Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain dryer is with distributing valve, especially to a kind of grain dryer is with distributing valve. BACKGROUND

[0002] Grain dryer is with distributing valve is important component for controlling grain flow and distribution in grain drying process.The common three-way distributing valve generally has one input end and two output ends,which can distribute grain transported from hoist and other equipment to different feed inlet or different drying channel of dryer as required,for example, pneumatic three-way distributing valve, which realizes the switching of grain flow by driving device such as air cylinder to control internal swing assembly. Taking the common swing type three-way distributing valve as an example, it is mainly composed of valve body, valve shaft, valve plate, crank mechanism and driving device (such as electric push rod, electro-hydraulic push rod, pneumatic push rod or manual mechanism). When working, the driving device produces linear reciprocating motion, which drives the valve shaft and valve plate to swing at a certain angle, thereby changing the opening and closing state of the material channel to achieve the purpose of controlling grain flow and distributing grain.

[0003] The patent with publication number CN219062521U discloses a pneumatic three-way distributing valve and grain dryer, the pneumatic three-way distributing valve includes a valve body, including an input end and a first output end and a second output end; a swing assembly is movably arranged and has a first station and a second station, which cuts off the first output end when in the first station and cuts off the second output end when in the second station; a driving assembly is detachably connected with the swing assembly for driving the swing assembly to switch; a switching assembly is connected with the swing assembly; when the driving assembly is fixedly connected with the swing assembly, the switching assembly moves synchronously with the swing assembly; when the driving assembly is relatively separated from the swing assembly, the switching assembly is suitable for driving the swing assembly to move.

[0004] In the above-mentioned scheme, the swing assembly, i.e. valve plate, takes relatively long time to switch between the two positions under the driving of the driving assembly, and part of the grain may fall into the two output ends at the same time, which cannot meet the needs of accurate distribution and reduces the applicability. UTILITY MODEL CONTENTS

[0005] In view of the problem that the swing assembly, i.e. valve plate, takes relatively long time to switch between the two positions under the driving of the driving assembly, and part of the grain may fall into the two output ends at the same time, which cannot meet the needs of accurate distribution and reduces the applicability, the utility model provides a grain dryer distributing valve.

[0006] To solve the above-mentioned problem, the utility model adopts the technical scheme that,

[0007] A dispensing valve for a grain dryer includes a housing with an input end, a first output end, and a second output end. A valve plate is rotatably mounted inside the housing, movable from a first position (cut off at the first output end) to a second position (cut off at the second output end). The valve plate is connected to a drive mechanism, and its bottom surface is hinged to the housing. The hinge point between the valve plate and the housing is located on the center line of the input end and in the middle of the housing. A funnel is fixedly mounted inside the input end in conjunction with the valve plate. The hinged position of the valve plate's bottom surface to the housing, located on the center line of the input end and in the middle of the housing, combined with the funnel fixed inside the input end, allows the grain to be guided more concentratedly and evenly to the valve plate during input, effectively improving the accuracy and stability of dispensing. This reduces the simultaneous falling of grain into the first and second output ends during the valve plate's transition from the first to the second position, making it suitable for applications requiring precise dispensing and increasing its applicability.

[0008] Preferably, the valve plate includes a base plate; side plates are fixedly arranged on both sides along the length of the base plate; the space enclosed by the base plate and the two side plates faces the input end; a hinge shaft is installed in the middle of the bottom surface of the base plate; the hinge shaft is hinged to the housing. The reasonable arrangement of the valve plate can effectively receive and guide the grain flow. The hinge shaft installed in the middle of the bottom surface of the base plate is hinged to the housing, and in conjunction with the valve plate and drive mechanism rotatably arranged inside the housing, it can precisely control the grain flow direction and stop different output ends. Simultaneously, the valve plate, hinged to the housing in the middle of its bottom surface and located on the center line of the input end and in the middle of the housing, works in conjunction with the funnel fixedly arranged inside the input end, making the grain input more concentrated and evenly guided to the valve plate, greatly improving the accuracy and stability of material distribution, and further reducing the amount of grain falling into the first and second output ends simultaneously.

[0009] Preferably, the funnel is configured as a frustum-shaped shell; the perpendicular distance from the center line of the hinge shaft to the bottom surface of the funnel is less than half the width of the bottom plate. The frustum-shaped shell of the funnel facilitates smooth and concentrated flow of grain towards the valve plate. Its unique shape effectively prevents grain from accumulating or spilling at the input end, optimizing the grain conveying path. The design that the perpendicular distance from the center line of the hinge shaft to the bottom surface of the funnel is less than half the width of the bottom plate allows for more efficient distribution of grain to different output ends during valve plate rotation. This reasonable distance ensures more precise control of the grain flow direction by the valve plate, further reducing the amount of grain falling into both the first and second output ends simultaneously, thus ensuring efficient and stable operation of the grain dryer under various working conditions.

