Description

TECHNICAL FIELD

[0001] The present application belongs to the field of silage pits, and particularly relates to a silage sawing device. BACKGROUND

[0002] The silage pit is a place for placing silage grass for stacking, settling, sealing and fermentation, facilitates the preparation of large quantities of biological feed, and improves the storage quality of the feed in the anaerobic environment after packaging, thereby guaranteeing the efficiency and quantitative processing effect of the silage pit fermentation process.

[0003] However, when the raw materials in the silage pit are fermented, the sealing film covering the upper end of the silage pit needs to be opened, and the silage feed needs to be manually cut and taken out. Since the silage feed is subjected to anaerobic fermentation, some gases harmful to the human body are generated. Manual operation is not only tedious but also very dangerous. In addition, the silage feed fermentation pit is relatively high, and the operator is easy to be injured when taking out the silage feed at the top.

[0004] In the prior art, there is an invention patent with the application number CN202210989889.5 and the name of a silage feed taking-out device and working method, which relates to a taking-out mechanism and a taking-out method of a silage feed taking-out machine. The taking-out mechanism includes a rack, a taking-out head, a four-bar mechanism and a driving device. The four-bar mechanism includes a connecting rod I, a connecting rod and a connecting rod II. The left end of the connecting rod I is hinged to the rack through a hinge I, and the right end is hinged to the left end of the connecting rod through a hinge II. The left end of the connecting rod II is hinged to the rack through a hinge IV, and the right end is hinged to the connecting rod through a hinge III. The taking-out head is fixed to the right end of the connecting rod. The lower end of the driving device is hinged to the rack through a hinge VI, and the upper end is hinged to the connecting rod II through a hinge V. The beneficial effects of the present application are that when the driving device is stretched or contracted, the taking-out trajectory of the knife roll shaft is approximately a straight line perpendicular to the ground, which can avoid the formation of an arc-shaped cross section of the feed pile after taking out, which is easy to collapse and oxidize and deteriorate, and at the same time, the arc-shaped cross section is free from the restriction of the taking-out height and the stacking height of the feed pile.

[0005] As described above, the machine for automatically taking out the silage feed in the prior art needs to enter the silage pit, which will cause two problems. The user operating the machine needs to enter the silage pit together, which will cause the silage feed taken out at a high place to fall down, and the user will be at risk of being injured during use, which is dangerous. On the other hand, the prior art is not convenient for taking out the material at the end of the silage pit. SUMMARY

[0006] The purpose of the present application is to solve the problem in the prior art that the taking-out operation needs to enter the silage pit, and the operator needs to enter the silage pit together, which will cause the silage feed taken out at a high place to injure the operator and the operator to inhale harmful gas, which is dangerous.

[0027] In one specific embodiment of the present application, as shown in Figures 1 to 5 there is a silage sawing device for sawing and collecting silage in a silo 100, comprising a walking frame 200, a telescopic assembly 300 and a sawing assembly 400, the walking frame 200 is movably arranged in the silo 100;

[0028] The fixed end of the telescopic assembly 300 is arranged in the walking frame 200, and the extended end of the telescopic assembly 300 extends along the direction of gravity;

[0029] The sawing assembly 400 comprises a rack 410, a sawing roller 420 and a driving member 430, the rack 410 is connected to the extended end of the telescopic assembly 300, the sawing roller 420 is rotatably connected to the rack 410, the driving member 430 is arranged on the rack 410, and the driving member 430 is drivingly connected to the sawing roller 420. When taking silage from the silo 100, the silage is taken along a vertical plane, which is the taking section, that is, a layer of silage is taken from the taking section at a time. The sawing roller 420 of the present application can be any kind of roller with a cutter or a spike on the surface, which can be driven by the driving member 430 along the taking section to gradually saw down a layer of silage during the extension of the telescopic assembly 300.

