[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-6 , an automatic weeder for fruit planting, comprising a base plate 1, a handle 2 is arranged on the top of the same side of the base plate 1, and moving wheels 3 are arranged at both ends, a first side plate 4 and a second side plate 5 are respectively connected to the two ends of the other side of the base plate 1, a cover body 6 is connected between the first side plate 4 and the second side plate 5, a first rotating shaft 7 is rotatably connected in the first side plate 4, a second rotating shaft 8 is rotatably connected in the second side plate 5, a weeding mechanism 9 is connected between the second rotating shaft 8 and the first rotating shaft 7, a diesel engine 10 is arranged on the base plate 1, the diesel engine 10 and the first rotating shaft 7 are connected and transmitted through a first pulley group 11 and a first belt 12, a linkage mechanism 13 is connected to the second rotating shaft 8, a cleaning mechanism 14 is arranged on the base plate 1, and the cleaning mechanism 14 and the linkage mechanism 13 are connected and transmitted through a second pulley group 15 and a second belt 16.

[0031] The weeding function is achieved through the connection between the diesel engine 10 and the weeding mechanism 9, and the transmission connection through the linkage mechanism 13 enables the weeding mechanism 9 to prevent the weeds from being broken and entangled during the weeding process. Through the connection between the linkage mechanism 13 and the cleaning mechanism 14, during the weeding process of the weeding mechanism 9, the linkage mechanism 13 drives the cleaning mechanism 14 to drive, so that the soil attached to the inner side of the cover body 6 falls off, thereby effectively saving the operation of later cleaning.

[0032] Reference Figure 3-4 and Figure 6 The weeding mechanism 9 is composed of a first rotating disk 91, a second rotating disk 92, a reciprocating screw rod 93, a guide rod 94, a cutter shaft 95 and a cutter 96. The two ends of the reciprocating screw rod 93 are respectively connected to the first rotating shaft 7 and the second rotating shaft 8. The cutter shaft 95 is transmission-connected to the reciprocating screw rod 93. The cutter 96 is installed on the outer wall of the cutter shaft 95. The first rotating disk 91 is rotatably connected to the first rotating shaft 7 and is located on the inner side of the first side plate 4. The second rotating disk 92 is rotatably connected to the second rotating shaft 8 and is located on the inner side of the second side plate 5. The guide rod 94 passes through the cutter shaft 95 and is connected between the first rotating disk 91 and the second rotating disk 92.

[0033] Reference Figure 3-4The linkage mechanism 13 is composed of a housing 131, a first bevel gear 132, a second bevel gear 133, a third bevel gear 134 and a connecting pipe 135. The housing 131 is connected to the outer side of the second side plate 5. The first bevel gear 132 is rotatably connected to the inner wall of one side of the housing 131. The second bevel gear 133 is connected to the extended section of the second rotating shaft 8 and meshes with the first bevel gear 132. The connecting pipe 135 is rotatably connected to the outer wall of the extended section of the second rotating shaft 8, one end of which is connected to the third bevel gear 134, and the other end is connected to the second turntable 92. The third bevel gear 134 meshes with the first bevel gear 132 and is symmetrical with the second bevel gear 133.

[0034] Reference Figure 5 The cleaning mechanism 14 is composed of a support plate 141, a linkage shaft 142, a cam 143, a connecting ear plate 144, a spring 145 and a knocking hammer 146. The support plate 141 is connected to the base plate 1, the linkage shaft 142 is rotatably connected in the support plate 141, the cam 143 is connected to the linkage shaft 142, the connecting ear plate 144 is connected to the cover body 6, the knocking hammer 146 is rotatably connected to the connecting ear plate 144, one end of which is in contact with the cover body 6, and the other end is located below the rotation diameter of the cam 143. One end of the spring 145 is connected to the base plate 1, and the other end is connected to the bottom end of the knocking hammer 146 away from the cover body 6.

