Description

TECHNICAL FIELD

[0001] The utility model relates to the field of agricultural machinery, and more particularly to a fertilizer spreading equipment for agricultural application. BACKGROUND

[0002] With the development of modern agriculture, fertilization, as one of the important links of agricultural production, plays an important role in crop growth and yield improvement. Currently, fertilizer spreading operation mainly relies on manual spreading, large-scale fertilizer spreader matched with tractors or semi-mechanized equipment. However, in small and medium-sized farmland, hilly areas and complex terrain areas, the traditional fertilization method and existing equipment still have many limitations.

[0003] Firstly, although manual spreading of fertilizer has low cost, it has low efficiency, high labor intensity and uneven fertilization, which can easily cause fertilizer waste or uneven distribution of soil fertility, affecting the consistency of crop growth.

[0004] Secondly, the existing mechanized fertilizer spreading equipment is mostly large agricultural machinery, which has complex structure and high cost, and is difficult to meet the use requirements of small-scale farmland and complex terrain areas. At the same time, such equipment usually needs to be equipped with power machinery for traction or driving, which not only has high operation threshold, but also has poor flexibility when turning and reversing in the field, limiting its application range.

[0005] In addition, some semi-mechanized fertilization devices have obvious defects in fertilizer quantitative control, discharge uniformity and anti-blocking performance, although they are small in size. For example, some devices use simple gravity feeding method, lack effective quantitative adjustment structure, which makes it difficult to control the amount of fertilization; for example, the rotary dial structure does not set a scraper cleaning device, which is easy to cause fertilizer residue to block, affecting the stability of continuous operation.

[0006] In addition, the existing equipment often ignores the operation convenience and adjustability in the structure design, for example, the push handle angle is fixed, the direction adjustment is inconvenient, the discharge port cannot be flexibly adjusted according to the fertilization demand, which further reduces the practicability and adaptability.

[0007] In summary, the existing technology still has many shortcomings in miniaturization, portability, quantitative control, anti-blocking performance and operation convenience, and a new type of fertilizer spreading equipment with reasonable structure, simple operation and suitable for various farmland environments is needed to make up for the above defects. Therefore, we make improvements on it and propose a fertilizer spreading equipment for agricultural application. CONTENT OF THE UTILITY MODEL

[0033] The rotary dial 7 is rotatably installed on the support chassis 1 through a bearing seat 10 and is located below the material guiding inclined plate 6.

[0034] A material falling hole plate 11 is fixedly installed on the rotary dial 7 and rotates synchronously with the rotary dial 7.

[0035] A scraper 12 is fixed on the support chassis 1 through a scraper adjusting bolt 13 and is located at one side of the rotary dial 7 and in contact with the surface of the rotary dial 7.

[0036] A crank 9 is connected with a chain wheel 15 through a crank driving shaft 8, and the chain wheel 15 is drivingly connected with the rotary dial 7 through a transmission chain 14.

[0037] A discharge port adjusting handle 4 is connected with a discharge port adjusting plate 5, the discharge port adjusting plate 5 is arranged below the rotary dial 7 and is connected with a fertilizer outlet guide pipe 16, and the fertilizer outlet guide pipe 16 is fixed on the support chassis 1.

[0038] Working principle: The device is a pure mechanical fertilizer spreading device, and the quantitative material falling and uniform spreading of the fertilizer are completed by human power pushing and driving.

[0039] In use, an operator holds the push handrail 2 to push the device forward, and a mobile roller 17 installed below the support chassis 1 rolls to drive the device to move along the field. At the same time, the direction of the roller can be adjusted by pulling a direction adjusting pull rod 18 to realize flexible turning.

[0040] The fertilizer is stored in the fertilizer storage tank 3 located at the upper part of the device, and the fertilizer slides along the guide chute 6 under the action of gravity to the area below the rotating disc 7. The rotating disc 7 is installed on the support chassis 1 through the bearing seat 10, and a plurality of material falling hole plates 11 are provided on the periphery of the rotating disc 7, forming a plurality of quantitative material falling hole positions.

[0041] The operator rotates the handle part, the crank 9 rotates and drives the sprocket 15 to rotate through the crank drive shaft 8, and the power is transmitted to the rotating disc 7 through the transmission chain 14 to make it rotate synchronously. As the disc rotates, the fertilizer is brought into the material falling hole and falls after rotating with the disc to the position below.

[0042] In order to prevent the influence of fertilizer residue on the stability of the discharge, the scraper 12 is tightly attached to the surface of the rotating disc, and the gap between the scraper and the disc is adjusted by the scraper adjusting bolt 13 to ensure the cleaning effect.

[0043] The falling fertilizer controls the flow rate through the discharge port adjusting plate 5, which is adjusted in opening by the discharge port adjusting handle 4, and finally guided to the ground through the fertilizer outlet guide pipe 16 fixed on the support chassis 1 to complete the spreading operation.

[0044] Working process: when using the fertilizer spreading device to carry out field fertilization operation, first, the granular fertilizer required for spreading is loaded into the fertilizer storage tank 3 located at the upper part of the device. Then, according to the required fertilization amount, the operator adjusts the opening size of the material falling channel by adjusting the discharge port adjusting handle 4 to drive the discharge port adjusting plate 5 to move.

[0045] The operator holds the push handrail 2 installed at the rear end of the support chassis 1 and pushes the device forward. The bottom of the device is provided with moving rollers 17 for carrying the weight of the whole machine and realizing smooth movement. When turning, the operator pulls or adjusts the direction adjusting pull rod 18 to change the direction of the rollers, so that the device can turn flexibly.

[0046] During the forward movement of the device, the fertilizer slides along the guide chute 6 fixed on the support chassis 1 under the action of gravity to the surface of the rotating disc 7 below. The disc is installed on the chassis through the bearing seat 10 and can rotate freely. The periphery of the disc is provided with a plurality of material falling hole plates 11, forming a quantitative material falling structure.

[0047] At the same time, the operator rotates the crank part, i.e. the crank 9, which rotates the crank drive shaft 8 connected thereto, further driving the sprocket 15 installed thereon to operate. The power is transmitted to the rotating disc 7 through the transmission chain 14 to make it rotate synchronously.

[0048] With the rotation of the rotary dial 7, the fertilizer is introduced into each drop hole, and is rotated to the lower position after the dial. In order to prevent the fertilizer from adhering to the dial surface to cause blockage or leakage, a scraper 12 is provided on one side of the dial, and the fit gap between the scraper and the dial is adjusted by a scraper adjusting bolt 13 to ensure the cleanliness of the dial surface.

[0049] The falling fertilizer enters the fertilizer outlet guide pipe 16 fixed on the support chassis 1 after the flow is controlled by the discharge port adjusting plate 5, and is finally guided to the ground to complete uniform spreading.
