[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the bark crusher with an aggregate structure, the aggregate part is responsible for initially receiving and conveying the bark by setting the cooperation between the aggregate part and the feeding component, and the aggregate part (including the conveyor belt and the conveyor component) and the feeding component (including the scraper and the hanging rod). The aggregate part is responsible for initially receiving and conveying the bark, and the feeding component further pushes the bark, thereby increasing the conveying friction and thrust on the bark, ensuring that the bark can smoothly enter the feed port of the crushing device, thereby avoiding the problem of clogging of the feed port; secondly, a plurality of notches are arranged on the conveying component, and adjacent conveying components are fitted with each other, which is convenient for the advancement of the hanging rod and ensures the continuous and stable conveying of the bark.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The existing bark crusher is prone to accumulation of bark at the feed inlet due to the special structure of the bark and its light material, which causes blockage of the crusher feed inlet.

[0022] For this purpose, the present invention provides a bark crusher with an aggregate structure, see Figure 1 As shown, it comprises a crushing device 1, on which a feed port is arranged. A crushing roller is arranged inside the crushing device 1 for crushing the bark. A bracket 2 is arranged near the feed port, on which a gathering part 3 is arranged.

[0023] For details, see Figure 1-Figure 4 As shown, a feeding assembly 4 matched with the length of the gathering section 3 is arranged just above the gathering section 3, the gathering section 3 includes a conveyor belt 31, the conveyor belt 31 is rotatably connected to the bracket 2, the conveying direction of the conveyor belt 31 is toward the feed port, and one end of the conveyor belt 31 is located in the feed port; a plurality of groups of conveying assemblies 33 are evenly arranged on the conveyor belt 31; the feeding assembly 4 includes a mounting plate 41, lifting assemblies 42 are symmetrically arranged on both sides of the mounting plate 41, a scraper 43 is arranged below the mounting plate 41, a driving motor 48 is arranged on the mounting plate 41, the driving motor 48 drives the scraper 43 to reciprocate along the direction of the conveyor belt 31, a plurality of hanging rods 46 are arranged below the scraper 43, and a notch matched with the hanging rod 46 is arranged on the conveying assembly 33, and the hanging rod 46 drives the conveyor belt 31 to convey through the notch.

[0024] It can be seen that, since the bark is easily accumulated at the feed inlet of the crushing device 1, the present invention sets the feed inlet position to be conveyed through the collecting part 3. Considering that the bark is light in material and has an arc-shaped structure, a plurality of groups of conveying components 33 are provided on the conveyor belt 31 to increase the friction and thrust of the conveying. Specifically, it relies on the structural characteristics of the conveying components 33 themselves. Because a plurality of conveying components 33 are provided on the conveyor belt 31, there will be gaps between the plurality of conveying components 33, which will provide a greater friction for the bark. Friction, followed by a number of notches arranged on the conveying assembly 33. Considering that the bark is an arc-shaped structure, it is easy to get stuck in the notches in the tangential direction of the bark or on both sides of the bark, so it can provide a certain thrust for the transmission of the bark; secondly, the present invention continues to rely on the feeding assembly 4 arranged just above the conveyor belt 31 to achieve a strong thrust on the bark, so that it can smoothly enter the feed port, and the hanging rod 46 in the feeding assembly 4 can both play a thrust role on the bark, and because it can cooperate with the notch, when the hanging rod 46 moves along the conveying direction When the hanging rod 46 reaches the vicinity of the feed port, it will be lifted up by the lifting assembly 42. At this time, the conveyor belt 31 will continue to be lifted up by inertia. When the hanging rod 46 returns to the initial position of the conveyor belt 31, that is, the end of the conveyor belt 31 away from the feed port, it can continue to provide the conveying power for the conveyor belt 31 and push the bark newly placed on the conveying assembly 33 during the lifting of the hanging rod 46. That is to say, the hanging rod 46 can continue to be lifted up during the lifting of the conveyor belt 31. When adding materials to the conveying assembly 33, the hanging rod 46 can push the bark added during this period when it falls. Even when the hanging rod 46 is located in the groove, that is, when the hanging rod 46 is pushing the bark on the conveying assembly 33, since the scraper 43 and the hanging rod 46 are constantly moving toward the feed port position, material can continue to be added at this time, and then the bark can be conveyed to the crushing device 1 for feeding by relying on the above-mentioned conveying assembly 33. In this way, the problem that the feed port position of the crushing device 1 is easily blocked is solved, and coordinated power is provided for the transmission of the conveyor belt 31.

