Description

Technical Field

[0001] The present invention relates to the technical field of wood chip storage, and particularly relates to a wood chip bin for preventing material accumulation during feeding. Background Art

[0002] Wood chips are one of the main raw materials for producing pallets. After mixing the wood chip raw materials with glue, they are molded under high temperature conditions by a hydraulic press to finally produce wood chip pallets. The wood chip bin used in pallet production is mainly used for storing and managing wood chip raw materials. The wood chip bin provides a dedicated space to store a large amount of wood chips, ensuring the continuity and stability during the production process, which is crucial for ensuring the normal operation of the production line. Usually, the bin has a large volume, and a feeding method with an opening design on the side or one side of the bottom of the bin is adopted for feeding. Since a large amount of wood chips placed in the bin will exert pressure on the wood chips at the bottom, if only one side is used for discharging, the wood chips will not be discharged smoothly. At the same time, when the wood chips are placed in the bin for a long time, the wood chips will accumulate together, and arching will occur during discharging, resulting in the problem of unsmooth discharging. Therefore, the present invention provides a wood chip bin for preventing material accumulation during feeding. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a wood chip bin for preventing material accumulation during feeding to solve the problems of wood chip accumulation and arching during discharging resulting in unsmooth discharging mentioned in the above background art.

The anti-arching mechanism includes a vibrating plate and a plurality of knocking members. The vibrating plate is arranged in a grid pattern in the bin, and the vibration generated by the knocking members can be transmitted to the vibrating plate.

[0005] Further, the knocking member includes a knocking cylinder with a hollow structure. A plurality of knocking blocks are arranged on the inner wall of the knocking cylinder.

Detailed implementation mode

[0015] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0016] As Figures 1-7 As shown, the present invention provides a sawdust silo for preventing material accumulation during discharging, including a support 1 and a silo 2 arranged on the support 1. The silo 2 is of a rectangular structure. One side of the lower part of the silo 2 is provided with a discharge frame 3 communicated with the silo 2. The bottom of the discharge frame 3 is provided with a discharge port 4. A belt conveyor 4 is arranged at the discharge port 4 end of the discharge frame 3. A plurality of first auger conveyors 6 for feeding materials to the discharge port 4 are arranged side by side at the bottom in the silo 2. An anti-arching mechanism 7 is arranged in the silo 2 and above the first auger conveyor 6. The anti-arching mechanism 7 includes a vibrating plate 71 and a plurality of knocking members 72. The vibrating plate 71 is arranged in a grid pattern in the silo 2. The vibration generated by the knocking members 72 can be transmitted to the vibrating plate 71. The grid-shaped vibrating plate 71 can increase the contact area between the anti-arching mechanism 7 and the sawdust in the silo 2 and improve the arch-breaking efficiency.

[0017] As Figures 1-4 As shown, a climbing ladder is installed on one side of the silo 2, which is convenient for observing the situation at the top of the silo 2. The silo 2 is of a rectangular structure, and the first auger conveyors 6 are arranged side by side at the bottom of the silo 2. The first auger conveyors 6 can evenly discharge the sawdust in the silo 2. Compared with the existing funnel-shaped silo, the situation of sawdust accumulation during discharging in the silo 2 can be significantly reduced. At the same time, during the discharging process of the plurality of first auger conveyors 6 arranged side by side, the sawdust above the discharge port will be agitated, and the occurrence of sawdust arching will also be reduced. In this embodiment, the vibration generated by the knocking of the knocking members 72 is transmitted to the vibrating plate 71. The vibrating plate 71 contacts the sawdust. On the one hand, the amplitude of the vibrating plate 71 will loosen the sawdust in the silo 2. The vibrating plate 71 transmits the vibration to the sawdust in the silo 2, breaking the adhesion force between the materials and loosening the materials, thereby reducing the occurrence of arching phenomenon.

[0018] The knocking member 72 includes a knocking cylinder 721 with a hollow structure. A plurality of knocking blocks 722 are fixedly arranged on the inner wall of the knocking cylinder 721. A rotating shaft 723 is arranged inside the knocking cylinder 721. Both ends of the rotating shaft 723 are rotatably connected to the inner wall of the silo 2. A plurality of connecting rods 725 are connected to the rotating shaft 723 through hinge seats 724. The plurality of connecting rods 725 are spirally distributed on the rotating shaft 723. One end of the connecting rod 725 is connected with a knocking head 726.

[0019] As Figure 3 and 5 shown, when the rotating shaft 723 rotates, under the action of centrifugal force, the connecting rod 725 drives the knocking head 726 to strike on the knocking block 722, so that the knocking cylinder 721 vibrates. The amplitude of the knocking cylinder 721 is transmitted to the vibrating plate 71, and the vibration is dispersed at multiple places in the silo 2 through the vibrating plate 71, so as to keep the wood chips in the silo 2 loose.

[0020] The vibrating plate 71 includes two groups, which are respectively arranged above and below the knocking cylinder 721.

