Description

Technical Field

[0001] The invention relates to the technical field of seeding, and in particular to an air suction counting seeding device and method. Background Art

[0002] Seed-feeding is mostly used in the sowing and seed testing industries. It refers to sending seeds one by one or in batches through mechanical mechanisms. When sowing, the seeds are sent out one by one through the seed-feeding device and sown into the soil; when testing seeds, the seeds are separated into individual grains through the seed-feeding equipment to achieve seed-by-seed testing.

[0003] At present, the structural forms of seeding devices mainly include pneumatic, mechanical, electromagnetic vibration, etc. The pneumatic precision seeder uses a negative pressure generator to generate negative pressure to absorb seeds. The seeder has no strict requirements on the shape of the seeds and has high seeding accuracy, but the overall structure is complex, the manufacturing cost and technical requirements for use are high, and the pores are easily blocked. The mechanical precision seeder uses sockets, shaped holes, etc. to seed. It has a simple structure, low seeding accuracy, a relatively single sowing form, and there is a phenomenon of seed damage. It is also difficult to achieve precise seeding for seeds with irregular shapes or small particles. The electromagnetic vibration precision seeder uses electromagnetic vibration to sort seeds. The vibrating plate of the seeder is driven by an electromagnet to vibrate. The seeds flowing out of the vibration box move along the trapezoidal grooves set on the seeding disk, and move forward evenly and fall into the seed delivery tube, and then are introduced into the hole by the seed delivery tube. This seeding method can adapt to seeds of various shapes, but the single seed precision sowing rate is low and the reseeding rate is high. It is more suitable for row sowing.

[0004] In summary, the seeding device described above has relatively low seeding efficiency and accuracy when performing seeding by seed, and it is difficult to realize batch counting seeding, which makes it difficult to improve the efficiency of seed detection by seed. Summary of the invention

[0008] Wherein, the negative pressure suction device comprises an air pump and an air chamber, the suction end of the air pump is connected to the air chamber, and the air chamber is connected to the seed suction tray.

[0009] Wherein, the seed suction plate is detachably sealed and connected to the negative pressure suction device, and the diameter of at least one section of the suction holes is smaller than the diameter of the seeds to be tested.

[0010] The shape of one end of the air suction hole close to the adsorption disk surface is adapted to the shape of the seed to be tested, and the aperture of one end of the air suction hole away from the adsorption disk surface is smaller than the diameter of the seed to be tested.

[0011] The suction holes are arranged on the adsorption disk in any of an array, a spiral, and a circular radial shape.

[0012] Among them, the transfer mechanism includes a vertical lifting mechanism, a transverse movement mechanism and a transverse movement guide rail; the vertical lifting mechanism is connected to the seed adsorption mechanism, the vertical lifting mechanism is connected to the transverse movement mechanism, the transverse movement mechanism is slidably installed on the transverse movement guide rail, and the hopper and the seeding platform are arranged along the transverse movement guide rail.

[0013] Wherein, the diameter of the hopper gradually decreases from top to bottom.

[0014] An embodiment of the present invention also provides a seeding method based on the air suction counting seeding device as described above, comprising: S1, pouring the seeds to be tested into a hopper; S2, starting the negative pressure suction device, moving the seed suction tray into the hopper, and controlling the seed suction tray to move back and forth in the hopper, and after a stable negative pressure is formed in the seed suction tray, moving the seed suction tray out of the hopper; S3, moving the seed suction tray from the hopper to the upper side of the seeding platform, placing the adsorption disk surface of the seed suction tray parallel to the seeding platform, and closing the negative pressure suction device.

[0015] It also includes: using a conveyor belt of a belt conveyor mechanism to arrange the seeds to be tested; after the seed suction disc releases the seeds to be tested to the belt conveyor mechanism, the conveyor belt conveys a preset distance along its conveying direction; at the same time, the seed suction disc resets to the hopper to count and seed the seeds to be tested for the next time.

