Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer spreaders, and in particular to a farmland soil fertilizer spreader for fertilizer based on conversion of kitchen solid waste. Background Art

[0002] Kitchen solid waste mainly includes leftovers, leftover rice, fruit peels, bones, etc. These substances contain a large amount of organic matter, such as carbohydrates, proteins, fats, etc. Among them, leftovers are a good matrix for the growth and reproduction of microorganisms, rich in nutrients such as nitrogen, phosphorus, and potassium; fruit peels are rich in cellulose and minerals; although bones are mainly composed of minerals such as calcium and phosphorus, they can also become effective ingredients for fertilizers after proper treatment. Therefore, converting kitchen solid waste into fertilizer is an environmentally friendly and resource-efficient way.

[0003] After the solid kitchen waste is converted into fertilizer, it needs to be landfilled into the farmland soil using a fertilizer spreader to provide fertility to the farmland soil. The fertilizer spreader is roughly divided into traction equipment, trenching equipment, storage equipment, sowing equipment and other components.

[0004] The patent with patent publication number CN116034693B discloses a fertilizer structure of a fertilizer spreader and a fertilizer spreader thereof, including a hopper, a fertilizer control component for controlling the amount of fertilizer applied is arranged at the lower side of the hopper, the fertilizer control component includes an upper box body, a first drive shaft is coaxially arranged inside the upper box body, a plurality of first baffles for blocking and shifting fertilizer are evenly arranged at equal angles on the first drive shaft, the distal end of the first baffle is in contact with the inner cavity wall of the upper box body, and the first drive shaft is upwardly movably connected with two material blocks; a fertilizer discharge component for discharging fertilizer is arranged at the lower side of the fertilizer control component, the fertilizer discharge component includes a lower box body, a second drive is coaxially arranged inside the lower box body, a second baffle less than the number of the first baffles and used for blocking and shifting fertilizer is arranged at equal angles on the second drive shaft, the distal end of the second baffle is in contact with the inner cavity wall of the lower box body, and a first transmission component is arranged between the second drive shaft and the first drive shaft for transmission. The present invention realizes quantitative and intermittent fertilization through simple features.

[0005] The prior art has the following defects: Since the fertilizer converted from food solid waste is very wet, a large amount of fertilizer is stored in the storage device when the fertilizer spreader spreads it. The wet fertilizer is pushed together for a long time and is prone to sticking and clumping, causing the fertilizer to be blocked at the outlet of the storage device and difficult to be discharged through the spreading equipment.

[0006] When a fertilizer spreader spreads fertilizer, the spreading equipment needs to use a longer pipe to transport the fertilizer into the excavated ditch. When the fertilizer is transported through the pipe, the wet fertilizer is easy to adhere to the inner wall of the pipe. After a long time, the pipe will be blocked, the fertilizer transportation will be blocked, and the fertilizer spreading will be uneven. Summary of the invention

[0007] In view of the problem in the prior art that the fertilizer has a relatively high humidity and is prone to sticking, a farmland soil fertilizer applicator for fertilizers converted from kitchen waste is proposed.

[0008] The present application provides a farmland soil fertilizer applicator for fertilizers converted from kitchen waste, and its purpose is to avoid fertilizer adhering to the storage device and the spreading device.

[0009] The technical solution of the present invention is: a farmland soil fertilizer applicator for fertilizers converted from kitchen waste, including a traction device, a traction frame arranged behind the traction device, a storage device arranged on the top of the traction frame, a trenching device arranged on the bottom of the traction frame, a spreading device arranged on the bottom of the storage device. The storage device further includes a hopper arranged on the top of the traction frame, a discharge port arranged at the bottom of the hopper, a pushing screw and an auxiliary screw arranged inside the hopper, rotating shafts arranged at both ends of the pushing screw and the auxiliary screw, and a pushing motor arranged on the top of the traction frame; The pushing screw extends out of the hopper and is connected to the pushing motor. The auxiliary screw meshes with the pushing screw. The discharge port is located below the pushing screw, and the discharge port and the trenching device are in the same plane.

