Description

Technical Field

[0001] The present application relates to the field of agricultural machinery, and in particular to a plant protection machine. Background Art

[0002] Plant protection machines play a vital role in modern agricultural production. By mechanizing the application of pesticides and fertilizers, they not only significantly improve agricultural production efficiency but also effectively reduce labor costs. With the continuous development of agricultural technology, the design of plant protection machines has also been gradually improved, gradually becoming an indispensable and important equipment in modern agricultural production.

[0003] Plant protection machines have been widely used in the planting and management of various crops. The improvement of their functions and performance is of great significance to promoting the process of agricultural modernization.

[0004] In related technologies, most plant protection machines have relatively single functions and are usually only used to spray pesticides or nutrient solutions. As agricultural technology is constantly iterating today, single-function plant protection machines are difficult to adapt to the requirements of current agricultural technology development. Summary of the Invention

[0005] In order to improve the functionality of a plant protection machine, the present application provides a plant protection machine.

[0006] The plant protection machine provided in this application adopts the following technical solution: A plant protection machine comprises a vehicle body, a medicine liquid tank and a fertilizer tank are mounted on the upper end of the vehicle body, the front end of the vehicle body is fixedly connected to a main spraying rod, both ends of the main spraying rod are rotatably connected to folding spraying rods, the main spraying rod and the folding spraying rod are mounted with the same spraying pipe, an atomizing nozzle is mounted on the spraying pipe, an infusion pipe is fixed between the spraying pipe and the medicine liquid tank and connected, a pump body is mounted on the infusion pipe, the lower end of the fertilizer tank is fixedly connected to and connected with a discharge pipe, a control valve is mounted on the discharge pipe, a plurality of discharge pipes are arranged below the discharge pipe, a feeding mechanism for connecting the plurality of discharge pipes and the fertilizer tank is provided between the two, and a stirring assembly for stirring the fertilizer in the fertilizer tank is provided in the fertilizer tank.

[0007] By adopting the above technical solution, a liquid medicine tank and a fertilizer tank are installed on the vehicle body, which are used to store liquid medicine and fertilizer respectively, and the functional areas are clearly divided. The design of the main spraying rod and the folding spraying rod makes the spraying range adjustable to adapt to different farmland environments. The atomizing nozzle on the spraying pipe can spray the liquid medicine evenly on the crops, improving the utilization rate of the medicine. The infusion pipe cooperates with the pump body to achieve stable delivery of the liquid medicine. The discharge pipe and the control valve control the output of the fertilizer. The multiple feed pipes cooperate with the cloth mechanism to ensure that the fertilizer is evenly distributed in the field. At the same time, the stirring assembly stirs the fertilizer to prevent the fertilizer from settling and ensure the fertilization effect. Therefore, the plant protection machine in this application can spray liquid medicine and fertilizer at the same time, and according to actual conditions, the fertilizer can also be replaced with seeds or a mixture of seeds and fertilizer, thereby not only improving the efficiency of agricultural operations but also improving the functionality of the plant protection machine.

[0008] Optionally, the distribution mechanism includes a distribution shell fixedly connected to and connected to the lower end of the fertilizer box, a plurality of partition plates are fixedly connected inside the distribution shell, and the distance between two adjacent partition plates is the same. The partition plates divide the distribution shell into a plurality of discharge channels, and the discharge channels correspond to the discharge pipes one by one and are fixedly connected. The distribution shell is provided with a blocking component for blocking the discharge channels.

[0009] By employing this technical solution, the distribution mechanism divides the fertilizer box's outlet into multiple independent delivery channels, each connected to a corresponding delivery pipe, ensuring even distribution of fertilizer. The design of the divider ensures uniform spacing between the delivery channels, further ensuring uniform fertilizer distribution. The blocking assembly provides flexible control over the delivery channels, facilitating adjustment of fertilizer drop location and distribution density based on actual field ridge requirements.

[0010] Optionally, the blocking assembly includes a plurality of blocking plates, each of which corresponds to the discharge channel one by one, and the blocking plates are slidably inserted into the feed end of the discharge channel, and the blocking plates are threadedly connected with fixing bolts, and the fixing bolts are threadedly connected to the cloth shell.

