy consumption.

[0034] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] In the description of the present application, it should be noted that for orientation terms, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationships are based on the orientation or position relationships shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0037] Please refer to Figures 1 to 7 As shown, a two-way bin door automatic switch storage tank for agricultural product transportation includes: a tank body 1 for storing grains, a conveyor valve 2 and a combined material taking pipe 3 for dynamically adjusting the material taking position and sequence, a driving mechanism 4 for driving the conveyor valve 2 and the combined material taking pipe 3 to work, and a detection mechanism for detecting the height of grains in the tank body 1.

[0038] The tank body 1 is provided with a grain storage opening 11 and a discharge opening 12.

[0039] The delivery valve 2 includes a valve body 21 and a baffle 23. The valve body 21 is a hollow shell with upper and lower openings, and a third feed port 22 is arranged on the upper end surface of the valve body 21. The baffle 23 is rotatably arranged in the valve body 21, and a fourth hole 231 is arranged on the baffle 23. It can be understood that the driving mechanism 4 drives the baffle 23 to rotate in the valve body 21, and when the third feed port 22 coincides with the fourth hole 231, the material at the bottom of the tank body 1 enters the valve body 21 through the third feed port 22 and the fourth hole 231; when the third feed port 22 and the fourth hole 231 are staggered, the material cannot enter the valve body 21 through the third feed port 22 and the fourth hole 231. Specifically, the delivery valve 2 also includes a flap 24 and a telescopic rod 25. The flap 24 is hinged at the lower end opening of the valve body 21. One end of the telescopic rod 25 is hinged to the flap 24, and the other end is hinged to the valve body 21. It can be understood that the shortening of the telescopic rod 25 can drive the flap 24 to flip upward, so as to open the lower end opening of the valve body 21, and the material in the valve body 21 is discharged from the lower end opening of the valve body 21. The extension of the telescopic rod 25 drives the flap 24 to flip downward, so as to close the lower end opening of the valve body 21.

[0040] The combined material taking pipe 3 includes a first material taking pipe 31, a second material taking pipe 32 and a third material taking pipe 33. The first material taking pipe 31 is fixedly connected to the upper end opening of the valve body 21, the second material taking pipe 32 is rotatably arranged in the first material taking pipe 31, and the third material taking pipe 33 is rotatably arranged in the second material taking pipe 32.

[0041] The first feeding tube 31 is provided with a first feeding port 311 and a second feeding port 312. The second feeding tube 32 is provided with a first hole 321 corresponding to the position of the first feeding tube 31 and a second hole 322 corresponding to the position of the second feeding port 312. It should be noted that during the rotation of the second feeding tube 32, the second holes 322 are at least partially aligned with the second feeding port 312. Specifically, there are multiple second holes 322, and the multiple second holes 322 are evenly arranged on the outer wall of the second feeding tube 32 along the axial direction of the second feeding tube 32. When the second feeding tube 32 rotates, at least one part of the second hole 322 is aligned with the second feeding port 312, which does not affect the passage of materials through the second feeding port 312 and the second hole 322. It can be understood that when the second feeding pipe 32 rotates in the first feeding pipe 31 and the first feeding port 311 is at least partially aligned with the first hole 321, the material at the upper end of the tank body 1 can enter the combined feeding pipe 3 through the first feeding port 311 and the first hole 321, and then enter the valve body 21 through the combined feeding pipe 3; when the first feeding port 311 and the first hole 321 are completely staggered, the material cannot enter the combined feeding pipe 3 through the first feeding port 311 and the first hole 321.

[0042] A third material extraction pipe 33 is provided with a third hole 331 corresponding to the position of the second feed inlet 312. It can be understood that as the third material extraction pipe 33 rotates in the second material extraction pipe 32, when at least a part of the third hole 331 is aligned with the second material extraction pipe 32, the material in the middle of the tank body 1 enters the combined material extraction pipe 3 through the second feed inlet 312, the second hole 322, and the third hole 331. When the third hole 331 is completely staggered from the second feed inlet 312, the material cannot enter the combined material extraction pipe 3 through the third hole 331.

[0043] The rotation of the second material extraction pipe 32 and the third material extraction pipe 33 controls the opening and closing of the first feed inlet 311 and the second feed inlet 312 on the first material extraction pipe 31.

[0044] Specifically, a first pulley 323 is provided on the outer wall of the lower end of the second material extraction pipe 32, and a second pulley 332 is provided on the outer wall of the lower end of the third material extraction pipe 33.

[0045] The drive mechanism 4 is installed on the valve body 21, and the drive mechanism 4 is connected to the second material extraction pipe 32, the third material extraction pipe 33, and the baffle 23. Specifically, the drive mechanism 4 further includes a first drive motor 41. The first drive motor 41 is fixedly connected to the valve body 21, and the first drive motor 41 is connected to the baffle 23, that is, the first drive motor 41 can drive the baffle 23 to rotate in the valve body 21.

