Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1-8This is the first embodiment of the present invention, which provides an example of a multi-functional rotary tillage harvester, including a main frame 101. The upper right end face of the main frame 101 has a U-shaped limiting groove 207 with an opening to the right. A detachable harvester head 104 is provided within the limiting groove 207. The upper left end face of the harvester head 104 has a U-shaped locking cavity 209 with an opening to the upward. A sliding cavity 302 is provided within the upper wall of the limiting groove 207. A movable translation plate 301 is provided within the sliding cavity 302, and the lower end face of the translation plate 301 is fixed. A translation opening 300 is provided, which extends into the locking cavity 209. A movable pin 102 is fixedly provided on the upper end face of the translation plate 301, which extends to the outside of the upper end face of the main frame 101. Sliding springs 303 are respectively provided between the upper end faces of the left and right sides of the translation plate 301 and the upper walls of the left and right sides of the sliding cavity 302. A material trough 305 with a right-facing opening and a U-shaped opening is provided on the lower right end face of the main frame 101. A movable positioning groove 201 is provided in the material trough 305. A grain collection box 105 is fixedly provided on the lower end face of the positioning groove 201.

[0030] A rotating shaft 106 extends from the front and rear ends of the lower side of the main frame 101. A detachable rotary tiller head 107 is provided on the front and rear sides of the rotating shaft 106. A connecting cavity 108 is provided through the front and rear of the rotary tiller head 107. The rotating shaft 106 extends into the connecting cavity 108. A fixing groove 203 with a downward opening is provided on the upper wall of the connecting cavity 108. A translation cavity 205 with an upward opening is provided on the upper end face of the rotating shaft 106. A locking groove 200 is provided through the side wall of the translation cavity 205 away from the main frame 101. A movable fixing block 109 is provided in the translation cavity 205. The upper side of the fixing block 109 extends into the fixing groove 203. A locking plate 202 is fixed on the side of the fixing block 109 away from the main frame 101. The locking plate 202 extends through the locking groove 200 to the outside of the rotating shaft 106. A translation spring 204 is provided between the lower end face of the fixing block 109 and the lower wall of the translation cavity 205.

[0031] When it is time to harvest rice, first push the positioning groove 201 along the material trough 305, which in turn moves the grain collection box 105 to the left. Then, place the harvester head 104 into the rotary tiller head 107. The rotary tiller head 107 initially restricts the position of the harvester head 104. At the same time, the translation plate 301 moves downward under the action of the sliding spring 303, which in turn moves the translation opening 300 downward, so that the translation opening 300 moves into the locking cavity 209, allowing the harvester head 104 to enter. The first step involves tightening the bolts on the upper right side of the main frame 101 to completely secure the harvester head 104, simultaneously locking the grain collection box 105 in place to prevent it from falling off. This completes the assembly of the harvesting mechanism. When tilling is required, the rotating shaft 106 is inserted into the engagement cavity 108, allowing the rotary tiller head 107 to be mounted on the rotating shaft 106. Simultaneously, the fixing block 109 moves upward under the action of the translation spring 204, thereby securing the fixing block... 109 moves into the fixing slot 203, thereby fixing the position of the rotary tiller head 107, thus achieving rapid fixing and assembly of the rotary tiller head 107. When it is necessary to move the main frame 101, loosen the bolts on the upper right side of the main frame 101, and then pull the movable pin 102 upward, thereby causing the translation plate 301 to move upward, thereby driving the translation opening 300 to move upward, thereby causing the translation opening 300 to leave the locking cavity 209, and thus allowing the harvester head 104 to move towards the... Move to the right, thereby removing the harvester head 104, which in turn allows the grain collection box 105 to be removed to the right. Then, push the locking plate 202 downward, which in turn moves the fixing block 109 downward, causing the fixing block 109 to leave the fixing groove 203, thereby allowing the rotary tiller head 107 to be disassembled. This enables the rapid disassembly and assembly of the rotary tillage and harvesting mechanisms, thereby reducing the overall weight of the main frame 101, making it easier to transport in sections, reducing workload, and facilitating its transport between terraced fields.

[0032] Example 2

[0033] Reference Figure 1-8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the front and rear side walls of the limiting slot 207 are provided with a transmission groove 208. A connecting groove 304 is provided between the transmission groove 208 and the limiting slot 207. A detachable transmission screw 103 is provided in the transmission groove 208. The front and rear end faces of the harvester head 104 are respectively fixed with a movable connecting rod 206. The movable connecting rod 206 connects the transmission screw 103 and the harvester head 104 through the connecting groove 304.

[0034] When the harvester head 104 is moved to the left for installation, the moving connecting rod 206 will move to the left, which in turn will drive the transmission screw 103 to move to the left. This restricts the forward and backward displacement of the harvester head 104 through the two transmission screws 103, while further fixing the harvester head 104, increasing the contact area between the harvester head 104 and the main frame 101, increasing the force-bearing area of ​​the harvester head 104, preventing damage to the harvester head 104 during use, and thus increasing its service life.

[0035] Example 3

[0036] Reference Figure 1-8 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the lower left end face of the main frame 101 is fixed with the rear support rod 306, and the upper right end face of the grain collection box 105 is in contact with the harvester head 104.

[0037] When the grain collection box 105 and the harvester head 104 are installed in place, the upper right side of the grain collection box 105 contacts the harvester head 104, thereby supporting the harvester head 104 and preventing it from sagging due to its own weight during use. At the same time, when the main frame 101 is not working, it can be supported by the rear support rod 306. When it is necessary to replace the rotary tiller head 107, the left side of the main frame 101 can be pressed down at an angle, so that the rear support rod 306 and one side of the rotary tiller head 107 form two support points, thereby lifting the other side of the rotary tiller head 107, which facilitates the disassembly and assembly of the rotary tiller head 107.

[0038] The above are only specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of this utility model are covered by the patent scope of this utility model.
