Description

Technical Field

[0001] The present invention relates to the technical field of material crushing devices, and more particularly to an environmentally friendly agricultural material crushing device. Background Art

[0002] In current agricultural production, agricultural materials are diverse in type and have different crushing requirements. Traditional agricultural material crushing devices are difficult to meet the operational requirements of complex scenarios. For example, when making silage, the material particle size must be uniform. When processing straw, it is necessary to achieve efficient graded crushing while also meeting the flexible crushing requirements of high-humidity and impurity-containing materials. When facing these different requirements, existing crushing devices often have problems such as poor crushing effect, cumbersome crushing steps, easy breakage of blades, and easy overload of motors. They cannot meet the diverse crushing requirements and complex application scenarios at the same time.

[0003] Traditional agricultural material crushing devices usually have the following shortcomings: First, they cannot take into account the different material characteristics and crushing requirements. For example, when processing silage, traditional crushers cannot accurately control the particle size uniformity, affecting the quality of the feed; second, they have poor adaptability to complex materials with high humidity and high impurities. When encountering wet straw or materials mixed with stones and wires, the blades are prone to breakage, the motor is overloaded, and entanglement and blockage are prone to occur, resulting in a high equipment failure rate. In view of this, we propose an environmentally friendly agricultural material crushing device. Summary of the Invention

[0004] The purpose of the present invention is to provide an environmentally friendly agricultural material crushing device to solve the technical problem of poor crushing performance of complex materials with high humidity and high impurity content.

[0006] When the splint is unfolded, it moves upward, and the flat clamping surfaces on the inner walls on both sides of the splint are fitted and fixed with the plane of the crushing heads, so that the crushing heads are evenly arranged in a straight line along the crushing axis, and can perform equal-spaced and uniform impact crushing on straw and other rod-shaped materials; when the splint is unfolded again, the crushing heads are fitted and fixed with the inclined surface through the flat clamping surfaces, and the crushing heads are still arranged linearly along the axial direction, and each crushing head is at a certain angle to the rotating axis, and the whole is spirally distributed, which can perform graded crushing on straw and other rod-shaped materials;

[0007] When the clamping plates are gathered together, the flat clamping surface does not contact the flat and inclined surfaces on the crushing heads, so that several crushing heads can rotate axially, which can flexibly crush and crush rod-shaped materials such as straw with high humidity and high impurity content.

[0008] The present invention has three high-efficiency crushing modes. In the uniform crushing mode, the splint fits flat against the crushing head, fixing the crushing head in a linear array. This allows for evenly spaced and uniform impact on rod-shaped materials such as straw, resulting in uniform particle size after crushing, meeting stringent particle size requirements for applications such as silage. In the graded crushing mode, the splint fits in with the inclined surface of the crushing head, creating a spiral distribution of the crushing heads, achieving a gradient crushing pattern of "coarse at the front and fine at the back," reducing the number of crushing steps and improving efficiency. In the flexible crushing mode, the splints converge to allow the crushing head to be flexibly connected. With the rope tightened, the crushing head can be passively swung to avoid obstacles when encountering hard objects or highly humid materials, preventing blade breakage and motor overload. This significantly improves efficiency when processing water-containing straw or debris, making it highly suitable for complex operations such as straw return to the field.

