Description

Technical Field

[0001] The present invention relates to the technical field of soil processing equipment, and particularly to a soil crushing and mixing machine. Background Art

[0002] In the development process of modern agriculture, the drug-free production (or less pesticide treatment production) of crops has become an important trend in the industry. In this process, the healthy cultivation of natural enemy insects is crucial, and a suitable soil environment is the key factor to ensure the high survival rate growth of insects. Indicators such as the temperature, humidity, and looseness of the soil have a profound impact on the growth and development of insects.

[0003] Currently, the existing soil crushing and mixing equipment on the market exposes many limitations in practical applications. From the perspective of the mixing effect, the mixing structure design of most equipment is not scientific and reasonable enough. Most of them are configured with a single mixing shaft and mixing rod, resulting in the soil not being fully broken and mixed during the mixing process, unable to reach the ideal degree of fine crushing and looseness, and thus unable to provide a high-quality growth environment for natural enemy insects.

[0004] At the same time, in the discharging link, the traditional mixer also has obvious deficiencies. Its discharging port lacks an effective precise control structure, making it difficult to flexibly adjust the discharging speed and discharging volume according to actual needs, which is extremely inconvenient in actual operation.

[0005] In addition, regarding the control of the landing point of the soil after mixing, the existing equipment generally lacks effective means. Since most of the discharging ports of the existing mixers are fixed, during the collection process, the soil can only fall at a fixed position in the collection box, often resulting in uneven distribution of the soil in the collection box, excessive accumulation in the landing area, and insufficient collection in other areas. This not only affects the space utilization rate of the collection box, reduces the collection efficiency, but also brings many inconveniences to the subsequent use and treatment of the soil.

[0006] Therefore, it is necessary to design a soil crushing and mixing machine to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose a soil crushing and mixing machine. This mixer can not only better crush and mix the soil, but also facilitate the discharging of the soil after mixing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0021] Referring to Figures 1-5 , a soil crushing mixer includes a material box 1 and a top cover 2. A crushing and stirring assembly is provided inside the material box 1. The crushing and stirring assembly includes two stirring shafts 8 rotatably connected to the inner walls on the left and right sides of the material box 1. The setting of these two stirring shafts 8 is to achieve a more sufficient stirring effect on the soil. Double-shaft stirring can increase the contact area and stirring path between the soil and the stirring components, thereby improving the uniformity and efficiency of stirring. A plurality of blades 9 are fixedly connected to the outer walls of the two stirring shafts 8 along their axial directions. These blades 9 are distributed along the axial direction of the stirring shafts 8, and their special structural design, such as being twisted and intersecting each other, can not only avoid the collision between the blades 9 during the stirring process, but also effectively convey the soil during rotation, assisting in controlling the discharging speed. During the stirring process, the twisted shape of the blades 9 causes the soil to receive a combined force along the axial and radial directions when contacting the blades 9. The force along the axial direction pushes the soil to move in the direction of the stirring shaft 8, while the radial force causes the soil to move in a circular motion inside the material box 1. The blades 9 cross-set on the two stirring shafts 8 cooperate with each other. When the stirring shafts 8 rotate, the blades 9 on one stirring shaft 8 push the soil to move to one side, and the blades 9 on the other stirring shaft 8 bring the soil back from the other side, forming a circulating flow. This circulating flow not only enhances the stirring effect, but also makes the soil gradually convey towards the discharging port 10 while being stirred. When the stirring is approaching the end, the rotation speed of the stirring shafts 8 can be appropriately adjusted, and by using the conveying effect of the blades 9, the stirred soil can be more efficiently pushed towards the discharging port to achieve the control of the discharging speed. The right sides of the two stirring shafts 8 both extend to the outside and are fixedly connected with first gears 23. A protective cover 19 is fixedly connected to the right side of the material box 1. The two first gears 23 are located inside the protective cover 19. The setting of the protective cover 19 can effectively prevent foreign objects from entering the outside, avoid the interference between the foreign objects and the first gears 23, affect the normal meshing of the gears and the operation of the mixer, and play a role in protecting the key components of the equipment. A speed reducer 7 is installed on the left side of the material box 1. The speed reducer 7 can perform speed reduction and torque increase processing on the power input by the driving motor 6, so that the stirring shafts 8 obtain appropriate rotation speed and torque to meet the requirements of soil crushing and stirring work. The output shaft of the speed reducer 7 is fixedly connected to the stirring shaft 8 located at the rear side. A driving motor 6 is installed on the left side of the speed reducer 7. The end of the output shaft of the driving motor 6 is fixedly connected to the input shaft of the speed reducer 7. The material box 1 and the top cover 2 are rotatably connected through two hinges. Two rectangular grooves 5 are provided at the upper end of the material box 1. The front inner walls of the two rectangular grooves 5 are both rotatably connected with hydraulic cylinders 4. The telescopic ends of the two hydraulic cylinders 4 are rotatably connected to the front side of the material box 1. Through the telescopic action of the hydraulic cylinders 4, the opening and closing control of the top cover 2 can be realized.