[0025] It should be noted that two baffles 32 are symmetrically fixed on the support 2 on both sides of the conveyor belt 31 to block the bark and prevent the bark from falling during the conveying process and the advancement of the hanging rod 46; Figure 2As shown, several groups of conveying components 33 are arranged to fit together along the conveying direction of the conveyor belt 31, that is, every two adjacent conveying components 33 are in contact with each other. This is for the purpose of ensuring the continuous and stable conveying of the bark and preventing the bark from being stuck between two conveying components 33. Secondly, the hanging rod 46 cooperates with the notch on the conveying component 33 to facilitate the thrust on the conveying component 33 and prevent it from being stuck between two conveying components 33 without being inserted into the notch. Of course, this will not cause too much impact, as long as the conveying component 33 can be pushed forward and the bark on the conveying component 33 can be pushed forward at the same time. However, as mentioned above, it is also necessary to ensure the stability of the bark conveying and the safety of the equipment. Therefore, the present invention adopts the method of fitting every two adjacent conveying components 33 together.

[0026] The specific structure of the present invention is disclosed below. Figure 2-Figure 3 As shown, the conveying assembly 33 includes a mounting cylinder 331, which is fixedly connected to the conveyor belt 31, a mounting rod 332 is fixedly connected inside the mounting cylinder 331, a conveying plate 333 is rotatably connected to the mounting rod 332, the bottom end of the conveying plate 333 is in contact with the conveyor belt 31, a torsion spring 334 is provided at the connection between the conveying plate 333 and the mounting rod 332, the torsion spring 334 always has a tendency to make the conveying plate 333 in contact with the conveyor belt 31, and a plurality of card slots 335 corresponding to the hanging rods 46 are provided on the conveying plate 333; It is worth mentioning that the side of the conveying plate 333 away from the feed inlet is a smooth structure, and a plurality of second barbs 336 are fixedly connected on both sides of the slot 335. The second barbs 336 are flush with the slot 335, and the hook angle direction of the second barbs 336 faces the feed inlet. Figure 3 , Figure 7 and Figure 8 It can also be seen that the conveying plate 333 is rotatably connected to the mounting rod 332 on one side, and the side rotatably connected to the mounting rod 332 is the side away from the feed port. This design is convenient for the entire conveying assembly 33 to circulate on the conveyor belt 31, and secondly, it is convenient for the coordination between the card slot 335 and the hanging rod 46, because the conveyor belt 31 relies on the hanging rod 46 to be inserted into the card slot 335 to drive the conveying assembly 33 to move, so that the conveyor belt 31 can be transported. Therefore, the conveying plate 333 needs to be rotatably connected to the mounting rod 332 on the side away from the feed port. In this way, it can be ensured that when the hanging rod 46 drives the conveying plate 333 to move, the conveying plate 333 will not tilt on one side, resulting in unstable transmission.

