Description

Technical Field

[0001] The utility model relates to the field of fertilizer spreaders, in particular to a force-adding rod of a granular fertilizer multi-hole underground fertilizer spreader. Background Art

[0002] A multi-hole underground fertilizer applicator for granular fertilizer is a relatively common agricultural tool. The utility model patent application with publication number CN205727039U proposes a multi-hole underground fertilizer applicator for large fields, including a fertilizer box and a fertilizer spreader arranged on a frame, the fertilizer box is connected to the fertilizer spreader through a fertilizer guide tube; the fertilizer spreader includes a fertilizer applicator and a drill rod pusher, the fertilizer applicator includes a fertilizer barrel, one end of the fertilizer barrel is provided with a top opening and a side opening, and the other end is provided with a bottom opening, the fertilizer guide tube is connected with the top opening, and the outer edge of the bottom opening is provided with a contact plate, the drill rod pusher includes a drill rod and a pull rod for driving the drill rod, the drill rod is inserted into the fertilizer barrel from the side opening, and its specific working principle is that the fertilizer is first placed in the fertilizer box, and is introduced into the fertilizer barrel from the top opening through the fertilizer guide tube. The fertilizer barrel is inserted into the fertilizer barrel and falls on the ground through the bottom opening. The pulling rod or pushing rod is moved downward to make the fertilizer barrel contact the ground and stop moving. Then the pulling rod or pushing rod is continued to be moved, and the elastic component is deformed, so that the drill rod continues to be inserted into the side opening and inserted into the ground through the bottom opening of the fertilizer barrel, so that the fertilizer falling on the ground is pushed into the ground by the drill rod. When the drill rod is inserted into the fertilizer barrel, the fertilizer box is blocked from transporting fertilizer to the fertilizer barrel through the fertilizer guide pipe. After the drill rod pushes the fertilizer into the ground, the pulling rod or pushing rod is lifted to make the drill rod leave the ground, and the fertilizer barrel also leaves the ground. After the drill rod leaves the ground first and before the fertilizer barrel leaves the ground, the gravity of the fertilizer barrel causes the hole wall formed by the drill rod to collapse, thereby covering the hole formed by the drill rod with soil.

[0003] During the use of the above application, the main power source for inserting the drill rod into the ground and lifting it off the ground is achieved by manually pulling the pull rod or the push rod. This process is relatively laborious, and the manual control mainly applies force to the middle part of the drill rod pusher. It is difficult to ensure that the two drill rods are evenly stressed by manpower, especially when targeting different terrains, it is difficult to ensure uniform fertilization.

[0009] Preferably, a limit guide mechanism is also provided on both sides of the control hole of the operating rod in the middle of the control panel.

[0010] Preferably, the position limiting guide mechanism comprises connecting ribs arranged on both sides of the control hole, and the connecting ribs are provided with penetrating locking holes.

[0011] Preferably, the length of the connecting plate is adjustable.

[0012] Preferably, the control hole is rectangular.

[0013] The utility model can simultaneously apply force to two drill rods for hole opening, and can be applied manually and with foot pedal assistance, or with foot pedal alone. The force applied to the two drill rods is always consistent, and the hole opening depth can be basically consistent. In addition, the spacing between the drill rods is fixed, so that the spacing between the holes for fertilization is basically consistent, meeting the requirements of precise and accurate fertilization, adapting to the requirements of various field soils, and saving effort and time.

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2 As shown, a force adding rod of a granular fertilizer multi-hole underground fertilizer applicator is connected to the granular fertilizer multi-hole underground fertilizer applicator, the granular fertilizer multi-hole underground fertilizer applicator at least includes a drill rod 8 and a pull rod 10 driving the drill rod 8, and includes a control panel 1, the control panel 1 is provided with connecting holes 2 connected to the drill rod 8 at both ends, and the control panel 1 is provided with an operating rod control hole 3 connected to the pull rod 10 in the middle; it also includes a force adding part 4, and the force adding part 4 is fixedly connected to the control panel 1 through a connecting plate.

[0020] In a preferred embodiment of the present invention, the force-adding part 4 can generally be selected from the following Figure 3 The plate with arc-shaped edges shown is convenient for pressing and applying force with hands and feet, and can also be shaped to match the human foot.

[0021] In a preferred embodiment of the present invention, an anti-skid pad is provided on the upper surface of the force-applying part 4, generally a rubber pad is used, which can not only prevent skidding but also protect the hands and feet of a person, thereby improving the usability.

[0022] In a preferred embodiment of the utility model, the connecting plate is further provided with reinforcing ribs 5, which are generally arranged on both sides of the connecting plate to improve the load-bearing performance of the connecting plate and prevent deformation; the connecting plate directly adopts standard channel steel or I-beam.

[0023] In a preferred embodiment of the utility model, a limit guide mechanism is also provided on both sides of the operating lever control hole 3 in the middle of the control panel 1, and the limit guide mechanism includes connecting ribs 6 arranged on both sides of the control hole 3, and the connecting ribs 6 are provided with penetrating locking holes 7, and the locking holes 7 are provided with locking pins.

[0024] In a preferred embodiment of the utility model, the length of the connecting plate can be adjusted, and a structure similar to a telescopic rod can be adopted, which can be suitable for fertilizer spreaders of different specifications, but generally an integral structure is adopted to improve the load-bearing performance.

[0025] In a preferred embodiment of the present invention, the control hole 3 is rectangular.

[0026] When the above embodiment is used, the drill rod 8 is installed on the two connecting holes 2, and the drill rod 8 is fixed and locked at both ends of the connecting holes 2, the elastic component 9 is clamped on the limit guide mechanism, and then the locking pin is inserted into the locking hole 7 to lock the elastic component 9, and the connecting plate is adjusted so that the top of the pull rod 10 is against the bottom of the force-applying part 4. At this time, when the force is applied to the force-applying part 4, since all the components are locked, the whole will drive the drill rod 8 to move. When the two drill rods 8 are forced to open the hole downward by the booster pedal, the hand can step on the booster when the force is insufficient, or the foot can be stepped on alone. The upward operation rod drives the two drill rods 8 upward and back to their positions through the booster pedal, leaving the soil to form a hole in the soil, so that the granular fertilizer rolls to the bottom of the hole, saving effort and time, and improving the requirements of accurate and precise fertilization. In actual use, the original fertilizer applicator structure can be simplified, the elastic component 9 can be removed, and only the drill rod 8 can be fixed, and the same effect can be achieved, but at this time, the tops of the two drill rods 8 still need to be fixed and connected to ensure stability.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
