Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0026] For example 1, please refer to Figure 1 , soybean and corn strip composite planting plant protection equipment, including a vehicle body 1, a carrier plate 2 is fixedly installed at the front end of the vehicle body 1, a medicine box 3 is fixedly installed on the top of the carrier plate 2, a support plate 25 is fixedly connected to the bottom of the carrier plate 2, a water pump 26 is fixedly installed on the top of the support plate 25, the input end of the water pump 26 is connected to the inner cavity of the medicine box 3 by a water supply pipe, and two limiting plates 4 are fixedly connected to the top of the carrier plate 2. The two limiting plates 4 are both located on one side of the front end of the medicine box 3. Please refer to Figure 2-Figure 4The top of the limiting frame 7 is provided with a driving motor, and the driving motor drives the rotating column 8 to rotate, so that the spray boom arm can be controlled to rotate ninety degrees when the plant protection equipment is not in use, so as to avoid the spray boom arm affecting the normal driving of the plant protection equipment on the road.
[0027] See also Figure 3-Figure 5 The boom mechanism includes a positioning coupling 11 fixedly connected to the lower arm 10. The bottom end of the positioning coupling 11 is fixedly connected to the main nozzle 12. The side of the main nozzle 12 is fixedly connected to a plurality of rotary joints 14, and the plurality of rotary joints 14 are equidistantly arranged on the main nozzle 12. The number of rotary joints 14 is not less than two. The rotating pipe end of the rotary joint 14 is fixedly connected to a longitudinal guide tube 15. The bottom end of the longitudinal guide tube 15 is fixedly connected to a nozzle 16. Please refer to Figure 1-Figure 3 , two limit wires 17 are fixedly connected between each two longitudinal conduits 15, and the two limit wires 17 are respectively arranged at the top and bottom of the longitudinal conduits 15, and one end of the two limit wires 17 is fixedly connected to a limit plate 4 on the side away from the medicine box 3, please refer to Figure 2 and Figure 6 A water pipe 13 is fixedly connected between each two main nozzles 12. Figure 2 and Figure 4 The innermost main nozzle 12 is connected to the output pipe of the water pump 26.
[0028] The longitudinal conduit 15 is connected to the main nozzle 12 through a water pipe 13, and the upper and lower ends of the longitudinal conduit 15 are fixedly connected with a limit wire 17, so that each longitudinal conduit 15 is limited by the limit wire 17. When the spray boom arm swings due to the bumps of the vehicle body 1, it can ensure that the nozzle of the nozzle 16 at the bottom end of the longitudinal conduit 15 is always facing directly downward, thereby ensuring the spraying effect on the plants, avoiding the problem of the existing spray boom sprayer that when the spray boom arm is in use, the spray boom arm is easily shaken by the bumps of the vehicle body 1 when moving, causing the nozzle 16 fixed on the bracket to swing, thereby affecting the spraying effect on the plants.
[0029] See also Figure 2-Figure 4The top end of the positioning coupling 11 passes through the lower arm 10 and is fixedly connected to the bottom of the upper arm 9. While the main nozzle 12 is connected by the positioning coupling 11, the upper arm 9 and the lower arm 10 are also connected through the positioning coupling 11, thereby improving the overall strength of the spray boom arm.
