Description

Technical Field

[0001] This application relates to the field of agricultural soil tillage machinery and equipment, specifically to a high-efficiency soil loosening and fertilization compound machinery. Background Technology

[0002] In modern agricultural production, soil tillage, namely loosening the soil and fertilization, are two crucial operational steps. Traditional methods typically involve separate steps: first, rotary tillers or subsoilers are used to break up and loosen the soil, followed by manual or machine-applied fertilizer spreading or furrow application. This approach is inefficient, and the separate steps result in uneven fertilization depth. Fertilizer exposed on the surface also leads to volatilization losses, especially nitrogen fertilizer. Furthermore, insufficient contact between fertilizer and crop roots reduces fertilizer utilization. To overcome these drawbacks and achieve the requirements of "precision agriculture" and "conservation tillage," integrated machinery combining soil loosening and fertilization functions has become a development trend. This type of machinery is mainly used for basal fertilizer application in field crops (such as corn and wheat), topdressing in orchards or greenhouses, and ridge fertilization in nurseries. The core objective is to complete soil loosening, deep fertilizer application, and soil covering in a single operation, thereby reducing the number of times the machinery compacts the soil, improving operational efficiency, and promoting nutrient absorption by crops.

[0003] Currently, existing soil loosening and fertilization compound machinery still has problems. During the fertilization process, the operation quality is unstable and the uniformity is poor. Highly hygroscopic fertilizers are prone to arching or bridging in the fertilizer tank, resulting in uneven fertilizer application. In addition, the discharge volume of traditional mechanical fertilizer dispensers is significantly affected by the fluctuation of tractor speed, making it impossible to achieve constant fertilizer application. The fertilization depth is also inconsistent, affecting the uniformity of seedling emergence.

[0004] Therefore, it is necessary to provide a high-efficiency soil loosening and fertilization compound machinery to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, this application provides the following technical solution: a high-efficiency soil loosening and fertilization compound machinery, including a trailer, a deep loosening component, a fertilizer supply component, an auxiliary adjustment component, and a hot air blower. The deep loosening component is mounted on the rear end of the trailer. The deep loosening component, the auxiliary adjustment component, and the fertilizer supply component are stacked sequentially. The fertilizer supply component includes a feeding bin with a bottom feeding port at the bottom and a side feeding port on the side wall facing the trailer. A hot air interface is provided on the side wall of the feeding bin near the bottom feeding port. The auxiliary adjustment component includes a fixed frame fixed to the upper end of the deep loosening component. A front auxiliary material bin and a rear auxiliary material bin are sequentially arranged on the upper end of the fixed frame away from the trailer. Multiple feeder groups are arranged at the lower ends of the front and rear auxiliary bins. The upper input port of the front auxiliary material bin is connected to the side feeding port through a front conveying pipe. The upper input port of the rear auxiliary bin is connected to the bottom feeding port. A hot air blower is also provided on the fixed frame, and the output end of the hot air blower is connected to the hot air interface.

[0006] Furthermore, as a preferred embodiment, both the pre-feeding and post-feeding material silos are equipped with temporary storage space. The pre-feeding material conveying pipe is made of flexible material. The upper input port of the post-feeding material silo is loosely connected to the lower feeding port. Control switches are installed between the pre-feeding material silo and the pre-feeding material conveying pipe, as well as between the upper and lower feeding ports of the post-feeding material silo. The control switches are equipped with particle size monitors.

[0007] Furthermore, as a preferred embodiment, the subsoil assembly includes a support frame connected to a trailer via an auxiliary connecting frame, and multiple subsoil shovels are fixedly mounted on the lower end of the support frame via fasteners.

[0008] Furthermore, as a preferred option, the subsoil shovel assembly is arranged in two rows, corresponding to the front auxiliary material bin and the rear auxiliary material bin.

