Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an agricultural hoist and an agricultural conveying system. Background Technology

[0002] Bucket elevators are lifting devices characterized by forced continuous conveying, widely used in modern agricultural grain transportation, primarily for vertically conveying various bulk and granular materials. Their working principle involves the continuous power output of a drive unit, causing a belt to propel the buckets upwards at a constant speed along a pre-set track. When the buckets reach the top, the material is discharged through the outlet, completing one full conveying cycle.

[0003] In the existing technology, when a bucket elevator lifts materials, there is often severe friction between the materials and the inner wall of the elevator shell. This not only makes the shell prone to wear and damage, but also causes the materials to break due to severe wear and compression. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural elevator and an agricultural conveying system to solve the technical problem that severe wear easily occurs between the internal material and the shell of the bucket elevator in the prior art.

[0005] To achieve the above objectives, this utility model provides an agricultural hoist, comprising:

[0006] The shell includes a top plate, a bottom plate, and multiple side plates connecting the top plate and the bottom plate. The bottom plate has an inlet and an outlet.

[0007] The belt conveyor extends along the height direction, passes through the feed inlet, and is partially located inside the housing.

[0008] Multiple buckets are arranged circumferentially around the outer periphery of the belt conveyor. The belt conveyor drives the buckets to move to transport materials from the feed inlet to the discharge outlet. The height of the top plate is higher than the height of the highest point of the material's transport trajectory.

[0009] Multiple inner lining plates are respectively attached to the bottom wall of the top plate and the inner wall of the side plate near the discharge port.

[0010] In some implementations, multiple inner lining plates are made of wear-resistant materials.

[0011] In some embodiments, the agricultural elevator further includes a flow guiding assembly installed between two side plates arranged in the width direction and embedded in the belt conveyor, the flow guiding assembly being used to guide the material entering the belt conveyor to the feed inlet.

[0012] In some embodiments, the flow guiding assembly includes: a first flow guiding plate having an inclined first flow guiding surface, the top end of the first flow guiding plate being inclined toward the discharge port, and the bottom end of the first flow guiding plate extending to the inlet; and a second flow guiding plate mounted on the first flow guiding surface, the second flow guiding plate having two second flow guiding surfaces arranged at an included angle, each second flow guiding surface being arranged at an obtuse angle with the first flow guiding surface, and the side of the second flow guiding plate facing away from the first flow guiding surface being parallel to and spaced apart from the inner sidewall of the belt conveyor.

[0013] In some embodiments, the first guide plate also has two connecting edges, which are located on both sides of the first guide plate along the width direction, and the connecting edges are connected to two side plates arranged along the width direction.

[0014] In some embodiments, a discharge cylinder is provided around the discharge port, and a guide plate is installed on the side of the discharge cylinder near the belt conveyor. There is a gap between the vertical line where one end of the guide plate is located and the connecting line where the outer ends of the multiple buckets are located, and the gap ranges from 1mm to 10mm.

[0015] In some embodiments, the guide plate has a waist-shaped hole, and a locking member is also installed on the guide plate. The locking member is used to pass through the waist-shaped hole and lock the guide plate and the discharge cylinder.

[0016] In some embodiments, the top plate includes a first top plate portion and a second top plate portion, the second top plate portion being connected between the first top plate portion and a side plate near the discharge port, the second top plate portion forming an obtuse angle with both the first top plate portion and the side plate near the discharge port.

[0017] In some embodiments, the openings of the multiple buckets are all oriented towards the material conveying direction, and the multiple buckets are evenly spaced apart.

[0018] The second aspect of this utility model provides an agricultural conveying system, including the above-mentioned agricultural elevator.

