Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1-3, an anti-tangling structure of a ditcher comprises a speed reducer 7 and cutter heads 2 arranged on two sides of the speed reducer 7, wherein two ends of a driving shaft 71 of the speed reducer 7 respectively penetrate out from two sides of a speed reducer box 72, and the two cutter heads 2 are respectively sleeved on two ends of the driving shaft 71 in a synchronous rotating manner through shaft sleeves 5.
One side of each cutter head 2 close to the reducer box body 72 is provided with a cutter head anti-winding cover 81 which synchronously rotates with the cutter head anti-winding cover, two sides of the reducer box body 72 are fixedly provided with box body anti-winding covers 82 which are respectively matched with the corresponding cutter head anti-winding covers 81, the box body anti-winding covers 82 are all disc-shaped structures with the diameters larger than or equal to the diameters of the adjacent cutter heads 2, and the outer edge of the anti-winding cover 82 of the box body is turned over towards the direction close to the adjacent anti-winding cover 81 of the cutter head to form an anti-winding fixed baffle ring 821, the outer edge of the anti-winding cover 81 of the cutter head is turned over towards the direction close to the adjacent anti-winding cover 82 of the box body to form an anti-winding movable baffle ring 811 matched with the adjacent anti-winding fixed baffle ring 821, the anti-winding fixed baffle ring 821 and the anti-winding movable baffle ring 811 are both in a circular ring structure, the anti-winding movable baffle ring 811 extends into the inner side of the corresponding anti-winding fixed baffle ring 821, so that an anti-winding gap A is formed between the two, in the embodiment, the diameter of the anti-winding gap A is larger than that of the cutter head 2, the exposed driving shaft 71 between the cutter head 2 and the reduction box body 72 is protected by arranging a large-sized cutter head anti-winding cover 81 and a box body anti-winding cover 82, meanwhile, by arranging the anti-winding gap A, the rotation of the cutter head 2 and the cutter head anti-winding cover 81 can not be interfered, and the complete entering of weeds can be effectively avoided, so that the drive shaft 71 is not entangled by weeds, ensuring that the ditcher can operate continuously and efficiently, specifically, thinner weeds are usually shorter, because the diameter of the cutter head anti-winding cover 81 and the box body anti-winding cover 82 is larger, even if part of thin weeds enters the anti-winding gap A, the thin weeds can not reach the driving shaft 71, so that it is not torn or broken by the rotation of the drive shaft 71 and thus does not get entangled on the drive shaft 71, whereas longer grass is generally thicker, due to the small width of the anti-tangling gap A, thick weeds cannot extend into the anti-tangling gap A at all.
In this embodiment, the width of the entrance of the anti-winding gap a is 1mm to 5mm, so that the cutter head anti-winding cover 81 and the box body anti-winding cover 82 do not interfere with each other, and large foreign matters can be prevented from entering.
Referring to fig. 3, at least one reinforcing fixed baffle ring 822 is disposed on one side of the anti-winding cover 82 of the casing close to the adjacent anti-winding cover 81 of the cutter head, each reinforcing fixed baffle ring 822 is disposed inside the anti-winding fixed baffle ring 821 with a diameter gradually decreasing, at least one reinforcing movable baffle ring 812 is disposed on one side of the anti-winding cover 81 of the casing close to the adjacent anti-winding cover 82 of the cutter head, each reinforcing movable baffle ring 812 is disposed inside the anti-winding movable baffle ring 811 with a diameter gradually decreasing, each reinforcing fixed baffle ring 822 and anti-winding fixed baffle ring 821 are alternately arranged with each reinforcing movable baffle ring 812 and anti-winding movable baffle ring 811, so that the anti-winding gap a forms a wave-shaped structure bending back and forth, and the structure of the anti-winding gap a is ingenious, like a labyrinth, which can completely stop passage of weeds, and ensure that no weeds are present on the driving shaft 71 between the anti-winding cover 81 of the cutter head and the anti-winding cover 82 of the casing.
Further, the central position of the box body anti-winding cover 82 is provided with an anti-winding cover mounting boss 823 protruding towards the reduction box body 72, and the anti-winding cover mounting boss 823 is integrally formed on the box body anti-winding cover 82 through a stamping process and is fixedly connected with the reduction box body 72 through a welding process.
Referring to fig. 1 to 3, the cutter head anti-winding covers 81 are all in a circular ring structure and are all installed on the inner side of the cutter head 2 along the outer edge of the adjacent cutter head 2, so that the diameter of the cutter head anti-winding cover 81 is as large as possible, and thus short weeds cannot enter the anti-winding gap a at all.
Referring to fig. 1, at least one passive mowing blade 83 is disposed in front of the reducer case 72, and both ends of the passive mowing blade 83 are respectively and fixedly connected to the side of the corresponding case anti-winding cover 82 away from the adjacent cutterhead anti-winding cover 81, so long as the cutting edge of the passive mowing blade 83 is sharp enough, weeds wound toward the reducer case 72 can be cut off once contacting the cutting edge of the passive mowing blade 83, and the weeds can be effectively prevented from being wound on the reducer case 72. Further, there are at least two passive mowing blades 83, and the distance between each passive mowing blade 83 and the bottom of the reducer case 72 in the vertical direction gradually increases, that is: the height of each passive mowing blade 83 is different. The blade of the passive mowing blade 83 with the highest mounting position faces downwards, and the blade of the passive mowing blade 83 with the lowest mounting position faces forwards, so that weeds in all directions can be cut more efficiently, and the weeds are prevented from being wound on the reducer case body 72.
In this embodiment, the number of the passive mowing blades 83 is three, the blade of the passive mowing blade 83 positioned at the highest position faces downward, and the blades of the passive mowing blades 83 positioned at the lowest position and in the middle face forward, so that the entangled weeds can be cut more easily.
The passive mowing blades 83 are of long-strip-shaped sheet structures, the two ends of the passive mowing blades 83 are bent to form mowing blade mounting seats 831, and the mowing blade mounting seats 831 can be fixed on the corresponding box anti-winding covers 82 through screws, so that the passive mowing device is simple, reliable and easy to machine, form and assemble.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
