Detailed Description

The utility model will be further described with reference to the drawings and examples.

As shown in fig. 1 to 3, a multifunctional guillotine of the present utility model includes a casing 1 and a guillotine assembly 2 for guillotine material. The machine shell 1 is internally provided with a cutting cavity 11, the cutting assembly 2 is arranged in the cutting cavity 11, the cutting assembly 2 comprises a main shaft 21 and a moving tool rest 22 arranged on the main shaft 21, the main shaft 21 is rotationally connected with the machine shell 1, and the moving tool rest 22 is arranged on the main shaft 2. At least two first movable blades 23 are arranged on one side of the movable blade carrier 22, and at least two second movable blades 24 are arranged on the other side of the movable blade carrier. One side of the cutting cavity 11, which is located on the second moving knife 24, is provided with a feed cylinder 3, one end of which is communicated with the cutting cavity 11, one side of the cutting cavity 11, which is located on the first moving knife 23, is provided with a first feed inlet 12, and the first feed inlet 12 is provided with a grass feeding roller assembly 4. It will be appreciated that the bottom of the chopping chamber 11 is also provided with a discharge port (not shown). To facilitate feeding, the feed cylinder 3 is generally arranged obliquely downwards.

The first moving blade 23 is mainly used for cutting softer materials such as straw, forage and the like, and the second moving blade 24 is mainly used for cutting harder materials such as branches and the like. The first moving blade 23 and the second moving blade 24 are both conventional guillotine blades. The specific number of the first movable blades 23 and the second movable blades 24 may be 2 or any number above 2. The first movable blade 23 and the second movable blade 24 are generally uniformly arranged around the main shaft, respectively.

Because harder materials such as branches are harder, the grass conveying roller assembly 4 is harder to pass through, and when cutting, the cutting force of the cutting knife on the branches is larger, the grass conveying roller assembly 4 is fed through the transmission of the branches, so that the grass conveying roller assembly is extremely easy to damage and the like. Therefore, the existing cutting machine for cutting soft materials such as straws, forage and the like is difficult to directly cut harder materials such as branches and the like, and the use requirement of farmers cannot be met. According to the cutting machine disclosed by the utility model, as the first movable cutter 23 is arranged on one side of the movable cutter frame 22, the second movable cutter 24 is arranged on the other side of the movable cutter frame, and the feeding barrel 3 with one end communicated with the cutting cavity 11 is arranged on one side of the cutting cavity 11 positioned on the second movable cutter 24, harder materials such as branches can be fed into the cutting cavity 11 through the feeding barrel 3, then cut off by the second movable cutter 24, and finally flow out from the discharge hole of the cutting cavity. Because the feeding cylinder is adopted for feeding, the feeding cylinder 3 can well limit the swing of branches in the cutting process, and has a good protection effect on operators. When the straw, forage and other softer materials need to be cut, the materials are fed into the cutting cavity 11 from the first feed inlet 12 through the grass feeding roller assembly 4, and can be cut off by the first movable cutter 23. The multifunctional cutting machine provided by the utility model has the advantages that one side can be used for cutting harder materials such as branches, the other side can be used for cutting softer materials such as straws and forage, the machine is multifunctional, the user requirements can be better met, and the cutting harder materials and softer materials respectively use different cutting knives, so that the cutting knives with different hardness can be conveniently selected as the first movable knife 23 and the second movable knife 24 according to the soft and hard characteristics of the materials, the maintenance is more convenient, and the use is more convenient.

The number of the first movable blades 23 and the number of the second movable blades 24 may be the same or different. As shown in fig. 2 and 3, in the present utility model, the first moving blades 23 and the second moving blades 24 are arranged in one-to-one correspondence, and the cutting edges of the first moving blades 23 and the second moving blades 24 which are arranged correspondingly are arranged in a staggered manner along the cutting direction of the cutting machine. The first movable cutters 23 and the second movable cutters 24 are arranged in one-to-one correspondence, namely: the number of the first movable cutters 23 is the same as that of the second movable cutters 24, and one second movable cutter 24 is correspondingly arranged on one side of each first movable cutter 23. Along the cutting direction of the cutter, the cutting edges of the first moving blade 23 and the second moving blade 24 which are correspondingly arranged are arranged in a staggered manner, so that the main shaft 21 can be stressed better. Specifically, the cutting edge of the first movable blade 23 may be located in front of or behind the cutting edge of the second movable blade 24 in the cutting direction of the cutter.