[0019] The above-described technical solution provides an agricultural elevator, which includes a shell, a belt conveyor, multiple buckets, and multiple inner lining plates. The shell includes a top plate, a bottom plate, and multiple side plates connecting the top and bottom plates. The bottom plate has an inlet and an outlet. The belt conveyor extends along the height direction, passes through the inlet, and is partially located within the shell, driving the buckets. Multiple buckets are circumferentially spaced around the outer periphery of the belt conveyor, and the belt conveyor, through its movement, drives the buckets to transport material from the inlet to the outlet. The top plate is designed to be higher than the highest point of the material's transport trajectory to prevent severe and high-frequency friction between the material and the top wall during transport. To further enhance the shell's wear resistance and service life, multiple inner lining plates are respectively attached to the bottom wall of the top plate and the inner wall of the side plates near the outlet. These inner lining plates prevent direct friction between the material and the shell, reducing wear and tear and extending the service life of the agricultural elevator.

[0048] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0049] The agricultural hoist and agricultural conveying system according to the present invention are described below with reference to the accompanying drawings.

[0050] like Figure 1 The diagram shown is a structural schematic of an agricultural hoist provided according to an embodiment of the present invention; as shown... Figure 2 The diagram shown is a schematic representation of the movement trajectory of materials in an agricultural elevator according to an embodiment of the present invention; Figure 3 The image shown is a schematic diagram of the appearance of an agricultural hoist provided according to an embodiment of the present utility model; as shown Figure 4The diagram shown is a simulation illustration of materials in an agricultural elevator according to an embodiment of the present invention. The agricultural elevator provided in this embodiment of the present invention includes:

[0051] The housing 10 includes a top plate 11, a bottom plate, and a plurality of side plates 12 connected between the top plate 11 and the bottom plate. The bottom plate has an inlet 13 and an outlet 14.

[0052] The belt conveyor 20 extends along the height direction, and the belt conveyor 20 is installed through the feed inlet 13 and is partially located inside the housing 10;

[0053] Multiple buckets 30 are arranged circumferentially around the outer periphery of the belt conveyor 20. The belt conveyor 20 is used to drive the buckets 30 to move to transfer materials from the feed inlet 13 to the discharge outlet 14. The height of the top plate 11 is higher than the height of the highest point of the material's transmission trajectory.

[0054] Multiple inner lining plates 40 are respectively attached to the bottom wall of the top plate 11 and the inner wall of the side plate 12 near the discharge port 14.

[0055] Agricultural elevators can lift materials such as grain and fertilizer from a low position to a high position to achieve material transfer. For example, to transfer grain from a grain transfer vehicle at a low position to the grain silo inlet at a high position, the feed inlet 13 of the agricultural elevator is connected to the outlet of the grain transfer vehicle, and the discharge outlet 14 of the agricultural elevator is connected to the grain silo inlet. The belt conveyor 20 drives the bucket 30 to continuously transfer the grain.

[0056] Specifically, the agricultural elevator provided in this embodiment includes a housing 10, a belt conveyor 20, multiple buckets 30, and multiple inner lining plates 40. The housing 10 serves as the main structure of the agricultural elevator, supporting and protecting the internal components. The housing 10 includes a top plate 11, a bottom plate, and multiple side plates 12 connecting the top plate 11 and the bottom plate. The bottom plate has an inlet 13 and an outlet 14, used for material input and output from the housing 10, respectively. The belt conveyor 20 extends along the height direction, passing through the inlet 13 and partially located within the housing 10, driving the movement of the buckets 30. The lower half of the belt conveyor 20 extends outside the housing 10, communicating with the lower hopper. The buckets 30 are arranged circumferentially around the outer periphery of the belt conveyor 20. Through the movement of the belt conveyor 20, the buckets 30 can transport the material below to the inlet 13 and further to the outlet 14. The top plate 11 is designed to be higher than the highest point of the material conveying trajectory. This design prevents severe friction between the material and the top wall during conveying, thus avoiding material loss and wear on the housing 10. To further enhance the wear resistance and service life of the housing 10, multiple inner lining plates 40 are respectively attached to the bottom wall of the top plate 11 and the inner wall of the side plate 12 near the discharge port 14. Figure 2 As shown, when the bucket 30 is conveyed to the side of the belt conveyor 20 near the discharge port 14, the material inside the bucket 30 will be thrown into the discharge port 14, which is very easy to rub against the bottom wall of the top plate 11 and the inner wall of the side plate 12 near the discharge port 14. Therefore, setting the inner lining plate 40 on the bottom wall of the top plate 11 and the inner wall of the side plate 12 near the discharge port 14 can effectively avoid direct friction between the material and the shell 10, reduce the wear of the shell 10, and thus extend the service life of the agricultural elevator.