[0011] By adopting this technical solution, the blocking plates correspond one-to-one with the feed channels, enabling precise and independent blocking and opening of each channel, improving the flexibility and controllability of the distribution mechanism. The sliding plug-in design facilitates installation and removal of the blocking plates, simplifying the operation process. The fixing bolts secure the blocking plates to the feed housing, ensuring the stability of the blocking state and preventing failure due to vibration during operation of the plant protection machine, thereby maintaining accurate fertilizer distribution.

[0012] Optionally, the discharge pipe is configured as a rubber hose.

[0013] By adopting the above technical solution, setting the discharge pipe as a rubber hose can enhance the flexibility of the discharge pipe, so that it can better adapt to the requirements of different terrains, vegetation and angles during use, and reduce the risk of damage.

[0014] Optionally, a metal protection tube is sleeved on the outer wall of the discharge tube, one end of the metal protection tube is fixedly connected to the lower end side wall of the cloth shell, and the metal protection tube includes two metal joint tubes rotatably connected together.

[0015] By adopting the above technical solution, the metal protective tube can effectively protect the feed pipe from damage caused by the external environment, thereby extending the service life of the feed pipe. The metal protective tube is composed of two rotatably connected metal tube sections, which allows the metal protective tube to rotate freely when facing terrain and vegetation, providing good support and protection for the feed pipe.

[0016] Optionally, the discharge end of the discharge pipe is fixedly connected to and communicated with multiple distribution pipes.

[0017] By adopting the above technical solution, the design of the distribution pipe can increase the fertilizer distribution range and optimize the quality of the fertilization operation.

[0018] Optionally, the cloth shell is provided with a dredging component for dredging the discharge end of the discharge pipe and the connection between the discharge channel and the discharge pipe.

[0019] By adopting the above technical solution, the dredging component can reduce the occurrence of blockage at the discharge end of the discharge pipe and the connection between the discharge channel and the discharge pipe.

[0020] The air filter press of described outer combustion gas heating unit is connected with the air filter press of described outer combustion gas heating unit, and the air filter press of described outer combustion gas heating unit is connected with the air filter press of described outer combustion gas heating unit.

[0021] By adopting the above technical solution, the high-pressure airflow generated by the high-pressure air pump is transmitted to each cleaning bin through the main output pipe and the branch output pipe. When the airflow passes through the cleaning bin, the branch output pipe will expand, and the cleaning bevel in the cleaning bin will overcome the tension of the spring and move under the impact of the expansion of the airflow in the branch output pipe, thereby clearing the connection between the discharge channel and the discharge pipe.

[0022] When the airflow stops, the spring resets the cleaning ramp, keeping the connection between the discharge channel and the discharge pipe unobstructed. This improves the smoothness of fertilizer delivery and reduces maintenance costs. The airflow in the branch output pipe further moves to the discharge end of the discharge pipe, clearing any waste material clogged there. The discharge pipe is made of rubber and has a metal joint on the outside. If the discharge pipe becomes severely clogged, the discharge end expands. The metal joint limits expansion at other locations, applying a momentary impact force to the connection between the discharge channel and the discharge pipe, making it easier to clear fertilizer clogged in these two locations.

[0023] Optionally, the stirring assembly includes a stirring motor installed on the fertilizer box, a stirring rod is provided in the fertilizer box, and an output shaft of the stirring motor is fixedly connected to the stirring rod.

