Description

Technical Field

[0001] The utility model relates to the technical field of greening planting, in particular to a lawn fertilizing device capable of evenly applying fertilizer. Background Art

[0002] A lawn is a grassy area that is artificially planted or maintained for landscaping purposes. It is used for beautifying the environment, landscape design, air purification, soil and water conservation, and as a venue for outdoor activities and sports. Lawns are typically not planted directly or sown, as this would take too long to establish. Instead, pre-grown turf is typically purchased and laid directly onto the surface. During the planting process, turf manufacturers perform regular maintenance, including but not limited to watering, fertilizing, and mowing, to ensure the lawn's condition.

[0003] Broadcasting is a relatively simple and widely used method for fertilizing lawns. Fertilizer is spread across the lawn surface, then dissolved by watering or rainwater, seeping into the soil. Prior art typically uses a motor to drive a distribution disc, which distributes the fertilizer onto the lawn. This motor requires power, typically from batteries, which require frequent battery replacement and increase the weight of the equipment. Furthermore, the distribution disc is typically conical and smooth, utilizing centrifugal force to distribute the material, but this limits the distance over which it can be dispersed.

[0029] Example 1:

[0030] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A lawn fertilizing device capable of evenly applying fertilizer, comprising:

[0032] The fertilizer spreading vehicle 1 includes a fertilizer box 11, a wheel 12 is rotatably mounted on the bottom of the fertilizer box 11 through a wheel axle 13, a discharge port 14 is provided at the bottom of the fertilizer box 11 and behind the wheel 12, a discharge port switch 2 is provided below the discharge port 14, a spreading assembly 3 is provided below the discharge port switch 2, and the spreading assembly 3 is connected to the wheel axle 13.

[0033] The fertilizer box 11 is used to store fertilizer, and the wheels 12 are used to move the fertilizer spreading vehicle 1. When the wheels 12 rotate, they can drive the wheel shaft 13 to rotate.

[0034] A handle 16 is welded to the top of the rear side of the fertilizer box 11 .

[0035] The handle 16 is used to push the fertilizer box 11 to move.

[0036] A support rod 15 is welded to the rear side of the bottom of the fertilizer box 11 , and the bottom surface of the support rod 15 is higher than the lower edge of the wheel 12 .

[0037] The support rod 15 is used to support the fertilizer spreading vehicle 1 when not in use.

[0038] The discharge port switch 2 includes a discharge baffle 21, which is slidably installed below the discharge port 14 through a guide groove 22. The discharge baffle 21 is connected to a control component, which is used to control the sliding distance of the discharge baffle 21, thereby controlling the opening size of the discharge port 14.

[0039] The discharge baffle 21 can block the discharge port 14, thereby preventing the fertilizer from sliding. When the discharge baffle 21 slides toward the tail end of the guide groove 22, the discharge port 14 loses its shielding, and the fertilizer slides down under the action of gravity.

[0040] The tail of the discharge baffle 21 passes through the guide groove 22 and is connected to the limit plate 25 . The tail end of the limit plate 25 is connected to the control line 26 . The tail end of the control line 26 is connected to the adjustment slide rod 28 . The adjustment slide rod 28 is slidably connected to the handle 16 .

[0041] The control line 26 passes through the middle of the adjusting slide rod 28 and is fixedly connected to the adjusting slide rod 28 .

[0042] Applying a force away from the fertilizer box 11 to the adjusting slide rod 28 can drive the adjusting slide rod 28 to slide, thereby driving the discharge baffle 21 to slide toward the tail end of the guide groove 22 through the control line 26, thereby opening the discharge port 14.

[0043] A guide rod 23 is welded to the bottom surface of the discharge baffle 21 , which passes through the tail end of the guide groove 22 and is slidably connected to the guide groove 22 . A return spring 24 is sleeved on the guide rod 23 , and the tail end of the return spring 24 is against the guide groove 22 .

[0044] When the discharge baffle 21 slides toward the rear end of the guide groove 22, it compresses the return spring 24, which reduces the external force applied to the adjustment slide rod 28, and the discharge baffle 21 slides under the elastic force of the return spring 24. Therefore, by controlling the external force applied to the adjustment slide rod 28, the position of the discharge baffle 21 can be controlled, thereby controlling the opening size of the discharge port 14 and further controlling the discharge amount.

