Technical Field

[0001] The invention relates to the technical field of weed seed sorting and processing, in particular to a falling type weed seed automatic sorting device. Background Art

[0002] In the prior art, whether it is the inspection of grain seeds in customs or the screening of grain seeds in agricultural technology, it is necessary to sort out the weed seeds mixed inside, otherwise it will seriously affect the quality of grain seeds.

[0003] The weed seed sorting equipment in the prior art, for example: the technical scheme of the authorization announcement number: CN114310955B discloses "a weed seed sampling robot for grains"; the technical scheme includes a robot shell, the lower end of which is equipped with a crawler walking mechanism, the upper end of which is equipped with a multi-dimensional swinging mechanical arm, and the interior of the robot shell is also equipped with a vertical partition, which divides the internal space of the robot shell into a control room on the left and a sampling room on the right, and a sampling plate is also arranged on the upper side of the sampling room on the right. The controller of the present invention controls the mechanical arm to cooperate with the suction pipe and the negative pressure fan to suck the grains into the upper part of the sampling plate, and after taking pictures, it is judged whether there are other colored substances in the grains through image recognition. According to the recognition result, it can be selected to be put back into the barn or placed in the sampling room, so that the weed seeds mixed in the grains can be sampled out more conveniently, and the whole process is automated, saving a lot of time and manpower and material resources.

[0004] In the above technical solution, weed seeds in grains are sorted by setting up a sampling robot. Specifically, sampling and sorting need to be carried out in the grain bin. If weed seeds exist in the sampled grains, the grains are stored and then sorted.

[0005] The above-mentioned technical solution obviously requires a long sorting time, and the sorting work needs to be carried out in a large granary. The overall structural setting relies on robots for sorting, and the structural design is relatively complex. The specific sorting efficiency needs to be improved.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a falling-type weed seed automatic sorting device with a reasonable structure that effectively improves the sorting efficiency and quality. Summary of the invention

[0007] The purpose of the present invention is to provide a falling type weed seed automatic sorting device in view of the shortcomings of the prior art; the technical scheme is as follows: A drop-type weed seed automatic sorting device comprises a storage bin at the top layer, a drop-type barrel extending vertically downward is arranged at the bottom of the storage bin, the drop-type barrel is a rectangular barrel structure, a feed inlet is arranged at the upper end of the drop-type barrel, a discharge outlet is arranged at the lower end, and a receiving frame is arranged below the discharge outlet; The middle part of the blanking barrel is provided with an outwardly extending part, and the side wall of the outwardly extending part is correspondingly installed with an illumination device and a camera recognition device for identifying weed seeds; when the material enters the blanking barrel from the feeding port and falls into the blanking barrel, the camera recognition device takes a picture of the material and correspondingly identifies the weed seeds under the illumination of the illumination device when the material passes through the outwardly extending part; The lower end of the blanking barrel is also provided with two separation barrel plates, which are hingedly installed through hinges, and a push mechanism is installed on the left and right sides of the two separation barrel plates respectively. The main shafts of the push mechanisms on both sides are respectively installed on the separation barrel plates through hinges. Under the action of the push mechanisms on both sides, the two separation barrel plates are tilted to the left at the same time, and a sorting frame is correspondingly provided below the two separation barrel plates; When the camera recognition device recognizes that weed seeds are mixed in the falling material, the pushing mechanisms on both sides are opened accordingly, and the two separation cylinder plates are tilted to the left, so that the falling direction of the material in the drop barrel changes, and the material falls to the left into the sorting frame. This part of the material is mixed with weed seeds. After that, the two separation cylinder plates are reset by the pushing mechanism, and the material falls normally into the receiving frame.

[0008] Furthermore, the bottom of the storage bin is configured as a funnel-shaped structure, and the blanking barrel is configured at the bottom of the storage bin; a vibration motor is also installed on the storage bin, and the material in the blanking barrel is vibrated by the vibration motor.

[0009] Furthermore, the internal dimensions of the blanking barrel are set accordingly so that only one layer of material enters the blanking barrel each time, and the material does not pile up in the blanking barrel.

[0010] Furthermore, the outer expansion part is a trapezoidal structure as a whole, and the material will fall down accordingly after falling into the outer expansion part.

[0011] Furthermore, the blanking barrel is provided with fixed plates on both sides and separation barrel plates on both sides, the separation barrel plates are correspondingly hingedly installed through hinges, and the two separation barrel plates are correspondingly tilted between the fixed plates on both sides.

[0012] Furthermore, the two push mechanisms connected to the two separation cylinder plates are in a synchronous drive form, the push mechanism on the left is set in a retracting form, and the push mechanism on the right is set in a propulsion form.

[0013] Furthermore, the receiving frame and the sorting frame are of the same size.

[0014] Beneficial effects: The present invention has the following beneficial effects: 1) This device is set as a drop-type sorting device. The material is dropped in a single layer in the drop barrel. The lighting device is used to illuminate and the camera recognition device is used to identify the seeds. Then, the push mechanism drives the separation barrel plate to change the drop direction, so that the material mixed with weed seeds falls into the sorting frame, thereby realizing the sorting of weed seeds. The structural design is ingenious and reasonable, and it is easy to use; 2) In this device, a trapezoidal expansion part is set inside the blanking barrel, through which the lighting device and the camera recognition device can be installed correspondingly without affecting the blanking of the material, and the structure is reasonably set; 3) The device is reasonably equipped with a separation cylinder plate at the lower end of the drop cylinder.

