Description

Technical Field

[0001] This invention relates to the field of fertilizer applicator technology, and in particular to a biogas slurry fertilizer applicator with multiple usage modes. Background Technology

[0002] Biogas slurry is rich in nutrients such as nitrogen, phosphorus, potassium, sodium, and calcium. In addition to these components, biogas residue also contains organic matter and humic acid, thus biogas slurry can be used as fertilizer. In the prior art, patent CN219812521U discloses a liquid fertilizer spreader, which includes a frame, a tank, and a spraying mechanism. A high-pressure pump pumps liquid from the tank and sprays it onto the field through the spraying mechanism. To increase the working width, CN210782058U discloses a mobile fertilizer spreader with a foldable spreading mechanism. Furthermore, patent CN210928600U discloses a concentrated liquid spraying mechanism that can disperse the liquid, using a rotating spraying roller to spread the fertilizer and improve the uniformity of application. All of the above patents suffer from the drawback of having a single operating mode for the fertilizer spreader, making it difficult to change the fertilization mode according to fertilization needs. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a multi-mode biogas slurry fertilizer applicator with diverse usage modes and convenient switching between usage modes.

[0004] Technical solution: To achieve the above objectives, the present invention provides a multi-mode biogas slurry fertilizer applicator, which includes a mobile base on which a biogas slurry fertilizer tank and a fertilizer applicator are mounted. The fertilizer applicator includes a frame and multiple fertilizer spreading units arranged in an array on the frame. Each fertilizer spreading unit includes a delivery pipe and a spray pipe. The biogas slurry fertilizer tank is connected to each delivery pipe via a pump.

[0005] The fertilizer spreading unit also includes a swinging component rotatably mounted on the spray pipe. The swinging component includes a baffle that can swing up and down and a rotating frame connected to the spray pipe.

[0006] The frame is also equipped with a slide rail and a sliding seat that can slide along the slide rail; each of the rotating frames is connected to the sliding seat with a pull wire; the frame is also equipped with a telescopic mechanism located under the sliding seat, and the telescopic rod of the telescopic mechanism can switch between an extended state and a retracted state; when the telescopic rod is in the extended state, it can restrict the sliding of the sliding seat.

[0007] With the above structure, when the infusion pipe is in an upright position, all fertilizer application units can simultaneously switch between direct injection mode and spread mode. In direct injection mode, the telescopic rod of the telescopic mechanism extends, raising the sliding seat to a high position. In this way, the sliding seat does not pull on the baffle, the baffle is in a low position, and the liquid delivered by the infusion pipe is directly sprayed out from the spray pipe in the form of a water column.

[0008] In the spreading mode, the telescopic rod of the telescopic mechanism retracts, allowing the sliding seat to slide freely. When the sliding seat descends under its own weight, it pulls the swinging component to rotate, causing the baffle to rise. When the baffle moves to the front of the nozzle of the spray pipe, it strikes the liquid column sprayed from the spray pipe, causing the sprayed biogas slurry fertilizer to be dispersed into many scattered water droplets, which can improve the uniformity of fertilizer spreading. At the same time, the liquid sprayed from the spray pipe pushes the baffle, causing the baffle to rotate downwards. The resultant force of many baffles being pushed downwards by the liquid is transmitted to the sliding seat through the pull line, causing the sliding seat to rise. After the rising speed of the sliding seat drops to 0, it descends again and pulls the corresponding swinging component to rotate through the pull line, causing the baffle to strike the liquid sprayed from the spray pipe again. This process is repeated, and the baffle can intermittently strike the liquid sprayed from the spray pipe at very short time intervals, thereby improving the uniformity and coverage of fertilizer spreading.

[0009] Preferably, in the spreading mode, when the baffle reaches the front end of the spray pipe, the baffle is inclined relative to the axis of the spray pipe, and its upper edge is far from the outlet of the spray pipe, while its lower edge is close to the outlet of the spray pipe. In this way, while the baffle strikes the liquid sprayed from the spray pipe, it can also guide the liquid sprayed from the spray pipe, so that the biogas slurry fertilizer can be spread to a farther place, increasing the spraying distance.

[0010] In addition, the edge of the baffle near the nozzle has a limiting part. When the baffle reaches the front end of the nozzle, the limiting part of the baffle abuts against the lower edge of the nozzle to prevent over-movement.

[0011] Furthermore, counterweights can be added or removed from the sliding seat. By adding or removing counterweights, the overall mass of the sliding seat and counterweights can be adjusted, thereby adjusting the impact force of the baffle on the liquid column and the impact time interval, that is, adjusting the impact frequency.

[0012] Furthermore, the frame is composed of three sub-frames, which are rotatably connected in sequence, with the middle sub-frame fixedly installed relative to the movable base; the frame can switch between an unfolded state and a folded state. In the unfolded state, all the sub-frames are collinear, and in the folded state, all the sub-frames are arranged in a U-shape around the biogas slurry fertilizer tank.

[0013] Furthermore, each of the sub-frames is equipped with the fertilizer spreading unit, the slide rail, and the sliding seat; the swinging component corresponding to the fertilizer spreading unit on each of the sub-frames is connected to the sliding seat on that sub-frame.

