Description

Technical Field

[0001] This invention relates to the field of farmland fertilization equipment technology, and in particular to a disc-type hole-punching fertilization mechanism. Background Technology

[0002] Fertilization is typically carried out during the growth process of crops to improve soil fertility and meet their growth needs. Traditional fertilization methods mainly include broadcasting and furrowing. Broadcasting results in some fertilizer volatilizing on the surface, leading to low utilization. Furrowing can effectively solve the shortcomings of broadcasting, but it accelerates the loss of soil moisture and can damage crop roots during the furrowing process, affecting normal crop growth. Therefore, more professional and efficient hole-punching fertilizer applicators have emerged on the market to replace traditional fertilization methods. The hole-punching fertilizer applicator in this type of fertilizer applicator is the core component and the last important step in achieving fertilization, which directly affects the fertilization effect and efficiency. Existing hole-punching fertilizer applicators mainly use the method of driving the hole-punching duckbill to move up and down to punch fertilizer, which is not very efficient. Due to the unevenness of the ground surface, this method of hole-punching fertilizer applicator often results in uneven hole depth, which cannot guarantee the fertilization effect. In addition, an independent fertilizer discharge device is required to discharge fertilizer into the hole-punching duckbill, making the overall structure of the hole-punching fertilizer applicator complex and not compact. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a disc-type hole-drilling fertilization mechanism.

[0004] The technical solution of the present invention is: a disc-type hole-punching fertilizer application mechanism, comprising a rotating disc with an internal receiving cavity, a hole-punching duckbill assembly, and an opening and closing mechanism;

[0005] A first feed inlet is provided at the center of one end plate of the rotating disk, and a feed pipe is rotatably connected to the first feed inlet. A wheel axle for supporting the rotation of the rotating disk is provided between the centers of the two end plates of the rotating disk. Several discharge ports are evenly distributed in the middle of the side plates of the rotating disk. Each discharge port is provided with a hole-punching duckbill assembly. The hole-punching duckbill assembly includes a fixed duckbill and a movable duckbill. The fixed duckbill is fixed radially at the discharge port. The upper end of the movable duckbill is fixedly connected to a hinge shaft and is hinged to the fixed duckbill through the hinge shaft. The duckbill cavity formed by the fixed duckbill and the movable duckbill covers the discharge port.

[0006] The opening and closing mechanism includes a Z-shaped bracket fixed to the lower end of the feed pipe, a guide wheel assembly, and a stop bar. The support plate at the lower end of the Z-shaped bracket is parallel to the end plate of the rotating disk, and an arc-shaped groove is provided at the inner end of the support plate. A limiting flange is provided at the lower edge of the outer end of the support plate. The guide wheel assembly includes a swing plate and several guide wheels. A circular protrusion is provided at the lower corner of the inner end of the support plate. The upper end of the swing plate is hinged to the circular protrusion. Several guide wheels are rotatably connected to the middle of the inner side of the swing plate along the length direction. The guide wheel at the upper end of the swing plate can correspond to the arc-shaped groove, and the guide wheel at the lower end of the swing plate can correspond to the limiting flange. The stop bar is arranged radially on the outer side of the end face of the rotating disk. The lower end of the stop bar is vertically fixed to the hinge shaft of the movable duckbill, and the upper end of the stop bar can correspond to the guide wheel at the lower end of the swing plate. A torsion spring for driving the movable duckbill to close counterclockwise is provided between the stop bar and the hinge shaft.

[0007] Preferably, the inner side of the swing plate is provided with a protective baffle, which blocks the space between the stop wheel and the limiting fold.

[0008] Preferably, a buffer box is provided at the discharge port inside the rotating disc, the discharge port is located at one end of the buffer box, a second feed port is provided in the middle of one side plate of the buffer box, an inclined baffle is provided on the outside of the second feed port, and a top plate is provided between the upper end of the inclined baffle and the side plate of the buffer box, forming a funnel-shaped feed channel communicating with the second feed port between the top plate, the inclined baffle and the side plate of the buffer box.

