Description

Technical Field

[0001] The utility model belongs to the technical field of bucket elevators, and in particular relates to a bucket structure with adjustable volume and easy material discharge. Background Art

[0002] A bucket elevator is a device used to vertically lift bulk materials and is widely used in various industrial production lines. It lifts materials through a series of hoppers, which scoop them from a storage tank below. The hoppers are then lifted to the top by a conveyor belt or chain. After passing over the top wheel, the bucket elevator tilts downward and dumps the material into a receiving trough. However, when the hopper of a traditional bucket elevator transports sticky materials or materials with a high moisture content, the material will adhere to the inner wall of the hopper and will not separate from the hopper during discharge. This reduces discharge efficiency and, more seriously, may cause the motor to operate at excessive power, causing damage.

[0003] Chinese patent publication number CN221252669U discloses an elevator powder hopper, comprising an elevator, a mounting frame mounted at the conveying end of the elevator, a hopper body removably mounted on the upper surface of the mounting frame, a mounting plate fixedly connected to the inner wall of the hopper body, a mounting hole formed in the upper surface of the mounting plate, a sleeve fixedly connected to the inner wall of the mounting hole, a first spring fixedly connected to the inner bottom wall of the sleeve, a T-shaped connecting rod fixedly connected to the top of the first spring, the surface of the T-shaped connecting rod overlapping the inner wall of the sleeve, a receiving bucket fixedly connected to the top of the T-shaped connecting rod, and a vibration motor fixedly connected to the lower surface of the receiving bucket. The elevator powder hopper is configured such that material is loaded into the receiving bucket, the elevator is activated to lift the hopper body, and when the hopper body tilts and falls, the vibration motor is activated, causing the receiving bucket to vibrate. The vibration of the receiving bucket can shake off material accumulated and attached to the receiving bucket, thereby ensuring complete material discharge.

[0004] Although the vibration motor in the above patent solution provides vibration for the hopper, which can reduce the accumulation at the bottom of the elevator to a certain extent, the addition of the corresponding vibration motor also means the addition of corresponding circuit wiring and control program, which increases the overall manufacturing cost and structural complexity. However, in a large part of the use scenario, the hopper does not require continuous high-frequency or low-frequency vibration. Only knocking or a single vibration is sufficient to remove the accumulated materials. The use of a vibration motor, on the contrary, excessively increases the cost and control difficulty. Therefore, the cost-effectiveness of the above patent solution is not high. Utility Model Content

[0005] In order to overcome the technical problem in the prior art that when transporting part of the material, continuous high-frequency or low-frequency vibration is not required, and only a single knock or vibration is sufficient to release the material from the hopper, thus resulting in a low cost-effective technical problem of the vibration motor. One purpose of the utility model is to provide a hopper structure with adjustable volume and easy material discharge. By sliding the hopper to a conveying mounting plate, when the hopper is turned downward for conveying, the hopper slides downward a short distance under the action of gravity, generating vibration to release the material from the hopper, thereby preventing the accumulation of materials at the bottom of the hopper in a low-cost manner.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a hopper structure with adjustable volume and easy unloading, including a conveying mounting plate, which is arranged on the conveying chain of the elevator; a hopper, the hopper is slidably connected to the conveying mounting plate, and the sliding direction of the hopper is arranged along the movement direction of the conveying chain; wherein, the hopper is provided with a plurality of hooks at one end facing the conveying mounting plate; the conveying mounting plate is provided with a plurality of hanging holes at one end facing the hopper; each of the hooks is slidably connected in the corresponding hanging hole; a plurality of limit screws are provided on the conveying mounting plate, and the limit screws are used to adjust the sliding stroke of the hook.

[0007] The hook is hung in the hanging hole to achieve quick loading and unloading of the hopper, making it easy to adjust and replace the hopper. At the same time, the limit screw can adjust the sliding stroke of the hopper, that is, adjust the vibration intensity of the hopper. According to different transport materials, the vibration intensity can be minimized while ensuring sufficient vibration intensity to release the material from the hopper, effectively extending the service life of the hopper and the conveyor chain.

