Description
Technical Field
[0001] This utility model relates to the technical field of agricultural machinery, specifically a straw crushing device for agricultural machinery. Background Technology
[0002] With the rapid development of agriculture, grain production has been increasing day by day, and the resulting straw problem has become increasingly serious. If the straw is not properly disposed of after the harvest, it will hinder the sowing of new crops. For example, after wheat harvest, a large amount of straw piled up in the field will affect the mechanized sowing of the next season's crops such as corn. The seeder may get tangled in the straw, resulting in uneven sowing or failure to sow normally. Therefore, straw is now generally collected and crushed for recycling as fuel, etc. Straw crushing devices are generally used in the process of crushing straw.
[0003] Existing straw crushing devices typically involve first feeding straw into the crushing chamber, where internal crushing blades apply shearing force to break down the straw, and then the crushed straw is discharged and collected. However, during discharge, the rapid rotation of the crushing blades exerts a certain force on the straw, causing straw fragments to fly out rapidly from the discharge port, resulting in a large area of scattered straw fragments that are difficult to collect. To address these issues, we provide a straw crushing device for agricultural machinery. Utility Model Content
[0004] 1) Technical problems to be solved
[0005] This utility model proposes a straw crushing device for agricultural machinery, which includes components such as a discharge cylinder and rotating plates. After the crushed straw enters the discharge cylinder, it first impacts the rotating plates to prevent it from flying out directly and causing large-scale scattering. The straw is stored between two rotating plates. A power mechanism can drive four rotating plates to rotate synchronously, thereby conveying the straw inside. When the straw moves to the bottom of the discharge cylinder, it enters the interior of a fixed plate and is discharged by the discharge mechanism. This avoids the straw flying out rapidly over a large area, making it easier to collect. This solves the problem that existing straw fragments fly out rapidly at the discharge port, resulting in a large area of straw fragments splashing and making it difficult to collect.
[0006] (ii) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a straw crushing device for agricultural machinery, comprising a crushing box, a discharge cylinder on one side of the crushing box, and a connecting mechanism between the discharge cylinders of the crushing box; a feeding plate fixedly connected to the upper part of the crushing box, and a crushing assembly inside the crushing box; a power mechanism inside the discharge cylinder, and four rotatable rotating plates outside the power mechanism, dividing the space inside the discharge cylinder into four areas, with the outer surface of the rotating plates slidably connected to the inner wall of the discharge cylinder; a fixing plate fixedly connected to the lower part of the discharge cylinder, and a discharge mechanism inside the fixing plate; and a protective plate fixedly connected to one side of the discharge cylinder.
[0008] Furthermore, the connecting mechanism includes a discharge plate, the upper surface of which is fixedly connected to the crushing box, and a first connecting plate and a second connecting plate are fixedly connected to the outer surface of the discharge cylinder.
[0009] Furthermore, one side of the first connecting plate is detachably connected to the crushing box, and one side of the second connecting plate is detachably connected to the discharge plate.
[0010] Furthermore, the power mechanism includes a first electric motor, which is fixedly mounted on the outer surface of the discharge cylinder. The output shaft of the first electric motor passes through the discharge cylinder and connects to a rotating cylinder, the end of which is rotatably connected to the discharge cylinder.
[0011] Furthermore, the outer surface of the rotating cylinder is fixedly connected to the rotating plate, and the inner wall of the rotating cylinder is provided with multiple filter holes.
[0012] Furthermore, the discharge mechanism includes a second motor, which is fixedly mounted on the outer surface of the fixed plate. A rotating rod is fixedly connected to the output end of the second motor. One end of the rotating rod is rotatably connected to the fixed plate, and the other end of the rotating rod is rotatably connected to the protective plate.
[0013] Furthermore, a helical blade is fixedly connected to the outer surface of the rotating rod, and the outer surface of the helical blade is slidably connected to the fixed plate.
[0014] (iii) Beneficial effects:
[0015] Compared with existing technologies, this straw crushing device for agricultural machinery has the following advantages:
[0016] I. This agricultural machinery straw crushing device, through the setting of components such as a discharge cylinder and rotating plates, allows the crushed straw to enter the discharge cylinder and first impact the rotating plates to prevent it from flying out directly and causing large-scale scattering. The straw is stored between two rotating plates, and the power mechanism can drive four rotating plates to rotate synchronously, thereby conveying the straw inside. When the straw moves to the bottom of the discharge cylinder, it enters the interior of the fixed plate and is discharged by the discharge mechanism, thus avoiding the rapid and large-scale flying of straw and facilitating centralized collection. This solves the problem of existing straw fragments flying out rapidly at the discharge port, resulting in a large area of straw fragments splashing and making it difficult to collect the straw.
[0017] II. This agricultural machinery straw crushing device, through the setting of connecting mechanisms and other components, has a first connecting plate fixed to the crushing box by bolts, and a second connecting plate fixed to the discharge plate by bolts, so as to connect the discharge cylinder and the crushing box together. When the discharge cylinder is not needed, the two can be separated for easy selection. The second motor can drive the rotating rod to rotate. When the rotating rod rotates, it can drive the spiral blade to rotate, thereby conveying the straw inside the fixed plate to the outside for discharge. Attached Figure Description

The pulverizing assembly 10 consists of a motor and internal pulverizing components, which can crush the straw. This is existing technology and will not be described in detail here. The discharge cylinder 2 is cylindrical and hollow inside. When the crushed straw enters the discharge cylinder 2, it first impacts the rotating plate 5 to prevent it from flying out directly and causing a large-scale scattering. The straw is stored between two rotating plates 5. The power mechanism 4 can drive four rotating plates 5 to rotate synchronously, thereby conveying the straw inside. When the straw moves to the bottom of the discharge cylinder 2, it enters the fixed plate 6 and is discharged by the discharge mechanism 7 to facilitate discharge, thereby preventing the straw from flying out quickly and over a large area and making it easier to collect. Support legs 11 are provided at the bottom of both the pulverizing box 1 and the discharge cylinder 2 for support and fixation.
[0027] The connecting mechanism 3 includes a discharge plate 301, the upper surface of which is fixedly connected to the crushing box 1.

When the discharge cylinder 2 is not needed, the two can be separated.
[0028] The power mechanism 4 includes a first motor 401, which is fixedly installed on the outer surface of the discharge cylinder 2.