[0009] Preferably, the end plate of the rotating disk is provided with an adjustment mechanism for controlling the size of the flared feed channel opening. The adjustment mechanism includes an adjustment plate and a drive motor. The upper end face of the adjustment plate is provided with a horizontal shaft along the length of the rectangular section. The size of the adjustment plate matches the cross-sectional size of the flared feed channel. The adjustment plate is rotatably connected to the inlet of the flared feed channel via the horizontal shaft. The drive motor is mounted on the side plate of the rotating disk via a U-shaped bracket. The drive shaft of the drive motor is coaxially and fixedly connected to one end of the horizontal shaft.

[0010] Preferably, the end plate of the rotating disc is provided with circular gear scale lines, and an indicator disc is coaxially fixedly connected to the drive shaft of the drive motor, with the indicator tip on the indicator disc corresponding to the gear scale lines.

[0011] Preferably, the buffer box is rectangular, with one end smaller than the other, and the smaller end of the buffer box corresponds to the discharge port. An inclined side plate connects the two ends of the buffer box.

[0012] Preferably, a transparent plate is provided in the middle of one end plate of the rotating disk, through which the internal condition of the rotating disk can be observed.

[0013] The beneficial technical effects of this invention are:

[0014] First, this invention designs a disc-type hole-punching fertilization mechanism. The mechanism has a cavity inside a rotating disc for temporarily storing fertilizer. Several hole-punching beak assemblies connected to the cavity are located on the side (rolling surface) of the rotating disc. As the disc rolls across the ground, these beaks sequentially punch fertilization holes. Simultaneously, the beak assemblies are opened by an opening and closing mechanism, allowing the fertilizer temporarily stored in the cavity to enter the punched fertilization holes. Then, the beak assemblies automatically close under the action of a torsion spring, completing the hole-punching fertilization operation. This disc-type hole-punching fertilization mechanism perfectly adapts to uneven ground, ensuring consistent hole depth and fertilizer application, thus improving fertilization efficiency and guaranteeing fertilization effectiveness.

[0015] Secondly, the retaining wheel assembly of the opening and closing mechanism of this invention is rotatably connected to the lower end of the support plate. Therefore, the retaining wheel assembly can swing in both clockwise and counterclockwise directions. When the rotating disc moves forward clockwise to apply fertilizer, the upper end of the stop rod blocks the lower end of one side of the retaining wheel assembly and pushes the retaining wheel assembly to rotate clockwise. When the retaining wheel contacts the limiting flange, it generates resistance to the stop rod, and the stop rod swings accordingly to open the fertilizing duckbill assembly for fertilization. After fertilization is completed, the upper end of the stop rod slides past the lower end of the retaining wheel assembly, and the torsion spring causes the fertilizing duckbill assembly to close again. The mechanism automatically opens and closes the piercing duckbill assembly. Simultaneously, it can handle the counter-clockwise rotation of the rotating disc during reversing. When the disc rotates counter-clockwise, the upper end of the stop lever blocks the lower end of the other side of the guide wheel assembly, pushing the guide wheel assembly to rotate counter-clockwise. The piercing duckbill assembly is in a closed state under the action of the torsion spring. When the upper end of the guide wheel assembly rotates into the arc-shaped groove, the stop lever and the lower end of the guide wheel assembly separate. During this process, there is no conflict between the guide wheel assembly and the stop lever, thus achieving counter-clockwise rotation of the piercing fertilizer application mechanism during reversing.

