Description

Technical Field

[0001] This invention belongs to the field of water-soluble fertilizer production technology, and specifically relates to a material mixer for water-soluble fertilizer production. Background Technology

[0002] In the production of water-soluble fertilizers, most equipment integrates crushing or grinding mechanisms to pulverize raw materials that have formed pseudo-clumps or ribbon-like animal and plant fibers due to moisture absorption, achieving a fineness of 80-100 mesh to ensure rapid and complete dissolution of the finished product. Currently, the pretreatment of such flaky or lumpy materials still largely relies on manual operation in most production stages. Operators must manually move the flaky or lumpy raw materials to the side of the crushing equipment and feed them into the crusher's inlet. During this process, it is often necessary to manually push or adjust the material's position to overcome problems such as material jamming or poor feeding. Because the edges of flaky materials are often sharp, and lumpy materials may have irregular edges, manual pushing can easily scratch gloves or even cut the palms. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a material mixer for water-soluble fertilizer production, which can ensure convenient feeding while providing a certain degree of protection for human fingers and ensuring the safety performance of the device during use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses a material mixer for water-soluble fertilizer production, comprising a housing, a crushing assembly and a guiding assembly disposed within the housing. The housing has an inlet, the guiding assembly is located at the inlet, and the crushing assembly is located below the guiding assembly. The guiding assembly includes a driving roller, a driven roller parallel to and spaced apart from the guiding assembly, and a motor for driving the driving roller. The driving roller is rotatably connected to the housing. A limit support is installed on the housing, and the upper side of the limit support has an arc-shaped limiting groove for limiting the driven roller, facing away from the driving roller. The driven roller is equipped with a transverse pre-tensioning assembly on one side of the driven roller. Two sets of transverse sliding limit frames are provided on the inner side of the housing. The two ends of the driven roller are installed in the two sets of transverse sliding limit frames. A braking assembly is also connected to the driven roller. When a human finger is clamped between the driven roller and the driven roller, it can drive the driven roller to slide down from the arc-shaped limit groove. The transverse pre-tensioning assembly drives the driven roller and its connected braking assembly to slide along the transverse sliding limit frames. After displacement, the braking assembly acts on the driven roller to stop its rotation.

[0005] Furthermore, the braking assembly includes a first rotating sleeve, a first gear, a second gear, and a bracket. The first gear is coaxially connected to the drive transmission roller. The first rotating sleeve is rotatably engaged with the driven transmission roller. The first rotating sleeve is also fixedly connected to the second gear through the bracket. When the second gear meshes with the first gear, it can stop the first gear from rotating.

[0006] Furthermore, the transverse pretensioning assembly includes an end plate, a first connecting rod, and a first spring. The end plate is connected to the first rotating sleeve via the first connecting rod. The first spring is arranged transversely, with one end of the first spring connected to the end plate and the other end of the first spring fixedly connected to the housing.

[0007] Furthermore, a vertical pre-tensioning assembly is provided between the driven transmission roller and the housing. The vertical pre-tensioning assembly includes a second rotating sleeve, a second connecting rod, and a second spring. The second rotating sleeve is rotatably engaged with the driven transmission roller. The second spring is arranged vertically. The upper end of the second spring is connected to the second rotating sleeve through the second connecting rod, and the lower end of the second spring is connected to the housing.

[0008] Furthermore, a horizontal sliding groove and a vertical locking groove are formed on the inner side of the horizontal sliding limit frame, with the vertical locking groove located at the end of the horizontal sliding groove.

[0009] Furthermore, a third gear is coaxially connected to the driven transmission roller, and in the working state, the third gear meshes with the first gear.

[0010] Furthermore, a number of flexible protective rings are evenly spaced on the driven transmission roller. A coil spring is safely placed between the inner side of the flexible protective ring and the driven transmission roller. A first limiting plate and a second limiting plate are respectively provided on both sides of the flexible protective ring. The first limiting plate and the second limiting plate are coaxially and fixedly connected to the driven transmission roller.

