Description

Technical Field

[0001] This utility model belongs to the technical field of water and fertilizer applicators, and in particular relates to a tobacco fertilizer applicator. Background Technology

[0002] In tobacco cultivation, traditional fertilization methods rely on manual operation. Specifically, a water pipe is directly connected to a scoop head, and an operator moves the fertilizer to each tobacco seedling planting location. Simultaneously, another person uses a vehicle to drag a bucket containing fertilizer along with the plant. This method requires the operator to hold the pipe and move the scoop head for extended periods, resulting in high labor intensity and low efficiency. Furthermore, the need for two people working together leads to high labor costs. In addition, the dragged pipe is prone to rubbing against the tobacco seedlings, causing damage or lodging, thus affecting crop growth and yield. To address these problems, this application provides a tobacco fertilizer applicator.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0030] Please see Figure 1-7 As shown, this utility model is a tobacco fertilizer applicator, specifically designed for applying biogas slurry organic fertilizer after transplanting tobacco seedlings onto ridges. The fertilizer applicator includes a mobile carrier 1, a water and fertilizer tank 2, a mobile power supply 3, and two sets of fertilizer application components mounted on the mobile carrier 1.

[0031] The water-fertilizer tank 2 has a rectangular box structure and is used to hold biogas slurry organic fertilizer. Two output pipes 21 are located on one side of the bottom of the tank 2. Each output pipe 21 is equipped with a solenoid valve 22 to control the flow of biogas slurry. A threaded round cover 23 is located at the top of the tank 2 for easy addition of biogas slurry and internal cleaning. A right-angle plate 111 is fixed at each of the four corners of the platform plate 12 to limit the movement of the tank 2.

[0032] The fertilization assembly includes a fertilization pipe 4, an adjustable clamp 5, a connecting pipe 6, and two control switches 7 for controlling two solenoid valves 22 in the pipeline. The fertilization pipe 4 is connected to the output pipe 21 via the connecting pipe 6. The fertilization pipe 4 includes a connecting pipe section 41 that connects to the connecting pipe 6. The lower end of the connecting pipe section 41 is provided with an expansion section 42 to expand the spraying range of the biogas slurry and improve fertilization efficiency.

[0033] Pressing the control switch 7 controls the solenoid valve 22 on the output pipe 21 to switch between opening and closing. When the mobile carrier 1 carrying the fertilizer pipe 4 arrives at the tobacco seedling cultivation position, pressing the corresponding control switch 7 opens the channel of the solenoid valve 22 to output water and fertilizer from the water and fertilizer tank 2. After the output water and fertilizer amount is sufficient, pressing the control switch 7 again controls the solenoid valve 22 on the output pipe 21 to close.

[0034] The mobile carrier 1 includes a platform frame 11. A platform plate 12 is fixed to the top surface of the platform frame 11. A water and fertilizer tank 2 is installed on the platform plate 12. An L-shaped frame 13 is fixed to the middle of the rear end of the platform frame 11. A secondary plate 14 is fixed to the top surface of the horizontal plate of the L-shaped frame 13. A shaft 15 is installed on the lower surface of the platform frame 11 via two bearings with seats. A wheel 16 is installed at each end of the shaft 15 to facilitate the movement of the fertilizer applicator between rows. A self-locking caster wheel 17 is installed on the lower surface of the secondary plate 14 to enhance the flexibility and stability of the fertilizer applicator. A column rod 18 is fixed to the upper surface of the secondary plate 14. Two handles 19 are symmetrically fixed to the upper end of the column rod 18. Two control switches 7 are installed on the two handles 19 respectively to facilitate the operator to control the fertilization process. A battery box 110 for placing a mobile power supply 3 is fixed on the secondary plate 14 to provide power to the pipeline solenoid valve 22.

[0035] When the water and fertilizer tank 2 is not pressurized, the round cover 23 should be in the open or half-turned position during fertilization to ensure ventilation of the water and fertilizer tank 2. The adjustable clamp 5 is used to fix the fertilizer pipe 4, and it includes a U-shaped plate 51. A sleeve 52 that mates with the connecting pipe section 41 is fixed to the closed end of the U-shaped plate 51. A bolt with a handle 53 is threaded through the sleeve 52 to tighten the fertilizer pipe 4. Two round through holes 54 are opened on the two walls of the U-shaped plate 51. Rectangular strips 112 are symmetrically fixed on both sides of the L-shaped frame 13 at the rear end of the platform frame 11. The rectangular strips 112 are provided with oval through holes 113. The U-shaped plate 51 is inserted into the rectangular strips 112 and fixed by two sets of bolts and nuts, so that the position of the adjustable clamp 5 on the platform frame 11 is adjustable, thereby accurately adjusting the fertilization position of the fertilizer pipe 4 near the tobacco seedlings on the ridge.

[0036] A specific application of this embodiment is as follows: In practical application, the operator first pours the biogas slurry organic fertilizer into the water-fertilizer tank 2 and screws on the round cap 23. Then, by using the handle 19, the operator pushes the fertilizer applicator to the ridge where the tobacco seedlings are located, and adjusts the position of the adjustable clamp 5 according to the position of the tobacco seedlings, so that the expansion section 42 of the fertilizer pipe 4 is aligned with the side of the tobacco seedling roots. When the fertilizer applicator reaches the fertilization position, the operator presses the control switch 7 corresponding to the fertilizer pipe 4, opens the pipeline solenoid valve 22, and the biogas slurry organic fertilizer flows out through the output pipe 21, connecting pipe 6 and fertilizer pipe 4, and is applied to the roots of the tobacco seedlings. When the biogas slurry outflow reaches the required amount, the operator presses the control switch 7 again to close the pipeline solenoid valve 22, completing one fertilization process.

[0037] In addition, to ensure stable air pressure within the water-fertilizer tank 2 during fertilization, an air pump can be installed on the tank. The aforementioned portable power supply 3 provides power to the air pump, which is connected to the water-fertilizer tank 2 via an air duct. During fertilization, the air pump pressurizes the tank, ensuring a stable output of biogas slurry organic fertilizer. Simultaneously, a pressure switch is installed on the water-fertilizer tank 2. When the air pressure inside the tank reaches the set value, the air pump automatically stops working, preventing damage to the tank or splashing of biogas slurry due to excessive pressure. When using the air pump for pressurization, the round cover 23 on the water-fertilizer tank 2 must be tightened.