[0057] In one embodiment, the multiple inner liner plates 40 are all made of wear-resistant material. The inner liner plates 40 will rub against materials at high frequency and intensity; therefore, inner liner plates 40 made of wear-resistant material can better withstand this friction, reduce wear, and extend service life. In one specific embodiment, the inner liner plate 40 is made of polyurethane material.

[0058] In one specific embodiment, the inner liner 40 is detachably connected to the side plate 12 or the top plate 11. When the inner liner 40 is worn to a certain extent, a new inner liner 40 can be replaced in time without replacing the entire top plate 11 or side plate 12, thus reducing usage costs. The connection method between the inner liner 40 and the side plate 12 or top plate 11 can be bolt connection, snap-fit ​​connection, etc., which facilitates disassembly and assembly.

[0059] In one embodiment, an observation window (not shown in the figure) is also provided on the side plate 12, and a transparent plate 70 is provided on the observation window, which allows observation of the inside of the housing 10 through the transparent plate 70.

[0060] In one embodiment, the agricultural hoist further includes a rotary drive 60, which penetrates the side plate 12 of the housing 10 and drives the belt conveyor 20 to move.

[0061] In one embodiment, such as Figure 1 As shown, the agricultural elevator also includes a flow guiding component 50, installed between two side plates 12 arranged along the width direction and embedded in the belt conveyor 20. The flow guiding component 50 is used to guide the material entering the belt conveyor 20 to the feed inlet 13. During the process of conveying and scattering material by the bucket 30, some material may enter the belt conveyor 20 from the gap between the belt conveyor 20 and the side plates 12, affecting the normal operation of the belt conveyor 20. In this embodiment of the invention, the flow guiding component 50 is embedded in the belt conveyor 20, which can redirect the material flowing into the belt conveyor 20 back to the feed inlet 13. By using the above-mentioned flow guiding component 50, material accumulation inside the belt conveyor 20 can be avoided, thereby ensuring the normal operation of the belt conveyor 20, and also avoiding blockage and wear caused by material inside the belt conveyor 20.

[0062] In one embodiment, such as Figure 5The diagram shows the structure of the flow guiding assembly 50 according to an embodiment of the present invention. The flow guiding assembly 50 includes a first flow guiding plate 51 and a second flow guiding plate 52. The first flow guiding plate 51 has an inclined first flow guiding surface. The top end of the first flow guiding plate 51 is inclined towards the discharge port 14, and the bottom end of the first flow guiding plate 51 extends to the feed inlet 13. The second flow guiding plate 52 is installed on the first flow guiding surface and has two second flow guiding surfaces. The two second flow guiding surfaces are arranged at an angle, and each second flow guiding surface is arranged at an obtuse angle with the first flow guiding surface. The side of the second flow guiding plate 52 facing away from the first flow guiding surface is parallel to and spaced apart from the inner sidewall of the belt conveyor 20. The flow guiding assembly 50 is installed inside the belt conveyor 20. When the material is conveyed from above to the first flow guiding plate 51, it will continue to move downwards along the first flow guiding plate 51 until it is guided to the feed inlet 13. When the material is conveyed to the second guide plate 52, it moves along the second guide surface to the first guide surface and is further guided to the feed inlet 13. The second guide plate 52 has two second guide surfaces arranged at an angle. The presence of the second guide surfaces allows the material to move towards the first guide surfaces on both sides, preventing material from accumulating in the gap between the belt conveyor 20 and the first guide plate 51, thus affecting the normal operation of the belt conveyor 20. By using the above-mentioned guide assembly 50, the material entering the belt conveyor 20 can be effectively guided back to the feed inlet 13, avoiding the accumulation and blockage of material inside the belt conveyor 20 and ensuring the normal operation of the belt conveyor 20. In addition, the side of the second guide plate 52 facing away from the first guide surface is parallel to and spaced apart from the inner wall of the belt conveyor 20. This design can reduce the friction between the material and the inner wall of the belt conveyor 20, further reducing wear and improving the service life of the agricultural elevator.

