[0002] Increasing the application of organic fertilizers can effectively improve soil structure, regulate pH, increase soil microbial communities, and increase soil organic matter content. It is an effective way to improve soil, improve soil fertility, and solve soil acidification and compaction problems.

[0003] For liquid fertilizer, it is usually sprayed by a sprayer, and for solid fertilizer, it is usually fertilized by a mobile carrier pulling a fertilizer spreader. In the prior art, the fertilizer spreader mainly includes a mobile carrier and a storage barrel mounted on the mobile carrier.

[0037] The utility model is further described below in conjunction with embodiments and drawings.

[0038] like Figure 1 and Figure 2 As shown, a mobile fertilizing device includes a vehicle body 1 and a storage box 2 mounted on the vehicle body 1, a discharge port 2a is formed at the bottom of the storage box 2, and the discharge port 2a is used to discharge organic fertilizer. A transmission mechanism 3 is installed on the vehicle body 1 at a position corresponding to the discharge port 2a, and a spreading device 4 is provided at the discharge end of the transmission mechanism 3. The spreading device 4 has a crushing function, and its lower part is exposed. After the organic fertilizer is transported to the spreading device 4 by the transmission mechanism 3, the organic fertilizer can be crushed by the spreading device 4 and sprinkled downward to the ground. A stirring mechanism 5 is also installed at the inner bottom of the storage box 2, and the stirring mechanism 5 is used to improve the fluidity of the fertilizer at the bottom of the storage box 2.

[0039] With such a design, when the vehicle body 1 moves with the storage box 2 on board, the organic fertilizer inside the storage box 2 can be discharged from the discharge port 2a to the transmission mechanism 3, and the transmission mechanism 3 transports the organic fertilizer to the spreading device 4 for further crushing, and finally spreads it more evenly from the bottom of the spreading device 4 to the soil surface, and the stirring mechanism 5 arranged at the bottom of the inner side of the storage box 2 can prevent the organic fertilizer from accumulating at the discharge port 2a and causing the discharge port 2a to be blocked.

[0040] Specifically, the bottom of the storage box 2 has two inclined bottom plates 2c, and the two bottom plates 2c are arranged in a "V" shape. The discharge port 2a is formed between the lower ends of the two bottom plates 2c, so as to ensure that the organic fertilizer is more easily discharged from the discharge port 2a, and the stirring mechanism 5 is symmetrically arranged on both sides of the discharge port 2a. In the present embodiment, the stirring mechanism 5 includes a rotating rod 5a rotatably mounted on the upper surface of the bottom plate 2c, and a first motor 5b driving the rotating rod 5a to rotate, and the first motor 5b is fixedly arranged on the lower side of the bottom plate 2c. The left and right sides of the discharge port 2a are both formed with two stirring mechanisms 5. Under the rotation of the four stirring mechanisms 5, the organic fertilizer inside the storage box 2 can be effectively prevented from caking, and it can also be beneficial for the organic fertilizer to be discharged from the discharge port 2a, preventing the organic fertilizer from blocking the discharge port 2a. A feed port 2b is also provided at the top of the storage box 2, and the feed port 2b can facilitate the storage box 2 to be filled with organic fertilizer.

[0041] like Figure 2 and Figure 5As shown, an electric opening and closing mechanism 6 is also arranged on the discharge port 2a, and the electric opening and closing mechanism 6 includes two baffle plates 6b rotatably mounted on the discharge port 2a, and two groups of first driving components 6a respectively driving the two baffle plates 6b to rotate. By driving the baffle plates 6b to rotate back and forth by the first driving components 6a, the discharge port 2a can be continuously opened and closed, thereby playing a role in controlling the discharge amount and discharge speed of organic fertilizer.

[0042] In this embodiment, the transmission mechanism 3 is a rotary belt feeding mechanism, which specifically includes two rotating rods 3a arranged in parallel and rotating synchronously and a synchronous crawler 3b connecting the two rotating rods 3a. Figure 3 As shown, one end of one of the rotating rods 3 a is connected to a second motor 19 , a synchronous belt 20 is connected between the output end of the second motor 19 and the rotating rod 3 a , and synchronous transmission is performed through the synchronous belt 20 .

