Description

Technical Field

[0001] This utility model relates to the field of rice production technology, specifically to an adjustable scraper conveyor. Background Technology

[0002] The rice production process covers multiple stages, from rice planting and harvesting to rice processing and packaging. The transportation stage in the rice production process is very important, involving the receiving, cleaning, and processing of rice to the packaging and distribution of the final product. In order to ensure that the production process is efficient and smooth, a variety of transportation equipment is usually used.

[0003] The scraper conveyor is mainly used in rice production to handle bulk materials such as paddy rice, rice bran, and rice husks in the production line. It is a common chain conveyor with strong adaptability, capable of conveying various materials such as paddy rice, rice bran, and rice, and is suitable for granular, powdery, and bulk materials. In the process of developing this utility model, the inventor discovered the following problems with the existing technology:

[0004] 1. Materials such as rice, rice bran, and rice husks are all granular. When they are conveyed from the conveyor to the other end, they fall from the discharge port in a concentrated manner. The existing discharge port positions are fixed. The concentrated fall of materials causes gaps on both sides of the receiving box, which accumulates in the center. When the accumulation reaches a certain height, it is easy to block the discharge port, increasing the risk of blockage and affecting the continuity of production.

[0005] 2. Different types of materials require different sizes of receiving boxes during the conveying process. The size and position of the discharge port cannot be adjusted according to the size of the receiving box, and the coverage area of ​​the discharge port cannot be guaranteed. Materials may leak or fall onto the ground around the receiving box. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable scraper conveyor to solve the problems mentioned in the background art, such as the fixed position of the discharge port, which cannot be moved, and the inability to adjust the coverage area of ​​the discharge port according to the receiving box. To achieve the above objective, this utility model provides the following technical solution: an adjustable scraper conveyor, including a chute, with a feed port at the top of one end of the chute, a discharge assembly at the other end of the chute, and a conveying assembly installed inside the chute.

[0007] The discharge assembly includes a slide plate with a discharge port on its surface. Baffles are slidably connected to both sides of the discharge port. A connecting rod is rotatably connected to the back of the slide plate. A slider is rotatably connected to the other end of the connecting rod. A rotating rod is slidably connected to the surface of the slider. A lead screw is rotatably connected to the inner wall of the rotating rod. A rotating shaft is welded to one end of the rotating rod. The output shaft of a first motor is installed at one end of the rotating shaft.

[0008] More preferably, the conveying assembly includes a sprocket, a chain meshing on the surface of the sprocket, a guide plate connected to one side of the chain by bolts, and the output shaft of a second motor mounted on the inner wall of the sprocket.

[0009] More preferably, the bottom of the chute near the discharge assembly is designed as an open structure, and the slide plate is slidably connected to the bottom of the chute.

[0010] More preferably, the slide plate is configured to reciprocate linearly via a connecting rod.

[0011] More preferably, the rotating rod and the rotating shaft are arranged in a vertical structure, and the rotating rod forms a rotating structure through the first motor.

[0012] More preferably, the slider is configured into a sliding structure via a lead screw and a rotating rod.

[0013] More preferably, the first motor is externally mounted with a bracket, and a telescopic rod is mounted on the top of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, by setting an opening at the bottom of the chute, when the slide plate slides in a straight line along the opening, the solid part of the slide plate completely covers the opening. At this time, the position of the discharge port on the surface of the slide plate is the material discharge point. The change of the discharge port avoids material accumulation. The first motor drives the rotating shaft to rotate, which in turn drives the rotating rod to rotate around the rotating shaft, pulling the connecting rod to perform linear reciprocating motion. Through the pulling of the connecting rod, the slide plate is driven to perform linear reciprocating motion, which in turn drives the discharge port to perform linear reciprocating motion, resulting in uniform and stable material discharge.

[0016] In this invention, a rotating screw drives a slider to slide along a rotating rod. The rotating rod limits the position of the slider. By moving the slider, the position of the connection point between the connecting rod and the rotating rod is adjusted. When the rotating shaft rotates, the rotation center of the slider and the rotating rod changes, further adjusting the movement path of the connecting rod and the sliding plate, changing the coverage area of ​​the discharge port, and preventing the material from spilling onto the ground during the discharge process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an adjustable scraper conveyor, including a chute 1, a feed inlet 2 at the top of one end of the chute 1, a discharge component 3 at the other end of the chute 1, and a conveying component 4 installed inside the chute 1.

