Description

Technical Field

[0001] The utility model relates to a transfer bucket for sand and gravel feeding. Background Art

[0002] During the construction of the lower floors, the bricks, sand and gravel used need to be transferred little by little from the ground to the corresponding floors by workers through a simple crane. Taking self-built houses in rural areas as an example, they are even transferred to the corresponding floors by manual carrying.

[0003] Although the simple cranes commonly used at present can quickly lift and transfer construction materials, the loading bucket does not have a material outlet at the bottom. Therefore, after the materials are lifted to the upper floor, they need to be manually pushed to tilt the bucket to unload the materials. However, the bucket is too heavy and easily shakes and collides with walls or workers, which is unsafe and inconvenient to unload. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a transfer bucket for sand and gravel feeding.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A transfer bucket for loading sand and gravel comprises a bucket body, a bottom cover mounted below the bucket body and hingedly mounted to the bucket body, a first connecting arm and a second connecting arm arranged on both sides of the bucket body for connecting the bucket body and the bottom cover, one end of the bucket body being hingedly mounted and the other end of the bucket body being hingedly mounted and the second connecting arm on a hydraulic telescopic cylinder, the first connecting arm and the second connecting arm being arranged in a V shape, the ends of the first connecting arm and the second connecting arm being hingedly mounted at the center of both sides of the bottom cover at the same time, the lower end of the hydraulic telescopic cylinder being hingedly mounted at the lower end of the second connecting arm, and the hydraulic telescopic cylinder being parallel to the first connecting arm.

[0007] Preferably, a bottom cover hinge seat, a first connecting arm hinge seat, a second connecting arm hinge seat and a hydraulic telescopic cylinder hinge seat are welded on both sides of the bucket body.

[0008] Preferably, connecting rods are mounted on both sides of one end of the bottom cover.

[0009] Preferably, hinged holes are provided at the center of both sides of the bottom cover.

[0010] Preferably, the upper end of the first connecting arm is bent, and an auxiliary arm is hinged at the bent portion of the first connecting arm.

[0011] Preferably, the lower end of the first connecting arm is integrally formed with an assembly head with fixed shafts at both ends.

[0012] Preferably, a hydraulic telescopic cylinder assembly hole is provided at the lower end of the second connecting arm corresponding to the position where the hydraulic telescopic cylinder is installed.

[0013] The beneficial effects of the utility model are as follows: the first connecting arm and the second connecting arm driven by the hydraulic telescopic cylinder can accurately control the opening and closing of the bottom cover, so as to accurately control the discharge of sand and gravel when needed to avoid excessive or insufficient discharge; the first connecting arm, the second connecting arm, the bottom cover and the hydraulic telescopic cylinder are reasonably installed to ensure the stability and reliability of the structure, and can be used in a high-intensity working environment. Therefore, during the sand and gravel feeding process, the bottom cover can fit tightly to the bottom of the bucket body to prevent the sand and gravel from rushing open the bottom cover, thereby ensuring the safety and stability of the operation and reducing the possibility of accidents.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0019] Example

[0020] like Figure 1-4 As shown, a transfer bucket for sand and gravel loading includes a bucket body 1, a bottom cover 2 assembled under the bucket body 1 and hingedly mounted with the bucket body 1, a first connecting arm 3 and a second connecting arm 4 arranged on both sides of the bucket body 1 for connecting the bucket body 1 and the bottom cover 2, a hydraulic telescopic cylinder 5 with one end hingedly mounted with the bucket body 1 and the other end hingedly mounted with the second connecting arm 4, the first connecting arm 3 and the second connecting arm 4 being arranged in a V shape, the ends of the first connecting arm 3 and the second connecting arm 4 being hingedly mounted at the center parts of both sides of the bottom cover 2 at the same time, the lower end of the hydraulic telescopic cylinder 5 being hingedly mounted at the lower end part of the second connecting arm 4, and the hydraulic telescopic cylinder 5 being parallel to the first connecting arm 3.

[0021] A bottom cover hinge seat 11 , a first connecting arm hinge seat 12 , a second connecting arm hinge seat 13 and a hydraulic telescopic cylinder hinge seat 14 are welded on both sides of the bucket body 1 .

[0022] The bottom cover 2 is provided with connecting rods 21 on both sides of one end. Specifically, the lower end of the connecting rod 21 is hingedly mounted on the bottom cover 2, and the other end is hingedly mounted on the bottom cover hinge seat 11. When the bottom cover 2 is active, it is convenient for the bottom cover 2 to be connected through the connecting rod 21 and deformed and opened from the bottom of the bucket body 1. The central part of both sides of the bottom cover 2 is provided with hinge holes 22, which facilitate the first connecting arm 3 and the second connecting arm 4 to be simultaneously assembled in the hinge holes 22 through the hinge shaft. The second connecting arm 4 is pushed by the hydraulic telescopic cylinder 5, which can simultaneously link the first connecting arm 3 to open the bottom cover 2 for unloading.

[0023] It should be further explained that the first connecting arm 3 and the second connecting arm 4 are arranged in a V shape and assembled with the bottom cover 2. When the hydraulic telescopic cylinder 5 contracts, the first connecting arm 3 and the second connecting arm 4 can be used to pull the bottom cover 2 tightly to the bottom of the bucket body 1 to prevent sand and gravel from breaking the bottom cover 2.

[0024] The upper end of the first connecting arm 3 is bent, and an auxiliary arm 31 is hinged at the bent portion of the first connecting arm 3. Specifically, the auxiliary arm 31 is installed in conjunction with the first connecting arm hinge seat 12. Specifically, the cooperation of the auxiliary arm 31 is more conducive to the flexible deformation of the first connecting arm 3 in the linkage with the second connecting arm 4, thereby controlling the opening or closing of the bottom cover 2.

[0025] The lower end of the first connecting arm 3 is integrally formed with an assembly head 32 with fixed shafts at both ends. Specifically, the first connecting arm 3 is inserted into the hinge hole 22 of the bottom cover 1 through the fixed shaft on one side of the assembly head 32, and the fixed shaft on one side of the assembly head 32 cooperates with the second connecting arm 4 for assembly.

[0026] A hydraulic telescopic cylinder assembly hole 41 is provided at the lower end of the second connecting arm 4 corresponding to the location where the hydraulic telescopic cylinder 5 is installed. Specifically, it is convenient for the output end of the hydraulic telescopic cylinder 5 to be hingedly installed with the hydraulic telescopic cylinder assembly hole 41, thereby driving the second connecting arm 4 to complete the opening or closing of the bottom cover 2.

[0027] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
