TECHNICAL FIELD

[0002] The importance of crop pollination to agricultural production is self-evident. In traditional agricultural production, crops mainly rely on natural pollination, which depends on external environment and biological media such as wind and insects. Under the condition of natural pollination, environmental factors have a great influence, such as climate change, environmental pollution or reduction of biological diversity, which may lead to uneven pollination and reduced pollination efficiency. If crops cannot be successfully pollinated, it will affect the growth and development of crops, cause the size and maturity of fruits to be inconsistent, and result in reduced yield.

[0003] In the process of long-term co-evolution with plants, the activity habits of bees and the morphological structure, physiological and biochemical characteristics of plants, and the best time for pollination have formed a mutually dependent relationship, making bees the most ideal pollinating insects. In order to improve the pollination rate of crops, existing technologies have used bees for assisted pollination. For example, a beehive for small-area crop bee pollination disclosed in the authorized publication No. CN204762810U can feed bees with sugar water and pollen at the same time by setting a feeding device containing a pollen box and a sugar water box above the box, feed the bees with pollen, and make the bee colony complete the pollination task of small-area crops with long flowering period and less pollen source, thus meeting the needs of crop pollination with long flowering period. However, this kind of pollination beehive has the problem that, during use, the pollen box is far away from the nest door, only a part of bees can be fed, and most of the bees do not pass through the pollen box before leaving the beehive, which results in a part of bees not having pollen or having limited amount of pollen on their bodies before leaving the beehive, thus leading to low pollination rate.

[0025] Please refer to Figure 3 and Figure 5 In particular, the pollen delivery device 23 comprises a main conveyor belt 231, two main drive shafts 232 and a main drive motor 233. The two main drive shafts 232 are respectively arranged at both ends of the pollen discharge channel 211 and are close to the top of the pollen discharge channel 211. The two main drive shafts 232 are parallel to each other and can rotate freely. The main conveyor belt 231 is annularly sleeved on the two main drive shafts 232. The upward conveying surface of the main conveyor belt 231 is opposite to the first pollen discharge hole 212 and is in contact with the pollen discharge port 222 of the pollen storage bin 22. The main drive motor 233 is installed on the outer side wall of the pollen discharge box 21. The shaft end of the main drive motor 233 penetrates into the pollen discharge channel 211 and is connected with one of the main drive shafts 232. The main drive motor 233 drives the main conveyor belt 231 to rotate in the pollen discharge channel 211. During the rotation of the main conveyor belt 231, the pollen discharged from the pollen discharge port 222 of the pollen storage bin 22 is smeared and adhered to the conveying surface of the main conveyor belt 231. The rotation of the main conveyor belt 231 can bring the pollen into the pollen discharge channel 211. During the rotation, a part of the pollen will fall to the bottom of the pollen discharge channel 211. When the bees climb into or out of the beehive body 10 from the open end of the pollen discharge channel 211, the bees will crawl along the conveying surface of the main conveyor belt 231 or the bottom of the pollen discharge channel 211.

[0026] Please continue to refer to Figure 5 Further, in order to make the pollen in the pollen storage bin 22 discharge smoothly, a first auxiliary pollen discharge roller 223 that can rotate freely is arranged in the pollen discharge port 222 of the pollen storage bin 22. The first auxiliary pollen discharge roller 223 is parallel to the main drive shaft 232 of the pollen delivery device 23 and is in frictional contact with the conveying surface of the main conveyor belt 231. When the main conveyor belt 231 rotates, the first auxiliary pollen discharge roller 223 can be driven to rotate by friction. During the rotation of the first auxiliary pollen discharge roller 223, the roller surface of the first auxiliary pollen discharge roller 223 will adhere to the pollen in the pollen storage bin 22, and when the roller surface is in frictional contact with the conveying surface of the main conveyor belt 231, the adhered pollen will be transferred to the conveying surface of the main conveyor belt 231.

[0027] In the above embodiment, the conveying surface of the main conveying belt 231 is provided with a layer of fur or fiber material that can adhere to the pollen, and the surface of the first auxiliary pollen discharge roller 223 is also circumferentially provided with a layer of fur or fiber material that can adhere to the pollen. The fur or fiber layer can improve the adhesion of the pollen and increase the amount of pollen adhered, which is conducive to increasing the amount of pollen carried by the bees during the process of crawling on the conveying surface of the main conveying belt 231.

[0028] Please continue to see Figure 3 、 Figure 5 and Figure 7 Furthermore, in order to improve the pollen carrying rate of bees when they go out to collect honey, the pollen conveying device 23 further comprises a secondary conveying belt 234, two secondary transmission shafts 235, and a secondary drive motor 236. The two secondary transmission shafts 235 are respectively transversely arranged at both ends of the pollen discharge channel 211 and are close to the bottom of the pollen discharge channel 211. The two secondary transmission shafts 235 are parallel to each other and can freely rotate. The secondary conveying belt 234 is annularly sleeved on the two secondary transmission shafts 235. The secondary conveying belt 234 is arranged opposite to the main conveying belt 231, and the secondary conveying belt 234 and the main conveying belt 231 provide a crawling path for the bees to enter and exit the beehive body 10. The secondary drive motor 236 is installed on the outer wall of the pollen discharge box 21. The shaft end of the secondary drive motor 236 is axially connected with one of the secondary transmission shafts 235. A second pollen discharge through hole 213 is formed in the lower end of the outer wall of the pollen discharge box 21 and is in communication with the pollen discharge channel 211. The second pollen discharge through hole 213 is opposite to the conveying surface of the secondary conveying belt 234. A secondary storage bin 24 with an open upper end for filling pollen is installed on the lower end of the outer wall of the pollen discharge box 21. The open end of the secondary storage bin 24 is opposite to the second pollen discharge through hole 213. A second auxiliary pollen discharge roller 241 that can freely rotate is arranged in the secondary storage bin 24. The second auxiliary pollen discharge roller 241 is parallel to the secondary transmission shaft 235. The roller surface of the second auxiliary pollen discharge roller 241 protrudes from the open end of the secondary storage bin 24 and is in frictional contact with the conveying surface of the secondary conveying belt 234. The secondary drive motor 236 drives the secondary conveying belt 234 to rotate in the pollen discharge channel 211. When the secondary conveying belt 234 rotates, the second auxiliary pollen discharge roller 241 is driven to rotate by friction. During the rotation of the second auxiliary pollen discharge roller 241, the roller surface of the second auxiliary pollen discharge roller 241 adheres to the pollen in the secondary storage bin 24 and transfers the adhered pollen to the conveying surface of the secondary conveying belt 234 when in frictional contact with the conveying surface of the secondary conveying belt 234.