[0047] Specifically, the motor drives the slide bar 25 to expand or gather the plurality of splints 28. When expanding, the splints 28 move upward, and the flat clamping surfaces 281 on the inner walls of the two sides of the splints 28 fit with the flat surfaces 291 on the crushing heads 29, so that the plurality of crushing heads 29 in a linear hinged array are fixed, so that the plurality of crushing heads 29 are evenly arranged in a straight line along the crushing axis, and can perform equal-spaced and uniform impact crushing processing on rod-shaped materials such as straw; when the motor drives the splints 28 to expand again, the rounded corner surface 282 slides on the inclined surface 292, so that the flat clamping surfaces 281 on the inner walls of the two sides of the splints 28 fit with the flat surfaces 291 on the crushing heads 29, so that the plurality of crushing heads 29 in a linear hinged array are fixed, and the plurality of crushing heads 29 are evenly arranged in a straight line along the crushing axis, so that the straw and other rod-shaped materials can be evenly spaced and evenly crushed; when the motor drives the splints 28 to expand again, the rounded corner surface 282 slides on the inclined surface 292, so that the flat clamping surfaces 281 on the inner walls of the two sides of the splints 28 fit with the flat surfaces 291 on the crushing heads 29, so that the plurality of crushing heads 29 in a linear hinged array are fixed, and the plurality of crushing heads 29 are evenly arranged in a straight line along the crushing axis, and can perform equal-spaced and uniform impact crushing processing on the straw and other rod-shaped materials; The surface 281 fits with the inclined surface 292 on the crushing head 29, and the several crushing heads 29 are still arranged linearly along the axial direction, and each crushing head 29 is at a certain angle to the rotating axis, and the whole is spirally distributed, which can perform graded crushing processing on rod-shaped materials such as straw; when the splints 28 are gathered, the flat clamping surface 281 does not contact the flat surface 291 and the inclined surface 292 on the crushing head 29, so that the several crushing heads 29 are movably connected to the surface of the inserted rod on the two relative mounting seats 22, which can flexibly crush and crush soil on rod-shaped materials such as straw with high humidity and high impurity content.

[0048] The present invention has multiple usage modes, including a uniform crushing mode and a uniform crushing mode: the clamping plate 28 is fitted with the plane 291 of the crushing head 29, so that the crushing head 29 is fixed in a linear array, and rod-shaped materials such as straw can be evenly and evenly struck. The particle size of the crushed materials is consistent, which meets the needs of scenarios such as silage that have high requirements for particle size uniformity; a graded crushing mode: the clamping plate 28 is matched with the inclined surface 292 of the crushing head 29, so that the crushing head 29 is spirally distributed, realizing gradient crushing from coarse at the front to fine at the back, with preliminary crushing by shearing at the front and fine processing by hitting and kneading at the back, thereby reducing the number of crushing steps; a flexible crushing mode: when the clamping plates 28 are gathered together, the crushing head 29 is movably connected, and cooperates with the tightening of the rope. When encountering hard objects or high-humidity materials, it can be passively swung to avoid obstacles, thereby avoiding blade breakage and motor overload. The crushing efficiency of water-containing straw or miscellaneous materials is improved, which is suitable for complex scenarios such as returning straw to the field.

[0049] Example 2, as Figure 3 and Figure 10-11As shown, the locking assembly 3 includes a protective cover 31, which is movably sleeved in the left hole on the hood 1, and the first motor 26 is fixedly sleeved inside the protective cover 31. The left end of the protective cover 31 is fixedly connected to a top cylinder 32. The left hole on the hood 1 is provided with a plurality of first semicircular grooves 33 in a circular array along the edge, and the end of the protective cover 31 is provided with a plurality of second semicircular grooves 34 in a circular array along the edge, and the first semicircular grooves 33 and the second semicircular grooves 34 in corresponding positions form a circular hole, which can be adjusted. A plurality of insertion holes 35 are provided on one side of the disk 27 corresponding to the position of the second semicircular groove 34, and a spiral block 351 is fixedly connected to the inside of each insertion hole 35, and a pin 36 is fixedly connected to the output end of the top cylinder 32 in a circular array, and a spiral groove 361 is provided on the end surface of each pin 36, and the spiral groove 361 is movably adapted to the spiral block 351, and a semicircular rod 362 is arranged on the surface of each pin 36, and the semicircular rod 362 is adapted to the first semicircular groove 33 and the second semicircular groove 34.

[0050] Specifically, when the motor is used to adjust the expansion or contraction of the plurality of splints 28, the top cylinder 32 drives the pin 36 to move to the left, and the pin 36 rotates and adapts with the spiral block 351 through the spiral groove 361, causing the pin 36 to rotate, so that the semicircular rod 362 rotates inside the first semicircular groove 33, so that the protective cover 31 is fixed to the machine cover 1; when crushing materials, the top cylinder 32 drives the pin 36 to move to the right, and the pin 36 is inserted into the socket 35 through the spiral groove 361 and rotates, causing the semicircular rod 362 to rotate inside the second semicircular groove 34, so that the protective cover 31 is movably connected to the machine cover 1, so as to prevent the first motor 26 from rotating due to the reaction force when adjusting the splint 28 or crushing, thereby affecting the adjustment or crushing.

