Description

Technical Field

[0001] The invention relates to the field of feed processing, in particular to a grain feed grinding and crushing device. Background Art

[0002] Grain feed grinding and crushing is an important link in feed processing. The seed coat and cell wall of grains are relatively tough, and it is difficult for animals to digest them directly. Through grinding and crushing, the structure of the grains is destroyed, making it easier for the internal nutrients to be exposed, making it easier for animal digestive enzymes to contact them, thereby improving the digestibility. The grain feed after crushing becomes smaller in size and finer in texture, making it easier for animals to eat and chew, and the palatability is improved, thereby increasing the animal's feed intake. The grain feed that has been ground and crushed can be better mixed with other feed raw materials to ensure the consistency of the nutrient content of the feed and avoid uneven nutritional intake of animals due to uneven feeding.

[0003] The existing grain feed grinding and crushing device can be adjusted to grind and crush grains of different particles. This can be achieved by setting a telescopic rod and extending or shortening the telescopic rod to adjust the position of the grinding roller. In a grinding and crushing process, since the grains after grinding and crushing are large and small, the particles that do not meet the particle size requirements are removed by screening, which can ensure the consistency of the particle size of each batch of feed, thereby ensuring the stability of the feed products in terms of nutritional content and palatability. In the process of screening after grinding and crushing, the size of the sieve holes must also be adjusted accordingly with the position adjustment of the grinding roller. It is necessary to add a complex intelligent control system to the screening device, which significantly increases the equipment cost.

[0016] Compared with the prior art, the present invention provides a grain feed grinding and crushing device having the following

[0017] Beneficial effects:

[0018] 1. In the actual process of grain feed production and processing, the grain feed grinding and crushing device can drive the cylinder to rotate by adjusting the adjustment handle, and the second spiral groove cooperates with the L-shaped block to drive the connecting ring and the second screen plate to move. The holes on the surface of the first screen plate are misaligned with the holes on the surface of the second screen plate, and new screen holes are formed at the connection between the two holes.

[0019] 2. The grain feed grinding and crushing device, when it is necessary to replace the grains that produce small particles, due to the cooperation between the adjusting block and the strip groove, the adjustment distance of the adjusting plate is fixed each time, that is, the position of the abrasive roller is not adjusted once. During the adjustment process, the grains can still be ground and crushed. The degree of crushing each time is small, and the impact force and friction force on the grinding equipment are small, which can reduce the wear rate of the equipment and extend the service life of the equipment. Each grinding can further refine and adjust the particles, so that the particle size of the final grain is more consistent, thereby ensuring the production quality of the grain feed.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig.10 , Fig.13 and Fig.14A grain feed grinding and crushing device comprises a material barrel 1, a conical box 11 fixedly connected to the bottom of the material barrel 1, a material outlet 12 opened at the bottom of the conical box 11 and a mounting hole 13 opened on the surface of the conical box 11, a first motor 2 is fixedly connected to the inner wall of the conical box 11, an abrasive roller 3 is arranged above the first motor 2, a rectangular column 4 is fixedly connected to the bottom of the abrasive roller 3, a transmission column 5 is slidably connected to the lower end of the surface of the rectangular column 4, the lower end of the transmission column 5 is fixedly connected to the output shaft of the first motor 2, an adjustment mechanism 6 for automatically adjusting the upward movement of the abrasive roller 3 is arranged at one end of the surface of the rectangular column 4 close to the abrasive roller 3, an inclined plate 14 is fixedly connected to the bottom of the conical box 11, a mounting frame 15 is installed on the surface of the inclined plate 14 through a torsion spring, a first sieve plate 16 is fixedly connected to the surface of the mounting frame 15, and a second sieve plate 17 is slidably connected to the upper surface of the first sieve plate 16;

[0037] The adjusting mechanism 6 includes a first connecting column 61 rotatably connected to one end of the surface of the rectangular column 4 close to the abrasive roller 3, two first connecting columns 61 surfaces away from the rectangular column 4 are slidably connected to the second connecting column 62, the hole wall of the mounting hole 13 is rotatably connected to the rotating column 63, the two second connecting columns 62 and the rotating column 63 are rotatably connected through a one-way bearing, the second connecting column 62 is slidably connected to the end away from the first connecting column 61 by a third connecting column 64, the two third connecting columns 64 are rotatably connected to the ends of the second connecting columns 62 away from the second connecting columns 62 by an adjusting plate 65, and the surface of the adjusting plate 65 is slidably connected to the connecting plate 6 6. The surface of the adjustment plate 65 is provided with strip grooves 67 at equal intervals below the connecting plate 66. The connecting plate 66 is fixedly connected to the conical box 11. The end of the surface of the connecting plate 66 away from the conical box 11 is rotatably connected to a column 68. The end of the surface of the column 68 away from the connecting plate 66 is fixedly connected to an adjustment block 69. The lower part of the column 68 is rotatably connected to an adjustment column 610 through a one-way bearing. The outer side of the adjustment column 610 is sleeved with a fixed sleeve 611. The lower end of the fixed sleeve 611 is fixedly connected to a material receiving box 612. A suction mechanism is provided below the material receiving box 612. The suction mechanism is installed in conjunction with the material barrel 1.

