Description

Technical Field

[0001] This utility model relates to the field of straw processing technology, specifically a straw crushing and drying device. Background Technology

[0002] Straw contains nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. More than half of the photosynthetic products of crops are stored in it. As roughage, straw is high in crude fiber and lignin. During processing, straw needs to be crushed, and the crushed straw particles need to be dried for preservation.

[0003] A corn stalk crushing and drying device, disclosed in CN218772954U, includes a machine body with a feed hopper at the top and a discharge port at the bottom. A pair of crushing rollers are located at the top of the machine body, and a screening mechanism is located inside the machine body below the crushing rollers. A motor is mounted on the rear wall of the machine body, and a turntable is fixedly mounted on the rear wall of the machine body via the motor drive end. A fixing ring is provided on the inner wall of the machine body, fitted around the outside of the turntable. This utility model relates to the field of straw processing technology. This device has a compact structure. The crushing rollers crush the straw, and the screening group allows straw that meets the specifications to fall to the bottom for drying, while straw that does not meet the specifications is directly discharged. The motor drives the turntable to rotate, which in turn causes the rotating rod to rotate the tipping plate, avoiding uneven drying caused by material accumulation and improving the drying effect. This provides convenience for users. However, existing straw crushing and drying devices also have the following disadvantages in use:

[0004] (1) Existing straw crushing and drying equipment lacks a vibration structure. Due to the loose nature of straw itself, the crushed material is easy to accumulate on the surface of the filter screen, which will not only cause blockage of the filter channel, but also significantly reduce the screening efficiency and work efficiency.

[0005] (2) The existing straw crushing and drying device has the filter screen and the machine body as one piece. When facing the straw crushing needs of different particle sizes, it is difficult for users to replace the screen with the corresponding specifications. In addition, the screen is complicated to operate and inconvenient to use due to its non-removable nature when it needs to be cleaned or maintained.

[0026] like Figure 3As shown, guide plates 101 are installed on both sides of the top of the crushing structure 4, and the two guide plates 101 are welded to the housing 1. Guide plates 202 are installed on the front and rear sides of the bottom of the crushing structure 4, and the two guide plates 202 are welded to the housing 1. A discharge port 103 is installed in the middle of the front side of the housing 1. A discharge pipe 104 is welded to the bottom of the housing 1. A solenoid valve is installed on one side of the discharge pipe 104. An air inlet pipe 701 is welded to the side of the two heaters 7, and the two air inlet pipes 701 extend out of the housing 1 through the side of the two heaters 7. Several equidistant air outlet pipes 702 are welded to the side of the two heaters 7. The crushing structure 4 includes a motor 201, a central shaft 402 and a crushing roller 403. The two motors 201 are welded to the housing 1. The output end of 401 passes through the housing 1 and is welded with a central shaft 402. The two central shafts 402 are connected to the bearings of the housing 1. The outer walls of the two central shafts 402 are welded with crushing rollers 403. Each set of oscillation structure 6 includes a motor 601, a crank 602 and an oscillating rod 603. The motor 601 is welded to the housing 1. The output end of the motor 601 is welded with a crank 602. The front bearing of the crank 602 is connected to the oscillating rod 603. The top of the oscillating rod 603 is hinged to a moving frame 503. By setting the oscillation structure 6, the motor 601 drives the crank 602 to rotate. The crank 602 drives the oscillating rod 603 to move up and down. The oscillating rod 603 oscillates the hinged moving frame 503, so that the straw particles accumulated on the filter screen 504 are oscillated and filtered, resulting in a good screening effect.

[0027] like Figure 4 As shown, the filter structure 5 includes a fixed plate 501, a first spring 502, a movable frame 503, a filter screen 504, a fixed base 505, a column 506, a second spring 507, a top plate 508, and a locking rod 509. Several first springs 502 are welded to the top of the two fixed plates 501 respectively. The movable frame 503 is welded to the top of the several first springs 502.

When it is necessary to replace or maintain the filter screen 504, the four top plates 508 of the filter structure 5 can be pulled up in sequence. The spring 2 507 is stretched, the clamp 509 is disengaged from the clamping groove 5041, and the top plate 508 is rotated to one side. At this time, the filter screen 504 can be removed for replacement or maintenance. It is convenient to use.
