Description

Technical Field

[0001] The utility model relates to the technical field of biomass recycling, in particular to a straw granulating device with a collecting mechanism. Background Art

[0002] With the increasing awareness of environmental protection and the rapid development of renewable energy technology, the resource utilization of agricultural waste such as straw has attracted more and more attention. As one of the important means, straw granulation technology can convert straw into high-quality biomass pellet fuel, thereby achieving effective resource utilization and environmental protection. However, during operation, existing straw granulation equipment often lacks an effective straw collection mechanism. Most of them need to cooperate with external freight devices, or even directly spray straw pellets onto the bottom for stacking, so most of them are difficult to collect and store.

[0003] At present, there is an existing high-efficiency straw granulation equipment (such as patent number: CN208213103U), which discloses a high-efficiency straw granulation equipment, including a feeding device, a pressure roller device, a discharging device and a screening device, the pressure roller device includes two relatively rotating pressure rollers, the pressure rollers are provided with a convex structure and a forming hole, the feeding device includes a feeding belt, a support roller and a moving roller, the feeding belt rotates in a ring under the drive of the moving roller, the support roller supports the feeding belt to feed the straw raw material into the pressure roller for wrapping, the straw raw material enters the squeezing area of ​​the pressure roller device from bottom to top, and the bulk material not squeezed into the pressure roller falls on the feeding belt. The advantages of the utility model are: the equipment has a high degree of process integration, and each mechanism is very simple, and one device completes the entire granulation process.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The existing device is not provided with a collecting device. After the granulation is completed, the straw pellets are loaded with a car.

[0006] 2. The existing device uses a discharging device and a feeding belt and other structures to transfer the straw layer by layer for the next operation, which requires multiple sets of transmission structures for conveying the straw, resulting in a complex structure. Utility Model Content

When the cutting plate rotates, it will hit the straw particles and beat them to the direction of the material guide port, and enter the silo through the material guide port. When the device is in operation as a whole, the transmission of the straw in various processing links is completed, which solves the problem that the existing device needs to set up multiple transmission structures to transport the straw to various processing links, which has a complex structure.

[0042] Working principle:

[0043] The first step is to prevent the straw from being placed in the hopper 1 and falling between the two crushing ring teeth 211 under the action of gravity, and then start the first motor 901 to drive the second driving gear 207 to rotate, the second driving gear 207 drives the third driven gear 208, the third driven gear 208 drives the fourth driven gear 209, and finally the third driven gear 208 and the fourth driven gear 209 drive the two second rollers 210 to rotate, and the second roller 210 drives the crushing ring teeth 211 to initially crush the straw horizontally, and then start the second motor 9 to drive the first driving gear 202, the first driving gear 202 drives the first driven gear 203, the first driven gear 203 drives the second driven gear 204, and finally the first driven gear 203 and the second driven gear 204 drive the first roller 205 to rotate, the first roller 205 drives the crushing bar 206 to rotate, and the two crushing bars 2 06 The straw that has been crushed by the crushing ring teeth 211 is crushed longitudinally. At this time, the straw has been basically crushed, but there will still be fibers connecting the broken parts. At this time, the crushed straw is pressed into the granulation and cutting device 3 by the crushing bar 206, and the third motor 302 is started to drive the third roller 304, and the third roller 304 drives the end plate 305 to rotate. The third roller 304 also drives the four cutting plates 306 to rotate, and the end plate 305 drives the six cutting blades 307 to rotate. The straw that falls into the granulation and cutting device 3 is first cut by the rapidly rotating cutting blade 307, and then hit by the square hole opened in the cutting plate 306. Finally, the cutting blade 307 cuts the fiber of the straw, and the cutting plate 306 divides the straw into particles under the extremely fast rotation. When the cutting plate 306 rotates, it will hit the straw particles and beat them to the direction of the guide port 6, and enter the silo 7 through the guide port 6.

[0044] In the second step, the straw particles entering the silo 7 are restricted by the silo 7 and will not fly around. They will eventually enter the storage box 8 under the action of gravity. The function of the baffle plate 702 is to guide the material. After granulation is completed, the lock 701 and the lock buckle 803 are unlocked, and the handle 801 is pulled to drive the storage box 8 to transfer it through the running wheels 802 set at the bottom. The storage box 8 itself has the function of storing straw particles.
