[0003] In the existing technology, during the transportation process, the ash blocks may fall off into fragments and powder due to equipment vibration or insufficient compactness of the ash blocks themselves. These fragments and powder will be transported to the next process along with the transmission equipment, affecting the normal drying operation of the next process. Manually sorting these fragments and powder will increase the labor intensity of workers and reduce production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide an ash block transmission and screening device, aiming to solve the problem that manual sorting of broken blocks and powder materials increases the labor intensity of workers and reduces production efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide an ash block transmission and screening device, including a first transmission mechanism, a second transmission mechanism and a screening mechanism, the first transmission mechanism and the second transmission mechanism are arranged in sequence, and the discharge end of the first transmission mechanism is higher than the feed end of the second transmission mechanism, the screening mechanism includes an inclined guide screening plate, the guide screening plate is inclined downward from the discharge end of the first transmission mechanism to the feed end of the second transmission mechanism, a plurality of screening holes are provided on the upper part of the guide screening plate, a collection box is provided below the guide screening plate, an inclined guide plate is connected to the middle part of the lower end of the guide screening plate, the inclined guide plate is inclined from top to bottom toward the collection box, and the inclined guide plate is used to receive the fragments or powder falling through the plurality of screening holes and guide them into the collection box.

[0007] In one possible implementation, upper springs are connected on both sides of the upper end of the inclined material guide plate, and the two upper springs are connected to both sides of the first transmission mechanism near the discharge end; lower springs are connected on both sides of the middle part of the inclined material guide plate, and the two lower springs are connected to both sides of the second transmission mechanism near the feed end.

[0008] In a possible implementation, support rods are longitudinally provided on both sides of the second transmission mechanism close to the feed end, and the two lower springs are respectively connected to the two support rods.

[0009] In a possible implementation, a guide section is provided at the lower portion of the guide screening plate, and the width of the guide section gradually decreases from top to bottom.

[0010] In a possible implementation, the screening holes are strip-shaped holes, the strip-shaped holes are arranged longitudinally along the guide screening plate, and a plurality of the strip-shaped holes are arranged at equal intervals along the width direction of the guide screening plate.

[0015] The beneficial effect of the ash block transmission and screening device provided by the present invention is that, compared with the prior art, the ash block is transported by the first transmission mechanism and falls onto the upper end surface of the guide screening plate. When the ash block falls from the first transmission mechanism to the upper end surface of the guide screening plate, some fragments and powder will fall onto the upper end surface of the guide screening plate at the same time. The ash block falls downward along the upper end surface of the guide screening plate along with the fragments and powder. Since the fragments and powder are relatively small in volume, when passing through multiple screening holes, the fragments and powder will pass through the screening holes and fall onto the upper end surface of the inclined guide plate, and then slide along the inclined guide plate into the collection box for unified collection.

[0024] See also Figure 1 and Figure 2 Now, the ash block transmission and screening device provided by the utility model is described. The ash block transmission and screening device includes a first transmission mechanism 100, a second transmission mechanism 200 and a screening mechanism. The first transmission mechanism 100 and the second transmission mechanism 200 are arranged in sequence, and the discharge end of the first transmission mechanism 100 is higher than the feed end of the second transmission mechanism 200. The screening mechanism includes an inclined guide screening plate 300. The guide screening plate 300 is inclined downward from the discharge end of the first transmission mechanism 100 to the feed end of the second transmission mechanism 200. A plurality of screening holes 310 are opened on the upper part of the guide screening plate 300. A collection box 400 is arranged below the guide screening plate 300. An inclined guide plate 320 is connected to the middle part of the lower end of the guide screening plate 300. The inclined guide plate 320 is inclined from top to bottom toward the collection box 400. The inclined guide plate 320 is used to receive the fragments or powder falling through the plurality of screening holes 310 and guide them into the collection box 400.

[0025] Compared with the prior art, the ash block transmission and screening device provided by the present invention is characterized in that the ash blocks are transported by the first transmission mechanism 100 and fall onto the upper end surface of the guide screening plate 300. When the ash blocks fall from the first transmission mechanism 100 onto the upper end surface of the guide screening plate 300, some fragments and powder will also fall onto the upper end surface of the guide screening plate 300. The ash blocks, along with the fragments and powder, fall downward along the upper end surface of the guide screening plate 300. Due to their small size, the fragments and powder will pass through the screening holes 310 and fall onto the upper end surface of the inclined guide plate 320 after passing through the plurality of screening holes 310. They will then slide along the inclined guide plate 320 and fall into the collection box 400 for unified collection. Due to their large size, the ash blocks can smoothly pass through the guide screening plate 300 and fall onto the second transmission mechanism 200. They are then transported by the second transmission mechanism 200 to the next process for drying. The ash block transmission and screening device provided by the utility model can automatically remove broken pieces and powder mixed in the ash block without manual sorting and removal, thereby reducing the labor intensity of workers and improving production efficiency.

