For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0036] like Figure 1 , Figure 2 As shown, this embodiment provides a feeding auger with a clutch, comprising: a sprocket 100, a clutch 200, a shaft head 300, a transmission shaft 400, a roller body 500 and a blade 600;
[0037] The sprocket wheel 100 is connected to the clutch 200 by bolts, which provides a stable assembly position for the clutch 200. Also, due to the plug-in relationship between the clutch 200 and the shaft head 300, the sprocket wheel 100 is effectively prevented from jumping during the chain transmission process.
[0038] The shaft head 300 is inserted into the clutch 200, and the shaft head 300 is fixedly connected to the transmission shaft 400. The outer periphery of the transmission shaft 400 is provided with a roller body 500, and the roller body 500 forms a rotatable matching relationship with the transmission shaft 400. When the clutch 200 rotates with the rotation of the sprocket wheel 100, the shaft head 300 drives the transmission shaft 400 to rotate, and then the transmission shaft 400 drives the roller body 500 to rotate, thereby realizing effective power transmission.
[0039] During operation, if there is an emergency situation where fallen corn needs to be harvested or foreign objects are accidentally fed, the clutch 200 can promptly cut off the connection with the shaft head 300. This can effectively cut off the auger transmission, thereby protecting the entire auger system from damage and improving the safety of the entire device.
[0040] Blades 600 are evenly fixed on the outer surface of the roller body 500 to meet the requirement of stirring the material when the auger is in operation.
[0041] like Figure 3 , Figure 4 As shown, in an embodiment of the utility model, the clutch 200 includes a flange 201, which is connected to the sprocket 100 by bolts, a first through hole is evenly opened on the surface of the flange 201, and a second through hole is evenly opened on the surface of the sprocket 100 that is concentric with the first through hole. The first through hole and the second through hole are correspondingly arranged and connected by bolts.
[0042] A housing 202 is fixedly connected to one side surface of the center position of the flange 201, and a clutch body 203 is arranged inside the housing 202. A shaft head 300 is inserted into the center position of the clutch body 203 to drive the shaft head to rotate.
[0043] Pin holes 204 are evenly formed on the outer surface of the clutch body 203 , and grooves are formed on the inner surface of the housing 202 corresponding to the pin holes 204 . Elastic components 205 are disposed in the pin holes 204 .
[0044] Under normal operation, the elastic component 205 is inserted into the corresponding groove, the clutch body 203 rotates, and the protrusion on the elastic component 205 is inserted into the groove and drives the rotation;
[0045] When harvesting fallen corn or feeding foreign objects and needing to be cut off, the raised sliding pin 207 on the elastic component 205 retracts inward and does not contact the groove, the clutch body 203 stops rotating, and the shaft head 300 cuts off the transmission from the sprocket 100 and bounces to the next groove.
[0046] like Figure 5 , Figure 6As shown, the elastic component 205 includes a spring 206 disposed inside the pin hole 204 , a sliding pin 207 is disposed at the top of the spring 206 , and the sliding pin 207 abuts against a groove on the inner surface of the housing 202 .
[0047] The pin holes 204 are arranged in three parallel rows on the outer surface of the clutch body 203, and the number of the pin holes 204 in each row is greater than or equal to 12. According to the number of the table springs 206 and the sliding pins 207, a torque change of 1200N·m to 2000N·m can be achieved.
[0048] In the embodiment of the utility model, the center of the clutch body 203 is connected to the shaft head 300 by a spline hole. Compared with the prior art of directly connecting the shaft and the wheel with a flat key, the spline hole is more stable. The spline hole provides better torque transmission capacity and shear resistance, while reducing wear and failure caused by improper connection, ensuring the stable operation of the entire auger system.
[0049] The end of the roller body 500 close to the clutch 200 is also sleeved with a flange bearing 700, which provides a good sealing effect, preventing external pollutants and moisture from invading the inside of the bearing, thereby extending the service life of the bearing and improving the reliability of the entire auger.
[0050] The blade 600 is in a spiral shape or an arc plate shape. The spiral blade 600 is helpful to realize continuous material conveying and mixing, while the arc plate blade 600 is helpful to improve the mixing efficiency and uniformity of the material.
[0051] The outer surface of the blade 600 is covered with a corrosion-resistant layer, which can not only resist corrosion factors in various harsh environments, such as humidity, salt, etc., but also reduce the wear of the corn on the blade 600, maintain the integrity of the blade, and increase the service life.
[0052] The utility model also provides an ear picking and cutting platform, which comprises the above-mentioned feeding auger with a clutch.
[0053] Based on the above embodiments, the working process of a feeding auger with a clutch provided by the embodiment of the utility model is as follows:
[0054] When the agricultural machine is started, the sprocket wheel 100 is connected to the clutch 200 by bolts and starts to rotate. This rotational motion is transmitted to the internal shaft head 300 through the clutch, and then drives the transmission shaft 400 fixed to the shaft head 300 to rotate. As the transmission shaft 400 rotates, the roller body 500 also starts to rotate, and the blades 600 on the roller body perform stirring work to achieve material transportation and mixing. During the rotation process, the blades 600 effectively stir the material to meet the needs of material transportation and processing in agricultural harvesting.
[0055] Under normal operation, the sliding pin 207 inside the clutch 200 is protruding and inserted into the groove, and the sprocket 100 drives the flange 201, the housing 202 and the clutch 200 to rotate.
[0056] When the auger encounters an abnormal situation such as fallen crops or foreign objects causing a sudden increase in load during operation, the sliding pin 207 in the elastic component 205 retracts inward to squeeze the spring 206 and no longer contacts the groove, which causes the clutch body 203 and the shaft head 300 to stop rotating, thereby realizing the transmission cutoff between the roller body 500 and the sprocket 100.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