[0016] The above one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0017] The air suction counting seeding device and method provided in the embodiment of the present invention can absorb the seeds to be tested from the hopper through the seed adsorption mechanism, and can automatically arrange a preset number of batched seeds to be tested grain by grain while adsorbing the seeds to be tested. When the seed adsorption mechanism is transferred from the hopper to the seeding platform through the transfer mechanism, the seeds to be tested adsorbed by the seed adsorption mechanism can be directly released onto the seeding platform, so that the preset number of seeds to be tested can be automatically arranged grain by grain in batches on the seeding platform.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figure 1 The present embodiment provides an air suction counting seeding device, comprising: a hopper 1, a seed adsorption mechanism 2, a transfer mechanism 3 and a seeding platform 4; the seed adsorption mechanism 2 is used to adsorb a preset number of seeds to be tested from the hopper 1, and arrange the seeds to be tested one by one into a preset shape; the transfer mechanism 3 is connected to the seed adsorption mechanism 2, and is used to transfer the seed adsorption mechanism 2 from the hopper 1 to the seeding platform 4; the seeding platform 4 is used to arrange the seeds to be tested adsorbed by the seed adsorption mechanism 2.

[0028] Specifically, the air suction counting seeding device shown in this embodiment absorbs the seeds to be tested from the hopper 1 through the seed adsorption mechanism 2, and can automatically arrange a preset number of batched seeds to be tested grain by grain while adsorbing the seeds to be tested. When the seed adsorption mechanism 2 is transferred from the hopper 1 to the seeding platform 4 through the transfer mechanism 3, the seeds to be tested adsorbed by the seed adsorption mechanism 2 can be directly released onto the seeding platform 4, so that the preset number of seeds to be tested are automatically arranged grain by grain in batches on the seeding platform 4.

[0029] The solution shown in this embodiment is not only easy to operate and low in cost, but also ensures seeding efficiency and accuracy, realizes batch counting and seeding of seeds to be tested, and is convenient for improving the efficiency of grain-by-grain detection of seeds to be tested.

[0030] Preferably, the seed adsorption mechanism 2 shown in this embodiment can be understood as a corresponding structure that can automatically arrange a preset number of batches of seeds to be tested one by one while adsorbing the seeds to be tested based on negative pressure.

[0031] like Figure 3As shown, in one specific embodiment, the seed adsorption mechanism 2 may include: a seed suction disc 23 and a negative pressure suction device; the negative pressure suction device is connected to the seed suction disc 23, and the seed suction disc 23 includes an adsorption disc surface 231, and a plurality of suction holes 232 are provided on the adsorption disc surface 231. In this way, the number of suction holes 232 on the adsorption disc surface 231 and their arrangement form may be set accordingly, so that each time the adsorption of the seeds to be tested is performed, the number of adsorbed seeds to be tested may be automatically obtained, and it is ensured that the adsorbed seeds are arranged in a preset shape of grain by grain. Among them, the shape of the arrangement of the suction holes 232 on the adsorption disc surface 231 includes any one of an array shape, a spiral line shape, and a circular radial shape, which is not specifically limited here.

[0032] like Figure 3 As shown, in order to ensure the continuous arrangement of the seeds to be tested on the seeding platform 4, the shape of the arrangement of the suction holes 232 on the adsorption disk 231 is preferably an array shape. Figure 1 As shown, the seed discharging platform 4 can be preferably a belt conveyor mechanism, and accordingly, the seeds to be tested released by the seed suction disc 23 are arranged in an array on the conveyor belt of the belt conveyor mechanism, so that each time after the seed suction disc 23 releases the seeds to be tested to the belt conveyor mechanism, the conveyor belt of the belt conveyor mechanism can be controlled to convey a preset distance along its conveying direction, and the preset distance can be the length of the seeds to be tested arranged along the transmission direction of the conveyor belt; at the same time, the seed suction disc 23 can also be controlled to return to the hopper 1 to perform the next counting and discharging of the seeds to be tested, so that the seeds to be tested can be counted and discharging continuously in batches.

