Description

Technical Field

[0001] This utility model relates to the field of material transport equipment, specifically to a retractable mobile receiving hopper device. Background Technology

[0002] Belt conveyors are frequently used during grain storage, employing a method of connecting one conveyor to another. For convenient unloading, a receiving hopper is installed at the low-level receiving port of each conveyor. During operation, as grain falls parabolically from the high-level feeding port of one conveyor to the low-level receiving port of another, the sidewalls of the typical receiving hopper are too shallow. In windy conditions, the conveyed grain can be blown onto the ground. Furthermore, the movement of vehicles increases the breakage rate of grain on the ground, leading to more impurities and increasing the workload for workers. Utility Model Content

[0003] The purpose of this invention is to solve the problem of grain waste caused by shallow hopper depth, excessive falling impact force, and wind force during grain transportation.

[0004] The present invention adopts the following technical solution: A retractable mobile receiving hopper device is disposed above one end of a grain conveyor belt. The mobile receiving hopper device includes a retractable receiving hopper that can extend and retract in a vertical direction, a moving component for driving the retractable receiving hopper to move in the conveying direction of the grain conveyor belt, and a control component. The retractable receiving hopper includes a receiving base frame, and several retractable receiving frames are sequentially sleeved on the receiving base frame from bottom to top. A lifting component is fixedly installed on the receiving base frame, and the output end of the lifting component is fixedly connected to the uppermost retractable receiving frame. The control component is electrically connected to the moving component and the lifting component respectively.

[0005] Furthermore, the lifting assembly consists of two lifting cylinders, which are respectively arranged on both sides of the telescopic receiving hopper.

[0006] Furthermore, the moving component includes several moving wheels and at least one moving cylinder. Moving tracks that cooperate with the moving wheels are provided on both sides of the grain conveyor belt along the conveying direction. The moving wheels are installed at the bottom of the receiving base frame. A fixed mounting seat is provided above the end of the grain conveyor belt. The moving cylinder is mounted on the fixed mounting seat. The output shaft of the moving cylinder is fixedly connected to the receiving base frame.

[0007] Furthermore, the receiving base frame is equipped with a vacuum cleaner for collecting dust, and the suction port of the vacuum cleaner is connected to the receiving base frame.

[0008] Furthermore, the telescopic receiving hopper contains at least one fence component.

[0009] Furthermore, there are two fence components: one fence component is located inside the bottom receiving frame, and the other fence component is located inside the uppermost telescopic receiving frame.

[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. This utility model adopts a telescopic receiving hopper with several telescopic sections. During use, the telescopic receiving hopper can be extended to a suitable height according to the height of the grain thrown during operation and the wind conditions, which reduces the grain from being spilled onto the ground when thrown, and also reduces the problem of increased impurities caused by vehicles running back and forth at the work site. At the same time, it also reduces the workload of workers repeatedly cleaning up the spilled grain.

[0011] 2. The telescopic receiving hopper of this utility model is equipped with a moving component. On-site operators can adjust the position of the telescopic receiving hopper on the grain conveyor belt according to the actual height of the grain discharge and the position of the grain drop point on the grain conveyor belt.

[0012] 3. This utility model also includes a dust collector, which sucks the dust generated when the grain falls into the telescopic receiving hopper during the grain scattering process into a cloth bag. After the operation is completed, the impurities are cleaned in time, which can reduce the impurities in the grain and reduce dust pollution of the surrounding environment, thus achieving the purpose of energy saving, consumption reduction and environmental protection.

[0013] 4. The telescopic receiving hopper of this utility model is equipped with two grid components, and the height of one of the grid components can change with the height of the telescopic receiving hopper. This allows it to work with different grain drop points to indirectly buffer the grain and reduce the loss of grain falling from a height. It can also serve as a double-layer filter to further reduce large impurities or large clumps in the grain. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] Figure 2 This is a top view of the telescopic receiving hopper of this utility model.

[0016] The components in the diagram are labeled as follows: telescopic receiving hopper 10, receiving base frame 11, telescopic receiving frame 12, lifting cylinder 13, moving component 20, moving wheel 21, moving cylinder 22, vacuum cleaner 30, fence component 40, grain conveyor belt 50, and moving track 51. Detailed Implementation

[0017] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0018] Reference Figure 1A retractable mobile receiving hopper device is disposed above one end of a grain conveyor belt 50, and includes a retractable receiving hopper 10, a moving component 20, a vacuum cleaner 30, and a control component.

