Description

Technical Field

[0001] This invention relates to the field of agricultural waste treatment equipment technology, specifically to a straw recycling briquetting device. Background Technology

[0002] With the development of agricultural modernization, my country produces a large amount of crop straw every year. As an important renewable resource, straw has high utilization value and can be used in the fields of fuel, feed, and organic fertilizer raw materials. However, straw itself has the characteristics of large volume, low density, and inconvenience in transportation and storage, which limits its large-scale utilization. Therefore, compressing straw into briquettes to reduce volume and increase density has become a key link in realizing the resource utilization of straw.

[0003] Existing straw briquetting devices have several shortcomings in practical applications: First, the lack of a sealing mechanism at the feed inlet of the box makes it easy for straw to overflow during the compression process, preventing complete compression and resulting in material waste and increased equipment cleaning difficulty. Although some devices have sealing structures, they are mostly fixed and non-adjustable, unable to adapt to different straw processing needs. Second, current discharge control mostly relies on manual operation or simple baffle structures, which cannot achieve precise and continuous discharge adjustment, easily leading to material blockage or leakage, affecting the continuous operation efficiency of the device. These defects and shortcomings necessitate improvements. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a straw recycling briquetting device. By setting a sealing mechanism at the feed inlet of the box, after the straw feeding is completed, the sealing mechanism is driven to move the sealing plate in the sealing mechanism and cover the feed inlet of the box. This prevents the straw from overflowing from the feed inlet during compression, ensuring the compression effect of the straw and solving the problem of imperfect straw compression effect in current devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] A straw recycling briquetting device includes a box body and a feeding hopper connected to the feeding inlet of the box body. The box body has a hollowed-out groove below the feeding inlet, and sliding grooves are provided on both sides of the hollowed-out groove. A sealing mechanism is provided at the hollowed-out groove and sliding groove of the box body. The sealing mechanism can slide along the sliding groove and cover the feeding inlet, thereby preventing the straw from overflowing from the feeding inlet of the box body when it is compressed. The sealing mechanism includes a sealing plate and sliders fixedly connected to both sides of the sealing plate. The sliders are slidably connected to the corresponding sliding grooves opened in the box body. The sealing mechanism also includes a pneumatic push rod installed on the box body. The end of the output shaft of the pneumatic push rod is fixedly connected to a traction frame, and a traction rod is fixedly connected to one side of the sealing plate. The end of the traction rod extends through a hole in the box body to the outside of the box body and is connected and fixed to the traction frame.

[0009] Furthermore, both sides of the box are provided with pressing mechanisms. The pressing mechanism includes a hydraulic cylinder installed on the side wall of the box and a pressing plate fixedly connected to the end of the output shaft of the hydraulic cylinder for pressing the straw. Two limiting rods are symmetrically fixedly connected to one side of the pressing plate. Limiting holes adapted to the limiting rods are opened on the side wall of the box. The limiting rods pass through and slide in the corresponding limiting holes.

[0010] Furthermore, a drainage hole is provided on the lower part of the side wall of the box, and a water collection box is fixedly connected to the outside of the box at the position corresponding to the drainage hole. The drainage hole is connected to the inside of the water collection box, and a drainage pipe is connected to one side of the water collection box.

[0011] Furthermore, the bottom of the box is provided with two symmetrically distributed discharge control mechanisms. The discharge control mechanism includes two supports symmetrically fixed to the lower surface of the box, and a rotating rod rotatably connected between the two supports. A baffle plate is fixedly connected to the rotating rod. When the rotating rod rotates, the rotation angle of the baffle plate can be adjusted, thereby realizing the discharge control of the squeezed straw.

[0012] Furthermore, the discharge control mechanism also includes a C-shaped plate and two guide rails symmetrically fixed to the side wall of the box. A sliding block is fixedly connected to one side of the C-shaped plate and is slidably connected to the corresponding guide rail. A rack is fixedly connected to the lower surface of the C-shaped plate, and a gear is coaxially fixed to the end of the rotating rod, with the gear meshing with the rack.