[0011] Furthermore, a sensing device is provided on the transverse sliding limit frame, and a first protective net and a second protective net are provided at the outlet of the material guiding component. Both the first and second protective nets include protective connecting rods evenly spaced along the longitudinal direction, a connecting shaft connecting the protective connecting rods together, and a pivot. The protective connecting rods are L-shaped, and the ends of each protective connecting rod away from the outlet of the material guiding component are connected together by the connecting shaft. The middle parts of the protective connecting rods are connected together by the pivot, which is rotatably connected to the housing. The connecting shaft is also connected to a telescopic device. The protective connecting rods of the first and second protective nets are arranged in a staggered manner. A limiting shaft for limiting the protective connecting rods of the second protective net is also connected between the protective connecting rods of the first protective net. When the sensing device receives a signal, the controller can drive the telescopic device to extend or retract. The first and second protective nets intersect each other.

[0012] The beneficial effects of this invention are as follows: This invention discloses a material mixer for water-soluble fertilizer production. The material guiding component includes an active drive roller and a driven drive roller arranged parallel to and spaced apart from the material guiding component. The width between the two is less than the width of a finger. If a human finger gets caught between the active and driven drive rollers, the finger, driven by its own action or by the body's conditioned reflex, can cause the driven drive roller to slide off the arc-shaped limiting groove. At this time, the lateral pre-tensioning component breaks through the limitation of the limiting support and can drive the driven drive roller and its connected braking component to move, thereby acting on the active drive roller to stop its rotation. This prevents potential damage to the finger from the subsequent continuous action of the device, providing a certain degree of protection for the human finger and ensuring the safety performance of the device during use.

[0013] In the device of this invention, the human finger only serves to trigger the switch, and the braking ability is mainly achieved through the braking component. Therefore, the direct force on the finger can be reduced, and damage to the finger can be avoided.

[0014] In the device of this invention, the active drive roller is directly acted on mechanically, which is more reliable than the existing electronic control method and can improve the protective stability of the device. Attached Figure Description

[0017] like Figures 1-5 As shown, this invention discloses a material mixer for water-soluble fertilizer production, comprising a housing 1, a crushing component 2 and a guiding component 3 disposed within the housing 1. The housing 1 has an inlet 4, and a stirring device can be installed inside the housing 1 for convenient mixing of various materials. The guiding component 3 is located at the inlet 4, and the crushing component 2 is located below the guiding component 3. The housing 1 is generally square, and the width of the inlet 4 is only 10mm~30mm, facilitating material input. After being input through the inlet 4, the material enters the guiding component 3, and then enters the crushing component 2 for crushing, thus achieving the function of crushing. The crushing component 2 of this invention includes a first roller cutter, a second roller cutter, a first drive shaft connected to the first roller cutter, a fourth gear fixedly connected to the first drive shaft, a second drive shaft connected to the second roller cutter, a fifth gear fixedly connected to the second drive shaft, and a motor driving the second drive shaft to rotate. The first and second roller cutters are arranged alternately, and both the first and second drive shafts are rotatably connected to the housing 1. The fourth and fifth gears mesh. The motor can drive the second drive shaft, which in turn drives the first drive shaft to rotate through the meshing of the fourth and fifth gears. When the crushed material passes between the first and second roller cutters, it can be crushed, and the crushed material is mixed and stored through the lower part of the housing 1.

[0018] Specifically, the material guiding assembly 3 of the present invention includes an active drive roller 5, a driven drive roller 6 arranged parallel to and spaced apart from the material guiding assembly 3, and a motor for driving the active drive roller 5 to rotate. Both the active drive roller 5 and the driven drive roller 6 are arranged longitudinally. The active drive roller 5 is rotatably connected to the housing 1, and the motor is fixed to the surface of the housing 1. The output shaft is connected to the active drive roller 5 to drive its rotation. The longitudinal direction referred to in the present invention refers to the axial direction of the active drive roller 5 and the driven drive roller 6, and the corresponding mutually perpendicular direction is the transverse direction.

