Description

Technical Field

[0001] The utility model relates to a fertilizer sprayer, in particular to a granular fertilizer sprayer for wheat planting, belonging to the technical field of fertilization devices. Background Art

[0002] A fertilizer sprayer is a fertilizer spraying tool used in agricultural production. Its main purpose is to spray fertilizer evenly onto the soil surface to ensure uniformity and coverage of fertilization. Before tilling the wheat field, fertilizer is usually sprayed onto the cultivated land using spraying equipment, and then a rotary tiller is used to shallowly till the cultivated land so that the fertilizer can be evenly distributed in the soil layer.

[0003] A Chinese patent with publication number CN216087606U discloses a fertilizer spreading device for agricultural planting.

[0004] Common granular fertilizer spreaders mainly include back bucket type and cart type, especially cart type granular fertilizer sprayers, which drive the spreading disc to rotate by pushing the wheels to rotate, and the granular fertilizer in the hopper falls onto the spreading disc through the feeding hole, and then the granular fertilizer is spread by the rotating spreading disc. In order to facilitate the control of the feeding rate, an adjustment mechanism for adjusting the size of the leakage gap is generally provided. However, the adjustment mechanism for adjusting the size of the leakage gap is generally composed of a connecting rod and a baffle set at the bottom of the hopper, and the controllability is poor. During the fertilizer spraying operation, the operator holds the handle of the cart and it is difficult to control the adjustment structure in time. When the cart stops, some fertilizer will flow out of the hopper and fall to the ground, which will cause great trouble to the fertilizer spraying operation. In addition, since the granular fertilizer will be affected by moisture during storage, which affects its fluidity, when the leakage gap is small, it is easy to cause the leakage gap to be blocked, which affects the fertilizer spraying work. Therefore, a granular fertilizer sprayer for wheat planting is proposed. Utility Model Content

Through an adjustment mechanism arranged on a handlebar, an operator can timely adjust the leakage gap and leakage rate of a leakage hole, or stop the leakage hole from leaking, thereby improving the control effect of the device and preventing the leakage gap of the leakage hole from being blocked by granular fertilizer when the leakage gap is small, thereby ensuring the smoothness of the fertilizer spraying operation.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0035] See also Figures 1 to 9 The utility model embodiment provides a granular fertilizer sprayer for wheat planting, a granular fertilizer sprayer for wheat planting, including a frame 1, two wheels 101 are arranged at the bottom of the frame 1, two handlebars 102 are fixed on the frame 1, a hopper 2 is fixed on the top of the frame 1, a gearbox 3 is installed at the bottom of the frame 1, a spreading disc 4 is fixed on the output shaft 305 of the gearbox 3, and the spreading disc 4 is located between the hopper 2 and the gearbox 3, and the two wheels 101 drive the spreading disc 4 to rotate through the gearbox 3 when rotating.

[0036] For details, please refer to Figure 2 , Figure 4 and Figure 7 The gearbox 3 includes a shell 301, and fixed cylinders 302 are fixed on both sides of the shell 301. The ends of the two fixed cylinders 302 away from the shell 301 are fixed to the frame 1. A bevel gear A304 is provided inside the shell 301.

The two ends of the rotating shaft 303 slide through the two fixed cylinders 302 and are fixedly connected to the two wheels 101.

[0037] The output shaft 305 of the gearbox 3 is rotatably set at the top of the shell 301, the top of the output shaft 305 is fixedly connected to the bottom of the spreading plate 4, the bottom end of the output shaft 305 extends to the inside of the shell 301 and is fixed with a bevel gear B306, the bevel gear B306 is meshed with the bevel gear A304, and the number of teeth of the bevel gear A304 is at least five times that of the bevel gear B306.

[0038] In the gearbox 3, pushing the frame 1 can make the two wheels 101 drive the rotating shaft 303, bevel gear A304, bevel gear B306, output shaft 305 and the material spreading plate 4 to rotate together. Because the number of teeth of bevel gear A304 is at least five times that of bevel gear B306, pushing the frame 1 can make the material spreading plate 4 rotate quickly.

[0039] For details, please refer to Figure 4 and Fig. 9 The material spreading plate 4 includes a support plate 401 fixed to the top of the output shaft 305 , a plurality of material shifting plates 403 are fixed to the upper surface of the support plate 401 , a baffle plate 402 is provided between every two adjacent material shifting plates 403 , and the baffle plate 402 is fixed to the upper surface of the support plate 401 .

[0040] Please refer to Figure 4 , Figure 5 and Figure 8 The bottom surface of the hopper 2 is provided with a leakage hole 5 corresponding to the position of the material spreading plate 4, and the bottom surface of the hopper 2 is fixed with a material guide box 201 corresponding to the position of the leakage hole 5, and the discharge port of the material guide box 201 corresponds to the position of the material spreading plate 4.

[0041] In the above scheme, when the granular fertilizer in the hopper 2 slides onto the spreading plate 4 through the leakage hole 5 and the guide box 201, the granular fertilizer can be scattered by the rapid rotation of the spreading plate 4.