[0063] In one embodiment, the first guide plate 51 also has two connecting edges 53, which are located on both sides of the first guide plate 51 along its width direction. The connecting edges 53 are connected to two side plates 12 arranged along the width direction. The connection edges 53 make it easier to connect the guide assembly 50 to the side plates 12. The connecting edges 53 can be welded to the side plates 12 or detachably connected by bolts and nuts, enabling the guide assembly 50 to stably guide the material. In addition, installing the belt conveyor 20 after installing the guide assembly 50 can help position the belt conveyor 20 during installation.

[0064] In one embodiment, a discharge cylinder is provided around the discharge port 14, and a guide plate 15 is installed on the side of the discharge cylinder near the belt conveyor 20. A gap exists between the vertical line containing one end of the guide plate 15 and the connecting line containing the outer ends of the multiple bucket components 30, with the gap ranging from 1mm to 10mm. The discharge cylinder is a component used to guide and collect the material discharged from the discharge port 14. The guide plate 15 is installed on the side of the discharge cylinder near the belt conveyor 20 to further guide the material to smoothly discharge from the discharge port 14 and fall into a predetermined collection device. The gap between the guide plate 15 and the outer ends of the bucket components 30 is cleverly designed, ensuring smooth passage of the bucket components 30 while avoiding material spillage due to excessive gap. The gap range of 1mm to 10mm is the optimal range obtained through multiple tests and optimizations, ensuring the stability and efficiency of the agricultural elevator during operation.

[0065] In one embodiment, such as Figure 6 The diagram shows the outer trajectory of the bucket of an agricultural elevator according to an embodiment of the present invention. A waist-shaped hole 16 is provided on the guide plate 15, and a locking member 17 is also installed on the guide plate 15. The locking member 17 passes through the waist-shaped hole 16 and locks the guide plate 15 and the discharge cylinder. The gap between the vertical line where one end of the guide plate 15 is located and the connecting line where the outer ends of the multiple bucket components 30 are located can be adaptively adjusted according to the type of material. Specifically, by locking the locking member 17 at different positions in the waist-shaped hole 16, the gap between the guide plate 15 and the connecting line where the outer ends of the bucket components 30 are located can be adjusted to accommodate bucket components 30 of different sizes and types and different types of materials, enhancing the versatility and flexibility of the agricultural elevator. In one specific embodiment, there are multiple waist-shaped holes 16 extending in the same direction.

[0066] In one embodiment, such as Figure 1As shown, the top plate 11 includes a first top plate portion 111 and a second top plate portion 112. The second top plate portion 112 is connected between the first top plate portion 111 and a side plate 12 near the discharge port 14. The second top plate portion 112 forms an obtuse angle with both the first top plate portion 111 and the side plate 12 near the discharge port 14. The top plate 11 provided by this utility model includes a first top plate portion 111 and a second top plate portion 112. The design of the second top plate portion 112 causes the top plate 11 to form a gradually downward inclined surface on the side near the discharge port 14. This design not only conforms to the movement trajectory of the material during the transmission process, reducing friction and collision between the material and the top plate 11, but also makes the overall structure of the agricultural elevator more compact and occupies less space. At the same time, the obtuse angle between the second top plate portion 112 and both the first top plate portion 111 and the side plate 12 near the discharge port 14 further enhances the strength and stability of the top plate 11, ensuring the safety and reliability of the agricultural elevator during long-term use.

[0067] In one embodiment, the openings of the multiple buckets 30 all face the material conveying direction, and the multiple buckets 30 are evenly spaced apart. The opening design of the buckets 30 allows the material to enter smoothly and be carried and conveyed, while the even spacing ensures the stability and uniformity of the material during the conveying process, avoiding the accumulation and jamming of material between the buckets 30.

[0068] In one embodiment, an agricultural conveying system is provided, including the agricultural elevator described above.
