Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a fertilizer applicator for a seeder and a wheat seeder containing the same. Background Technology

[0002] The structure and application method of fertilizing seeders vary depending on the specific model, but generally revolve around key aspects such as fertilizer storage, transportation, and control of fertilizer application rate and depth. The structure of a fertilizing seeder mainly includes a frame, on which a fertilizer tank and a furrow opener are mounted. A fertilizer discharge device is located at the bottom of the fertilizer tank, and a fertilizer delivery pipe is located at the outlet of the discharge device. The lower end of the delivery pipe connects to the furrow opener. The fertilization process is as follows: fertilizer in the fertilizer tank is discharged through the discharge device to the delivery pipe, and then falls along the pipe to the furrow opener. The furrow opener creates furrows in the soil, sowing the fertilizer and seeds into the soil.

[0003] The fertilizer applicator, as a key component for controlling fertilizer application, requires an external drive to operate. Currently, some seeders use a single-input shaft chain drive to drive both the seeding and fertilizer application shafts. This means the power from the external drive is first transmitted to an intermediate shaft via a chain drive, and each fertilizer applicator or seeder then receives power from this intermediate shaft via a chain drive or gear drive mechanism. This structure requires at least the number of chain drive or gear drive mechanisms for the fertilizer applicators, increasing the overall size and weight of the seeder. Furthermore, the complex transmission structure not only increases manufacturing and maintenance costs but also hinders lightweight design, which is detrimental to improving operational efficiency and reducing energy consumption.

[0004] Furthermore, currently, wheat sowing is mainly carried out using seeders, which generally employ an equal row spacing pattern according to demand. However, existing fertilization devices installed on seeders suffer from inaccurate fertilization, resulting in varying amounts of fertilizer applied between different rows. This leads to uneven fertilization of wheat in different rows during later growth, making it difficult to achieve stable and high yields. Therefore, there is an urgent need for a fertilization device for seeders that can improve the accuracy of fertilization. Summary of the Invention

[0005] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a fertilization device for a seeder that is conducive to improving the accuracy of fertilization. In addition, a wheat seeder is also provided.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] According to one aspect of this application, a fertilization device for a seeder is provided, comprising:

[0008] frame;

[0009] The rotating shaft is horizontally mounted on the frame.

[0010] A fertilizer scraping device is provided in multiple configurations. Each fertilizer scraping device includes a cover and a scraping mechanism. The cover is fixedly installed relative to the frame. The cover has a fertilizer discharge channel for discharging fertilizer. The upper end of the fertilizer discharge channel is open to form a fertilizer inlet for putting fertilizer in, and the lower end of the fertilizer discharge channel is open to form a fertilizer outlet. The rotating shaft passes horizontally through the cover. The scraping mechanism is installed on the rotating shaft, and at least a portion of the scraping mechanism extends into the fertilizer discharge channel.

[0011] A rotation drive mechanism is installed on the frame. One end of the rotation shaft is connected to the rotation drive mechanism, and the rotation shaft can rotate relative to the frame under the drive of the rotation drive mechanism. When the rotation shaft rotates, it can drive the scraping mechanism to rotate, so that the fertilizer located in the fertilizer discharge channel and in contact with the scraping mechanism is scraped off and discharged towards the fertilizer discharge outlet.