[0046] The drive mechanism 4 includes a second drive motor 42, a third pulley 43, a first one-way bearing 44, a fourth pulley 45, and a second one-way bearing 46. The second drive motor 42 is fixedly connected to the valve body 21. The third pulley 43 is installed on the rotating shaft of the second drive motor 42 through the first one-way bearing 44. The third pulley 43 is connected to the first pulley 323 through a belt. The fourth pulley 45 is installed on the rotating shaft of the second drive motor 42 through the second one-way bearing 46. The fourth pulley 45 is connected to the second pulley 332 through a belt. It should be noted that the rotation directions of the first one-way bearing 44 and the second one-way bearing 46 are opposite. It can be understood that when the second drive motor 42 rotates forward, the second drive motor 42 can drive the third pulley 43 to rotate through the first one-way bearing 44, and then drive the second material extraction pipe 32 to rotate through the belt and the first pulley 323, while the second one-way bearing 46 is in an idling state and cannot drive the fourth pulley 45 to rotate through the second one-way bearing 46. When the second drive motor 42 rotates in reverse, the second drive motor 42 can drive the fourth pulley 45 to rotate through the second one-way bearing 46, and then drive the third material extraction pipe 33 to rotate through the belt and the second pulley 332, while the first one-way bearing 44 is in an idling state and cannot drive the third pulley 43 to rotate through the first one-way bearing 44.

[0047] The detection mechanism is used to detect the height of the material in the tank body 1. Specifically, the detection mechanism includes a grating emitter 51 and a grating receiver 52. The grating emitter 51 is fixedly connected to the outer wall of the first material extraction pipe 31, and the grating receiver 52 is fixedly connected to the inner wall of the tank body 1. The grating emitter 51 and the grating receiver 52 cooperate. It should be noted that when the material is discharged, the material close to the conveying valve 2 and the combined material extraction pipe 3 is discharged first, that is, the material in the middle part of the tank body 1 is discharged first. At this time, the height of the material in the middle part is lower, while the height of the material close to the inner wall of the tank body 1 is higher. It can be understood that the grating emitter 51 and the grating receiver 52 can determine the height of the material at the position close to the inner wall of the tank body 1, which is convenient for the user to judge the storage situation of the material in the tank body 1, and then determine the material extraction position. When the material is discharged from high to low, the material extraction position can also be determined according to the height of the material, and then the first feed port 311, the second feed port 312, and the third feed port 22 are opened in sequence.

[0048] The detection mechanism further includes a distance measuring sensor 53, and the distance measuring sensor 53 is fixedly connected to the outer wall of the first material extraction pipe 31. Correspondingly, the distance measuring sensor 53 is arranged to incline downward by 15-45 degrees. It can be understood that the distance measuring sensor 53 can detect the height of the material in the middle part of the tank body 1. By the cooperation of the grating emitter 51, the grating receiver 52 and the distance measuring sensor 53, the height of the material in the tank body 1 can be accurately determined.

[0049] The working principle of the present invention is as follows:

[0050] When discharging the high-position material in the tank body 1:

[0051] The second driving motor 42 of the driving mechanism 4 drives the second material extraction pipe 32 and the third material extraction pipe 33 to rotate through forward and reverse rotation; until at least part of the first hole 321 on the second material extraction pipe 32 is aligned with the first feed port 311, and the third hole 331 is completely staggered from the second feed port 312; the first driving motor 41 drives the baffle 23 to rotate until the fourth hole 231 is completely staggered from the third feed port 22; the telescopic rod 25 shortens to drive the flap 24 to turn upward, and the lower end opening of the valve body 21 can be opened; the high-position material in the tank body 1 enters the combined material extraction pipe 3 through the first feed port 311 and the first hole 321, then enters the valve body 21, and is then discharged from the lower end opening of the valve body 21.

[0052] When discharging the middle-position material in the tank body 1:

[0053] The second drive motor 42 of the drive mechanism 4 drives the second material extraction pipe 32 and the third material extraction pipe 33 to rotate through forward and reverse rotation; until the first hole 321 of the second material extraction pipe 32 is completely staggered from the first feed port 311, and at least a part of the third hole 331 of the third material extraction pipe 33 is aligned with the second material extraction pipe 32; the first drive motor 41 drives the baffle 23 to rotate until the fourth hole 231 is completely staggered from the third feed port 22; the telescopic rod 25 shortens to drive the flap 24 to turn upwards, opening the lower end opening of the valve body 21; the middle-position material in the tank body 1 enters the combined material extraction pipe 3 through the first feed port 311 and the first hole 321, then enters the valve body 21, and is discharged from the lower end opening of the valve body 21.

[0054] When discharging the low-position material in the tank body 1:

[0055] The second drive motor 42 of the drive mechanism 4 drives the second material extraction pipe 32 and the third material extraction pipe 33 to rotate through forward and reverse rotation; until the first hole 321 of the second material extraction pipe 32 is completely staggered from the first feed port 311, and the third hole 331 of the third material extraction pipe 33 is completely staggered from the second material extraction pipe 32; the first drive motor 41 drives the baffle 23 to rotate until at least a part of the fourth hole 231 is aligned with the third feed port 22; the telescopic rod 25 shortens to drive the flap 24 to turn upwards, opening the lower end opening of the valve body 21; the low-position material in the tank body 1 enters the combined material extraction pipe 3 through the first feed port 311 and the first hole 321, then enters the valve body 21, and is discharged from the lower end opening of the valve body 21, and at this time, the material in the tank body 1 can be completely emptied.

[0056] When discharging materials in the order of high position - middle position - low position:

[0057] The detection mechanism is started to detect the height of the material in the tank body 1 in real time; the high-position material in the tank body 1 is preferentially discharged until the material height drops below the first feed port 311; the high-position material in the tank body 1 starts to be discharged until the material height drops below the second feed port 312; the low-position material in the tank body 1 starts to be discharged until the material in the tank body 1 is completely emptied.