[0043] In this embodiment, the transmission mechanism 3 is arranged at an angle, and one end of the transmission mechanism 3 close to the spreading device 4 is higher than the other end, so as to ensure that the organic fertilizer can be transported to the spreading device 4 at a steady and slow speed, which can effectively avoid clogging of the spreading device 4 due to too fast transportation.

[0044] A conveyor belt shell 7 is provided in the circumferential direction of the transmission mechanism 3, and the storage box 2 is against the top of the conveyor belt shell 7, so that the conveyor belt shell 7 and the storage box 2 form a whole, which ensures the stability of the overall structure and the aesthetics of the overall structure. The conveyor belt shell 7 is also provided with an inspection port 7a, which can facilitate the maintenance personnel to inspect and maintain the transmission mechanism 3 and the first motor 5b, so as to ensure the normal use of the fertilization device.

[0045] In this embodiment, a mounting base 9 is provided at the bottom of the conveyor belt housing 7, and the mounting base 9 is fixedly mounted on the vehicle body 1, so as to ensure that the vehicle body 1 can stably carry the transmission mechanism 3 and the storage box 2.

[0046] like Figure 4As shown, the spreading device 4 includes a mounting base 4c fixedly mounted relative to the vehicle body 1. In this embodiment, the mounting base 4c is fixedly connected to the rear end of the mounting base 9. Two rollers 4a arranged in parallel are rotatably mounted on the mounting base 4c. The rotation directions of the two rollers 4a are opposite. The mounting base 4c is provided with a second driving assembly 4d for driving the rollers 4a to rotate. The surface of the rollers 4a is provided with spiral blades 4b. The transmission mechanism 3 can transport the organic fertilizer to the middle position of the top of the two rollers 4a. The organic fertilizer can be further crushed by the rolling action of the two rollers 4a and the spiral blades 4b and can be thrown from the bottom of the rollers 4a to the soil surface. A protective shell 8 is provided on the circumference and top surface of the spreading device 4. The protective shell 8 can effectively prevent people from directly contacting the rollers 4a, reducing safety hazards, and can also be connected with the conveyor belt shell 7, making the overall appearance more beautiful. An observation port 8a is provided on one side of the protective shell 8 away from the conveyor belt shell 7. The observation port 8a can facilitate real-time observation of the use status of the roller 4a, thereby ensuring normal spreading of the organic fertilizer.

[0047] Since solid organic fertilizer is only thrown on the soil surface, it cannot effectively fertilize the soil in depth, and the effect will be greatly reduced under the sun. Therefore, according to the texture and hardness of the soil, the plowing component A and the rotary tillage component B can be freely installed at the rear end of the vehicle body 1. Figure 1 As shown, in this embodiment, a plowing assembly A is installed at the rear end of the vehicle body 1, and a rotary tillage assembly B is installed at the rear end of the plowing assembly A. The plowing assembly A can turn over the deep soil, and the rotary tillage assembly B can crush and mix the turned-over soil blocks with organic fertilizer, thereby ensuring the fertility effect of the solid organic fertilizer.

[0048] Specifically, Figure 6 As shown, the plowing assembly A includes a mounting frame 10 and a plow blade 11 arranged at the bottom of the mounting frame 10, one end of the mounting frame 10 is hinged at the rear end of the mounting base 4c, and a first hydraulic cylinder 12 is also installed between the mounting base 4c and the mounting frame 10, and the two ends of the first hydraulic cylinder 12 are respectively hinged at the middle position of the rear end of the mounting base 4c and the front end of the mounting frame 10. The first hydraulic cylinder 12 can control the rotation of the mounting frame 10 relative to the vehicle body 1 by telescopic movement, so that the plow blade 11 can be inserted into the soil.

[0049] With such a design, the plowing assembly A is controlled to move downward by the first hydraulic cylinder 12, and the plow blade 11 is inserted into the soil. Then the vehicle body 1 moves forward, dragging the plow blade 11 in the soil layer, so that the deep soil can be turned up, thereby achieving the purpose of merging the fertilizer with the soil, and effectively avoiding the loss and volatilization of the fertilizer.