[0038] It should be noted that the first motor 2 is started, driving the transmission column 5 to rotate. The upper end surface of the transmission column 5 is provided with a column groove that can be slidably plugged with the rectangular column 4. The transmission column 5 rotates together with the rectangular column 4, thereby driving the abrasive roller 3 to rotate, placing the grains in the barrel 1. As the abrasive roller 3 rotates, the grains are ground and crushed. The ground and crushed grains can be placed in the cone box 11, slide from the discharge port 12 at the bottom of the cone box 11 to the surface of the second sieve plate 17, and the first sieve plate 16 and the second sieve plate 17 are staggered to form sieve holes for screening, and the larger grains are removed. The grains slide down the surface of the second sieve plate 17 into the receiving box 612, and the smaller grains are discharged through the sieve holes. The suction mechanism can suck the grains regularly and transport the grains in the receiving box 612 to the material barrel 1 for re-grinding and crushing. In the actual grain feed production process, when it is necessary to change to produce smaller grains, there is no need to stop the equipment. Just turn the adjustment handle 132, and the cylinder 127 rotates with the adjustment handle 132, so that the L-shaped block 129 and the second spiral groove 128 can move relative to each other, thereby driving the connecting ring and the second The sieve plate 17 moves, so that the first sieve plate 16 and the second sieve plate 17 continue to be misaligned, and the sieve hole area is reduced. At this time, the position of the grinding roller 3 is not adjusted, and the grain particles discharged from the discharge port 12 slide along the surface of the second sieve plate 17 into the receiving box 612. The grains accumulate in the receiving box 612, thereby overcoming the friction between the first friction ring 617 and the fixed sleeve 611 and the elastic force of the second spring, and the protrusion 616 can generate relative movement with the first vertical groove 613, the first spiral groove 615 and the second vertical groove 614, thereby driving the column 6 8 and the adjusting column 610 rotate, and the adjusting block 69 cooperates with the strip groove 67 to drive the adjusting plate 65 to move downward, and the first connecting column 61, the second connecting column 62 and the third connecting column 64 drive the rectangular column 4 and the abrasive roller 3 to move upward, and the distance between the abrasive roller 3 and the upper end of the inner wall of the conical box 11 is shortened, and the adjustment is completed, so that smaller grain particles can be ground and crushed. Grains of different particle sizes can be produced by only rotating the adjusting handle 132 to change the size of the sieve hole, without adding a complex intelligent control system for control, thereby reducing equipment costs;

[0039] When it is necessary to replace the grains that produce small particles, due to the cooperation between the adjustment block 69 and the strip groove 67, the adjustment distance of the adjustment plate 65 is fixed each time, that is, the position of the abrasive roller 3 is not adjusted once. During the adjustment process, the grains can still be ground and crushed. Compared with the prior art, the crushed grain particles are ground and crushed for the second time without changing the position of the abrasive roller 3. The degree of crushing each time is smaller, and the impact force and friction force on the grinding equipment are smaller, which can reduce the wear rate of the equipment and extend the service life of the equipment. Each grinding can further refine and adjust the particles, so that the particle size of the final grain is more consistent, thereby ensuring the production quality of grain feed.

[0040] See also Figure 3 and Figure 6 , a conical block 18 is fixedly connected to one end of the surface of the transmission column 5 away from the first motor 2, a top block 19 is matched and installed on the outer side of the conical block 18, a cross column 110 is fixedly connected to the surface of the top block 19 away from the conical block 18, an annular block 111 is fixedly connected to one end of the surface of the cross column 110 close to the top block 19, a first spring 112 is fixedly connected to the surface of the annular block 111 away from the top block 19, an L-shaped plate 113 is fixedly connected to one end of the first spring 112 away from the annular block 111, an end of the L-shaped plate 113 away from the cross column 110 is fixedly connected to the inner wall of the cone box 11, the L-shaped plate 113 is slidably connected to the cross column 110, an end of the cross column 110 away from the top block 19 is fixedly connected to a limiting block 114, a limiting gear 115 is fixedly connected to the middle part of the surface of the rotating column 63, and a second friction ring 116 is sleeved on the surface of the cross column 110 between the limiting block 114 and the L-shaped plate 113;

