Description

Technical Field

[0001] The invention relates to the technical field of wheat planting and fertilization, in particular to a wheat planting and fertilization device. Background Art

[0002] Fertilization is a very important part of wheat planting, which directly affects the growth and yield of crops. In order to improve the efficiency and accuracy of fertilization, various fertilization devices are used in modern agriculture.

[0003] The fertilization device is usually mounted on a tractor or other tractor to spread fertilizer in the trenches. During the process, the fertilizer is applied to the soil surface after the trenching by a tube connected to the hopper.

[0004] (1) There is a certain distance between the guide tube and the soil surface, and the fertilizer is directly spread on the soil surface after the trench is opened. The fertilizer is relatively dispersed on the soil surface. As the traction vehicle moves forward and is affected by external environmental factors, the concentration of fertilizer application is affected;

[0005] (2) In order to meet the requirements of centralized fertilization, the distance from the soil surface needs to be shortened. As a result, the possibility of the catheter adhering to the soil during fertilization is greatly increased, which indirectly causes a large amount of soil to adhere to the catheter mouth, which is not conducive to the smooth outflow of fertilizer.

[0006] In order to solve the above problems, we propose a wheat planting and fertilizing device. Summary of the Invention

[0065] To facilitate understanding of the technical means, creative features, objectives, and effects achieved by the present invention, the present invention will be further described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0066] [Example 1]

[0067] In order to address the shortcomings of existing technologies, such as Figure 1 、 2As shown, the present invention provides a wheat planting and fertilizing device, including a material distribution vehicle 2 for intermittent material discharging, the material distribution vehicle 2 is attached with a furrowing disc 3, and is characterized in that: a feeding assembly 4 is provided on the side of the material distribution vehicle 2 away from the furrowing disc 3; a plurality of material distribution vehicles 2 are fixedly connected to a traction frame 1, the traction frame 1 is externally connected to a traction vehicle, and the feeding assembly 4 is connected and communicated with the material distribution vehicle 2.

[0068] It should be noted that the fertilizer is filled into the material distributor 2 by connecting the traction frame 1 to a traction vehicle. In the process of fertilizing wheat, the material distributor 2 is pulled by the traction vehicle for synchronous movement. In the process of the movement of the material distributor 2, the material distributor mechanism on the material distributor 2 is started synchronously. At the same time, the movement of the material distributor 2 will drive the ditching disc 3 to directly act on the soil layer to realize ditching. Afterwards, the material distributor 2 transports the material to the feeding component 4, and at the same time drives the feeding component 4 to act on the soil layer, so that the fertilizer is applied deep below the soil surface.

[0069] Among them, the material distribution mechanism refers to the existing technology, and is not limited to the specific types and categories of the material distribution mechanism in this embodiment, so it will not be described in detail.

[0070] Specifically, such as Figure 3 As shown, a material distribution vehicle 2 and a feeding assembly 4 are used for a wheat planting and fertilizing device. The material distribution vehicle 2 includes a material distribution bin 21 and a material guide pipe 23. The motor 22 is fixedly installed on one side of the material distribution bin 21, and the material distribution bin 21 is connected to the connecting assembly 42. The material distribution bin 21 is connected and communicated with the feeding cylinder 41 through the material guide pipe 23.

[0071] It should be noted that the present invention is a wheat planting and fertilizing device. Through the arrangement of the material dividing vehicle 2 and the feeding assembly 4, in the process of deep application of fertilizer, the motor 22 drives the connecting assembly 42 for transmission, so that the connecting assembly 42 drives the feeding barrel 41 to perform reciprocating motion similar to a piston. During the reciprocating motion, the feeding barrel 41 will drive the fertilizer to move to the soil layer after the trenching by the trenching disc 3.

[0072] Furthermore, Figures 4-8 As shown, a feeding assembly 4 for a wheat planting and fertilizing device includes a feeding cylinder 41 and a connecting assembly 42, a slide 413, and a sweeping cylinder 411, which are slidably connected via pulleys installed on the side walls; a material box 412 and the connecting sides of the slide 413 are rotationally connected via embedded steel balls; when the material box 412 passes through the third guide groove 416, the slide 413 rotates 90°; when the material box 412 passes through the fourth guide groove 417, the slide 413 also rotates 90°;

[0073] One end of the connecting rod 422 is eccentrically connected to the outer side of the driving disk 421; the connecting rod 422 is as shown in FIG. Figure 4 The bent shape shown here can fit the material distribution vehicle 2 to the greatest extent possible, thereby reducing the floor space.

