Description

Technical Field

[0001] The present invention relates to the technical field of straw dehydration, and specifically provides a straw dehydration device for soil fertilizer processing. Background Art

[0002] Straw is the general term for the stems and leaves of mature crops. Its common use is to improve soil fertility as fertilizer. Before using straw as fertilizer, it usually needs to be crushed and dehydrated. Crushing helps reduce the volume of straw and improve the dehydration efficiency; while dehydration helps remove excess moisture and improve the stability and fertilizer efficiency of the fertilizer.

[0003] Currently, common dehydration methods in rural areas are to use solar energy and wind energy to evaporate the moisture in straw. It only requires spreading the straw on a flat ground, turning it over appropriately, and continuously drying it until the required moisture content is reached. Although it is simple and easy to operate, it is limited by weather conditions and the dehydration effect is slow.

[0004] To solve the above problems, we made improvements and proposed a straw dehydration device for soil fertilizer processing. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] The present invention provides a straw dehydration device for soil fertilizer processing, including a bottom plate.

An annular sliding groove is formed on the outer wall of the circular plate, and the support ring is located inside the annular sliding groove of the circular plate. On the top surface of the circular plate, a dehydration cylinder is coaxially and fixedly connected.

The other end of the rectangular sliding rod is fixedly connected to a baffle, and a spring is fixedly connected between the baffle and the inner wall of the housing;

[0009] The top surface of the bottom plate is fixedly connected to a sealing cylinder. An air outlet pipe is communicated between the lower part of the sealing cylinder and the side surface of the housing. The lower part of the sealing cylinder is also communicated with an air inlet pipe. One-way valves are installed on both the air outlet pipe and the air inlet pipe.

A connecting rod is hinged to the side surface of the spur gear, and the top end of the piston rod extending through the outside of the sealing cylinder is hinged to the bottom end of the connecting rod.

[0010] As a preferred technical solution of the present invention, the dehydration cylinder includes an outer cylinder and an inner cylinder. A plurality of filter holes are uniformly formed on the inner wall of the inner cylinder. A cavity is formed at the bottom of the inner cylinder. A plurality of air outlet holes communicating with the cavity are formed on the inner bottom surface of the inner cylinder, and one-way valves are installed inside the air outlet holes.

[0011] As a preferred technical solution of the present invention, a first motor is fixedly installed on the other side surface of the vertical plate. The output shaft of the first motor is coaxially and fixedly connected to the first rotating rod.

[0012] As a preferred technical solution of the present invention, the other side of the housing is communicated with a hot air conveying pipe. The hot air conveying pipe penetrates through the circular plate and is communicated with the cavity at the bottom of the inner cylinder through a sealed rotary joint.

The output shaft of the second motor is coaxially and fixedly connected to the rotating shaft of the first driving pulley. A first driven pulley is coaxially and fixedly connected to the bottom surface of the circular plate, and the hot air conveying pipe penetrates through the first driven pulley.

The first motor is started through an external controller. The first motor drives the first rotating rod to rotate, and the first rotating rod drives the spur gear to rotate. Since the spur gear meshes with the rack, the spur gear will drive the L-shaped movable plate to move downward along the direction of the rectangular limiting plate, further driving the pressing rod and the circular pressing plate to move downward, squeezing and dehydrating the straw inside the dehydration cylinder. Compared with using solar energy and wind energy for straw dehydration, this dehydration device is not restricted by weather conditions and has a faster dehydration effect.

[0019] Second, for this straw dehydration device for soil fertilizer processing, the second motor is started through an external controller. The second motor drives the first driving pulley to rotate. The first driving pulley drives the first driven pulley to rotate through the transmission belt. The circular plate rotates synchronously with the first driven pulley, further driving the dehydration cylinder to rotate, and using centrifugal force to accelerate straw dehydration.

[0020] Third, for this straw dehydration device for soil fertilizer processing, the second rotating rod rotates synchronously, driving the friction disc to rotate. Heat is generated by the friction between the friction disc and the friction block, heating the air inside the housing. And the piston rod is driven to move up and down through the connecting rod, further driving the piston to move up and down. When the piston moves up, the outside air is drawn into the inside of the sealing cylinder through the air inlet pipe. When the piston moves down, the air inside the sealing cylinder enters the inside of the housing through the air outlet pipe. After heating, finally, it enters the cavity of the inner cylinder of the dehydration cylinder through the hot air delivery pipe, and the hot air is discharged into the inside of the inner cylinder through the air outlet holes, drying the straw and further accelerating straw dehydration.

