[0002] When the soil cannot provide the nutrients required for crop growth and development, artificially supplementing the crops with nutrients is called fertilization. Therefore, fertilizing crops is inevitable. However, existing soil fertilization devices have some shortcomings during use. Existing soil fertilization devices generally apply fertilizer to the soil surface or at a shallow depth, resulting in severe fertilizer loss and low fertilization quality.

[0003] In addition, existing fertilization practices often use a large amount of chemical fertilizers. However, long-term application of chemical fertilizers can lead to a decline in soil quality, which is not conducive to the green and high-quality development of agriculture. my country has abundant organic materials such as straw and livestock manure, which are widely available. The rational application of organic fertilizers is of great significance to the development of agriculture and the efficient use of resources in my country.

[0004] However, the current method of applying organic fertilizers is to spread the fertilizer on the land surface and then mix it with the soil through methods such as rotary tillage. Existing methods of applying organic fertilizers often have the following defects: 1. The traditional method of applying organic fertilizers causes great disturbance to the soil during rotary tillage and mixing, which can easily destroy the structure of soil aggregates and is not conducive to carbon sequestration and emission reduction; 2. The traditional method of applying organic fertilizers is inefficient and energy-intensive, and cannot complete the application of organic fertilizers in one go; 3. The traditional method of applying organic fertilizers has a shallow tillage depth, and organic fertilizers are mostly concentrated in the topsoil layer, resulting in poor application effect and failure to achieve the goal of high-efficiency agricultural production; 4. The amount of organic fertilizer applied by the traditional method of applying organic fertilizers cannot be accurately controlled, resulting in uneven application; 5. The material is not discharged smoothly during the fertilization process, and is prone to blockage. Summary of the Invention

[0029] (1) The present invention relates to an organic fertilizer fertilizing device. A feed assembly is provided within an auxiliary material box. The feed assembly includes a rotatable screw with spiral blades disposed on the outside of the screw. The lower end of the screw with the spiral blades extends into a fertilizer pipe.

For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0047] This embodiment provides an organic fertilizer application device for use in the application of organic fertilizers. Organic fertilizers primarily refer to farmyard manure, and any fertilizer made from organic matter (compounds containing carbon) is considered organic fertilizer. This embodiment primarily describes organic manure, which is applied using this application device.

[0048] like Figure 1As shown, an organic fertilizer fertilizing device includes a main material box 1, an auxiliary material box 2 and a feeding assembly 4. It also includes a bracket 7, and the main material box 1 and the auxiliary material box 2 are fixedly arranged relative to the bracket 7, and the main material box 1 is fixedly mounted on the bracket 7. The auxiliary material box 2 can also be fixedly connected to the bracket 7, or it can be fixedly connected to the main material box 1. The bracket 7 is also used to connect with a tractor to drive the fertilizing device to move. The tractor can be a tractor or other device. Relative to the forward direction of the fertilizing device, rotating ground wheels (not shown in the figure) are respectively installed on the left and right sides of the bracket 7. When the tractor moves forward, it drives the rotating ground wheels to rotate, thereby driving the fertilizing device forward.

[0049] Specifically, the main material box 1 is used to contain organic fertilizers, and at least one outlet is provided below the main material box. Figure 1 In this embodiment, five branch outlets are provided below the main material box 1, and the branch outlets are arranged at intervals. The organic fertilizer in the main material box 1 flows out through the branch outlets.

[0050] The auxiliary material box 2 has at least one outlet, corresponding to the outlet of the main material box 1. The number of auxiliary material boxes 2 corresponds to the number of outlets of the main material box 1. For example, in this embodiment, if the main material box 1 has five outlets, the number of auxiliary material boxes 2 should also be five. The inlet of each auxiliary material box 2 is connected to a outlet of the main material box 1, and the organic fertilizer flowing out of the outlet of the main material box 1 enters the auxiliary material box 2.