[0026] See also Figure 1 The first transmission mechanism 100 includes a first transmission frame 110, a first transmission belt 120 and a first drive motor 130. The first transmission belt 120 is arranged on the first transmission frame 110. The upper end of the inclined guide plate 320 is hinged to the side of the first transmission frame 110 close to the discharge end. The first drive motor 130 is installed on the side of the first transmission frame 110 close to the discharge end through a mounting base. The driving end of the first drive motor 130 is connected to the rotation of the first transmission belt 120 by means of a belt. The first drive motor 130 is used to drive the first transmission belt 120 to operate, thereby realizing the transportation of ash blocks on the first transmission belt 120.

[0027] Upper springs 330 are connected to the upper ends of the inclined guide plate 320. These two upper springs 330 are connected to the two sides of the first conveyor mechanism 100 near the discharge end. Lower springs 340 are connected to the middle of the inclined guide plate 320. These two lower springs 340 are connected to the two sides of the second conveyor mechanism 200 near the feed end. Support rods 350 are longitudinally arranged on both sides of the second conveyor mechanism 200 near the feed end. The two lower springs 340 are connected to these two support rods 350.

[0028] Connecting rods extending downward are connected to both sides of the first conveyor frame 110 near the discharge end. Loops are located at the ends of the two connecting rods. Loops are also located on both sides of the upper end of the inclined guide plate 320. The upper and lower ends of the two upper springs 330 are respectively attached to the corresponding loops. Similarly, the upper ends of the two support rods 350 are also attached to loops. Loops are also located on both sides of the middle portion of the inclined guide plate 320. The upper and lower ends of the two lower springs 340 are respectively attached to the corresponding loops. When ash blocks, along with fragments or powder, fall onto the inclined guide plate 320, the two upper springs 330 and two lower springs 340 drive the inclined guide plate 320, making it easier for the ash blocks to slide onto the second conveyor mechanism 200 and for fragments or powder to fall through the screening holes 310.

[0029] See also Figure 1 and Figure 2 A guide section 360 is provided at the bottom of the guide screening plate 300. The guide section 360 is integrally formed at the bottom of the guide screening plate 300. The guide section 360 is a plate structure whose width gradually decreases from top to bottom, thereby reducing the space below the guide screening plate 300. Preferably, baffles can be provided on both sides of the guide section 360 to guide the ash blocks to accurately fall onto the second conveying mechanism 200.

[0030] See also Figure 2 The screening holes 310 are strip-shaped holes, arranged longitudinally along the guide screen plate 300, and are evenly spaced across the width of the guide screen plate 300. The strip-shaped holes cover the entire upper area of ​​the guide screen plate 300. As crushed or powdered material slides down the upper surface of the guide screen plate 300, it more easily passes through the strip-shaped screening holes 310 and falls onto the inclined guide plate 320, ultimately falling into the collection bin 400 for collection.

[0031] Preferably, side plates 370 are provided on either side of the lower end of the guide screening plate 300. The two side plates 370 are provided on either side of the inclined guide plate 320 to prevent debris or powder from falling from either side of the inclined guide plate 320. The two side plates 370, the inclined guide plate 320, and the guide screening plate 300 form a space open to the rear. As debris or powder slides down the inclined guide plate 320, the two side plates 370 can block the debris or powder, preventing it from falling from either side of the inclined guide plate 320 onto the ground and becoming difficult to collect.

[0032] The upper end of the inclined guide plate 320 is hinged to the middle of the lower end of the guide screening plate 300. Specifically, the upper ends of the inclined guide plate 320 are connected by locking bolts, which can adjust the inclination angle of the inclined guide plate 320 to facilitate matching the position of the collection box 400.

[0033] The second conveyor mechanism 200 includes a second conveyor frame 210, a second conveyor belt 220, and a second drive motor (not shown). The second conveyor frame 210 includes horizontal sections at both ends and an inclined section 230 in the middle. The second conveyor belt 220 is configured to be mounted on the second conveyor frame 210, thus comprising horizontal sections at both ends and an inclined section 230 in the middle. The inclined section 230 slopes upward from bottom to top along the conveying direction. During transport along the inclined section 230, any debris that does not pass through the sieve holes 310 (the majority of the powdered material can pass through the sieve holes 310) will slide onto the horizontal section in front of the inclined section 230, facilitating collection and preventing it from entering the next process.

[0034] The bottom of the material collection box 400 is provided with a plurality of support ribs 410 at intervals, and the plurality of support ribs 410 are welded to the bottom surface of the material collection box 400. Support gaps are formed between adjacent support ribs 410, and the fork tines of a forklift are inserted into the support gaps to facilitate the movement of the material collection box 400.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