[0019] Reference Figure 1 The telescopic receiving hopper 10 can extend and retract along the vertical direction of the grain conveyor belt 50. The telescopic receiving hopper 10 includes a receiving bottom frame 11, and several telescopic receiving frames 12 are sequentially sleeved on the receiving bottom frame 11 from bottom to top. A lifting component is fixedly installed on the receiving bottom frame 11, and the output end of the lifting component is fixedly connected to the uppermost telescopic receiving frame 12.

[0020] Specifically, refer to Figure 1 and Figure 2 The receiving base frame 11 is made of steel alloy and has a square frame structure that is wider at the top and narrower at the bottom. The telescopic receiving frame 12 is also made of steel alloy and adopts a commercially available square telescopic sleeve structure. Both the receiving base frame 11 and the telescopic receiving frame 12 have only four sides and no top and bottom sides. The lifting assembly consists of two lifting cylinders 13, which are respectively installed on the two side walls of the receiving base frame 11. The output ends of the two lifting cylinders 13 are respectively fixedly connected to the two side walls of the uppermost telescopic receiving frame 12. This utility model can control the telescopic height of the telescopic receiving hopper 10 through the lifting cylinders 13. During operation, it can be extended to a suitable height according to actual needs. This prevents the grain thrown over (because the raw material hopper body is too shallow) from being blown by the wind or thrown to the ground, reduces the increase of impurities caused by the grain being crushed by the operating vehicle, thereby reducing grain loss and also reducing the workload of workers repeatedly cleaning up the grain on the ground.

[0021] Reference Figure 1 and Figure 2The moving component 20 includes several moving wheels 21 and at least one moving cylinder 22. Moving tracks 51, cooperating with the moving wheels 21, are provided on both sides of the grain conveyor belt 50 along the conveying direction. Fixed mounting seats are provided above both ends of the grain conveyor belt 50. In this embodiment, four moving wheels 21 are installed on the bottom of the receiving base frame 11. Preferably, the moving wheels 21 are braked moving wheels 21 with brake components. These braked moving wheels 21 are commercially available products, and their structure will not be described in detail here. Their brake components can control the telescopic receiving hopper 10 to lock and fix it at a suitable position on the moving tracks 51 on both sides of the grain conveyor belt 50 at any time. Two moving cylinders 22 are installed on the fixed mounting seats, and the output shafts of the moving cylinders 22 are fixedly connected to the receiving base frame 11. This utility model can control the position of the telescopic receiving hopper 10 on the grain conveyor belt 50 by moving the cylinder 22. During the grain loading and unloading operation, the on-site operators can adjust the position of the telescopic receiving hopper 10 on the grain conveyor belt 50 according to the actual height distance of the grain discharge and the position of the grain drop point on the grain conveyor belt 50.

[0022] Reference Figure 1 and Figure 2 The outer wall of the receiving base frame 11 is equipped with a dust collector 30 for collecting dust, and the suction port of the dust collector 30 is connected to the inside of the receiving base frame 11. The dust collector 30 is a commercially available small dust collector 30, including a suction motor, connecting parts, and a dust bag, etc. Its specific structure and working principle will not be described in detail here. In this utility model, when grain is thrown into the telescopic receiving hopper 10 during the loading and unloading operation, the lighter dust such as grain impurities in the hopper will be scattered and flying everywhere. This component can promptly suck most of the scattered and flying dust in the hopper into the dust bag. After the operation, the dust in the bag can be disposed of in time, which can reduce grain loss.

[0023] Reference Figure 1 and Figure 2 The telescopic receiving hopper 10 contains at least one fence component 40, preferably two in this embodiment: one fence component 40 is located in the bottom receiving frame 11, and the other fence component 40 is located in the uppermost telescopic receiving frame 12. The fence component 40 is made of steel alloy and includes an outer frame, a central grid, and other components. The grid opening diameter of this component is 2-3 cm, facilitating grain flow and preventing large impurities or lumps from entering or leaving the grain silo with the grain conveyor belt 50, thus facilitating grain storage. Furthermore, this embodiment preferably uses two fence components 40, and one of these fence components can vary in height according to the height of the telescopic receiving hopper 10, thereby indirectly buffering the grain at different drop points and reducing losses from falling grain. It also acts as a double-layer filter, further reducing large impurities or lumps in the grain.

[0024] The control component (not shown in the figure) uses an existing combination of PLC controller and remote controller. The control component is electrically connected to the moving cylinder 22 of the moving component 20, the lifting cylinder 13 of the lifting component, and the vacuum cleaner 30.

[0025] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