[0013] Furthermore, an electric push rod is installed on one side of the housing, and a connecting plate is fixedly connected between one side of the C-shaped plate and the end of the output shaft of the electric push rod.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a briquetting device for straw recycling, which has the following beneficial effects:

[0016] 1. This invention provides a sealing mechanism at the feed inlet of the container. The sealing mechanism includes a sealing plate, a traction rod, a traction frame, and a pneumatic push rod. The sealing mechanism, driven by the pneumatic push rod, can automatically control the sealing plate to slide along the chute, accurately covering the channel below the feed inlet and effectively preventing straw from being squeezed out. The cooperation between the slider and the chute ensures that the sealing plate moves smoothly without deviation, adapting to different straw processing needs with different feed amounts. No manual intervention is required, reducing the difficulty of operation.

[0017] 2. The present invention uses an electric push rod driven discharge control mechanism, which uses rack and pinion to drive the baffle plate to rotate, and can precisely adjust the discharge port gap to achieve quantitative and continuous discharge of the compressed blocks, effectively avoiding material blockage or leakage. The cooperation between the guide rail and the sliding block ensures that the C-shaped plate moves smoothly, further improving the discharge control accuracy and ensuring the continuous operation efficiency of the device.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in one embodiment of the present invention, a straw recycling briquetting device includes a box body 1 and a feeding hopper 9 connected to the feeding inlet of the box body 1. A perforated groove 7 is provided below the feeding inlet of the box body 1, and sliding grooves 8 are provided on both sides of the perforated groove 7. A sealing mechanism 2 is provided at the perforated groove 7 and sliding grooves 8 of the box body 1. The sealing mechanism 2 can slide along the sliding grooves 8 and cover the feeding inlet, thereby preventing straw from overflowing from the feeding inlet of the box body 1 during compression. The sealing mechanism 2 includes... The sealing plate 201 and the sliders 202 fixedly connected to both sides of the sealing plate 201 are slidably connected to the corresponding grooves 8 opened in the housing 1. The sealing mechanism 2 also includes a pneumatic push rod 205 installed on the housing 1. The end of the output shaft of the pneumatic push rod 205 is fixedly connected to a traction frame 204, and a traction rod 203 is fixedly connected to one side of the sealing plate 201. The end of the traction rod 203 extends through the hole on the housing 1 to the outside of the housing 1 and is connected and fixed to the traction frame 204.

[0028] It should be noted that the feeding hopper 9 is designed to facilitate the feeding of straw. In use, the straw to be processed is first introduced into the box 1 through the feeding hopper 9, which is connected to the feeding port of the box 1. In the initial state, the pneumatic push rod 205 of the sealing mechanism 2 is in a retracted state. The traction frame 204 at the end of the output shaft pulls the traction rod 203 on one side of the sealing plate 201, so that the sealing plate 201 moves outward with the sliding cooperation of the sliders 202 on both sides and the slide groove 8 of the box 1, opening the channel below the feeding port to ensure that the straw is introduced smoothly. When the amount of straw introduced meets the straw compression requirements, the pneumatic push rod 205 extends, pushing the traction frame 204 and the traction rod 203 to drive the sealing plate 201 to slide inward along the slide groove 8 until the sealing plate 201 covers the feeding port, preventing the straw from overflowing from the feeding port during the subsequent compression process and providing a closed environment for the briquetting process.

[0029] like Figure 1 and Figure 4As shown, in some embodiments, a pressing mechanism 3 is provided on both sides of the box body 1. The pressing mechanism 3 includes a hydraulic cylinder 301 installed on the side wall of the box body 1, and a pressing plate 303 fixedly connected to the end of the output shaft of the hydraulic cylinder 301 for pressing the straw. Two limiting rods 302 are symmetrically fixedly connected to one side of the pressing plate 303. A limiting hole adapted to the limiting rod 302 is opened on the side wall of the box body 1. The limiting rod 302 passes through and slides in the corresponding limiting hole.