[0010] Preferably, a limiting plate is fixedly installed inside the housing; the limiting plate is positioned in conjunction with the first and second positions of the valve plate. The limiting plate fixedly installed inside the housing cooperates with the first and second positions of the valve plate, which can effectively limit the rotation range of the valve plate, avoid excessive rotation that may cause positional deviation, further ensure the accuracy of the valve plate position during the material distribution process, and increase the applicability of the material distribution valve for the grain dryer.

[0011] Preferably, a U-shaped mounting frame is fixedly installed in the center of the bottom surface of the base plate; the hinge shaft is detachably mounted within the mounting frame. The U-shaped mounting frame fixed in the center of the bottom surface of the base plate provides a stable and suitable mounting foundation for the hinge shaft, making its installation more convenient and secure. The detachable mounting of the hinge shaft within the mounting frame greatly improves the ease of maintenance of the distributing valve. When the hinge shaft experiences wear or malfunction, there is no need for large-scale disassembly and replacement of the entire valve plate or distributing valve. Maintenance personnel can easily remove the hinge shaft from the mounting frame for repair or replacement, effectively shortening maintenance time, reducing maintenance costs, ensuring the long-term stable operation of the grain dryer's distributing valve, and ensuring the continuity and efficiency of the drying operation.

[0012] Preferably, the mounting frame has a through hole; the through hole penetrates the base plate; and the hinge shaft has a radial hole that mates with the through hole. The through hole in the mounting frame, penetrating the base plate, works in conjunction with the radial hole on the hinge shaft to facilitate assembly, maintenance, and operation. During use, it allows installers to easily use bolts to position and fix the hinge shaft within the mounting frame, improving assembly efficiency and accuracy.

[0013] Preferably, a frustum is provided at the end of the hinge shaft after it passes through the housing. This facilitates connection to an external drive device.

[0014] Preferably, a swing plate is fixedly installed on the hinge shaft near its edge; the swing plate is positioned in the middle of the hinge shaft; and through holes are fixedly installed at both ends of the swing plate. The through holes at both ends of the swing plate facilitate the connection of ropes, allowing the hinge shaft to rotate and thus precisely control the valve plate to switch between the first and second positions. This improves the control accuracy of the dispensing valve on the grain flow direction, further enhancing the accuracy and stability of dispensing, ensuring the stable operation of the grain dryer, and facilitating efficient drying operations.

[0015] As can be seen from the above technical solution, the advantages of this utility model include: the bottom surface of the valve plate is hinged to the shell, and the hinge is located on the center line of the input end and the middle of the shell. With the funnel fixedly set inside the input end, the grain can be guided to the valve plate more concentratedly and evenly during input, which can effectively improve the accuracy and stability of material distribution, reduce the grain from falling into the first output end and the second output end at the same time during the process of the valve plate turning from the first position to the second position, which is beneficial to the application of scenarios that require precise material distribution and increases applicability.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1 and Figure 2 As shown, a dispensing valve for a grain dryer includes a housing 1. The housing 1 includes an input end 101, a first output end 102, and a second output end 103. A valve plate 2 is rotatably disposed inside the housing 1. The valve plate 2 can move from a first position that cuts off the first output end 102 to a second position that cuts off the second output end 103. The valve plate 2 is connected to a driving mechanism. The bottom surface of the valve plate 2 is hinged to the housing 1 at the center. The hinge point between the valve plate 2 and the housing 1 is located on the center line of the input end 101 and is located in the middle of the housing 1. A funnel 3 is fixedly disposed inside the input end 101 in conjunction with the valve plate 2.

[0025] The valve plate 2 is hinged to the housing 1 at the center of its bottom surface, with the hinge point located on the center line of the input end 101 and in the middle of the housing 1. Together with the funnel 3 fixed inside the input end 101, this design allows the grain to be guided more concentratedly and evenly onto the valve plate 2 during input. During use, the grain falls from the input end through the funnel 3 onto the valve plate 2. The drive mechanism rotates the valve plate 2 between a first position and a second position. When the valve plate is in the first position, the first output end is closed, and the grain flows to the second output end. When it is in the second position, the second output end is closed, and the grain flows to the first output end. This design effectively improves the accuracy and stability of the material distribution, reduces the possibility of grain falling into both output ends simultaneously during valve plate position changes, and increases its applicability in scenarios requiring high material distribution accuracy.

