TECHNICAL FIELD
[0001] The present application belongs to the field of agricultural grain and granular fertilizer conveying equipment, in particular to an agricultural tunnel type blocking claw conveying device. BACKGROUND
[0002] The existing agricultural grain and granular fertilizer conveying equipment mainly has two types of screw stirring auger type conveyor and rubber belt type conveyor. The structure of the screw stirring auger type conveyor is relatively simple, but when conveying the grain and granular fertilizer, the screw stirring auger rotates at a relatively large speed to realize the conveying function, which will impact and crush the grain and granular fertilizer during the conveying process, causing grain loss and fertilizer application efficiency, and the production efficiency is low when conveying the grain and granular fertilizer at an inclination; the rubber belt type conveyor is a device commonly used by grain processing and storage users, which is generally designed as a multi-layer rubber belt, and support rollers are arranged on both sides of the rubber belt in the transverse direction to incline the rubber belt, so that the grain falls on the concave belt surface, and the continuous conveying of the grain is completed with the movement of the rubber belt. This kind of rubber belt type conveyor generally has a large size and a complex structure, and since no baffle is arranged on the rubber belt, backflow occurs during the inclined conveying of the material, so the production efficiency is significantly reduced when conveying at a large inclination angle. SUMMARY
[0003] The purpose of the present application is to provide an agricultural tunnel type blocking claw conveying device with simple structure, less crushing and high production efficiency in view of the above-mentioned problems.
[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: the agricultural tunnel type blocking claw conveying device of the present application comprises a shell, a feeding hopper, a discharging hopper and a mounting seat arranged on the shell, and further comprises a tunnel, a motor, a conveying belt, a driving roller and a driven roller. The shell is in the shape of a thin-walled long groove, the upper part of the cross section is in the shape of a dovetail groove, and the lower part is in the shape of a U-shaped groove. The tunnel is in the shape of a cylinder and is arranged on the upper part of the dovetail groove of the shell in the length direction, and the center plane of the tunnel is parallel to the bottom surface of the U-shaped groove of the shell. A feeding box is arranged at one end of the shell, and the feeding hopper is arranged on the feeding box. The driven roller is arranged on the feeding box to roll in the transverse direction. A discharging hopper is arranged at the other end of the shell, and the driving roller is arranged on the discharging hopper to roll in the transverse direction. The motor is arranged at the driving end of the driving roller. The width of the conveying belt is greater than the inner diameter of the cylinder of the tunnel, so that the working section of the conveying belt generates a transverse concave arc when passing through the tunnel in the length direction. The conveying belt is hung on the driving roller and the driven roller at both ends, respectively.
[0005] As a preferred embodiment of the present invention, a stop claw is provided on the center line of the conveyor belt surface. Along the transverse direction of the conveyor belt, two stop claws are symmetrically provided on each side of the stop claw. Adjacent two stop claws overlap along the transverse edge. Along the conveying direction of the conveyor belt surface, adjacent two stop claws are equally spaced, and the spacing is 2mm to 5mm. The five stop claws constitute a stop claw group. The stop claw group is equally spaced along the longitudinal direction of the conveyor belt.
[0006] As a preferred embodiment of the present invention, the feeding hopper is composed of a hopper ring and a soft skirt. The hopper ring is made of steel pipe and the body of the hopper ring is designed as a U-shape. The open end of the hopper ring is formed by symmetrically bending inward at the front end of the U-shaped body. A cloth sleeve is provided on the upper edge of the soft skirt, and the soft skirt is fitted onto the hopper ring through the cloth sleeve. The lower edge of the soft skirt is connected to the opening on the feeding box. The open end of the hopper ring is set on the swing mechanism.
[0007] As a preferred embodiment of the present invention, the tunnel is provided with an opening, and an inspection cover is provided on the opening. A primary baffle brush and a secondary baffle brush are fixedly installed in the feed box along the transverse direction. The primary baffle brush and the secondary baffle brush are arranged sequentially behind the opening on the feed box, and the lower ends of the primary baffle brush and the secondary baffle brush are pressed against the surface of the conveyor belt.
[0008] As a preferred embodiment of the present invention, the swing mechanism includes a handle, an ear seat, a connecting rod, and a swing seat. The ear seats are symmetrically arranged on both sides of the tunnel. One end of the swing seat is hinged to the upper end of the ear seat. The open end of the hopper ring is fixed to the swing seat. The lower end of the handle is hinged to the lower part of the ear seat. The upper end of the connecting rod is hinged to the swing seat, and the lower end of the connecting rod is hinged to the handle.
