[0002] Sesame is one of the important oil crops in my country. It has high nutritional value, health value and beauty value. It is widely used in food, medical care and other aspects. It has a large planting area in my country and has good economic benefits.

[0003] During the growth of sesame, a large number of weeds will grow between the rows due to sufficient sunlight. It is usually necessary to use a weeder to remove the weeds between the rows to ensure the soil is dry and thus ensure the sesame yield.

[0004] However, the frames of current sesame weeders are generally fixed structures, and cannot be adjusted for applicability according to the different row spacings of sesame planting. As a result, the wheels may get too close to the sesame seeds and crush them during forward movement. This requires that the row spacing must be precisely controlled during sesame planting. In addition, current sesame weeders generally cannot change the overall height of the frame according to the growth height of sesame seeds, and the frame is prone to scratching the tip of the sesame seeds, which affects the convenience, flexibility and weeding quality of sesame weeding operations and needs to be improved.

DETAILED DESCRIPTION

[0021] Example 1, see the attached specification Figure 1-2 4. An X-shaped bidirectional adjustment frame for a weeder, comprising a first frame beam 11 and a second frame beam 12 of the same size, the first frame beam 11 and the second frame beam 12 are rotatably connected to each other in the middle to form an X-shaped frame body, both ends of the first frame beam 11 and the second frame beam 12 are provided with walking wheel brackets 14, rollers are installed on the walking wheel brackets 14 to form a complete walking frame, and a locking mechanism after the frame is deformed is connected between the ends of both sides of the first frame beam 11 and the second frame beam 12. After the first frame beam 11 and the second frame beam 12 rotate relative to each other, they are deformed and the width is changed. The frame after the width is changed is locked by the locking mechanism, and a weeding bracket 15 is connected between the lower ends of the first frame beam 11 and the second frame beam 12, and the weeding frame is used to install the weeding mechanism.

[0022] like Figure 4 As shown, the first frame beam 11 includes a beam body A 111 and a beam body B 112, the inner ends of the beam bodies A 111 and B 112 are fixedly connected by two ear plates 113, the beam bodies A 111 and B 112 have the same size, a swing hole is formed between the ear plates 113 and the inner end surfaces of the two beam bodies, the second frame beam 12 is rotatably connected in the swing hole by a pin shaft 114, and the second frame beam 12 swings within the size range of the swing hole.

[0023] A circular reinforcement portion 121 is provided in the middle of the second frame beam 12, and the pin 114 passes through the center of the circular reinforcement portion 121. The circular reinforcement portion 121 is designed to improve the support strength of the middle portion of the second frame beam 12 when it rotates. The upper and lower end surfaces of the circular reinforcement portion 121 are respectively fitted with the inner surfaces of the two ear plates 113, which can improve the precision and stability of the frame. The walking wheel bracket 14 and the first frame beam 11 or the second frame beam 12 are set as a relatively rotatable structure.

[0024] When the frame of the present embodiment is used and adjusted, the locking mechanism for the first frame beam 11 and the second frame beam 12 is first released, and the two frame beams are rotated toward or oppositely to adjust the spacing between the outer ends of the frame beams, thereby adjusting the overall width of the frame. After the width is adjusted, the two frame beams are locked again by the locking mechanism, and the overall width of the frame can be quickly changed by relative rotation to accurately match the row spacing size of sesame, thereby avoiding the phenomenon of sesame being crushed during weeding.

[0025] Example 2, see the attached specification Figure 2-5 The locking mechanism in the first embodiment is configured to include a rod body A 161, a rod body B 162 and a sleeve rod 163. The outer end of the rod body A 161 is hinged to the end of the first frame beam 11, and the outer end of the rod body B 162 is hinged to the end of the second frame beam 12. The sleeve rod 163 is sleeved between the inner ends of the rod body A 161 and the rod body B 162. When the width of the first frame beam 11 and the second frame beam 12 is adjusted, the two rod bodies move toward or oppositely in the sleeve rod 163. As the length of the frame beam is adjusted, after the frame width is adjusted to the right position, the rod body and the sleeve rod 163 are locked by a set screw to achieve overall locking of the frame. First set screws 164 are provided at both ends of the sleeve rod 163.

[0026] In this embodiment, the weeding bracket 15 is fixedly connected between the sleeve rods 163 on both sides through a vertical rod. The two side beams of the weeding bracket 15 are both set as telescopic side beams 17. The ends of the telescopic side beams 17 are provided with second fixing screws 171. When the width of the frame is adjusted, the weeding bracket 15 also needs to change its width to avoid conflict. The design of the telescopic side beams 17 can realize that the weeding bracket 15 changes its width along with the frame.

[0027] The vertical rod includes a square tube rod 181 and a lifting rod 182 fixedly connected to the sleeve tube. The lifting rod 182 is slidably mounted in the square tube rod 181, and a driver is provided between the square tube rod 181 and the lifting rod 182. The driver is an electric push rod 183. The lower end of the electric push rod 183 is hinged to the lower end of the lifting rod 182, and the upper end is hinged to the upper end of the square tube rod 181. The lifting rod 182 can be driven to slide up and down in the square tube rod 181 by the electric push rod 183, thereby changing the height of the weeding bracket 15 between the lifting rods 182.

[0028] When the width of the frame in this embodiment is adjusted, the second fixing screw 171 on the side beam of the weeding bracket 15 is first loosened, and the telescopic side beam 17 is telescoped as the width of the frame changes, so that the width of the weeding bracket 15 is adapted to the width of the frame. When the height of the weeding bracket 15 needs to be changed, the electric push rod 183 is started to drive the lifting rod 182 to slide in the square tube rod 181. The height of the weeding bracket 15 can be adjusted to adapt to the height of the sesame during weeding to avoid scratching the sesame, which has excellent flexibility and convenience.
