Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a track docking mechanism and a spraying device. Background Technology

[0002] During greenhouse cultivation, it is necessary to spray liquid onto the crops grown inside the greenhouse. Currently, the main method is to install a track on the top of the greenhouse, and then install a spraying device on the track to spray the liquid.

[0042] This utility model provides a track docking mechanism and spraying device that improves work efficiency and reduces safety hazards.

[0043] The following is combined with Figures 1 to 7 The technical solution provided by this utility model will be described in more detail.

[0044] This utility model provides a track docking mechanism 300, including a lifting component and a positioning component 310. The lifting component is connected to a movable track 220 to drive the movable track 220 to move up and down.

[0045] The positioning component 310 is disposed on the moving path of the movable track 220 to position the movable track 220 so that the movable track 220 docks with the fixed track 210.

[0046] The track docking mechanism 300 provided by this utility model includes a lifting component and a positioning component 310. The lifting component is used to drive the movable track 220 to move up and down. The positioning component 310 is set on the movement path of the movable track 220 to position the movable track 220 so that the movable track 220 docks with the fixed track 210. This allows the spraying device to be lowered to a suitable height by lifting the movable track 220 to complete the liquid replenishment, greatly improving the liquid replenishment efficiency and thus improving the efficiency of greenhouse planting. After the liquid replenishment is completed, the movable track 220 and the spraying device are raised again so that the movable track 220 docks with the fixed track 210 to continue spraying. The entire liquid replenishment process can be completed at a suitable height without the need for a ladder, greatly reducing safety hazards.

[0047] It is understood that the positioning component 310 is designed to precisely position the movable track 220 when the lifting component drives the movable track 220 to move upward, thereby ensuring that the movable track 220 and the fixed track 210 are precisely aligned, so that the spraying device can complete the spraying along the conveying track 200 and realize the liquid spraying of crops in the greenhouse.

[0048] It should be noted that the liquid sprayed by the spraying device can be water, pesticides, liquid fertilizers, or other liquids suitable for greenhouse cultivation.

[0050] In some embodiments of the present invention described above, the positioning component 310 includes a lateral limiting structure 311, which is used to position the positioning rod 222 on the movable track 220 laterally, thereby ensuring that the positioning rod 222 is accurately positioned in the lateral direction, and thus ensuring that the movable track 220 is accurately positioned in the lateral direction.

[0051] Specifically, the lateral limiting structure 311 includes two lateral limiting plates 3111 arranged opposite to each other. Each lateral limiting plate 3111 is provided with an elastic abutment section 3112 facing the other lateral limiting plate 3111. The two elastic abutment sections 3112 can elastically clamp the positioning rod 222 to ensure that the positioning rod 222 can be in a specified position in the lateral direction.

[0052] More specifically, the openings of the two elastic abutment sections 3112 facing the movable track 220 gradually decrease as the positioning rod 222 rises, to ensure that the positioning rod 222 can smoothly enter between the two elastic abutment sections 3112, thereby ensuring that the positioning rod 222 can be accurately positioned.

[0053] In some embodiments of this utility model, the positioning component 310 further includes a longitudinal limiting structure 312, which includes two longitudinal limiting plates 3121 arranged opposite to each other. An electromagnetic lock 3122 is also provided between the longitudinal limiting plate 3121 and the positioning rod 222, and the electromagnetic lock 3122 is used to lock the longitudinal limiting plate 3121 and the positioning rod 222.

[0054] In some embodiments of the present invention described above, the positioning component 310 further includes a longitudinal limiting structure 312, which includes two longitudinal limiting plates 3121. The two longitudinal limiting plates 3121 are arranged opposite to each other and can limit the longitudinal direction of the positioning rod 222, thereby ensuring that the positioning rod 222 can be accurately positioned in both the lateral and longitudinal directions, and ensuring that the movable track 220 and the fixed track 210 can be accurately connected.

[0055] Furthermore, an electromagnetic lock 3122 is provided between the longitudinal limiting plate 3121 and the positioning rod 222. The electromagnetic lock 3122 can lock the positions of the longitudinal limiting plate 3121 and the positioning rod 222, ensuring that when the positioning rod 222 reaches the designated position, that is, when the movable track 220 is precisely aligned with the fixed track 210, the position of the positioning rod 222 can be locked, ensuring the stability and safety of the movable track 220.

[0056] Optionally, the locking block of the electromagnetic lock 3122 is adapted to the positioning rod 222, thereby ensuring that the positioning rod 222 is accurately positioned.

