Description

Technical Field

[0001] This utility model belongs to the field of fertilization technology, specifically relating to an adjustable nitrogen application device. Background Technology

[0002] Fertilization is a crucial step in wheat cultivation, and proper fertilization significantly impacts wheat yield. The depth of application is a key factor influencing the effectiveness of wheat fertilization. An appropriate working depth ensures fertilizer is precisely delivered to the main root zone, facilitating absorption and minimizing fertilizer volatilization losses. However, most existing wheat fertilization equipment has significant limitations in controlling application depth.

[0003] Most existing fertilization equipment has significant shortcomings in adjusting fertilization depth. The furrow openers in such equipment are usually fixed, or depth adjustment can only be achieved by replacing different sized furrow openers. This method of adjustment is cumbersome and severely impacts operational efficiency. In practical use, the inability to flexibly adjust the fertilization depth according to soil conditions and crop growth stages often results in fertilizer being applied too shallowly or too deeply: when applied too shallowly, fertilizer is easily volatilized and lost, reducing fertilizer utilization; when applied too deeply, crop roots cannot effectively absorb nutrients, also affecting fertilizer efficiency.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable nitrogen application device that can adjust the depth and amount of fertilizer application to improve fertilizer efficiency.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: An adjustable nitrogen application device includes a movable mounting frame and a hopper fixedly connected to the mounting frame. A distributing wheel is rotatably mounted on the bottom of the hopper, and a mounting ring for mounting the distributing wheel is provided at the bottom of the hopper. A discharge pipe is provided at the bottom of the mounting ring, and a trencher is connected to the discharge pipe. The trencher and the discharge pipe are connected by an adjusting ring. The trencher has a connecting pipe that slides with the discharge pipe and a trenching tip. The trenching tip is inclined downwards, and a discharge port is formed at the connection between the trenching tip and the connecting pipe. An external thread is formed on the outer wall of the discharge pipe, and an internal thread that mates with the external thread is formed on the inner wall of the adjusting ring. A limiting ring is formed at the top of the outer wall of the connecting pipe, and a limiting groove that rotatably mates with the limiting ring is formed at the lower part of the inner wall of the adjusting ring.

[0007] Furthermore, the bottom of the outer wall of the feeding pipe is formed with multiple first limiting sliders, and the inner wall of the connecting pipe is formed with multiple first limiting grooves that cooperate with the first limiting sliders. By utilizing the cooperation between the first limiting grooves and the first limiting sliders, the rotation of the trencher can be prevented when adjusting the position of the trencher.

[0008] Furthermore, the circumferential surface of the distributing wheel has multiple annularly arranged distributing grooves, and an adjusting plate is slidably disposed within each distributing groove. The distributing wheel also includes an adjusting mechanism for adjusting the depth of the adjusting plate within the distributing groove. By changing the depth of the adjusting plate within the distributing groove, the amount of fertilizer applied is adjusted. Furthermore, the adjustment mechanism includes an adjustment wheel, a control knob, and a first return spring; a mounting cavity for mounting the adjustment wheel is formed inside the distributing wheel; multiple driving blocks are formed on the circumferential surface of the adjustment wheel; each driving block has a driving inclined surface, which gradually increases in height from the circumference of the driving block towards the outer diameter; a stop post is formed at the bottom of the adjustment plate, and the bottom of the stop post slides in contact with the driving inclined surface; a sliding hole is formed at the bottom of the distributing trough for the stop post to pass through; a second return spring is also sleeved on the stop post, one end of which is fixedly connected to the bottom of the adjustment plate, and the other end is fixedly connected to the bottom of the distributing trough. By rotating the adjustment wheel, the adjustment plate can be quickly adjusted using the driving blocks.

[0009] Furthermore, one end of the adjusting wheel has a mounting shaft that passes through one side wall of the distributing wheel. The control knob is slidably sleeved on the mounting shaft. A limiting plate is also formed at the end of the mounting shaft. The first return spring is sleeved on the mounting shaft, with one end abutting against the limiting plate and the other end abutting against the end of the control knob. Multiple second limiting grooves are formed on the mounting shaft, and multiple second limiting sliders that mate with the second limiting grooves are formed on the inner wall of the control knob. Multiple limiting protrusions are also formed on the side of the control knob near the distributing wheel, and several limiting holes that mate with the limiting protrusions are formed on the side wall of the distributing wheel. A limiting handle is also provided on the side wall of the distributing wheel. The control knob can be limited by the engagement of the limiting protrusions and the limiting holes.

[0010] Furthermore, the mounting frame is equipped with traveling wheels and auxiliary support wheels; the mounting frame also has a motor that drives the traveling wheels to rotate. A first synchronous pulley is fixedly sleeved on the output shaft of the motor, and a second synchronous pulley is fixedly sleeved on the rotating shaft of the traveling wheels. A first synchronous belt is sleeved on the first and second synchronous pulleys; a third synchronous pulley is fixedly installed at one end of the distributing wheel, and a fourth synchronous pulley is fixedly sleeved on the rotating shaft of the traveling wheel. A second synchronous belt is sleeved on the third and fourth synchronous pulleys. The motor drives the traveling wheels to rotate, and the second synchronous belt drives the distributing wheel to rotate, thereby causing the fertilizer to fall.

[0011] Furthermore, the mounting frame is also equipped with control handles. The control handles facilitate the movement of the entire device.

[0012] With the above structure, the adjustable nitrogen application device of this utility model, compared with the prior art, connects the furrow opener to the feed pipe and adjusts the height of the furrow opener by adjusting the threaded connection between the adjusting ring and the feed pipe, thereby changing the furrow depth. A discharge port is formed at the connection between the furrow tip and the connecting pipe. At the same time as furrowing, fertilizer granules can fall accurately into the furrow, accurately controlling the fertilization depth. In addition, adjustment can be made simply by rotating the adjusting ring, making operation convenient. Attached Figure Description