[0012] The beneficial effects of this utility model are as follows: In this embodiment, a rotating shaft and a rotating drive mechanism are installed on the frame, and the rotating shaft and the rotating drive mechanism are connected. A scraping mechanism is installed on the rotating shaft. When the rotating drive mechanism drives the rotating shaft to rotate, the scraping mechanism rotates accordingly. At this time, the part of the scraping mechanism that extends into the fertilizer discharge channel can scrape off the fertilizer located at the upper end of the fertilizer discharge channel when it rotates. The scraped fertilizer can be transported out of the fertilizer discharge outlet through the fertilizer discharge channel, which is beneficial for precise fertilization according to the fertilizer application requirements and for improving the uniformity of fertilization. In addition, by setting multiple fertilizer scraping devices on a rotating shaft, the rotating shaft is driven to rotate by the rotating drive mechanism alone. When the rotating shaft rotates, it can drive all the scraping mechanisms to rotate and scrape off the fertilizer in the fertilizer discharge channel that is in contact with the scraping mechanism and discharge it towards the fertilizer discharge outlet. This simplifies the fertilization mechanism, thereby reducing the overall size and weight of the seeder and achieving a lightweight design of the seeder. Furthermore, during fertilization, multiple rows of wheat seedlings can be fertilized simultaneously, which is beneficial for improving fertilization efficiency. Therefore, installing the fertilization device in this embodiment on the seeder is beneficial for achieving a lightweight design of the seeder, and also allows for precise fertilization during the actual sowing process, which helps to improve the uniformity of fertilization.

[0013] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0014] According to one embodiment of the present invention, the fertilization device for a seeder further includes:

[0015] A fertilizer storage box is installed on the frame and located above the rotating shaft. The fertilizer storage box is provided with a fertilizer storage cavity for storing fertilizer. Multiple fertilizer drop ports that communicate with the fertilizer storage cavity are spaced apart along the length of the fertilizer storage box at the bottom.

[0016] Multiple fertilizer scraping devices are positioned directly opposite multiple fertilizer discharge ports. Each cover is installed at the bottom of the fertilizer storage box, directly opposite a fertilizer discharge port. The fertilizer inlet is connected to the fertilizer discharge port.

[0017] In this embodiment, a fertilizer storage box is installed on the frame. The fertilizer storage box has a fertilizer storage cavity for storing fertilizer. Before the fertilization work begins, the required fertilizer is stored in the fertilizer storage cavity. During fertilization, there is no need to frequently add fertilizer to the fertilization device, which helps to improve the efficiency of fertilization work. Through the multiple fertilizer drop ports on the lower side of the fertilizer storage box and the multiple fertilizer scraping devices, the fertilizer stored in the fertilizer storage cavity can fall into the fertilizer discharge channel through the fertilizer drop ports. By scraping the fertilizer stored in the fertilizer storage cavity downwards by the fertilizer scraping devices, it is easy to accurately control the amount of fertilizer scraped down by each fertilizer scraping device.

[0018] According to one embodiment of the present invention, the scraping mechanism includes:

[0019] A fertilizer scraping cylinder is sleeved on the rotating shaft and can rotate with the rotating shaft. At least a portion of the fertilizer scraping cylinder extends into the fertilizer discharge channel. The outer side of the fertilizer scraping cylinder is circumferentially provided with fertilizer scraping parts for scraping fertilizer located in the fertilizer discharge channel and in contact with the scraping mechanism toward the fertilizer discharge outlet.

[0020] In this embodiment, a fertilizer scraping part is provided on the outside of the fertilizer scraping cylinder. When the fertilizer scraping cylinder rotates with the rotating shaft, the fertilizer scraping part also rotates. When the fertilizer scraping part rotates, it can scrape the fertilizer located above the fertilizer discharge channel downward in time, avoiding the accumulation of fertilizer in the fertilizer discharge channel, which is conducive to precise fertilization.

[0021] According to one embodiment of the present invention, the fertilizer scraping part includes a plurality of fertilizer scraping protrusions and a plurality of fertilizer filling grooves, wherein the plurality of fertilizer scraping protrusions and the plurality of fertilizer filling grooves are arranged alternately.

[0022] In this embodiment, multiple fertilizer scraping protrusions and multiple fertilizer filling troughs are arranged alternately. When the fertilizer scraping part rotates with the rotating shaft, the fertilizer scraping protrusions scrape the fertilizer located above the fertilizer discharge channel. The fertilizer falls into the fertilizer filling trough. The opening of the fertilizer filling trough also rotates towards the lower side of the fertilizer scraping part when the fertilizer scraping part rotates, which can discharge the fertilizer in the fertilizer filling trough downwards, which is conducive to accurately delivering fertilizer outwards, thereby facilitating precise fertilization.