[0057] Preferably, the locking block has a wedge-shaped structure.

[0059] In some embodiments of the present invention described above, a mating part 221 is provided on the movable track 220, and a connecting part 211 is provided on the fixed track 210. The connecting part 211 and the mating part 221 cooperate. When the positioning rod 222 is precisely positioned, the mating part 221 on the movable track 220 and the connecting part 211 on the fixed track 210 also cooperate with each other, thereby forming an integral conveying track 200.

[0060] In some embodiments of this utility model, the lifting assembly is a wire rope lift. The wire rope of the wire rope lift is connected to the positioning rod 222.

[0061] Specifically, a pull ring is provided on the positioning rod 222, and the wire rope is connected to the pull ring.

The moving assembly 120 includes a left moving wheel 121, a right moving wheel 122 and a quick-change mechanism 123. The track drive assembly 110 is connected to either of the left moving wheels 121.

The quick-change mechanism 123 is connected to the right moving wheel 122 and is used to drive the left moving wheel 121 and the right moving wheel 122 to move closer to each other to clamp the movable track 220, or to drive the left moving wheel 121 and the right moving wheel 122 to move away from each other to release the movable track 220.

[0068] In some of the embodiments of the present invention described above, the device body 100 is provided with a track drive assembly 110 and two sets of moving assemblies 120. The track drive assembly 110 and the two sets of moving assemblies 120 can drive the device body 100 to be transported along the conveying track 200 to complete the liquid spraying.

[0069] Specifically, the moving component 120 includes a left moving wheel 121, a right moving wheel 122, and a quick-change mechanism 123. The left moving wheel 121 and the right moving wheel 122 are respectively disposed on both sides of the movable track 220. The quick-change mechanism 123 is connected to the right moving wheel 122 and is used to drive the left moving wheel 121 and the right moving wheel 122 to move closer to each other to clamp the movable track 220, or to drive the left moving wheel 121 and the right moving wheel 122 to move away from each other to release the movable track 220. The quick-change mechanism 123 is connected to the right moving wheel 122 and is used to drive the left moving wheel 121 and the right moving wheel 122 to move closer to each other or move away from each other. By clamping the movable track 220 with the left moving wheel 121 and the right moving wheel 122, the track driving component 110 is connected to either of the left moving wheels 121, thereby driving the device body 100 to be conveyed along the conveying track 200 and completing the liquid spraying.

[0070] Specifically, the quick-change mechanism 123 includes a handle 1231, a support 1232, and a telescopic rod 1233. The telescopic rod 1233 passes through the support 1232 and can reciprocate along a first direction. The right moving wheel 122 is connected to the first end of the telescopic rod 1233, and the second end of the telescopic rod 1233 is rotatably connected to the handle 1231. A connecting rod 1234 is provided between the handle 1231 and the support 1232.

[0071] By driving the handle 1231 to rotate, the telescopic rod 1233 is driven to reciprocate along the first direction, thereby driving the left moving wheel 121 and the right moving wheel 122 to move closer to or further away from each other.

[0072] In some embodiments of this utility model, the device body 100 includes a liquid storage tank 130 and a centrifugal nozzle 140.

[0073] In some embodiments of the present invention described above, the device body 100 includes a liquid storage tank 130 and a centrifugal nozzle 140. The centrifugal nozzle 140 is disposed on the liquid storage tank 130. The centrifugal nozzle 140 and the liquid storage tank 130 are connected by a pipeline. The liquid in the liquid storage tank 130 can be sprayed out through the centrifugal nozzle 140 to complete the liquid spraying.

[0074] Specifically, a swing mechanism 150 is provided between the centrifugal nozzle 140 and the liquid storage tank 130. The swing mechanism 150 is used to drive the centrifugal nozzle 140 to swing left and right, thereby realizing large-scale spraying of crops in the greenhouse and ensuring uniform liquid spraying of crops in the greenhouse.

[0075] Optionally, the swing mechanism 150 is driven by a swing head motor.

[0076] In some embodiments of this utility model, a front-to-back adjustment mechanism 160 is also included. The front-to-back adjustment mechanism is disposed between the swing mechanism 150 and the centrifugal nozzle 140. The front-to-back adjustment mechanism 160 includes a first U-shaped plate 161, a second U-shaped plate 162 and a locking bolt.

The threaded hole cooperates with the locking bolt, and the locking bolt passes through the arc-shaped groove 163 and connects with the threaded hole.

