Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rotary tiller and fertilizer applicator. Background Technology
[0002] Tillage and fertilization are core elements in agricultural production that lay the foundation for crop growth. Tillage breaks up soil compaction, loosens soil structure, and enhances soil aeration and water and fertilizer retention capacity, creating a suitable physical environment for seed germination and root development. Fertilization, on the other hand, replenishes key nutrients such as nitrogen, phosphorus, and potassium to compensate for insufficient natural soil fertility, directly affecting crop growth rate, stress resistance, and final yield and quality. The synergistic effect of these two processes directly determines the efficiency and profitability of agricultural production and is an important prerequisite for ensuring food security and sustainable agricultural development.
[0003] In traditional operation mode, rotary tillage and fertilization are mostly independent processes, requiring separate investment of rotary tillers, fertilizer applicators and other equipment. This not only increases the cost of purchasing agricultural machinery and the number of field operations, but also causes the newly turned soil to be compacted due to multiple field visits, which damages the soil aggregate structure and reduces the soil aeration and water retention capacity. Therefore, a rotary tillage and fertilizer applicator was designed. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rotary tillage and fertilizer applicator.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rotary tiller and fertilizer applicator includes a U-shaped frame. A single rotating rod is rotatably connected between the two bottom sides of the U-shaped frame. Multiple rotary tillage claws are fixedly connected at equal intervals along the circumference of the rotating rod. Arc-shaped limiting plates are bolted to both ends of the bottom of the U-shaped frame. A third sprocket is fixedly connected to one end of the rotating rod, penetrating the U-shaped frame. Support rods are fixedly connected to both ends of the top of the U-shaped frame. A material box is fixedly connected to the top of the two support rods. A top cover is rotatably mounted on the top of the material box. The bottom of the material box is inclined and has a strip-shaped discharge port. A vertical plate is fixedly connected to the bottom of the outer wall of the material box near the center of the U-shaped frame. Two fixing blocks are fixedly connected to the middle of the side of the vertical plate away from the material box. A single rotating rod is rotatably mounted on the two fixing blocks. A disc is fixedly mounted on the circumference of the rotating rod. Three arc-shaped protrusions are fixedly connected to the outer circumference of the disc. A fourth sprocket is fixedly connected to one end of the rotating rod.
[0006] Preferably, two sliding rods are slidably fitted on both sides of the vertical plate, and the vertical plate has round holes that match the four sliding rods. The four sliding rods are fixedly connected to the same L-shaped plate near the bottom outlet of the material box, and the L-shaped plate matches the outlet. The other ends of the two sliding rods on the same side are fixedly connected to the same limiting plate, and springs are fitted on the two sliding rods between the vertical plate and the L-shaped plate.
[0007] Preferably, two strip plates are fixedly connected to the middle of the side of the L-shaped plate near the vertical plate. The other ends of the two strip plates slide through the vertical plate and are rotatably connected to the same rotating roller. The vertical plate has through holes that are adapted to the strip plates, and the rotating roller is adapted to the arc-shaped protrusion.
[0008] Preferably, the U-shaped frame is fixedly connected to two connecting plates, and the top of each of the two connecting plates is fixedly connected to a fixing clamp. The two fixing clamps are fixedly connected to the same transmission protective shell. A first driven shaft is rotatably connected to one side of the inner wall of the transmission protective shell through a bearing. A first bevel gear is fixedly connected to one end of the first driven shaft located in the middle of the transmission protective shell. A second sprocket is fixedly connected to the other end of the first driven shaft through the U-shaped frame. The same first chain is sleeved between the second sprocket and the third sprocket. A sprocket protective cover is fixedly connected to the outside of the first chain.
[0009] Preferably, a second driven shaft is fixedly connected to the other end of the first driven shaft, and the second driven shaft is rotatably connected inside the transmission protective housing via a bearing, and a first sprocket is fixedly connected to the other end of the second driven shaft.