[0031] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0032] Embodiment: As Figure 1As shown in the figure, a straw dehydration device for soil fertilizer processing includes a bottom plate 1. Two L-shaped support plates 2 are symmetrically and fixedly connected to the top surface of the bottom plate 1. A support ring 3 is fixedly connected between the two L-shaped support plates 2. The inner wall of the support ring 3 is coaxially and rotatably connected to a circular plate 4. An annular chute is provided on the outer wall of the circular plate 4, and the support ring 3 is located inside the annular chute of the circular plate 4. A dehydration cylinder 5 is coaxially and fixedly connected to the top surface of the circular plate 4, and the dehydration cylinder 5 can rotate synchronously with the circular plate 4;

[0033] A rectangular limiting plate 6 is fixedly connected to the top surface of the bottom plate 1. An L-shaped movable plate 7 is slidably connected to the outer wall of the rectangular limiting plate 6. A pressing rod 8 is installed on the inner top surface of the L-shaped movable plate 7. The bottom end of the pressing rod 8 is rotatably connected to a circular pressing plate 9 located directly above the dehydration cylinder 5. A rack 10 is fixedly connected to the outer side surface of the L-shaped movable plate 7. A vertical plate 11 is also fixedly connected to the bottom surface of the bottom plate 1. A first rotating rod 12 is rotatably connected to the side surface of the vertical plate 11. A spur gear 13 meshing with the rack 10 is coaxially and fixedly connected to the end of the first rotating rod 12;

[0034] A first motor 20 is fixedly installed on the other side surface of the vertical plate 11. The output shaft of the first motor 20 is coaxially and fixedly connected to the first rotating rod 12. It should be noted that the first motor 20 needs to be electrically connected to an external controller.

[0035] As Figure 1 shown, the straw crushed by a crusher is placed in the dehydration cylinder 5. The first motor 20 is started through an external controller. The first motor 20 drives the first rotating rod 12 to rotate. The first rotating rod 12 drives the spur gear 13 to rotate. Since the spur gear 13 meshes with the rack 10, the spur gear 13 will drive the L-shaped movable plate 7 to move downward along the direction of the rectangular limiting plate 6, further driving the pressing rod 8 and the circular pressing plate 9 to move downward, and squeezing and dehydrating the straw inside the dehydration cylinder 5.

[0036] As Figure 4 and Figure 5 shown, a portal support plate 28 is fixedly connected to the top surface of the bottom plate 1. A first driving pulley 29 is rotatably connected to the top surface of the portal support plate 28. A second motor 30 is fixedly installed on the inner top surface of the portal support plate 28. The output shaft of the second motor 30 is coaxially and fixedly connected to the rotating shaft of the first driving pulley 29. A first driven pulley 31 is coaxially and fixedly connected to the bottom surface of the circular plate 4, and the hot gas delivery pipe 26 passes through the first driven pulley 31. The first driving pulley 29 and the first driven pulley 31 are driven by a transmission belt. It should be noted that the second motor 30 needs to be electrically connected to an external controller.

[0037] The second motor 30 is started by an external controller. The second motor 30 drives the first driving pulley 29 to rotate. The first driving pulley 29 drives the first driven pulley 31 to rotate through a transmission belt. The circular plate 4 rotates synchronously with the first driven pulley 31, further driving the dewatering cylinder 5 to rotate, and using centrifugal force to accelerate the dewatering of the straw.

[0038] As Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, a heating mechanism is provided between the bottom plate 1 and the circular plate 4. The heating mechanism includes a housing 14. A fixing plate is fixedly connected between the outer wall of the housing 14 and the top surface of the bottom plate 1. An installation cylinder 15 is horizontally and fixedly connected inside the housing 14. A friction disc 16 is coaxially arranged inside the installation cylinder 15. A second rotating rod 17 is rotatably connected to the side of the housing 14. One end of the second rotating rod 17 located inside the housing 14 is coaxially and fixedly connected to the friction disc 16. A plurality of rectangular sliding rods distributed in a circumferential array are slidably connected to the outer wall of the installation cylinder 15. One end of the rectangular sliding rod located inside the installation cylinder 15 is fixedly connected with a friction block 18 in contact with the friction disc 16. The other end of the rectangular sliding rod is fixedly connected with a baffle 19, and a spring is fixedly connected between the baffle 19 and the inner wall of the housing 14.

