Description

Technical Field

[0001] This utility model relates to the field of agricultural straw crushing technology, specifically to an agricultural straw crushing and processing equipment. Background Technology

[0002] In agricultural production, straw disposal is an important issue. Traditional straw disposal methods, such as burning, not only cause environmental pollution but also waste a lot of resources. With the increasing awareness of environmental protection and the promotion of the concept of resource recycling, it has become particularly important to effectively crush and rationally utilize straw.

[0003] Currently, some existing straw crushing and processing equipment often have inconsistent crushing degrees during the crushing process, resulting in straw of varying sizes. This causes many inconveniences in subsequent application scenarios. The accumulation of coarse straw leads to an imbalance in soil permeability. In biomass fuel production, uneven straw size can cause instability in combustion speed and heat release, affecting energy conversion efficiency and the normal operation of combustion equipment. Meanwhile, some existing straw crushing equipment uses straw that contains a certain amount of moisture, especially in the early stages after harvesting when the moisture content is relatively high. This causes the straw to stick to the crushing rollers during crushing, which not only causes blockages but also affects the crushing process. In addition, the internal moisture can corrode and rust the crushing rollers when in contact with them, leading to jamming and other issues that also affect the crushing process. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural straw crushing and processing device to solve the problems mentioned in the background art.

[0010] Preferably, an air inlet is provided on one side of the heating box, and a dustproof net is provided on the inner surface of the air inlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a spring, a sieve plate, and a driving mechanism. The driving mechanism can apply and release pressure to the sieve plate and spring. The elasticity of the spring drives the sieve plate to vibrate and sieve, allowing straw of the desired size to be sieved out for use. This enables the straw fragments to be mixed more evenly into the soil, improving soil physical structure and fertility. The straw can also be pulverized to a suitable size for subsequent combustion, improving combustion efficiency.

This allows the straw fragments to be mixed more evenly into the soil to improve the soil physical structure and enhance fertility. The straw can also be crushed to a suitable size for subsequent combustion and improve the combustion effect.

[0017] By setting up the heating mechanism 5, the driving mechanism 3 can discharge the hot air from the heating mechanism 5 into the crushing box 1 to dry the straw, prevent the damp straw from sticking and leaving residue, thereby preventing blockage and affecting the crushing, and preventing moisture from corroding and rusting the crushing roller, thus preventing jamming and meeting the needs of users.

[0018] The driving mechanism 3 includes a dual-shaft motor 301 fixedly connected to the other side of the crushing box 1.

The elasticity of the spring 6 can drive the screen plate 7 to vibrate and screen, which can screen out the straw of the required size for convenient use by the user and meet the user's needs.

[0019] The heating mechanism 5 includes a heating box 501 fixedly connected to the other side of the crushing box 1. A heater 502 is installed at the bottom of the inner cavity of the heating box 501. One side of the heating box 501 is connected to an air supply cylinder 503 through an air inlet pipe. A piston 504 is slidably connected to the inner surface of the air supply cylinder 503. A push rod 505 is fixedly connected to one side of the piston 504. The other side of the push rod 505 is fixedly connected to one side of the slide plate 303. One side of the air supply cylinder 503 is connected to the inner cavity of the crushing box 1 through an air outlet pipe. The heating mechanism 5 heats the material through the heater 502. The dual-shaft motor 301 drives the reciprocating screw 302 to rotate. The reciprocating screw 302 drives the slide plate 303, cam 305 and transmission rod 304 to move left and right. Hot air can be drawn out from the heating box 501 through the air inlet pipe and pushed into the crushing box 1 through the air outlet pipe for heating. This can heat and dry the crushed straw, prevent moisture from clogging and affecting the crushing, and prevent moisture from damaging the crushing mechanism 2.

[0020] The inner surface of the slide plate 303 is slidably connected to a slide rod 4. One side of the slide rod 4 is fixedly connected to the other side of the crushing box 1.

Through the first and second one-way valves, hot air can be absorbed through the air inlet pipe and discharged into the pulverizing box 1 through the air outlet pipe, thus facilitating the drying process.

[0022] An air inlet is provided on one side of the heating chamber 501, and a dustproof net is provided on the inner surface of the air inlet. The air inlet allows for convenient air intake and circulation heating. The dustproof net prevents dust from entering the heating chamber 501 through the air inlet, thereby preventing it from affecting the heating of the heater 502.

[0023] It is worth noting that the technical features proposed in this technical solution, such as the crushing mechanism 2, the dual-shaft motor 301, and the heater 502, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0024] Working principle: First, the heater 502 is turned on for heating. Then, the dual-axis motor 301 is turned on, which drives the reciprocating screw 302 to rotate. The reciprocating screw 302 drives the slide plate 303, cam 305, and transmission rod 304 to move left and right. Hot air can be drawn out from the heating box 501 through the air inlet pipe and pushed into the crushing box 1 through the air outlet pipe for heating. This can heat and dry the crushed straw, preventing the crushed damp straw from sticking and leaving residue, thus preventing blockage and affecting the crushing process. It also prevents moisture from corroding and rusting the crushing rollers, preventing jamming. After drying is completed, the servo motor in the crushing mechanism 2 is turned on to drive the crushing rollers to rotate, which can crush the straw.

[0025] When the crushed straw falls onto the sieve plate 7, the dual-shaft motor 301 drives the transmission rod 304 and cam 305 to rotate, which can apply pressure to the sieve plate 7 and the spring 6 and release the pressure. The elasticity of the spring 6 can drive the sieve plate 7 to vibrate and screen, so that the straw of the required size can be screened out for use. This allows the straw fragments to be mixed into the soil more evenly to improve the soil physical structure and enhance fertility. It can also be crushed to a suitable size for subsequent combustion and improve the combustion effect.
