Description

Technical Field

[0001] The utility model belongs to the technical field of amphibious working tool design, in particular to a lifting and raising roof collecting rake for an amphibious working vehicle. Background Art

[0002] With the development of my country's economy, the requirements for water environment management are getting higher and higher. In particular, traditional excavators cannot enter the water for coastal tidal flat management, sea reclamation projects and saline-alkali land transformation, excavation and dredging, etc., so a large number of amphibious excavators or working vehicles have emerged.

[0003] Existing amphibious excavators or working vehicles mostly use collecting rakes to clean up the river. After collecting, the floating garbage is piled up in the gentler part of the nearby river bank. The amphibious vehicle needs to go on and off the shore frequently, or the collecting boat is followed by the amphibious vehicle during the cleaning process, and the salvaged garbage is directly dumped on the collecting boat. The above process has the following technical problems:

[0004] When the working vehicle is working on a river channel with high embankments and narrow river surfaces, the collection boat cannot follow effectively. At this time, the amphibious vehicle needs to repeatedly go up and down the shore to clean up the garbage accumulated in the collection rake. Since the working vehicle can only go up and down the gentle slope, a lot of time will be wasted on the return journey in actual work, which seriously affects its work efficiency.

[0005] How to design a new collecting rake to solve the above-mentioned technical problems has long puzzled technical personnel in this field. Utility Model Content

[0006] In view of the above technical problems, the utility model provides a lifting and elevated collecting rake for an amphibious work vehicle. By adding a lifting and flipping mechanism, the operating height and operating range of the collecting rake can be greatly improved, so that the amphibious work vehicle can efficiently carry out floating cleaning operations in rivers with higher embankments and reduce the number of times of going ashore.

[0007] The utility model solves the above problems through the following technical means:

In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, the lifting and elevated collecting rake for the amphibious work vehicle is installed on the amphibious work vehicle 1 and includes a lifting mechanism 2, a turning mechanism 3 and a collecting rake 4. In the figure, the bottom of the lifting mechanism 2 is installed on the amphibious work vehicle 1, and the top of the lifting mechanism 2 is installed with the turning mechanism 3, and the lifting mechanism 2 is used to adjust the height and position of the turning mechanism 3; the top of the turning mechanism 3 is installed with the collecting rake 4, and the turning mechanism 3 is used to drive the collecting rake 4 to turn over and dump.

[0024] In actual work, this solution can greatly increase the operating height and operating range of the collecting rake by adding lifting and flipping mechanisms, so that the amphibious operation vehicle can efficiently carry out floating cleaning operations in rivers with higher embankments and reduce the number of times it goes ashore.

[0025] In the figure, the collecting rake 4 is in the shape of a bucket as a whole, and the bottom and side surfaces of the collecting rake 4 are porous collecting mesh plates 401. A shovel plate 402 is installed at the front end of the collecting rake 4, and baffles 403 are installed on both sides of the collecting rake 4. The bottom center position of the collecting rake 4 protrudes inward to form an axis connection cavity 404, and the interior of the axis connection cavity 404 is installed with a bottom axis seat 405 for connecting the flipping mechanism 3.

[0026] In actual operation, the collection rake adopts a mesh plate structure, which can quickly collect various small floating objects on the water surface. At the same time, the left and right side plates are added to increase the collection volume, thereby improving the floating cleaning efficiency.

[0027] In the figure, the flipping mechanism 3 includes a flipping cylinder 301, a flipping bracket 302, a flipping shaft 303 and a flipping sleeve 304. The cylinder tail of the flipping cylinder 301 is installed in the top rotating shaft seat of the lifting mechanism 2 through a rotating shaft, and the cylinder head of the flipping cylinder 301 is installed in the bottom shaft seat 405 through a rotating shaft. The bottoms of multiple flipping brackets 302 are fixed on the top of the lifting mechanism 2. A flipping sleeve 304 is vertically arranged on the top of the flipping bracket 302. The flipping sleeve 304 can be rotatably mounted on the flipping shaft 303, and the flipping shaft 303 is fixed at the bottom front end position of the collecting rake 4.

[0028] During actual operation, since the bottoms of the flip cylinder 301 and the flip bracket 302 are both installed on the lifting connecting frame 207, when the flip cylinder 301 is extended, the collecting rake 4 will be lifted around the flip axis 303 at the bottom front end to complete the garbage dumping action. When the flip cylinder 301 is contracted, the collecting rake 4 will be lowered around the flip axis 303 at the bottom front end to be retracted. The angle of the collecting rake 4 can be adjusted by the extension and contraction amount of the flip cylinder 301.

[0029] In the figure, the lifting mechanism 2 includes a fixed seat 201, a first lifting cylinder 202, a lifting arm 203, a second lifting cylinder 204, an arc rocker arm 205, a lifting connecting rod 206 and a lifting connecting frame 207, wherein: the back of the fixed seat 201 is fixedly connected to the amphibious working vehicle 1; the rear end of the first lifting cylinder 202 is hinged in the top fixing hole of the fixed seat 201 through a rotating shaft, and the front end of the first lifting cylinder 202 is hinged to the rear connecting hole of the lifting connecting rod 206 through a rotating shaft; the rear bearing hole of the lifting arm 203 is hinged in the middle fixing hole of the fixed seat 201 through a rotating shaft, and the front bearing hole of the lifting arm 203 is connected to the middle fixing hole of the fixed seat 201 through a rotating shaft. The lifting connecting frame 207 is hinged through the rotating shaft; the rear end of the second lifting cylinder 204 is hinged in the bottom fixing hole of the fixing seat 201 through the rotating shaft, and the front end of the second lifting cylinder 204 is hinged in the hinge seat of the lifting arm 203 through the rotating shaft; the top rocker arm hole of the arc rocker arm 205 is hinged to the front end of the first lifting cylinder 202 and the rear connecting hole of the lifting connecting rod 206 through the rotating shaft, and the bottom rocker arm hole of the arc rocker arm 205 is hinged to the transmission hole at the front end of the lifting arm 203 through the rotating shaft; the front connecting hole of the lifting connecting rod 206 is hinged to the lifting connecting frame 207 through the rotating shaft; the lifting connecting frame 207 is used to install the flip mechanism 3.

[0030] In actual work, the distance between the top rocker arm hole and the bottom rocker arm hole is consistent with the distance between the top fixing hole and the middle fixing hole. The distance between the top rocker arm hole and the bottom rocker arm hole is consistent with the distance between the top fixing hole and the middle fixing hole. When the overall length of the tilting cylinder is consistent with the distance between the transmission hole and the rear bearing hole, a parallelogram structure is formed between the tilting cylinder, the lifting arm, the arc rocker arm and the fixing seat. At this time, no matter how the lifting cylinder works, the connecting frame always maintains the same angle.

[0031] It should be noted that the lifting structure adds an arc-shaped rocker arm and a connecting rod structure to the traditional mechanical arm structure, and optimizes the distance between each hinge point, which significantly improves the unloading height, unloading distance, boom lifting force and controllable translation of the device. In particular, after the flip cylinder is fixed, the horizontal angle of the connecting frame and the corresponding working auxiliary tool can always be kept unchanged during the working process of the lifting cylinder.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
