[0002] A trench opener, as the name suggests, is a device used to dig trenches. It is mainly installed on agricultural vehicles or excavators. Its agricultural use is generally to dig trenches or loosen the land to facilitate the sowing of crops. Its industrial use is generally installed on excavators to dig deeper and longer trenches to facilitate the laying of pipelines or cables. The working principle is mainly to rely on the motor to drive the rotating head or rotating disk to rotate and dig out the soil on the ground.

[0003] Grooving openers are generally installed on agricultural vehicles or excavators. Sometimes different trench openers need to be replaced according to actual conditions and requirements. However, existing trench openers basically need to be manually installed and disassembled by workers, which has high labor intensity. In addition, the installation and disassembly of most trench openers are relatively complicated, resulting in a long time for replacing the trench openers, which greatly reduces the working efficiency of the trench openers.

[0004] Based on the above situation, the utility model provides a trench opener which is easy to disassemble and assemble. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0024] Example 1

[0025] A trench opener that is easy to disassemble and assemble, such as Figure 1-Figure 6 As shown, it includes a connecting seat 1, a connecting thick plate 2, a rotating head 3, a large motor 4, a threaded cap 5, a telescopic mechanism and a simple disassembly and assembly mechanism. The connecting seat 1 is provided with a telescopic mechanism at the bottom, the telescopic mechanism is provided with a simple disassembly and assembly mechanism at the bottom, the simple disassembly and assembly mechanism is provided with a connecting thick plate 2 at the bottom, the left and right sides of the connecting thick plate 2 are provided with square holes symmetrically distributed front and back, the bottom of the connecting thick plate 2 is fixedly connected to a large motor 4, the output end of the large motor 4 is fixedly connected to a rotating head 3, wherein the connecting thick plate 2 and the top of the telescopic mechanism are provided with threaded rods for fixed connection, and the threaded cap 5 can be threadedly connected with the threaded rods on the telescopic mechanism and the connecting thick plate 2.

[0026] like Figure 3 and Figure 4 As shown, the telescopic mechanism includes a telescopic cylinder 6 and a rounded corner plate 7. The telescopic cylinder 6 is slidably connected to the bottom of the connecting seat 1, and the rounded corner plate 7 is fixedly connected to the output end of the telescopic cylinder 6. The rounded corner plate 7 is slidably connected to the connecting thick plate 2.

[0027] like Figure 5 and Figure 6As shown, the simple disassembly and assembly mechanism includes a short thick plate 8, a moving rod 9, a rotating shaft 10, a small motor 1001 and a connecting rod 11. The short thick plate 8 is fixedly connected to the bottom of the rounded plate 7, and the small motor 1001 is fixedly connected to the front and rear sides of the short thick plate 8. The output end of the small motor 1001 is fixedly connected to the rotating shaft 10. The front and rear sides of the short thick plate 8 are slidably connected to the moving rods 9 that are symmetrically distributed on the left and right. The moving rods 9 are rotatably connected to the connecting rods 11. The connecting rods 11 are fixedly connected to the adjacent rotating shaft 10, and the moving rods 9 are slidably connected to the connecting thick plate 2.

[0028] When people need to drive an excavator to dig trenches on the ground, they can pass the threaded rod at the top of the connecting thick plate 2 through the round hole of the connecting seat 1 on the excavator, and then fix the connecting thick plate 2 to the bottom of the connecting seat 1 by installing and rotating the threaded cap 5, so as to install the rotating head 3 on the excavator, and then start the large motor 4 to drive the rotating head 3 to rotate and dig trenches. This connection method is relatively simple but requires manual labor and is relatively inconvenient. Therefore, the threaded rod at the top of the telescopic cylinder 6 can be passed through the round hole of the connecting seat 1 first, and then the telescopic cylinder 6 can be fixed to the bottom of the connecting seat 1 by installing and rotating the threaded cap 5, and then the threaded rod at the top of the connecting thick plate 2 can be passed through the hole opened on the rounded plate 7. The round holes are aligned, and then the small motor 1001 is started to drive the rotating shaft 10 to rotate, and the paired moving rods 9 are driven to move backwards through the connecting rods 11. The paired moving rods 9 move backwards and enter the square holes on the left and right sides of the connecting thick plate 2, so that the connecting thick plate 2 is fixedly connected to the bottom of the rounded plate 7. When people need to replace the connecting thick plate 2 and the rotating head 3, the small motor 1001 can be started to drive the rotating shaft 10 to rotate, and the paired moving rods 9 are driven to move toward each other and restore to their original positions through the connecting rods 11. The connecting thick plate 2 will then fall off from the bottom of the rounded plate 7, and then the rounded plate 7 can be aligned with the connecting thick plate 2 at the top of the other rotating head 3 and the motor can be started to complete the disassembly and installation.

[0029] Example 2

[0030] On the basis of Example 1, Figure 7 As shown, it also includes a perforated plate 12, a rotating block 13, a long arc plate 1301, a short arc plate 1302, a round head plate 1303, a first return spring 14 and a second return spring 15. The front side of the short thick plate 8 is fixedly connected to the perforated plate 12, and the front side of the perforated plate 12 is rotatably connected to the rotating block 13. The left and right sides of the perforated plate 12 are fixedly connected to the round head plate 1303, and the front side of the round head plate 1303 is slidably connected to the short arc plate 1302. A pair of first return springs 14 are fixedly connected between the short arc plate 1302 and the round head plate 1303. The left and right sides of the perforated plate 12 are slidably connected to the long arc plate 1301, and a pair of second return springs 15 are fixedly connected between the long arc plate 1301 and the perforated plate 12. The short arc plate 1302 and the long arc plate 1301 are both in contact with the rotating block 13.

[0031] like Figure 7As shown, the cross-sections of the left and right ends of the rotating block 13 are regular octagons.

[0032] like Figure 7 As shown, a camera is provided at the bottom end of the rotating block 13 for observing the ditching situation.

[0033] When the trenching is deep, the mechanical arm of the excavator is not long enough, and the driver cannot see the trenching situation clearly, the rotating block 13 can be rotated according to the actual situation. Due to the octagonal structure of the rotating block 13, the rotating block 13 will first squeeze the long arc plate 1301 and the short arc plate 1302 when it rotates, so that the long arc plate 1301 and the short arc plate 1302 on the same side move back to back, and the first return spring 14 is immediately stretched, and the second return spring 15 is immediately compressed. When the rotating block 13 is rotated to a suitable angle, the long arc plate 1301 and the short arc plate 1302 move toward each other under the reset action of the second return spring 15 and the first return spring 14 respectively, so as to tighten and fix the rotating block 13, and the telescopic cylinder 6 can also be started to adjust the overall length of the trench opener according to the actual situation.