[0025] The discharge assembly 3 includes a slide plate 301, a discharge port 302 is provided on the surface of the slide plate 301, baffles 303 are slidably connected to both sides of the discharge port 302, a connecting rod 304 is rotatably connected to the back of the slide plate 301, a slider 305 is rotatably connected to the other end of the connecting rod 304, a rotating rod 306 is slidably connected to the surface of the slider 305, a lead screw 307 is rotatably connected to the inner wall of the rotating rod 306, a rotating shaft 308 is welded to one end of the rotating rod 306, and the output shaft of the first motor 309 is installed at one end of the rotating shaft 308.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the conveying assembly 4 includes a sprocket 401, with a chain 402 meshing on the surface of the sprocket 401. A guide plate 403 is bolted to one side of the chain 402, and the output shaft of a second motor 404 is installed on the inner wall of the sprocket 401. It should be noted that the second motor 404 drives the sprocket 401 to rotate, which in turn drives the chain 402 and the installed guide plate 403 to transmit power. The guide plate 403 pushes the material at the bottom of the chute 1 backward, and the feed port 2 is pushed to the position of the discharge assembly 3 at the other end, so as to realize continuous and stable conveying operation.

[0027] In this embodiment, as Figure 3 As shown, the bottom of the chute 1 near the discharge component 3 is designed with an open structure, and the slide plate 301 is connected to the bottom of the chute 1 by a sliding connection. It should be noted that the opening at the bottom of the chute 1 is relatively large. When the slide plate 301 slides in a straight line along the opening, the solid part of the slide plate 301 completely covers the opening. At this time, the position of the discharge port 302 on the surface of the slide plate 301 is the material discharge point. The change of the discharge port 302 avoids material accumulation.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, the slide plate 301 forms a linear reciprocating motion through the connecting rod 304; it should be noted that the connecting rod 304 pulls the slide plate 301 to perform linear reciprocating motion, which in turn drives the discharge port 302 to perform linear reciprocating motion, resulting in uniform and stable material feeding.

[0029] In this embodiment, as Figure 5 As shown, the rotating rod 306 and the rotating shaft 308 are arranged in a vertical structure, and the rotating rod 306 forms a rotating structure through the first motor 309. It should be noted that the first motor 309 drives the rotating shaft 308 to rotate, which in turn drives the rotating rod 306 to rotate around the rotating shaft 308. The rotating rod 306 and the rotating shaft 308 are perpendicular, and the rotating rod 306 is always located in the same plane and will not tilt. This avoids friction between the rotating rod 306 and the connecting rod 304, and improves the stability and durability of the system.

[0030] In this embodiment, as Figure 4 and Figure 5 As shown, the slider 305 forms a sliding structure with the lead screw 307 and the rotating rod 306. It should be noted that the slider 305 and the lead screw 307 are connected by a thread. One end of the lead screw 307 is equipped with a knob. When the lead screw 307 is rotated, the slider 305 is driven to slide along the rotating rod 306. The rotating rod 306 limits the position of the slider 305. By moving the slider 305, the position of the connection point between the connecting rod 304 and the rotating rod 306 is adjusted, further adjusting the movement path of the connecting rod 304 and the slide plate 301, changing the coverage area of ​​the discharge port 302, and preventing the material from spilling onto the ground during the discharge process.

[0031] In this embodiment, as Figure 4 As shown, the first motor 309 is externally mounted with a bracket, and a telescopic rod is mounted on the top of the bracket. It should be noted that there are two external brackets, and the telescopic rod is located between the two brackets. When the slider 305 moves, the telescopic rod extends and retracts to adjust the position of the first motor 309 and the rotating shaft 308, so as to ensure that the vertical center line position of the connection point of the connecting rod 304 of the slider 305 remains unchanged.

[0032] The usage and advantages of this utility model: The adjustable scraper conveyor operates as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, firstly, the second motor 404 is started, which drives the sprocket 401 to rotate, causing the chain 402 to perform a counterclockwise cyclical transmission motion. The guide plate 403 automatically pushes the material in the chute 1 towards the discharge component 3. Then, the first motor 309 is started, which drives the rotating shaft 308 to rotate. At this time, the rotating rod 306 starts to rotate around the connection point between the rotating shaft 308 and the rotating rod 306. The slider 305 starts to circle. As the position of the slider 305 changes, it pulls the connecting rod 304 to perform a back-and-forth reciprocating motion, further driving the slide plate. 301 and the discharge port 302 perform linear reciprocating motion. When the receiving box is small, the first motor 309 is turned off, and the baffles 303 on both sides of the discharge port 302 are slid open to cover both sides of the discharge port 302. Then the lead screw 307 reverses, driving the slider 305 to move to the right. The distance between the center point of rotation of the slider 305 and the right end of the rotating rod 306 decreases. The first motor 309 is restarted. At this time, the rotating rod 306 starts to rotate again, and the diameter of the circle drawn by the slider 305 becomes smaller. At this time, the movement path of the connecting rod 304 and the slide plate 301 is shortened, and vice versa.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
