However, the dust removal equipment of the device can only clean the dust floating after falling into the buffer hopper, and the dust adsorbed on part of the grain cannot effectively fall and float to the dust removal equipment, causing the part of the grain not to be dusted, so that the subsequent grain will float to the outside when discharged to the transportation tool, causing pollution.

[0004] Therefore, the utility model is proposed. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0031] The present application will now be further described in detail with reference to the accompanying drawings.

[0032] Please refer to Figures 1-5 As shown in the figure, in this embodiment, a bulk grain dispensing device with dust suppression structure is provided, which comprises a cylinder 1 installed at the discharge end of a material conveying device, a receiving hopper 5 and a discharge hopper 7 are connected to the upper and lower ends of the cylinder 1, a plurality of partition plates 8 are arranged in the cylinder 1 in a staggered manner, the partition plates 8 form an N-shaped channel inside the cylinder 1, a plurality of guide grooves 20 in a serpentine structure are embedded in the partition plates 8, a plurality of collection boxes 13 are fixedly installed on the inner wall of the cylinder 1 at the communication between adjacent partition plates 8, the collection boxes 13 are hollow inside, a plurality of through holes 14 are provided through the collection boxes 13 relative to the partition plates 8, a mounting plate 11 is fixedly connected to the outer wall of the cylinder 1, a dust suction fan 3 is fixedly connected to the mounting plate 11, the air inlet of the dust suction fan 3 is communicated with the collection boxes 13, a cleaning assembly 9 is communicated with the air outlet of the dust suction fan 3, and the cleaning assembly 9 is fixedly installed on the mounting plate 11.

[0033] Specifically, the conveying equipment conveys the bulk grain to the receiving hopper 5 at the top of the cylinder 1. After the bulk grain enters the cylinder 1, the bulk grain changes its trajectory and reduces its speed when flowing in the N-shaped channel formed by the multiple relatively staggered baffles 8 in the cylinder 1, thereby reducing the dust flying caused by direct falling or rapid flowing. At the same time, the serpentine guide groove 20 embedded on the baffle 8 further guides the bulk grain to move slowly along a specific path, so that the collision and friction between the grains and between the grains and the inner wall of the cylinder 1 are more moderate, thereby inhibiting dust generation. The inner wall of the cylinder 1 at the communication between the adjacent baffles 8 is fixed with a collection box 13. Under the action of the dust suction fan 3, negative pressure is generated in the cylinder 1, the dust is sucked into the collection box 13 through the through hole 14 on the collection box 13, and then is transported to the cleaning assembly 9 for purification treatment. Finally, the bulk grain is discharged along the discharge hopper 7 to the loading equipment. Through the special structure of the baffle 8, the amount of dust generated during the bulk grain delivery process is effectively reduced, the grain loss and environmental pollution are reduced, the generated dust can be collected in time to prevent the dust from spreading in the cylinder 1, and at the same time, a large amount of dust generated when the bulk grain is discharged to other loading equipment is reduced, the working environment is relatively clean, and the health of the operators is beneficial.

[0034] It should be noted that in the present embodiment, the conveying equipment of the bulk grain delivery device can refer to the disclosure document with the patent publication number CN220222795U. The discharge end of the conveying equipment is installed at the position of the receiving hopper 5. At the same time, the dust removal equipment described in the disclosure document can also be installed at the position of the receiving hopper 5 to achieve further dust suppression effect. At the same time, the discharge end of the discharge hopper 7 can also be installed with a dust suppression chute to facilitate the discharge of the bulk grain. Further, the installation and structure of the dust suction fan 3 are prior art. The collection box 13 has a hollow cavity with a gradually decreasing cross-sectional area from the through hole 14 to the air inlet of the dust suction fan 3 and a funnel-shaped structure.

[0035] In the present embodiment, as shown in Figure 1 and Figure 5As shown, the cleaning assembly 9 includes a cleaning box 91, and a filter screen 92, a filter cloth layer 94, a sponge layer 93 and an activated carbon layer 95 arranged in sequence from one end of the cleaning box 91 to the exhaust port of the dust extraction fan 3. The cleaning box 91 is provided with an air outlet 12 penetrating through the activated carbon layer 95. The cleaning box 91 includes a box body 911 and a box cover 912 connected detachably. The air outlet 12 is provided on the box cover 912. The box body 911 is fixedly connected with a flow guide hopper 21 communicating with the exhaust port of the dust extraction fan 3 inwardly to the filter screen 92. The flow guide hopper 21 is in a funnel type structure with the cross-sectional area gradually increasing from the exhaust port of the dust extraction fan 3 to the filter screen 92. Specifically, the dust extraction fan 3 draws the air containing dust into the cleaning assembly 9. The air first passes through the filter screen 92, which preliminarily filters out the larger impurities and part of the dust. Then the air passes through the filter cloth layer 94, the sponge layer 93 and the activated carbon layer 95 in sequence. The filter cloth layer 94 further filters the fine dust. The sponge layer 93 can absorb some moisture and small particles. The activated carbon layer 95 is mainly used for adsorbing odors and harmful gases in the air. After being purified by multiple layers, the clean air is discharged from the air outlet 12. The multi-layer structure of the cleaning assembly 9 can efficiently purify the dust-containing air, ensure that the discharged air meets the environmental protection requirements, and reduce the pollution to the surrounding environment. The box body 911 and the box cover 912 are detachably connected, which facilitates the regular replacement and cleaning of the filter screen 92, the filter cloth layer 94, the sponge layer 93 and the activated carbon layer 95 inside the cleaning box 91.

[0036] In this embodiment, as shown in Figure 3 and Figure 4 Each of the plurality of partitions 8 is fixedly connected with a sliding block 15.

The cylinder 1 is fixedly installed with a vibration motor 18 driving the plurality of partitions 8 to vibrate. Specifically, the sliding block 15 on the plurality of partitions 8 slides in the sliding groove 16 in the cylinder 1, ensuring that the partition 8 can stably move up and down when vibrating. The vibration motor 18 drives the partition 8 to vibrate, causing the dust adhering to the partition 8 to fall off, facilitating the dust to be sucked into the collection box 13 by the dust extraction fan 3. At the same time, vibration also helps the movement of the scattered grains on the partition 8, preventing the grains from blocking the guide groove 20. The adjacent partitions 8 are connected through the connecting plate 17, ensuring the coordination of the vibration of the plurality of partitions 8. Further, the cylinder 1 is fixedly connected with a fixed plate 19 near the discharge hopper 7 at the bottom. The fixed plate 19 plays a blocking role, which can prevent the scattered grains from falling to the bottom of the cylinder 1.