[0029] Example 1, see appendix to the instruction manual. Figure 1- 12, A disc-type hole-punching fertilizer applicator, mainly used for fertilization on a tractor, comprising a rotating disc with an internal receiving cavity, a hole-punching beak assembly, and an opening and closing mechanism; a first feed inlet is provided at the center of one end plate of the rotating disc, and a feed pipe is rotatably connected to the first feed inlet, with a rotary sealing ring at the rotatable connection; the feed pipe is connected to a fertilizer box; when the rotating disc rotates, the feed pipe is in a relatively stationary state; a wheel axle is provided between the centers of the two end plates of the rotating disc to support the rotation of the rotating disc; one end of the wheel axle extends from the first feed inlet into the feed pipe, and exits from the feed pipe... The lower part extends outwards, and a bearing is provided between the lower part of the feed pipe and the axle. A bearing is also provided between the axle and the end plate of the rotating disc. Several discharge ports are evenly distributed in the middle of the side plate of the rotating disc. Each discharge port is equipped with a hole-punching duckbill assembly. The hole-punching duckbill assembly includes a fixed duckbill and a movable duckbill. The fixed duckbill is fixed radially at the discharge port. The upper end of the movable duckbill is fixedly connected to a hinge shaft and is hinged to the fixed duckbill through the hinge shaft. The duckbill cavity formed by the fixed duckbill and the movable duckbill covers the discharge port. The fertilizer in the cavity enters the duckbill cavity from the discharge port. After the hole is punched, the soil can automatically backfill.

[0030] The opening and closing mechanism includes a Z-shaped bracket fixed to the lower end of the feed pipe, a guide wheel assembly, and a stop bar. The support plate at the lower end of the Z-shaped bracket is parallel to the end plate of the rotating disk, and an arc-shaped groove is provided at the inner end of the support plate. A limiting flange is provided at the lower edge of the outer end of the support plate. The guide wheel assembly includes a swing plate and several guide wheels. A circular protrusion is provided at the lower corner of the inner end of the support plate. The upper end of the swing plate is hinged to the circular protrusion. Several guide wheels are rotatably connected to the middle of the inner side of the swing plate along the length direction. The guide wheels at the upper end of the swing plate can correspond to the arc-shaped groove. To increase the swing space of the baffle wheel assembly, the baffle wheel at the lower end of the swing plate can correspond to the limiting flange, which is used to limit the swing range of the baffle wheel assembly. The baffle rod is arranged radially on the outer side of the end face of the rotating disk. The lower end of the baffle rod is vertically fixedly connected to the hinge shaft of the movable duckbill. The swing of the baffle rod can drive the movable duckbill to rotate inside the fixed duckbill through the hinge shaft, so as to realize the opening or closing of the puncture duckbill assembly. The upper end of the baffle rod can correspond to the baffle wheel at the lower end of the swing plate. A torsion spring is provided between the baffle rod and the hinge shaft to drive the movable duckbill to close counterclockwise.

[0031] The inner side of the swing plate is provided with a protective baffle. This protective baffle is between the stop wheel and the limiting folded edge to protect the stop wheel, avoid damage caused by frequent collisions between the stop wheel and the limiting folded edge, and help extend the service life of the stop wheel.

[0032] A buffer box is provided at the discharge port inside the rotating disc. The discharge port is located at one end of the buffer box. A second inlet is provided in the middle of one side plate of the buffer box. An inclined baffle is provided on the outside of the second inlet. A top plate is provided between the upper end of the inclined baffle and the side plate of the buffer box. A funnel-shaped feeding channel communicating with the second inlet is formed between the top plate, the inclined baffle, and the side plate of the buffer box. When the rotating disc rotates, the fertilizer in the receiving cavity flows into the funnel-shaped feeding channel along the inner side wall of the rotating disc. The funnel-shaped feeding channel is used to guide the fertilizer to the second inlet and enter the buffer box from the second inlet, which can improve the feeding speed of the buffer box and ensure the feeding amount of the buffer box.

