DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 10The garlic sowing device of the embodiment of the present invention comprises: a frame 100, a seeding unit 200 and a sowing unit 300, the seeding unit 200 comprises a first seed box 1, a first seed taking component 2 and a seed adjustment component 3, the first seed box 1 is installed on the frame 100, the first seed taking component 2 passes through the first seed box 1 to take out the garlic seeds in the first seed box 1, the seed adjustment component 3 is located outside the first seed box 1, in the seed conveying direction, the seed adjustment component 3 is located downstream of the first seed taking component 2, the seed adjustment component 3 is used to adjust the direction of the garlic seeds on the first seed taking component 2, the sowing unit 300 is connected to the frame 100, in the seed conveying direction, the sowing unit 300 is located downstream of the seeding unit 200, and the sowing unit 300 sows the garlic seeds conveyed by the first seed taking component 2 into the soil.

[0034] Specifically, Figures 1 to 3 As shown, the frame 100 has a cavity inside, the seeding unit 200 is installed in the cavity, the first seed box 1 is fixed in the cavity inside the frame 100, the first seed taking component 2 at least partially penetrates into the first seed box 1, the first seed taking component 2 can take out the garlic seeds in the first seed box 1, and the seed adjustment component 3 can adjust the direction of the garlic seeds taken out by the first seed taking component 2 to ensure that the garlic seed bulbs are facing upward, thereby improving the sowing quality and increasing the garlic yield.

[0035] The sowing unit 300 is located downstream of the first seed taking component 2, that is, the garlic seeds discharged by the first seed taking component 2 enter the sowing unit 300, and the sowing unit 300 is used to sow the garlic seeds into the soil.

[0036] Optionally, a walking wheel 12 and a suppressing wheel 13 are also provided on the frame 100. The walking wheel 12 is located at the front end of the sowing unit 300, and the suppressing wheel 13 is located at the rear end of the sowing unit 300. In other words, in the direction of movement of the frame 100, the walking wheel 12 is located upstream of the sowing unit 300, and the suppressing wheel 13 is located downstream of the sowing unit 300.

[0037] The garlic sowing device of the embodiment of the present invention can realize the seeding of single-clove garlic seeds by using the first seed taking component 2, and can adjust the direction of the garlic seeds by using the seed adjustment component 3 to ensure that the bulbs of the garlic seeds face upward, thereby improving the planting quality and garlic yield.

[0038] In some embodiments, the first seed taking component 2 includes a first seed taking chain 21, multiple first seed taking spoons 22 and a seed discharging tube 23. The multiple first seed taking spoons 22 are evenly spaced along the extension direction of the first seed taking chain 21. The first seed taking chain 21 includes a seed taking section 211, a conveying section 212 and a seed discharging section 213. The seed taking section 211 passes through the first seed box 1, the conveying section 212 moves from bottom to top, and the seed discharging section 213 moves from top to bottom. The seed discharging section 213 passes through the seed discharging tube 23. The seed discharging tube 23 is arranged obliquely in the up and down directions, and the inlet of the seed discharging tube 23 is connected to the connection between the conveying section 212 and the seed discharging section 213, and the outlet of the seed discharging tube 23 is connected to the sowing unit 300.

[0039] Specifically, Figure 3 As shown, the first seed taking chain 21 is arranged in a ring shape, and the first seed taking chain 21 is driven by a sprocket, and the sprocket is connected to the running wheel 12 through a driving chain. In other words, the running wheel 12 is the power source of the first seed taking chain 21, and the first seed taking chain 21 is divided into a seed taking section 211, a conveying section 212 and a seed discharge section 213. It should be noted that the division of the first seed taking chain 21 is not fixed. Since the chain is always in a moving state, the seed taking section 211 is one end of the chain in the first seed box 1, and the seed taking section 211 moves from bottom to top, the chain of the conveying section 212 moves from back to front, and the seed discharge section 213 moves from top to bottom.

