Specific Embodiment

[0018] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0019] Refer to Figures 1-4 : A bucket connection driving structure of a crawler bulldozer, including a bulldozer main body 101, a mounting frame 103 is provided on the bulldozer main body 101, a first driving mechanism 200 and a second driving mechanism 300 are provided on the mounting frame 103, a connecting seat 104 is provided at one end of the first driving mechanism 200 and the second driving mechanism 300 away from the mounting frame 103, a bucket 102 is provided on the connecting seat 104, a clamping seat 105 is provided on the bucket 102, and the connecting seat 104 and the clamping seat 105 are clamped through a docking mechanism 500; the docking mechanism 500 includes a clamping block 501, a return spring 502, an unlocking rope 503, a docking block 504, a guiding groove 505 and a clamping groove 506, several guiding grooves 505 are provided on the clamping seat 105, several docking blocks 504 matched with the guiding grooves 505 are provided on the connecting seat 104, clamping blocks 501 are symmetrically slidably arranged in the docking blocks 504, two ends of the return spring 502 are respectively connected to the side wall of the clamping block 501 and the inner wall of the docking block 504, one end of the unlocking rope 503 is connected to the clamping block 501, the other end of the unlocking rope 503 passes through the inner wall of the docking block 504 and the side wall of the connecting seat 104 and is connected to the unlocking mechanism 400, a clamping groove 506 matched with the clamping block 501 is provided in the guiding groove 505, and the clamping block 501 is made of high-strength steel.

[0020] The first driving mechanism 200 and the second driving mechanism 300 are used to adjust the digging depth and angle of the bucket 102, and the docking mechanism 500 is used to facilitate the quick installation of the bucket 102 on the bulldozer main body 101 and enable quick disassembly.

[0021] First, place the bucket 102 in place, and then correctly align the bucket 102 of the bulldozer main body 101 with the connecting components of the device. By operating the connecting seat 104 of the bulldozer main body 101 downward, the docking block 504 enters the guiding groove 505. Since the cross-section of the docking block 504 is a downward wedge shape, the docking block 504 can be inserted into the guiding groove 505. At this time, the clamping block 501 is forced to drive the return spring 502 to retract. When the clamping block 501 encounters the clamping groove 506, the return spring 502 drives the clamping block 501 to reset to complete the installation and fixation. Such a clamping block 501 is made of high-strength steel and can withstand high loads.

[0022] Refer to Figures 2-4 The unlocking mechanism 400 includes a limiting rod 401, a limiting block 402, an unlocking ring 403, a fixing ring 404, an unlocking rod 405, and a pulling block 406. The connecting seat 104 is provided with a limiting rod 401 through which the unlocking rope 503 passes. The connecting seat 104 is provided with a limiting block 402. The unlocking rope 503 passes through the limiting block 402 and is connected to the unlocking ring 403. A fixing ring 404 is provided on the side wall of the connecting seat 104. An unlocking rod 405 that cooperates with the unlocking ring 403 is slidably arranged in the fixing ring 404. A pulling block 406 is provided on the side wall of the unlocking rod 405.

[0023] When disassembly is required, pull the unlocking rope 503 and pull the pulling block 406 to drive the unlocking rod 405 to slide and put the unlocking ring 403 on the unlocking rope 503 on the side wall of the unlocking rod 405, so that the unlocking of the bucket 102 from the bulldozer main body 101 can be completed. In this way, one person can complete the replacement and installation without the assistance of others, improving work efficiency.

[0024] Refer to Figure 1 The first driving mechanism 200 includes a first hydraulic cylinder 201, a connecting arm 202, a boom 203, and a connecting column 204. The first hydraulic cylinder 201 is installed on the mounting frame 103. The output end of the first hydraulic cylinder 201 is provided with a connecting arm 202. The other end of the connecting arm 202 is connected to the boom 203. The other end of the boom 203 is rotatably matched with the connecting seat 104.

[0025] Start the first hydraulic cylinder 201 to drive the connecting arm 202 to move. The connecting arm 202 pushes against the boom 203 to move, and the digging depth of the bucket 102 can be adjusted.

[0026] Refer to Figure 1: The second driving mechanism 300 includes a second hydraulic cylinder 301, a support arm 302, a first moving arm 303 and a second moving arm 304. The second hydraulic cylinder 301 is installed on the mounting frame 103. The output end of the support arm 302 is connected to the support arm 302. The other end of the support arm 302 is rotatably engaged with the first moving arm 303, driving the other end of the first moving arm 303 to be rotatably engaged with the second moving arm 304. The other end of the second moving arm 304 is rotatably engaged with the connecting seat 104.

[0027] Start the second hydraulic cylinder 301 to drive the support arm 302 to move. The support arm 302 pushes against the first moving arm 303 and the second moving arm 304 to move, so as to adjust the angle of the bucket 102.

[0028] Working principle: First, place the bucket 102 in place, and then correctly align the bucket 102 of the bulldozer main body 101 with the connecting components of this equipment. By operating the connecting seat 104 of the bulldozer main body 101 downward, the docking block 504 enters the guiding groove 505. Since the cross-section of the docking block 504 is a downward wedge shape, the docking block 504 can be inserted into the guiding groove 505. At this time, the clamping block 501 is stressed to drive the return spring 502 to retract. When the clamping block 501 encounters the clamping groove 506, the return spring 502 drives the clamping block 501 to reset to complete the installation and fixation. Such a clamping block 501 is made of high-strength steel and can withstand high loads. When disassembly is required, pull the unlocking rope 503 and pull the pulling block 406 to drive the unlocking rod 405 to slide, and put the unlocking ring 403 on the unlocking rope 503 on the side wall of the unlocking rod 405, so that the unlocking of the bucket 102 and the bulldozer main body 101 can be completed. In this way, one person can complete the replacement and installation without the assistance of others, improving work efficiency; by starting the first hydraulic cylinder 201 to drive the connecting arm 202 to move, the connecting arm 202 pushes against the bucket rod 203 to move, so as to adjust the digging depth of the bucket 102. Start the second hydraulic cylinder 301 to drive the support arm 302 to move. The support arm 302 pushes against the first moving arm 303 and the second moving arm 304 to move, so as to adjust the angle of the bucket 102.

[0029] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
