Description

Technical Field

[0001] This utility model relates to the field of cement fly ash, specifically to a bag-breaking tool. Background Technology

[0002] Existing cement fly ash bag-breaking tools have problems such as poor bag-breaking effect and inability to handle obstacles. Utility Model Content

[0003] The purpose of this invention is to provide a drag-and-drop rotary blade to solve the above-mentioned technical problems.

[0004] A drag-and-drop rotary cutter includes a rotary cutter, which includes a cutter holder. A first rotating shaft is rotatably connected to the cutter holder, and a rotationally symmetrical cutter is fitted at the front end of the first rotating shaft. The drag-and-drop rotary cutter also includes a long, narrow guide plate. A long, narrow fixed rack is provided on the front side wall of the guide plate. A sliding frame is fitted on the guide plate, and the sliding frame includes a front panel. The cutter holder is fixed on the front panel. A driven gear is fitted at the end of the first rotating shaft, and the driven gear meshes with the fixed rack.

[0005] Preferably, the cutting tool includes a first part and a second part, the included angle between the first part and the second part is an obtuse angle, and both the first part and the second part are provided with cutting edges, which are located on the same side.

[0006] Preferably, the sliding frame further includes a rear panel, and the four corners of the front panel and the rear panel are respectively connected by four second pivots.

[0007] Preferably, a guide wheel is fitted onto the second rotating shaft, and the guide wheel engages with the guide rail plate.

[0008] Preferably, it also includes a dragging mechanism for driving the sliding frame to move on the guide rail plate.

[0009] Preferably, the dragging mechanism includes a drive sprocket, a driven sprocket, and a drag chain. The drive sprocket is fixed to the left end of the guide plate, the driven sprocket is fixed to the right end of the guide plate, and the drag chain is tensioned on the drive sprocket and the driven sprocket. The drag chain passes through the sliding frame and is fixedly connected to the rear panel.

[0010] Preferably, the length of the fixed rack is less than the distance between the driving sprocket and the driven sprocket.

[0011] Preferably, it also includes a drive motor, which drives the drive sprocket.

[0012] Beneficial effects: First, the rotating blade of this invention can rotate automatically to break the bag, greatly improving the efficiency compared to manual bag breaking. Second, the rotating blade breaks the bag by rotating, which can change the breaking angle and avoid obstacles, thus reducing their impact. Finally, the rotating blade rotates as the sliding frame moves left and right, allowing the breaking position to be changed by the left and right movement of the sliding frame, further reducing the impact of obstacles.

[0014] Figure 2 for Figure 1 Top view of the structure. Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] Reference Figure 1 and Figure 2 A drag-type rotary cutter includes a rotary cutter 9, which includes a cutter holder 7. A first rotating shaft is rotatably connected to the cutter holder 7, and a rotationally symmetrical cutter is fitted onto the front end of the first rotating shaft. Preferably, the cutter includes a first part and a second part, with an obtuse angle between the first part and the second part. Both the first part and the second part are provided with cutting edges, which are located on the same side. On the one hand, this increases the overall length of the cutting edge, which is beneficial for improving bag-breaking efficiency. On the other hand, the cutting angle can be changed by utilizing the change in the cutting edge angle, reducing the influence of obstacles on the bag-breaking angle.

[0017] The drag-type rotary cutter also includes a long, narrow guide plate 1, with a long, narrow fixed rack 5 on its front side wall. A sliding frame 8 is fitted onto the guide plate 1, and the sliding frame 8 includes a front panel, a cutter holder 7 fixed to the front panel, and a driven gear 6 fitted at the end of a first rotating shaft, which meshes with the fixed rack 5. The sliding frame 8 also includes a rear panel, and the four corners of the front and rear panels are connected by four second rotating shafts. This alleviates the deformation of the guide plate 1 caused by uneven force distribution when only the front panel is present. Simultaneously, the rear panel also prevents the sliding frame 8 from detaching from the guide plate 1. A guide wheel is fitted onto the second rotating shaft, and the guide wheel engages with the guide plate 1. This guide wheel provides guidance, reducing the wobbling of the sliding frame 8 during sliding. Preferably, the fixed rack 5 is located at the lower part of the guide plate 1; more preferably, the bottom surface of the fixed rack 5 is flush with the bottom surface of the guide plate 1.

[0018] The drag-type rotary cutter also includes a dragging mechanism that drives the sliding frame 8 to move on the guide rail plate 1. The dragging mechanism includes a drive sprocket 2, a driven sprocket 4, and a drag chain 3. The drive sprocket 2 is fixed to the left end of the guide rail plate 1, the driven sprocket 4 is fixed to the right end of the guide rail plate 1, and the drag chain 3 is tensioned on the drive sprocket 2 and the driven sprocket 4. The drag chain 3 passes through the sliding frame 8 and is fixedly connected to the rear panel. Preferably, the upper portion of the drag chain 3 is connected to the rear panel, while the lower portion is not connected. Compared to a structure where the lower portion is connected to the rear panel, this effectively improves the stability of the sliding frame 8's movement. Alternatively, the drag chain 3 can be adhesively connected to the rear panel. Alternatively, a limiting protrusion can be provided on the rear panel, and the limiting protrusion can be inserted into the drag chain 3.

[0019] Preferably, the length of the fixed rack 5 is less than the distance between the driving sprocket 2 and the driven sprocket 4. The left end of the fixed rack 5 is a certain distance from the driving sprocket 2, and the right end of the fixed rack 5 is a certain distance from the driven sprocket 4.

[0020] The drag-type rotary cutter also includes a drive motor, which drives the drive sprocket 2. This drives the drive sprocket 2 to rotate, and as the drive sprocket 2 rotates, the drag chain 3 causes the sliding frame 8 to move on the guide rail plate 1. The drive motor is preferably a reversible motor.

[0021] Preferably, the guide rail plate 1 is provided with a limiting plate; more preferably, each end of the fixed rack 5 is provided with a limiting plate. This limits the position of the sliding frame 8, preventing it from detaching from the fixed rack 5.

[0022] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