[0040] A plurality of first seed taking spoons 22 are evenly spaced along the extension direction of the first seed taking chain 21, the seeding tube 23 is arranged parallel to the chain of the seeding section 213, and the chain of the seeding section 213 is located in the seeding tube 23, that is, the first seed taking spoon 22 in the seeding tube 23 is located in the seeding tube 23, and the seeding tube 23 is arranged inclined from top to bottom toward the rear end.

[0041] A plurality of first seed taking spoons 22 evenly spaced apart can evenly take out the garlic seeds in the first seed box 1, and the seed discharge tube 23 can ensure that the garlic seeds enter the sowing unit 300 in an orderly manner, avoiding crowding of the garlic seeds in the sowing unit 300 and causing unsmooth sowing, thereby reducing the risk of missed sowing and over-sowing.

[0042] The first seeding chain 21 is used to drive the first seeding spoon 22 to move back and forth, thereby improving the orderly progress of seeding and sowing. The first seeding chain 21 is driven by the walking wheel 12, which can match the seeding, sowing and frame 100 travel speeds and improve the sowing quality.

[0043] In some embodiments, the first seed taking spoon 22 includes a baffle 221 and a spoon body 222, the spoon body 222 is connected to the baffle 221, and the baffle 221 is located below the spoon body 222, and the spoon body 222 has a receiving groove therein, and the receiving groove is used to receive garlic seeds.

[0044] Specifically, Figure 4As shown, the baffle 221 is located at the lower end of the spoon body 222, and the outer contour of the spoon body 222 is generally adapted to the outer contour of the garlic seeds, that is, it is semicircular or crescent-shaped, and one end of the spoon body 222 is open, and the spoon body 222 and the baffle 221 form a storage tank for storing the garlic seeds. The size of the baffle 221 is larger than the size of the spoon body 222, and the internal volume of the spoon body 222 is slightly larger than the volume of the garlic seeds. In other words, the internal volume of the spoon body 222 is larger than the volume of one garlic seed and smaller than the volume of two garlic seeds, ensuring that one spoon body 222 can only take one garlic seed at a time, reducing the risk of multiple sowing.

[0045] It should be noted that, in the seeding section 211 of the first seeding chain 21, the baffle 221 is located at the lower end of the spoon body 222, and in the seeding section 213 of the first seeding chain 21, the baffle 221 is located at the upper end of the spoon body 222. That is, in the conveying section 212 and the seeding section 211, the garlic seeds are located above the baffle 221, and in the seeding section 213, the garlic seeds are on the baffle 221 of the lower first seeding spoon 22 of the two adjacent first seeding spoons 22, and as the first seeding spoon 22 moves downward, the baffle 221 gradually changes to a horizontal orientation, and the garlic seeds placed on the baffle 221 also change to a horizontal orientation.

[0046] In some embodiments, the seed adjustment assembly 3 includes a first detection component 31 and an adjustment component 32. The first detection component 31 is installed in the seed tube 23, and the first detection component 31 is arranged adjacent to the conveying section 212. The first detection component 31 is used to detect the capacitance value of the garlic seeds. The adjustment component 32 is installed adjacent to the outlet of the seed tube 23. The adjustment component 32 includes a first telescopic rod 321 and a second telescopic rod 322. The first telescopic rod 321 and the second telescopic rod 322 are arranged relative to each other in the width direction of the seed tube 23, and the first telescopic rod 321 and the second telescopic rod 322 can extend into or out of the seed tube 23.

[0047] For example, the first detection component 31 is a capacitive identification sensor, and the number of the first detection components 31 is two, and the two first detection components 31 are respectively installed on the left and right sides of the seed tube 23.

