Description

Technical Field

[0001] The utility model relates to the technical field of silos, in particular to a discharging and conveying device at the bottom of a silo. Background Art

[0002] A silo is a device for storing materials (such as powder materials or granular materials). In the fields of material transmission and material transfer, as a carrier of materials, a silo can accommodate and buffer materials. In the prior art, materials are put into the silo from the upper part of the silo and discharged through a silo discharging port at the lower part of the silo. At the same time, the silo discharging port is connected to other transmission devices to facilitate the materials to enter the subsequent process equipment, such as a conveyor belt, a conveying screw, etc. At present, the discharging system of the silo adopts a valve discharging structure, and discharges materials from an opening at the bottom of the silo for conveying.

[0003] However, during the discharging process of the silo, the small opening at the bottom of the silo is prone to blockage, resulting in abnormal feeding and discharging, which affects the subsequent production; manual intervention is required to unblock the blockage; moreover, the valve control is inaccurate and the discharging amount cannot be accurately controlled. Summary of the Utility Model

[0004] In order to solve the problems that the bottom of the silo is prone to blockage during the discharging process and it is difficult to control the discharging amount, the utility model provides a discharging and conveying device at the bottom of a silo.

[0005] The utility model provides a discharging and conveying device at the bottom of a silo, which comprises a feeding component, a conveying mechanism and a scraping component;

[0006] The feeding component comprises a bracket and a silo body arranged on the bracket. An outlet is arranged at the bottom of the silo body. The outlet is rectangular. An opening is arranged at the bottom of the side wall of the silo body;

[0007] The conveying mechanism comprises a conveyor belt which is of a scale plate type;

[0008] The scraping component comprises a cylinder and a sliding plate which are both arranged on the silo body. The output end of the cylinder is connected to the top end of the sliding plate. The sliding plate is used to block the opening. A discharging gap is formed between the bottom end of the sliding plate and the conveyor belt.

[0009] By adopting the above technical solution, a large-area rectangular opening at the bottom of the silo body, combined with the transportation of the scale plate type conveyor belt, can effectively reduce the probability of blockage at the bottom of the silo during the feeding process; if the material is blocked on the conveyor belt at the discharge port, the cylinder can be activated to move the slide plate upward, increasing the size of the discharge gap formed between the slide plate and the conveyor belt and increasing the discharge height, which can further reduce the probability of blockage at the bottom of the silo during the feeding process; moreover, during the transportation of the material, the cylinder can be activated to move the slide plate, control the discharge gap, further control the discharge height, and at the same time control the discharge speed of the conveyor belt. The two cooperate with each other to achieve the effect of accurately controlling the discharge volume.

[0010] Optionally, the bottom end of the slide plate is concavely provided with a concave cavity extending along the transverse direction.

[0011] Optionally, the bottom of the silo body is provided with a feeding section inclined towards the moving direction of the conveyor belt.

[0012] Optionally, the slide plate is slidably installed on the feeding sections on both longitudinal sides of the opening by configuring slide rails, and the slide plate is slidably attached to the side wall of the feeding section.

[0013] Optionally, baffles are installed on both sides of the conveyor belt.

[0014] Optionally, the conveying mechanism further includes a frame and two conveyor shafts installed on the frame, and the conveyor belt is sleeved on the two conveyor shafts.

[0015] Optionally, a motor is installed on the frame, and the output end of the motor is connected to the conveyor shaft on one side of the frame.

[0016] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0017] 1. A large-area rectangular opening at the bottom of the silo body, combined with the transportation of the scale plate type conveyor belt, can effectively reduce the probability of blockage at the bottom of the silo during the feeding process.

[0018] 2. If the material is blocked on the conveyor belt at the discharge port, the cylinder can be activated to move the slide plate upward, increasing the size of the discharge gap formed between the slide plate and the conveyor belt and increasing the discharge height, which can further reduce the probability of blockage at the bottom of the silo during the feeding process; moreover, during the transportation of the material, the cylinder can be activated to move the slide plate, control the discharge gap, further control the discharge height, and at the same time control the discharge speed of the conveyor belt. The two cooperate with each other to achieve the effect of accurately controlling the discharge volume. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] The following will Figures 1 - 3 further describe the present utility model in detail.