[0051] Each auxiliary material box 2 is provided with a blanking assembly 4. The blanking assembly 4 includes a rotatable screw 42, and a spiral blade 43 is provided on the outer side of the screw 42; the lower end of the screw 42 is connected to a fertilizer pipe 44, and the other end of the fertilizer pipe 44 is connected to a furrow opener 5.

[0052] Specifically, an outlet is provided below the auxiliary material tank 2, and the side of the outlet of the auxiliary material tank 2 is tilted so that organic fertilizer can be collected at the outlet. One end of a fertilizer pipe 44 is connected to the outlet of the auxiliary material tank 2. The lower end of a screw 42 with a spiral blade 43 extends into the fertilizer pipe 44. The other end of the fertilizer pipe 44 is connected to a furrow opener 5. During the forward movement of the fertilization device, the furrow opener 5 extends into the field, and the organic fertilizer in the main material tank 1 enters the auxiliary material tank 2 through the branch outlet. The spiral blade 43 rotates with the screw 42 to transport the organic fertilizer into the fertilizer pipe 44, and finally discharged through the fertilizer pipe 44 and applied to the soil.

[0053] A soil covering component 3 is further provided at the rear side of the fertilizing device, and the soil covering component 3 covers the fertilizing area with soil when rotating.

[0054] The upper end of screw 42 is connected to a driver 41, which is used to drive screw 42 in rotation. In one embodiment, driver 41 is a motor. To prevent interference between spiral blade 43 and fertilizer pipe 44 during rotation, a certain gap is provided between the outer side of spiral blade 43 and the inner side of fertilizer pipe 44. This gap also prevents fertilizer clogging.

[0055] In this embodiment, the shaft diameter of the screw 42 is d, the outer diameter of the spiral blade 43 is D, and the pitch of the spiral blade 43 is s, where d=20%D~30%D, and s=0.8D~1.0D.

[0056] Combine Figure 2 and Figure 3 As shown, in this solution, a feeding assembly 4 is installed within the auxiliary material box 2. The feeding assembly 4 includes a rotatable screw 42 with a spiral blade 43 disposed on the outside of the screw 42. The lower end of the screw 42 with the spiral blade 43 extends into a fertilizer pipe 44. The organic fertilizer in the auxiliary material box 2 is guided and transported by the rotating spiral blade 43 and discharged through the fertilizer pipe 44, thus avoiding fertilizer blockage. In addition, d = 20%D to 30%D, s = 0.8D to 1.0D. Compared with inorganic fertilizer, organic fertilizer has larger particles and higher viscosity, which can increase the amount of organic fertilizer discharged and further avoid blockage.

[0057] The fertilizing device in this scheme is mainly used for fertilizing organic fertilizers, wherein the organic fertilizers are organic manure. Specifically, the bulk density of the organic fertilizers is In 600-800 Bulk density is also called volume density. Bulk density of organic fertilizer refers to the mass per unit volume measured after the organic fertilizer is freely filled in a container.

[0058] As a further improvement, the outer diameter D of the spiral blade 43 is 0.08-0.12 m. In a specific embodiment, the outer diameter D of the spiral blade 43 can be 0.08 m, 0.085 m, 0.09 m, 0.095 m, 0.10 m, 0.105 m, 0.11 m, 0.115 m, or 0.12 m.

[0059] Furthermore, the thickness of the spiral blade 43 is 4 to 6 mm. In a specific embodiment, the thickness of the spiral blade 43 can be 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, 5 mm, 5.1 mm, 5.2 mm, 5.3 mm, 5.4 mm, 5.5 mm, 5.6 mm, 5.7 mm, 5.8 mm, 5.9 mm, or 6 mm.

[0060] A certain gap is set between the outer side of the spiral blade 43 and the inner side of the fertilizer pipe 44, and the gap is 2-3 cm.

[0061] In this embodiment, the organic fertilizer is transported by the spiral blades 43 in the auxiliary material box 2 before being discharged through the fertilizer pipe 44. Compared with inorganic fertilizers, organic fertilizer particles are larger and have a higher moisture content. Setting d to 20%D to 30%D ensures the strength of the screw 42 while avoiding reducing the fertilizer delivery rate. Similarly, setting s to 0.8D to 1.0D avoids a spiral blade 43 with a pitch that is too small, which would affect the delivery of organic fertilizer particles, and a spiral blade 43 with a pitch that is too large, which would reduce the fertilization effect and lead to uneven fertilization.