[0009] Furthermore, as a preferred embodiment, the deep loosening shovel assembly includes a connecting seat connected to a fixing member, with an arm extending from the lower end of the connecting seat. A soil-dividing shovel is fixedly and inclined at the lower end of the arm, and a groove is opened at the lower end of the arm. A soil-breaking component is installed in the groove, and multiple through holes are evenly distributed near the rear end of the soil-breaking component. The soil-breaking component and the arm are temporarily fixed by bolts and through holes.

[0010] Furthermore, as a preferred embodiment, the fertilizer supply assembly also includes a movable material leakage trough that is slidably disposed on the inner wall of the feeding hopper. The sliding area of ​​the movable material leakage trough corresponds to the feeding port on the side wall, and a baffle that fits against the inner wall of the feeding hopper is fixedly disposed around the movable material leakage trough.

[0011] Furthermore, as a preferred embodiment, the fertilizer supply assembly also includes an auxiliary connecting rod, one end of which is hinged to the outer wall of the supply hopper on the side facing the trailer, and the other end is connected to the trailer.

[0012] Furthermore, as a preferred embodiment, the auxiliary adjustment assembly also includes a soil covering component connecting rod fixedly mounted on the side of the mounting frame away from the trailer, the soil covering component connecting rod being used to fix the soil covering component.

[0013] Furthermore, as a preferred embodiment, the feeder assembly has corresponding deep loosening components arranged in the front auxiliary material bin and the rear auxiliary material bin, and the feeder assembly includes a hinged seat connected to the lower output end of the front auxiliary material bin and the rear auxiliary material bin. A conveying switch is installed in the hinged seat, and a feed pipe is extended from the lower end of the hinged seat. A blocker is installed at the lower end of the feed pipe. The blocker is inclined and has a connection hole at the front end, which can be temporarily fixedly connected to the connecting hole on the soil breaking component.

[0014] Compared with the prior art, this application provides a high-efficiency soil loosening and fertilization compound machinery, which has the following beneficial effects: In this application, granular fertilizer is first pre-filled into the feeding hopper. After the trailer starts, the vibration it generates is transmitted to the feeding hopper through an auxiliary connecting rod. The auxiliary connecting rod serves two purposes: firstly, to fix the feeding hopper, and secondly, to facilitate vibration transmission, thus aiding in the stratification of the fertilizer. Under the action of vibration, the granular fertilizer stratifies itself according to its different specific gravities. Other areas of the feeding port on the side wall of the feeding hopper are blocked by baffles, thereby restricting the internal connection of the feeding hopper to the front conveying pipe only through a movable leakage chute, which transports the fertilizer to the front auxiliary hopper. Then, the control switch is turned on, allowing the stratified fertilizer to enter the temporary storage spaces of the front and rear auxiliary hoppers respectively, ensuring the uniformity of the fertilizer entering the two hoppers. Before the fertilizer enters the auxiliary material silo, the particle size of different batches of fertilizer entering the front and rear auxiliary material silos is measured and counted by a particle size monitor for subsequent quantitative control. In addition, the hot air blower supplies hot air from bottom to top into the feeding silo through the hot air interface to reduce the humidity inside the silo and prevent fertilizer from caking. At the same time, the vibration also plays a role in self-cleansing the fertilizer, further improving the uniformity of the fertilizer. The trailer pulls the deep loosening component to loosen the soil. The front auxiliary material silo supplies fertilizer first. The system will control the rear auxiliary silo to coordinate and supplement the fertilizer supply based on the trailer's travel speed, loosening depth, and the amount of material in the front and rear auxiliary material silos. This achieves deep loosening, layered fertilization, and soil covering in one go, improving work efficiency. Attached Figure Description