[0014] Furthermore, a first hydraulic cylinder is connected between two adjacent sub-frames to drive their relative rotation. This first hydraulic cylinder not only automatically switches the frame between a folded state and a rotating state, but also freely adjusts the angle between adjacent sub-frames as needed to meet specific fertilization requirements. Each sub-frame is equipped with a rotating frame, and all the fertilizer applicators corresponding to each sub-frame are mounted on the rotating frame. A second hydraulic cylinder is connected between each sub-frame and its corresponding rotating frame to drive their relative rotation. The second hydraulic cylinder allows for flexible adjustment of the tilt angle of the rotating frame relative to the sub-frame. The infusion pipe can not only spray liquid upwards to a distance, but also hang downwards with the rotating frame, allowing its outlet pipe to directly irrigate the ground. Thus, the biogas slurry fertilizer applicator of this invention has another usage mode.

[0015] Furthermore, the pull wire includes a sleeve and a wire core. The two ends of the sleeve are respectively fixed to the ejector pipe and the sub-frame. The wire core passes through the sleeve, and the two ends of the wire core are respectively fixed to the swing component and the sliding seat.

[0016] Furthermore, a stop block is also installed on the sub-frame above the sliding seat. When the telescopic rod extends, the sliding seat is pressed between the stop block and the telescopic rod to fix the sliding seat in the direct injection mode.

[0017] Beneficial effects: The multi-mode biogas slurry fertilizer applicator of the present invention has the following effects:

[0018] (1) By interacting with the baffle and the sliding seat, and by utilizing the force of the water jet from the spray pipe, the baffle can intermittently act on the water jet from the spray pipe. The fertilization state can be switched by whether the telescopic mechanism restricts the movement of the sliding seat. Overall, the above structure is simple. The reciprocating swing motion of each swinging component cleverly utilizes the power of water, eliminating the need for a separate drive component and greatly saving costs.

[0019] (2) The frame can be folded and unfolded. When the frame is unfolded, the working width can be greatly increased, improving work efficiency. When the frame is folded, the angle of fertilizer spreading can be increased, enabling simultaneous spreading of fertilizer from multiple sides. In addition, the width of the frame is greatly reduced when folded, which can improve the overall passability of the fertilizer spreader.

[0020] (3) The pitch angle of the rotating frame relative to the sub-frame can be flexibly adjusted by the second oil cylinder. The infusion pipe can not only stand up and spray liquid to a distance, but also hang down with the rotating frame, so that its spray pipe can directly irrigate the ground.

[0021] (4) The baffle is driven by a wire structure, and the linkage between the swinging component and the sliding seat is not affected by the pitch angle of the rotating frame. Attached Figure Description

Detailed Implementation

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] like Figure 1The multi-mode biogas slurry fertilizer applicator shown includes a mobile base 6, on which a biogas slurry fertilizer tank 1 and a fertilization mechanism are installed. The fertilization mechanism includes a frame 2 and multiple fertilizer spreading units 3 arranged in an array on the frame 2. Each fertilizer spreading unit 3 includes an infusion pipe 31 and a spray pipe 32. The biogas slurry fertilizer tank 1 is connected to each of the infusion pipes 31 through a pump.

[0034] like Figure 2 As shown, the fertilizer spreading unit 3 also includes a swinging component 33 rotatably mounted on the spray pipe 32. The swinging component 33 includes a baffle 33a that can swing up and down and a rotating frame 33b connected to the spray pipe 32.

[0035] like Figure 4-5 As shown, the frame 2 is also equipped with a slide rail 41 and a sliding seat 42 that can slide along the slide rail 41; each of the rotating frames 33b is connected to the sliding seat 42 by a pull wire 43; the frame 2 is also equipped with a telescopic mechanism 5 located on the lower side of the sliding seat 42, and the telescopic rod of the telescopic mechanism 5 can switch between an extended state and a retracted state; when the telescopic rod is in the extended state, it can restrict the sliding of the sliding seat 42.

[0036] Using the above structure, when the infusion tube 31 is in an upright position, all fertilizer application units 3 can simultaneously switch between direct injection mode and spread mode. In direct injection mode, the telescopic rod of the telescopic mechanism 5 extends, raising the sliding seat 42 to a high position. Thus, the sliding seat 42 does not pull on the baffle 33a, and the baffle 33a is in a low position (e.g., Figure 3 As shown in the figure, the liquid transported by the infusion tube 31 is directly sprayed out from the spray tube 32 in the form of a water column.

