DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-3As shown, the utility model proposes a variable bucket capacity device for a loader, including a bucket 1, a first blocking component 2 for blocking is arranged at the bottom inner wall of the bucket 1, the first blocking component 2 includes a first baffle 21, the first baffle 21 is arranged in the bucket 1, and is used to block the material shoveled into the bucket 1; a plurality of springs 22 are arranged in an array in an active cavity opened inside the first baffle 21, and the bottom ends of the plurality of springs 22 are fixedly connected to the bottom wall of the active cavity, which provides convenience for subsequent blocking work.

[0021] Furthermore, a second blocking component 3 which also plays a blocking role is provided at the top of the first blocking component 2. The second blocking component 3 includes a second baffle plate 31. The bottom of the second baffle plate 31 passes through a movable opening opened at the top of the first baffle plate 21 and is arranged in an movable cavity opened in the first baffle plate 21. At the same time, the bottom of the second baffle plate 31 is also fixedly connected to the tops of multiple springs 22. The second baffle plate 31 is positioned by multiple springs 22, which is conducive to the movement of the second baffle plate 31; an anti-slip plate 32 is fixedly installed on the bottom of the second baffle plate 31, and the anti-slip plate 32 is arranged in the movable cavity. The size of the anti-slip plate 32 is larger than the movable opening. The anti-slip plate 32 is restricted by the second baffle plate 31 to prevent the anti-slip plate 32 from escaping from the movable cavity; two convex shafts 33 are symmetrically arranged on the two side walls of the second baffle plate 31, and the opposite ends of the two convex shafts 33 are respectively fixedly connected to the two side walls of the second baffle plate 31, and are arranged above the first baffle plate 21.

[0022] Furthermore, a first electric push rod 4 and a second electric push rod 5 are symmetrically installed on one side wall of the bucket 1, and both the first electric push rod 4 and the second electric push rod 5 are fixedly installed on one side wall of the bucket 1; movable shafts are symmetrically welded on both side walls of the first baffle 21, and the movable shafts are not shown in the figure.

[0023] Furthermore, guide limit assemblies 6 for assisting the sliding of the first blocking assembly 2 and the second blocking assembly 3 are arranged on the front-facing wall and the back wall of the first blocking assembly 2 and the second blocking assembly 3. The multiple groups of guide limit assemblies 6 are evenly divided into two groups, each group includes two guide limit assemblies 6, and the two groups of guide limit assemblies 6 are symmetrically arranged on both sides of the first baffle plate 21 and the second baffle plate 31, respectively, and are also arranged in the first slide groove opened on the opposite surface of the inner wall of the bucket 1; the guide limit assembly 6 includes a movable block 61, the movable block 61 is arranged in the first slide groove corresponding to the position, and the movable block 61 is assisted to slide by the first slide groove; two guide slide bars 62 are symmetrically welded at the top and bottom of the movable block 61, and the second slide grooves are symmetrically opened at the top and bottom of the first slide groove, and the two guide slide bars 62 are respectively arranged in the second slide groove corresponding to the position, and are assisted to slide by the first slide groove. The two slide grooves cooperate with the guide slide bar 62 to prevent the movable block 61 from detaching from the first slide groove and affecting the subsequent position adjustment of the first blocking component 2 and the second blocking component 3; multiple perforations are connected to multiple first slide grooves, and the output ends of the first electric push rod 4 and the second electric push rod 5 respectively pass through the perforations corresponding to the positions and are fixedly connected to the back of the movable block 61 corresponding to the positions, so as to facilitate the movement of the movable block 61; a rotating groove is opened on the side wall of the movable block 61, and the bearing 63 is arranged in the rotating groove.

The bearing 63 assists the rotation of the movable shaft and the convex shaft 33 to avoid the second baffle 31 and the first baffle 21 moving to different positions, which affects the blocking effect.

[0024] In this embodiment, when it is necessary to control the amount of the bucket 1, the first electric push rod 4 and the second electric push rod 5 are started to push the movable block 61 to move in the first chute, and with the assistance of the movable shaft and the convex shaft 33, the position of the first baffle 21 and the second baffle 31 is adjusted, so as to achieve the purpose of controlling the amount of the bucket 1, which is conducive to controlling the amount of the bucket 1 in a desired state and avoiding overweight in the process of shoveling materials. In order to avoid the material falling from the bucket 1 during the flat shoveling process, the first electric push rod 4 is used to shorten the movable position of the first baffle 21. The second baffle plate 31 is pushed to move by the second electric push rod 5, so that the activity path of the second baffle plate 31 is longer than that of the first baffle plate 21, thereby reducing the risk of falling after shoveling materials. When the positions of the first baffle plate 21 and the second baffle plate 31 are different, the second baffle plate 31 can be extended or shortened during the tilting process through the setting of the spring 22, so as to avoid hindering the position adjustment of the two. At the same time, with the setting of multiple sets of guide limit assemblies 6, the problem of the difficulty in tilting the second blocking assembly 3 and the first blocking assembly 2 is solved, thereby further facilitating the capacity adjustment.