[0030] It should be noted that after the sealing mechanism 2 completes the sealing of the feed inlet, the pressing mechanism 3 is activated. The output shaft of the hydraulic cylinder 301 installed on the side wall of the box 1 extends, pushing the pressing plate 303 fixed at the end to move towards the middle of the box 1, applying extrusion pressure to the straw inside, and extruding and molding the straw. At the same time, the two limiting rods 302 symmetrically fixed on one side of the pressing plate 303 slide along the matching limiting holes on the side wall of the box 1, providing stable guidance for the pressing plate 303, preventing the pressing plate 303 from shifting during the extrusion process, ensuring that the straw is subjected to uniform force, and thus forming straw blocks with consistent density and qualified molding quality.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, a drain hole 6 is provided on the lower part of the side wall of the box 1, and a water collection box 5 is fixedly connected to the outside of the box 1 at the position corresponding to the drain hole 6. The drain hole 6 communicates with the inside of the water collection box 5, and a drain pipe is connected to one side of the water collection box 5.

[0032] It should be noted that during the pressing process of the briquetting mechanism 3, the water contained in the straw condenses into liquid under the pressure of the pressing force, flows down the inner wall of the box 1, and finally flows into the water collection box 5 fixed at the corresponding position on the outside of the box 1 through the drainage hole 6 opened at the lower part of the side wall of the box 1; the drainage pipe connected to one side of the water collection box 5 can drain the water, thereby improving the storage stability of the briquetting.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the bottom of the box 1 is provided with two symmetrically distributed discharge control mechanisms 4. The discharge control mechanism 4 includes two supports 405 symmetrically fixed to the lower surface of the box 1, and a rotating rod 406 rotatably connected between the two supports 405. A baffle plate 404 is fixedly connected to the rotating rod 406. When the rotating rod 406 rotates, the rotation angle of the baffle plate 404 can be adjusted, thereby realizing the discharge control of the squeezed straw.

[0034] It should be noted that when the straw briquettes are formed and the discharge operation is required, an external force drives the rotating rod 406 to rotate around two supports 405 symmetrically fixed on the lower surface of the box 1. During the rotation of the rotating rod 406, the baffle plate 404 fixed on it rotates synchronously. By adjusting the rotation angle of the baffle plate 404, the gap between the baffle plate 404 and the discharge port at the bottom of the box 1 is changed, thereby controlling the discharge speed and flow rate of the formed briquettes, realizing the orderly discharge of the compressed straw briquettes, and avoiding material blockage or leakage.

[0035] like Figure 5 and Figure 6 As shown, in some embodiments, the discharge control mechanism 4 further includes a C-shaped plate 401 and two guide rails 4010 symmetrically fixed to the side wall of the housing 1. A sliding block 409 is fixedly connected to one side of the C-shaped plate 401, and the sliding block 409 is slidably connected to the corresponding guide rail 4010. A rack 408 is fixedly connected to the lower surface of the C-shaped plate 401, and a gear 407 is coaxially fixed to the end of the rotating rod 406. The gear 407 meshes with the rack 408.

[0036] It should be noted that when the rotating rod 406 needs to be driven to rotate, an external force is applied to the inverted plate 401, causing the inverted plate 401 to slide smoothly along the guide rail 4010 symmetrically fixed to the side wall of the box 1 via the sliding block 409 fixed on one side. During the sliding process of the inverted plate 401, the rack 408 fixed on its lower surface moves synchronously. The rack 408 meshes with the gear 407 coaxially fixed at the end of the rotating rod 406, converting the linear motion of the inverted plate 401 into the rotational motion of the gear 407, which in turn drives the rotating rod 406 to rotate, providing stable power transmission for the angle adjustment of the baffle plate 404 and ensuring the accuracy of the discharge control.

[0037] like Figure 5 As shown, in some embodiments, an electric push rod 402 is installed on one side of the housing 1, and a connecting plate 403 is fixedly connected between one side of the C-shaped plate 401 and the end of the output shaft of the electric push rod 402.

[0038] It should be noted that when it is necessary to drive the C-shaped plate 401 to slide, the electric push rod 402 installed on one side of the box 1 is activated. The output shaft of the electric push rod 402 extends and retracts according to the control command. Through the connecting plate 403 fixedly connected to one side of the C-shaped plate 401 at the end of the output shaft, the power of the electric push rod 402 is transmitted to the C-shaped plate 401, which drives the C-shaped plate 401 to slide along the guide rail 4010. There is no need to manually push the C-shaped plate 401, realizing the automated operation of the discharge control mechanism 4 and improving the overall automation level and operating efficiency of the device.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
