Description

Technical Field

[0001] This utility model relates to the field of grain drying tower technology, specifically to a grain discharge device for a grain drying tower. Background Technology

[0002] Grain drying towers are important agricultural equipment used to reduce the moisture content of grains. The selection and configuration of grain drying towers are based on the relative movement direction of the grain and the airflow. Dryers can be classified into cross-flow, mixed-flow, co-flow, counter-flow, and co-counter-flow, mixed-counter-flow, and co-mixed-flow types. After the grain is dried in the drying tower, it is quickly discharged through a discharge device for convenient storage or use.

[0003] Although existing grain drying towers typically incorporate a grain distribution structure within the discharge hopper to prevent grain accumulation and blockage during the discharge process, facilitating even discharge, these devices cannot control the discharge volume according to demand. This hinders even grain discharge and can lead to blockages, impeding rapid discharge and reducing the overall efficiency of the grain drying tower. Utility Model Content

[0004] The purpose of this invention is to provide a grain discharge device for a grain drying tower to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grain discharge device for a grain drying tower, comprising a grain discharge hopper, wherein a grain discharge pipe is connected to the bottom of the grain discharge hopper, and the grain discharge hopper is provided with a grain distribution structure for dispersing the grain. The grain distribution structure includes a partition plate installed inside the grain discharge hopper, and a discharge port is provided in the middle of the partition plate; The grain discharge hopper is also equipped with a discharge control structure for opening and closing the discharge port. The discharge control structure includes mounting frames symmetrically fixed on both sides of the grain discharge hopper. An electric push rod is installed on one side of each of the two mounting frames. The telescopic ends of the two electric push rods extend into the mounting frames and are connected to connecting plates. A connecting rod is connected to one side of each of the two connecting plates. A movable plate is installed at the opposite end of each of the two connecting rods. A gate is installed on one side of each of the two movable plates. The two gates can extend into the discharge port. Cavities for the movable plates to move are opened on both sides of the interior of the partition plate.

[0006] Preferably, the material feeding control structure further includes a prompting component, which includes a mounting block installed on one side of the movable plate and a moving groove opened on one side of the mounting frame. One end of the mounting block passes through the moving groove and is equipped with an indicator block. The side wall of the mounting frame is also provided with equally spaced prompting blocks a, b, and c. The bottom of the indicator block forms a conical end pointing to prompting block a, b, or c.

[0007] Preferably, a sealing ring is embedded in the outer wall of the movable plate. The sealing ring is used to seal the movable plate and the inner wall of the cavity, which can prevent external air from overflowing into the grain discharge hopper through the cavity.

[0008] Preferably, the grain distribution structure further includes a shaft rotatably disposed inside the grain discharge hopper, on which multiple grain distribution plates are mounted, and a motor for driving the shaft to rotate is fixed on one side of the grain discharge hopper.

[0009] Preferably, one of the gates has two positioning blocks symmetrically installed at one end, and the other gate has a positioning groove at one end for the positioning blocks to be inserted, which can position the two gates and facilitate stable docking of the two gates.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] like Figures 1-6 As shown, a grain discharge device for a grain drying tower includes a grain discharge hopper 1, a grain discharge pipe 2 connected to the bottom of the grain discharge hopper 1, and a grain distribution structure 4 for dispersing grain inside the grain discharge hopper 1; an installation plate 5 is also installed on the top of the grain discharge hopper 1, and multiple evenly distributed installation holes are opened on the installation plate 5. The grain distribution structure 4 includes a partition plate 44 installed in the grain discharge hopper 1, with a discharge port in the middle of the partition plate 44; the grain distribution structure 4 also includes a shaft 43 rotatably installed in the grain discharge hopper 1, with multiple grain distribution plates 42 installed on the shaft 43, and a motor 41 for driving the shaft 43 to rotate is fixed on one side of the grain discharge hopper 1. The grain discharge hopper 1 is also equipped with a discharge control structure 3 for opening and closing the discharge port. The discharge control structure 3 includes mounting frames 31 symmetrically fixed on both sides of the grain discharge hopper 1. Electric push rods 32 are installed on one side of each of the two mounting frames 31. The telescopic ends of the two electric push rods 32 extend into the mounting frames 31 and are connected to connecting plates 36. Connecting rods 35 are connected to one side of each of the two connecting plates 36. Movable plates 34 are installed at the opposite ends of the two connecting rods 35. Gates 33 are installed on one side of each of the two movable plates 34. The two gates 33 can extend into the discharge port. Cavities for the movable plates 34 to move are opened on both sides of the interior of the partition plate 44.

