Referring to fig. 1 to 3, the bio dispenser of the present invention includes a bio container storage chamber 100, a dispensing chamber 200, a dispensing part 300, a transfer means 400, and a barrier guide 500. The bio-container storage chamber 100 is located at an upper portion of the bio-dispenser to hold a bio-container for containing organisms capable of preventing insect damage. The administration chamber 200 is positioned below the bio-container storage chamber 100 and communicates with the bio-container storage chamber 100. The dispensing cavity 200 is cylindrical, and a plurality of dispensing parts 300 are provided on the sidewall of the dispensing cavity 200. Launch portion 300 is a cylindrical structure extending radially outward from the side wall of launch chamber 200 to the outside of launch chamber 200. The transfer device 400 is disposed in the loading chamber 200, and the transfer device 400 can receive and transfer the biocontainers from the biocontainer storage chamber 100. The blocking and guiding device 500 is provided on the inner wall of the administration chamber 200, and blocks and guides the biocontainer so that the biocontainer can smoothly enter the administration part 300 to be administered while the biocontainer is being conveyed by the conveyor 400.

Since the bio dispenser of the present invention is provided with the plurality of dispenser parts 300 and the blocking guide 500 is provided on the downstream side of the rotation direction of the transfer part 420 of each dispenser part 300, it is possible to dispense bio-containers in multiple directions in one operation process, and the dispensing is reliable and efficient. Meanwhile, the biological dispenser has the advantages of simple overall structure, easy operation, convenient maintenance and replacement, small volume and light weight, and is suitable for being carried and matched with an unmanned aerial vehicle.
In one embodiment of the present invention, the biological container storage chamber 100 is configured as an inverted truncated cone-shaped hollow container with a smooth inner wall, and the inverted truncated cone-shaped hollow container can conveniently collect the biological containers into the throwing cavity 200. The bottom of the dosing chamber 200 is closed and the transfer device 400 is mounted to the bottom plate 210 of the dosing chamber 200.
Referring to fig. 2, the transfer device 400 includes a stepping motor 410 and a transfer part 420. The stepping motor 410 is preferably provided as a stepping motor of a straight cylinder type. The stepping motor 410 is vertically installed at the base plate 210, and an output end of the stepping motor 410 is detachably connected to the transferring part 420. The transferring part 420 includes a transferring shaft 421, a fan-shaped driving part 422, and a star-shaped blocking part 423, and a lower end of the transferring shaft 421 passes through a central mounting hole of the fan-shaped driving part 422 and is detachably connected to an output end of the stepping motor 410. The fan-shaped driving portion 422 is mounted on the transmission shaft 421 and can rotate synchronously with the transmission shaft 421. The star blocking portion 423 is installed at the upper end of the transferring shaft 421, and the star blocking portion 423 can also be rotated in synchronization with the transferring shaft 421.
The star block portion 423 includes a plurality of star corners, and a gap between the star corners allows the bio-container to smoothly enter the throwing chamber 200 from the bio-container storage chamber 100 and reach between the fan blade shaped driver 422 and the star block portion 423. The biocontainer of the present invention is preferably spherical. The shape of the fan-shaped driving portion 422 is similar to that of a fan blade, and each blade of the fan blade is bent in the same direction, and the gap between adjacent blades is larger than the diameter of the biological container. The fan-shaped driving portion 422 can drive the biological container entering the releasing cavity 200 to move, when the biological container moves to the inlet of the releasing portion 300, the biological container is blocked by the blocking guiding device 500, part of the biological container enters the inlet of the releasing portion 300, part of the biological container can move upwards, the star angle of the star-shaped blocking portion 423 can block the biological container from moving upwards, and therefore the biological container is enabled to smoothly enter the inlet of the releasing portion 300 under the driving of the fan-shaped driving portion 422 and the matching of the blocking guiding device 500 and the star-shaped blocking portion 423 so as to achieve releasing. Preferably, the number of star points of the star blocking portion 423 is equal to the number of blades of the fan-blade shaped carrying portion 422, and each star point and each blade are arranged in vertical alignment with each other, so that the biocontainer can be more reliably transferred to the launching portion 300.
The thickness of the above-mentioned vane shape leading portion 422 is preferably set to 2-3mm, and the thickness of the star blocking portion 423 is preferably set to 3mm. The diameter of the biocontainer is preferably set to 38-42mm, more preferably to 40mm.