[0035] After the diesel engine 10 is started, the first rotating shaft 7 rotates through the cooperation of the first pulley set 11 and the first belt 12, and the first rotating shaft 7 drives the reciprocating screw rod 93 and the second rotating shaft 8 to rotate synchronously in the same direction. At the same time, the second rotating shaft 8 drives the second bevel gear 133 to rotate. Since the housing 131 is connected to the second side plate 5 and is in a relatively fixed state, the second bevel gear 133 drives the first bevel gear 132 to rotate on the inner wall of the housing 131, and the first bevel gear 132 drives the third bevel gear 134 to rotate, and the rotation direction is opposite to the rotation direction of the second bevel gear 133. The connection of the connecting tube 135 makes the second rotating disk 92, the guide rod 94 and the first rotating disk 91 rotate synchronously, and the rotation direction is opposite to that of the reciprocating screw rod 93. The cutter shaft 95 rotates under the toggle of the guide rod 94, so that the cutter 96 performs a circular motion to achieve a weeding effect. Since the guide rod 94 and the reciprocating screw rod 93 rotate in opposite directions, the cutter shaft 95 and the reciprocating screw rod 93 rotate in opposite directions. Relatively speaking, the cutter shaft 95 performs a rapid reciprocating movement on the reciprocating screw rod 93 to achieve a horizontal shearing effect, effectively preventing the problem of entanglement after the weeds are broken;

[0036] When the second rotating shaft 8 rotates, the linkage shaft 142 rotates through the connection between the second pulley group 15 and the second belt 16. The cam 143 generates a circular motion under the drive of the linkage shaft 142, and cyclically knocks the knocking hammer 146. The knocking hammer 146 knocks the cover body 6 through the connection of the connecting ear plate 144. Under the elastic force of the spring 145, the cam 143 contacts the knocking hammer 146, causing the spring 145 to be compressed. When the cam 143 and the knocking hammer 146 are separated, the elastic force of the spring 145 forces the connecting end of the knocking hammer 146 to rise, and the opposite end of the knocking hammer 146 close to the cover body 6 descends, knocking the cover body 6, causing the cover body 6 to vibrate, effectively preventing soil from adhering to the inner wall of the cover body 6.

[0037] Reference Figure 1 The front ends of the first side plate 4 and the second side plate 5 are both connected with side ear plates 17, and the bottom ends of the side ear plates 17 are rotatably connected with auxiliary wheels 18, so as to facilitate the steering effect of the lawn mower.

[0038] Reference Figure 3 and Figure 6 The first rotating disk 91, the second rotating disk 92 and the two ends of the cutter shaft 95 are all rotatably connected with connecting rings 97, and the single-sided cross-section of the connecting ring 97 is L-shaped. The same first corrugated hose 98 is connected between two adjacent connecting rings 97. The two first corrugated hoses 98 are both sleeved on the reciprocating screw rod 93. The first corrugated hose 98 protects the reciprocating screw rod 93 to prevent the damage to the reciprocating screw rod 93 caused by splashing soil. At the same time, the retractable performance of the first corrugated hose 98 ensures the maintenance effect of the protection of the reciprocating screw rod 93 during the movement of the cutter shaft 95, and ensures the independence of the reverse rotation between the first rotating disk 91 and the cutter shaft 95 under the connecting action of the connecting ring 97, preventing the first corrugated hose 98 from being affected.

[0039] Reference Figure 3 and Figure 6 A second corrugated hose 99 is sleeved on the guide rod 94, and the second corrugated hose 99 is connected to the first turntable 91 and the cutter shaft 95, as well as the second turntable 92 and the cutter shaft 95. The second corrugated hose 99 protects the guide rod 94. At the same time, the retractable performance of the second corrugated hose 99 ensures that the protection of the guide rod 94 is maintained during the movement of the cutter shaft 95.

[0040] Reference Figure 3-4 A positioning shaft 136 is connected to the inner wall of the housing 131, and the first bevel gear 132 is rotatably connected to the outer wall of the positioning shaft 136, providing a positioning effect for the rotation of the first bevel gear 132 and ensuring the stability of the meshing transmission.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
