Description

Technical Field

[0001] This utility model relates to the field of grain conveyor technology, specifically to an anti-breakage spiral propulsion device for grain conveyors. Background Technology

[0002] A grain conveyor is a machine used in grain processing to transport grain particles. Conveyors can be made in various ways, such as conveyor belt conveying or spiral push.

[0003] The existing anti-breakage screw propulsion device for grain conveyors directly feeds grain into the feeding cylinder through the inlet. Under the rotation of the screw, the grain is propelled. However, when the grain is fed in, a large amount of debris and impurities are mixed in with it. The impurities are pushed into the feeding cylinder along with the grain. The impurities are crushed by the grain and may be blocked by the large accumulation. In addition, the grain pushed along with the impurities will also increase the burden of subsequent impurity removal.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a grain conveyor anti-breakage spiral propulsion device. Utility Model Content

[0005] The purpose of this invention is to provide an anti-breakage spiral propulsion device for a grain conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crush-resistant spiral propulsion device for a grain conveyor, comprising a feeding cylinder, a feed box fixedly connected to the left side of the upper surface of the feeding cylinder, an expansion chamber fixedly connected to the left side of the surface of the feed box, an exhaust box fixedly connected to the right side of the surface of the feed box, a shaft rotatably connected to the left side of the inner surface of the expansion chamber, a fan fixedly connected to the right end of the shaft inside the expansion chamber, a first pulley fixedly connected to the left end of the shaft, a double-ended motor fixedly connected to the left side of the outer surface of the feeding cylinder, a second pulley installed at the left end of the double-ended motor, and the first pulley and the second pulley connected by a transmission belt.

[0007] Preferably, the exhaust box is configured as a horizontally placed "Y"-shaped funnel, and the horizontal central axis of the exhaust box is on the same horizontal line as the fan.

[0008] Preferably, air grooves are evenly distributed on the left side of the outer surface of the expansion chamber around the shaft penetration part, and a barrier net is fixedly connected to the right side of the inner surface of the expansion chamber.

[0009] Preferably, the feed cylinder is provided with a spiral rod inside, and the spiral rod is composed of a rod body and a spiral plate on the surface of the rod body.

[0010] Preferably, the left end of the screw rod is connected to the right output shaft of the double-ended motor, and the spiral plate of the screw rod slides in contact with the inner surface of the feeding cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the arrangement of an exhaust box, shaft, fan, first pulley, double-ended motor, and second pulley, allows the double-ended motor to be started before feeding into the feed box. The left output shaft of the double-ended motor drives the second pulley to rotate, which in turn causes the first pulley to rotate under the traction of the transmission belt, thereby driving the fan to rotate. The fan blows air into the feed box, and the air is discharged through the exhaust box. When grain is fed into the feed box, the weight of the full grain particles is large, while the weight of impurities and debris is extremely light. Therefore, the grain particles are not affected by the fan blowing, while the impurities and debris mixed in the grain can be discharged through the exhaust box with the airflow. The large opening at the left end of the exhaust box can capture more diffused airflow, thereby fully guiding the airflow to carry away the impurities and debris. This allows for the effective removal of debris and impurities mixed in the grain particles before feeding and pushing the grain. This not only avoids small and scattered impurities and debris from being squeezed and broken by the grain particles during pushing, which could cause blockage of the pushing device, but also reduces the workload of subsequent grain impurity removal.

[0013] 2. This utility model, through the configuration of a double-ended motor and a screw rod, allows the double-ended motor to drive the fan while simultaneously rotating the right-end output shaft, which in turn drives the screw rod to rotate. The screw rod, utilizing the rotation of the spiral plate, pushes the grain particles in the feeding cylinder from left to right. Furthermore, the spiral plate slides smoothly against the inner surface of the feeding cylinder, preventing grain particles from being squeezed into the gap between the spiral plate and the feeding cylinder, thus avoiding crushing of the grain due to the rotating spiral plate. This ensures the quality of grain conveying. The entire device, driven by a single energy source (the double-ended motor), can perform both impurity removal and conveying functions, greatly improving the practicality of the propulsion device and reducing energy waste.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown, a grain conveyor anti-breakage spiral propulsion device includes a feeding cylinder 1. A feed box 2 is fixedly connected to the left side of the upper surface of the feeding cylinder 1. An expansion chamber 3 is fixedly connected to the left side of the surface of the feed box 2. An exhaust box 4 is fixedly connected to the right side of the surface of the feed box 2. A shaft 5 is rotatably connected to the left side of the inner surface of the expansion chamber 3. A fan 6 is fixedly connected to the right end of the shaft 5 inside the expansion chamber 3. A first pulley 7 is fixedly connected to the left end of the shaft 5. A double-ended motor 8 is fixedly connected to the left side of the outer surface of the feeding cylinder 1. A second pulley 9 is installed at the left end of the double-ended motor 8. The first pulley 7 and the second pulley 9 are connected by a transmission belt.

