DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-8 One embodiment of the present invention is: a trenching machine for tea planting, comprising a U-shaped frame 1, and further comprising: The baffle 2 is connected to the top right side of the U-shaped frame 1 and is used to block the mud; Two handles 3 are respectively connected to the top of the baffle 2; A trenching mechanism 4 is arranged in the U-shaped frame 1 and is used for trenching on the ground; The shielding mechanism 5 is arranged above the trenching mechanism 4 and is used to shield the flying mud when trenching; The adjusting mechanism 6 is arranged on the left side of the trenching mechanism 4, contacts the ground, and is used to adjust the trenching depth of the trenching mechanism 4; Wherein, the ditching mechanism 4 comprises: Two circular connecting plates 41 are fixedly connected to the right side of the U-shaped frame 1; The fixing sleeve 43 is connected to the circular connecting plate 41 through two connecting rods 42; The rotating shaft 45 is rotatably connected to the inner wall of the fixed sleeve 43 through the bearing 44; The adjusting plate 46 and the movable cover 47 are both mounted on the outer wall of the rotating shaft 45, and a plurality of blades 48 are mounted on the outer wall.

[0019] The ditching mechanism 4 also includes: A return spring 49 is disposed on the inner wall of the movable cover 47 and is used to push the adjustment disk 46 away from the movable cover 47 to expand the distance between the adjustment disk 46 and the movable cover 47; The middle part of the rotating shaft 45 is hexagonal, and the adjusting plate 46 and the movable cover 47 slide on the outer wall thereof; The regulating plate 46 moves in close contact with the inner wall of the movable cover 47 to prevent mud from entering the movable cover 47 .

[0020] The blades 48 on the adjusting disk 46 and the movable cover 47 are equidistantly distributed around the circumference, and adjacent blades 48 are arranged in opposite directions. The blades 48 on the adjusting disk 46 and the movable cover 47 are relatively staggered and arranged for rotary ditching.

[0021] A motor 7 is installed on the inner wall of the U-shaped frame 1 , and the output end of the motor 7 is transmission-connected to the outer wall of the rotating shaft 45 through a sprocket set 8 , so as to drive the rotating shaft 45 to rotate.

[0022] Working principle: When trenching the ground between adjacent tea trees, since there are many rhizomes at the bottom of the tea leaves, the rhizomes of the tea leaves need to be cut and trenched. First, the controller controls the motor 7 to work, and then drives the rotating shaft 45 to rotate through the sprocket group 8, and at the same time pushes the handrail 3 to push the trencher to move. When the rotating shaft 45 rotates, the adjusting disk 46 and the movable cover 47 installed on its outer wall are driven to rotate, and then the multiple staggered circumferences and staggered curved blades 48 are driven to rotate, so as to trench the ground and achieve the trenching effect; According to the width of the trench, the return spring 49 pushes the distance between the adjustment disk 46 and the movable cover 47 to expand, so that the working distance between the blades can be changed to achieve a wider trench, thereby improving the trenching effect.

[0023] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the shielding mechanism 5 includes: The retaining plate 51, the bottom of which is connected to the fixing sleeve 43 through four inclined fixing rods 52, is used to prevent the soil turned over by the ditching mechanism 4 from falling to both sides; A plurality of adjusting screws 53 are threadedly connected to the fixed sleeve 43 and respectively contact the outer walls of the adjusting disk 46 and the movable cover 47 to push the distance between the adjusting disk 46 and the movable cover 47; Two annular grooves 56 are respectively formed on the outer walls of the adjusting disk 46 and the movable cover 47 and are in contact with the adjusting screw 53 .

[0024] The shielding mechanism 5 also includes: The spring 54 is arranged in the convex groove of the inner wall of the adjusting screw 53; The sliding ball 55 is rollingly connected in the convex groove and is pushed outward by the spring 54; A plurality of grooves 57 are formed at equal intervals on the inner wall of the annular groove 56 and contact the sliding ball 55 to vibrate the adjustment plate 46 and the movable cover 47 .

[0025] Working principle: When a smaller groove needs to be opened, the adjusting screw 53 is rotated by the tool, thereby shortening the distance between the adjusting screw 53 and the adjusting disk 46 and the movable cover 47, thereby pushing the adjusting disk 46 and the movable cover 47 closer to each other, compressing the return spring 49 inside, shortening the rotation working range of the blade 48, and opening a smaller groove; At the same time, when the adjusting disk 46 and the movable cover 47 are rotating, the groove 57 in the annular groove 56 opened on the outer wall thereof continuously contacts the sliding ball 55 during rotation. At this time, under the push of the internal spring 54, the reset spring 49 is cooperated to continuously vibrate the adjusting disk 46 and the movable cover 47 to prevent the outer wall from adhering to the soil. At the same time, when trenching, the soil turned over by the rotating blade 48 contacts the earth retaining plate 51, and then can be thrown outward along the arc-shaped sides thereof, so as to fall into the two sides of the trenched trench, thereby improving the trenching effect.

[0026] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the adjustment mechanism 6 includes: Two extension rods 61 are fixedly connected to one side of the circular connecting plate 41; A roller 63 is hinged to one end of an arc-shaped rod 62, and the other end of the arc-shaped rod 62 is hinged to an extension rod 61, and is used to move the trencher; The lever 64 is fixedly connected to the outer wall of the arc-shaped rod 62 and is used to push the arc-shaped rod 62 to deflect around the hinge. The adjustment mechanism 6 also includes: A mounting groove 66 is provided on the outer wall of the extension rod 61; The fixed shaft 65 is fixedly connected in the mounting groove 66; The spring piece 67 is sleeved on the outer wall of the fixed shaft 65 , and its bottom is connected to the mounting groove 66 , and its top is in contact with the lever 64 , so as to push the lever 64 to move upward.

[0027] Working principle: When trenching, by pushing the trencher, at this time, under the push of the spring piece 67, the paddle 64 will be pushed to deflect, and then the right side of the arc rod 62 will be pushed downward around its hinge point to deflect downward, so that the roller 63 can contact the ground, so as to facilitate the movement of the entire trencher. When the handrail 3 is pressed down, the adjustment plate 46 and the movable cover 47 will move downward as a whole. At this time, the paddle 64 is pushed by the spring piece 67 or squeezed by the paddle, so that the arc rod 62 can be deflected, so that the roller 63 continues to contact the ground, so as to adapt to trenches of different depths for trenching and facilitate its movement.

[0028] The present invention provides a trenching machine for tea planting. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