[0024] This embodiment discloses a discharge and conveying device for the bottom of a silo: Refer to Figures 1 - 3 , a discharge and conveying device for the bottom of a silo includes a blanking component 10, a conveying mechanism 20 and a scraper assembly 30;

[0025] The blanking component 10 includes a bracket 11 and a silo body 12 arranged on the bracket 11. The bottom of the silo body 12 is provided with a discharge port 121, the discharge port 121 is rectangular, and an opening 122 is provided at the bottom of the side wall of the silo body 12;

[0026] The conveying mechanism 20 includes a conveyor belt 21, and the conveyor belt 21 is of the scale plate type;

[0027] The scraper assembly 30 includes a cylinder 31 and a skateboard 32 both arranged on the silo body 12. The output end of the cylinder 31 is connected to the top end of the skateboard 32. The skateboard 32 is used to block the opening 122, and a discharge gap 33 is formed between the bottom end of the skateboard 32 and the conveyor belt 21.

[0028] The large-area rectangular opening 122 at the bottom of the silo body 12, combined with the conveying of the scale plate type conveyor belt 21, can effectively reduce the probability of blockage at the bottom of the silo during the blanking process; if the material is blocked on the conveyor belt 21 at the discharge port 121, the cylinder 31 can be started to move the skateboard 32 upward, increasing the size of the discharge gap 33 formed between the skateboard 32 and the conveyor belt 21, increasing the discharge height, and further reducing the probability of blockage at the bottom of the silo during the blanking process; moreover, during the conveying of the material, the cylinder 31 can be started to move the skateboard 32, controlling the discharge gap 33, further controlling the discharge height, and at the same time controlling the discharge speed of the conveyor belt 21. The two cooperate with each other to achieve the effect of accurately controlling the discharge amount.

[0029] Refer to Figure 1 , baffles 211 are installed on both sides of the conveyor belt 21.

[0030] To prevent the materials placed on the conveyor belt 21 from overflowing under the action of gravity, baffles 211 are installed on both sides of the conveyor belt 21. The materials will come into contact with the baffles 211 during the conveying process, making it difficult for them to overflow.

[0031] Refer to Figure 1 As shown, the conveying mechanism 20 further includes a frame 22 and two conveyor shafts 23 installed on the frame 22. The conveyor belt 21 is sleeved on the two conveyor shafts 23. A motor 24 is installed on the frame 22, and the output end of the motor 24 is connected to the conveyor shaft 23 on one side of the frame 22.

[0032] Start the motor 24, the conveyor shaft 23 rotates, and drives the conveyor belt 21 to move, which is used to convey materials.

[0033] Refer to Figures 1 - 2 As shown, a blanking section 123 inclined towards the moving direction of the conveyor belt 21 is provided at the bottom of the bin body 12.

[0034] The setting of the blanking section 123 inclined towards the moving direction of the conveyor belt 21 enables the materials to fall towards the moving direction of the conveyor belt 21 under the action of inertia during the discharging process, reducing the probability of the materials overflowing or splashing away from the moving direction of the conveyor belt 21 during the blanking process and improving the transmission efficiency of the conveyor belt 21.

[0035] Refer to Figures 1 - 2 As shown, sliding plates 32 are slidably installed on the blanking sections 123 on both longitudinal sides of the opening 122 by configuring slide rails, and the sliding plates 32 are slidably attached to the side walls of the blanking sections 123.

[0036] The setting of the slide rails is used to reduce the probability of the sliding plates 32 shaking during the movement; during the conveying process of the materials, the sliding plates 32 will inevitably stick to the materials. Start the cylinder 31, move the sliding plates 32 upward, and the sliding plates 32 are slidably attached to the side walls of the blanking sections 123, which can scrape off the attached materials and reduce waste.

[0037] Refer to Figure 3 As shown, a concave cavity 321 extending in the transverse direction is concavely provided at the bottom end of the sliding plate 32.

[0038] The concave cavity 321 provided at the bottom end of the sliding plate 32 is used to eliminate the tension caused by the relatively high position of the materials in the blanking section 123, avoid the phenomena of vortex and upwelling of the materials, and thus ensure the homogeneity of the discharging height, solving the problem of difficultly ensuring the homogeneity of the discharging height.

[0039] The above are all preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