[0074] As a preferred embodiment, the guide protrusion 4121 on the material box 412 can be a pulley to minimize the contact friction with the sweeping barrel 411.

[0075] It should be noted that the present invention is a wheat planting and fertilizing device. Through the provision of a feeding cylinder 41 and a connecting assembly 42, during the process of fertilizing wheat, the motor 22 drives the driving disc 421 connected thereto to rotate, and the driving disc 421 drives the connecting rod 422 to move during the rotation process, and the connecting rod 422 then drives the sliding seat 413 connected thereto to slide relative to the sweeping cylinder 411;

[0076] The sliding seat 413 is divided into three states based on the sliding process of the sweeping drum 411:

[0077] The material box 412 slides based on the second guide groove 415, with the opening facing upwards, to receive the fertilizer delivered by the sub-bin 21;

[0078] When feeding, the material box 412 is flipped based on the guide groove 416, with the opening facing up and down, and a relatively closed space is formed based on the slide 413;

[0079] During the discharge, the material box 412 is turned over based on the guide groove 417, with the opening facing downward, and the fertilizer is discharged by its own gravity.

[0080] In the above process, the material box 412 is guided and moved based on the guide groove 2 415, the guide groove 3 416, and the guide groove 4 417 by the guide protrusion 1 4121 attached thereto, and the slide 413 is guided and moved based on the slide 413 by the guide protrusion 2 4131 attached thereto. Therefore, when the material box 412 undergoes a structural state transformation based on the guide groove 2 415, the guide groove 3 416, and the guide groove 4 417 by the guide protrusion 1 4121 attached thereto, it rotates relative to the slide 413.

[0081] It is worth mentioning that the feeding drum 41 is connected to the material distribution vehicle 2 through the connecting assembly 42 and is synchronously driven by the motor 22. When the motor 22 is started and the material distribution bin 21 is performing material distribution, the slide 413 located inside the sweeping drum 411 drives the material box 412 to move, and the material box 412 is turned over under the guidance of the sweeping drum 411 to realize material receiving, feeding and discharging. The material box 412 carries an appropriate amount of fertilizer, and the movement of the slide 413 enables the material box 412 to deliver the fertilizer to the soil surface after the trench is opened, so that the material spreading distance is closer and more concentrated.

[0082] In addition, during the fertilization process, when the opening of the material box 412 is downward, a relatively closed environment is formed between the sweeping barrel 411 and the material distribution bin 21, which can effectively prevent excessive external moisture from flowing into the interior of the material distribution bin 21 and causing fertilizer denaturation and nutrient volatilization and loss, thereby ensuring the integrity of fertilizer storage during the fertilization process to a certain extent.

[0083] As a preferred embodiment, the sweeping barrel 411 is provided with a guide groove 1 414, and the slide 413 is provided with a guide protrusion 2 4131, which passes through the inside of the sweeping barrel 411 based on the guide groove 1 414 to its outside and connects with the connecting component 42, thereby avoiding transmission inside the sweeping barrel 411 and minimizing the space occupied by the feeding barrel 41; the guide protrusion 2 4131 is fixedly connected or rotatably connected to the slide 413; the guide protrusion 2 4131 is rotatably connected to the connecting component 42, and the guide protrusion 2 4131 can be replaced by a bearing.

[0084] The material box 412 and the slide 413 are detachably connected, so that the material box 412 can be replaced according to the amount of fertilizer to be applied, and the amount of fertilizer to be applied can be secondary controlled in combination with the sub-bin 21 .

