Description

Technical Field

[0001] This utility model relates to the field of grain suction machine technology, and in particular to a grain suction machine with dust collection function. Background Technology

[0002] During the grain intake and transportation process, a large amount of dust, such as chaff, bran, and debris, is often generated. This dust not only pollutes the working environment and affects the health of operators (long-term inhalation may lead to respiratory diseases), but it may also adversely affect the quality of subsequent grain and processing equipment, and even cause safety hazards such as dust explosions. Existing dust control measures are often independent of the grain intake equipment or have poor dust control effects, making it difficult to achieve source control. As a result, dust control is incomplete, the dust problem remains prominent, and the working environment has not been effectively improved. Utility Model Content

[0003] The purpose of this invention is to solve the problems of existing filtration devices, which typically have limited filtration area, are prone to clogging when processing grains with high impurity content, leading to decreased grain suction efficiency. Furthermore, once the filter screen or filter bag becomes clogged, cleaning and replacement are complex, requiring the disassembly of numerous parts and consuming significant time and manpower. In addition, existing equipment often lacks flexible and adjustable filtration schemes for different types of grains (such as wheat, rice, and corn) and with varying impurity levels, making it difficult to achieve optimal filtration results by simply changing different filter media.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A grain suction machine with dust collection function includes a mobile cart with a support frame. A filter chamber is mounted on the support frame, and a dust collection device is connected to the filter chamber. The filter chamber is connected to a grain storage chamber via a first connecting pipe. The grain storage chamber has a grain outlet and a grain suction device for conveying grain is located beside it. The mobile cart also has a handle for easy pushing. The filter chamber includes an upper chamber and a lower chamber. A grain suction pipe connection port is located at the top of the upper chamber, and a dust extraction connection port is located on the lower chamber. A filter barrel is detachably installed between the upper and lower chambers. A support leg is located at the bottom of the lower chamber. The mobile cart integrates grain suction, filtration, dust collection, and grain storage functions. The handle frame facilitates manual movement, greatly improving the equipment's flexibility and applicability. It can be easily moved between different grain piles or warehouses. The dust collection device is directly connected to the filter chamber, forming an independent negative pressure dust removal air path. This means that most of the light dust, chaff, and other impurities are removed before the grain enters the storage silo, achieving source dust removal, effectively improving the working environment, and reducing dust generation in subsequent stages. When the filter canister is clogged or needs cleaning, there is no need to disassemble the entire complex piping system; simply open the upper and lower chambers to remove the filter canister. Maintenance is extremely convenient, saving time and effort. Different mesh sizes or types of filter canisters can be replaced according to the impurity content of different grain types (such as wheat, rice, and corn) to achieve the best filtration effect.

[0006] Furthermore, the filter barrel includes a cylindrical body, inside which an inclined filter plate is disposed. Both the inclined filter plate and the side wall of the cylindrical body have perforations. The presence of perforations on both the side wall and the inclined filter plate results in a filtration area far larger than a simple flat-bottomed filter screen. This significantly improves airflow permeability, reduces wind resistance, and enhances dust removal and grain suction efficiency. The inclined surface guides grain particles smoothly towards the bottom outlet, preventing them from falling in a columnar shape, increasing the area for dust adsorption and suction. It also helps prevent grain particles from clogging the perforations and has a certain self-cleaning function. Larger impurities may be blocked on the inclined plate, while fine dust is sucked away through the perforations on the side wall, achieving a finer filtration effect.

[0007] Furthermore, the grain suction device includes a fixed plate fixed to the mobile vehicle, on which a rotating motor is mounted. The rotating motor is connected to the fan via a transmission belt. The fan is connected to a second connecting pipe for conveying grain. By changing the pulley, the fan speed can be easily changed, thereby adjusting the suction force and flow rate to adapt to different working conditions. At the same time, the belt drive structure is simple, and maintenance and replacement costs are low.

[0008] Furthermore, the dust collection device has the same structure as the grain suction device, but its power is less than that of the grain suction device. The lower-powered dust collection device will not cause excessive interference to the main grain suction air path, thus ensuring the stability of the grain suction efficiency.