[0009] By adopting the above technical solution, the agricultural tunnel-type claw conveyor provided by the present invention has the following advantages compared with the prior art: The five stoppers of this invention constitute a stopper group, which is equally spaced along the longitudinal direction of the conveyor belt. The width of the conveyor belt is greater than the inner diameter of the tunnel cylinder, causing a transverse concave arc to be generated when the working section of the conveyor belt passes through the tunnel along its length. Since adjacent stoppers are equally spaced (2mm-5mm) along the conveying direction of the conveyor belt surface, the five stoppers converge inward along the concave arc of the conveyor belt surface, forming a stopper group with both material blocking and conveying functions. The conveyor belt with this equally spaced stopper group is used to fill the transverse concave arc of the conveyor belt within the tunnel cylinder with grain or fertilizer granules. During conveying, the stopper group intercepts the material flow back. This avoids the high-speed rotational impact and crushing of spiral auger conveyors and overcomes the problems of large size, complex structure, and backflow caused by inclined material conveying in rubber belt conveyors. Therefore, it achieves the effects of simple structure, less breakage, and high production efficiency. Attached Figure Description

The tunnel 2 is cylindrical and is disposed along its length on the dovetail groove at the top of the housing 1, with the center plane of the tunnel 2 parallel to the bottom surface of the U-shaped groove at the bottom of the housing 1. A feeding box is disposed at one end of the housing 1, with a feeding hopper 3 opening on the top of the feeding box. A driven roller 13 is disposed on the feeding box and rolls laterally. A discharge hopper 4 is disposed at the other end of the housing 1, with a drive roller 12 rolling laterally on the discharge hopper 4. A motor 7 is disposed at the drive end of the drive roller 12. Figure 6 In this process, the width of the conveyor belt 8 is greater than the inner diameter of the cylinder of the tunnel 2, so that when the working section of the conveyor belt 8 passes through the tunnel 2 along the length direction, a transverse concave arc is generated. The two ends of the conveyor belt 8 are respectively attached to the driving roller 12 and the driven roller 13.
[0013] As a preferred embodiment of the present invention, such as Figure 4 , Figure 6 , Figure 8 As shown, a stopper 9 is provided on the center line of the conveyor belt 8. Along the transverse direction of the conveyor belt 8, two stoppers 9 are symmetrically provided on each side of the stopper 9. Adjacent stoppers 9 overlap along the transverse edge. Along the conveying direction of the conveyor belt 8, adjacent stoppers 9 are equally spaced, with a spacing of 2mm to 5mm. The five stoppers 9 constitute a stopper group, which is equally spaced along the longitudinal direction of the conveyor belt 8.
[0014] As a preferred embodiment of the present invention, such as 1, Figure 2 , Figure 3 , Figure 6 , Figure 10 , Figure 11 As shown, the feeding hopper 3 consists of a hopper ring 11 and a soft skirt. The hopper ring 11 is made of steel pipe and the body of the hopper ring 11 is designed as a U-shape. The open end of the hopper ring 11 is formed by symmetrically bending inward at the front end of the U-shaped body. A cloth cover is provided on the upper edge of the soft skirt, and the soft skirt is fitted onto the hopper ring 11 through the cloth cover. The lower edge of the soft skirt is connected to the opening on the feeding box. The open end of the hopper ring 11 is set on the swing mechanism.
[0015] As a preferred embodiment of the present invention, such as 1, Figure 4 , Figure 6As shown, the tunnel 2 has an opening, and an inspection cover 6 is installed on the opening. A primary baffle brush 14 and a secondary baffle brush 15 are fixedly installed horizontally inside the feeding box. The primary baffle brush 14 and the secondary baffle brush 15 are arranged sequentially behind the opening on the feeding box. The lower ends of the primary baffle brush 14 and the secondary baffle brush 15 are pressed against the surface of the conveyor belt 8.
[0016] As a preferred embodiment of the present invention, such as 10, Figure 11 As shown, the swing mechanism includes a handle 10, an ear seat 16, a connecting rod 17, and a swing seat 18. The ear seats 16 are symmetrically arranged on both sides of the tunnel 2. One end of the swing seat 18 is hinged to the upper end of the ear seat 16. The open end of the hopper ring 11 is fixed to the swing seat 18. The lower end of the handle 10 is hinged to the lower part of the ear seat 16. The upper end of the connecting rod 17 is hinged to the swing seat 18, and the lower end of the connecting rod 17 is hinged to the handle 10.
[0017] The working principle of this invention is that during the conveying operation, the handle 10 of the swing mechanism controls the hopper ring 11 to lift upwards, such as... Figure 1 , Figure 4 , Figure 10 As shown, the soft skirt of the feeding hopper 3 is raised to receive material. At this time, grain or granular fertilizer is filled in. As the conveyor belt 8 moves, the material is kept in the transverse concave arc of the conveyor belt 8 and stays between the five guards 9. It can adapt to a large tilt angle of conveying, effectively avoid material backflow during the conveying process and reduce efficiency. It can convey at high speed without impacting or breaking the material. Moreover, the structure is compact and simple, and the ideal material conveying effect is achieved.
[0018] During shutdown operations, the hopper ring 11 can be lowered onto the feeding box by using the handle 10 of the swing mechanism. Figure 9 , Figure 11 As shown, the soft skirt of the feed hopper 3 is in a retracted state, which improves the adaptability of the conveying device.
[0019] This invention is applicable to the conveying of grains or granular fertilizers.