[0023] According to one embodiment of the present invention, the fertilizer scraping cylinder is further provided with a top-stop extension cylinder, the rotating shaft passes through the top-stop extension cylinder, and the top-stop extension cylinder extends out of the cover;

[0024] The scraping mechanism further includes:

[0025] A fertilizer lateral blocking cylinder is installed on the cover body, directly opposite the fertilizer scraping cylinder body, and the fertilizer lateral blocking cylinder is sleeved on the outer periphery of the top extension cylinder;

[0026] Multiple locking components are provided, and the fertilizer scraping cylinder and the top extension cylinder are respectively locked to the rotating shaft through a number of locking components.

[0027] In this embodiment, a top-stop extension cylinder is provided on the fertilizer scraping cylinder body. The fertilizer scraping cylinder body and the top-stop extension cylinder are respectively locked to the rotating shaft by several locking parts, which facilitates the locking and fixing of the fertilizer scraping cylinder body and prevents the fertilizer scraping cylinder body from being displaced along the length direction of the rotating shaft. In addition, by providing a fertilizer side-blocking cylinder on the cover body, it is beneficial to block the fertilizer from the opening on the side of the top-stop extension cylinder that extends out of the cover body, and prevent the fertilizer located in the fertilizer discharge channel from overflowing out of the opening on the side of the top-stop extension cylinder that extends out of the cover body.

[0028] According to one embodiment of the present invention, the length of the fertilizer scraping cylinder extending into the fertilizer discharge channel is adjustable.

[0029] In this embodiment, the length of the fertilizer scraping cylinder extending into the fertilizer discharge channel is adjustable. This allows for adjustment of the length of the fertilizer scraping cylinder into the fertilizer discharge channel according to the fertilizer application requirements. This facilitates precise adjustment of the fertilizer application amount based on the application needs, meets different fertilizer application requirements, and improves the applicability of the fertilizer application device used in seeders.

[0030] According to one embodiment of the present utility model, the cover is provided with a first lateral opening, the first lateral opening is connected to the fertilizer discharge channel, and the fertilizer scraping cylinder extends into the fertilizer discharge channel from the first lateral opening;

[0031] The scraping mechanism further includes:

[0032] A fertilizer lateral blocking ring is installed on the cover body, directly opposite the first lateral opening, and the fertilizer lateral blocking ring is sleeved on the outside of the fertilizer scraping cylinder. The outer wall of the fertilizer scraping cylinder abuts against the fertilizer lateral blocking ring. The fertilizer lateral blocking ring and the fertilizer scraping cylinder block the first lateral opening. The fertilizer lateral blocking ring can rotate relative to the cover body as the fertilizer scraping cylinder rotates.

[0033] In this embodiment, a fertilizer lateral blocking ring is installed on the cover directly opposite the first lateral opening. The outer periphery of the fertilizer scraping cylinder abuts against the fertilizer lateral blocking ring, and the fertilizer lateral blocking ring can rotate relative to the cover as the fertilizer scraping cylinder rotates. The fertilizer lateral blocking ring and the fertilizer scraping cylinder block the first lateral opening, preventing fertilizer in the fertilizer discharge channel from overflowing outward through the first lateral opening.

[0034] According to one embodiment of the present invention, the fertilization device for a seeder further includes:

[0035] An axial adjustment mechanism is installed on the frame. The rotating shaft is movably connected to the axial adjustment mechanism, and the rotating shaft can adjust its installation position relative to the frame under the drive of the axial adjustment mechanism, thereby adjusting the length of the scraping mechanism extending into the fertilizer discharge channel.

[0036] In this embodiment, an axial adjustment mechanism is installed on the frame. The axial adjustment mechanism can adjust the installation position of the rotating shaft relative to the frame, thereby simultaneously adjusting the length of all scraping mechanisms on the rotating shaft extending into the fertilizer discharge channel. This facilitates the adjustment of the length of the scraping mechanism extending into the fertilizer discharge channel, thereby adjusting the amount of fertilizer scraped when the scraping mechanism rotates. This allows for flexible adjustment of the fertilizer application amount according to the actual fertilizer application requirements during fertilization.