[0030] In a specific implementation process, after the silage pit 100 is filled with silage and fermentation storage is carried out, when part of the silage needs to be taken, the sealing film laid on the silage pit 100 is opened, the walking frame 200 of the present application is erected on the silage pit 100 and travels along the extension direction of the long side of the silage pit 100, when the walking frame 200 moves to the material taking section, the extension end of the telescopic assembly 300 is extended, the rack 410 is displaced downward, the driving member 430 is actuated to drive the sawing roller 420 to rotate, the sawing roller 420 rotates while being driven by the rack 410, the sawing roller 420 is displaced downward along the material taking section, and the silage in the material taking section is continuously sawn into silage pieces from top to bottom and falls to the bottom of the silage pit 100, workers can use long-handled rakes or shovels to rake the silage pieces falling to the bottom of the silage pit 100 to the ground or into transport vehicles, and finally the sealing film is covered on the surface of the silage to wait for the next material taking operation. During the whole process, the operator and the machine of the present application do not need to enter the inside of the silage pit 100, thereby effectively avoiding the operator inhaling harmful gases generated by the closed fermentation of the silage.

[0031] In another implementation process, when the material taking is performed on the silage pit 100 for the first time, the end part of the silage pit 100 needs to be taken, because the silage pit 100 is filled with silage, the traditional material taking device cannot enter the silage pit 100, but the walking frame 200 of the present application can be erected on the silage pit 100 to drive the movable sawing assembly 400 to reach the end part, at this time the telescopic assembly 300 drives the movable sawing assembly 400 to extend downward, and the driving member 430 drives the sawing roller 420 to rotate to break the silage at the end part. After the broken silage is collected by workers, the sealing film is covered on the silage pit 100 to wait for the next material taking operation on the silage.

[0032] Beneficial effects: the walking frame 200 of the present application travels on the silage pit 100, so that the operator does not need to enter the bottom of the silage pit 100 to observe and control the walking frame 200 to reach the material taking section, and then the extension end of the telescopic assembly 300 is extended to drive the rack 410 to displace downward, the driving member 430 is actuated to drive the sawing roller 420 to rotate, the sawing roller 420 rotates while being driven by the rack 410, the sawing roller 420 is displaced downward along the material taking section, and the silage in the material taking section is continuously sawn into silage pieces from top to bottom and falls to the bottom of the silage pit 100. Workers only need to use long-handled rakes or shovels to rake the silage pieces falling to the bottom of the silage pit 100 to the ground or into transport vehicles. During the whole process, the operator and the machine of the present application do not need to enter the inside of the silage pit 100, thereby effectively avoiding the operator inhaling harmful gases generated by the closed fermentation of the silage.

[0033] In the above implementation process, if the sawing roller 420 adopts the roller with only spikes in the prior art, as the roller rotates, the spikes will rake the silage, it is difficult to cut the silage, and the material taking section after taking the silage will be rough and uneven, the rough and uneven material taking section increases the contact area of the silage at the material taking section with oxygen, so that the silage at the material taking section is easy to rot. In one possible embodiment, the sawing roller 420 comprises a roller body 421 and a plurality of cutters 422, the roller body 421 is rotatably connected with the frame 410, and the roller body 421 is drivingly connected with the driving member 430, a plurality of cutters 422 are densely arranged on the surface of the roller body 421, and the cutters 422 are arranged obliquely to the rotation direction of the roller body 421. If the cutters 422 are not provided with gaps, the cut silage is easy to adhere to the surface of the cutters 422 and will not fall off, so that gap regions are formed between adjacent cutters 422. In a specific implementation process, the roller body 421 is driven by the driving member 430 to rotate, and the cutters 422 densely arranged on the surface of the roller body 421 cut the silage at the material taking section. Since the cutters 422 are arranged obliquely to the rotation direction of the roller body 421, the cutters 422 will continuously cut the silage at the material taking section, forming a smooth material taking channel each time the cutters 422 cut the silage, and a plurality of smooth material taking channels form the material taking section, so that compared with the prior art, the material taking section formed by the present implementation process is more smooth and is not easy to oxidize and rot.