[0016] Please see Figures 1-6 In this embodiment of the application, a high-efficiency soil loosening and fertilization compound machinery includes a trailer 1, a deep loosening component 2, a fertilizer supply component 3, an auxiliary adjustment component 4, and a hot air blower 5. The deep loosening component 2 is mounted on the rear end of the trailer 1. The deep loosening component 2, the auxiliary adjustment component 4, and the fertilizer supply component 3 are stacked sequentially. The fertilizer supply component 3 includes a feeding bin 31, with a bottom feeding port 33 at the bottom end of the feeding bin 31. A side feeding port 34 is provided on the side wall of the feeding bin 31 facing the trailer 1. A hot air interface is provided on the side wall of the feeding bin 31 near the bottom feeding port 33. 35. The auxiliary adjustment component 4 includes a fixed frame 41 fixed to the upper end of the deep loosening component 2. The upper end of the fixed frame 41, away from the trailer 1, is provided with a front auxiliary material bin 42 and a rear auxiliary material bin 43. The lower ends of the front auxiliary material bin 42 and the rear auxiliary material bin 43 are provided with multiple feeder groups 46. The upper input port of the front auxiliary material bin 42 is connected to the side wall feed port 34 through the front feed pipe 45. The upper input port of the rear auxiliary material bin 43 is connected to the bottom feed port 33. The fixed frame 41 is also provided with a hot air blower 5. The output end of the hot air blower 5 is connected to the hot air interface 35.

[0017] It needs to be explained that the feeding hopper 31 is pre-filled with granular fertilizer. The vibration transmitted to the feeding hopper 31 by the start of the trailer 1 causes the granular fertilizer to stratify according to different specific gravities. Granular fertilizer of different particle sizes is stored in the front auxiliary hopper 42 and the rear auxiliary hopper 43 respectively. Subsequently, the trailer 1 drags the deep loosening component 2 to loosen the soil. The front auxiliary hopper 42 is given priority in supplying fertilizer. During this period, the rear auxiliary hopper 43 is controlled to supplement and coordinate the supply of fertilizer based on the travel speed of the trailer 1, the loosening depth, and the amount of material stored in the front auxiliary hopper 42 and the rear auxiliary hopper 43. In addition, during the operation, the hot air blower 5 supplies hot air to the feeding hopper 31 from bottom to top through the hot air interface 35 to reduce the humidity in the feeding hopper 31 and prevent the fertilizer from caking. At the same time, the vibration helps to improve the uniformity of the fertilizer.

[0018] In a preferred embodiment, both the pre-feeder silo 42 and the post-feeder silo 43 are provided with temporary storage space. The pre-feeder conveying pipe 45 is made of soft material. The upper input port of the post-feeder silo 43 is loosely connected to the lower feed port 33. Control switches are provided between the pre-feeder silo 42 and the pre-feeder conveying pipe 45, and between the upper end of the post-feeder silo 43 and the lower feed port 33. The control switches are equipped with particle size monitors.

[0019] It needs to be explained that the control switch is turned on after the fertilizer is uniformly layered by vibration. This is mainly to ensure the uniformity of the fertilizer entering the temporary storage space inside the pre-auxiliary material silo 42 and the post-auxiliary material silo 43. During this period, the particle size of different batches of fertilizer entering the pre-auxiliary material silo 42 and the post-auxiliary material silo 43 is measured and counted by the particle size monitor, which facilitates the quantitative control of fertilizer supply during operation.

[0020] In a preferred embodiment, the subsoil assembly 2 includes a support frame 21 connected to the trailer 1 via an auxiliary connecting frame 24, and a plurality of subsoil shovel assemblies 22 are fixedly mounted on the lower end of the support frame 21 via a fastener 23.

[0021] In a preferred embodiment, the subsoil shovel assembly 22 is arranged in two rows, corresponding to the front auxiliary material bin 42 and the rear auxiliary material bin 43.

[0022] In a preferred embodiment, the deep loosening shovel assembly 22 includes a connecting seat 221 connected to the fixing member 23. A boom 222 extends from the lower end of the connecting seat 221. A soil-dividing shovel 223 is fixedly inclined at the lower end of the boom 222. A groove is opened at the lower end of the boom 222. A soil-breaking component 224 is arranged in the groove. Multiple through holes are evenly distributed near the rear end of the soil-breaking component 224. The soil-breaking component 224 and the boom 222 are temporarily fixed by bolts and through holes.

[0023] It should be explained that the trailer 1 drives the deep loosening component 2 to loosen the soil. During this process, the deep loosening shovel group 22 breaks the soil to form a loosening trench, which facilitates subsequent fertilization.