[0037] According to one embodiment of the present invention, the rotation drive mechanism includes:

[0038] Rolling wheels are rotatably mounted on the frame via a rotating connecting shaft;

[0039] A driven mechanism is mounted on the frame;

[0040] A transmission mechanism is connected between the driven mechanism and the rolling wheel, and the driven mechanism can drive the rotating shaft to rotate under the drive of the rolling wheel.

[0041] In this embodiment, a transmission mechanism is used to connect the driven mechanism and the rolling wheel. When the fertilizer applicator is installed on the seeder and moved under the drive of an external force, the rolling wheel rolls and drives the driven mechanism to drive the rotating shaft to rotate. At this time, the rotation speed of the rotating shaft is determined by the rolling speed of the rolling wheel. This is beneficial to control the rotation speed of the scraping mechanism on the rotating shaft by controlling the speed of the rolling wheel, thereby controlling the amount of fertilizer scraped by the scraping mechanism.

[0042] According to one embodiment of the present invention, the fertilization device for a seeder further includes:

[0043] Multiple fertilizer boots are provided, each corresponding to one of the fertilizer scraping devices. The multiple fertilizer boots are installed at intervals along the length of the rotating shaft on the frame and located below the fertilizer scraping devices. Each fertilizer boot forms a fertilizer falling channel. The upper end of the fertilizer falling channel is open to form a fertilizer input port, and the lower end of the fertilizer falling channel is open to form a fertilizer output port.

[0044] Multiple fertilizer transfer pipes are provided, each corresponding to one of the fertilizer scraping devices. The upper end of the fertilizer transfer pipe is connected to the fertilizer outlet, and the lower end of the fertilizer transfer pipe is connected to the upper end of the fertilizer application boot.

[0045] In this embodiment, the upper end of the fertilizer transfer pipe is connected to the fertilizer outlet, and the lower end of the fertilizer transfer pipe is connected to the upper end of the fertilizer application boot. The fertilizer is transferred from the fertilizer scraping device to the fertilizer application boot through the fertilizer transfer pipe, which facilitates the input of fertilizer into the soil through the fertilizer application boot and makes it easy to input fertilizer into the accurate position.

[0046] According to one embodiment of the present invention, every two fertilizer boots constitute a fertilizer boot group, and the distance between the two fertilizer boots in the same fertilizer boot group is L, where L ranges from 22cm to 26cm.

[0047] In this embodiment, the spacing between two fertilizer boots in the same group of fertilizer boots is in the range of 22cm-26cm. The spacing between the two fertilizer boots in the same group of fertilizer boots is suitable. When the seeder is used to sow in a narrow row planting mode and the seeder plants four rows of wheat as a group, it is beneficial to place one fertilizer boot in the middle of the first and second rows of wheat, and the other fertilizer boot in the middle of the third and fourth rows of wheat. This is conducive to achieving uniform pre-fertilization of the four rows of wheat, ensuring uniform fertilization after the four rows of wheat grow, and achieving balanced growth of the four rows of wheat, thereby improving wheat yield.

[0048] According to another aspect of this application, a wheat seeder is provided, comprising:

[0049] Traction device;

[0050] The aforementioned fertilization device for a seeder has its frame connected to the traction device.

