Description

Technical Field

[0001] The utility model belongs to the field of wall breaking machine blades, in particular to a wall breaking machine blade. Background Art

[0002] The blade of a wall breaker is an important part of the wall breaker. The quality of its material and design directly affects the efficiency, lifespan and healthiness of the food. When choosing a wall breaker, the material and design of the blade are key considerations.

[0003] Traditional wall-breaking machine blades are mostly installed on the wall-breaking machine blade head through nuts. In order to prevent the nuts from loosening, the nuts are usually twisted very tightly. Therefore, it takes a lot of force to twist the nuts off during disassembly. When the wrench matching the nut is lost, the blade cannot be disassembled, and the installation and disassembly efficiency is low. In order to solve this problem, a wall-breaking machine blade that is easy to disassemble is disclosed in a Chinese patent with publication number CN216932866U. The cutter head is provided with two fixedly connected positioning posts, which pass through the first blade and are engaged with the second blade. The first blade and the second blade are both engaged with the cutter head. The second blade is abutted with a block, which is fixedly connected with a plurality of connecting posts, which are fixedly connected to a sliding post, and a card block is fixedly connected to the sliding post, which is engaged with a card slot. Then, when the first blade and the second blade need to be disassembled, the block is rotated, and the block drives the sliding post to rotate through a plurality of connecting posts, and the rotation of the sliding post drives the card block to move. When the card block rotates 180 degrees and then moves away from the second blade, the block is pulled to remove the sliding post and the card block from the inside of the cutter head. After removal, the first blade and the second blade are removed from the cutter head, thereby realizing the rapid disassembly of the first blade and the second blade, and improving the efficiency of disassembly and installation of the first blade and the second blade.

[0004] However, under this installation method, there will be a certain protrusion at the bottom end of the blade. When the blade rotates, this protrusion will affect the crushing of objects because the protrusion will interfere between the blade and the object, affecting the crushing effect. Utility Model Content

[0005] The technical problem to be solved is: how to make the blade easy to disassemble and assemble without affecting the crushing effect.

[0006] Technical solution: The utility model provides a wall breaking machine blade, including a main component and a connecting component: the main component includes a rotating shaft and a blade, and there is no protruding structure at the center of the bottom end of the blade; the connecting component includes a locking hole opened at the bottom end of the rotating shaft and a locking column connected to the top end of the blade and adapted to the locking hole; in addition, a fixing mechanism for fixing the locking column and the rotating shaft together in the X-axis direction is also provided on the outer side of the rotating shaft.

[0007] Furthermore, the fixing mechanism includes two semicircular tubes with the same height as the locking column and the same inner diameter as the diameter of the rotating shaft, wherein the inner side of one of the semicircular tubes is symmetrically connected to a horizontal stud rod up and down, and the other semicircular tube, the rotating shaft and the locking column are all penetrated by connecting holes compatible with the stud rod. After the stud rod passes through these connecting holes, a nut located on the outside of the other semicircular tube is matched and connected on its outer peripheral side.

[0008] Furthermore, a gasket ring is provided between the nut and the corresponding semicircular tube and is sleeved on the outer peripheral side of the stud rod, and the gasket ring is an elastic ring.

[0009] Furthermore, the blade includes: a base layer: composed of tungsten carbide, used to improve the overall hardness; a toughness layer: located on the outer layer of the base layer, composed of high-speed steel or chromium-molybdenum alloy, used to improve the overall toughness; a coating: located on the outer layer of the toughness layer, formed by evenly coating ceramics, diamonds or cemented carbide, used to reduce friction and improve wear resistance.

[0010] Furthermore, the outer side of the coating layer may be covered with a protective layer, and the composition of the protective layer may be the same as that of the base layer.

[0011] Furthermore, a plurality of evenly distributed fine holes may be formed through the blade, and these fine holes are used to promote the circulation of liquid.

[0012] Technical effect: In the utility model, the engaging column and the engaging hole engage the blade and the rotating shaft in the Y-axis direction. After the two are engaged, the engaging column and the rotating shaft are fixed in the X-axis direction through the action of the fixing mechanism. In this way, on the one hand, the entire connection structure exists above the blade, and there is no protruding structure below to affect the crushing process. On the other hand, the connection between the blade and the rotating shaft is more stable through the connection in the X-axis and Y-axis directions. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0020] The wall breaking machine blade provided in this specific embodiment is as follows Figure 1 , Figure 2 and Figure 3 As shown, it includes a main body component and a connecting component, wherein, as Figure 4 As shown:

[0021] The main component includes a rotating shaft 1 and a blade 2, and there is no protruding structure at the bottom center of the blade 2. The blade 2 includes:

[0022] Base layer: Made of tungsten carbide to increase the overall hardness;

[0023] Toughness layer: located on the outer layer of the base layer, made of high-speed steel or chromium-molybdenum alloy, used to improve the overall toughness;

[0024] Coating: Located on the outer layer of the toughness layer, it is formed by evenly applying ceramic, diamond or hard alloy to reduce friction and improve wear resistance;

[0025] The protective layer is located on the outer layer of the coating layer and is used to protect the coating layer. The composition of the protective layer can be the same as that of the base layer.

[0026] The connecting member includes a snap-in hole 3 opened at the bottom end of the rotating shaft 1 and a snap-in column 4 connected to the top end of the blade 2 and adapted to the snap-in hole 3; in addition, a fixing mechanism 5 for fixing the snap-in column 4 and the rotating shaft 1 together in the X-axis direction is also provided on the outer side of the rotating shaft 1. The fixing mechanism 5 includes two semicircular tubes 501 of the same height as the snap-in column 4 and the same inner diameter as the rotating shaft 1, wherein a horizontal stud rod 502 is symmetrically connected to the inner side of one of the semicircular tubes 501, and a connecting hole 503 adapted to the stud rod 502 is penetrated and opened on the other semicircular tube 501, the rotating shaft 1, and the snap-in column 4, and after the stud rod 502 passes through these connecting holes 503, a nut 504 located on the outer side of the other semicircular tube 501 is matched and connected on its outer peripheral side. In this way, the locking column 4 and the locking hole 3 are locked in the Y-axis direction. After the locking, the stud rod 502 passes through the connecting hole 503 and is fixed with the nut 504, so that the two semicircular tubes 501 form a circular tube for fixing. In this process, since the stud rod 502 passes through the rotating shaft 1, the locking column 4 and the other semicircular tube 501 in sequence, it is fixed on the X-axis. In this way, through the connection effect in both the X-axis and Y-axis directions, the blade 2 can be connected more stably without a protruding structure at the bottom.

[0027] In addition, since the outer circumference of the semicircular tube 501 is arc-shaped, the nut 504 may not be connected and tightened. To avoid this problem, a gasket is provided between the nut 504 and the corresponding semicircular tube 501 and is sleeved on the outer circumference of the stud rod 502. The gasket is an elastic ring.

[0028] It is worth mentioning that a plurality of evenly distributed fine holes can be opened through the blade 2, and these fine holes are used to promote the circulation of liquid, help the blade 2 to dissipate heat, reduce the temperature of the blade 2, and prevent the blade 2 from being deformed or damaged due to high temperature.