[0033] Preferably, if Figure 2 As shown, the negative pressure suction device in this embodiment includes an air pump 21 and an air chamber 22, the air suction end of the air pump 21 is connected to the air chamber 22, and the air chamber 22 is connected to the seed suction disc 23. Among them, the air pump 21, the air chamber 22 and the seed suction disc 23 are arranged in sequence from top to bottom, the seed suction disc 23 is in a box shape, the air pump 21 is connected to the upper end of the air chamber 22, the lower end of the air chamber 22 is connected to the upper end of the seed suction disc 23, and the lower end surface of the seed suction disc 23 is set as the adsorption disc surface 231 shown in the above embodiment. In this way, it is convenient for the air pump 21 to perform negative pressure air extraction on the seed suction disc 23 through the air chamber 22, ensuring the consistency of the air pressure at each air suction hole 232 on the adsorption disc surface 231, and based on the adsorption disc surface 231, the seeds to be tested loaded in the hopper 1 can be fully contacted and adsorbed.

[0034] Here, the diameter of the hopper 1 can also be set to gradually decrease from top to bottom, and when the seed suction tray 23 is rectangular, the cross-section of the hopper 1 along the vertical direction can be further set to be an inverted isosceles trapezoid. Of course, when the seed suction tray 23 is circular, the cross-section of the hopper 1 along the horizontal direction can be correspondingly set to be circular, so as to facilitate the seed suction tray 23 to move without dead angles in the hopper 1.

[0035] In one of the preferred embodiments, in order to realize batch counting and seeding of different types of seeds, a seed suction tray 23 can be provided with a detachable sealed connection with a negative pressure suction device, that is, the upper end of the seed suction tray 23 and the lower end of the air chamber 22 can be detachably sealed and connected.

[0036] At the same time, in order to ensure that only one seed to be tested is adsorbed in each air suction hole 232 to ensure the accuracy of batch seeding, the air suction hole 232 in this embodiment can be designed to have at least one section of the aperture smaller than the diameter of the seed to be tested, and the shape of the end of the air suction hole 232 close to the adsorption disk surface 231 is specifically designed to be compatible with the shape of the seed to be tested, and the aperture of the end of the air suction hole 232 away from the adsorption disk surface 231 is smaller than the diameter of the seed to be tested, thereby not only ensuring the batch seeding of the seeds to be tested, but also effectively preventing the seeds to be tested from falling during the process of transferring the seed suction disk 23 from the hopper 1 to the seeding platform 4.

[0037] Based on the further improvement of the above embodiment, the transfer mechanism 3 shown in this embodiment can be a two-axis, three-axis or other multi-axis mechanical arm known in the art. The transfer mechanism 3 can also specifically include a vertical lifting mechanism, a transverse movement mechanism and a transverse movement guide rail 31; the vertical lifting mechanism can be connected to the seed adsorption mechanism 2, and the vertical lifting mechanism drives the seed adsorption mechanism 2 to perform lifting and lowering movements in the vertical direction; because the vertical lifting mechanism is connected to the transverse movement mechanism, the transverse movement mechanism is slidably installed on the transverse movement guide rail 31, so that when the transverse movement mechanism moves laterally along the transverse movement guide rail 31, the seed adsorption mechanism 2 can move laterally accordingly. In this way, the hopper 1 and the seeding platform 4 can be arranged along the transverse movement guide rail 31, so that based on the transfer mechanism 3, the seed adsorption mechanism 2 can be transferred from the hopper 1 to the seeding platform 4.

[0038] like Figure 1 and Figure 2 As shown, in one specific embodiment, two transverse guide rails 31 are provided and arranged side by side, the seed adsorption mechanism 2 is arranged between the two transverse guide rails 31, and the vertical lifting mechanism can be composed of a vertical driving mechanism 34 and a vertical guiding mechanism 35 which are arranged on opposite sides of the seed adsorption mechanism 2, wherein the vertical driving mechanism 34 includes a first driving motor and a screw rod, the first driving motor is installed on the first support 32, the output end of the first driving motor is connected to the screw rod, the screw rod is vertically arranged, and is threadedly connected to the outer wall of the corresponding air chamber 22 on the seed adsorption mechanism 2, and the vertical guiding mechanism 35 includes a vertical guiding rod installed on the second support 33, and the vertical guiding rod is slidingly connected to the outer wall of the corresponding air chamber 22 on the seed adsorption mechanism 2.