[0051] The wheat seeder in this embodiment includes the aforementioned fertilization device for the seeder. When the rotary drive mechanism drives the rotating shaft to rotate, the scraping mechanism rotates accordingly. At this time, a portion of the scraping mechanism extending into the fertilizer discharge channel can scrape off the fertilizer located at the upper end of the fertilizer discharge channel during rotation. The scraped-off fertilizer can be transported out of the fertilizer discharge outlet through the fertilizer discharge channel, which is beneficial for precise fertilization according to the fertilizer application requirements and for improving the uniformity of fertilization. In addition, by setting multiple fertilizer scraping devices on a rotating shaft, the rotary drive mechanism alone drives the rotating shaft to rotate. When the rotating shaft rotates, it can drive all the scraping mechanisms to rotate and scrape off the fertilizer in the fertilizer discharge channel that is in contact with the scraping mechanisms and discharge it towards the fertilizer discharge outlet. This simplifies the fertilization mechanism, thereby reducing the overall size and weight of the seeder and achieving a lightweight design. Furthermore, during fertilization, multiple rows of wheat seedlings can be fertilized simultaneously, which is beneficial for improving fertilization efficiency. Attached Figure Description

When the rotary shaft 4 rotates, it can drive the scraping mechanism to rotate, so that the fertilizer located in the fertilizer discharge channel and in contact with the scraping mechanism is scraped off and discharged towards the fertilizer discharge outlet.

[0067] In this embodiment, as Figures 1 to 3As shown, in this embodiment, a rotating shaft 4 and a rotating drive mechanism are installed on the frame 1, and the rotating shaft 4 and the rotating drive mechanism are connected. A scraping mechanism is installed on the rotating shaft 4. When the rotating drive mechanism drives the rotating shaft 4 to rotate, the scraping mechanism rotates accordingly. At this time, the part of the scraping mechanism that extends into the fertilizer discharge channel can scrape off the fertilizer located at the upper end of the fertilizer discharge channel when it rotates. The scraped fertilizer can be transported out of the fertilizer discharge outlet through the fertilizer discharge channel, which is beneficial for precise fertilization according to the fertilizer application requirements and for improving the uniformity of fertilization. In addition, by setting multiple fertilizer scraping devices 3 on a rotating shaft 4, the rotating shaft 4 is driven to rotate by the rotating drive mechanism alone. When the rotating shaft 4 rotates, it can drive all the scraping mechanisms to rotate and scrape off the fertilizer in the fertilizer discharge channel that is in contact with the scraping mechanism and discharge it towards the fertilizer discharge outlet. This simplifies the fertilization mechanism, thereby reducing the overall size and weight of the seeder and realizing the lightweight design of the seeder. Furthermore, during the fertilization work, multiple rows of wheat seedlings can be fertilized simultaneously, which is beneficial for improving the efficiency of fertilization. Therefore, installing the fertilization device in this embodiment on the seeder is beneficial for achieving a lightweight design of the seeder, and also allows for precise fertilization during the actual sowing process, which helps to improve the uniformity of fertilization.

During fertilization, there is no need to frequently add fertilizer to the fertilization device, which helps to improve the efficiency of fertilization work. Through the multiple fertilizer drop outlets on the lower side of the fertilizer storage box 2 and the multiple fertilizer scraping devices 3 arranged one-to-one, the fertilizer stored in the fertilizer storage cavity can fall into the fertilizer discharge channel through the fertilizer drop outlets. By scraping the fertilizer stored in the fertilizer storage cavity downward by the fertilizer scraping devices 3, it is easy to accurately control the amount of fertilizer scraped down by each fertilizer scraping device 3.

[0095] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, by installing an axial adjustment mechanism 8 on the frame 1, the axial adjustment mechanism 8 can adjust the installation position of the rotating shaft 4 relative to the frame 1, thereby simultaneously adjusting the length of all scraping mechanisms on the rotating shaft 4 extending into the fertilizer discharge channel. This facilitates adjusting the length of the scraping mechanisms extending into the fertilizer discharge channel, thereby adjusting the amount of fertilizer scraped when the scraping mechanism rotates. This is beneficial for flexibly adjusting the amount of fertilizer applied according to the actual fertilizer application requirements during fertilization.

