Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a pellet fertilizer applicator. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide the nutrients they need and to maintain and improve soil fertility. Using fertilizer applicators to apply granular fertilizer reduces the intensity of manual labor.

[0003] Traditional fertilizer applicators typically spread fertilizer on the ground to increase soil fertility. However, some farmers need to apply fertilizer into furrows, which is difficult for traditional fertilizer applicators to do. Furthermore, traditional fertilizer applicators usually use motors or other power devices to drive a conveying device to transport fertilizer from the fertilizer tank to the ground to complete the fertilization work. However, both motors and other power devices increase energy consumption and raise manufacturing costs. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a granular fertilizer applicator with a reasonable structure that does not require a power unit and can apply fertilizer into trenches.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A granular fertilizer applicator includes a frame, with two symmetrically arranged conveying devices fixedly connected to the rear end of the frame in the forward direction. A fertilizer box assembly is arranged above the two conveying devices, and a feeding amount control assembly is arranged between the fertilizer box assembly and the two conveying devices. A plow assembly is arranged at the far end of each of the two conveying devices. A rotating shaft is rotatably connected to the bottom of the frame, and both ends of the rotating shaft are provided with traveling wheels. A transmission device for driving the two conveying devices is arranged between the rotating shaft and the two conveying devices.

[0007] The following are further optimizations of the above technical solution by this utility model:

[0008] The material conveying device includes a material conveying cylinder, which is fixedly connected to the frame. The top surface of the material conveying cylinder away from the plow assembly has a feed inlet, and the bottom surface of the material conveying cylinder near the plow assembly has a discharge outlet.

[0009] Further optimization: Both feed cylinders are rotatably connected to auger shafts, and auger blades are fixedly connected to both auger shafts. The two auger blades rotate in opposite directions, and the ends of the two auger shafts that are close to each other extend to the outside of their corresponding feed cylinders and are connected to the transmission device.

[0010] Further optimization: The fertilizer box assembly includes a fertilizer box with two discharge ports on the bottom surface. The two discharge ports and two feed ports are set accordingly. A box frame is fixedly connected to the bottom of the fertilizer box, and the box frame is fixedly set above the discharge amount control component.

[0011] Further optimization: The material feeding control component includes a support frame, which is fixed above the two material conveying cylinders. A box frame is fixed above the support frame. Two material feeding slots are opened on the box frame, and the two material feeding slots are set with two material feeding ports corresponding to each other. A material feeding control plate is slidably connected in both material feeding slots.

[0012] Further optimization: The support frame includes a first support plate, which is fixed above the two conveying cylinders. The first support plate has two material passages, which are correspondingly set with the two discharge ports.

[0013] Further optimization: Two second support plates are fixed to the first support plate. Each of the two second support plates has a first threaded hole. Each of the two feeding control plates has an elongated hole. The two elongated holes and the two first threaded holes are set accordingly.

[0014] Further optimization: The plow blade assembly includes a connecting frame, which is fixedly connected to its corresponding feed cylinder. A mounting bracket is fixedly connected to the connecting frame, and a plow blade is slidably connected inside the mounting bracket.

[0015] Further optimization: The transmission device includes a drive sprocket, which is fixedly connected to the rotating shaft. The driven sprocket is fixedly connected to one end of the two auger shafts that are close to each other. A chain is sleeved between the drive sprocket and the driven sprocket.

[0016] Further optimization: The walking wheel includes a wheel body, which is fixedly connected to the axle. Multiple gripping plates are fixedly attached to the outer circumference of the wheel body, and the multiple gripping plates are arranged in a ring around the outer circumference of the wheel body.

[0017] This utility model, through its rational design, allows the fertilizer applicator to move forward. The rotating wheels drive two auger shafts via a transmission device, which in turn transports fertilizer from the fertilizer bin to the opposite ends of two feed cylinders, discharging it into the furrows plowed by the plow blades. This eliminates the need for a power unit, reducing energy consumption. The linkage between the feed device and the rotating wheels ensures more even fertilizer application. Adjusting the feed rate control component allows for precise control of the fertilizer output from the fertilizer bin, effectively managing the amount of fertilizer applied to different plots.

Detailed Implementation

[0028] like Figure 1-8 As shown: A granular fertilizer applicator includes a frame 1. Two symmetrically arranged material conveying devices 2 are fixedly connected to the rear end of the frame 1 in the forward direction. A fertilizer box assembly 3 is arranged above the two material conveying devices 2. A feeding amount control assembly 4 is arranged between the fertilizer box assembly 3 and the two material conveying devices 2. A plow assembly 5 is arranged at the ends of the two material conveying devices 2 that are far apart from each other. A rotating shaft 6 is rotatably connected to the bottom of the frame 1. Both ends of the rotating shaft 6 are provided with traveling wheels 7. A transmission device 8 for driving the two material conveying devices 2 is arranged between the rotating shaft 6 and the two material conveying devices 2.

[0029] With this design, the rotation of the two walking wheels 7 drives the material conveying device 2, which facilitates the transport of fertilizer from the fertilizer box assembly 3 to the furrow plowed by the plow blade assembly 5, eliminating the need for a power unit and reducing energy consumption.

[0030] The material conveying device 2 includes a material conveying cylinder 201, which is fixedly connected to the frame 1. The top surface of the material conveying cylinder 201 away from the plow assembly 5 has a feed inlet 2011, and the bottom surface of the material conveying cylinder 201 near the plow assembly 5 has a discharge outlet 2012.