In this embodiment, the blocking guide 500 is preferably provided as an arc-shaped plate fixed to the inner wall of the launching chamber 200. The arc-shaped baffle is located between the star-shaped blocking portion 423 and the fan-shaped driving portion 422 in the vertical direction, and the bending direction of the arc-shaped baffle may be substantially the same as the bending direction of the blades of the fan-shaped driving portion 422. Preferably, the lower portion of the arc-shaped barrier is located at a downstream side in the rotation direction of the upper transfer part 420 so as to block the upward play of the biocontainer. The arc plate is disposed on the downstream side of the rotation direction of the transfer part 420 of the launch part 300. When the biological container is driven by the fan blade-shaped driving portion 422 to move, the biological container is blocked and guided by the arc-shaped plate, and is blocked by the star angle of the upper star-shaped blocking portion 423, so that the biological container can smoothly enter the inlet of the releasing portion 300 to realize releasing. Note that the rotation direction of the conveyor 400 is from the side of the throwing portion 300 where no arc is provided to the side where the arc is provided, and the biocontainer can smoothly enter the throwing portion 300 under the baffling and guiding of the arc. That is, in the configuration shown in fig. 1, the delivery device 400 moves the biocontainer in a counterclockwise direction to effect dispensing. In addition, since the arc-shaped plate serves to convey and guide the biocontainer, it is preferable that the arc-shaped plate is bent with a radius larger than that of the spherical biocontainer.
In this embodiment, the bio dispenser of the present invention further comprises an accelerator 600. The acceleration device 600 is provided at the outlet of the dispenser 300, and can accelerate the biocontainer being transferred from the dispenser 300.
Specifically, the acceleration device 600 includes two rotation devices which can rotate reversely with respect to each other at the same rotation speed, and between which there is a transfer gap, and the bio-containers transferred from the transfer device 400 enter the transfer gap of the acceleration device 600 near the outlet of the launch portion 300 and are accelerated out of the transfer gap by being driven by the two rotation devices. Among them, the two rotation means are preferably two outer rotor driving motors 610a and 610b. The two outer rotor driving motors 610a and 610b are installed at the same level and located at both sides of the input part 300, respectively. The installation gap of the two outer rotor driving motors 610a and 610b is set to be smaller than the diameter of the biocontainer so as to press the biocontainer passing through the installation gap, increasing the frictional force between the biocontainer and the acceleration device 600, thereby accelerating the biocontainer. Preferably, the installation gap of the two outer rotor driving motors 610a and 610b is smaller than the diameter of the bio-container by 1-2mm.
The acceleration device 600 further comprises a plurality of friction resistance rings 611, at least one of said friction resistance rings 611 being mounted on the outer circumference of each rotation means. In the present embodiment, a resistance friction ring 611 is mounted around the outer circumference of each of the outer rotor drive motors 610a and 610b, and the resistance friction rings 611 of the outer circumferences of the two outer rotor drive motors 610a and 610b are at the same level. Preferably, the friction resistance ring 611 is a rubber ring. The rotation directions of the two outer rotor drive motors 610a and 610b are set as follows: as shown in fig. 1, when the outer rotor driving motor 610a is rotated in a clockwise direction and the outer rotor driving motor 610b is rotated in a counterclockwise direction as viewed from above the biocontainer storage chamber 100 downward, the biocontainer moves forward at a faster speed after passing through the mounting gap due to the action of the resistive friction ring 611.
An acceleration device 600 may be provided at an outlet of each of the dispensers 300 to accelerate the bio-containers at the outlet of each of the dispensers 300. Preferably, as shown in fig. 1, the dispenser 300 and the accelerator 600 are provided right in front of, right to the left of and right of the bio dispenser, respectively, so that the three dispensers 300 of the bio container can be dispensed at the same time by one operation. When the unmanned aerial vehicle flies in a straight line for operation, the tracks of the biological containers thrown by the biological thrower are 3 rows of throwing tracks which are parallel to each other. Of course, the acceleration device may not be provided in the directly front launching unit 300, and the biological container in the launching unit 300 may be freely dropped from the launching unit 300. The rotation speed of the accelerator 600 can be adjusted, and different rotation speeds of the accelerator 600 can provide different initial speeds in the horizontal direction to the thrown bio-container, so that the distance of the throw-in distance of the bio-container can be controlled by setting the rotation speeds of the two outer rotor driving motors 610a and 610b, that is, the row spacing of the throw-in trajectory of the formed bio-container can be controlled.