[0037] In the scattering mode, the telescopic rod of the telescopic mechanism 5 retracts, allowing the sliding seat 42 to slide freely; when the sliding seat 42 descends under its own weight, it pulls the swing component 33 to rotate, causing the baffle 33a to rise, as... Figure 2 As shown, when the baffle 33a moves to the front of the nozzle of the spray pipe 32, it strikes the liquid column sprayed from the spray pipe 32, causing the sprayed biogas slurry fertilizer to be dispersed into many scattered water droplets, which can improve the uniformity of fertilizer application. At the same time, the liquid sprayed from the spray pipe 32 pushes the baffle 33a, causing the baffle 33a to rotate downward. The resultant force of many baffles 33a being pushed downward by the liquid is transmitted to the sliding seat 42 through the pull line 43, causing the sliding seat 42 to rise. After the rising speed of the sliding seat 42 drops to 0, it falls again and pulls the corresponding swing component 33 to rotate through the pull line 43, causing the baffle 33a to strike the liquid sprayed from the spray pipe 32 again. This process is repeated, and the baffle 33a can intermittently strike the liquid sprayed from the spray pipe 32 at very short time intervals to improve the uniformity and coverage of fertilizer application.

[0038] In the above structure, the interaction between the baffle 33a and the sliding seat 42, and the force of the water jet ejected from the spray pipe 32, allows the baffle 33a to intermittently act on the water jet ejected from the spray pipe 32. The switching of the fertilization state is achieved by using the telescopic mechanism 5 to restrict the movement of the sliding seat 42. Overall, the structure is simple, and the reciprocating oscillation motion of each swinging component 33 cleverly utilizes the power of water, eliminating the need for a separate drive component and significantly reducing costs.

[0039] Preferably, in the dispersion mode, when the baffle 33a reaches the front end of the spray pipe 32, the baffle 33a is inclined relative to the axial direction of the spray pipe 32 (e.g., Figure 2 As shown in the figure, its upper edge is far from the outlet of the spray pipe 32, and its lower edge is close to the outlet of the spray pipe 32. In this way, while the baffle 33a strikes the liquid sprayed from the spray pipe 32, it can also guide the liquid sprayed from the spray pipe 32, so that the biogas slurry fertilizer can be spread to a farther place and increase the spraying distance.

[0040] In addition, the edge of the baffle 33a near the nozzle 32 has a limiting part b. When the baffle 33a reaches the front end of the nozzle 32, the limiting part b of the baffle 33a abuts against the lower edge of the nozzle 32 to prevent over-movement.

[0041] Preferably, the counterweight 44 can be added or removed from the sliding seat 42. By adding or removing the counterweight 44, the overall mass of the sliding seat 42 and the counterweight can be adjusted, thereby adjusting the impact force of the baffle 33a on the liquid column and adjusting the impact time interval, that is, adjusting the impact frequency.

[0042] Preferably, the frame 2 is composed of three sub-frames 21, which are rotatably connected in sequence, with the middle sub-frame 21 fixedly installed relative to the movable base 6; the frame 2 can switch between an unfolded state and a folded state, such as... Figure 1 As shown, in the unfolded state, all the sub-frames 21 are collinear, as... Figure 6 As shown, in the folded state, all the sub-frames 21 are arranged in a U-shape around the biogas slurry fertilizer tank 1. With this structure, when the frame 2 is in the unfolded state, the working width can be significantly increased, improving work efficiency. When the frame 2 is in the folded state, the angle of fertilizer application can be increased, enabling simultaneous application from multiple sides. Furthermore, in the folded state, the width of the frame 2 is significantly reduced, improving the overall maneuverability of the fertilizer applicator.

[0043] Preferably, each of the sub-frames 21 is equipped with the fertilizer spreading unit 3, the slide rail 41, and the sliding seat 42; the swinging component 33 corresponding to the fertilizer spreading unit 3 on each of the sub-frames 21 is connected to the sliding seat 42 on the sub-frame 21.

[0044] Preferably, such as Figure 9 As shown, a first hydraulic cylinder 22 is connected between two adjacent sub-frames 21 to drive their relative rotation; the first hydraulic cylinder 22 can not only drive the frame 2 to automatically switch between folded and rotating states, but also freely adjust the angle between adjacent sub-frames 21 as needed to meet special fertilization requirements. Figure 8 As shown, each of the sub-frames 21 is equipped with a rotating frame 23, and all the fertilizer spreading units 3 corresponding to the sub-frames 21 are mounted on the rotating frame 23. A second hydraulic cylinder 24 is connected between the sub-frame 21 and its corresponding rotating frame 23 to drive the two to rotate relative to each other. The second hydraulic cylinder 24 can flexibly adjust the pitch angle of the rotating frame 23 relative to the sub-frame 21. The infusion pipe 31 can not only stand upright and spray liquid to a distance, but also hang downward with the rotating frame 23, so that its spray pipe 32 can directly irrigate the ground. In this way, the biogas slurry fertilizer applicator of the present invention has another mode of use.

[0045] Preferably, the pull wire 43 includes a sleeve 431 and a wire core 432. The two ends of the sleeve 431 are respectively fixed to the ejector pipe 32 and the sub-frame 21. The wire core 432 passes through the sleeve 431, and its two ends are respectively fixed to the swing component 33 and the sliding seat 42. Thus, the linkage between the swing component 33 and the sliding seat 42 is not affected by the pitch angle of the rotating frame 23.

[0046] Preferably, the sub-frame 21 is also equipped with a stop 52 located above the sliding seat 42. When the telescopic rod extends, the sliding seat 42 is pressed between the stop 52 and the telescopic rod to fix the sliding seat 42 in the direct injection mode.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