[0077] In some embodiments of the present invention described above, by providing a front-to-back adjustment mechanism 160, which is located between the swing mechanism 150 and the centrifugal nozzle 140, the front-to-back position of the centrifugal nozzle 140 can be adjusted, thereby allowing the position of the centrifugal nozzle 140 to be changed according to actual needs, achieving a more suitable angle adjustment.

[0079] In some specific implementations, electric adjustment can also be used.

[0080] In some embodiments of the present invention, the centrifugal nozzle 140 includes a nozzle body 141 and a nozzle drive assembly 145. A centrifugal disk 143 is provided at the first end of the nozzle body 141, and a passive fan blade 142 is provided on the centrifugal disk 143.

[0081] A turbine blade 144 is provided at the second end of the nozzle body 141 away from the centrifugal disk 143. A flow guide channel is provided between the first end and the second end of the nozzle body 141. The nozzle drive assembly 145 is connected to the turbine blade 144 for driving the turbine blade 144 to rotate.

[0082] In some embodiments of the present invention described above, a centrifugal disc 143 is provided at the first end of the nozzle body 141. The centrifugal disc 143 is disposed at the liquid outlet of the nozzle body 141. By using the nozzle drive assembly 145 to drive the turbine fan blade 144, the turbine fan blade 144 can achieve long-distance liquid spraying. The wind force of the turbine fan blade 144 can directly drive the passive fan blade 142 of the centrifugal disc 143. The passive fan blade 142 drives the centrifugal disc 143 to throw out liquid, thereby achieving an atomization effect.

[0083] Furthermore, the size of the turbine blade 144 is larger than the size of the passive blade 142. Preferably, the size of the turbine blade 144 is at least twice the size of the passive blade 142.

[0084] It should be noted that in the existing technology, the nozzle uses a motor to directly drive the centrifugal disc 143 to rotate in order to achieve the atomization effect. In actual use, the atomization effect requires a very high motor speed, generally around 10,000 rpm. Furthermore, the current required for the motor to drive the centrifugal nozzle 140 is very large, resulting in very high efficiency. Moreover, using a motor to directly drive the centrifugal disc 143 presents a waterproofing issue. If liquid enters the motor, it will be damaged. Therefore, the structure of the motor-driven centrifugal nozzle 140 needs to be designed to be very complex, and the manufacturing process is very difficult.

[0085] The centrifugal nozzle 140 of this invention connects the nozzle drive assembly 145 to the turbine fan blade 144. The nozzle drive assembly 145 is not directly connected to the centrifugal disc 143, thus avoiding direct contact between the liquid in the centrifugal disc 143 and the nozzle drive assembly 145. This effectively prevents water from entering the nozzle drive assembly 145 and solves the problem of water damage.

[0086] Secondly, because the turbine blade 144 has a high wind pressure and its diameter is larger than that of the passive blade 142 on the centrifugal disk 143, it can drive the passive blade 142 to a very high speed to achieve atomization.

[0087] According to actual measurements, when the turbofan speed reaches 10,000 rpm, the speed of the centrifugal disk 143 blades reaches approximately 15,000 rpm. This results in smaller and more uniform water droplets exiting the centrifugal disk 143.

[0088] In some embodiments of this utility model, the fixed track 210 is an S-shaped track. An S-shaped track enables a single spraying device to spray the entire area within a single greenhouse; alternatively, by setting up an S-shaped track between multiple greenhouses, a single spraying device can complete spraying of the entire area within multiple greenhouses, thereby improving production efficiency and reducing enterprise costs.

[0089] During actual spraying, the centrifugal nozzle 140 has the lowest water output when spraying vertically downwards (we'll call this position 0°), as it's closest to the crop. Conversely, the flow rate is highest when the oscillating nozzle is at 90°. (Experimental results show that the nominal flow rate is highest at 45°). The nozzle drive assembly 145 and the oscillating motor are synchronized. The wind force is also lowest at 0° (closest to the crop) and highest at 90°. The oscillating motor completes one cycle every 4 meters of travel by the track drive assembly 110 (the nozzle's mist area is 4 square meters, covering every 2 meters). It pauses for 3 seconds at 90° (experimental results show this pause provides the most even spraying). The oscillation frequency of the oscillating motor and nozzle drive assembly 145 is PID-shaped based on the speed of the track drive assembly 110.

[0090] It should be noted that, since this utility model adopts an S-shaped track, the spraying device can turn automatically. Therefore, it is preferable to temporarily stop spraying when turning, and continue spraying after the turn is completed, so as to ensure uniform spraying and avoid problems such as pesticide damage and inadequate control caused by excessively high concentration in local areas during the spraying process.