[0026] like Figure 4 As shown, the valve plate 2 includes a base plate 201; side plates 202 are fixedly installed on both sides of the base plate 201 along its length; the space enclosed by the base plate 201 and the two side plates faces the input end 101; a hinge shaft 203 is installed in the middle of the bottom surface of the base plate 201; the hinge shaft 203 is hinged to the housing 1. A mounting frame 204 with a U-shaped cross-section is fixedly installed in the middle of the bottom surface of the base plate 201; the hinge shaft 203 is detachably installed in the mounting frame 204. A through hole 205 is provided on the mounting frame 204; the through hole 205 penetrates the base plate 201; a radial hole is provided on the hinge shaft 203 to cooperate with the through hole 205.

[0027] The valve plate 2, rationally configured with a base plate 201 and two side plates 202, effectively receives and guides the grain flow. A hinge shaft 203 is mounted at the center of the bottom surface of the base plate 201, hinged to the housing 1. Working in conjunction with the rotating valve plate 2 and drive mechanism within the housing 1, the grain flow direction can be precisely controlled. Simultaneously, the U-shaped mounting frame 204 at the center of the bottom surface provides a stable and compatible mounting base for the hinge shaft 203, which can be detachably installed within it, greatly improving the ease of maintenance of the feed valve for the grain dryer and reducing maintenance costs. The through hole 205 of the mounting frame 204 mates with the radial hole of the hinge shaft 203, facilitating precise assembly and ensuring the strong connection between the hinge shaft 203 and the mounting frame 204. During use, grain enters from the input end 101 and falls into the space of the valve plate 2 enclosed by the bottom plate 201 and the side plate 202. The drive mechanism drives the hinge shaft 203 to rotate, thereby controlling the rotation of the valve plate 2 to switch positions and realize the distribution of grain to different output ends. During installation, the hinge shaft 203 is fixed in the mounting frame 204 by bolts passing through the through hole 205 and the radial hole. When the hinge shaft 203 needs maintenance or replacement, it can be easily disassembled for operation. The reasonable setting of the valve plate 2 can effectively receive and guide the grain flow. The hinge shaft 203, which is installed in the middle of the bottom surface of the bottom plate 201, is hinged to the housing 1. Together with the valve plate 2 and the drive mechanism that are rotated inside the housing 1, the flow direction of grain can be precisely controlled to stop different output ends. Meanwhile, the bottom center of the valve plate 2 is hinged to the housing 1 and located on the center line of the input end 101 and in the middle of the housing 1. It works in conjunction with the funnel 3 fixedly installed inside the input end 101 to guide the grain into the valve plate 2 more concentratedly and evenly, greatly improving the accuracy and stability of the material distribution, and further reducing the amount of grain falling into the first output end 102 and the second output end 103 at the same time.

[0028] like Figure 3As shown, the funnel 3 is configured as a frustum-shaped shell; the perpendicular distance from the center line of the hinge shaft 203 to the bottom surface of the funnel 3 is less than half the width of the base plate 201. A limiting plate 4 is fixedly installed inside the shell 1; the limiting plate 4 is set in the first and second positions in conjunction with the valve plate 2. The frustum-shaped shell of the funnel 3 facilitates the smooth and concentrated flow of grain towards the valve plate 2, and its unique shape effectively prevents grain from accumulating or spilling at the input end, optimizing the grain conveying path. The design that the perpendicular distance from the center line of the hinge shaft 203 to the bottom surface of the funnel 3 is less than half the width of the base plate 201 allows the grain to be more efficiently distributed to different output ends during the rotation of the valve plate 2. Because the reasonable distance setting ensures that the valve plate 2 controls the grain flow direction more precisely, it further reduces the amount of grain falling into the first output end 102 and the second output end 103 at the same time, thereby ensuring that the grain dryer can operate efficiently and stably under various working conditions. The limiting plate 4 fixedly installed inside the housing 1 cooperates with the first and second positions of the valve plate 2, which can effectively limit the rotation range of the valve plate 2, avoid excessive rotation and positional deviation, further ensure the accuracy of the valve plate 2 position during the material distribution process, and increase the applicability of the material distribution valve for the grain dryer.

[0029] In the above configuration, the end of the hinge shaft 203, after penetrating the housing 1, is provided with a truncated pyramid to facilitate the connection of an external drive device, such as a motor or rotary cylinder, for remote control of the valve plate 2's rotation, thereby controlling the grain flow direction. A swing plate 5 is fixedly mounted on the hinge shaft 203 near its edge; the middle of the swing plate 5 is located on the hinge shaft 203; and through holes 501 are fixedly mounted at both ends of the swing plate 5. The through holes 501 at both ends of the swing plate 5 facilitate the connection of ropes, allowing the hinge shaft 203 to rotate, thereby precisely controlling the valve plate 2 to switch between the first and second positions, improving the control accuracy of the grain flow direction, further enhancing the accuracy and stability of material distribution, ensuring the stable operation of the grain dryer, and facilitating efficient drying operations. In use, the lower end of the rope is placed at the bottom of the grain dryer, allowing for manual control of the material distribution valve installed at a higher position.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
