Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0023] In one embodiment, such as Figure 1-4 As shown, an assembly mechanism for a mini tiller includes a rotating shaft 1, and further includes:

[0024] The connecting block 3 connects the rotating shaft 1 to the output shaft of the micro-tiller. Both ends of the rotating shaft 1 are provided with mounting flanges 2, each with multiple mounting holes 20. Bolts passing through the mounting holes 20 securely mount the entire rotating shaft 1 onto the frame of the micro-tiller. The rotating shaft 1 has a mounting groove 13, with fixed plates 12 fixedly mounted on both sides inside the mounting groove 13. A connecting block 3 is positioned between the two fixed plates 12. The connecting block 3 is composed of two symmetrical semi-circular blocks joined together, and its modular structure facilitates subsequent installation, disassembly, and maintenance. A sleeve 18 is provided on the connecting block 3. The sleeve 18 is a hollow square sleeve, and an mounting plate 4 is provided inside the sleeve 18. One end of the mounting plate 4 is provided with a rotary tiller blade 5. The rotating shaft 1 is used to connect to the power output shaft of the micro-tiller to transmit torque, driving the rotary tiller blade 5 to rotate, thereby tilling the soil.

[0025] A fixing pin 9 is provided. Each of the two connecting blocks 3 has a locking block 15 on one side where they are close together. A insert plate 16 is provided between the two locking blocks 15. The two connecting blocks 3 are fitted inside the mounting groove 13 and interlocked. The two locking blocks 15 on the same side are in contact and aligned. The insert plate 16 is inserted into the slot 10 to fix the two locking blocks 15, thereby locking the two semi-circular connecting blocks 3 and preventing them from loosening. This ensures that the connecting blocks 3, as a whole, stably transmit torque. A through hole 19 is provided on the fixing plate 12, and a fixing pin 9 is provided inside the through hole 19. One end of the fixing pin 9 is provided with a spring piece 22, which is elastically installed by an elastic element. The other end of the fixing pin 9 is provided with a pressure block 14. A spring 21 is provided between the pressure block 14 and the fixing plate 12. The spring 21 is sleeved on the outside of the fixing pin 9 to provide preload for the fixing pin 9. During assembly, one end of the fixing pin 9 passes through the through hole 19 of the fixing plate 12 and further inserts through the round hole on the connecting block 3. The spring piece 22 pops out and snaps onto the outer side of the fixing plate 12, fixing the connecting block 3 and the fixing plate 12. At the same time, the fixing pin 9 passes through the mounting plate 4 to fix the mounting plate 4.

[0026] The connecting mechanism is connected to the sleeve 18 and can connect and reinforce the rotating shaft 1 and the sleeve 18.

[0027] The assembly mechanism of the rotary tiller installs the blades via a rotating shaft 1, connecting blocks 3, and a sleeve 18. Two semi-circular connecting blocks 3 are set in the mounting groove 13 of the rotating shaft 1, and are locked by inserting a plate 16. The mounting plate 4 with the blades is inserted into the sleeve 18 and inserted through the fixing pin 9, so that it passes through the corresponding holes on the fixing plate 12, connecting blocks 3, and mounting plate 4. The spring piece 22 automatically pops out and locks under the action of the elastic element, realizing the quick assembly of the rotary tiller blades. As an embodiment, the left, right, up, and down positions of the various components shown in the attached figure are only one arrangement method, and the specific positions are set according to specific needs.

[0028] In one embodiment, such as Figure 1-3 As shown, the connecting mechanism includes a support rod 7, a fixing ring 6, and a hinge seat 8. The hinge seat 8 is provided on the side wall of the sleeve 18, and the support rod 7 is rotatably mounted on the hinge seat 8. The fixing ring 6 is provided outside the rotating shaft and is located between two mounting grooves 13. The fixing ring 6 is rotatably connected to one end of the support rod 7. The fixing ring 6 pulls the sleeve 18 through the support rods 7 on both sides. When the micro-tiller is working, the rotary tiller blade 5 is subjected to the resistance of the soil and generates vibration and sway. Through the support rod 7 and the fixing ring 6, part of the impact force is transmitted to the rotating shaft 1, suppressing the vibration of the sleeve 18 and the mounting plate 4, and improving the stability of the blade operation.

[0029] In one embodiment, such as Figure 1-2 As shown, a fixing bolt 11 is provided on the outside of the rotating shaft 1. Both ends of the fixing bolt 11 pass through the fixing ring 6 and are provided with locking nuts, which lock the fixing ring 6 on the rotating shaft 1 and ensure the reliability of the connection.

[0030] In one embodiment, such as Figure 3-4 As shown, the locking block 15 is provided with a locking bolt 17. One end of the locking bolt 17 is inserted into the interior of the insert plate 16 to prevent the insert plate 16 from coming loose from the slot 10 during use, thereby enhancing the stability of the connecting blocks 3 after splicing.

[0031] In one embodiment, such as Figure 4 As shown, the card block 15 has a card slot 10 on its outside, and the insert plate 16 is inserted into the card slot 10.

[0032] The above embodiments of this utility model provide an assembly mechanism for a micro-tiller. Two semi-circular connecting blocks 3 are placed outside the mounting groove 13 of the rotating shaft 1, aligning the locking blocks 15 on the two connecting blocks 3 with each other. The insert plate 16 is inserted into the slots 10 of the two locking blocks 15, splicing and fixing the two connecting blocks 3 into a whole. The locking bolts 17 on the locking blocks 15 are rotated to prevent the insert plate 16 from loosening. The mounting plate 4 with the rotary tiller blades 5 is pushed into the square sleeve 18 on the connecting block 3. The fixing pin 9 passes through the fixing plate 12, the mounting plate 4, and the connecting blocks 3, simultaneously and firmly locking the fixing plate 12, the connecting blocks 3, and the mounting plate 4. The rotating shaft 1 is placed in the predetermined installation position, aligning the mounting flanges 2 at both ends with the mounting seats on the micro-tiller frame. Bolts are passed through the mounting holes 20 and tightened with nuts, firmly fixing the rotating shaft 1 to the frame.

[0033] Power is transmitted from the power output shaft of the micro-tiller to the rotating shaft 1, which can drive it to rotate. The rotational torque of the rotating shaft 1 is transmitted to the connecting block 3 through the fixed plate 12. The connecting block 3 is made up of two semi-circular blocks locked together as a rigid whole by the insert plate 16, so that the torque can be transmitted to the sleeve 18. The sleeve 18 drives the mounting plate 4 to rotate, and the rotary tillage blades 5 at the end of the mounting plate 4 perform rotary tillage.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