[0041] It should be noted that when the first motor 2 drives the transmission column 5 to rotate, the conical block 18 is fixedly connected to the transmission column 5, and the conical block 18 rotates as the transmission column 5 rotates. The top block 19 contacts the surface of the conical block 18, so that the cross column 110 can move in the direction away from the transmission column 5, the first spring 112 is compressed, and the limit block 114 cooperates with the limit gear 115 to limit the rotation of the rotating column 63. Due to the friction between the second friction ring 116 and the cross column 110, under the elastic force of the first spring 112, the cross column 110 and the limit block 114 are not It will be reset immediately, that is, it can maintain the limiting state of the rotating column 63, and the conical block 18 rotates with the rotation of the transmission column 5, and the conical block 18 will continuously contact with the top block 19, thereby ensuring the adjusted state of the top block 19, so that the rotating column 63 can be stably limited. After the entire device stops operating, under the elastic force of the first spring 112, relative movement will occur between the cross column 110 and the second friction ring 116, the limiting block 114 is separated from the limiting gear 115, and the abrasive roller 3 can be reset, and the elastic force of the third spring 118 is used to provide a buffer for the abrasive roller 3.

[0042] See also Figure 1 , Figure 5 , Figure 8 , Fig.10 and Fig.12, the surface of the adjusting column 610 is provided with a first vertical groove 613, a second vertical groove 614 and a first spiral groove 615, the first vertical groove 613 and the second vertical groove 614 are both connected to the first spiral groove 615, the groove wall of the first vertical groove 613 is slidably connected with a protrusion 616, and the protrusion 616 is fixedly connected to the inner wall of the fixed sleeve 611, and the surface of the adjusting column 610 is located above the first vertical groove 613 and is fixedly connected with a first friction ring 617, and the first friction ring 617 is installed in cooperation with the fixed sleeve 611, and the outer side of the material receiving box 612 is slidably connected with a mounting plate 618, and the end of the mounting plate 618 away from the material receiving box 612 is fixedly connected to the conical box 11, and the surface of the mounting plate 618 is provided with a groove 619 near the material receiving box 612, and the groove wall of the groove 619 is symmetrically slidably connected with a fixed column 620, and the outer side of the fixed column 620 is sleeved with a second spring, and the upper ends of the two fixed columns 620 are fixedly connected to the material receiving box 612;

[0043] It should be noted that after adjusting the size of the sieve holes by rotating the adjustment handle 132, due to the reduction of the sieve holes, larger grains cannot slide down through the sieve holes and are finally placed in the receiving box 612. The receiving box 612 continuously receives grains, and the gravity gradually increases, overcoming the friction between the fixed sleeve 611 and the first friction ring 617, as well as the elastic force of the second spring. The protrusion 616 first moves relative to the first vertical groove 613, then moves relative to the first spiral groove 615, and then moves relative to the second vertical groove 614, until it moves to the lower end of the second vertical groove 614. In this process, the second spring is gradually compressed. Since the column 68 and the adjustment column 610 are rotatably connected via a one-way bearing, when the protrusion 616 moves away from the column 68, When moving downward, the relative movement between the protrusion 616 and the first spiral groove 615 can drive the column 68 to rotate, otherwise, it cannot, and then it can drive the column 68 and the adjusting block 69 to rotate one circle. The adjusting block 69 cooperates with the strip groove 67 to drive the adjusting plate 65 to move downward, which is driven by the first connecting column 61, the second connecting column 62 and the third connecting column 64 to drive the abrasive roller 3 to move upward. Since the rotating column 63 and the second connecting column 62 are rotatably connected by a one-way bearing, the second connecting column 62 can be driven to rotate during the downward movement of the adjusting plate 65, otherwise it cannot. The limit block 114 can be in close contact with the limit gear 115 to limit the rotation of the rotating column 63, so that the abrasive roller 3 can be in a stable state after being adjusted and moved.

[0044] See also Figure 5The end of the surface of the rectangular column 4 close to the abrasive roller 3 is rotatably connected with the first rotating ring 117, and the two first connecting columns 61 are rotatably connected with the first rotating ring 117. A third spring 118 is fixedly connected below the first rotating ring 117. The third spring 118 is sleeved on the outside of the rectangular column 4, and the end of the third spring 118 away from the first rotating ring 117 is fixedly connected with the second rotating ring, and the second rotating ring is rotatably connected with the conical block 18; the initial state of the third spring 118 is a compressed state.

[0045] It should be noted that the reaction force generated by the compression of the third spring 118 acts on the surface of the first rotating ring 117, reducing the force required for adjusting the position of the abrasive roller 3, making it easier to adjust the position of the abrasive roller 3, and after the entire device is closed, the abrasive roller 3 can be reset due to its own gravity, and the elastic force of the third spring 118 can support the abrasive roller 3.