[0022] Among them, a feed port 3 is provided on the top cover 2, and the feed port 3 is provided to facilitate pouring the soil to be mixed into the material box 1. A discharge port 10 is provided at the inner bottom of the material box 1, and a strip block 37 is fixedly connected to the lower end of the material box 1. Two pneumatic rods 38 are fixedly connected to the right side of the strip block 37, and the telescopic ends of the two pneumatic rods 38 are fixedly connected to a baffle 39 that matches the discharge port 10.

[0023] Among them, the lower end of the material box 1 is fixedly connected with a plurality of support rods 18, and the adjacent sides of the two support rods 18 located on the right side are commonly fixedly connected with a discharge hopper 20. When discharging, a collection box is placed on the right side of the device. The discharge hopper 20 is used to receive the soil discharged from the discharge port 10 and guide the soil to flow to the collection box. The design of its position and shape is conducive to the smooth outflow and collection of the soil. The adjacent sides of the two support rods 18 located on the right side are commonly fixedly connected with a fixed plate 22, and a swing assembly is provided on the fixed plate 22. The swing assembly is used to control the landing point of the processed soil so that the processed soil is evenly distributed in the collection box. The swing assembly includes a vertical rod 24 that is rotatably connected to the fixed plate 22. The upper end of the vertical rod 24 is fixedly connected with a support frame 29. The inner walls of the front and rear sides of the support frame 29 are commonly fixedly connected with a rotating rod 30. The rotating rod 30 is fixedly connected with an inclined plate 21. The left area of ​​the inclined plate 21 is located directly below the discharge hopper 20. The vertical rod 24 is connected to the fixed plate 22. The torsion spring 28 is elastically connected, and the elastic connection of the torsion spring 28 provides a restoring force for the rotation of the vertical rod 24, so that the vertical rod 24 can return to its original position under the action of the torsion spring 28 after being rotated by an external force, thereby ensuring the normal operation and stable operation of the swing assembly. The left side of the material box 1 is fixedly connected with a mounting block 12, and a reciprocating screw rod 15 is rotatably connected through the mounting block 12. The left side of the stirring shaft 8 located on the front side extends to the outside world. The reciprocating screw rod 15 and the stirring shaft 8 are both provided with mutually meshing bevel gears 11. A transmission rod 25 is rotatably connected through the fixed plate 22. The transmission rod 25 and the reciprocating screw rod 15 are connected to each other through a transmission assembly 17. An incomplete gear 26 is provided on the transmission rod 25, and a second gear 27 is provided on the vertical rod 24. The incomplete gear 26 meshes with the second gear 27 on the vertical rod 24. Through its special structural design, intermittent meshing transmission can be achieved, so that the vertical rod 24 produces periodic rotation, thereby driving the inclined plate 21 to swing.

[0024] Among them, it also includes an angle adjustment component, which is used to adjust the inclination angle of the inclined plate 21 so that the soil can form different landing points in the collection box. The angle adjustment component includes a rectangular box 31 fixedly connected to the front side of the support frame 29. The front side of the rotating rod 30 extends into the rectangular box 31. A third gear 33 is provided on the rotating rod 30. An electromagnet 34 is embedded in the right inner wall of the rectangular box 31. A moving block 35 is slidably connected in the rectangular box 31. The adjacent side of the moving block 35 and the electromagnet 34 is elastically connected by a spring 36. A rack 32 is fixedly connected to the left side of the moving block 35. The rack 32 meshes with the third gear 33. The third gear 33 meshes with the rack 32. Under the action of the electromagnet 34 and the moving block 35, the rotation of the third gear 33 is driven by the movement of the rack 32, thereby realizing the rotation of the rotating rod 30 and adjusting the inclination angle of the inclined plate 21. The spring 36 provides a restoring force for the moving block 35. When the electromagnet 34 is powered off or its magnetism weakens, the spring 36 can make the moving block 35 return to its original position, ensuring the stability and repeatability of the angle adjustment component.

[0025] Among them, a control box 13 is fixedly connected to the lower end of the mounting block 12. The reciprocating lead screw 15 passes through the control box 13. A conductive plate 14 is threadedly connected to the reciprocating lead screw 15. The conductive plate 14 is slidably connected to the inner wall of the control box 13. A copper bar 16 is fixedly connected to the common top and bottom of the inner part of the control box 13. The copper bar 16 passes through the conductive plate 14. The conductive plate 14 is slidably connected to the copper bar 16. The copper bar 16, as a part of the circuit, cooperates with the conductive plate 14 to form a sliding rheostat. By sliding the conductive plate 14 on the copper bar 16, the resistance value in the circuit is changed, thereby realizing the control of the current of the electromagnet 34. A power supply is provided on the material box 1. The positive pole of the power supply is electrically connected to the lower end of the copper bar 16 through a wire. The electromagnet 34 is electrically connected to the conductive plate 14 through a wire. The other end of the electromagnet 34 is electrically connected to the negative pole of the power supply through a wire.