[0042] The bottom surface of the hopper 2 is slidably provided with a baffle plate 6 corresponding to the position of the leakage hole 5, and the baffle plate 6 is slidably connected to the frame 1. An adjustment mechanism 7 for adjusting the horizontal position of the baffle plate 6 is provided on one of the handlebars 102. When the baffle plate 6 moves left and right, the leakage gap of the leakage hole 5 can be adjusted.

[0043] For details, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The adjusting mechanism 7 includes a connecting plate 701 fixed on the handlebar 102 and a limiting plate 704 rotatably connected to the handlebar 102. The middle part of the connecting plate 701 is slidably connected with a slide plate 702. A plurality of slots 703 are provided on the upper surface of the slide plate 702. A clamping portion corresponding to the slots 703 is provided at one end of the limiting plate 704. A spring 705 is fixed between the bottom surface of the other end of the limiting plate 704 and the handlebar 102. A threading tube 706 is fixed on the upper surface of the connecting plate 701. One end of the threading tube 706 is fixed to the frame 1 away from the connecting plate 701. A steel wire 707 is slidably provided inside the threading tube 706. One end of the steel wire 707 is fixedly connected to the slide plate 702, and the other end of the steel wire 707 is fixedly connected to the material blocking plate 6.

[0044] The adjusting mechanism 7 also includes a compression spring 708, one end of which is fixed on the frame 1, and the other end of the compression spring 708 is fixedly connected to the bottom surface of the material blocking plate 6 through a connecting block. Through the elastic force of the compression spring 708, the material blocking plate 6 moves to the right in a natural state to block the leakage hole 5.

[0045] In the adjustment mechanism 7, when it is not necessary to discharge materials, the left end of the limit plate 704 is pressed downward so that the limit plate 704 no longer limits the slide plate 702. At this time, the elastic force of the compression spring 708 is used to make the material blocking plate 6, the steel wire 707 and the slide plate 702 move rightward together, so that the material blocking plate 6 can completely block the material leakage hole 5, and the device can stop discharging materials. When it is necessary to discharge materials, the slide plate 702 is pulled leftward so that the clamping part of the right end of the limit plate 704 is located in different clamping grooves 703, so that the blocking area of ​​the material blocking plate 6 on the material leakage hole 5 can be adjusted to adjust the material leakage gap and leakage rate of the material leakage hole 5, thereby improving the control effect of the device.

[0046] Please refer to Figure 4 , Figure 5 , Figure 6 and Fig. 9The bottom surface of the hopper 2 is rotatably connected with a rotating rod 8, the top of the rotating rod 8 extends to the inside of the hopper 2 and is fixed with a lever 9, and the lever 9 corresponds to the position of the leakage hole 5, the bottom end of the rotating rod 8 extends to the bottom of the hopper 2 and is fixed with a strip plate 10, and a strip hole 11 is opened inside the strip plate 10, and a concentric shaft 12 is fixed on the top of the scattering disc 4, and an eccentric rod 13 is fixed on the top of the concentric shaft 12, and the top of the eccentric rod 13 is slidably arranged inside the strip hole 11. When the scattering disc 4 rotates, it can drive the concentric shaft 12 and the eccentric rod 13 to rotate together, because the top of the eccentric rod 13 is slidably arranged inside the strip hole 11, so when the eccentric rod 13 rotates, it can make the strip plate 10 and the lever 9 swing left and right with the rotating rod 8 as the axis, and through the left and right swing of the lever 9, the granular fertilizer above the leakage hole 5 can be moved to avoid being blocked by the granular fertilizer when the gap of the leakage is small.

[0047] When the utility model is used: pour the granular fertilizer into the hopper 2, and use the adjustment mechanism 7 to adjust the feeding rate of the granular fertilizer (the principle is described above). Because the adjustment mechanism 7 is installed on the handlebar 102, the operator can timely adjust the leakage gap and leakage rate of the leakage hole 5, or stop the leakage hole 5 from leaking, thereby improving the control effect of the device. The device is pushed to move by the handlebar 102, and while the wheel 101 rotates, the material spreading plate 4 can be driven to rotate through the gearbox 3, and the granular fertilizer in the hopper 2 falls onto the material spreading plate 4 through the leakage hole 5 and the guide box 201. Under the rotation of the material spreading plate 4, the granular fertilizer is thrown around, so that the device can spray the granular fertilizer during the movement. During the spraying process of the granular fertilizer, when the spreading disc 4 rotates, it can drive the concentric shaft 12 and the eccentric rod 13 to rotate together. Since the top end of the eccentric rod 13 is slidably arranged inside the strip hole 11, when the eccentric rod 13 rotates, the strip plate 10 and the shift rod 9 can swing left and right with the rotating rod 8 as the axis. Through the left and right swing of the shift rod 9, the granular fertilizer above the leakage hole 5 can be moved to avoid the leakage hole 5 being blocked by the granular fertilizer when the leakage gap is small, thereby ensuring the smoothness of the fertilizer spraying operation.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