[0085] [Example 2]

[0086] Based on the above embodiment 1, in accordance with the notice of Shandong Provincial Agricultural Technology Extension Center "Lu Nong Ji Tu Fei Zi

[2022] No. 11: "Notice on Printing and Issuing the Guidance on Scientific Fertilization Technology for the Whole Growth Period of Wheat in 2022-2023", which advocates "... deep application of chemical fertilizers, deep application of fertilizers below the side of the seeds, controlling the distance between seeds and fertilizers to 10 cm to 15 cm, and the fertilization depth to greater than 10 cm...", in order to achieve further deep application of fertilizers while ensuring dry and concentrated fertilization, this embodiment is proposed:

[0087] Specific, and Figures 3-5 As shown, a feeding assembly 4 for a wheat planting and fertilizing device, a deep application assembly 43 is provided at the bottom end of a feeding cylinder 41: when the deep application assembly 43 is subjected to force on a slide 413, it slides relative to the sweeping cylinder 411; when the deep application assembly 43 slides to the top and is released from restriction, it rotates relative to the sweeping cylinder 411.

[0088] Further, such as Figures 9 and 10 As shown, the deep application component 43 of the feeding component 4 of a wheat planting and fertilizing device, the shovel 431 and the sweeping cylinder 411 slide relative to each other and can rotate.

[0089] It should be noted that the present invention is a wheat planting fertilization device. Through the deep fertilization component 43, during the wheat fertilization process, the slide 413 slides back and forth based on the sweeping cylinder 411. When the slide 413 slides to the bottom end of the sweeping cylinder 411 and contacts the shovel 431, the slide 413 continues to slide toward the shovel 431, applying force to the two shovels 431.

[0090] The initial state of the two shovels 431 is as follows Figure 10 As shown, they fit together. After the two shovels 431 are subjected to force on the sliding seat 413, they slide relatively based on the sweeping cylinder 411 and act on the soil surface to penetrate into the soil. Then the shovel 431 continues to penetrate. After the two shovels 431 slide into place based on the sweeping cylinder 411, the shovel 431 is continuously subjected to force and rotates relatively under the soil surface based on the sweeping cylinder 411, and is in a relatively open state. At the same time, the state of the material box 412 located above it is open downward, and the fertilizer inside the material box 412 falls into the soil, thereby realizing deep application of the fertilizer.

[0091] Among them, one end of the spring 432 is fixedly connected to the sweeping cylinder 411, and the other end is fixedly connected to the slider 4311; the sweeping cylinder 411 is provided with a slide groove 4111 that matches the structure of the slider 4311, and the slider 4311 slides relatively based on the slide groove 4111; a bearing is provided between the shovel 431 and the slider 4311, and a rotation connection is achieved through the bearing; the limiter 433 is a limit rod, such as Figure 9 As shown, when the slider 4311 moves to the point where the limiting member 433 is out of contact with the sweeping tube 411 , the shovel 431 can rotate.

[0092] Among them, those skilled in the art will understand that, in order to make the shovel 431 bear the force better, as Figure 10 In the structural state shown, the connecting arm is curved, and the shovel 431 is preferentially used to bear the pressure from the slide 413;

[0093] In addition, the guide groove four 417 can be opened at a position relatively close to the deep application component 43. When the material box 412 is flipped based on the guide groove four 417, as an ideal operating state, the two shovels 431 are opened relative to each other at the same time, so that the fertilizer carried by the material box 412 can fall directly into the soil, avoiding unnecessary waste by sticking to the soil adhering to the deep application component 43.

[0094] As a preferred embodiment, one end of the slide 413 adjacent to the shovel 431 is provided with a force rod 4133 for extending into the shovel 431 to apply force: when the force rod 4133 extends into the inner side of the shovel 431, the inclined surface of the shovel 431 is subjected to the force from the force rod 4133 based on the vertical direction of the sweeping barrel 411; the force rod 4133 is fixedly connected to the bottom end of the slide 413; the end of the force rod 4133 adjacent to the shovel 431 is a spherical surface, which can ensure that the force applied to the shovel 431 is sufficiently smooth, and can also be replaced by a pulley.

[0095] It is worth mentioning that the fertilizer is transported through the feeding barrel 41, and the shovel 431 acts on the soil to further open holes. On the one hand, the fertilizer can be applied to a depth closer to the wheat root system, and on the other hand, the slide 413 and the material box 412 are separated from excessive contact with the soil surface to ensure dryness during the fertilization process.

[0096] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the invention as claimed.