[0033] The rotating disc has an adjustment mechanism on its end plate for controlling the size of the funnel-shaped feed channel opening. The mechanism includes an adjustment plate and a drive motor. A horizontal shaft is located along the length of the upper surface of the adjustment plate, matching the cross-sectional dimensions of the funnel-shaped feed channel. The adjustment plate is rotatably connected to the inlet of the funnel-shaped feed channel via the horizontal shaft. The drive motor is mounted on the side plate of the rotating disc via a U-shaped bracket, and its drive shaft is coaxially fixedly connected to one end of the horizontal shaft. The end plate of the rotating disc has circular gear scale lines. An indicator disc is coaxially fixedly connected to the drive shaft of the drive motor, with the indicator arrows on the indicator disc corresponding to the gear scale lines. The drive motor drives the horizontal shaft at the top of the adjustment plate to rotate, causing the adjustment plate to swing and adjust the size of the funnel-shaped feed channel opening. Simultaneously, the indicator disc rotates synchronously with the horizontal shaft, and the indicator arrows on the indicator disc point to different gear scale lines. The size of the opening is adjusted based on the gear scale lines, allowing for precise control of the fertilizer application rate.

[0034] The lower outer corner of the adjustment plate is provided with a beveled edge, which can change the flow direction of fertilizer and play a turbulent role. It can not only break up the clumps of fertilizer, but also prevent fertilizer from clogging at the entrance of the funnel-shaped feed channel. A transparent plate is provided in the middle of one end plate of the rotating disk, through which the internal situation of the rotating disk can be observed.

[0035] The buffer box is rectangular in shape, with one end smaller than the other, and the smaller end of the buffer box corresponds to the discharge port. A sloping side plate connects the two ends of the buffer box. This design maximizes the storage space of the buffer box and ensures that the stored fertilizer is completely discharged from the discharge port. The sloping side plate acts as a guide, facilitating the rapid flow of fertilizer from the buffer box to the discharge port.

[0036] The working process and principle of this invention are as follows:

[0037] When the hole-punching fertilization mechanism rotates clockwise to perform hole-punching fertilization operations (see attached diagram in the instruction manual), Figure 3 )

[0038] Fertilizer enters the receiving cavity of the rotating disc through the feed pipe. As the disc rotates, the fertilizer in the receiving cavity enters the buffer box through the funnel-shaped feed channel, and then enters the hole-piercing duckbill assembly through the discharge port inside the buffer box. Simultaneously, the hole-piercing duckbill assembly at the lower end of the side (rolling surface) of the rotating disc pierces deep holes in the ground. While piercing holes, the stop rod connected to the movable duckbill rotates clockwise with the rotating disc. When the upper end of the stop rod contacts the stop wheel at the lower end of the stop wheel assembly, it pushes the stop wheel assembly to rotate clockwise. After the limiting flange on the component and support plate contacts, the swinging stops. At this time, the stop bar is obstructed and begins to swing, driving the hinge shaft to rotate and open the movable duckbill. The fertilizer inside is applied into the deep hole. During the fertilization process, the stop bar continues to swing and slides past the lower end of the stop wheel component. The torque of the torsion spring causes the hole-punching duckbill component to close again. After the hole-punching duckbill component leaves the fertilization hole, the soil automatically backfills to cover the fertilizer inside. This opening and closing mechanism can automatically realize the opening and closing of the hole-punching duckbill component for fertilization, ensuring the fixed-plant and fixed-quantity fertilization of this fertilization mechanism.

[0039] When the fertilization hole-punching mechanism reverses and rotates counterclockwise (see attached diagram in the instruction manual), it will be effective. Figure 4 )

[0040] When the rotating disc rotates counterclockwise, the stop lever rotates counterclockwise as well. At this time, the torsion spring keeps the hole-punching duckbill assembly in a closed state. When the upper end of the stop lever contacts the lower end of the stop wheel assembly, it can push the stop wheel assembly to rotate counterclockwise. When the upper end of the stop wheel assembly rotates into the arc groove, the upper end of the stop lever disengages from the lower end of the stop wheel assembly. During this process, the stop wheel assembly will not trip the upper end of the stop lever, thus realizing the counterclockwise rotation of the hole-punching fertilizer application mechanism when reversing.