[0050] In this embodiment, the mounting frame 10 and the first hydraulic cylinder 12 are specifically hinged at the rear end of the mounting base 9. Figure 6As shown, a third hydraulic cylinder 21 is also installed between the mounting base 9 and the mounting frame 10, the first hydraulic cylinder 12 and the third hydraulic cylinder 21 are distributed up and down, and both ends of the third hydraulic cylinder 21 are hinged at the middle position of the rear end of the mounting base 9 and the middle position of the lower end of the mounting frame 10. In this embodiment, the first hydraulic cylinder 12 is used to place the plow 11 on the ground surface, and the third hydraulic cylinder 21 is used to insert the plow 11 into the ground.

[0051] like Figure 7 As shown, the mounting frame 10 is a rectangular frame, and an array of plowshares 11 is distributed below two edges at the bottom of the mounting frame 10, and the two rows of plowshares 11 are cross-distributed with each other. In this embodiment, a total of thirteen plowshares 11 are installed, seven plowshares 11 are arranged on the edges close to the vehicle body 1, and six plowshares 11 are arranged on the edges away from the vehicle body 1. The bottom of each plowshare 11 is bent toward the vehicle body 1. Such a design makes it easier to turn over deep soil so that the soil can be mixed with organic fertilizer.

[0052] like Figure 6 As shown, when actually ploughing, if the soil surface height is inconsistent, the plowing depth will be inconsistent. Based on this, in this embodiment, positioning wheels 13 are installed on the left and right sides of the mounting frame 10. The positioning wheels 13 are mainly used for driving on the ground. The positioning wheels 13 are also provided with detection elements, which are used to detect the rotation resistance of the positioning wheels 13 in real time. The detection element is associated with the third hydraulic cylinder 21 through the control module, and the detected data can be fed back to the third hydraulic cylinder 21 in real time. The third hydraulic cylinder 21 can adjust the insertion depth of the plow blade 11 in real time according to the detection data, so that the depth of the groove plowed by the plowing assembly A is consistent.

[0053] Further, such as Figure 8 As shown, a beam structure 10a is welded on the top of the mounting frame 10, and one end of the first hydraulic cylinder 12 is hinged at the middle position of the top of the beam structure 10a. With this design, the structure of the entire mounting frame 10 is more stable through the beam structure 10a, and the distance between the two hinge points of the first hydraulic cylinder 12 and the third hydraulic cylinder 21 on the mounting frame 10 is also increased. Compared with directly hingedly connecting the first hydraulic cylinder 12 to the mounting frame 10, at this time, the first hydraulic cylinder 12 only needs a shorter driving stroke to achieve a large-scale up and down movement of the plowing component A, thereby reducing the overall kinetic energy consumption.

[0054] A triangular frame 10b is also extended toward the vehicle body 1 on the left and right sides of the beam-like structure 10a. In the present embodiment, the triangular frame 10b is an isosceles right triangle structure, and one of the acute angles is hinged at the rear end of the mounting base 4c. The first hydraulic cylinder 12 and the third hydraulic cylinder 21 are arranged between the two triangular frames 10b. Such a design further ensures that the connection between the vehicle body 1 and the plowing assembly A is more stable.

[0055] like Fig. 9 As shown, in this embodiment, an outer shell 22 is installed on the surface of the mounting frame 10 and the beam structure 10a. The outer shell 22 can not only protect the plowing assembly A, but also ensure the overall aesthetics of the plowing assembly A.