[0019] A limiting support 7 is installed on the housing 1. The limiting support 7 is arranged vertically, and an arc-shaped limiting groove 8 is opened on the upper side of the limiting support 7 for limiting the driven drive roller 6. Under normal circumstances, the driven drive roller 6 rests in the arc-shaped limiting groove 8. A transverse pretensioning component 9 is installed on the side of the driven drive roller 6 away from the driving drive roller 5. The transverse pretensioning component 9 provides a pretensioning force to the driven drive roller 6 away from the driving drive roller 5.

[0020] Two sets of transverse sliding limit frames 10 are provided on the inner side of the housing 1. The two ends of the driven transmission roller 6 are installed in the two sets of transverse sliding limit frames 10 to limit the sliding of the driven transmission roller 6. A braking assembly 11 is also connected to the driven transmission roller 6. When a human finger is clamped between the driving transmission roller 5 and the driven transmission roller 6, it can drive the driven transmission roller 6 to slide down from the arc-shaped limit groove 8. At this time, the transverse pre-tension assembly 9 breaks through the limitation of the limit support 7 and can drive the driven transmission roller 6 and its connected braking assembly 11 to move. The transverse pre-tension assembly 9 drives the driven transmission roller 6 and its connected braking assembly 11 to slide along the transverse sliding limit frame 10. After displacement, the braking assembly 11 acts on the driving transmission roller 5 to stop its rotation.

[0021] In this embodiment, the braking assembly 11 includes a first rotating sleeve 12, a first gear 13, a second gear 14, and a bracket 15. The first gear 13 is coaxially connected to the active transmission roller 5. The first rotating sleeve 12 rotates with the driven transmission roller 6 without restricting the rotation of the driven transmission roller 6 itself. The outer side of the first rotating sleeve 12 is also fixedly connected to the second gear 14 through the bracket 15. The second gear 14 is relatively fixed. When the second gear 14 approaches the first gear 13 under the movement of the driven transmission roller 6, the second gear 14 meshes with the first gear 13, which can stop the rotation of the first gear 13, thereby achieving the braking effect. The active transmission roller 5 is braked and stopped by mechanical means, preventing the continuous entanglement of the finger. Compared with the existing electronic control method, this is more reliable and can improve the protective stability of the device.

[0022] In this embodiment, the transverse pretensioning assembly 9 includes an end plate 16, a first connecting rod 17, and a first spring 18. The first connecting rod 17 is arranged transversely and extends along the side opposite to the location of the drive roller 5. The end plate 16 is connected to the first rotating sleeve 12 through the first connecting rod 17. The first spring 18 is arranged transversely, with one end connected to the end plate 16 and the other end fixedly connected to the housing 1. The elastic force of the first spring 18 is greater than that of the second spring 22, which only provides a small pretensioning force.

[0023] In this embodiment, a vertical pre-tensioning assembly 19 is also provided between the driven transmission roller 6 and the housing 1. The vertical pre-tensioning assembly 19 is used to provide a small downward pre-tensioning force to the driven transmission roller 6. The vertical pre-tensioning assembly 19 includes a second rotating sleeve 20, a second connecting rod 21, and a second spring 22. The second rotating sleeve 20 rotates with the driven transmission roller 6 without affecting the rotation effect of the driven transmission roller 6 itself. The second spring 22 is arranged vertically. The upper end of the second spring 22 is connected to the second rotating sleeve 20 through the second connecting rod 21, and the lower end of the second spring 22 is connected to the housing 1. The second spring 22 provides a downward elastic force to the driven transmission roller 6 through the second rotating sleeve 20. By providing the vertical pre-tensioning assembly 19, the driven transmission roller 6 can be limited in the arc-shaped limiting groove 8, making the device more stable during operation.