[0010] Furthermore, the discharge port is located at the center of the hopper. The thread on the outside of the pushing screw is set in two sections, and the two sections of threads are respectively distributed at both ends of the pushing screw, and the spiral directions of the two sections of threads are opposite.

[0011] Furthermore, the bottom surface of the hopper is designed to be inclined and inclined towards the discharge port.

[0012] Furthermore, the storage device further includes rotating disks arranged at both ends of the auxiliary screw, fixed disks arranged on both sides of the inner wall of the hopper, sliding covers arranged on the outside of the fixed disks, pushing teeth arranged on the opposite sides of the rotating disks and the sliding covers, a striking table arranged inside the sliding cover, and guide rods arranged on the outside of the hopper; The rotating disks, the sliding covers and the fixed disks are all sleeved on the outside of the rotating shaft. The teeth of the pushing teeth are triangular, and the tips of the teeth of the two groups of pushing teeth face each other. The guide rods penetrate the fixed disks and are fixedly connected to the sliding covers. The guide rods are threadedly connected to the hopper. A return spring is installed between the guide rods and the pushing teeth. The striking table is in contact with the fixed disk.

[0013] Furthermore, the spreading device specifically includes a discharge pipe arranged at the bottom of the hopper, a ground-engaging plow head arranged at the bottom end of the discharge pipe, and a leakage outlet opened on the outside of the ground-engaging plow head; The bottom end of the discharge pipe is at the same height as the ground. The ground-engaging plow head gradually narrows towards the direction close to the traction device and is in a pointed shape. The leakage outlet is located on the side of the ground-engaging plow head away from the traction device.

[0014] Further, the spreading device further includes a rotating ring disposed inside the discharge pipe, a hanging rod disposed in a direction away from the hopper on the rotating ring, a rotating groove opened on the outer side of the rotating ring, a positioning bolt disposed outside the discharge pipe, and a driving motor disposed on the top of the traction frame; The rotating groove is annular, the positioning bolt penetrates through the discharge pipe and extends into the rotating groove, the hanging rod is attached to the inner wall of the discharge pipe, one side of the hanging rod close to the discharge pipe is triangularly designed, and a toothed groove engaged with the driving motor is opened on the outer side of the rotating ring.

[0015] Further, the hanging rods are annularly distributed below the rotating ring.

[0016] Further, the inner wall of the discharge pipe is fixedly connected with top blocks distributed in an annular array, and the top blocks and the hanging rods are staggered.

[0017] Further, one end of the hanging rod away from the hopper is provided with a mounting post, a stirring bar and a fixing cap disposed on the outer side of the mounting post; The stirring bar is made of flexible rubber, and the stirring bar extends into the ground-engaging plowshare.

[0018] Advantages of the present invention: 1. By providing a pushing screw, during the fertilization process, the pushing screw rotates, continuously stirring the fertilizer in the hopper. The pushing screw crushes the caked fertilizer and pushes the crushed fertilizer towards the discharge port through the thread, enabling the fertilizer to smoothly leave the hopper and preventing the discharge port from being blocked. At the same time, an auxiliary screw is provided. When the pushing screw rotates, it drives the auxiliary screw to rotate. The threads and screw grooves of the auxiliary screw and the pushing screw are staggered with each other. In this way, during rotation, it can prevent the fertilizer from sticking in the screw groove, resulting in a weakening of the stirring and pushing functions of the pushing screw.

[0019] 2. By providing a sliding cover and a rotating disk, when the fertilizer in the hopper is about to be exhausted, the sliding cover is pushed close to the rotating disk so that the two pushing teeth engage. In this way, when the auxiliary screw rotates, the rotating disk pushes the sliding cover to hit the fixed disk. The fixed disk is impacted and generates vibrations, and then the vibrations are transmitted to the hopper, causing the fertilizer adhering to its inner wall to fall off, avoiding the situation of fertilizer residue.

