Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of irrigation equipment, in particular to a mobile irrigation equipment for crop plant protection. BACKGROUND

[0002] Plant protection is a discipline based on botany, zoology, microbiology, agricultural ecology and information science, which studies the occurrence and development of harmful organisms and proposes comprehensive control techniques. It is the medical science of the plant kingdom and an important part of crop production. It is one of the key measures to ensure the high yield and high quality of crops. Plant protection work includes disease and pest control and plant quarantine, which is the guarantee of crop harvest and the key measure to achieve high yield and pollution-free production. In order to economically and effectively protect plants, various control methods and active roles should be played to implement the principle of "prevention first and comprehensive control", so as to eliminate diseases, pests and other harmful organisms before they cause disaster and ensure safe production.

[0003] In plant protection work, the basic methods of plant protection generally include plant quarantine, agricultural control method, biological control method, chemical control method and physical and mechanical control method. The chemical control method is a control method that uses chemical pesticides to control crop diseases, pests and rodent pests, which is called chemical control or pesticide control. It has the advantages of wide control object, high control effect, fast speed, simple use method and small regional limitation. At present, it is still the key measure to control plant diseases and pests. In the process of chemical control, pesticide spraying and irrigation are an important means in the process of crop growth and development, and the mobile irrigation equipment refers to a sprinkling irrigation system whose power machine, water pump, dry pipe, branch pipe and spray head can be moved, which is convenient to use and is often used in plant protection work.

[0004] Leaves are the nutrient organs of most crops, and many crop diseases and pests have the habit of laying eggs on the back of crop leaves. After the larvae hatch from the eggs, they often drill into the leaf tissue and feed on the leaf tissue, causing the leaf chlorophyll to decompose and the sugar content in the leaf to decrease. When the damage is serious, the leaves of the damaged plants turn yellow and fall off, and even the seedlings die. In the prior art, when pesticides are sprayed and irrigated on crops, only the front of the crop leaves is usually irrigated, and the back of the crop leaves is missed, resulting in insufficient removal of diseases and pests on the back of the crop leaves. SUMMARY

[0005] The mobile irrigation equipment for crop plant protection provided by the embodiments of the present application can solve the problem that pesticides can only be sprayed and irrigated on the front of crop leaves in the prior art, and the removal of diseases and pests on the back of crop leaves is insufficient.

[0006] In order to solve the above technical problems, the present application adopts the following technical scheme: a mobile irrigation equipment for crop plant protection, comprising a plant protection vehicle, a liquid storage container, a water pump and a spray head, the liquid storage container is arranged on the plant protection vehicle, the water pump is connected with the liquid storage container at the liquid inlet end, the spray head is connected with the liquid outlet end of the water pump, and the mobile irrigation equipment further comprises: a gantry arranged on the plant protection vehicle; a swing plate rotatably connected to the inner side of the gantry, the front surface of the swing plate is provided with a liquid receiving groove, one end of the liquid receiving groove close to the gantry is provided with a drainage groove, the drainage groove is connected with a filter, the bottom of the drainage groove is provided with a return pipe connected with the liquid storage container, and the spray head is arranged at the end of the swing plate away from the gantry; a driving assembly connected with the swing plate, the driving assembly is used to drive the swing plate to make reciprocating swing movement in the vertical direction.

[0007] Preferably, the filter is a cylindrical structure with a closed end, a limiting ring is arranged on the filter, a tension spring is arranged between the limiting ring and the inner bottom wall of the drainage groove, the lower end of the filter is provided with a top rod penetrating out of the drainage groove, a baffle is arranged on the gantry, and the top rod is in contact with the baffle when the swing plate swings downward.

[0008] Specifically, the filter plays a role of filtering liquid medicine, so as to avoid impurities such as crop leaf or soil particles from mixing into the liquid medicine, and the filter will be blocked by impurities during use, which affects the filtering effect of the filter. Through the elastic connection of the filter and the drainage groove and the arrangement of the top rod and the baffle, when the swing plate swings downward, the lower end of the top rod gradually approaches and contacts the baffle, and then the baffle is pushed into the drainage groove, so that the limiting ring stretches the tension spring, the tension spring generates elastic potential energy, then the swing plate swings upward in the opposite direction, the lower end of the top rod is separated from the baffle, and the filter vibrates continuously under the action of the elastic potential energy of the tension spring, so that the impurities on the filter are shaken off, the filtering capacity of the filter is improved, the filtering efficiency of the liquid medicine is improved, and more liquid medicine is recovered. Preferably, a plurality of partitions are arranged in the liquid receiving groove.

[0009] Specifically, the partitions divide the liquid receiving groove into a plurality of flow grooves, so that the liquid medicine flows back and forth in the flow grooves with the swing of the swing plate, avoids the aggregation of the liquid medicine, and avoids the splashing of the liquid medicine to the outside due to the collision with the inner wall of the liquid receiving groove, thereby improving the recovery rate of the liquid medicine.

[0010] Preferably, one end of the partition towards the drainage groove is a slope structure.

[0011] Specifically, during the downward swing of the oscillating plate, any liquid that does not return to the storage container in time will flow towards the side where the nozzle is located. The advantage of setting the end of the baffle facing the flow channel as an inclined structure is that, during the flow of the liquid towards the side where the nozzle is located, the liquid will be evenly distributed inside each flow channel under the guiding effect of the inclined surface. This helps to avoid the liquid splashing caused by the collision between the liquid and the baffle, thereby improving the liquid recovery rate.

