Description

Technical Field

[0001] The utility model relates to the technical field of sugarcane knife auxiliary devices, in particular to a sugarcane knife with replaceable blade for easy use. Background Technique

[0002] Sugarcane is a temperate and tropical crop. Sugarcane is rich in sugar, water, and various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to the human body's metabolism. Sugarcane is the raw material for making sucrose.

[0003] The blade part of the existing sugarcane knife adopts a fixed structure design. The blade is embedded in the knife holder at the time of leaving the factory. When the blade fails, the whole sugarcane knife cannot be used continuously, and the whole sugarcane knife needs to be replaced, resulting in the problem of increased cost. Therefore, it is particularly important to design a safety protection type sugarcane knife to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the blade part of the existing sugarcane knife adopts a fixed structure design. The blade is embedded in the knife holder at the time of leaving the factory. When the blade fails, the whole sugarcane knife cannot be used continuously, and the whole sugarcane knife needs to be replaced, resulting in the problem of increased cost, and a sugarcane knife with replaceable blade for easy use is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a sugarcane knife with replaceable blade for easy use, including a knife holder, a handle is fixedly connected to the right end of the knife holder, a bracket is rotatably connected to the knife holder through a rotating shaft, the hinge rotation point is located at the left end of the bracket, the right end of the bracket is movably connected to the knife holder, a receiving groove is arranged on the knife holder, the bracket is detachably connected to the receiving groove through a bolt, a frame is slidably connected to the bracket, and a blade is fixedly connected to the frame.

[0006] Preferably, a slider is fixedly connected to the bottom of the frame, the slider is slidably arranged on the bracket, and the cross section of the blade is wedge-shaped.

[0007] Preferably, the cross section of the slider is wedge-shaped, and the slider and the frame are connected by multiple groups of fasteners.

[0008] Preferably, an anti-slip sleeve is fixedly connected to the handle.

[0009] Compared with the prior art, the advantages and positive effects of the utility model are as follows

[0010] 1. In the present utility model, during use, a support structure is rotatably connected to a tool rest by means of a rotating shaft. A frame is slidably arranged in the support, and a blade structure is fixedly connected to the frame. Finally, the frame is fixedly connected to the support by means of a fastener. Compared with the conventional structure in which the blade is embedded in the tool rest, the structure adopted by the present utility model enables the rapid disassembly and replacement of the blade, improves the overall efficiency of blade replacement, avoids the clamping design, and prevents the situation where the entire sugarcane knife needs to be replaced directly when the blade is damaged, reducing the production and processing costs. The overall structure is compact, which is easy for the staff to install and maintain, and solves the problem of the fixed structure design of the blade part of the existing sugarcane knife, where the blade is embedded in the tool rest at the factory. When the blade fails, the entire sugarcane knife cannot be used continuously and needs to be replaced as a whole, resulting in increased costs.

[0011] 2. In the present utility model, during use, by installing an anti-slip sleeve structure on the handle, it ensures a good grip for the staff during later use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0017] The present utility model provides a sugarcane knife with a replaceable blade for convenience, which includes a knife holder 1. A handle 2 is fixedly connected to the right end of the knife holder 1. A bracket 301 is rotatably connected to the knife holder 1 through a rotating shaft 3. The hinge rotation point is located at the left end of the bracket 301. The right end of the bracket 301 is movably connected to the knife holder 1. A receiving groove 4 is provided on the knife holder 1. The bracket 301 is detachably connected to the receiving groove 4 through a bolt 401. A frame 5 is slidably connected to the bracket 301. A blade 501 is fixedly connected to the frame 5. A slider 502 is fixedly connected to the bottom of the frame 5. The slider 502 is slidably arranged on the bracket 301 to play a guiding role for the frame 5 to slide into the bracket 301. The cross-section of the blade 501 is wedge-shaped.

[0018] When the sugarcane knife with a replaceable blade 501 for convenience is actually used and the blade 501 needs to be replaced, the staff manually loosens the bolt 401, and then rotates around the rotating shaft 3 at the left end of the bracket 301, so that the bracket 301 moves away from the knife holder 1 until the bracket 301 completely moves out of the position of the knife holder 1. Then the staff manually removes the fastener 6, and then manually operates the frame 5 to slide out of the bracket 301. The slider 502 on the frame 5 slides on the bracket 301 to play a guiding role. Then replace the frame 5 equipped with a new blade 501 and slide it into the bracket 301 again. Then screw in the fastener 6 to install the newly replaced frame 5 into the bracket 301, completing the replacement work of the new blade 501. Then reset the bracket 301 equipped with the new blade 501 into the receiving groove 4, and finally fix and limit it in the receiving groove 4 by the bolt 401. By means of the structure that the bracket 301 is rotatably connected to the knife holder 1 through the rotating shaft 3 in the knife holder 1, and the frame 5 is slidably arranged in the bracket 301, and the blade 501 is fixedly connected to the frame 5, and finally the frame 5 is fixedly connected to the bracket 301 by the fastener 6. Compared with the conventional structure of embedding the blade 501 in the knife holder 1, the structure adopted by the present utility model completes the quick disassembly and replacement of the blade 501, improves the overall efficiency of replacing the blade 501, avoids the stuck-in design, and the situation of directly replacing the whole new sugarcane knife once the blade 501 is damaged, reduces the production and processing cost, and the overall structure is compact, which is easy for the staff to install and maintain.

[0019] As Figure 1-2 shown, the cross-section of the slider 502 is wedge-shaped. The slider 502 and the frame 5 are connected by multiple groups of fasteners 6. An anti-slip sleeve 7 is fixedly connected to the handle 2.

[0020] The effect achieved by the entire embodiment 1 is that during use, by installing the anti-slip sleeve 7 structure on the handle 2, it ensures that the staff has a good grip during later use.

[0021] Working principle: When the cutting edge needs to be replaced, the staff manually loosens the bolt, and then rotates around the rotating shaft at the left end of the bracket, so that the bracket moves away from the tool rest until the bracket completely moves out of the tool rest position. Then the staff manually removes the fastener, and then manually operates the frame to slide out of the bracket. The slider on the frame slides on the bracket to play a guiding role. Then replace the frame with a new cutting edge and slide it into the bracket again. Then screw in the fastener to install the newly replaced frame into the bracket, completing the replacement of the new cutting edge. Then reset the bracket with the new cutting edge into the receiving groove, and finally fix and limit it in the receiving groove with bolts.
