Description

a fertilizer spreading device

technical field

The utility model belongs to the field of agricultural operation equipment, in particular to field fertilization technology.

Background technique

Fertilizer spreading machinery is an important field management machinery in modern agriculture. At present, the working principles of the main fertilizer spreading devices at home and abroad are basically the same. They all use the centrifugal force generated by the centrifugal disc under high-speed rotation to throw out the fertilizer falling on the centrifugal disc, and then achieve the purpose of spreading fertilizer.

After searching the US invention patent EP0402712A1, the fertilizer spreading device is designed as a double-disc structure, the number of blades is 2, the angle of the blades is adjustable, and the blade shape is bow-shaped, but this patent is only suitable for long-distance spreading of fertilizers on field crops. It is limited by the number of leaves and leaf shape, and in the process of spreading fertilizer on crops with narrow row spacing, there will be serious uneven fertilizer spreading. The small fertilizing device designed by Japanese patent JP2001320924A has 4 blades, the blades are fixed, and the leaf shape is rectangular. Although it can meet the needs of short-distance fertilization, because the blades are fixed, it cannot be flexibly adjusted according to the actual fertilization distance requirements. Adjust the width of fertilizer spreading, and its equipment is heavy, expensive, and consumes a lot of energy. Chinese utility model patent CN203467195U also adopts a single-disk design, with 6 blades and a fixed centering structure, which cannot flexibly adjust the width of fertilizer spreading according to actual needs, so that it cannot save energy and increase fertilizer spread uniformity requirements.

The existing fertilizer spreading device adopts the fixed-to-center technology or structure of the blades, so that the offset angle of the blades cannot be adjusted, and the existing feeding opening adopts a straight-through structure, and the feeding speed is too fast and the feeding is uneven, which is easy to cause The rotation of the centrifugal disc is unstable and the fertilizer accumulates in the center of the centrifugal disc and cannot be completely scattered, resulting in problems such as uneven fertilization, inability to flexibly adjust the fertilization distance, low operating efficiency, serious energy consumption, and high fertilization costs.

The outer edge of the feeding opening (4) is located above the outer contour of the flange (3-1).

The number of the blades (3-3) is preferably 8.

The shape of the feeding opening (4) is hoof-like.

The width of the inner end of the blade (3-3) is smaller than the width of the outer end.

The utility model has beneficial effects

The utility model arranges the blades eccentrically on the chassis, and the offset angle is adjustable, so that the width of fertilization can be adjusted flexibly, so that it can adapt to the fertilization requirements of crops with different row spacings;

The utility model increases the width of fertilizer spreading by adjusting the offset angle, without increasing the width of fertilizer spreading by increasing the rotating speed of the centrifugal disc, thereby reducing energy consumption and saving the cost of fertilizer spreading;

The utility model adopts 8 blades, so that more blades will contact the fertilizer per unit time during the fertilization process, push the fertilizer outward, and the fertilizer will be sprinkled to the area to be fertilized at a more stable flow rate, improving the uniformity of fertilization. sex.

The utility model places the outer edge of the feeding port above the outer contour of the flange, so that the fertilizer particles fall into the outer end of the flange on the centrifugal disc, avoiding the accumulation of fertilizer particles in the center of the centrifugal disc and affecting the efficiency of fertilizer spreading , so that the fertilizer is directly and smoothly pushed out to the area to be fertilized, which improves the efficiency of fertilization.

The utility model designs the feeding port as a hoof-like shape, so that the fertilizer forms a buffer during the falling process, avoiding that the fertilizer flow rate is too fast and directly falls on the centrifugal disc, causing impact on the centrifugal disc and affecting the rotation stability of the centrifugal disc. , so that the fertilizer can be spread out stably and evenly.

The utility model reduces the total mass of the blade by designing the blade so that the width of the inner end is smaller than the width of the outer end, thereby reducing the manufacturing cost of the blade and reducing the power consumption of the motor.

Detailed ways

Taking fertilization in tea gardens as an example below, the technical solution of the utility model will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the fertilizer box 1 is located at the top of the frame 2 and is connected by bolts; the centrifugal disc 3 is fixedly installed on the frame 2 and is positioned under the fertilizer box 1; The output shaft is matched; the centrifugal disc 3 is located directly below the feeding port.

As shown in Figure 2-1 and Figure 2-2, the centrifugal disc 3 of the present invention includes a flange 3-1, a chassis 3-2, and a blade 3-3; the blade 3-3 is arranged eccentrically on the chassis 3-2 Above; the inner end of the blade 3-3 is connected to the outer edge of the flange 3-1 through the hinge 3-5 and can rotate around the hinge 3-5, and the outer end of the blade 3-3 is fixed on the guide groove 3-1 with a detachable bolt 4. By loosening the bolts, the blade 3-3 can be slid circumferentially along the guide groove 3-4, thereby realizing the function of adjusting the offset angle of the blade 3-3.

As shown in Figure 3-1 and Figure 3-2, the top of the auxiliary feeding device 6 of the present invention is directly connected to the bottom of the fertilizer tank 1, and the bottom of the auxiliary feeding device 6 is matched with the feeding port 4.

As shown in Figure 4, the feeding port 4 is a hoof-like shape.

The working process of the utility model is : when fertilizing the tea garden, the fertilizer spreading device is fixed on the traction mechanism through the frame 2 and the DC motor 5 is powered on, and an appropriate amount of fertilizer is filled in the fertilizer box 1. During the fertilizer spreading process, under the action of the gravity of the fertilizer itself and the vibration of the machine, the fertilizer enters the feeding port 4 through the auxiliary feeding device 6 . Because the feed opening 4 is a hoof-like shape, the fertilizer will flow out slowly and evenly after being buffered, and fall on the centrifugal disc 3 . At this time, because the centrifugal disc 3 rotates at a constant speed under the drive of the DC motor 5, after the fertilizer falls on the centrifugal disc 3, it will be thrown into the tea garden at a certain speed under the promotion of the blades 3-3, and the fertilizer spreading is completed. process. Wherein, in the fertilizer spreading process, the width of the fertilizer spreading is adjusted by adjusting the offset angle of the blades 3-3 on the centrifugal disc 3, so that the fertilizer can accurately fall to the area to be fertilized between the tea rows according to the required width.

It should be noted that although the fertilization device of the present utility model is described in the description by taking the fertilization of tea gardens as an example, the use of the fertilization device is not limited to the situation described in the description. In actual use, it can also be used The above-mentioned fertilizer spreading device is used for other occasions.