[0048] It should be noted that the capacitance recognition sensor is composed of two plates, which are arranged relative to each other in the vertical direction, that is, one capacitance recognition sensor includes two plates symmetrically arranged in the vertical direction. The width of the plate is roughly consistent with the average width of the garlic seeds. The garlic is approximately considered as an insulator. When the garlic seeds approach the first detection component 31 from top to bottom in a horizontal state, when the garlic seeds have not yet entered the sensing distance of the first detection component 31, the medium between the electrode on the left side of the first detection component 31 and the electrode on the right side of the first detection component 31 is air, a seed spoon and a chain. At this time, the capacitance value measured by the first detection component 31 is C0. When the garlic seeds pass through the sensing range of the first detection component 31, the specific gravity of the garlic seeds increases first and then decreases, causing the average equivalent dielectric constant in the sensor detection area to increase first and then decrease, and the capacitance value between the two plates to increase first and then decrease.

[0049] Since the head (bulb end) of garlic seeds is smaller than the tail, the proportion of the head in the detection area is smaller than that of the tail, resulting in the equivalent dielectric constant of the head in the detection area being smaller than that of the tail. Therefore, according to the formula .in is the equivalent dielectric constant of air and garlic, is the absolute dielectric constant of vacuum, is the first kind of elliptic integral. The measured capacitance C of the bulb end 芽 must be smaller than the tail capacitance C 尾 The processor compares the capacitance values ​​measured by the first detection components 31 on the left and right sides to determine the direction of the bulb end of the garlic seed.

[0050] Specifically, Figure 5 As shown, the adjustment component 32 is located downstream of the first detection component 31, that is, the garlic seeds first pass through the first detection component 31 and then pass through the adjustment component 32. The adjustment component 32 includes a first telescopic rod 321 and a second telescopic rod 322, which are symmetrically arranged in the left-right direction, and the fixed ends of the first telescopic rod 321 and the second telescopic rod 322 are outside the seeding tube 23, and the telescopic ends of the first telescopic rod 321 and the second telescopic rod 322 can extend into or out of the seeding tube 23.

[0051] It should be noted that one of the first telescopic rod 321 and the second telescopic rod 322 extends into the seed tube 23, that is, when the garlic seed bulbs are facing to the right, the telescopic end of the first telescopic rod 321 withdraws from the seed tube 23, and the telescopic end of the second telescopic rod 322 extends into the seed tube 23; when the garlic seed bulbs are facing to the left, the first telescopic rod 321 extends into the seed tube 23, and the telescopic end of the second telescopic rod 322 withdraws from the seed tube 23.

[0052] The garlic sowing device of the embodiment of the present invention can detect the direction of the garlic seeds by using the first detection component 31, and can adjust the direction of the garlic seeds by using the adjustment component 32, thereby improving the quality of garlic seed sowing.

[0053] In some embodiments, the garlic sowing device also includes a reseeding unit 400, which includes a reseeding tube 4 and a third telescopic rod 5. The reseeding tube 4 is connected to the seeding tube 23, and the third telescopic rod 5 is located at the connection between the reseeding tube 4 and the seeding tube 23, and the third telescopic rod 5 can be extended into or out of the reseeding tube 4.

[0054] Specifically, Figure 6As shown, the reseeding tube 4 is arranged from top to bottom and tilted backward, and is arranged parallel to the seeding tube 23. Garlic seeds are pre-stored inside the reseeding tube 4. When the first detection component 31 detects that there is a phenomenon of missed seeds, the garlic seeds in the reseeding tube 4 are pushed into the position where the seeds are missed in the seeding tube 23 through the third telescopic rod 5, thereby reducing the risk of missed seeds.

[0055] In some embodiments, the sowing unit 300 includes a buffer tray 6 and a sowing component 7. The buffer tray 6 is connected to the frame 100 and is rotatable relative to the frame 100. A plurality of buffer holes 61 are provided on the buffer tray 6. The plurality of buffer holes are arranged at intervals along the circumference of the buffer tray 6. The sowing component 7 includes a sowing tube 71 and a duckbill 72. The duckbill 72 is located at the outlet of the sowing tube 71 to open or close the outlet of the sowing tube 71. The inlet of the sowing tube 71 is selectively connected to one of the buffer holes. The sowing tube 71 is movable in the up and down directions to allow the duckbill 72 to be inserted into or pulled out of the soil.