[0039] The inner side of the portal support plate 28 is rotatably connected with a first bevel gear 32. The first bevel gear 32 meshes with a second bevel gear 33, and the second rotating rod 17 is coaxially and fixedly connected with the second bevel gear 33.

[0040] The outer side of the portal support plate 28 is rotatably connected with a second driven pulley 34. The second driven pulley 34 is coaxially and fixedly connected with the rotating shaft of the first bevel gear 32. A second driving pulley 35 is coaxially and fixedly connected to the outer wall of the first rotating rod 12. The second driving pulley 35 and the second driven pulley 34 are driven by a transmission belt.

[0041] The first motor 20 rotates, driving the second driving pulley 35 to rotate. The second driving pulley 35 drives the second driven pulley 34 to rotate through a transmission belt. The second driven pulley 34 further drives the first bevel gear 32 to rotate. The second bevel gear 33 rotates synchronously with the first bevel gear 32. The second rotating rod 17 rotates synchronously, driving the friction disc 16 to rotate. The friction between the friction disc 16 and the friction block 18 generates heat, heating the air inside the housing 14. In addition, through the cooperation among the rectangular sliding rod, the baffle 19 and the spring, the friction disc 16 and the friction block 18 are always in contact for friction.

[0042] As Figure 2 、 Figure 3 and Figure 6As shown in the figure, a sealing cylinder 21 is fixedly connected to the top surface of the bottom plate 1. An air outlet pipe 22 is connected between the lower part of the sealing cylinder 21 and the side surface of the outer shell 14. The lower part of the sealing cylinder 21 is also connected to an air inlet pipe. Check valves are installed on both the air outlet pipe 22 and the air inlet pipe. A piston 23 is slidably connected to the inner wall of the sealing cylinder 21 in a sealed manner. A piston rod 24 is fixedly connected to the top surface of the piston 23. A connecting rod 25 is hinged to the side surface of the spur gear 13. And the piston rod 24 extends through the top end outside the sealing cylinder 21 and is hinged to the bottom end of the connecting rod 25. It should be noted that the connection between the sealing cylinder 21 and the piston rod 24 is not sealed. The check valve on the air inlet pipe ensures that air can only flow into the inside of the sealing cylinder 21 from the outside, and the check valve on the air outlet pipe 22 ensures that air can only flow from the inside of the sealing cylinder 21 into the inside of the outer shell 14.

[0043] On the other side of the outer shell 14, a hot air delivery pipe 26 is connected. The hot air delivery pipe 26 passes through the circular plate 4 and is connected to the cavity at the bottom of the inner cylinder 52 through a sealed rotary joint.

[0044] When the spur gear 13 rotates, it drives the piston rod 24 to move up and down through the connecting rod 25, further driving the piston 23 to move up and down. When the piston 23 moves up, it pumps outside air into the inside of the sealing cylinder 21 through the air inlet pipe. When the piston 23 moves down, it discharges the air inside the sealing cylinder 21 into the inside of the outer shell 14 through the air outlet pipe 22. After heating, it finally enters the cavity of the inner cylinder 52 of the dehydration cylinder 5 through the hot air delivery pipe 26, and discharges the hot air into the inside of the inner cylinder 52 through the air outlet holes, drying the straw, and further accelerating the dehydration of the straw.

[0045] As Figure 5 shown, the dehydration cylinder 5 includes an outer cylinder 51 and an inner cylinder 52. A plurality of filter holes are evenly formed on the inner wall of the inner cylinder 52. A cavity is formed at the bottom of the inner cylinder 52. A plurality of air outlet holes communicating with the cavity are formed on the inner bottom surface of the inner cylinder 52, and check valves are installed inside the air outlet holes.

[0046] It should be noted that the cavity has a certain height, which can be designed according to specific needs to prevent water from flowing back into the inner cylinder 52 through the filter holes after the equipment stops running. The check valve in the air outlet hole can prevent water from flowing into the cavity of the inner cylinder 52 through the air outlet hole.

[0047] As Figure 5 shown, a water outlet pipe 27 is fixedly installed inside the circular plate 4. A valve is installed at the bottom end of the water outlet pipe 27 extending outside the circular plate 4. The top end of the water outlet pipe 27 is connected to the outer cylinder 51.

[0048] After the straw dehydration is completed, open the valve on the water outlet pipe 27, and the water inside the outer cylinder 51 can be discharged.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