[0034] In the above implementation process, there are gap regions between the cutters 422, and the silage in the gap regions will protrude and have a larger contact area with oxygen, which is more prone to oxidation and rot. In addition, the silage is pressed tightly during loading, and it is easy for the cut silage to form large pieces that cannot be dispersed directly by using the cutters 422, so that the subsequent silage mixing and feeding need to be manually dispersed. In one possible embodiment, the sawing roller 420 further comprises a plurality of division spikes 423 distributed in the gap regions. Before the roller body 421 rotates to drive the cutters 422 to cut the silage, the division spikes 423 first divide the silage into vertical division lines one by one, and in this process, the silage to be cut by the cutters 422 is pressed to become loose and protruding. Then, each time the cutters 422 cut and shave the silage, the silage is divided into loose silage pieces by the division lines, and will not form large pieces. The loose silage pieces will not adhere to the cutters 422.

[0035] In the above implementation process, when the cutter 422 cuts and shaves the silage, the roller body 421 rotates and drives the cutter 422 to throw the cut silage along the tangent extension line of the rotation direction. The scattered silage is not easy to collect manually. In a possible embodiment, the rack 410 is provided with a guide arc plate 411 extending in the opposite direction of the rotation direction of the roller body 421 and semi-enclosing the sawing roller 420. The tangent of the lower end of the guide arc plate 411 is perpendicular to the ground. When the cutter 422 cuts and shaves the silage, the roller body 421 rotates and drives the cutter 422 to throw the cut silage along the tangent extension line of the rotation direction. The scattered silage will hit the guide arc plate 411 and then be blocked by the guide arc plate 411 and fall below the guide arc plate 411. Since the silage is cut from top to bottom at each time of taking and cutting, the cut silage is accumulated near the taking section, so that the taken silage is concentrated and is very convenient for subsequent collection.

[0036] In the above implementation process, when the cutter 422 cuts and shaves the silage, the roller body 421 rotates and drives the cutter 422 to throw the cut silage along the tangent extension line of the rotation direction. The scattered silage is not easy to collect manually. In a possible embodiment, the rack 410 is provided with a guide arc plate 411 extending in the opposite direction of the rotation direction of the roller body 421 and semi-enclosing the sawing roller 420. The tangent of the lower end of the guide arc plate 411 is perpendicular to the ground. When the cutter 422 cuts and shaves the silage, the roller body 421 rotates and drives the cutter 422 to throw the cut silage along the tangent extension line of the rotation direction. The scattered silage will hit the guide arc plate 411 and then be blocked by the guide arc plate 411 and fall below the guide arc plate 411. Since the silage is cut from top to bottom at each time of taking and cutting, the cut silage is accumulated near the taking section, so that the taken silage is concentrated and is very convenient for subsequent collection.

[0037] In the above implementation process, since the present application is driven by the walking frame 200 to take the material in the silo 100, if the walking frame 200 is skewed, it will cause the extension end of the telescopic assembly 300 to collide with the side wall of the silo 100, which is easy to cause damage to the device. In a possible embodiment, the silo 100 is symmetrically provided with a positioning track 110 on both sides, and the walking frame 200 is movably connected with the positioning track 110. The positioning track 110 and the walking frame 200 movably connect, so that the moving track of the walking frame 200 is constant.

[0038] Further, in a possible embodiment, the telescopic assembly 300 is a telescopic cylinder. The telescopic cylinder is convenient to use and mature in technology, avoids adding an additional driving motor, and has a large extension force, which can meet the required pressing force when the sawing roller 420 saws the material.

[0039] Further, in a possible embodiment, the lower end of the rack 410 is provided with a receiving cavity 210, and the fixed end of the telescopic assembly 300 is arranged in the receiving cavity 210. The receiving cavity 210 is used to accommodate the telescopic assembly 300 and the sawing assembly 400. After the receiving cavity 210 is used to accommodate the telescopic assembly 300 and the sawing assembly 400, the walking frame 200 can freely walk on the upper surface of the silage, and the protruding telescopic assembly 300 and the sawing assembly 400 at the bottom are prevented from colliding with the ground or the upper surface of the silage.

[0040] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation manner of the present application. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the implementation manners. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