[0062] Combine Figure 4 and Figure 5 As shown, as a preferred embodiment, the height of the furrow opener 5 is greater than 20 cm. Applying fertilizer to a depth of at least 20 cm from the soil can reduce ammonia loss. Experimental results show that ammonia volatilization losses can reach 30% when applied to the surface of the soil, while this loss can be reduced to less than 10% when applied 20 cm deeper. Deep application of fertilizer to the soil can also promote root growth of crops.

[0063] Preferably, the entry angle α of the furrow opener 5 is between 18° and 22°. Specifically, the entry angle is the angle between the upper inclined side 51 of the furrow opener 5 and the plane of the field. Setting the entry angle reduces the traction resistance of the fertilizer application device and improves the soil-breaking ability of the furrow opener 5.

[0064] In some cases, different soil conditions or different functions require different fertilization depths. In order to improve the versatility of the fertilizing device, an adjustment component 6 is set on the outside of the fertilizing pipe 44. The fertilizing pipe 44 is also connected to the furrow opener 5. The adjustment component 6 is mainly used to adjust the height of the furrow opener 5 and the fertilizing pipe 44, so as to adjust the fertilization depth of the fertilizing device according to actual needs. Specifically, the adjustment component 6 includes a second support 62 connected to the fertilizing pipe 44, a first support 61 fixedly arranged relative to the bracket 7, and an adjustment rod 63 connecting the second support 62 and the first support 61. The second support 62 is movably connected to the first support 61. In a specific embodiment, see Figure 5 In the figure, one end of the adjusting rod 63 is fixedly connected to the second support 62, and the other end is slidably connected to the first support 61. When adjustment is required, the second support 62 is moved to the required position. The end of the second support 62 close to the first support 61 can be fixed in the limiting hole 611 by bolts or screws, and the limiting hole 611 is opened on the first support 61.

[0065] In this solution, the organic fertilizer particles contained in the main material box 1 are relatively large. When being transported by the spiral blade 43, they are sometimes prone to getting stuck, for example, getting stuck in the gap between the spiral blade 43 and the fertilizer pipe 44, causing the fertilization process to stagnate. In order to avoid this situation, the fertilization device also includes a crushing component, which is specifically located at the outlet of the main material box 1. Figure 2 and Figure 3 As shown, a crushing assembly is provided at each branch outlet. The crushing assembly includes a first meshing shaft 11 and a second meshing shaft 12 that mesh with each other, and the outer sides of the first meshing shaft 11 and the second meshing shaft 12 are each provided with meshing teeth. A drive motor can be connected to the first meshing shaft 11 and the second meshing shaft 12 to drive the first meshing shaft 11 and the second meshing shaft 12 to rotate. There are multiple first meshing shafts 11, and adjacent first meshing shafts 11 can be connected by a coupling; similarly, there are multiple second meshing shafts 12, and adjacent second meshing shafts 12 can be connected by a coupling. The coupling is located in the interval between the branch outlets of the main material box 1 and does not occupy the space of the branch outlet. The organic fertilizer in the main material box 1 flows through the branch outlet to between the first meshing shaft 11 and the second meshing shaft 12. The rotating first meshing shaft 11 and the second meshing shaft 12 crush the organic fertilizer. The crushed organic fertilizer enters the auxiliary material box 2 and is finally transported to the fertilizer pipe 44 for fertilization via the spiral blade 43. The crushed organic fertilizer can be transported more smoothly through the spiral blades 43, and the fertilization is more uniform, and the amount of fertilizer is easier to control.