[0020] 3. By providing a storage device, the ground-engaging plowshare is buckled in the ditch dug by the ditch-opening device. During the movement, it can push aside the soil in front. The fertilizer falls along the discharge pipe and the ground-engaging plowshare and leaks out from the leakage port. In this way, it can prevent the soil from blocking the fertilizer outlet. At the same time, a hanging rod is provided. When spreading the fertilizer, the rotating ring drives the hanging rod to rotate in the discharge pipe. The hanging rod continuously stirs the fertilizer inside the discharge pipe and scrapes the inner wall of the discharge pipe, which can prevent the fertilizer from being blocked inside the discharge pipe and ensure the smooth spreading of the fertilizer.

[0021] 4. By setting the top block, the hanging rod will continuously contact the top block during rotation, causing the hanging rod to continuously deflect towards the central axis of the discharge pipe. This can prevent fertilizers from sticking between the hanging rods and further improve the dredging effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0025] Example 1, referring to Figures 1 - 3 , Figures 8 - 18 , which is the first embodiment of the present invention, provides a fertilizer application machine for farmland soil based on the conversion of kitchen waste, including a tractor 1, a tractor frame 2 arranged behind the tractor 1, a storage device 3 arranged on the top of the tractor frame 2, a ditching device 4 arranged at the bottom of the tractor frame 2, a sowing device 5 arranged at the bottom of the storage device 3. The storage device 3 further includes a hopper 31 arranged on the top of the tractor frame 2, a discharge port 32 arranged at the bottom of the hopper 31, a pushing screw 33 and an auxiliary screw 35 arranged inside the hopper 31, rotating shafts 312 arranged at both ends of the pushing screw 33 and the auxiliary screw 35, and a pushing motor 34 arranged on the top of the tractor frame 2.

[0026] Specifically, the tractor 1 can be a tractor. A landing gear is installed behind the tractor 1. The tractor frame 2 is fixed to the landing gear by bolts. The hopper 31 is fixed above the tractor frame 2 by bolts. The pushing screw 33 extends out of the hopper 31 and is connected to the pushing motor 34. The auxiliary screw 35 meshes with the pushing screw 33. The discharge port 32 is located below the pushing screw 33. The discharge port 32 and the ditching device 4 are in the same plane; the discharge port 32 is located at the center of the hopper 31. The threads on the outside of the pushing screw 33 are set in two sections, and the two sections of threads are respectively distributed at both ends of the pushing screw 33. The two sections of threads have opposite spiral directions. The discharge port 32 is located in the middle of the two sections of threads. The rotating shafts 312 are fixedly connected to the auxiliary screw 35 and the pushing screw 33. The auxiliary screw 35 and the pushing screw 33 are rotatably connected to the hopper 31 through the rotating shafts 312; the bottom surface of the hopper 31 is designed to be inclined and inclined towards the direction of the discharge port 32.

[0027] By setting the pushing screw 33, during the fertilization process, the pushing screw 33 rotates, continuously agitating the fertilizer in the hopper 31. The pushing screw 33 crushes the caked fertilizer and pushes the crushed fertilizer towards the discharge port 32 through the threads, enabling the fertilizer to smoothly leave the hopper 31 and preventing the discharge port 32 from being blocked. At the same time, an auxiliary screw 35 is set. When the pushing screw 33 rotates, it drives the auxiliary screw 35 to rotate. The threads and screw grooves of the auxiliary screw 35 and the pushing screw 33 intersect with each other. In this way, when rotating, it can prevent the fertilizer from adhering to the screw grooves, resulting in a weakened agitation and pushing function of the pushing screw 33.

[0028] The storage device 3 further includes rotating disks 36 provided at both ends of the auxiliary screw 35, fixed disks 37 provided on both sides of the inner wall of the hopper 31, sliding covers 38 provided outside the fixed disks 37, pushing teeth 39 provided on the opposite sides of the rotating disks 36 and the sliding covers 38, striking platforms 310 provided inside the sliding covers 38, and guide rods 311 provided outside the hopper 31.

