Description

A multifunctional fertilizer spreader

technical field

The invention relates to a fertilizer spreader, in particular to a multifunctional fertilizer spreader, which belongs to the technical field of agricultural machinery.

Background technique

Powder fertilizer and organic granular fertilizer have the properties of small particle size, high humidity, and poor fluidity, so it is difficult to spread them with traditional disc fertilizer spreaders. At present, my country's powder fertilizer and organic granular fertilizer have not yet formed a unified market classification standard, thus hindering the development of special fertilizer spreaders. According to the applicant's understanding, the existing powder fertilizer and organic granular fertilizer spreaders cannot guarantee the continuity and uniformity of fertilizer discharge, and have the disadvantages of slow operation speed and low efficiency.

Contents of the invention

The purpose of the present invention is: aiming at the shortcomings of the above-mentioned prior art, propose a multifunctional fertilizer spreader that can realize the continuous and uniform spreading of various fertilizers, so as to solve the problem of spreading powder fertilizer and organic granular fertilizer.

In order to achieve the above object, the multifunctional fertilizer spreader of the present invention has an open top collecting box fixed on the frame, and the collecting box is fixedly connected by the upper frustum-shaped hollow box and the lower conical hollow lower chamber Form a funnel-shaped structure, the bottom surface of the box has leakage holes distributed in the circumferential direction, a C-shaped gasket is sandwiched between the upper end of the lower chamber and the bottom surface of the box, and a circumferential gasket is installed in the C-shaped gasket. The discharge adjustment plate to the degree of freedom, the discharge adjustment plate has a discharge hole corresponding to the leakage hole on the bottom surface of the box, and has an adjustment handle extending from the opening of the C-shaped gasket, the lower chamber A circular tube-shaped discharge chute extends from the bottom of the trough, and a rotatable fertilizer spreader disc is installed below the discharge trough to form a discharge interval. The upper surface of the fertilizer spreader disc is installed with a semicircular top plate and a semicircular The disc cover plate composed of peripheral baffles, the semicircular top plate is located in the middle of the axial outer circle of the discharge chute, the center of the collection box is equipped with a vertical rotatable main shaft, and the upper end of the main shaft is fixed on the The conical cap above the bottom surface of the collecting box, the middle part of the main shaft has a helical blade located in the discharge trough, and the lower end of the helical blade has a baffle plate radially extending from the discharge interval on the fertilizer spreading disc .

When working, the power source drives the main shaft to drive the conical cap, spiral blade and baffle to rotate. With the help of the discharge adjustment plate, the angular relative position of the leakage hole and the discharge hole can be adjusted as required to form a through hole of appropriate size. Under the loosening of the conical cap and the vibration when the machine is moving, the fertilizer entering the box will pass through the through hole formed by the leakage hole and the discharge hole as required, and fall into the lower chamber. It falls on the upper surface of the fertilizer spreading disc, and is centrifugally thrown out from the opening direction of the disc cover under the action of the rotating and dialing of the fertilizer spreading disc and the baffle, and spreads to the field.

The invention not only rationally divides the collection box into upper and lower chambers, but also loosens the fertilizer in the box by the rotation of the conical cap, and properly controls the amount of fertilizer falling into the lower chamber by means of the adjustment of the leakage hole and the discharge hole. , and then conveyed by screw to ensure the continuous output of the fertilizer in the lower chamber, and finally evenly spread to the field by the fertilizer spreading mechanism. The above measures cooperate with each other to effectively avoid the blockage of various fertilizers, thereby effectively solving the problem of powder fertilizer and organic granular fertilizer spreading, and ensuring the continuous and uniform spreading of fertilizers.

A further perfection of the present invention is that the two ends of the semi-circumferential baffles of the disc cover plate are respectively hinged with amplitude-modulating plates with adjustable deployment angles through vertical hinges. In this way, the width of fertilizer spreading can be controlled within a certain range, and the uniformity of fertilizer spreading can be improved.

In order to facilitate assembly, the tubular discharge chute is formed by combining two semicircles.

Detailed ways

Embodiment one

As shown in Figure 1, Figure 2 and Figure 8, the multifunctional fertilizer spreader of the present embodiment has an open top collecting box fixed on the frame, and the collecting box consists of an upper frustum-shaped hollow box 7 and a lower one. The conical hollow lower chamber 5 is fixedly connected to form a funnel-shaped structure. The bottom surface of the box body 7 has leakage holes distributed in the circumferential direction, and the C-shaped gasket 6 shown in Figure 5 is sandwiched between the upper end of the lower chamber 5 and the flange edge of the bottom surface of the box body 7. In the C-shaped gasket Install the discharge adjustment plate 11 located between the lower chamber 5 and the flange side of the casing 7, but have a circumferential degree of freedom. The discharge adjustment plate 11, as shown in Figure 4, has Corresponding to the leakage hole, there are four rectangular discharge holes evenly distributed around the circumference, and there is an adjustment handle extending from the opening of the C-shaped gasket 6 . The bottom of the lower chamber 5 extends out of a circular tubular discharge chute 4 formed by overlapping semicircles. A rotatable fertilizer spreader 8 forming a discharge interval is installed below the discharge trough 4. The top of the fertilizer spreader 8 is The surface is installed with a disc cover plate 3 composed of a semicircular top plate 3-1, a semicircular baffle plate 3-2 and a bottom support plate 3-3 (see Fig. 6 and Fig. 8), and the semicircular top plate is located at the discharge chute 4 In the middle part of the axial outer circle, the center of the collection box 7 is equipped with a vertical external power-driven rotatable main shaft 1, the upper end of which is fixed on the conical cap 2 above the bottom surface of the collection box 7, and the middle part of the main shaft 1 has The screw blade 10 located in the discharge trough 4, the lower end of the screw blade 10 has a baffle plate 9 extending radially from the discharge interval on the fertilizer spreading disc 8, the main shaft 1, the screw blade 10, the baffle plate 9 and the sprinkling The fat disc 8 constitutes the main shaft assembly shown in FIG. 3 . The two ends of the semi-circumferential baffle of the disk cover plate 3 are respectively hinged with an adjustable amplitude modulation plate 2 (see Figure 7) through a vertical hinge. The arc track groove 13 constitutes a lockable moving pair, so the opening angles of the two amplitude modulation plates 2 can be adjusted within a certain range to control the width of fertilizer spreading and further improve the uniformity of fertilizer spreading.

Practice has proved that when working, the driving force is transmitted to the main shaft 1 through the gearbox, driving the fertilizer spreading disc 8, the baffle plate 9, the spiral blade 10 and the conical cap 12 to rotate together. The bottom surface of the body 7 maintains an appropriate split discharge channel. Under the rotation and vibration of the cone top and its own gravity, the fertilizer falls from the discharge channel to the lower chamber 5, and the rotating helical blade 10 quantitatively transports the fertilizer to the On the fertilizing disc 8, under the action of centrifugal force and the thrust of the baffle 9, the fertilizing disc 8 flies out, so that various fertilizers, including various difficult-to-fertilize, can be continuously and evenly spread to the field ground, and It has a compact structure and is easy to assemble. It is suitable for spreading inorganic powder fertilizer, granular fertilizer and organic granular fertilizer. The spreading is uniform and reliable, saving time and effort.