[0039] Correspondingly, the transverse movement mechanism includes an active transverse movement mechanism 36 and a driven transverse movement mechanism 37, wherein the active transverse movement mechanism 36 includes a second drive motor and a driving wheel, the second drive motor is installed on the first support 32, the output end of the second drive motor is connected to the driving wheel, and the driving wheel can move along the guide groove on one of the transverse guide rails 31, and the driven transverse movement mechanism 37 includes a driven wheel, which is installed on the second support 33 through a short shaft, and the driven wheel can move along the guide groove on the other transverse guide rail 31.

[0040] like Figure 4 As shown, the present embodiment also provides a seeding method based on the air suction counting seeding device as described above, comprising: S1, pouring the seeds to be tested into the hopper; S2, starting the negative pressure suction device, moving the seed suction tray into the hopper, and controlling the seed suction tray to move back and forth in the hopper, and after a stable negative pressure is formed in the seed suction tray, moving the seed suction tray out of the hopper; S3, moving the seed suction tray from the hopper to the upper side of the seeding platform, and placing the adsorption disk surface of the seed suction tray parallel to the seeding platform, and closing the negative pressure suction device.

[0041] Specifically, when counting and sowing seeds one by one, the operation steps are as follows:

[0042] First, pour the seeds to be tested into the hopper.

[0043] Then, start the air pump, and the air pump evacuates the air holes on the seed suction tray through the air chamber, so that negative pressure is formed in the seed suction tray and an airflow for suction is generated at the air suction holes to adsorb the seeds to be tested. At the same time, start the vertical lifting mechanism to move the seed suction tray vertically downward until the adsorption disk surface at the lower end of the seed suction tray is close to the seeds to be tested in the hopper. By controlling the horizontal reciprocating movement of the seed suction tray in the hopper, it can be ensured that each air suction hole has a sufficient chance to adsorb the seeds to be tested, so that when a stable negative pressure is formed in the seed suction tray, it is ensured that a seed to be tested is adsorbed in each air suction hole. At this time, it is only necessary to control the seed suction tray to move out of the hopper through the vertical lifting mechanism.

[0044] Next, the seed suction tray is driven by the transverse movement mechanism to move along the transverse movement guide rail to the upper side of the belt conveyor mechanism, and the seed suction tray is controlled to move downward by the vertical lifting mechanism until the adsorption disk surface of the seed suction tray is parallel to the seed dispensing platform, and then the air pump is turned off to release the seeds to be tested adsorbed by the seed suction tray to the conveyor belt of the belt conveyor mechanism. Here, the seed suction tray is controlled by the transfer mechanism to reset to the hopper to count and discharge the seeds to be tested next time. At the same time, the conveyor belt of the belt conveyor mechanism conveys a preset distance along its conveying direction, and operates in sequence in this way to form a seed array on the conveyor belt of the belt conveyor mechanism, and the seed array is arranged along the conveying direction of the conveyor belt.

[0045] It should be pointed out here that in this embodiment, suction holes arranged in a square array can be set on the adsorption disk surface of the seed suction disk. For example, the square array can be a 10*10 array, so that 100 seeds to be tested can be adsorbed on the adsorption disk surface of the seed suction disk at one time, so that the seed suction disk counts the number of seeds to be discharged while discharging seeds, and the final number of seeds to be tested is the product of the number of adsorption times of the seed suction disk and 100. Of course, the array of suction holes can also be designed as an n*m array according to actual needs, where n and m are both natural numbers greater than 1, thereby completing the counting and discharging of seeds to be tested in different batches.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