[0056] Specifically, Figure 7 As shown, the buffer tray 6 is installed at the outlet of the seed discharging tube 23. The buffer tray 6 is connected to the frame 100 through a pivot shaft, and a gap smaller than the length of the garlic seeds is retained between the bottom of the buffer tray 6 and the bottom shell of the frame 100 to prevent the garlic seeds from falling from the buffer cavity.

[0057] The outer sleeve of the sowing tube 71 is provided with an elastic member 74, for example, the elastic member 74 is a spring, the upper end of the sowing tube 71 has a positioning plate, the upper end of the elastic member 74 abuts against the positioning plate, and the lower end of the elastic member 74 abuts against a support frame 73 fixed on the frame 100. A cam 75 mechanism is installed on the side of the sowing tube 71, and the cam 75 can drive the sowing tube 71 to move downward and cooperate with the elastic member 74 to realize the up and down reciprocating motion of the sowing tube 71.

[0058] An upper limit rod 76 and a lower limit rod 77 are respectively installed on the upper and lower sides of the duckbill 72. When the duckbill 72 contacts the lower limit rod 77, the duckbill 72 will open. Conversely, when the duckbill 72 contacts the upper limit rod 76, the duckbill 72 will close.

[0059] It should be noted that when the buffer disk rotates, one of the buffer holes is aligned with the inlet of the sowing tube 71. The garlic seeds in the buffer hole 61 will fall into the sowing tube 71 without the obstruction of the bottom shell of the frame 100. As the cam 75 drives the sowing tube 71 to move downward, the duckbill 72 is inserted into the soil, and the garlic seeds in the sowing tube 71 are then sown into the soil.

[0060] In some embodiments, the garlic seeding device further includes a screening unit 500. The screening unit 500 includes a second seed box 8, a second seed-taking component 9, and a second detection component 10. The second seed box 8 is connected to the frame 100 and is arranged at an interval with the first seed box 1. The second seed-taking component 9 partially penetrates into the second seed box 8 to take out the garlic seeds in the second seed box 8. The second detection component 10 is used to detect the capacitance value of the garlic seeds on the second seed-taking component 9.

[0061] Specifically, as Figure 1 and Fig. 9 shown, the second seed box 8 is installed in the frame 100 and is arranged at an interval with the first seed box 1 in the front-back direction. It should be noted that there are good seeds and inferior seeds in the second seed box 8. Therefore, it is necessary to use the second detection component 10 to detect the inferior seeds and remove them.

[0062] The structure of the second seed-taking component 9 is the same as that of the first seed-taking component 2. The second seed-taking component 9 includes a second seed-taking chain 91 and a plurality of second seed-taking spoons 92. The plurality of second seed-taking spoons 92 are evenly arranged at intervals along the extending direction of the second seed-taking chain 91. The second detection component 10 is a ring capacitance sensor, and the capacitance value of the garlic seeds can be detected by using the second detection component 10.

[0063] It should be noted that the chain in the second seed-taking component 9 is driven by a sprocket. The second seed-taking spoons 92 are evenly distributed on the chain. The second seed-taking spoons 92 scoop up the garlic seeds in the second seed box 8. The garlic seeds enter the seed spoons under the action of their own gravity and the interaction force of other garlic seeds. The second seed-taking spoons 92 lift the garlic seeds from bottom to top, and the capacitance value of the taken garlic seeds is detected through the second detection component 10. The maximum capacitance value within a period of time is obtained through an algorithm, and the maximum value Cdet is compared with the calibrated capacitance value Cstd of the normal garlic seeds. When Cdet < Cstd, the garlic seeds are inferior seeds, and a signal is transmitted to the removal component to perform the removal action.

[0064] By setting the second detection component 10, the capacitance value of the garlic seeds can be detected, and the garlic seeds that do not meet the seeding requirements can be removed, improving the seeding quality.

