Description

Technical Field

[0001] The utility model relates to the technical field of fertilizing machinery, in particular to a crop fertilizing device. Background Art

[0002] In the process of crop planting, it is often necessary to fertilize the crops to ensure their growth. At present, when fertilizing crops, it is usually relied on manual sowing and fertilization. This method of fertilization has high labor intensity and low fertilization efficiency. Based on this, the relevant technology has been improved. For example, patents such as CN201711185818.5 and CN201710703724.6 provide a fertilizer vehicle, and the amount of fertilizer applied by the fertilizer vehicle can be adjusted. However, the fertilization adjustment structure of this type of scheme uses an electric control structure, which is mostly achieved with the help of an electric control valve.

[0003] However, when applying fertilizer outdoors, the electronic control structure is expensive, and its reliability is not high after being exposed to wind and sun, and it is easy to break down. In addition, it is inconvenient to power supply outdoors. This type of fertilizer vehicle also requires additional batteries, and the overall structure is bloated and not practical, so it needs to be optimized and improved. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] like Figure 1-Figure 5 The crop fertilizing device shown comprises a fertilizing cart, a fertilizer box 5 and a lever discharging mechanism.

[0025] The fertilizer cart is a commonly used cart in the prior art, including a frame 1 and wheels 2 rotatably arranged on the frame 1. The cart can be a wheelbarrow, a two-wheeled cart, etc., which is not limited here, and those skilled in the art can choose according to actual needs. In this solution, a placement frame 3 is provided on the front side of the frame 1 of the fertilizer cart, and a handle 4 is provided on the rear side.

[0026] The fertilizer box 5 can be detachably placed on the placement rack 3, that is, the fertilizer box 5 and the placement rack 3 are not fixed together, but are detachable, so that the fertilizer box 5 can be removed for cleaning and replacement in the later use. Figure 2-Figure 4As shown, the placement rack 3 is an annular rack, and the outer peripheral edge of the upper end of the fertilizer box 5 is provided with an annular flange 7, so that when the fertilizer box 5 is placed in the annular area of ​​the placement rack 3, the flange 7 can stop on the placement rack 3 to support the fertilizer box 5, and the fertilizer box 5 can be directly lifted and removed later. This detachable form of the fertilizer box 5 and the placement rack 3 is simple and easy to implement.

[0027] The fertilizer box 5 contains fertilizer for fertilization. The upper side of the fertilizer box 5 is opened to form a feeding port, and the bottom of the fertilizer box 5 is provided with a discharge port 6. Figure 4 As shown, in order to facilitate the automatic discharge of fertilizer, the fertilizer box 5 can be configured as a conical box with a larger top and a smaller bottom.

[0028] The lever discharging mechanism includes a material control rod 8, a connecting rope 9, a material baffle plate 10 and a spring 11. The material baffle plate 10 can slide back and forth at the material discharge port 6. A spring 11 is provided between the rear end of the material baffle plate 10 and the fertilizer box 5. The material control rod 8 can be installed on the frame 1 and rotated up and down and is adjacent to the handle 4. The front end of the material control rod 8 is connected to the rear end of the material baffle plate 10 by a connecting rope 9.

[0029] Therefore, when in use, the user can push the fertilizer trolley to move by the handle 4. During the movement, if fertilizer is needed, the control rod 8 can be pressed downward, and the front end of the control rod 8 is raised upward and the connecting rope 9 is pulled, and the connecting rope 9 then pulls the baffle plate 10 backward to slide, and the baffle plate 10 will compress the spring 11 and no longer block the discharge port 6, so that the fertilizer can fall from the discharge port 6 for fertilization. When the hand is released, the spring 11 will drive the baffle plate 10 to reset, block the discharge port 6 again, and stop fertilization.

[0030] In this process, the user can adjust the rotation angle of the control rod 8 by controlling the force of pressing the control rod 8, and then adjust the moving distance of the baffle plate 10, thereby adjusting the opening size of the discharge port 6 to achieve regulation of the fertilizer discharge amount.

[0031] In further settings, such as Figure 4 and Figure 5 As shown, a support seat 12 is provided at the bottom of the fertilizer box 5, and a slide groove 13 extending in the front-to-back direction is provided on the support seat 12, and the material blocking plate 10 is slidably matched with the slide groove 13, and the spring 11 is arranged in the slide groove 13, and the rear end of the spring 11 is fixedly connected to the support seat 12, and the front end is fixedly connected to the material blocking plate 10. Moreover, there are two support seats 12, one left and one right, and the material blocking plate 10 is arranged between the two support seats 12, and the left end of the material blocking plate 10 is matched with the slide groove 13 of the left support seat 12, and the right end is matched with the slide groove 13 of the right support seat 12, so that the material blocking plate 10 can be supported more stably.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the lever discharging mechanism also includes a fixed pulley 14 rotatably arranged on the frame 1, the fixed pulley 14 is located between the material control rod 8 and the material baffle plate 10, the front end of the connecting rope 9 is connected to the rear end of the material baffle plate 10, and the rear end passes around the fixed pulley 14 and then is connected to the front end of the material control rod 8 upward. The set fixed pulley 14 can change the rope laying direction of the connecting rope 9 to prevent the connecting rope 9 from being entangled on the wheel axle of the fertilizer cart and affecting the movement of the fertilizer cart.

[0033] In order to facilitate user control, Figure 3 As shown, the rotation center of the material control rod 8 is arranged near the front end of the material control rod 8. In this case, the material control rod 8 is a labor-saving lever, which is more convenient for users to press and operate.

[0034] In summary, the device is a purely mechanical structure with a simple overall structure and low manufacturing and processing cost. Moreover, after using the lever discharging mechanism, the user only needs to press the control rod 8 to adjust the fertilizer discharging situation at any time, which is very convenient to operate.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