[0096] Furthermore, such as Figures 1 to 3As shown, the axial adjustment mechanism 8 is installed on the vertical support beam 16. The rotating shaft 4 is movably connected to the axial adjustment mechanism 8, and the rotating shaft 4 can be moved to the left or right under the action of the axial adjustment mechanism 8 to adjust the length of the scraping mechanism extending into the fertilizer discharge channel. In addition, the structure of the axial adjustment mechanism 8 is not illustrated in this embodiment. The structure and working principle of the axial adjustment mechanism 8 can be referred to the prior art in this field, and will not be described in detail here.

[0097] One embodiment of this utility model is as follows: Figures 1 to 3 As shown, the rotation drive mechanism includes:

[0098] Roller 14 is rotatably mounted on frame 1 via rotating connecting shaft 17;

[0099] The driven mechanism is mounted on the rotating shaft 4;

[0100] The transmission mechanism is connected between the driven mechanism and the rolling wheel 14. The driven mechanism can drive the rotating shaft 4 to rotate under the drive of the rolling wheel 14.

[0101] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, the driven mechanism and the rolling wheel 14 are connected by a transmission mechanism. When the fertilizer application device in this embodiment is installed on the seeder and moved under the drive of an external force, the rolling wheel 14 rolls and drives the driven mechanism to drive the rotating shaft 4 to rotate. At this time, the rotation speed of the rotating shaft 4 is determined by the rolling speed of the rolling wheel 14. This is beneficial to control the rotation speed of the scraping mechanism on the rotating shaft 4 by controlling the speed of the rolling wheel 14, thereby controlling the amount of fertilizer scraped by the scraping mechanism.

[0102] Furthermore, such as Figures 1 to 3 As shown, the transmission mechanism in this embodiment is protected by a transmission mechanism protective cover 9. The transmission mechanism used in this embodiment is a chain, which is connected between the driven mechanism and the rolling wheel 14. A sprocket 1 is provided on the rotating connecting shaft 17, and a sprocket 2 is fixedly installed on the rotating connecting shaft 17. Furthermore, this embodiment also provides a reversing sprocket, which is fixedly installed on the frame 1 and installed between sprocket 1 and sprocket 2. Sprocket 1, sprocket 2 and the reversing sprocket are arranged in parallel. Chain 1 is wound between the reversing sprocket and chain 2 is wound between the reversing sprocket and sprocket 2. Furthermore, sprocket 1, sprocket 2 and the reversing sprocket are not illustrated in this embodiment. In addition, the structure of the transmission mechanism can also refer to other existing technologies, which will not be described in detail here.

[0103] One embodiment of this utility model is as follows: Figures 1 to 3 As shown, the fertilization device for the seeder also includes:

[0104] The fertilizer boots 6 correspond one-to-one with multiple fertilizer scraping devices 3. Multiple fertilizer boots 6 are installed at intervals along the length of the rotating shaft 4 on the frame 1 and located below the fertilizer scraping devices 3. Each fertilizer boot 6 forms a fertilizer falling channel. The upper end of the fertilizer falling channel is open to form a fertilizer input port, and the lower end of the fertilizer falling channel is open to form a fertilizer output port.

[0105] The fertilizer transmission pipe 5 is provided with multiple fertilizer scraping devices 3, one for each of them. The upper end of the fertilizer transmission pipe 5 is connected to the fertilizer outlet, and the lower end of the fertilizer transmission pipe 5 is connected to the upper end of the fertilizer application boot 6.

[0106] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, the upper end of the fertilizer transfer pipe 5 is connected to the fertilizer outlet, and the lower end of the fertilizer transfer pipe is connected to the upper end of the fertilizer boot 6. The fertilizer is transferred from the fertilizer scraping device to the fertilizer boot 6 through the fertilizer transfer pipe 5, which facilitates the input of fertilizer into the soil through the fertilizer boot 6 and makes it easier to input the fertilizer into the accurate position.

[0107] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, the mounting beam 15 at the front end of the frame 1 is a cuboid structure. The fertilizer boot 6 is fixedly mounted on the mounting beam 15 by the mounting block 62. The mounting block 62 is fixed on the mounting beam 15 by two U-shaped clamps 61. In addition, the fertilizer boot 6 in this embodiment can also be mounted on the frame 1 by other means.