[0021] As Figure 3 or shown in Figure 4, the contact area between the vibrating plate 71 and the wood chips can be increased, so as to loosen the wood chips in the silo 2 and prevent the arching phenomenon.

[0022] Both ends of the knocking cylinder 721 are connected to the inner wall of the silo 2 through flange seats 73. A plurality of springs 74 are connected between the inner wall of the knocking cylinder 721 and the flange seats 73.

[0023] As Figures 5-7 shown, the knocking cylinder 721 is indirectly installed in the silo 2 through the flange seat 73. Both ends of the rotating shaft 723 respectively pass through the flange seat 73 and are rotatably connected to the inner wall of the silo 2. By utilizing the elastic force of the spring 74, the knocking cylinder 721 vibrates when being knocked by the knocking member 72, and at the same time, the amplitude of the knocking cylinder 721 is increased, indirectly improving the loosening effect of the wood chips.

[0024] A power assembly 75 is arranged on one side of the silo 2. The power assembly 75 includes a driving motor 751, a driving belt pulley 752 and a driven belt pulley 753. The output end of the driving motor 751 is connected with the driving belt pulley 752. The driven belt pulley 752 is installed on any one of the rotating shafts 723. A first belt 754 is connected between the driving belt pulley 752 and the driven belt pulley 753. The adjacent two rotating shafts 723 are driven by a belt pulley 755 and a second belt 756.

[0025] As Figure 3As shown, the driving motor 751 is a reduction motor. The driving motor 751 is installed on one side of the silo 2 through a support frame. Under the action of the first belt 754, the driving motor 751 drives any one of the rotating shafts 723 to rotate. Under the action of the belt pulley 755 and the second belt 756, several rotating shafts 723 rotate synchronously. When the rotating shaft 723 rotates, it drives the knocking head 726 to knock the knocking block 722, thereby realizing the vibration of the vibrating plate 71.

[0026] On both sides of the belt of the belt conveyor 4, baffles 4 are provided. A number of partitions are evenly provided on the belt of the belt conveyor 4.

[0027] As Figure 1 shown, the function of the baffle is to prevent sawdust from falling when it falls on the belt of the belt conveyor 4. The combination of two adjacent partitions and the baffle 4 forms a frame structure with an upward opening, which can be used to prevent sawdust from sliding on the belt during the process of rising to the feeder, realizing the stable transportation of sawdust.

[0028] At the top of the silo 2, a second auger conveyor 8 is provided. A number of feed inlets 9 are opened at the bottom of the second auger conveyor 8, and a slide valve 10 is provided at the bottom of each feed inlet 9.

[0029] As Figure 1 shown, the second auger conveyor 8 is used to convey the processed sawdust into the silo 2. The multiple feed inlets 9 at the bottom of the second auger conveyor 8 are used to evenly convey the material into the silo 2, and the slide valve 10 is used to control the opening and closing of the feed inlet 9.

[0030] Two sets of rotary vane level gauges 11 are provided in the silo 2.

[0031] As Figure 1 shown, the two rotary vane level gauges 11 are distributed in the upper and lower parts of the silo 2, used for detecting the upper and lower limits of the sawdust in the silo 2 for monitoring and control, to ensure the stable and efficient storage and transportation of the material. The rotary vane level gauge 11 in the upper part of the silo 2 is used to prevent the material from overflowing. When the sawdust in the silo reaches the set upper limit, the upper rotary vane level gauge 11 will send a signal to prompt the operator to stop feeding, thus avoiding the material overflowing from the silo; the main function of the rotary vane level gauge 11 in the lower part is to prevent the material from being short. When the sawdust in the silo drops to the set lower limit, the lower rotary vane level gauge 11 will send a signal to prompt the operator to supplement the material to ensure the continuity and stability of the production process.

[0032] Principle of use: During use, the processed wood chip raw materials are conveyed into the silo 2 through the second auger conveyor 8. The first screw conveyor 6 at the bottom of the silo 2 conveys the wood chips at the bottom of the silo 2 to the discharge port 4, and they fall from the discharge port 5 onto the belt conveyor 4. The belt conveyor 4 conveys them into the feeder. While multiple first auger conveyors 6 arranged side by side can discharge the wood chips above them, they can also stir to promote the flow of the wood chips, thereby reducing the occurrence of material blockage and accumulation. At the same time, the driving motor 751 drives the driving pulley 752 to drive the driven pulley 753 to rotate. The driven pulley 753 drives the rotating shaft 723 to rotate. The rotation of the rotating shaft 723 will drive the connecting rod 723 and the knocking head 726 to rotate. Under the action of centrifugal force, the knocking head 723 knocks the knocking block 722. When the knocking head 726 contacts the knocking block 722, vibration is generated. Under the action of the spring 74, the knocking cylinder 721 vibrates, thereby driving the vibrating plates 71 above and below the knocking cylinder 721 to vibrate. The vibrating plates 71 are distributed in the silo 2 and can loosen the wood chips in the silo 2, thereby preventing the occurrence of arching phenomenon.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