[0029] Specifically, the rotating disks 36, the sliding covers 38, and the fixed disks 37 are all sleeved outside the rotating shaft 312. The rotating disks 36 are fixed to the auxiliary screw 35 by bolts, the fixed disks 37 are fixed to the inner wall of the hopper 31 by bolts, the sliding covers 38 are slidably sleeved outside the fixed disks 37. The teeth of the pushing teeth 39 are triangular, and the tips of the teeth of the two groups of pushing teeth 39 face each other. The guide rods 311 penetrate through the fixed disks 37 and are fixedly connected to the sliding covers 38. A section of thread is provided on the outside of the guide rods 311, and the guide rods 311 are threadedly connected to the hopper 31. A return spring is installed between the guide rods 311 and the pushing teeth 39, and the striking platforms 310 are in contact with the fixed disks 37.

[0030] By setting the sliding covers 38 and the rotating disks 36, when the fertilizer in the hopper 31 is about to be exhausted, the sliding covers 38 are pushed closer to the rotating disks 36, causing the two groups of pushing teeth 39 to engage. In this way, when the auxiliary screw 35 rotates, the rotating disks 36 push the sliding covers 38 to strike the fixed disks 37. The fixed disks 37 are impacted and generate vibrations, and then the vibrations are transmitted to the hopper 31, causing the fertilizer adhering to its inner wall to fall off, avoiding the situation of fertilizer residue.

[0031] Example 2, referring to Figures 1 - 12 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the spreading device 5 specifically includes a discharge pipe 51 provided at the bottom of the hopper 31, a ground-engaging plowshare 52 provided at the bottom end of the discharge pipe 51, a leakage outlet 53 opened on the outside of the ground-engaging plowshare 52; a rotating ring 54 provided inside the discharge pipe 51, a hanging rod 57 provided in the direction away from the hopper 31 of the rotating ring 54, a rotating groove 55 opened on the outside of the rotating ring 54, a positioning bolt 56 provided on the outside of the discharge pipe 51, and a driving motor 58 provided on the top of the traction frame 2.

[0032] Specifically, the discharge pipe 51 is fixed to the lower opening of the discharge port 32 by bolts. The discharge pipe 51 is inclined. The bottom end of the discharge pipe 51 is at the same height as the ground. The ground-touching plowshare 52 is welded to the discharge pipe 51. The ground-touching plowshare 52 gradually narrows toward the traction device 1 and is in a pointed shape. The leakage port 53 is located on the side of the ground-touching plowshare 52 away from the traction device 1. The rotating ring 54 is rotatably connected to the inner side of the discharge pipe 51. The rotating groove 55 is annular. The positioning bolt 56 penetrates the discharge pipe 51 and extends into the rotating groove 5 5, the hanging rod 57 is fitted with the inner wall of the discharge pipe 51, the side of the hanging rod 57 close to the discharge pipe 51 is triangular in design, and a tooth groove meshing with the drive motor 58 is provided on the outer side of the rotating ring 54; the hanging rods 57 are distributed in a circular array below the rotating ring 54; the inner wall of the discharge pipe 51 is fixedly connected with top blocks 59 distributed in a circular array, the top blocks 59 and the hanging rods 57 are staggered, the hanging rods 57 and the rotating ring 54 are rotatably connected, and a torsion spring is installed at the connection between the two, and the top block 59 is welded to the inner wall of the discharge pipe 51.

[0033] By setting up the storage device 3, the ground-touching plowshare 52 is buckled in the ditch dug by the ditching device 4. The soil in front can be pushed away during the movement, and the fertilizer falls along the discharge pipe 51 and the ground-touching plowshare 52 and leaks out from the leakage port 53. This can prevent the soil from blocking the fertilizer outlet. At the same time, a hanging rod 57 is set. When spreading fertilizer, the rotating ring 54 drives the hanging rod 57 to rotate in the discharge pipe 51. The hanging rod 57 constantly stirs the fertilizer inside the discharge pipe 51 and scrapes the inner wall of the discharge pipe 51. This can prevent the fertilizer from being blocked inside the discharge pipe 51 and ensure smooth fertilizer spreading.