[0045] When the adjusting slide rod 28 is completely released, the discharge baffle 21 will completely close the discharge opening 14 under the elastic force of the return spring 24, thereby realizing automatic closing of the discharge opening 14.

[0046] The discharge port switch 2 further includes a plurality of pulley blocks 27 , which are fixedly mounted on the rear side of the fertilizer box 11 and the ground, and the control line 26 passes around the pulley blocks 27 .

[0047] The pulley block 27 is used to change the direction of the control line 26 while preventing the control line 26 from rubbing against the fertilizer box 11 .

[0048] The spreading assembly 3 includes a spreading tray 36, and a number of spreading baffles 37 are evenly arranged on the top surface of the spreading tray 36. A second transmission shaft 33 is clamped in the middle of the spreading tray 36. The second transmission shaft 33 passes through the fertilizer box 11 upward and is fixedly connected to an arc-shaped pushing plate 35. The second transmission shaft 33 is connected to the wheel axle 13 through a transmission device, and the wheel axle 13 can drive the second transmission shaft 33 to rotate through the transmission device.

[0049] The rotation of the second transmission shaft 33 can simultaneously drive the arc-shaped push plate 35 and the spreading plate 36 to rotate.

[0050] The arc-shaped push plate 35 can stir the fertilizer above the discharge port 14 to prevent the fertilizer from clogging the discharge port 14 .

[0051] The material spreading plate 36 is conical, and the material spreading baffle 37 is spiral.

[0052] When the spreading plate 36 rotates, the fertilizer can slide downward and outward along the slope of the top surface of the spreading plate 36, and at the same time rotate under the drive of the spreading baffle 37. The spiral spreading baffle 37 can extend the rolling distance of the fertilizer and increase the angular velocity of the fertilizer, thereby increasing the spreading distance of the fertilizer and making the fertilizer spreading more uniform.

[0053] The transmission device includes a first transmission shaft 31 , the end of the first transmission shaft 31 is connected to the wheel shaft 13 through a first bevel gear assembly 32 , and the tail end of the first transmission shaft 31 is connected to the second transmission shaft 33 through a second bevel gear assembly 34 .

[0054] When the fertilizer spreading vehicle 1 moves, the wheel 12 can drive the wheel shaft 13 to rotate. The rotation of the wheel shaft 13 can drive the first transmission shaft 31 to rotate through the first bevel gear assembly 32, thereby driving the second transmission shaft 33 to rotate through the second bevel gear assembly 34.

[0055] It should be noted that the first bevel gear assembly 32 is composed of two meshing bevel gears, one large and one small. The larger bevel gear is engaged with the wheel shaft 13, and the smaller bevel gear is engaged with the first transmission shaft 31, thereby increasing the rotation speed of the first transmission shaft 31. The second bevel gear assembly 34 is composed of two meshing bevel gears of the same size.

[0056] When the operator of this embodiment uses this device, he puts fertilizer into the fertilizer box 11.

[0057] Hold the crossbar of the handle 16 and the adjusting slide rod 28 with both hands, and apply a thrust to the handle 16 to push the fertilizer spreading vehicle 1 to move.

[0058] At the same time, the gripping force of both hands is used to drive the adjustment slide rod 28 to slide toward the horizontal bar direction of the handle 16, and the discharge baffle 21 is driven to slide toward the tail end of the guide groove 22 through the control line 26, thereby opening the discharge port 14.

[0059] The gripping force of both hands is controlled, and the position of the discharge baffle 21 is adjusted in conjunction with the return spring 24 to control the opening size of the discharge port 14 and thus control the discharge amount.

[0060] When the fertilizer spreading vehicle 1 moves, the wheel 12 can drive the wheel shaft 13 to rotate. The rotation of the wheel shaft 13 can drive the first transmission shaft 31 to rotate through the first bevel gear assembly 32, thereby driving the second transmission shaft 33 to rotate through the second bevel gear assembly 34.

[0061] The rotation of the second drive shaft 33 simultaneously drives the arc-shaped push plate 35 and the spreading plate 36. As the spreading plate 36 rotates, the fertilizer slides downward and outward along the slope of its top surface while being driven by the spreading baffle 37. The spiral-shaped spreading baffle 37 extends the rolling distance of the fertilizer and increases its angular velocity, thereby increasing the fertilizer's spreading distance and making it more evenly distributed.

[0062] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