[0108] Furthermore, such as Figures 1 to 3 As shown, the fertilizer boot 6 has a fertilizer tip 60 on the front side of the bottom. When fertilizing, the lower part of the fertilizer boot 6 is inserted into the soil, which makes it easier for the fertilizer tip 60 to make grooves on the soil surface when the fertilizer boot 6 moves to fertilize, which facilitates fertilization and helps to reduce resistance.

[0109] One embodiment of this utility model is as follows: Figures 1 to 3 As shown, every two fertilizer boots 6 constitute a group of fertilizer boots 6, and the distance between the two fertilizer boots 6 in the same group of fertilizer boots is L, and the range of L is 22cm-26cm.

[0110] In this embodiment, the spacing between two fertilizer boots 6 located in the same group of fertilizer boots is in the range of 22cm-26cm. The spacing between the two fertilizer boots 6 in the same group of fertilizer boots is suitable. It is beneficial to place one fertilizer boot 6 in the middle of the first and second rows of wheat and the other fertilizer boot 6 in the middle of the third and fourth rows of wheat when the seeder is used to plant in a row-short planting mode and the seeder plants four rows of wheat as a group. This is beneficial to achieve uniform fertilization of the four rows of wheat in advance, uniform fertilization after the four rows of wheat grow, and balanced growth of the four rows of wheat, which in turn helps to increase wheat yield.

[0111] Another aspect of this application provides a wheat seeder, such as... Figures 1 to 3 As shown, it includes:

[0112] Traction device;

[0113] The aforementioned fertilizer applicator for a seeder has its frame 1 connected to the traction device.

[0114] In this embodiment, as Figures 1 to 3 As shown, the wheat seeder in this embodiment includes the aforementioned fertilization device for the seeder. When the rotation drive mechanism drives the rotating shaft 4 to rotate, the scraping mechanism rotates accordingly. At this time, the part of the scraping mechanism extending into the fertilizer discharge channel can scrape off the fertilizer located at the upper end of the fertilizer discharge channel when rotating. The scraped fertilizer can be transported out of the fertilizer discharge outlet through the fertilizer discharge channel, which is beneficial for precise fertilization according to the fertilizer application requirements and for improving the uniformity of fertilization. In addition, by setting multiple fertilizer scraping devices 3 on a rotating shaft 4, the rotating shaft 4 is driven to rotate by the rotation drive mechanism alone. When the rotating shaft 4 rotates, it can drive all the scraping mechanisms to rotate and scrape off the fertilizer in the fertilizer discharge channel that is in contact with the scraping mechanisms and discharge it towards the fertilizer discharge outlet. This simplifies the fertilization mechanism, thereby reducing the overall size and weight of the seeder and achieving a lightweight design of the seeder. Furthermore, during fertilization, multiple rows of wheat seedlings can be fertilized simultaneously, which is beneficial for improving fertilization efficiency. Therefore, installing the fertilization device in this embodiment on the seeder is beneficial for achieving a lightweight design of the seeder, and also allows for precise fertilization during the actual sowing process, which helps to improve the uniformity of fertilization.

[0115] Furthermore, such as Figures 1 to 3 As shown, a frame traction block 7 is provided on the mounting beam 13 on the frame 1. The traction device is connected to the frame traction block 7 and drives the frame assembly and the device on the frame assembly to move during operation. In addition, the structure of the frame 1 in this embodiment can be of various types. Furthermore, the sowing assembly of the wheat seeder can be set on the frame 1, and the way it is installed on the frame 1 can also be of various types. The sowing assembly and traction device are not illustrated in this embodiment. The structure and working principle of the sowing assembly and traction device can be referred to the prior art, and will not be described in detail here.

[0116] Furthermore, the seeder in this embodiment is specifically a wheat seeder. The fertilizer application device for the seeder in this embodiment can also be installed on other selected crop seeding equipment. In addition, other devices or mechanisms included in the wheat seeder can also refer to existing seeders, which will not be described in detail here.