[0026] The functional principle of the present invention can be described by the following operation method: After the power supply is turned on, the control drive motor 6 is started. Its output shaft rotates and transmits power to the reduction gearbox 7. After the reduction gearbox 7 reduces the speed and increases the torque of the power, the power is transmitted to the stirring shaft 8 at the rear side. Since the first gears 23 on the right sides of the two stirring shafts 8 mesh with each other, when the rear stirring shaft 8 rotates, it will drive the front stirring shaft 8 to rotate synchronously.

[0027] According to the set program, the two stirring shafts 8 start to stir towards each other. After rotating forward at a certain speed for a certain period of time, they automatically reverse and continue for a period of time, and then rotate forward again to crush and stir for a period of time. During this process, the multiple twisted and mutually crossed blades 9 fixedly connected along the axial direction on the two stirring shafts 8 rotate accordingly, fully crushing and mixing the soil in the material box 1. The special structure of the blades 9 can not only avoid mutual collision but also convey the soil during rotation, realizing efficient stirring treatment of the soil, making it reach the ideal degree of fine crushing and looseness, and providing a good growth environment for natural enemy insects. After the stirring is completed, the mixed soil is gradually pushed towards the discharge port 10 while stirring.

[0028] Determine whether the crushed and stirred soil can reach the ideal state of fine crushing or looseness by observation or touching. If the requirements are not met, the rotation speed or stirring time can be appropriately adjusted at this time to meet the requirements.

[0029] When the soil stirring is completed, control the pneumatic rod 38 to extend. The telescopic end of the pneumatic rod 38 drives the baffle 39 that cooperates with the discharge port 10 to move, opening the discharge port 10, and the stirred soil falls from the discharge port 10 and flows out through the discharge hopper 20. During the discharging process, the rotation of the blades 9 can also assist in controlling the discharging speed of the soil and flexibly adjusting the discharging rhythm according to actual needs.

[0030] During discharging, the drive motor 6 is still in an operating state. At this time, while the stirring shaft 8 rotates, the stirring shaft 8 located at the front side drives the bevel gear 11 meshed with it to rotate, thereby making the reciprocating lead screw 15 rotate. The reciprocating lead screw 15 transmits power to the transmission rod 25 through the transmission assembly 17, making the transmission rod 25 rotate. The incomplete gear 26 on the transmission rod 25 meshes with the second gear 27 on the vertical rod 24, driving the vertical rod 24 to rotate. The vertical rod 24 and the fixed plate 22 are elastically connected by a torsion spring 28. Under the intermittent meshing action of the incomplete gear 26 and the second gear 27, the vertical rod 24 drives the support frame 29, the rotating rod 30, and the inclined plate 21 to swing, making the landing point of the soil falling from the discharge hopper 20 arc-shaped and evenly distributed in the collection box, improving the space utilization rate and collection efficiency of the collection box.

[0031] As the reciprocating lead screw 15 rotates, the conductive plate 14 threadedly connected to the reciprocating lead screw 15 moves axially along the reciprocating lead screw 15 within the control box 13. As the reciprocating lead screw 15 rotates, the conductive plate 14 threadedly connected to the reciprocating lead screw 15 moves axially along the reciprocating lead screw 15 within the control box 13. A sliding rheostat is formed between the conductive plate 14 and the copper bar 16. When the conductive plate 14 moves downward, the resistance connected to the circuit decreases. According to Ohm's law, the current passing through the electromagnet 34 increases, and the magnetism generated by the electromagnet 34 enhances, attracting the moving block 35 to move rightward. The rack 32 on the left side of the moving block 35 meshes with the third gear 33 on the rotating rod 30. The movement of the rack 32 drives the third gear 33 to rotate, and then the rotating rod 30 rotates, causing the inclined plate 21 to rotate downward to adjust the inclination angle of the inclined plate 21.

[0032] When the conductive plate 14 moves upward, the resistance connected to the circuit increases, the current passing through the electromagnet 34 decreases, and the magnetism of the electromagnet 34 weakens. Under the action of the spring 36, the moving block 35 moves leftward, and the rack 32 disengages from the third gear 33 or acts in the reverse direction, enabling the inclined plate 21 to rotate upward. By changing the inclination angle of the inclined plate 21 in this way, different landing points of the soil are formed within the collection box, further realizing a more uniform distribution of the soil within the collection box, providing greater convenience for the subsequent use and treatment of the soil.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