[0031] Both conveying cylinders 201 are rotatably connected to auger shafts 202, and auger blades are fixedly connected to both auger shafts 202. The two auger blades rotate in opposite directions, and the ends of the two auger shafts 202 that are close to each other extend to the outside of their corresponding conveying cylinders 201 and are connected to the transmission device 8.

[0032] With this design, the auger shaft 202 drives the auger blades to rotate, which facilitates the transfer of fertilizer from the feed inlet 2011 into the feed cylinder 201 to the discharge outlet 2012.

[0033] The fertilizer box assembly 3 includes a fertilizer box 301. The bottom surface of the fertilizer box 301 has two discharge ports 3011. The two discharge ports 3011 and two feed ports 2011 are correspondingly arranged. A box frame 302 is fixedly connected to the bottom of the fertilizer box 301. The box frame 302 is fixedly arranged above the discharge quantity control assembly 4.

[0034] The material feeding control component 4 includes a support frame 401, which is fixed above the two material conveying cylinders 201. A box frame 302 is fixed above the support frame 401. Two material feeding slots 3021 are provided on the box frame 302. The two material feeding slots 3021 are correspondingly arranged with two material feeding ports 3011. A material feeding control plate 402 is slidably connected in each of the two material feeding slots 3021.

[0035] This design allows for easy sealing of the discharge port 3011 by adjusting the position of the discharge control plate 402, and also facilitates control of the fertilizer output from the discharge port 3011.

[0036] The support frame 401 includes a first support plate 4011, which is fixed above the two conveying cylinders 201. The first support plate 4011 has two material passages 4012, which are correspondingly arranged with the two discharge ports 3011.

[0037] Two second support plates 4013 are fixedly connected to the first support plate 4011. Each of the two second support plates 4013 has a first threaded hole 4014. Each of the two feeding control plates 402 has an elongated hole 4021. The two elongated holes 4021 and the two first threaded holes 4014 are set accordingly.

[0038] With this design, the first threaded hole 4014 is internally threaded with a handle screw. After adjusting the position of the feed quantity control plate 402, tightening the handle screw makes it easy to fasten the feed quantity control plate 402 to the support frame 401. The elongated hole 4021 facilitates the adjustment of the position of the feed quantity control plate 402.

[0039] The plow assembly 5 includes a connecting frame 501, which is fixedly connected to its corresponding feed cylinder 201. A mounting frame 503 is fixedly connected to the connecting frame 501 via a connecting plate 502, and a plow blade 504 is slidably connected inside the mounting frame 503.

[0040] This design allows for easy adjustment of the height of the plow blade 504, thereby adjusting the depth of the furrows plowed by the plow blade 504.

[0041] A second threaded hole 5031 is provided on the side wall of the mounting bracket 503, and a locking screw is connected to the internal thread of the second threaded hole 5031.

[0042] With this design, after adjusting the height of the plow blade 504, tightening the locking screws makes it easy to fix the plow blade 504 onto the feed cylinder 201.

[0043] The two plow blades 504 are respectively positioned opposite the two discharge ports 2012, so that the fertilizer discharged from the discharge ports 2012 can fall into the furrows plowed by the plow blades 504.

[0044] Each of the two connecting frames 501 has a support rod 9 fixedly connected to one end of each other. The other end of the support rod 9 is fixedly connected to the frame 1, which increases both the strength of the frame 1 and the stability of the connecting frame 501 installation.

[0045] The transmission device 8 includes a drive sprocket 801, which is fixedly connected to the rotating shaft 6. The driven sprocket 802 is fixedly connected to one end of the two auger shafts 202 that are close to each other. A chain is sleeved between the drive sprocket 801 and the driven sprocket 802.

[0046] With this design, the rotation of the walking wheel 7 drives the rotating shaft 6, which in turn drives the two auger shafts 202 to rotate through the transmission device 8. The fertilizer in the fertilizer box 301 is then transported to the two conveying cylinders 2 at opposite ends for discharge through the two auger blades rotating in opposite directions. Furthermore, the rotation speed of the two auger shafts 202 is linked to the speed of the walking wheel 7. The faster the fertilizer applicator moves, the faster the conveying device 2 delivers fertilizer, which is beneficial for the uniform application of fertilizer.

[0047] In this embodiment, both the driving sprocket 801 and the driven sprocket 802 are double-row sprockets, and the chain is a double-row chain.

[0048] In addition to this embodiment, the driving sprocket 801 and the driven sprocket 802 can also be single-row sprockets, the chain can also be a single-row chain, and the rotating shaft 6 can also transmit power to the two auger shafts 202 through other transmission methods such as belt drive.

[0049] The walking wheel 7 includes a wheel body 701, which is fixedly connected to the axle 6. Multiple gripping plates 702 are fixedly attached to the outer circular surface of the wheel body 701, and the multiple gripping plates 702 are arranged in a ring around the outer circular surface of the wheel body 701.

[0050] This design prevents the walking wheels 7 from slipping during the fertilizer applicator's movement.

[0051] In use, the frame 1 is connected to the rear of the tractor. The tractor pulls the fertilizer applicator. As the fertilizer applicator moves forward, the traveling wheels 7 rotate and drive the two auger shafts 202 to rotate through the transmission device 8. Then, the fertilizer in the fertilizer box 301 is transported to the two feed cylinders 2 at opposite ends and discharged into the furrow plowed by the plow blades 504. No power device is required, which reduces energy consumption.

[0052] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