When the dispenser of the present invention is applied to paddy field throwing, the biocontainer may be configured to be suitable for paddy field throwing, i.e., the biocontainer does not need to be opened when being thrown, and the accelerating device 600 only accelerates the biocontainer.
When the dispenser of the present invention is used for land dispensing, a separating impact plate may be disposed at the dispensing end of each acceleration device 600, and the biological containers after acceleration may be decomposed and dispensed after impacting the separating impact plate, thereby achieving the suspension of the biological containers. However, in land operation, the throwing distance of the two sides of the biological dispenser is limited by the position of the separating impact plate, namely, the separating impact plate determines the throwing distance. Thus, the distances of the dropping parts 300 at both sides of the bio dispenser can be controlled only by adjusting the position of the separation impact plate, and thus the dropping distance can be adjusted only within a limited range. It is of course also possible to decompose the bio-container by pressing by making the installation gap of the two outer rotor driving motors 610a and 610b small.
Preferably, a bio-container loading passage may be provided at an upper end of the bio-container storage chamber 100 to facilitate the addition of the bio-container into the bio-container storage chamber 100.
Preferably, the bio-dispenser according to the present invention may further comprise a control means for speed and on-off control of the transfer means 400 and the acceleration means 600. The control means comprises an electronic governor (not shown) which controls the speed of rotation of the stepper motor 410 and hence the speed at which the biocontainers are conveyed by the conveyor 400; the electronic governor can control the rotation speed of the two outer rotor driving motors 610a and 610b, thereby controlling the distance of the bio-container throwing.
In addition, the biological dispenser can be provided with an independent power supply and control system, and can also be directly connected into the power supply and control system of the unmanned aerial vehicle.
In this embodiment, referring to fig. 4, the bio-dispenser is directly connected to the power supply and the control system of the unmanned aerial vehicle, the power supply of the unmanned aerial vehicle supplies power to the bio-dispenser, and the control signal of the unmanned aerial vehicle controls the action of the bio-dispenser. Specifically, unmanned aerial vehicle's control system is to step motor 410 output control signal, and control step motor 410 rotates, and step motor 410 drives conveying shaft 421 and rotates, and then drives biological container and remove and get into input portion 300. The control system of the unmanned aerial vehicle outputs control models to the outer rotor driving motor 610a and the outer rotor driving motor 610b, the outer rotor driving motor 610a and the outer rotor driving motor 610b are controlled to rotate, and the biological container is accelerated and thrown by the outer rotor driving motor 610a and the outer rotor driving motor 610b at the outlet of the throwing portion 300, so that the plant protection operation is realized by using the biological throwing device.
Referring to fig. 1 and 4, the specific process of the bio-dispenser of the present invention for dispensing a bio-material is as follows: a bio-container containing a living being is loaded into the bio-container storage chamber 100, and the bio-container enters the launch chamber 200 from the bio-container storage chamber 100. The accelerating device 600 and the conveying device 400 are started, and the fan-shaped driving portion 422 of the conveying device 400 drives the biological containers to move in the throwing cavity 200. When the biological container moves to the blocking and guiding device 500, part of the biological container enters the inlet of the throwing portion 300, and the part of the biological container moves upwards due to the blocking of the blocking and guiding device 500, and the star-shaped blocking portion 423 can block the biological container from moving upwards, so that the biological container can be ensured to smoothly enter the inlet of the throwing portion 300 under the blocking and guiding of the blocking and guiding device 500. The bio-container enters the conveying gap of the acceleration device 600 at the outlet of the throwing portion 300 and is driven by the acceleration device 600 to accelerate, and the accelerated bio-container flies out in the horizontal direction to realize the throwing. Since the feeding portions 300 are provided right in front, right left, and right of the side wall of the feeding chamber 200, the bio-containers can be simultaneously fed in three directions in one operation. Preferably, the biological container may be an artificial bee nest, more preferably, the artificial bee nest is a trichogramma bee nest.
In the above working process, the speed of the conveyer 400 and the accelerator 600 is controlled by an electronic governor to meet the actual working requirements.
Referring to fig. 5, it can be seen from the structure and practical operation effect of the bio-dispenser of the present invention that the bio-dispenser of the present invention can achieve multi-directional dispensing of a bio-container, and the dispensing is uniform and reliable.
Although the bio-dispenser according to the present invention is constructed such that the frictional resistance rings surrounding the outer rotor driving motors 610a and 610b are made of rubber in the above exemplary embodiment, the frictional resistance rings of the present invention may be made of other materials having a large friction coefficient, such as plastic.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