DETAILED DESCRIPTION

[0016] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0017] like Figure 1 and Figure 2 As shown, a drop-type weed seed automatic sorting device comprises a storage bin 1 located at the top layer, a drop-out barrel 2 extending vertically downward is arranged at the bottom of the storage bin 1, the drop-out barrel 2 is a rectangular cylinder structure, a feed inlet is arranged at the upper end of the drop-out barrel 2, a discharge outlet is arranged at the lower end, and a receiving frame 3 is arranged below the discharge outlet; An outwardly extending portion 4 is provided at the middle of the blanking barrel 2, and a lighting device 5 and a camera identification device 6 for identifying weed seeds are installed on the side walls of the outwardly extending portion 4; when the material enters the blanking barrel 2 from the feeding port and falls into the blanking barrel 2, the camera identification device 6 takes a picture of the material and identifies the weed seeds accordingly under the illumination of the lighting device 5 when the material passes through the outwardly extending portion 4; like Figure 3 and Figure 4 As shown, two separation barrel plates 7 are further provided at the lower end of the blanking barrel 2, and the two separation barrel plates 7 are hingedly installed through hinges 8, and a push mechanism 9 is respectively installed on the left and right sides of the two separation barrel plates 7, and the main shafts of the push mechanisms 9 on both sides are respectively installed on the separation barrel plates 7 through hinges 8. Under the action of the push mechanisms 9 on both sides, the two separation barrel plates 7 are tilted to the left at the same time, and a sorting frame 10 is correspondingly provided below the two separation barrel plates 7; When the camera recognition device 6 recognizes that weed seeds are mixed in the falling material, the pushing mechanisms 9 on both sides are opened accordingly, and the two separation barrel plates 7 are tilted to the left, so that the falling direction of the material in the drop barrel 2 changes, and the material falls to the left into the sorting frame 10. This part of the material is mixed with weed seeds. After that, the two separation barrel plates 7 are reset by the pushing mechanism 9, and the material falls normally into the receiving frame 3.

[0018] The bottom of the storage bin 1 is configured as a funnel-shaped structure, and the blanking barrel 2 is disposed at the bottom of the storage bin 1 ; a vibration motor 11 is also installed on the storage bin 1 , and the material in the blanking barrel 2 is vibrated by the vibration motor 11 .

[0019] The internal dimensions of the blanking barrel 2 are set accordingly so that only one layer of material enters the blanking barrel 2 at a time, and the material does not pile up in the blanking barrel 2 .

[0020] The outer expansion part 4 is a trapezoidal structure as a whole, and the materials will fall down accordingly after falling into the outer expansion part 4.

[0021] The blanking barrel 2 is provided with fixed plates 12 on both sides and separation barrel plates 7 on both sides. The separation barrel plates 7 are hingedly installed correspondingly through hinges 8, and the two separation barrel plates 7 are tilted correspondingly between the fixed plates 12 on both sides.

[0022] The two push mechanisms 9 connected to the two separation barrel plates 7 are in a synchronous driving form, the push mechanism 9 on the left is set in a retracting form, and the push mechanism 9 on the right is set in a pushing form; the receiving frame 3 and the sorting frame 10 are of the same size.

[0023] The specific working of the technical scheme of this device is as follows: the material in the storage bin falls from the blanking barrel under the action of the vibration motor, and the thickness of the material in the blanking barrel is set accordingly so that the thickness of the blanking material will not cause serious stacking, otherwise it will cause inaccurate identification.

[0024] In the process of material falling downward, an outward expansion part is correspondingly provided at the side wall of the drop barrel. The outward expansion part will not affect the falling of the material, and a lighting device and a camera recognition device are correspondingly installed in the outward expansion part. In the process of material falling downward, the material is illuminated by the lighting device and recognized by the camera recognition device. Usually, the color of weed seeds is obviously different from that of grain materials, so they can be identified and distinguished by color. This is a relatively common technology in the field of weed seed recognition technology in the prior art, so its specific principle is not explained in detail.

[0025] When weed seeds are identified, the pushing mechanisms on both sides are opened accordingly, causing the separation cylinder plate to tilt to the left. At this time, the material will change direction and fall from the position of the left separation cylinder plate into the sorting frame below. This part of the material is mixed with weed seeds. After that, the pushing mechanism quickly restores the separation cylinder plate to its original position, and the material falls into the receiving frame normally.

[0026] After the weed seeds fall into the sorting frame, they can be manually sorted out very conveniently; and in the above sorting process, the specific structural setting of the blanking barrel is also very important. The lower end of the blanking barrel is installed with a separation barrel plate through a hinge, so that the separation barrel plate can be moved driven by the pushing mechanism on the left and right sides, thereby forming an inclined manner, and in order to further smoothly drop the material, a sealing film can be correspondingly installed between the two separation barrel plates to block and seal the side parts of the two separation barrel plates. When the material turns, the material will be discharged more smoothly and conveniently.

[0027] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