[0009] Furthermore, a gate valve is installed at the grain outlet, which regulates the flow rate of grain discharged from the grain storage silo. The gate valve can be adjusted infinitely or in stages to precisely control the speed and flow rate of grain discharged from the silo. This is very useful during bagging, transfer, or connection to the next process, preventing grain from gushing out or clogging. Furthermore, the bottom of the mobile vehicle is equipped with self-locking casters for easy movement and positioning.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The equipment highly integrates four core functions—grain suction, filtration, dust removal, and grain storage—into a mobile vehicle platform. The components form a coordinated operating system: the grain suction device transports grain through negative pressure, the filtration chamber and dust collection device simultaneously remove dust at the source, the grain storage chamber temporarily stores the treated clean grain, and finally, the grain is transferred through a controllable outlet. This eliminates the need for multiple independent devices and avoids the need for inter-device debugging. The entire process, from grain suction to clean storage and discharge, can be completed continuously, significantly reducing operational steps and time costs compared to traditional decentralized operation methods.

[0012] 2. Through the independent negative pressure dust removal air path of the filter chamber and dust collection device, most of the dust and chaff are removed before the grain enters the storage silo, preventing dust spread from the source. The dust concentration in the working environment can be reduced, effectively protecting the respiratory health of operators and reducing pollution to the surrounding environment. On the other hand, the equipment design fully considers the ease of operation: self-locking casters and handle frame enable flexible movement and stable positioning, detachable filter barrel simplifies the maintenance process, belt drive facilitates the adjustment of grain suction parameters, and gate valve precisely controls the grain discharge flow. Whether it is equipment transfer, daily maintenance or parameter adjustment, no professional technicians are required. Ordinary operators can get started after simple training, greatly reducing the threshold for operation.

[0013] 3. The equipment boasts exceptional adaptability to various scenarios and grain types: From a scenario perspective, the mobile vehicle equipped with self-locking casters can easily move between different locations such as warehouses, grain piles, and drying yards, adapting to various operational scenarios including small-scale family grain storage and small-to-medium-sized grain station transfers. From a grain type perspective, by changing the filter canisters of different mesh sizes / types, it can adapt to grains of different particle sizes and impurity contents, such as wheat, rice, and corn, ensuring effective filtration and dust removal. Simultaneously, the grain suction device allows for adjustment of the fan speed by changing the pulley, the dust collection device power adapts to the main grain suction air path, and the gate valve adjusts the grain discharge flow rate. This multi-dimensional adjustment capability allows the equipment to be flexibly adjusted according to actual operational needs (such as grain moisture content, conveying distance, and grain discharge docking method), avoiding the insufficient adaptability caused by a "one-size-fits-all" design. Its applicability range is far greater than that of traditional grain suction machines with fixed parameters. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Combination Figure 1-4As shown, a grain suction machine with dust collection function includes a mobile cart 1, a support frame 2 on the mobile cart 1, a filter chamber 3 mounted on the support frame 2, a dust collection device 4 connected to the filter chamber 3, and a grain storage chamber 6 connected to the filter chamber 3 via a first connecting pipe 5. The grain storage chamber 6 has a grain outlet 8 and a grain suction device 7 for conveying grain is located on its side. The mobile cart 1 is also equipped with a handle 9 for easy pushing. The filter chamber 3 includes an upper chamber 31 and a lower chamber 32. The upper chamber 31 has a grain suction pipe connection port 33 at its top, and the lower chamber 32 has a dust extraction connection port 34. A filter barrel 35 is detachably installed between the upper chamber 31 and the lower chamber 32, and a support leg 36 is located at the bottom of the lower chamber 32. This machine integrates functions such as grain suction, filtration, dust removal, and grain storage. The entire system is integrated onto a mobile vehicle and easily moved manually via a handle frame, greatly improving the equipment's flexibility and applicability. It can be easily transferred between different grain piles or warehouses. The dust collection device is directly connected to the filter chamber, forming an independent negative pressure dust removal air path. This means that most of the light dust, chaff, and other impurities are removed before the grain enters the storage silo, achieving source dust removal, effectively improving the working environment, and reducing dust generation in subsequent stages. When the filter canister is clogged or needs cleaning, there is no need to disassemble the entire complex piping system; simply open the upper and lower chambers to remove the filter canister. Maintenance is extremely convenient, saving time and effort. Different mesh sizes or types of filter canisters can be replaced according to the impurity content of different grain types (such as wheat, rice, and corn) to achieve the best filtration effect.