[0024] By adopting the above technical solution, the mixing motor drives the stirring rod to stir the fertilizer in the fertilizer box, which can effectively prevent the fertilizer from agglomerating during storage, ensure the fertilizer is evenly distributed, and thus improve the fertilizer application effect.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By installing a liquid pesticide tank and a fertilizer tank on the vehicle body, combined with the structural design of the main spraying boom, folding spraying boom and spraying pipe, the simultaneous application of pesticides and fertilizers is achieved, significantly improving operation efficiency and coverage; 2. The feeding mechanism evenly distributes fertilizer to multiple feeding pipes, effectively solving the problem of uneven fertilizer distribution and ensuring the accuracy and uniformity of fertilization; 3. The stirring component stirs the fertilizer in the fertilizer box to prevent the fertilizer from clumping, avoids the blockage of the feed pipe caused by clumping, and improves the stability and reliability of the equipment.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0029] The embodiment of the present application is: a plant protection machine, referring to Figure 1 and Figure 2 The vehicle comprises a vehicle body 1, which is an agricultural vehicle body 1 in the prior art. A liquid medicine tank 2 is mounted on the upper end of the vehicle body 1. A main spraying rod 4 is fixedly connected to the front end of the vehicle body 1. Both ends of the main spraying rod 4 are rotatably connected to folding spraying rods 5, which can be unfolded. The main spraying rod 4 and the folding spraying rod 5 are mounted with the same spraying pipe 6, which is equipped with an atomizing nozzle 61. A liquid infusion pipe 7 is fixed between the spraying pipe 6 and the liquid medicine tank 2 and is connected to the liquid medicine tank 2. The liquid infusion pipe 7 is equipped with a pump body 71 for transporting the liquid medicine in the liquid medicine tank 2 to the spraying pipe 6.

[0030] Thus, the pump body 71 can be started to transport the liquid medicine into the spray pipe 6 through the pump body 71 , and then the liquid medicine is sprayed through the atomizing nozzle 61 .

[0031] Reference Figure 1 、 Figure 3 and Figure 4 A rectangular parallelepiped fertilizer tank 3 is mounted on the upper end of the vehicle body 1. A discharge pipe 8 is fixedly connected to the lower end of the fertilizer tank 3 and communicates with the discharge pipe 8. A control valve 81 is mounted on the discharge pipe 8. When the control valve 81 is opened, waste material in the fertilizer tank 3 passes under the discharge pipe 8. To facilitate the flow of fertilizer, a stirring assembly 11 is provided within the fertilizer tank 3 for agitating the fertilizer within.

[0032] The stirring assembly 11 includes a stirring motor 112 mounted on the upper end of the fertilizer box 3. A stirring rod 111 is provided in the fertilizer box 3 and extends along the length of the fertilizer box 3. The output shaft of the stirring motor 112 is fixedly connected to the stirring rod 111. When the stirring motor 112 is started, the stirring motor 112 drives the stirring rod 111 to rotate, thereby stirring the material in the fertilizer box 3.

[0033] A plurality of discharge pipes 10 are provided below the discharge pipe 8. A distribution mechanism 9 is provided between the plurality of discharge pipes 10 and the fertilizer housing 3 to connect the two. The distribution mechanism 9 includes a distribution housing 91 fixedly connected to and in communication with the lower end of the fertilizer housing 3. The distribution housing 91 is configured as a rectangle that is narrow at the top and wide at the bottom. A plurality of partition plates 92 are fixedly connected to the distribution housing 91. Adjacent partition plates 92 are spaced the same distance apart. The partition plates 92 divide the distribution housing 91 into a plurality of discharge channels 93. The discharge channels 93 correspond to and are fixedly connected to the discharge pipes 10 one by one. The distribution housing 91 is provided with a blocking assembly 94 for blocking the discharge channels 93.

[0034] The blocking assembly 94 includes a plurality of blocking plates 941, which are located on the upper portion of the material distribution housing 91 and correspond one to one with the material distribution channel 93. The blocking plates 941 are slidably inserted into the inlet end of the material distribution channel 93 and completely block the upper portion of the material distribution channel 93. Two fixing bolts 942 are threadedly connected to the blocking plates 941, and the threaded rods of the fixing bolts 942 are connected to the material distribution housing 91. By rotating the fixing bolts 942, the rods of the fixing bolts 942 are separated from the material distribution housing 91, and the blocking of the material distribution channel 93 by the blocking plates 941 can be cancelled.