[0012] Preferably, the upper part of the gantry is provided with a baffle, and the lower end surface of the baffle is an inclined flow guiding structure.

[0013] Specifically, the liquid sprayed high by the nozzle will accumulate under the obstruction of the baffle. The accumulated liquid will flow to the receiving tank under the guidance of the lower end of the baffle. After being filtered by the filter, it will enter the diversion tank and then flow back to the storage container for reuse through the return pipe, thereby improving the liquid recovery rate.

[0014] Preferably, the drive assembly includes a drive unit fixedly connected to the gantry frame. The drive unit is an engine or an electric motor. The output end of the drive unit is provided with a drive rod. The drive rod is hinged to a connecting rod. The connecting rod is hinged to a slide rod that is vertically slidably connected to the gantry frame. The lower end of the slide rod is provided with a drive block. The drive block is provided with a drive groove. The swing plate is provided with a long rod that extends into the drive groove.

[0015] Specifically, the drive unit drives the drive rod to rotate, and the drive rod drives the slide rod and drive block to reciprocate linearly in the vertical direction through the connecting rod. The drive groove on the drive block drives the swing plate to reciprocate in the vertical direction through the long rod, so that the liquid sprayed from the nozzle can spray and irrigate the front and back of the crops.

[0016] Compared to existing technologies, this invention utilizes a coordinated setup of a plant protection vehicle, a storage container, a water pump, nozzles, a gantry frame, a swing plate, a receiving trough, a drainage trough, a filter, a return pipe, and a drive assembly. The plant protection vehicle moves between rows of crops, the water pump draws pesticide from the storage container and delivers it to the nozzles, and the drive assembly drives the swing plate to reciprocate vertically. During upward swinging, the swing plate generates an upward airflow, causing the back of the crop leaves to face the nozzles, which then spray the pesticide onto the back of the leaves. During downward swinging, the swing plate generates a downward airflow, causing the front of the crop leaves to face the nozzles, which then spray the pesticide onto the front of the leaves. The reciprocating motion of the nozzles increases the spraying area, ensuring the pesticide covers the entire crop plant, spraying and irrigating both the front and back of all leaves, thus improving the effectiveness in controlling crop diseases and pests.

[0017] Compared with the prior art, in the process of upward swinging of the spray head, part of the liquid sprayed on the crops falls under the action of gravity and is collected by the liquid receiving groove, the collected liquid flows to the drainage groove under the action of gravity along with the upward swinging of the spray head, is filtered by the filter, and is returned to the liquid storage container through the return pipe for secondary use, liquid is saved, waste is reduced, and environmental pollution is reduced.

A swing plate 6 is pivotally connected to the inner side of the gantry 5, and a liquid receiving groove 7 is formed on the front side of the swing plate 6. The liquid receiving groove 7 is provided with a drainage groove 8 at one end close to the gantry 5, and a filter 10 is connected to the drainage groove 8. The bottom of the drainage groove 8 is provided with a return pipe 9 connected to the liquid storage container 2. The spray head 4 is arranged at the end of the swing plate 6 away from the gantry 5. A driving assembly is connected to the swing plate 6 and used to drive the swing plate 6 to make reciprocating swing movement in the vertical direction.

[0022] In use, the plant protection vehicle 1 moves between the rows of crops. The water pump 3 draws the pesticide liquid in the liquid storage container 2 and delivers the pesticide liquid to the spray head 4. The driving assembly drives the swing plate 6 to make reciprocating swing movement in the vertical direction. During the upward swing of the swing plate 6, the swing plate 6 generates upward wind force, so that the back of the crop leaves faces the spray head 4, and the spray head 4 sprays the pesticide liquid on the back of the crop leaves. During the downward swing of the swing plate 6, the swing plate 6 generates downward wind force, so that the front of the crop leaves faces the spray head 4, and the spray head 4 sprays the pesticide liquid on the front of the crop leaves. The reciprocating spray head 4 increases the spraying area, so that the pesticide liquid covers the entire crop plant, and sprays and irrigates the front and back of all the crop leaves. The part of the pesticide liquid not sprayed on the crops falls under the action of gravity and is collected by the liquid receiving groove 7. The collected pesticide liquid flows to the drainage groove 8 under the action of gravity when the spray head 4 swings upward, is filtered by the filter 10, and is returned to the liquid storage container 2 by the return pipe 9 for secondary use.

When the swing plate 6 swings downward, the top rod 11 contacts the baffle 12.

[0024] Specifically, the filter 10 plays a role of filtering the liquid medicine, so as to avoid impurities such as crop leaves or soil particles from mixing into the liquid medicine. During use, the filter 10 will be blocked by the impurities, which affects the filtering effect of the filter 10. Through the elastic connection of the filter 10 and the drainage groove 8 and the arrangement of the top rod 11 and the baffle 12, when the swing plate 6 swings downward, the lower end of the top rod 11 gradually approaches and contacts the baffle 12, and then is pushed into the drainage groove 8 by the baffle 12, so that the limiting ring 22 stretches the tension spring 23, and the tension spring 23 generates elastic potential energy. Then, the swing plate 6 swings upward in the opposite direction, the lower end of the top rod 11 is separated from the baffle 12, and the filter 10 is vibrated under the action of the elastic potential energy of the tension spring 23, so as to shake off the impurities on the filter 10, improve the filtering capacity of the filter 10, improve the filtering efficiency of the liquid medicine, and recover more liquid medicine.