[0066] The fertilizing device in this solution can apply fertilizer to a depth of less than 20 cm, minimizing soil disturbance. The furrow opener 5 is optimized to reduce the traction power consumption of the fertilizing device. The spiral blades 43 and screw 42 are optimized to reduce the problem of clogging during organic fertilizer application. Furthermore, the crushing assembly crushes the fertilizer before application, further preventing organic fertilizer blockage while also ensuring more uniform fertilization and facilitating control of the fertilizer application rate.

[0067] The present application also provides a control system for the organic fertilizer fertilizing device, including a humidity sensor 21, a speed sensor and a control terminal. The humidity sensor 21 is installed on the auxiliary material box 2 and is used to monitor the humidity of the organic fertilizer; the speed sensor includes a traction speed sensor and a screw speed sensor. The traction speed sensor is used to monitor the speed v of the fertilizing device being pulled, and the screw speed sensor is used to monitor the speed n of the screw 42; the humidity sensor 21 and the speed sensor are both connected to the control terminal.

[0068] Different fields and different crops have quantitative requirements for fertilization.

[0069] The present application also provides a control method for an organic fertilizer fertilizing device, including the organic fertilizer fertilizing device, for controlling the speed at which the fertilizing device is towed and the rotational speed of the screw 42. Specifically, when the organic fertilizer fertilizing device is towed and moved, the screw 42 rotates, and the organic fertilizer in the main material box 1 is transported into the fertilizer pipe 44 through the screw 42 for fertilization.

[0070] During the fertilization process, the amount of fertilizer applied per unit area is related to the speed v of the fertilizing device and the rotation speed n of the spiral blade 43 and the screw 42, which is difficult to adjust manually. In this solution, the relationship between the speed v and the rotation speed n is adjusted through the control terminal.

[0071] Specifically, the humidity of organic fertilizer is , when 10%< When the ratio is ≤40%, the control terminal corrects the speed v of the fertilizer application device being pulled and the speed n of the screw 42, and the correction is performed in the following manner:

[0072] ;

[0073] in ;

[0074] G is the target fertilizer amount per unit area (kg / mu), is the fill factor. is a constant, ranging from 0.25 to 0.5, and is related to the bulk density of organic fertilizers. When the bulk density is large, a high value is taken, such as 0.4 or 0.5. When the bulk density is large, a low value is taken, such as 0.3 or 0.25.

[0075] From the above, we can see that when 、Screw structure parameters( ) is fixed, the screw speed n is linearly proportional to the traction speed v. At the same time, according to the moisture content of the organic fertilizer, the screw speed n and the traction speed v are adjusted to automatically control the screw speed n and the traction speed v, so as to more accurately realize the fertilizer application amount G per unit area and ensure the uniformity and accuracy of fertilization.

[0076] In addition, when When the humidity is less than 10%, the humidity sensor does not need to be involved. .

[0077] when When the humidity is higher than 40%, the organic fertilizer has a high moisture content and the screw is difficult to control the amount of fertilizer. At this time, it is necessary to stop the machine for inspection or slow down the screw. When the screw slows down, the screw speed Reduced to , to avoid the screw speed n being too high, which may cause the organic fertilizer to be thrown out and separated from the spiral blade 43 due to centrifugation, making it difficult for the spiral blade 43 to transport it.

[0078] This solution addresses the problem of clogging during mechanized use of organic fertilizers by rationally designing the feed assembly structure. A control system is also implemented to control the traction speed of the fertilizer application device and the rotational speed of the feed assembly, making the equipment intelligent, mechanized, precise, and efficient.

[0079] When the humidity of organic fertilizer 10%< When the humidity is ≤40%, the humidity compensation corrects the pulling speed of the fertilizer device and the rotation speed of the feeding component to more accurately control the fertilizer amount G.

[0080] Using graded control, the fertilizing device's pulling speed and the rotational speed of the feeding assembly are adjusted differently to accommodate the varying moisture levels of the organic fertilizer, thereby precisely controlling the fertilizer application rate G based on the fertilizer's state. Furthermore, the device is adaptable to varying operating environments. For example, if it rains during fertilization, the moisture level of the organic fertilizer changes. The humidity control model allows for adaptability to these changes, ensuring smooth operation.