[0029] In order to facilitate the pollen in the bottom of the auxiliary storage 24 to be discharged smoothly, a third auxiliary discharge roller 242 freely rotatable is arranged at the lower end of the second auxiliary discharge roller 241, the third auxiliary discharge roller 242 is parallel and aligned with the second auxiliary discharge roller 241, the third auxiliary discharge roller 242 is arranged close to the bottom of the auxiliary storage 24, and the third auxiliary discharge roller 242 is in frictional contact with the roller surface of the second auxiliary discharge roller 241. When the second auxiliary discharge roller 241 rotates under the frictional force of the auxiliary conveying belt 234, the third auxiliary discharge roller 242 is driven to rotate by the frictional force, and the third auxiliary discharge roller 242 rotates to adhere to the pollen in the auxiliary storage 24 and transfer the adhered pollen to the second auxiliary discharge roller 241.

[0030] In this embodiment, the conveying surface of the auxiliary conveying belt 234 is also provided with a layer of pollen-adhesive material such as fur or fiber, and the roller surfaces of the second auxiliary discharge roller 241 and the third auxiliary discharge roller 242 are also circumferentially provided with a layer of pollen-adhesive material such as fur or fiber. The fur or fiber layer can improve the adhesion of pollen and increase the amount of pollen adhered, which is beneficial for the bees to increase the amount of pollen carried during crawling on the conveying surface of the auxiliary conveying belt 234.

[0031] In the stage of pollinating crops, the main drive motor 233 and the auxiliary drive motor 236 drive the main conveying belt 231 and the auxiliary conveying belt 234 to run slowly, conveying the pollen in the pollen storage 22 and the auxiliary storage 24 into the discharge channel 211. During the conveying process, the conveying surfaces of the main conveying belt 231 and the auxiliary conveying belt 234 will adhere to pollen. When the bees crawl into or out of the beehive body 10 from the open end of the discharge channel 211, the bees will crawl along the conveying surface of the main conveying belt 231 or the conveying surface of the auxiliary conveying belt 234 in the discharge channel 211. During the crawling process, the bees' bodies and claws will adhere to pollen. When the bees go out to collect nectar, the pollen carried by the bees will pollinate crops, thereby increasing the pollination probability of crops.

[0032] Please refer to Figure 8In a preferred embodiment, the main conveyor belt 231 and the auxiliary conveyor belt 234 can be synchronously driven by a main driving motor 233, specifically, a pair of auxiliary gears 237 are arranged at the shaft ends of the adjacent main transmission shaft 232 and auxiliary transmission shaft 235 at the same side, the two auxiliary gears 237 are meshed with each other, the main driving motor 233 is installed on the outer side wall of the powder discharging box 21, and a main gear 238 is installed at the shaft end of the main driving motor 233 and is meshed with one of the auxiliary gears 237, when the main driving motor 233 drives one of the auxiliary gears 237 to rotate, the other auxiliary gear 237 can be linked to rotate, so that the main conveyor belt 231 and the auxiliary conveyor belt 234 are synchronously driven. The main driving motor 233 can also be installed between the two auxiliary gears 237, the two auxiliary gears 237 are not in contact with each other, the main gear 238 installed at the shaft end of the main driving motor 233 is meshed with the two auxiliary gears 237 at the same time, and the main driving motor 233 drives the main conveyor belt 231 and the auxiliary conveyor belt 234 to rotate at the same time.

[0033] In the above embodiment, the pollen storage bin 22 and the auxiliary storage bin 24 are detachably installed at the upper end and the lower end of the powder discharging box 21 by plug-in or screw fixation, so as to facilitate replacement or manual addition of pollen.

[0034] The beehive facilitating pollination of crops can be used for directional pollination of different crops, for example, when the beehive is used for directional pollination of fruit corn, after the fruit corn enters the pollination stage, the beehive is moved to the planting area of the fruit corn, the pollen storage bin 22 and the auxiliary storage bin 24 of the pollen supply device 20 are filled with pollen for pollination of the fruit corn, the main driving motor 233 and the auxiliary driving motor 236 are powered by an external power supply or a storage battery, the main driving motor 233 and the auxiliary driving motor 236 are turned on to drive the main conveyor belt 231 and the auxiliary conveyor belt 234 to convey the pollen in the powder discharging channel 211, so that the bees carry the pollen to assist the pollination of the fruit corn during the process of going out to collect nectar.