[0046] See also Figure 5 and Figure 7 , a third rotating ring 120 is fixedly connected to the bottom of the conical block 18, a fourth spring 121 is fixedly connected to the bottom of the third rotating ring 120, and a fourth rotating ring 122 is fixedly connected to one end of the fourth spring 121 away from the third rotating ring 120, the third rotating ring 120, the fourth rotating ring 122 and the fourth spring 121 are all sleeved on the outside of the transmission column 5, and a transverse plate 123 is rotatably connected to the bottom of the fourth rotating ring 122, one end of the transverse plate 123 is sleeved on the outside of the transmission column 5, and the other end of the transverse plate 123 is rotatably connected to a fourth connecting column 124, and one end of the fourth connecting column 124 away from the transverse plate 123 is rotatably connected to the mounting frame 15, and a first trapezoidal block 125 uniformly distributed in an annular shape is fixedly connected to the lower surface of the transverse plate 123 below the fourth spring 121, and a circular disk 126 is fixedly connected to the surface of the transmission column 5 below the transverse plate 123, and a second trapezoidal block uniformly distributed in an annular shape is fixedly connected to the upper surface of the circular disk 126, and the first trapezoidal block 125 is clamped with the second trapezoidal block;

[0047] It should be noted that, by utilizing the elastic force of the fourth spring 121, the first trapezoidal block 125 and the second trapezoidal block can be stably connected. In the process of the first motor 2 driving the transmission column 5 to rotate, the multiple second trapezoidal blocks on the surface of the disk 126 will produce relative rotation with the first trapezoidal block 125, thereby driving the cross plate 123 to shake up and down continuously. The cross plate 123 is rotatably connected to the mounting frame 15 through the fourth connecting column 124, thereby driving the mounting frame 15, the first sieve plate 16 and the second sieve plate 17 to shake continuously, so that the screening effect is better, and smaller grain particles can slide through the sieve holes to the bottom of the first sieve plate 16, and larger grain particles will slide down along the surface of the second sieve plate 17 and enter the receiving box 612.

[0048] See also Figure 2 , Fig.11 and Fig.13 The first sieve plate 16 is rotatably connected to a cylinder 127 on the side, a second spiral groove 128 is provided on the outside of the cylinder 127, an L-shaped block 129 is mounted on the groove wall of the second spiral groove 128, and a connecting ring is fixedly connected to the side of the second sieve plate 17 above the cylinder 127, the connecting ring is sleeved on the outside of the cylinder 127, and the L-shaped block 129 is fixedly connected to the connecting ring;

[0049] It should be noted that when it is necessary to adjust the sieve hole to reduce or increase, the adjustment handle 132 is rotated, and the cylinder 127 rotates along with the adjustment handle 132, causing relative movement between the second spiral groove 128 and the L-shaped block 129, thereby driving the connecting ring, the L-shaped block 129 and the second sieve plate 17 and the first sieve plate 16 to move relative to each other, thereby adjusting the size of the sieve hole to facilitate grinding and crushing of grain particles of different particle sizes according to actual grain feed production needs.

[0050] See also Figure 2 , Fig. 9 and Fig.11 A movable rod 130 is arranged on the outer side of the cylinder 127, and the end of the movable rod 130 away from the second sieve plate 17 is slidably connected to a fixed rod 131, and the end of the fixed rod 131 away from the movable rod 130 is fixedly connected to an adjusting handle 132, and the surface of the adjusting handle 132 close to the cylinder 127 is fixedly connected to a protrusion 133, and the end of the protrusion 133 away from the adjusting handle 132 is fixedly connected to a connecting spring, and a rectangular groove 119 is formed on the end surface of the cylinder 127 away from the first sieve plate 16, and the end of the connecting spring away from the protrusion 133 is fixedly connected to the groove wall of the rectangular groove 119;

[0051] It should be noted that the setting of the adjustment handle 132 can facilitate the rotation adjustment of the cylinder 127. The surface of the connecting ring can be marked with scales, and the movable rod 130 can point to the scales marked on the surface of the connecting ring, so that the staff can clearly know the size of the adjusted sieve hole during the adjustment process; the setting of the connecting spring allows the adjustment handle 132 to move in a direction away from the first sieve plate 16 during the rotation adjustment process, that is, in the process of adjusting the misalignment of the holes on the surface of the first sieve plate 16 and the holes on the surface of the second sieve plate 17, the movement of the second sieve plate 17 will not affect the rotation of the adjustment handle 132;

[0052] It should be noted that the suction mechanism is similar in structure to the suction device used in the existing self-priming feed crushing and mixing machine, including a suction pipe, a suction impeller and a casing, and the working principle is the same, which will not be elaborated here. A controller can be installed on the surface of the mounting plate 618, and the suction mechanism and the first motor 2 are electrically connected to the controller, and the controller is controlled by a computer.