[0056] For example Fig.10 and Fig.12 As shown, the rotary tillage assembly B includes a rotary tillage bracket 14 extending along the width direction of the vehicle body 1 and a rotating shaft 15 rotatably mounted at the lower part of the rotary tillage bracket 14. A rotary tillage blade group 16 is mounted on the rotating shaft 15 along its axial array. A third driving assembly 17 is also mounted on the outer side of the rotary tillage bracket 14. The third driving assembly 17 is used to drive the rotating shaft 15 to rotate, thereby allowing the rotary tillage blade group 16 to rotate. In this embodiment, the front end of the rotary tillage bracket 14 is hinged at the rear end bottom of the mounting frame 10. A second hydraulic cylinder 18 is also connected between the mounting frame 10 and the rotary tillage bracket 14. The two ends of the second hydraulic cylinder 18 are respectively hinged at the middle position of the top end of the beam structure 10a and the middle position of the front end of the rotary tillage bracket 14. When the second hydraulic cylinder 18 performs telescopic movement, it can control the rotary tillage bracket 14 to rotate relative to the plowing assembly A, so that the rotary tillage blade group 16 can be inserted downward into the soil. With such a design, the second hydraulic cylinder 18 is used to control the rotary tillage component B to move downward, causing the rotary tillage blade group 16 to be inserted into the soil, the third drive component 17 is started, and the vehicle body 1 pulls the rotary tillage component B to move, so that the soil blocks turned over by the plowing component A and the organic fertilizer can be crushed and mixed together, thereby making the organic fertilizer mixed more evenly.

[0057] like Fig.11 As shown, the rotary tillage support 14 includes a horizontally arranged main mounting plate 14a and side mounting plates 14b formed below the left and right sides of the main mounting plate 14a. The rotating shaft 15 is rotatably arranged between the two side mounting plates 14b, and the third driving assembly 17 is fixedly mounted on the outer side of one of the side mounting plates 14b.

[0058] like Fig.10 As shown, a mounting bracket 23 is provided at the middle position of the front end of the main mounting plate 14a, and the cylinder rod of the hydraulic cylinder 6 is hinged on the mounting bracket 23, and the cylinder barrel of the second hydraulic cylinder 18 is hinged at the middle position of the top of the beam-like structure 10a. Connecting rods 24 are also hinged at the left and right ends of the mounting bracket 23, and the distal ends of the two connecting rods 24 are hinged at the rear end bottom of the mounting frame 10. In actual use, the side of the second hydraulic cylinder 18 close to the plowing component A is affected by the deadweight of the rotary tillage component B, and usually rests on the beam-like structure 10a. In this way, the connection between the plowing component A and the rotary tillage component B is more stable, and it is ensured that when the second hydraulic cylinder 18 is extended or retracted, it can drive the rotary tillage component B to rotate, thereby playing the function of adjusting the rotary tillage depth.

[0059] like Fig.12 and Fig.13 As shown, the rotary tiller blade group 16 includes two rotary tillers 16a both extending radially outward along the rotating shaft 15. The rotary tillers 16a of any two adjacent rotary tiller blade groups 16 are arranged in a staggered manner. The rotary tiller blade 16a has a curved section 16a1 located in a vertical plane. One end of the curved section 16a1 is fixedly connected to the rotating shaft 15, and the other end has a side curved section 16a2 that is curved to the side. With such a design, the curved section 16a1 is provided to facilitate the installation of the rotary tiller blade 16a, and the side curved section 16a2 is more conducive to breaking up soil blocks and fully mixing with organic fertilizer. The staggered arrangement of the rotary tiller blades 16a reduces the area of ​​the rotary tiller blade group 16 contacting the soil at the same time, thereby reducing the driving resistance when the vehicle body 1 pulls the rotary tiller assembly B to move.

[0060] like Fig.11 As shown, a mudguard 14c is rotatably mounted on the rear end of the main mounting plate 14a, and a guide portion 14c1 inclined backward is formed at the bottom of the mudguard 14c. The mudguard 14c can effectively prevent the soil or organic fertilizer from splashing everywhere when the rotary tillage blade group 16 breaks the mixed soil and organic fertilizer; after the rotary tillage blade group 16 breaks the mixed soil and organic fertilizer, the guide portion 14c1 allows the land surface to remain flat.