[0035] Thus, by opening the control valve 81, the fertilizer in the fertilizer box 3 can be discharged from the discharge pipe 8 into the distribution housing 91. The fertilizer will then enter the various discharge pipes 10 through the discharge channel 93 for discharge. At the same time, in order to reduce the possibility of the discharge pipe 10 being knocked and affected by the discharge, the discharge pipe 10 is configured as a rubber hose. A metal protective tube 12 is sleeved on the outer wall of the discharge pipe 10. One end of the metal protective tube 12 is fixedly connected to the lower end side wall of the distribution housing 91. The metal protective tube 12 includes two rotatably connected metal joint tubes 121. The discharge pipe 10 is placed in the two metal joint tubes 121. At the same time, in order to increase the discharge area of ​​the discharge pipe 10, the discharge end of the discharge pipe 10 is fixedly connected and connected to multiple distribution pipes 13. In this embodiment, there are two distribution pipes 13.

[0036] Reference Figure 3 、 Figure 4 and Figure 5The material distribution housing 91 is provided with a dredging assembly 14 for dredging the discharge end of the material distribution pipe 10 and the connection between the material distribution channel 93 and the material distribution pipe 10. The dredging assembly 14 includes a high-pressure air pump 141 mounted on the material distribution housing 91. In this embodiment, two high-pressure air pumps 141 are provided, one on each side of the material distribution housing 91. A main output pipe 142 is fixedly connected to the high-pressure air pump 141, and multiple branch output pipes 143 are fixedly connected to the main output pipe 142. Each branch output pipe 143 is equipped with an air valve 144.

[0037] A mounting tube 145 is installed at the lower end of the cloth shell 91, and a plurality of cleaning bins 146 are provided in the mounting tube 145. The cleaning bins 146 correspond to and are connected with the discharge channel 93 one by one. The cleaning bin 146 is located at the connection between the discharge channel 93 and the discharge pipe 10. A cleaning inclined block 147 is slidably connected in the cleaning bin 146. The side of the cleaning inclined block 147 close to the cloth shell 91 is set as an inclined surface, and a spring 148 is fixedly connected between the cleaning inclined block 147 and the inner wall of the cleaning bin 146 away from the cloth shell 91. In this embodiment, there are two springs 148 and they are respectively located on both sides of the cleaning inclined block 147. The branch output pipe 143 is passed through and fixedly connected to the cleaning bin 146. The branch output pipe 143 is set as a hose. Under the action of the spring 148, the cleaning inclined block 147 is pressed tightly on the branch output pipe 143.

[0038] The branch output pipe 143 corresponds to the cleaning chamber 146 one by one. The branch output pipe 143 is placed between the cleaning bevel 147 and the inner wall of the cleaning chamber 146, and the spring 148 compresses this part of the branch output pipe 143. The output end of the branch output pipe 143 is fixed and connected to the discharge end of the discharge pipe 10.

[0039] Then, by starting the high-pressure pump body 71, the high-pressure airflow generated by the high-pressure air pump 141 is transmitted to each cleaning chamber 146 through the main output pipe 142 and the branch output pipe 143. When the airflow passes through the cleaning chamber 146, the branch output pipe 143 will expand. Under the impact of the airflow expansion in the branch output pipe 143, the cleaning bevel 147 in the cleaning chamber 146 will move to overcome the tension of the spring 148, thereby clearing the connection between the discharge channel 93 and the discharge pipe 10. The airflow in the branch output pipe 143 will further move to the discharge end of the discharge pipe 10, clearing the waste material blocked at the discharge end of the discharge pipe 10. At the same time, the discharge pipe 10 is made of rubber and has a metal joint pipe 121 on its exterior. When the discharge pipe 8 is seriously blocked, the discharge end of the discharge pipe 10 will expand. The metal joint pipe 121 will limit the expansion of other parts of the discharge pipe 10, and at the same time, it will apply an instantaneous impact force to the connection between the discharge channel 93 and the discharge pipe 10. And then the fertilizer that is blocked in above-mentioned two places is dredged.When airflow stops subsequently, cleaning inclined block 147 is reset under the effect of spring 148, and the junction of feed channel 93 and feed pipe 10 is kept unimpeded.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