[0024] In a preferred embodiment, the fertilizer supply assembly 3 further includes a movable material leakage trough 36 that is slidably disposed on the inner wall of the feeding bin 31. The sliding area of ​​the movable material leakage trough 36 corresponds to the side wall feeding port 34, and a baffle that fits against the inner wall of the feeding bin 31 is fixedly disposed around the movable material leakage trough 36.

[0025] It should be explained that the baffle blocks other areas of the side wall feeding port 34, restricting the internal connection of the feeding hopper 31 to the front conveying pipe 45 only through the movable material leakage trough 36.

[0026] In a preferred embodiment, the fertilizer supply assembly 3 also includes an auxiliary connecting rod 32, one end of which is hinged to the side of the outer wall of the feeding bin 31 facing the trailer 1, and the other end is connected to the trailer 1.

[0027] It should be explained that the auxiliary connecting rod 32 helps to fix the feeding bin 31 on the one hand, and promotes the transmission of vibration to the feeding bin 31 to assist the fertilizer in stratification on the other hand.

[0028] In a preferred embodiment, the auxiliary adjustment assembly 4 also includes a soil covering member connecting rod 44 fixedly disposed on the side of the fixing frame 41 away from the trailer 1, the soil covering member connecting rod 44 being used to fix the soil covering member.

[0029] It should be explained that the installation of the soil covering component can complete deep loosening, layered fertilization, and soil covering in one go, improving work efficiency.

[0030] In a preferred embodiment, the feeder group 46 arranges corresponding deep loosening components 2 in the front auxiliary material bin 42 and the rear auxiliary material bin 43, and the feeder group 46 includes a hinge seat 461 connected to the lower output end of the front auxiliary material bin 42 and the rear auxiliary material bin 43. A conveying switch is installed in the hinge seat 461, and a feed pipe 462 extends from the lower end of the hinge seat 461. A blocker 463 is provided at the lower end of the feed pipe 462. The blocker 463 is inclined and has a connection hole at its front end, which can be temporarily fixedly connected to the connecting hole on the soil breaking component 224.

[0031] In practice, granular fertilizer is first pre-filled into the feeding hopper 31. After the trailer 1 starts, the vibration it generates is transmitted to the feeding hopper 31 through the auxiliary connecting rod 32. The auxiliary connecting rod 32 is used to fix the feeding hopper 31 on the one hand, and to promote the transmission of vibration on the other hand, so as to assist the fertilizer to stratify. Under the action of vibration, the granular fertilizer will stratify itself according to different specific gravities. Other areas of the side wall feeding port 34 of the feeding hopper 31 are blocked by baffles, thus restricting the internal connection of the feeding hopper 31 to the front conveying pipe 45 only through the movable leakage chute 36, so as to transport the fertilizer to the front auxiliary hopper 42. Then, the control switch is turned on so that the stratified fertilizer enters the temporary storage space of the front auxiliary hopper 42 and the rear auxiliary hopper 43 respectively, ensuring that the fertilizer enters the two hoppers. The uniformity of the fertilizer is improved. Before the fertilizer enters the auxiliary material silo, the particle size of different batches of fertilizer entering the front auxiliary material silo 42 and the rear auxiliary material silo 43 is measured and counted by the particle size monitor for subsequent quantitative control. In addition, the hot air blower 5 supplies hot air from bottom to top into the feeding silo 31 through the hot air interface 35 to reduce the humidity in the silo and prevent the fertilizer from caking. At the same time, the vibration also plays a role in self-rubbing the fertilizer, further improving the uniformity of the fertilizer. The trailer 1 drags the deep loosening component 2 to loosen the soil. The front auxiliary material silo 42 prioritizes the supply of fertilizer. The system will control the rear auxiliary material silo 43 to coordinate and supplement the supply of fertilizer according to the trailer 1's travel speed, loosening depth and the amount of material in the front and rear auxiliary material silos. This achieves deep loosening, layered fertilization and soil covering in one go, improving the efficiency of operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