[0061] Further, such as Fig.11 and Fig.14 As shown, a support rod 25 is hinged on the outer side of the bottom of the mud guard 14c, and a positioning hole 25a is arranged in an array at one end of the support rod 25 away from the hinge point. A positioning seat 14d is extended backward from the rear end of the main mounting plate 14a, and a pin is inserted between the positioning hole 25a and the positioning seat 14d so that the rotation angle of the mud guard 14c can be fixed. In this embodiment, two support rods 25 are hinged on the outer side of the bottom of the mud guard 14c, and the mud guard 14c can be fixed more stably through the two support rods 25. Such a design can ensure that the mud guard 14c can adjust the angle adaptively when the rotary tillage component B is rotary tilled at different depths by inserting the pin into different positioning holes 25a. While not affecting the normal operation of the rotary tillage component B, it can also prevent soil or organic fertilizer from splashing everywhere, and keep the surface of the land after rotary tillage flat.

[0062] In this embodiment, two sets of rubber tracks 1a are symmetrically installed at the bottom of the vehicle body 1. The rubber tracks 1a are particularly suitable for traveling on the land and can provide greater traction and driving force, so that the plowing component A and the rotary tillage component B can move more stably, thereby ensuring sufficient mixing of the soil and organic fertilizer.

[0063] Combined with the above structure, the specific working process of the mobile fertilization device described in the utility model is as follows:

[0064] Before fertilizing, the first hydraulic cylinder 12 controls the plowing assembly A to rotate downward so that the plow blade 11 is placed on the soil surface, and then the plow blade 11 is controlled to be inserted into the soil through the third hydraulic cylinder 21, and the positioning wheel 13 is close to the soil surface. The second hydraulic cylinder 18 controls the rotary tillage assembly B to rotate downward so that the rotary tillage blade 16a is inserted into the soil, and the support rod 25 is adjusted to rotate the fender 14c to a suitable position so that the guide part 14c1 is slightly higher than the soil surface. When fertilizing begins, the vehicle body 1 starts to move in the soil. At the same time, the transmission mechanism 3, the spreading device 4, the stirring mechanism 5 and the third driving assembly 17 start to start. The electric opening and closing mechanism 6 also starts regular opening and closing movements, and the organic fertilizer falls onto the transmission mechanism 3 through the discharge port 2a, and is transported by the transmission mechanism 3 to the spreading device 4 for fine crushing, and is finally sprinkled from the bottom of the spreading device 4 to the soil surface, and then the plow 11 is pulled by the vehicle body 1 to turn over the soil so that the deep soil and the solid organic fertilizer are preliminarily mixed, and the soil blocks and the solid organic fertilizer after the preliminary mixing are further crushed and mixed by the rotary tillage component B, so that the soil and the organic fertilizer are more fully mixed, and the mixed soil is acted on by the guide part 14c1, so that the land surface is restored to be flat.

[0065] Combination Fig.15 When the vehicle body 1 pulls the plowing component A to move, the positioning wheel 13 can also move with it. Under normal conditions, the positioning wheel 13 is as shown in a in the figure. When the positioning wheel 13 moves to the position at b in the figure, the driving resistance detected by the detection element on the positioning wheel 13 is constantly decreasing. When the driving resistance is less than the set driving resistance range, the detection element will feed back the detection result to the third hydraulic cylinder 21, and the third hydraulic cylinder 21 can drive the plowing component A to move downward, so that the driving resistance of the positioning wheel 13 returns to the set range; when the positioning wheel 13 moves to the position at c in the figure, the driving resistance detected by the detection element is constantly increasing. When the driving resistance is greater than the set driving resistance range, the detection element will feed back the detection result to the third hydraulic cylinder 21, and the third hydraulic cylinder 21 can drive the plowing component A to move upward until the driving resistance of the positioning wheel 13 drops to the set driving resistance range.

[0066] Through the real-time dynamic adjustment of the third hydraulic cylinder 21, the depth of the grooves plowed by the plowing component A is guaranteed to be consistent, and there will be no problem of inconsistent plowing depth due to different soil surface heights. While the plowing component A is dynamically adjusted up and down, it can also drive the rotary tillage component B to be dynamically adjusted, thereby ensuring that the soil and organic fertilizer can be evenly mixed.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