[0017] In use, the grain discharge hopper 1 is first installed at the discharge end of the grain drying tower through the mounting plate 5 and mounting holes. When the grain drying tower discharges grain, the grain will fall into the grain discharge hopper 1. At this time, the motor 41 drives the shaft 43 to rotate, which causes the shaft 43 to drive multiple grain separating plates 42 to rotate, so as to stir and disperse the grain. Then, the grain falls through the discharge port on the partition plate 44 until it is discharged through the grain discharge pipe 2, thus completing the grain discharge of the grain drying tower. When the grain drying tower discharges grain through the discharge hopper 1, the connecting plate 36 can be moved along the mounting frame 31 by the electric push rod 32. Then, the connecting plate 36 drives the movable plate 34 to move along the cavity through the connecting rod 35. At this time, the movable plate 34 drives the gate 33 to move from the discharge port into the cavity to open the discharge port, so that the grain can be discharged through the discharge port, realizing the discharge of the grain drying tower. The moving distance of the gate 33 can be controlled by the electric push rod 32, that is, the distance between the two gates 33 can be adjusted to adjust the opening degree of the discharge port, thereby realizing the control of the discharge amount. This facilitates the uniform discharge of grain by the discharge device, avoids blockage during the discharge of grain, and is conducive to the rapid discharge of grain from the grain drying tower.

[0018] Meanwhile, in this embodiment, to facilitate accurate control of the opening degree of the feed port, such as Figure 1 , Figure 5 and Figure 6 As shown, the material feeding control structure 3 also includes a prompting component. The prompting component includes a mounting block installed on one side of the movable plate 34 and a moving groove 38 opened on one side of the mounting frame 31. One end of the mounting block passes through the moving groove 38 and is equipped with an indicator block 39. The side wall of the mounting frame 31 is also provided with equally spaced prompting blocks a310, b311 and c312. The bottom of the indicator block 39 forms a conical end pointing to the prompting block a310, b311 or c312.

[0019] In the process of controlling the feeding amount of the grain drying tower through the feeding control structure 3, when the electric push rod 32 drives the gate 33 to move through the connecting rod 35, connecting plate 36 and movable plate 34, the movable plate 34 will move along the cavity and drive the indicator block 39 to move synchronously along the moving groove 38 through the mounting block. When the conical end of the indicator block 39 points to the prompt block b311, it means that the feeding port is half open. When the conical end of the indicator block 39 points to the prompt block c312, it means that the feeding port is fully open. This adjusts the opening degree of the feeding port, thereby realizing the regulation and control of the grain feeding amount, which is conducive to the uniform discharge of grain from the grain drying tower. When the grain drying tower does not need to discharge grain, the gate 33 is driven into the feeding port by the electric push rod 32. The feeding port is closed by the docking of the two gates 33. At this time, the conical end of the indicator block 39 points to the prompt block a310, so that the opening and closing status of the feeding port can be monitored in real time, which facilitates the precise control of the grain discharge amount of the grain drying tower.

[0020] Furthermore, to ensure a seal between the movable plate 34 and the inner wall of the cavity, and to prevent external air from leaking into the grain discharge hopper 1 through the cavity, such as... Figures 3-5 As shown, a sealing ring is embedded in the outer wall of the movable plate 34, which is used to seal the movable plate 34 with the inner wall of the cavity.

[0021] Furthermore, such as Figure 5 As shown, one of the gate plates 33 has two positioning blocks 37 symmetrically installed on one end, and the other gate plate 33 has a positioning groove for the positioning blocks 37 to be inserted into one end.

[0022] When the two gates 33 are connected and the discharge port is closed, the positioning block 37 at the end of one gate 33 will be inserted into the positioning groove at the end of the other gate 33 to position the two gates 33, thereby facilitating the stable connection of the two gates 33 and achieving stable sealing of the discharge port.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