[0065] In some embodiments, the screening unit 500 further includes a removal component. The removal component is located between the second seed box 8 and the first seed box 1. The removal component includes a conveying plate 141, a removal plate 142, and a third seed box 11. The conveying plate communicates with the first seed box 1 and the second seed box 8. The conveying plate is provided with a removal opening. The removal plate is pivotally connected to the conveying plate, and the removal plate can open or close the removal opening. The third seed box 11 communicates with the removal opening.

[0066] Specifically, as Fig.10As shown in the figure, the conveying plate is arranged obliquely from back to front and from top to bottom. Both ends of the conveying plate are connected to the first type of box 1 and the second type of box 8. There is a rejection opening in the middle of the conveying plate. One end of the rejection plate is pivotally connected to the conveying plate through a pin shaft, and a torsion spring is sleeved on the pin shaft. When there is no rejection action, the rejection plate fits with the conveying plate under the action of the torsion spring, and the rejection opening is closed. Good seeds enter the first type of box 1 through the conveying plate. When the rejection action is performed, the rejection plate rotates around the pin shaft, and the substandard seeds slide out of the seed groove along the surface of the rejection plate and fall into the third type of box 11.

[0067] As Figures 10 to 14 shown, the garlic sowing method according to the embodiment of the present invention includes the following steps: S100. Calibrate the capacitance value of qualified garlic seeds.

[0068] It should be noted that at the beginning of planting, several garlic seeds of uniform size and plumpness are selected and added to the seed box. The capacitance values of several garlic seeds of uniform size and plumpness are collected and averaged, and calibrated as the capacitance value C standard of normal garlic seeds.

[0069] S200. Judge the capacitance value of the garlic seeds in the second type of box 8. If it meets the first preset condition, the garlic seeds in the second type of box 8 are conveyed to the first type of box 1.

[0070] As Fig.13 shown, the first preset condition is C inspection ≥ C standard. The maximum capacitance value within the passing time period is obtained through an algorithm, and the maximum value C inspection is compared with the calibrated capacitance value C standard of normal garlic seeds. When C inspection < C standard, the garlic seeds are substandard seeds, and a signal is transmitted to the rejection component to perform the rejection action.

[0071] S300. Collect the first capacitance value in the idle first seed-taking spoon 22.

[0072] As Fig.13 shown, when the garlic seeds have not entered the sensing distance of the first detection component 31, the medium between the electrodes on the first detection component 31 on the left and the electrodes on the first detection component 31 on the right is air, the seed spoon and the chain. At this time, the first capacitance value measured by the first detection component 31 is C0.

[0073] It should be noted that when the first detection component 31 does not recognize the garlic seeds, it proves that there are no garlic seeds at this position. Then the missing seed information is sent to the processor, and the processor sends an instruction to the third telescopic rod 5 to补种 at this position.

[0074] The distance between the first detection component 31 and the replanting window is 15.24 cm. The calculated time required for the missed seed spoon to move to the replanting position is 1.8 seconds, which meets the processor signal transmission time. The replanting process should start after the missed seed spoon is parallel to the lower end of the replanting window and end before the next seed spoon moves to the upper end of the replanting window. The calculated time window is 0.23 seconds. It takes 0.2 seconds for the third telescopic rod 5 to complete the replanting action. Therefore, the replanting work at all working speeds of the seeder is met.

[0075] S400, collecting the second capacitance value and the third capacitance value of the garlic detected by the first detection component, determining whether the second capacitance value and the first capacitance value, as well as the third capacitance value and the first capacitance value, meet a second preset condition, and if so, comparing the second capacitance value and the third capacitance value. It should be noted that the capacitance value detected by the first detection component 31 on the left side is the second capacitance value C 左 , the capacitance value detected by the first detection component 31 on the right side is the third capacitance value C 右 .

[0076] S500 , selectively driving the first telescopic rod 321 and the second telescopic rod 322 according to the ratio between the second capacitance value and the third capacitance value.

[0077] Specifically, when C 右 >C 左 When the bulb of garlic seed is facing right, the telescopic end of the second telescopic rod 322 extends into the seeding tube 23. On the contrary, when C 右 <C 左 When the bulb buds of the garlic seeds are facing the left side, the telescopic end of the first telescopic rod 321 extends into the seed discharging tube 23.