[0010] Preferably, the first sprocket and the fourth sprocket are fitted with the same second chain.
[0011] Preferably, the two connecting plates and the top of the outer wall of the transmission protective shell are fixedly installed with the same connecting frame, and a driving mechanism is also provided on the side of the top of the U-shaped frame away from the material box. The driving mechanism includes three driving shafts and two universal joints, and the three driving shafts and the three universal joints are connected in a cross sequence. The driving shaft near the transmission protective shell is fixedly connected to a second bevel gear through a bearing through the transmission protective shell, and the second bevel gear meshes with the first bevel gear.
[0012] The beneficial effects of this utility model are as follows: By employing technologies such as L-shaped plates, springs, strip plates, rotating rollers, arc-shaped protrusions, and a fourth sprocket, the L-shaped plates reciprocate as the rotary tiller turns the soil. This movement, caused by the rotation of the second chain, evenly distributes the fertilizer inside the material box under gravity, filling the gaps in the turned soil with fertilizer. This effectively solves the problem mentioned in the background technology that tilling and fertilization cannot be carried out simultaneously. Consequently, it achieves integrated rotary tillage and fertilization operations, precise and uniform fertilizer distribution, and improved fertilizer utilization efficiency. The two originally separate processes are completed simultaneously, significantly reducing the number of field operations and time costs, and improving agricultural production efficiency.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figures 1-7 A rotary tiller and fertilizer applicator includes a U-shaped frame 1. A single rotating rod 101 is rotatably connected between the two bottom sides of the U-shaped frame 1. Multiple rotary tillage claws 102 are fixedly connected at equal intervals along the circumference of the rotating rod 101. Arc-shaped limiting plates 103 are bolted to both ends of the bottom of the U-shaped frame 1. A third sprocket 115 is fixedly connected to one end of the rotating rod 101 through the U-shaped frame 1. Support rods 202 are fixedly connected to both ends of the top of the U-shaped frame 1. A material box 2 is fixedly connected to the top of the two support rods 202, and a top cover 2 is rotatably mounted on the top of the material box 2. 01, and the bottom of the material box 2 is inclined, and a strip-shaped discharge port is opened at the bottom of the material box 2. A vertical plate 4 is fixedly connected to the bottom of the outer wall of the material box 2 near the center of the U-shaped frame 1. Two fixing blocks 401 are fixedly connected to the middle of the side of the vertical plate 4 away from the material box 2. The same rotating rod 402 is rotatably sleeved on the two fixing blocks 401. A disc 403 is fixedly sleeved on the circumferential surface of the rotating rod 402. Three arc-shaped protrusions 404 are fixedly connected to the outer circumferential wall of the disc 403. A fourth sprocket 405 is fixedly connected to one end of the rotating rod 402.
[0017] In this utility model, two sliding rods 5 are slidably fitted on both sides of the vertical plate 4. The vertical plate 4 has round holes that are adapted to the four sliding rods 5. The same L-shaped plate 503 is fixedly connected to the four sliding rods 5 near the bottom discharge port of the material box 2, and the L-shaped plate 503 is adapted to the discharge port. The other end of the two sliding rods 5 on the same side is fixedly connected to the same limiting plate 502. Springs 501 are fitted on the two sliding rods 5 between the vertical plate 4 and the L-shaped plate 503. Through the reciprocating movement of the L-shaped plate 503, the discharge port at the bottom of the material box 2 is opened intermittently, so that the fertilizer is evenly spread into the ground. At the same time, the vibration caused by the resetting of the L-shaped plate 503 can also break up a small amount of clumps of fertilizer inside the material box 2.