[0008] Furthermore, the hopper includes a fixed hopper, which is slidably connected to the conveying mounting plate; a sliding hopper, which has two sliding hoppers and is slidably connected to the two ends of the fixed hopper respectively; wherein the sliding direction of the sliding hopper is perpendicular to the sliding direction of the fixed hopper; the fixed hopper and the sliding hopper are combined to form a material holding cavity with an open upper end.

[0009] The volume of the material holding chamber can be adjusted by the relative sliding of the sliding and fixed hoppers. When transporting materials of varying densities, the transport weight of the hopper can be adjusted to ensure that the conveyor chain is always within the rated operating power, helping to extend the service life of the conveyor chain. Furthermore, the material holding chamber can be filled with as much material as possible at the rated operating power, thereby improving conveying efficiency.

[0010] Specifically, the fixed bucket is a concave metal plate with an opening facing upward; the sliding bucket is provided with a plug-in groove at one end facing the fixed bucket; and the fixed bucket is slidably connected in the plug-in groove.

[0011] Specifically, a plurality of locking screws are provided on the upper end of the sliding bucket; the locking screws penetrate into the plug-in slots and abut against the fixed bucket.

[0012] Preferably, both ends of the opening of the fixing bucket are respectively provided with positioning holes arranged along a linear pattern; the locking screws can be selectively inserted into the corresponding positioning holes.

[0013] The locking screws and the positioning holes facilitate accurate adjustment of the relative positions of the sliding bucket and the fixed bucket. On the one hand, the volume of the material holding chamber can be intuitively measured according to the position of the inserted positioning holes; on the other hand, it is also convenient to adjust the extended length of the two sliding buckets so that the counterweights at both ends of the fixed bucket are equal, so that the force of the conveying chain is along the conveying direction, thereby improving the conveying stability and service life.

[0014] Furthermore, a rectangular shell is provided at one end of the conveying mounting plate facing the hopper; there are two limit screws, which are symmetrically arranged at the upper end of the rectangular shell; there are four hanging holes, which are provided at one end of the rectangular shell facing the hopper; and there are two longitudinally arranged hanging holes under each limit screw.

[0015] Specifically, two reinforcing ribs are longitudinally provided at one end of the hopper facing the conveying mounting plate; two hooks are provided at one end of the reinforcing rib facing the conveying mounting plate; and the longitudinal length of the hook is equal to the longitudinal length of the hanging hole.

[0016] Specifically, two welding nuts are symmetrically arranged on the upper end of the rectangular shell; the limiting screw is arranged in the welding nut; the sliding stroke of the hook is limited by installing the limiting screws of different lengths.

[0017] Specifically, two anti-loosening washers are arranged between the welding nut and the nut of the limit screw; ratchets are arranged on the anti-loosening washers; and the ratchets on two adjacent anti-loosening washers are facing each other.

[0018] Preferably, a vibration motor is provided at the lower end of the hopper.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The hopper is slidably connected to the conveying mounting plate. When the hopper flips downward to pour out the conveyed material, the hopper slides downward rapidly under the action of gravity and collides with the hanging hole, which will generate vibration on the hopper. With extremely low cost and streamlined structure, it can prevent the conveyed material from accumulating at the bottom of the hopper.

[0021] 2. The sliding distance of the hopper can be adjusted, that is, the intensity of vibration can be adjusted. Under the premise of ensuring sufficient vibration intensity to separate the accumulated materials, the vibration intensity can be reduced as much as possible. In addition, the sliding distance can be adjusted to zero, that is, when conveying materials that will not cause accumulation, the hopper can be directly fixed without vibration, which helps to extend the service life of the conveyor chain and the elevator.

[0022] 3. The volume of the hopper can be adjusted through the relative sliding of the fixed bucket and the sliding bucket. When conveying low-density materials, the volume can be expanded to increase the conveying efficiency; when conveying high-density materials, the volume can be reduced to control the conveying quality within the rated power of the elevator, thereby improving the safety of the elevator.
