Description

A straw crushing component and crushing equipment Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a straw crushing component and crushing equipment. Background Technology

[0002] Driven by sustainable agricultural development and environmental protection policies, straw treatment has become an important part of agricultural production. Technologies such as straw crushing and returning to the field and straw feed utilization are key paths to achieve efficient straw conversion. As the core equipment for pretreatment, the performance of straw crushing equipment directly affects the subsequent utilization effect of straw.

[0003] Existing straw crushers mainly consist of a casing, a motor, and a single crushing roller. The motor directly drives the crushing roller to rotate at high speed, and the surface of the roller is covered with simple blades or tooth-like structures. During operation, straw is fed into the machine through the top inlet, and the rotation of the crushing roller directly crushes the straw.

[0004] However, without pretreatment of the straw during the crushing process, the straw is prone to tangling on the surface of the crushing roller, resulting in low crushing efficiency and even jamming. Summary of the Invention

[0005] This utility model provides a straw crushing component and crushing equipment, which can solve the problem in the prior art that straw is easily entangled on the crushing roller during crushing, affecting the crushing efficiency.

[0006] A straw crushing assembly includes a housing, a rolling shaft, and a crushing roller. The rolling shaft is rotatably disposed inside the housing, and the crushing roller is rotatably disposed on one side of the rolling shaft. A pressing roller is disposed on the other side of the rolling shaft. A plurality of cutting plates are disposed on the outer peripheral wall of the rolling shaft, and each cutting plate has a cutting end. The rotation direction of the rolling shaft is consistent with the direction of the cutting ends. A linkage mechanism is disposed between the rolling shaft and the crushing roller, and the linkage mechanism is used to drive the crushing roller to rotate synchronously with the rolling shaft.

[0007] According to one embodiment of the present invention, the linkage mechanism includes a first pulley, a second pulley and a first synchronous belt. The first pulley is rotatably disposed on the rolling shaft, and the second pulley is rotatably disposed on the crushing roller. The first synchronous belt is disposed between the first pulley and the second pulley.

[0008] According to one embodiment of the present invention, two pressing rollers are provided, and the pressing rollers are rotatably disposed inside the machine casing. The pressing rollers are used to press straw.

[0009] According to one embodiment of the present invention, a third pulley is rotatably arranged on the two pressing rollers, a fourth pulley is arranged on the rolling shaft, and a second synchronous belt is arranged between the fourth pulley and the third pulley.

[0010] According to one embodiment of the present invention, the pressing roller is provided with a plurality of pressing grooves, and an annular pressing plate is provided between adjacent pressing grooves.

[0011] According to one embodiment of the present invention, a transport mechanism is fixedly connected to the side wall of the casing. The transport mechanism includes a transport frame and transport rollers. The transport frame is fixedly installed on the side wall of the casing, and a plurality of transport rollers are rotatably installed on the transport frame. The transport rollers are used to transport straw.

[0012] According to one embodiment of the present invention, the pressing roller is rotatably disposed at the inlet and located inside the machine housing, and the inlet is connected to the transport roller.

[0013] According to one embodiment of the present invention, a plurality of crushing blades are provided on the outer peripheral wall of the crushing roller.

[0014] According to one embodiment of the present invention, the shredding blade is serrated.

[0015] This utility model also provides a straw crushing device, including a rotary motor, a frame and the straw crushing assembly described above. The rotary motor is fixedly mounted on the housing and its output end is connected to the rolling shaft. The housing is fixedly mounted on the top of the frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a rotary motor to drive a rolling shaft to rotate. As the rolling shaft rotates, a second synchronous belt drives a pressing roller to rotate synchronously. The pressing roller, located at the machine casing inlet, presses the straw conveyed by the transport roller. The pressing groove and the annular pressing plate increase the friction and pressing force on the straw, allowing it to smoothly enter the machine casing. Simultaneously, the rolling shaft drives the crushing roller to rotate via a linkage mechanism. As the rolling shaft rotates, the cutting end on the cutting plate first performs preliminary cutting of the straw, breaking it into shorter fragments. Then, the serrated crushing blades on the high-speed rotating crushing roller further crush the straw fragments, breaking them into smaller particles. This achieves multi-stage crushing of the straw, greatly improving crushing efficiency. Furthermore, the design of the pressing roller, pressing groove, and annular pressing plate effectively presses the straw, preventing slippage and jamming during feeding, ensuring that the straw can continuously and stably enter the crushing area, guaranteeing smooth crushing operations.