[0027] Secondly, see Figure 1 and Figure 4-Figure 5As shown, the lifting assembly 42 includes a mounting frame 421, a servo motor 422 is fixedly arranged at the bottom of the mounting frame 421, a second reciprocating screw rod 423 is rotatably connected in the mounting frame 421, a second connecting plate 425 is threadedly connected to the second reciprocating screw rod 423, the second connecting plate 425 is fixedly connected to one side of the mounting plate 41, an output end of the servo motor 422 is fixedly connected to the second reciprocating screw rod 423, second limiting rods 424 are fixedly arranged at both sides of the second reciprocating screw rod 423 in the mounting frame 421, and the second connecting plate 425 is slidably connected to the second limiting rod 424; Furthermore, the mounting plate 41 is fixedly provided with first connecting plates 47 at both ends along the conveying direction of the conveyor belt 31, the first reciprocating screw rod 44 is rotatably connected between the first connecting plates 47, first limiting rods 45 are fixedly provided between the first connecting plates 47 and located on both sides of the first reciprocating screw rod 44, the scraper 43 is threadedly connected to the first reciprocating screw rod 44, and the scraper 43 is slidably connected to the first reciprocating screw rod 44, the driving motor 48 is fixedly connected to the first connecting plate 47 away from the feed port, and the output end of the driving motor 48 is fixedly connected to the first reciprocating screw rod 44; For further information, see Figure 6 As shown, a plurality of first barbs 49 are fixedly connected to both sides of the hanging rod 46, and the hook angle direction of the first barb 49 faces the conveying direction of the conveyor belt 31. Here, the hook angles of the first barb 49 and the second barb 336, that is, the direction of their hook tips are all toward the direction of the feed port, so that when pushing the bark, the hook angles of the first barb 49 and the second barb 336 can play an auxiliary role in pushing the bark. First, the hook angle of the first barb 49 can hook the bark between the hanging rods 46 and the bark in contact with the hanging rod 46, making the pushing more convenient. As for the bark that is not in contact with the hanging rod 46, it can be pushed through the bark with the help of the first barb 49; secondly, the slot 335 and the second barb 336 therein Due to the arc-shaped structure of the bark and the bark debris, the slot 335 can easily engage with the arc-shaped structure of the bark, and then the bark can be pushed with the help of the second hook 336 and the corners of the slot 335 away from the feed port to increase the friction. As for the debris, it is easier to be transmitted through the slot 335 and the second hook 336. In addition, the depth of the slot 335 is not deep, and it only serves as a structure to cooperate with the hanging rod 46 to push the conveying plate 333 and increase the friction of the bark, so it will not store a large amount of debris. It should be noted that the distance between the second hooks 336 on both sides of the slot 335 is greater than the distance between the first hooks 49 on both sides of the hanging rod 46, which makes it easier for the hanging rod 46 to be inserted into the slot 335 and push the conveying plate 333.

[0028] It is worth mentioning that the time required for the scraper 43 to move from one end to the other end along the first reciprocating screw rod 44 is adapted to the time required for the second connecting plate 425 to reciprocate along the second reciprocating screw rod 423 for one cycle, and when the second connecting plate 425 moves to the bottom end of the second reciprocating screw rod 423, the bottom end of the hanging rod 46 is located in the slot 335; that is, when the hanging rod 46 is inserted into the slot 335 on a group of conveyor plates 333 from the end of the conveyor belt 31 away from the feed port, the scraper 43 starts to slide on the first reciprocating screw rod 44 with the hanging rod 46 until it reaches the end of the first reciprocating screw rod 44. During this period, the second connecting plate 425 is always at the bottom end of the second reciprocating screw rod 423. When the scraper 43 reaches the end of the first reciprocating screw rod 44 near the feed port, the second connecting plate 42 5 starts to slide upward on the second reciprocating screw rod 423 under the drive of the servo motor 422, driving the entire mounting plate 41 to rise, that is, driving the scraper 43 to rise, so that the hanging rod 46 is separated from the slot 335, and then the conveyor belt 31 continues to operate under the action of inertia, and then the scraper 43 is quickly returned to reset during the process of rising, and the time required for the scraper 43 to reset from the end near the feed port to the initial end is the same as the time required for the second connecting plate 425 to rise from the bottom end to the top end and then to fall to the bottom end, so that it can be ensured that when the scraper 43 is reset to the initial end, the hanging rod 46 can be lowered into the slot 335 again. Even if it is not so coincidental, it is introduced above that the side of the conveyor plate 333 away from the feed port is a smooth structure, so the hanging rod 46 can slide smoothly into the slot 335.

[0029] It should be added that the present invention adopts the reciprocating structure of the lifting component 42 to realize the lifting and lowering of the mounting plate 41 and the reciprocating motion of the scraper 43 because the reciprocating motion of the lifting component 42 is to realize a fixed reciprocating motion time mechanically, and this time is designed to be the same as the time of a stroke of the scraper 43. The mechanical reciprocating motion time is more stable and reliable. If a method such as a hydraulic rod is adopted, the system will need to be frequently adjusted due to the hydraulic pressure and the need for control of the control system, and even hydraulic oil leakage will affect the timing of the coordination between the hanging rod 46 and the second connecting plate 425.

[0030] To sum up, the reciprocating motion structure of the scraper 43 drives the transmission of the conveying component 33, and at the same time, the hanging rod 46 cooperates with the slot 335 to push the bark on the conveying component 33 to prevent the feed port from being blocked. Then, relying on the structure of the slot 335 and the structure of the hanging rod 46, the transmission component 33 is driven to transmit, and the bark is pushed into the feed port together. This effectively solves the problem of the existing bark crusher being easily accumulated at the feed port due to the special structure of the bark and the light material, resulting in blockage of the crusher feed port.