[0020] By adopting the above technical solution, the grain that needs to be pushed can be put into the feeding cylinder 1 using the feeding box 2;

[0021] Before feeding material into the feed box 2, start the double-ended motor 8. The output shaft of the left end of the double-ended motor 8 will drive the second pulley 9 to rotate. Under the traction of the transmission belt, the first pulley 7 will rotate, thereby driving the fan 6 to rotate. The fan 6 blows air into the feed box 2. The air will be discharged through the exhaust box 4. When grain is put into the feed box 2, because the weight of the full grain particles is large, while the weight of the impurities and debris is extremely light, the grain particles will not be affected by the blowing of the fan 6. The impurities and debris mixed in the grain can be discharged through the exhaust box 4 with the airflow.

[0022] A cloth bag can be manually installed at the outlet of the exhaust box 4, and other collection bags can be used to collect debris.

[0023] Furthermore, the exhaust box 4 is configured as a horizontally placed "Y"-shaped funnel, and the horizontal central axis of the exhaust box 4 is on the same horizontal line as the fan 6.

[0024] By adopting the above technical solution, the left end of the exhaust box 4 has a large opening, which can capture more diffused airflow, thereby fully guiding the airflow to carry away impurities and debris.

[0025] Furthermore, air grooves 10 are evenly distributed around the shaft 5 through part on the left side of the outer surface of the expansion chamber 3, and a barrier net 11 is fixedly connected to the right side of the inner surface of the expansion chamber 3.

[0026] By adopting the above technical solution, when the fan 6 rotates, it can draw in fresh air from the outside through the air groove 10 and blow it into the feed box 2;

[0027] The barrier net 11 can prevent dust and impurities from entering the feed box 2 with the fresh air, thus preventing dust from contaminating the grain.

[0028] Furthermore, the inside of the feeding cylinder 1 is provided with a screw rod 12, and the screw rod 12 is composed of a rod body and a spiral plate on the surface of the rod body;

[0029] The left end of the screw rod 12 is connected to the right output shaft of the double-end motor 8, and the screw plate of the screw rod 12 slides and fits against the inner surface of the feeding cylinder 1.

[0030] By adopting the above technical solution, while the dual-end motor 8 drives the fan 6 to rotate, the right-end output shaft will also drive the screw rod 12 to rotate. The screw rod 12 can push the grain particles in the feeding cylinder 1 from left to right by utilizing the rotation of the screw plate.

[0031] The spiral plate slides in close contact with the inner surface of the feeding cylinder 1, which can prevent grain particles from being squeezed into the gap between the spiral plate and the feeding cylinder 1, thus avoiding the situation where the grain is crushed due to the rotation and crushing of the spiral plate.

[0032] Working Principle: When using the anti-breakage screw propulsion device of this grain conveyor, firstly, before feeding material into the feed box 2, the double-end motor 8 is started. The left output shaft of the double-end motor 8 drives the second pulley 9 to rotate, which in turn causes the first pulley 7 to rotate under the traction of the transmission belt, thereby driving the fan 6 to rotate. The fan 6 blows air into the feed box 2, and the air is discharged through the exhaust box 4. When grain is fed into the feed box 2, because the weight of full grain particles is large, while the weight of impurities and debris is extremely light, the grain particles are not affected by the blowing of the fan 6. The impurities and debris mixed in the grain can be discharged through the exhaust box 4 with the airflow. The large opening at the left end of the exhaust box 4 allows it to capture more diffused airflow, thus effectively guiding the airflow to carry away impurities and debris. Simultaneously, the dual-end motor 8 drives the fan 6, while its right-end output shaft also drives the screw rod 12. The screw rod 12, utilizing the rotation of the spiral plate, pushes the grain particles in the feeding cylinder 1 from left to right. Furthermore, the spiral plate slides smoothly against the inner surface of the feeding cylinder 1, preventing grain particles from being squeezed into the gap between the spiral plate and the feeding cylinder 1, thus avoiding the situation where the rotating spiral plate crushes the grain and ensures the quality of grain conveying. This is the working principle of the anti-breakage spiral propulsion device of this grain conveyor.