[0018] In this utility model, two strip plates 6 are fixedly connected to the middle of the side of the L-shaped plate 503 near the vertical plate 4. The other ends of the two strip plates 6 slide through the vertical plate 4 and are rotatably connected to the same rotating roller 601. The vertical plate 4 has through holes that are adapted to the strip plates 6, and the rotating roller 601 is adapted to the arc-shaped protrusion 404. When the disc 403 rotates clockwise with the arc-shaped protrusion 404 as shown in the figure, the arc-shaped protrusion 404 will continuously push the rod rotating roller 601 to move the strip plates 6 and the L-shaped plate 503. Under the action of the spring 501, it can be reset.
[0019] In this utility model, the U-shaped frame 1 is fixedly connected to two connecting plates 104. The top of each connecting plate 104 is fixedly connected to a fixing clamp 107, and the two fixing clamps 107 are fixedly connected to the same transmission protective shell 106. The inner wall of the transmission protective shell 106 is rotatably connected to a first driven shaft 109 through a bearing. The first driven shaft 109 is fixedly connected to a first bevel gear 110 at one end located in the middle of the transmission protective shell 106. The other end of the first driven shaft 109 passes through the U-shaped frame 1 and is fixedly connected to a second sprocket 113. The second sprocket 113 and the third sprocket 115 are fitted with the same first chain 114, and the outer side of the first chain 114 is fixedly connected to a sprocket protective cover 116.
[0020] In this utility model, a second driven shaft 111 is fixedly connected to the other end of the first driven shaft 109, and the second driven shaft 111 is rotatably connected to the inside of the transmission protective shell 106 through a bearing, and a first sprocket 108 is fixedly connected to the other end of the second driven shaft 111.
[0021] In this utility model, the same second chain 406 is sleeved between the first sprocket 108 and the fourth sprocket 405.
[0022] In this utility model, the same connecting frame 105 is fixedly installed on the top of the outer wall of the two connecting plates 104 and the transmission protective shell 106. A drive mechanism 3 is also provided on the side of the top of the U-shaped frame 1 away from the material box 2. The drive mechanism 3 includes three drive shafts and two universal joints. The three drive shafts and the three universal joints are connected in a cross sequence. The drive shaft near the transmission protective shell 106 is fixedly connected to the second bevel gear 112 through the transmission protective shell 106 via a bearing. The second bevel gear 112 meshes with the first bevel gear 110. The drive mechanism 3 is the existing technology of the transmission mechanism of the existing rotary tiller, so it will not be described in detail.
[0023] Working principle: When in use, this device connects to the rear of an agricultural tractor via a connecting frame 105. Simultaneously, the outermost drive shaft of the drive mechanism 3 connects to the power output end at the rear of the agricultural tractor. Adjusting the position of the arc-shaped limit plate 103 controls the distance between the rotary tiller 102 and the ground. When the drive mechanism 3 starts rotating, power is transmitted to the second driven shaft 111 and the first driven shaft 109 via the rotary tiller 102 and the first bevel gear 110. Through the action of the first chain 114, the second sprocket 113, and the third sprocket 115, the rotating rod 101 rotates accordingly, thereby driving the multiple rotary tillers 102 to perform the following actions: Figure 1The clockwise rotation shown in the diagram begins to turn the soil. Simultaneously, if fertilizer needs to be added to the tilled land, the top cover 201 can be opened to add fertilizer into the material box 2. When the rotary tiller 102 starts working, the second driven shaft 111, the first sprocket 108, and the second chain 406 cause the rotating rod 402 to continuously rotate with the disc 403. As the disc 403 rotates with the arc-shaped protrusions 404, each arc-shaped protrusion 404, when passing the rotating roller 601, will cause the rotating roller 601 to move a certain distance, causing the L-shaped plate 503 to move and compressing the spring 501. When the arc-shaped protrusions 404 disengage from the rotating roller 601 with the rotation, the L-shaped plate 503 will automatically reset under the action of the spring 501. Thus, the discharge port at the bottom of the material box 2 will open and close intermittently, allowing an appropriate amount of fertilizer to be scattered from the ground each time the box is opened. This achieves simultaneous tilling and fertilizer distribution.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