[0078] It should be noted that the forward speed range v of common garlic planters is 0.06 to 0.14 m / s. The spacing between garlic seeding plants should be 10 cm. The spacing between seed spoons is 6 cm. According to calculations, the actual linear speed of the seed spoon is 0.036 m / s to 0.084 m / s. The detection width is two garlic seed widths, i.e. 5 cm. When the seed spoon runs at the fastest linear speed. The sensor detection time is 0.59 seconds. Conventional capacitive sensors can perform hundreds of detections in one second. Therefore, it meets the direction recognition and detection work of the planter at all working speeds.

[0079] S600, the garlic seeds discharged from the seed discharging tube 23 are sown into the soil by using the sowing unit 300.

[0080] It should be noted that the garlic seeds that have completed the orientation adjustment fall into the cache holes 61 on the cache disk with the scales facing upward. The cache holes 61 are evenly distributed along the circumference of the cache disk. The upper ends of the cache holes 61 are chamfered and rounded to ensure that the garlic seeds fall smoothly into the cache holes 61. The size of the cache holes 61 is set according to the average width and thickness of the garlic seeds to ensure that the upright posture of the garlic seeds in the temporary storage holes does not change. The cache disk rotates driven by the central axis and continuously receives the fallen garlic seeds. When the cache holes 61 rotate to coincide with the holes on the frame 100, the garlic seeds fall into the sowing tube 71 below.

[0081] When the garlic seeds fall in, the sowing tube 71 moves upward due to the upward elastic force of the spring. During the upward movement of the duckbill 72 and the sowing tube 71, the duckbill 72 lever is acted upon by the upper limit rod 76 to close the duckbill 72 and stop the sowing tube 71. After the garlic seeds fall into the duckbill 72, the cam 75 rotates and presses down the sowing tube 71 to make the sowing tube 71 and the duckbill 72 move downward. After the duckbill 72 is inserted into the soil to insert the oriented garlic seeds into the soil in a vertical posture, the duckbill 72 levers on both sides are acted upon by the lower limit rod 77 to open the duckbill 72 on both sides, and the soil flows in from the gaps on both sides to surround and bury the garlic in an upright posture. After the upright sowing of the garlic is completed, the sowing tube 71 moves upward due to the elastic force of the spring, and the duckbill 72 is unearthed to enter the next sowing cycle.

[0082] In some embodiments, the garlic sowing method further comprises: S700, calculating the real-time linear speeds of the first seed taking spoon 22 and the second seed taking spoon 92.

[0083] S800 , adjusting the response time of the seed adjustment component 3 , the reseeding unit 400 , and the rejection component 14 according to the real-time linear speed of the first seed taking spoon 22 and the second seed taking spoon 92 .

[0084] Specifically, Fig.13 and Fig.14As shown, the speed of the frame 100 is not absolutely constant during the process of traveling, and the power of the first seed taking component 2 and the second seed taking component 9 is provided by the walking wheel 12. Therefore, the linear speed of the seed taking spoon is not constant. There is a certain distance between the first detection component 31, the second detection component 10 and the reseeding unit 400, the seed adjustment component 3, and the rejection unit. After the first detection component 31 receives the missed seeding signal, the garlic seed orientation signal, and the second detection component 10 detects the sub-seed signal, the corresponding action can be performed after a specific time delay according to the current linear speed of the seed taking spoon. When the capacitance value reaches the peak value, the seed spoon is located in the middle of the two plates. Therefore, the peak value of the capacitance value detected each time is used as a marking point, and the real-time linear speed v of the seed taking spoon can be calculated by the time interval t between the two peaks and the spacing between the seed taking spoons. The distance between each unit is a fixed value s. Therefore, the corresponding response time can be calculated based on the real-time linear speed and the fixed distance. Then the timing module in the post-processor starts timing, and after the timing ends, an action signal is sent to each unit to perform the corresponding action.