[0030] Please continue to see 2- Figure 4 The top and bottom ends of the pendulum block 6 are rotatably connected to a group of connecting rods 18, each group of connecting rods 18 has two connecting rods 18, and the two connecting rods 18 are respectively arranged on both sides of the pendulum block 6. The end of each group of connecting rods 18 away from the pendulum block 6 is rotatably connected to a linkage block 19, and one end of the linkage block 19 is fixedly connected to a sliding shaft 20. The end of the sliding shaft 20 away from the linkage block 19 is movably sleeved with a baffle 22, and one end of the sliding shaft 20 is threaded with a bolt, which limits the baffle 22 to prevent the baffle 22 from falling off. A positioning plate 23 is movably sleeved on the two sliding shafts 20, and the positioning plate The two sides of 23 are fixedly connected to the inner side walls of the two limiting plates 4 respectively. A spring 21 that is movably mounted on the slide shaft 20 is provided between the baffle 22 and the positioning plate 23. The spring 21 is normally in a relaxed state. A gap is reserved between the bottom of the pendulum block 6 and the top of the carrier plate 2. Under normal circumstances, the support of the positioning shaft 5 and the elastic pulling effect of the two sets of springs 21 keep the spray boom arm in a horizontal state. During spraying, when the vehicle body 1 is traveling and bumpy, the spray boom arm, the rotating column 8, the limiting frame 7, and the pendulum block 6 rotate as a whole around the positioning shaft 5. For details, please refer to Figure 4 That is, when the boom arm moves downward away from one end of the positioning shaft 5, the connecting rod 18 at the upper end of the pendulum block 6 will pull the sliding shaft 20 to the left, thereby compressing the spring 21, and utilizing the restoring force of the spring 21 when compressed to perform buffering and reset, while the connecting rod 18 at the lower end of the pendulum block 6 pushes the other set of sliding shafts 20 to move right, thereby another tension spring 21, and utilizing the restoring force of the spring 21 when stretched to perform buffering and reset, thereby further improving the anti-bumping ability of the boom arm and improving the stability of the boom arm. In addition, the structural design of the boom arm being rotatably connected relative to the positioning shaft 5, while ensuring that the boom arm can always remain in a horizontal state, also avoids the problem that the boom arm of the existing boom sprayer adopts a fixed connection method, which is easy to cause the fixed part to fall off due to the frequent swinging of the boom arm when the vehicle body 1 is driving.
[0031] When the soybean-corn strip composite planting plant protection equipment is in use, the driving motor first drives the rotating column 8 to rotate, so that the rotating column 8 drives the spray arms on both sides of the vehicle body 1 to rotate out, and then the pneumatic vehicle body 1 moves in the gaps between the plants to be sprayed. At the same time, the water pump 26 pumps the medicine in the medicine box 3 into the main nozzles 12 on both sides, so that the medicine is sprayed from each nozzle 16 to spray the plants. During the movement of the vehicle body 1, when the spray arm swings, the pulling force and pressure of the two sets of springs 21 are used for buffering, so as to effectively protect the connection structure of the spray arm, and the upper and lower ends of each longitudinal guide tube 15 are pulled by two limiting wires 17, and a rotary joint 14 is set between the longitudinal guide tube 15 and the main nozzle 12, so that the nozzle of the nozzle 16 at the bottom end of the longitudinal guide tube 15 always sprays toward the plants below.
[0032] For example 2, please refer to Figure 7 , different from the first embodiment, the medicine box 3 includes a soybean medicine box 301 and a corn medicine box 302, and the soybean medicine box 301 and the corn medicine box 302 are independent of each other, the water pump 26 includes a first water pump 261 and a second water pump 262, and the water suction port of the first water pump 261 is connected to the inner cavity of the soybean medicine box 301, and the water suction port of the second water pump 262 is connected to the inner cavity of the corn medicine box 302, the water outlet of the first water pump 261 is connected to two first conduits 2611, and the two first conduits 2611 extend to the two spray boom walls on both sides of the medicine box respectively, the water outlet of the second water pump 262 is connected to two second conduits 2621, the main nozzle 12 includes a soybean spray main pipe 121 and a corn spray main pipe 122, and the soybean spray main pipe 121 and the corn spray main pipe 122 are connected to the spray boom wall. The bottom is arranged in an alternating manner from the inside to the outside. A glass partition 27 is provided between the soybean spray main pipe 121 and the corn spray main pipe 122, and the top of the glass partition 27 is fixedly connected to the spray boom wall. A first positioning pipe 2612 is connected between the soybean spray main pipe 121 and the first pipe 2611, and the first positioning pipe 2612 is fixedly socketed with the lower arm 10. A second positioning pipe 2622 is connected between the corn spray main pipe 122 and the second pipe 2621, and the second positioning pipe 2622 is fixedly socketed with the lower arm 10. A fixing block 28 is connected between the first pipe 2611 and the second pipe 2621 and the spray boom wall respectively. The two pipes can be stably fixed on the spray boom wall through the fixing block 28, and both pipes are hoses, which will not affect the rotation and recovery of the spray boom wall.
[0033] By setting up a soybean medicine box 301 and a corn medicine box 302 separately, and pumping the liquid medicine in the two medicine boxes respectively through the first pump body 261 and the second pump body 262, independent control of soybean and corn belt spraying can be achieved, and by setting a glass partition 27 between the soybean spraying main pipe 121 and the corn spraying main pipe 122, when soybean and corn belts are sprayed at the same time, the different medicines applied by the two will not affect each other.