[0023] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0024] As shown in Figures 1 to 4, a straw crushing assembly includes a housing 1, a rolling shaft 2, and a crushing roller 3. The rolling shaft 2 is rotatably disposed inside the housing 1, and the crushing roller 3 is rotatably disposed on one side of the rolling shaft 2. A pressing roller 5 is disposed on the other side of the rolling shaft 2. A plurality of cutting plates 21 are disposed on the outer peripheral wall of the rolling shaft 2, and the cutting plates 21 are provided with cutting ends 22. The rotation direction of the rolling shaft 2 is consistent with the setting direction of the cutting ends 22. A linkage mechanism is provided between the rolling shaft 2 and the crushing roller 3, and the linkage mechanism is used to drive the crushing roller 3 to rotate synchronously with the rolling shaft 2.

[0025] The linkage mechanism includes a first pulley 4, a second pulley 41 and a first synchronous belt 42. The first pulley 4 is rotatably mounted on the rolling shaft 2, and the second pulley 41 is rotatably mounted on the crushing roller 3. The first synchronous belt 42 is disposed between the first pulley 4 and the second pulley 41.

[0026] When the rolling shaft 2 rotates, the first pulley 4 on it rotates accordingly, transmitting power to the second pulley 41 on the crushing roller 3 via the first synchronous belt 42, thereby driving the crushing roller 3 to rotate synchronously. The toothed structure of the first synchronous belt 42 meshes with the toothed grooves on the pulley, ensuring stable power transmission during the transmission process and keeping the rotational speeds of the rolling shaft 2 and the crushing roller 3 consistent.

[0027] Two pressing rollers 5 are provided, and the pressing rollers 5 are rotatably disposed inside the machine housing 1. The pressing rollers 5 are used to press the straw.

[0028] A third pulley 6 is rotatably mounted on the two pressing rollers 5, a fourth pulley 61 is mounted on the rolling shaft 2, and a second synchronous belt 62 is provided between the fourth pulley 61 and the third pulley 6.

[0029] The fourth pulley 61 on the rolling shaft 2 is connected to the third pulley 6 on the pressing roller 5 via the second synchronous belt 62. When the rolling shaft 2 rotates, the fourth pulley 61 rotates accordingly, transmitting power to the third pulley 6 via the second synchronous belt 62, thereby driving the pressing roller 5 to rotate. The transmission method of the second synchronous belt 62 ensures precise matching of the rotational speeds between the pressing roller 5 and the rolling shaft 2, making the rotational speed of the pressing roller 5 compatible with the rotational speed of the rolling shaft 2, thus meeting the needs of straw feeding and crushing.

[0030] The pressing roller 5 is provided with several pressing grooves 51, and annular pressing plates 52 are provided between adjacent pressing grooves 51. The pressing grooves 51 on the surface of the pressing roller increase the contact area with the straw. When the pressing roller 5 rotates, the pressing grooves 51 can better grip the straw, increase friction, and prevent the straw from slipping during pressing. The annular pressing plates 52 between adjacent pressing grooves 51 apply additional compaction force to the straw, so that the straw is further compacted before entering the crushing area, ensuring that the straw can be better stressed during crushing and improving the crushing effect.