[0024] In this embodiment, a horizontal sliding groove 23 and a vertical slot 24 are formed on the inner side of the horizontal sliding limit frame 10. The vertical slot 24 is located at the end of the horizontal sliding groove 23. When the driven transmission roller 6 moves horizontally and enters the vertical slot 24, it can limit the driven transmission roller 6 to prevent it from rebounding forward, making the operation of the device more stable. When it is needed to be used again, the driven transmission roller 6 needs to be removed from the vertical slot 24.

[0025] In this embodiment, a third gear 25 is coaxially connected to the driven transmission roller 6. In the working state, the third gear 25 meshes with the first gear 13. When the driving transmission roller 5 rotates, it can simultaneously drive the driven transmission roller 6 to rotate.

[0026] In this embodiment, a plurality of flexible protective rings 26 are evenly spaced on the driven transmission roller 6. A coil spring 27 is securely connected between the inner side of the flexible protective ring 26 and the driven transmission roller 6. A first limiting plate 28 and a second limiting plate 29 are respectively provided on both sides of the flexible protective ring 26. The first limiting plate 28 and the second limiting plate 29 are coaxially and fixedly connected to the driven transmission roller 6. By setting the flexible protective rings 26, a gap is formed between two adjacent flexible protective rings 26 for fingers to pass through. Even if the first spring 18 fails, fingers can slide into the gap to avoid danger, achieving a certain protective effect. At the same time, the cooperation between the flexible protective rings 26 and the active transmission roller 5 will not affect the material conveying.

[0027] In this invention, by providing a coil spring 27 between the flexible protective ring 26 and the driven transmission roller 6, the flexible protective ring 26 can be displaced radially relative to the driven transmission roller 6 to a certain extent. When the strip material gets stuck in the crushing assembly 2 or the guiding assembly 3, the material can be repeatedly pulled radially, allowing the flexible protective ring 26 to move radially to make way, thus facilitating the smooth removal of the material. At the same time, the coil spring 27 allows the flexible protective ring 26 to smoothly return to its original position without affecting the subsequent material conveying.

[0028] In this embodiment, a sensing device is provided on the transverse sliding limit frame 10. The sensing device is a pressure sensor installed in the vertical slot 24. When the driven transmission roller 6 moves laterally and enters the vertical slot 24, it can act on the pressure sensor. A first protective net 30 and a second protective net 31 are provided at the outlet of the material guiding assembly 3. The area between the first protective net 30 and the second protective net 31 is used for material passage, and the outer surfaces of the first protective net 30 and the second protective net 31 are used to guide the material so that the material can smoothly enter the crushing assembly 2.

[0029] The first protective net 30 and the second protective net 31 both include protective connecting rods 32 evenly spaced longitudinally, a connecting shaft 33 connecting the protective connecting rods 32 together, and a pivot 34. The protective connecting rods 32 are L-shaped. The ends of each protective connecting rod 32 away from the outlet of the material guiding component 3 are connected together by the connecting shaft 33, and the middle parts of the protective connecting rods 32 are connected together by the pivot 34. The pivot 34 is rotatably connected to the housing 1. The connecting shaft 33 is also connected to a telescopic device 35. The protective connecting rods 32 of the first protective net 30 and the second protective net 31 The first protective net 30 and the second protective net 31 are arranged in a staggered pattern. The protective rods 32 of the first protective net 30 are also connected to a limiting shaft 36 for limiting the protective rods 32 of the second protective net 31. The sensing device receives the pressure signal and transmits the signal to the controller. The controller can drive the telescopic device 35 to extend and retract, so that the first protective net 30 and the second protective net 31 deflect. The first protective net 30 and the second protective net 31 cross each other to form a protective net, which is used to block the fingers above the fragment assembly 2 and prevent the fragment assembly 2 from causing damage to the fingers.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