[0021] The filter barrel 35 includes a cylindrical body 351, inside which is an inclined filter plate 352. Both the inclined filter plate 352 and the side wall of the cylindrical body 351 have perforations 353. The perforations on both the side wall and the inclined filter plate significantly increase the filtration area compared to a simple flat-bottomed filter, greatly improving airflow, reducing wind resistance, and enhancing dust removal and grain suction efficiency. The inclined surface guides grain particles smoothly towards the bottom outlet, preventing them from falling in a columnar shape, increasing the area for dust collection, and helping to prevent grain particles from clogging the perforations. It also has a certain self-cleaning function; larger impurities may be blocked on the inclined plate, while fine dust is sucked away through the perforations on the side wall, achieving a finer filtration effect. The grain suction device 7 includes a fixed plate 7 fixed to the moving vehicle 1. 1. A rotating motor 72 is installed on the fixed plate 71. The rotating motor 72 is connected to the fan 74 via a transmission belt 73. The fan 74 is connected to a second connecting pipe 75 for conveying grain. By changing the pulley, the speed of the fan can be easily changed, thereby adjusting the suction force and flow rate to adapt to different working conditions. At the same time, the belt drive structure is simple and the maintenance and replacement costs are low. The dust collection device 4 has the same structure as the grain collection device 7, but its power is less than that of the grain collection device 7. The lower power dust collection device will not cause excessive interference to the main grain collection air path, ensuring the stability of the grain collection efficiency. A gate valve is installed at the grain outlet 8. The flow rate of grain discharged from the grain storage bin 6 can be adjusted by the gate valve. The gate valve can adjust the opening size steplessly or in stages, thereby precisely controlling the speed and flow rate of grain discharged from the grain storage bin. This is very useful when bagging, transferring, or connecting to the next process, avoiding grain gushing or clogging. The bottom of the mobile cart 1 is equipped with casters with self-locking function, which facilitates the movement and positioning of the mobile cart 1.

[0022] Working principle: Based on the type of grain to be transported (such as wheat, rice, corn) and its impurity content, select a filter barrel 35 with an appropriate mesh size or type, and install it between the upper chamber 31 and the lower chamber 32 of the filter compartment 3, ensuring good sealing of the chamber. At the same time, using the self-locking casters at the bottom of the mobile vehicle 1, push the handle frame 9 to move the equipment to the side of the target grain pile, lock the casters to complete the positioning, and prevent the equipment from sliding during operation. If it is necessary to adjust the grain suction parameters, the pulley in the grain suction device 7 that is compatible with the rotating motor 72 and the fan 74 can be replaced, and the required fan speed can be preset to match the appropriate air force and flow rate for subsequent grain suction operations. Start the rotating motor 72 and the dust collection device 4 of the grain suction device 7. The rotating motor 72 drives the fan 74 to run at high speed through the transmission belt 73. The fan 74 generates negative pressure suction, which sucks in grain particles, mixed dust, chaff, and other impurities in the grain pile through the second connecting pipe 75. The mixture of grain and impurities is then drawn into the suction pipe. The connection port 33 enters the upper chamber 31 of the filter chamber 3. At this time, the dust collection device 4 (which has the same structure as the grain collection device 7 but with lower power to avoid interfering with the main grain collection air path) forms an independent negative pressure dust removal air path in the filter chamber 3 through the dust collection connection port 34 of the lower chamber 32. After the mixture of grain and impurities enters the cylinder 351 of the filter barrel 35, it is guided by the inclined filter plate 352. The grain particles slide slowly to the bottom along the inclined surface. During the process, light dust, chaff and other impurities mixed in are sucked away by the negative pressure generated by the dust collection device 4 through the leakage holes 353 on the side wall of the cylinder 351 and the inclined filter plate 352, realizing the initial separation of "grain-impurities". Larger impurities (such as straw) are blocked by the inclined filter plate 352 and remain in the filter barrel. They are removed together with the filter barrel cleaning later, completing the source dust removal. The clean grain after dust removal in the filter chamber 3 falls from the bottom of the filter barrel 35 into the lower chamber 32, and is then transported to the grain storage silo 6 for temporary storage through the first connecting pipe 5. When the grain in the grain storage silo 6 reaches a certain amount or needs to be connected to subsequent processes (such as bagging and transfer), the gate valve at the grain outlet 8 is adjusted. The opening size of the gate valve is adjusted steplessly or in stages to precisely control the grain discharge speed and flow rate, avoiding the grain from being wasted due to an excessively large opening or blocked due to an excessively small opening. At this time, the clean grain is discharged smoothly from the grain outlet 8, completing the entire grain suction operation process of "inhalation-dust removal-storage-discharge".
