Description

Technical Field

[0001] The utility model relates to the field of agricultural equipment, and more specifically, to a processing device for recycling crop straw. Background Art

[0002] As a major agricultural country, my country can generate more than 700 million tons of straw every year. Due to the pressure of rural environmental protection, it is no longer allowed to burn the remaining crop straw directly in the field after the crops are harvested. Therefore, it is necessary to improve the comprehensive development and utilization of crop straw and its utilization rate. Against the above background, straw briquetting has become one of the methods for recycling crop straw. The so-called straw briquetting mainly uses biomass compression equipment to process chopped corn stalks, peanut vines, wheat straw and other agricultural and forestry products into small rectangular blocks, which are easy to store and transport, reducing the cost of storage and transportation. If used as fuel, it can also greatly improve the thermal efficiency of biomass.

[0003] At present, when crop straw is recycled through straw briquetting, the straw is cut or crushed in advance, and then the cut or crushed straw is briquetting. Manual cutting is not only inefficient but also has the risk of injury. After the cutting or crushing equipment is used, the processed straw needs to be transported to the straw briquetting equipment for processing. The whole processing process is time-consuming and will also affect the efficiency of crop straw recycling through straw briquetting. Utility Model Content

[0034] Figure 1-Figure 2 A processing device for crop straw recycling provided in an embodiment of the utility model comprises:

[0035] Two collecting boxes 1, both upper and lower ends of which are open;

[0036] A workbench 2, the collection box 1 can be slidably arranged on the upper end thereof, two notches 3 matching the opening at the lower end of the collection box 1 are arranged at intervals on the upper end of the workbench 2, matching bottom plates 4 are arranged horizontally at the notches 3, and the bottom plates 4 are drivingly connected to the jacking mechanism arranged below the workbench 2;

[0037] A crushing mechanism 5, which is arranged on the workbench 2 and located between the two notches 3;

[0038] Two pressing mechanisms 6, which are respectively arranged above the two bottom plates 4;

[0039] A driving mechanism, which is respectively connected to the two collecting boxes 1 to drive the two collecting boxes 1 to move to below the crushing mechanism 5 and one of the briquetting mechanisms 6;

[0040] The conveying mechanism 7 is arranged below the workbench 2 .

[0041] In this embodiment, in the initial state, the lifting mechanism drives the corresponding bottom plate 4 to move upward to seal the gap 3, and at this time, both gaps 3 are sealed. One of the collecting boxes 1 is located below the crushing mechanism 5, and the other collecting box 1 is located below the briquetting mechanism 6 on the same side. Then, the crushing mechanism 5 crushes the straw, and starts discharging the crushed straw into the collecting box 1 below it. After the collecting box 1 is full of straw, the crushing mechanism 5 stops discharging, and the driving mechanism drives the two collecting boxes 1 to move, so that the other empty collecting box 1 moves to the bottom of the crushing mechanism 5, and the crushing mechanism 5 starts discharging again. At the same time, the collecting box 1 full of straw is moved to the bottom of the briquetting mechanism 6 on the same side. At this time, the lower end opening of the collecting box 1 is sealed by the gap 3, and the briquetting mechanism 6 above can start working to briquette the straw in the collecting box 1 below it. By analogy, the crushing mechanism 5 discharges materials periodically, and the two collecting boxes 1 of the driving mechanism move, so that there is always an empty collecting box 1 under the crushing mechanism 5 to collect the straw discharged by the crushing mechanism 5, and at the same time, another collecting box 1 full of straw is briquetting at the corresponding briquetting mechanism 6. After the briquetting is completed, the jacking mechanism drives the corresponding bottom plate 4 to move downward to open the gap 3. At this time, the compressed straw blocks in the collecting box 1 can fall from the gap 3, move with the jacking mechanism, and then be moved to the conveying mechanism 7 by the jacking mechanism, and the compressed straw blocks are sent to the packaging place by the conveying mechanism 7. The conveying mechanism 7 can use the existing belt conveyor.

[0042] In this embodiment, the crushing mechanism 5 and the briquetting mechanism 6 can be made of existing technology, which will not be described in detail here. Figure 1 As shown in , the lower pressing plate is driven by the hydraulic cylinder to move up and down, and the lower pressing plate is moved downward to briquette the straw in the collecting box 1.

[0043] Preferably, as another embodiment of the utility model, the driving mechanism includes:

[0044] A slide rail 8, which is horizontally arranged on the workbench 2;

[0045] A slide plate 9 is slidably disposed on the slide rail 8, and the two collecting boxes 1 are disposed on the slide plate 9 and penetrate the slide plate 9;

[0046] A driving unit is arranged on the workbench 2 and is transmission-connected to the slide plate 9 .

[0047] In this embodiment, the slide plate 9 moves on the slide rail 8, and the slide rail 8 defines the movement trajectory of the slide plate 9, and the slide rail 8 is driven to slide by the driving unit. As one specific implementation method, the driving unit includes: two connecting plates 10, which are respectively arranged at the middle of both ends of the slide plate 9; two first hydraulic cylinders 11, which are respectively arranged on both sides of the slide plate 9, and the cylinder body of the first hydraulic cylinder 11 is connected to the workbench 2, and its telescopic rod is horizontally arranged and connected to the connecting plate 10 on the same side. The two first hydraulic cylinders 11 work synchronously, and the slide plate 9 is driven to move by the extension and retraction of their telescopic rods, so that one of the two collection boxes 1 is moved to the bottom of the crushing mechanism 5.

[0048] Preferably, as another embodiment of the present invention, limit blocks are respectively provided at both ends of the slide rail 8 .

[0049] In this embodiment, by providing limiting blocks at both ends of the slide rail 8, the slide plate 9 is limited by the limiting pieces when the slide plate 9 moves to two extreme positions.

[0050] Preferably, as another embodiment of the present utility model, Figure 3 As shown, the lifting mechanism comprises:

[0051] A second hydraulic cylinder 12, whose telescopic rod is vertically arranged and connected to a connecting seat 13, and the bottom plate 4 is rotatably connected to the connecting seat 13;

[0052] The two ends of the electric push rod 14 are rotatably connected to the connecting seat 13 and the lower end of the bottom plate 4 respectively.

[0053] In this embodiment, the electric push rod 14 is extended and retracted to drive the bottom plate 4 to rotate relative to the connecting seat 13, so that the bottom plate 4 can be horizontal or inclined. Figure 3As shown, when the electric push rod 14 is extended to its longest state and the bottom plate 4 is horizontal, the second hydraulic cylinder 12 drives the bottom plate 4 to move upward to seal the gap 3. After the second hydraulic cylinder 12 drives the bottom plate 4 to move downward to open the gap 3, the pressed straw block will also drop to the bottom of the workbench 2. At this time, the electric push rod 14 shrinks to its shortest state, and the bottom plate 4 will also rotate and tilt accordingly, so that the pressed straw block on the upper end of the bottom plate 4 will slide downward and fall onto the conveying mechanism 7.

[0054] Preferably, as another embodiment of the utility model, it also includes:

[0055] The two limit boxes 15 are opened at both upper and lower ends, and are respectively arranged under the two notches 3 and connected to the workbench 2 .

[0056] In this embodiment, by providing the limit box 15, the bottom plate 4 can enter the limit box 15 only when it is horizontal, and the limit box 15 limits the bottom plate 4 so that it remains horizontal.

[0057] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