The movable blade carrier 22 may be of various structures made of a plate or a profile. As shown in fig. 2 and 3, in the embodiment of the present utility model, the movable blade carrier 22 includes a plurality of mounting plates 221 that are disposed in one-to-one correspondence with the first movable blades 23 and are disposed along the radial direction of the spindle 21. The mounting plate 221 is fixed to the main shaft 21 and is annularly disposed around the main shaft 21. The mounting plate 221 has a Z-shaped structure, and includes a base plate 2211, and a first bending portion 2212 and a second bending portion 2213 disposed on two sides of the base plate 2211. The first movable blade 23 is mounted on the first bending portion 2212 of the corresponding mounting plate 221, and the second movable blade 24 is correspondingly mounted on the second bending portion 2213, so that a cutting edge dislocation arrangement is formed, and the structure of the movable blade holder 22 is simpler. Specifically, the mounting plate 221 may be fixed to the main shaft 21 by welding, bolting, clamping, etc., and may be directly fixed to the main shaft, or by other things such as: and the shaft sleeve is fixed on the main shaft. The movable knife is generally mounted on the bending part in a bolt connection mode. The bending portion may be integrally formed with the substrate 2211, or may be disposed on the substrate 2211 by welding. In the above structure, the mounting plate 221 (the base plate 2211) can generate centrifugal wind force, can play the role of a blade, and can timely discharge materials from the discharge hole of the cutting cavity. In order to crush the cut material to a certain extent, the outer end of the base plate 2211 is provided with a saw tooth structure.

Generally, the first moving blade 23 is a thin cutting blade with low strength and good sharpness so as to cut softer materials, while the second moving blade 24 is a thick cutting blade with large thickness and high hardness so as to cut harder materials. If the first movable cutter 23 is easy to cut into harder materials when cutting into harder materials, the first movable cutter 23 is extremely easy to damage. For this purpose, the cutting edge of the first movable blade 23 is preferably located on the front side of the cutting edge of the second movable blade 24, which is correspondingly located, in the cutting direction of the cutter. As shown in fig. 3, the cutting direction 5 of the cutting machine is clockwise, that is, the main shaft 21 rotates clockwise, so that the cutting edge of the first moving blade 23 passes through the feeding cylinder 3 before the corresponding second moving blade 24, so that the harder material does not reach the first moving blade 23 in the high-speed rotation process of the main shaft, and after the harder material is cut off by the second moving blade 24, the cutting part cannot collide with the cutting edge of the subsequent first moving blade 23 under the action of the substrate 2211, so that the first moving blade 23 can be better protected.

Since the second movable knife 24 cuts a harder object and is stressed more, the stress of the second bending portion 2213 is correspondingly greater. For this purpose, a reinforcing plate 25 is disposed on a side of the second bending portion 2213 away from the second movable blade 24 along a radial direction of the main shaft 21, and the reinforcing plate 25 is disposed at an end of the second bending portion 2213 close to the main shaft 21. The reinforcing plate 25 is disposed at one end of the second bending portion 2213 near the main shaft 21 and along the radial direction of the main shaft 21, so that the reinforcing plate not only can play a reinforcing role, but also can generate centrifugal wind force at a position near the main shaft, which is more beneficial to discharging materials.

Generally, the softer material is mainly used as feed and needs to be cut more finely, and for this purpose, a third moving blade 26 is further arranged between the adjacent first moving blades 23 to increase the number of cutting blades at the side of the first feed inlet, so that the material entering from the first feed inlet is cut more finely. Optimally, the cutting edge of the third movable cutter 26 is at the front side of the reinforcing plate 25 along the cutting direction of the cutter. In this way, the centrifugal wind force of the reinforcing plate 25 can blow the material cut by the third movable cutter 26 radially outwards along the cutting cavity 11 in time.

In the embodiment of the present utility model, as shown in fig. 4, the grass feeding roller assembly 4 includes an upper grass feeding roller 41 and a lower grass feeding roller 42 rotatably connected to the casing 1, and the upper grass feeding roller 41 is disposed above the lower grass feeding roller 42 and is disposed opposite to the lower grass feeding roller 42. When feeding, the upper grass feeding roller 41 and the lower grass feeding roller 42 are driven by the driving device to rotate synchronously in opposite directions, so that softer materials can be fed into the cutting cavity from the position between the upper grass feeding roller 41 and the lower grass feeding roller 42. In some embodiments, the grass roller assembly 4 includes only an upper grass roller 41, the upper grass roller 41 being disposed above the feed plate 44.

Specifically, the casing 1 is provided with a slider 43 that is slidably disposed up and down with the casing 1, and the upper grass feeding roller 41 is rotatably connected with the slider 43. Compared with the rotary connection mode of the upper grass feeding roller 41 and the machine shell 1, the upper grass feeding roller 41 in the structure can be adaptively adjusted according to the quantity of materials between the upper grass feeding roller 41 and the lower grass feeding roller 42, namely, when the materials are more, the upper grass feeding roller automatically moves upwards by a certain distance under the reaction force of the materials, otherwise, automatically moves downwards under the action of gravity so as to ensure that the materials are compacted. The structure is more convenient for feeding materials.