[0031] A transport mechanism is fixedly connected to the side wall of the casing 1. The transport mechanism includes a transport frame 7 and transport rollers 71. The transport frame 7 is fixedly installed on the side wall of the casing 1, and a plurality of transport rollers 71 are rotatably installed on the transport frame 7. The transport rollers 71 are used to transport straw. The pressing roller 5 is rotatably installed at the inlet and located inside the casing 1. The inlet is connected to the transport rollers 71.

[0032] Two pressing rollers 5 are rotatably positioned inside the machine casing 1 at the inlet. When straw is conveyed to the inlet of the machine casing 1 by the transport roller 71, the pressing rollers 5 rotate under the drive of the second synchronous belt 62, using their own weight and the friction generated by rotation to press the straw. The pressing groove 51 increases the contact area between the pressing rollers 5 and the straw, while the annular pressing plate 52 further enhances the compaction effect on the straw, allowing the straw to be smoothly fed into the crushing area.

[0033] The outer peripheral wall of the crushing roller 3 is provided with a plurality of crushing blades 31; the crushing blades 31 are serrated. When the crushing roller 3 rotates, the crushing blades 31 on the outer peripheral wall of the crushing roller 3 rotate at high speed to cut the straw. The serrated blade design increases the contact area between the blade and the straw and the cutting ability. When the straw comes into contact with the blade, the serrations can penetrate the straw more effectively, tearing and crushing it into smaller particles.

[0034] A straw crushing device includes a rotary motor 8, a frame 9 and the aforementioned straw crushing assembly. The rotary motor 8 is fixedly mounted on the housing 1, and its output end is connected to the rolling shaft 2. The housing 1 is fixedly mounted on the top of the frame 9.

[0035] The straw crushing equipment is supported by a frame 9, with the casing 1 fixed to the top of the frame 9. A rotary motor 8 is mounted on the casing 1 and connected to the rolling shaft 2, providing power for the entire crushing process. Inside the casing 1, the rolling shaft 2 is rotatably mounted, with a crushing roller 3 mounted on one side and two pressing rollers 5 on the other side. Several cutting plates 21 are distributed on the outer peripheral wall of the rolling shaft 2, each with a cut end 22 aligned with the rotation direction of the rolling shaft 2. The rolling shaft 2 and the crushing roller 3 rotate synchronously through a linkage mechanism consisting of a first pulley 4, a second pulley 41, and a first synchronous belt 42. The third pulley 6 on the two pressing rollers 5 and the fourth pulley 61 on the rolling shaft 2 are connected and driven by the second synchronous belt 62. The surface of the pressing roller 5 is provided with a pressing groove 51 and an annular pressing plate 52. The side wall of the housing 1 is connected to a transport mechanism, which consists of a transport frame 7 and multiple transport rollers 71. The transport rollers 71 are rotatably mounted on the transport frame 7, and the pressing roller 5 is located at the entrance of the housing 1 and communicates with the transport rollers 71. The outer peripheral wall of the crushing roller 3 is equipped with serrated crushing blades 31.

[0036] The working principle of this invention is as follows: The rotary motor 8 is started, driving the rolling shaft 2 to rotate. As the rolling shaft 2 rotates, the pressing roller 5 rotates synchronously via the second synchronous belt 62. The pressing roller 5, located at the inlet of the machine casing 1, presses the straw conveyed by the transport roller 71. The pressing groove 51 and the annular pressing plate 52 increase the friction and pressing force on the straw, allowing it to smoothly enter the machine casing 1. Simultaneously, the rolling shaft 2 drives the crushing roller 3 to rotate via a linkage mechanism. As the rolling shaft 2 rotates, the cutting end 22 on the cutting plate 21 first performs preliminary cutting of the straw, breaking it into shorter fragments. Then, the serrated crushing blades 31 on the high-speed rotating crushing roller 3 further crush the straw fragments, breaking them into smaller particles. Throughout the crushing process, the transport mechanism continuously conveys the straw to the inlet, ensuring the continuity of the crushing operation. The crushed straw particles are discharged from the bottom of the machine casing 1.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
