Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a device for efficiently crushing and returning crop straw to the field. Background Art

[0002] Agricultural waste resources are huge. For example, according to survey statistics, the total amount of straw produced by the national agricultural reclamation system in 2015 was 54.1 million tons, of which 34.65 million tons were cereal straw, accounting for 86% of the total straw. The treatment and utilization of these straws have always been an important issue in agricultural production. As agricultural waste, if straw can be fully utilized as a resource, it can not only replace the use of some traditional fossil energy, but also contribute to the development of circular agriculture, which is the fundamental way to sustainable agricultural development.

[0003] In the prior art, during the operation of returning crop straw to the field, the blade, as a core component, is directly responsible for cutting and crushing the straw. However, the blade is easily damaged or destroyed when facing hard foreign objects such as stones and wires, thereby affecting the overall performance and operating efficiency of the device. Although the blades of straw returners are generally made of 65Mn steel and heat-treated to improve wear resistance and life, their strength and hardness may still be insufficient when encountering hard foreign objects such as stones or wires, resulting in blade damage. After the blade is damaged, the cutting and crushing effects of the device will be affected, resulting in incomplete straw crushing and affecting the returning to the field effect; the fan in some crop straw crushing devices may use a separate motor to drive the fan to ensure that it has sufficient power for scattering operations. Additional motors require additional motors and control systems, which increases the cost of the device and increases the volume and weight of the device, which may bring a certain degree of inconvenience to movement and operation.

[0029] The bearing mechanism 100 includes a crushing bucket 101, and a connecting block 102 is fixedly connected to one side of the outer surface of the crushing bucket 101;

[0030] The crushing bucket 101 is used to support the connecting block 102 .

[0031] The crushing mechanism 200 includes a motor frame 201 fixedly mounted on the other side of the outer surface of the crushing bucket 101, and a motor 202 is adapted to be mounted on the inner surface of the motor frame 201, and the output end of the motor 202 penetrates the inner surface of the crushing bucket 101;

[0032] The motor frame 201 is used to install the motor 202 .

[0033] The transmission mechanism 300 includes a fan slot 301 formed on one side of the inner surface of the crushing bucket 101 . A fan shaft 302 is fixedly connected to the surface of the fan slot 301 via a bearing. One end of the fan shaft 302 penetrates the outer surface of the crushing bucket 101 .

[0034] The fan slot 301 is used to support the fan shaft 302 .

[0035] Specifically, the bearing mechanism 100 further includes a connecting column 103 fixedly connected to the surface of the connecting block 102 , a connecting rod 104 is hingedly connected to the surface of the connecting column 103 , and the other end of the connecting rod 104 is fixedly connected to the head of the tractor.

[0036] When in use, the connecting rod 104 is driven to move by starting the tractor, and then the connecting rod 104 drives the connecting column 103 to move, and the crushing bucket 101 is driven to move through the cooperation between the connecting column 103 and the connecting block 102.

[0037] In summary, the supporting mechanism 100 can support the components of the crushing mechanism 200 and the transmission mechanism 300 , so that the crushing mechanism 200 and the transmission mechanism 300 can be used in coordination with each other.

[0038] Example 2

[0041] The motor 202 is used to drive the crushing roller 203 , and the crushing roller 203 is used to support the fixing block 204 .

[0042] Furthermore, the crushing mechanism 200 also includes a rotary column 205 fixedly connected to the inner surfaces of the two fixed blocks 204 , three movable blades 206 of different shapes are fixedly connected to the surface of the rotary column 205 , and a push rod 207 is fixedly connected to one side of the inner surface of the crushing bucket 101 .

[0043] The fixed block 204 is used to support the rotary column 205, and the push rod 207 is used to push down the taller straws so as to crush them.

[0044] When in use, the output end of the motor 202 rotates, driving the crushing roller 203 and the fixed block 204 on its surface to rotate, and then the fixed block 204 and the rotary column 205 cooperate to drive the movable blade 206 to rotate. At the same time, the centrifugal force transmitted to the blade by the inertia of the rotation of the crushing roller will make the movable blade form a shape similar to a flywheel, thereby making the cutting smoother. This stability helps to reduce vibration and noise, thereby improving the cutting accuracy and efficiency.

[0045] In summary, the crushing mechanism 200 can crush the straw efficiently. At the same time, through the design of the movable blade 206, when the blade collides with hard foreign objects such as stones and wires, the impact force caused by the hard foreign objects on the blade can be resolved to a certain extent. The centrifugal force transmitted to the blade by the inertia of the rotation of the crushing roller 203 will make the movable blade form a flywheel-like effect, making the cutting smoother. This stability helps to reduce vibration and noise, thereby improving the cutting accuracy and efficiency.

[0053] The connecting shaft 306 is used to connect the output end of the motor 202 and the crawler belt 308, so that the output end of the motor 202 can drive the connecting shaft 306 to rotate, and the discharge port 309 is used to discharge the crushed straw.

[0054] When in use, the output end of the motor 202 cooperates with the crawler to drive the connecting shaft 306 to rotate on the inner surface of the fixed frame 305, and then the connecting shaft 306 cooperates with the second bevel gear 307 to drive the first bevel gear 303 and the fan shaft 302 to rotate on the inner surface of the fan slot 301, so that the fan shaft 302 drives the fan 304 to rotate, and then the fan 304 blows the crushed straw from the discharge port 309 to the land surface, thereby completing the straw crushing and returning work to the field.