[0051] The present invention realizes the rapid switching between the fixed and movable states of the protective cover 31 and the machine cover 1 through the screw cooperation between the top cylinder 32 and the latch 36; locks the motor to prevent displacement when adjusting the splint 28; allows the motor to float and buffer the reaction force during crushing, thereby extending the life of the equipment and improving the operating efficiency compared with traditional manual adjustment.

[0052] Example 3, as Figure 6 and Figure 10 As shown, the anti-collision component 4 includes a support rod 41, which is fixedly connected to one side of the adjustment disk 27. A ratchet 42 is fixedly sleeved in the hole of the limit disk 23. The support rod 41 is close to the end of the limit disk 23 and is movably connected to a plurality of pawls 43 in a circular array, and the ratchet 42 is engaged with the pawl 43. A rope 44 is movably sleeved on the end surface of each crushing head 29, and the rope 44 is spirally wound around the surface of the support rod 41.

[0053] When the crushing heads 29 are flexibly crushing, the regulating disk 27 rotates, causing the ropes 44 to be tightened. During the rotation, the crushing heads 29 rotate axially relative to the rods on the two mounting seats 22, preventing the crushing heads 29 from shaking irregularly and colliding with the inner cavity of the machine tool.

[0054] The ratchet 42 of the present invention is engaged with the pawl 43, and combined with the tightening of the rope, the shaking range of the crushing head 29 is limited, and only axial swing is allowed, thereby avoiding collision between the crushing head 29 and the machine cover 1. When encountering foreign objects, the pawl 43 automatically slips to prevent the motor from overloading and improve the service life.

[0055] Working principle: This embodiment provides an environmentally friendly agricultural material crushing device, which performs evenly spaced and uniform impact crushing processing on rod-shaped materials such as straw: first, the top cylinder 32 is operated through the external control system, and the top cylinder 32 drives the pin 36 to move to the left. At this time, the spiral groove 361 on the pin 36 is adapted to the rotation of the spiral block 351, causing the pin 36 to rotate half a circle, and the semicircular rod 362 rotates inside the first semicircular groove 33, so that the first motor 26 is fixed to the hood 1, and then the first motor is made to rotate half a circle through the external circuit mechanism. 26 drives the adjusting disk 27 to rotate, and the plurality of slide bars 25 are expanded outward, causing the clamping plates 28 to expand outward. When the flat clamping surfaces 281 of the inner walls on both sides of the clamping plates 28 are in contact with the flat surfaces 291 on the crushing heads 29, the plurality of crushing heads 29 are fixed, so that the plurality of crushing heads 29 are evenly arranged in a straight line along the crushing axis direction. Then, the motor base 11 is driven by the external circuit mechanism to rotate the plurality of crushing heads 29, and the driving motor drives the transmission belt 132 to move, so that the rod-shaped materials such as straw are evenly spaced and evenly struck and crushed.

[0056] Gradual crushing of rod-shaped materials such as straw: On the basis of the fixed arrangement of the plurality of crushing heads 29 in a linear array, the first motor 26 drives the adjustment disk 27 to rotate again, and the plurality of slide bars 25 are extended outward. At this time, the rounded surface 282 on the clamping plate 28 slides on the inclined surface 292, so that the flat clamping surface 281 fits with the inclined surface 292 on the crushing head 29. The plurality of crushing heads 29 are still arranged linearly along the axial direction, and each crushing head 29 forms a certain angle with the rotation axis, and the whole is spirally distributed. During the crushing process, straw and other rod-shaped materials can be graded and crushed;

[0057] Flexible crushing of rod-shaped materials such as straw: first, the first motor 26 is fixed to the hood 1 through the top cylinder 32, and then the adjusting disk 27 is driven to rotate by the first motor 26, so that the several slide rods 25 gather and move, wherein the flat clamping surface 281 does not contact the plane 291 and the inclined surface 292, and during the rotation of the adjusting disk 27, the support rod 41 is driven to rotate, and the several ropes 44 are tightened, so that the several crushing heads 29 can only shake axially, and then driven by the top cylinder 32, the first motor 26 and the hood 1 are moved, and flexible crushing and soil crushing of rod-shaped materials such as straw with high humidity and high impurity content are carried out.