[0034] By setting the top block 59, the hanging rod 57 will continuously contact the top block 59 during the rotation process, so that the hanging rod 57 will continuously deflect toward the central axis direction of the discharge pipe 51, so as to avoid the fertilizer from sticking between the hanging rods 57 and further improve the dredging effect.

[0035] An installation column 510 is provided at one end of the hanging rod 57 away from the hopper 31 , and a stirring bar 511 and a fixing cap 512 are provided on the outside of the installation column 510 ; the fixing cap 512 is threadedly connected to the installation column 510 , and the stirring bar 511 is made of flexible rubber, and the stirring bar 511 extends into the ground-touching plowshare 52 .

[0036] By providing the stirring bars 511 , the flexible stirring bars 511 extend into the irregular ground-contacting plowshares 52 , thereby preventing the fertilizer from being adhered to the ground-contacting plowshares 52 .

[0037] Based on Examples 1-2, the working principle of the farmland soil fertilizer based on the conversion of kitchen solid waste is as follows: During installation, slip cover 38 is sleeved outside fixed disk 37, then fixed disk 37 is attached to the inner wall of hopper 31, and then the return spring is fixed to one end of guide rod 311. Finally, guide rod 311 penetrates hopper 31 and fixed disk 37 from the outside of hopper 31, so that the other end of the return spring is fixed to slip cover 38. Rotating disk 36 is fixed to both ends of auxiliary screw 35, and then auxiliary screw 35 and pushing screw 33 are installed into hopper 31, and auxiliary screw 35 and pushing screw 33 are engaged with each other.

[0038] Stirring bar 511 is sleeved outside mounting post 510, and then fixing cap 512 is fixed to mounting post 510. Finally, hanging rod 57 is installed below rotating ring 54, and then hanging rod 57 and rotating ring 54 are inserted into discharge pipe 51. Then positioning bolt 56 is inserted into rotating slot 55 from the outside of discharge pipe 51, and finally discharge pipe 51 is fixed to the lower opening of discharge port 32.

[0039] During use, fertilizers are put into hopper 31, traction device 1 drives the device to move, and then ditching device 4, pushing motor 34 and driving motor 58 are started. During the movement of the device, ditching device 4 excavates a ditch on the ground. Pushing motor 34 drives pushing screw 33 to rotate, pushing screw 33 drives auxiliary screw 35 to rotate. Pushing screw 33 and auxiliary screw 35 rotate synchronously, continuously stirring the fertilizers in hopper 31, and pushing the fertilizers towards discharge port 32 through the threads. The fertilizers enter discharge pipe 51 through discharge port 32, and then the fertilizers are put into the ditch through ground-engaging plowshare 52. As the device moves, the fertilizers falling into the ditch leak out from leakage outlet 53.

[0040] After driving motor 58 is started, it drives rotating ring 54 to rotate. Rotating ring 54 drives hanging rod 57 to rotate while attaching to the inner wall of discharge pipe 51. During the rotation of hanging rod 57, it is continuously pushed towards the central axis direction of discharge pipe 51 by top block 59. After leaving top block 59, hanging rod 57 resets under the action of the torsion spring. In this way, hanging rod 57 stirs the fertilizers in discharge pipe 51 from multiple directions.

[0041] When the fertilizers in hopper 31 are about to be exhausted, slip cover 38 is pushed towards rotating disk 36 through guide rod 311, so that the pushing teeth 39 on the surfaces of slip cover 38 and rotating disk 36 are engaged with each other. Then, during the rotation of auxiliary screw 35, when the tips of the pushing teeth 39 on the surfaces of slip cover 38 and rotating disk 36 face each other, slip cover 38 is pushed towards fixed disk 37. Slip cover 38 impacts on the surface of fixed disk 37, causing fixed disk 37 to vibrate. Then hopper 31 follows the vibration, causing the fertilizers attached to the inner wall of hopper 31 to fall off.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
