Embodiment 1

[0032] like figure 1 as shown, figure 1 It is a schematic diagram of the overall structure, which is moved by a traction mechanism. The front end has a straw picking and processing device 50 for picking up and crushing straw. The frame is also equipped with a straw storage room 60 and a straw conveying device. The conveying device in the prior art conveys to the straw storage room, and the straw conveying device sends the straw to the molding device. Among them, the straw storage room can be equipped with a dust removal device according to actual needs to remove the dust. It is worth noting that this part of the content is all existing technology, and its principle adopts the straw picking and pulverizing machine on the market.

[0033] like figure 2As shown, a traction-type straw biomass granulator provided by the embodiment of the present invention has a shell, and the shell has a feed port, and the feed port corresponds to the output of the above-mentioned crushing devi...

Embodiment 2

[0041] Due to the limited pre-extrusion of the material and the limited delivery volume of the material by the offset of the sliding tooth 11, for loose straw, it can be squeezed in advance to form a dense structure, which can effectively increase the effective actual delivery volume of a single time, so in the implementation On the basis of Example 1, this embodiment also includes a preloading device 40 and a second driving device, such as figure 2 and Figure 4 As shown, the preloading device 40 includes a base wheel 41 and several preloading rods 42, the number of the preloading rods 42 is greater than the number of the drive teeth 21, and several preloading rods 42 are evenly distributed on the peripheral side of the base wheel 41 in the circumferential direction. The rod 42 is rotatably mounted on the base wheel 41 through a torsion spring. Specifically, the preload rod 42 has a plate-like structure, and its two ends are respectively rotatably mounted on the base wheel 4...

Embodiment 3

[0045] When the green straw is recycled, the water content in the straw is relatively high, and the straw will generate a lot of heat due to the gear meshing and the rapid impact and friction of the pre-compression rod 42, which will evaporate the water, and more water vapor will cause intermolecular The distance increases, which affects the conduction of heat and reduces the cohesive force of the straw. Due to the limited internal space of the granulator, the water vapor cannot be discharged in time, and the evaporated water vapor forms a high pressure, which leads to volume expansion, increases the space it occupies, and "steam blockage" occurs. The ejection in the forming hole 22 produces the phenomenon of "blasting".

[0046] Therefore, on the basis of the second embodiment, the present embodiment also includes a vacuum pump, such as Figure 4 As shown, the base wheel 41 is provided with a dehumidification hole 43 with an open end, and the vacuum pump penetrates into the ...

Abstract

The invention discloses a pull-type straw biomass particle making machine, and belongs to the field of agricultural machinery. The device comprises a first driving device and a forming device, wherein the forming device comprises a driving gear and a forming gear; involute driving teeth are evenly distributed on the driving gear in the circumferential direction, a storage groove is formed between every two adjacent driving teeth, an output hole is formed in the driving gear in the axial direction, and an auger is arranged in the output hole. A forming hole is formed in the position, between every two adjacent driving teeth, of the driving gear, and the forming holes penetrate into the output hole and the storage groove; the forming gear comprises a base body, a plurality of involute sliding teeth and a plurality of reset springs. The sliding teeth are evenly distributed on the circumferential side of the base body in the circumferential direction. A plurality of sliding grooves are formed in the positions, in one-to-one correspondence with the sliding teeth, of the base body, and sliding blocks are integrally formed on the sliding teeth. According to the invention, fed materials can be subjected to one-time volume compression, so that the actual quantity of the fed materials at a time is increased, the production efficiency is effectively improved, the miniaturization design of gears is facilitated, and the requirement on equipment power is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a traction-type straw biomass pellet making machine. Background technique [0002] With the popularization of agricultural production mechanization, agricultural planting has mostly realized mechanized operation. With the improvement of environmental protection awareness, the burning of straw after planting crops has also begun to be banned and recycled. The stalks after crop harvest can be used as fuel, fertilizer or animal feed, and have high utilization value. [0003] Straw picking and granulation directly is a straw processing method with higher income in the prior art. After the separated straw is crushed by a combine harvester or special harvesting machinery, the straw can be made into granules by double-roller granulation, so that it can be used for fuel, fertilizer and feed after subsequent processing. By mixing other additives into the straw, the granulated stra...
