Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pot seedling transplanters, and particularly relates to a self-adaptive pot seedling transplanter with adjustable spacing. BACKGROUND

[0002] A pot seedling transplanter is an automatic device for agricultural production, mainly used for efficiently and accurately transplanting pot seedlings (i.e. seedlings with complete root clumps) in a seedling plug tray to a field. Its core function is to complete the links of seedling taking, conveying and planting through mechanical devices, replacing traditional manual transplanting, significantly improving work efficiency (up to 18-20 times that of manual work), while reducing damage to seedling roots, shortening the seedling period and improving crop survival rate. The device is widely used in large-scale planting of crops such as vegetables, rice and flowers, and plays a significant role in high-replanting-index crops such as leafy vegetables.

[0003] Traditional transplanter spacing adjustment needs to be achieved by replacing sprockets or adjusting the position of mechanical components. For example, the utility model with the patent number CN203661572U discloses a transplanting spacing adjustment device for a transplanter, which comprises a sprocket mechanism I and a sprocket mechanism II. A closed loop chain is sleeved on a corresponding set of sprockets on the sprocket mechanism I and the sprocket mechanism II. An automatic tensioning mechanism is provided on the chain. Through the torsional moment of the tension spring, the tensioning wheel rotates around the tensioning wheel shaft, automatically tensioning the chain. A wheel changing mechanism I is provided on one side of the sprocket mechanism I for adjusting the position of the chain on the sprocket mechanism I. A wheel changing mechanism II is provided on one side of the sprocket mechanism II for adjusting the position of the chain on the sprocket mechanism II. The device simplifies the operation of spacing adjustment, saves adjustment time, and when the transplanter needs to change the transplanting spacing, it does not need to disassemble the drive wheel or change or adjust the relative position of the sprocket, eliminating the cumbersome process of disassembly during spacing adjustment, saving time and effort, and having good use effect.

[0004] The transplanting spacing adjustment device for the transplanter simplifies the chain wheel changing process through the sprocket mechanism and the tension spring, but the operation needs to be stopped and part of the mechanical structure needs to be manually disassembled (such as replacing the sprocket or adjusting the transmission ratio) during the adjustment process. At the same time, the spacing of the pot seedlings cannot be adjusted, and it cannot adapt to self-adaptive pot seedling planting. The above problems will result in low planting efficiency of the device. SUMMARY

[0037] The pot seed holding mechanism 500, see Figure 5 and Figure 10 , including a rotating assembly 510 and a plurality of pot seed holding assemblies 520, the rotating assembly 510 is installed on the moving vehicle body 100, the rotating assembly 510 rotates uniformly at a predetermined speed, a plurality of the pot seed holding assemblies 520 are arranged in a circular array on the rotating assembly 510 at a predetermined interval, and the pot seed holding assemblies 520 are located above the pot seed planting mechanism 400, the pot seed holding assemblies 520 are placed with pot seedlings, and artificial seedling placing is adopted.

[0038] The induction sensing mechanism 600 includes a first sensing assembly 610 and a second sensing assembly 620, the first sensing assembly 610 is arranged on the pot seed holding assembly 520, when the first sensing assembly 610 senses that the duckbill planting assembly 420 is located in the sensing area, that is, the duckbill planting assembly 420 has a first inductor, the first sensing assembly 610 and the first inductor cooperate with each other to sense, the first sensing assembly 610 controls the pot seed holding assembly 520 to open and close the seedling placing, the second sensing assembly 620 is arranged on the rotating assembly 510, the pot seed holding assembly 520 has a second inductor, the second sensing assembly 620 and the second inductor cooperate with each other to sense, when the pot seed holding assembly 520 opens and closes the seedling placing, the second sensing assembly 620 controls the rotating assembly 510 to rotate by a predetermined interval. The first sensing assembly 610 and the second sensing assembly 620 are existing sensing devices, the method of controlling the rotation of the motor by the sensing device is an existing method control, which can realize the rotation of the motor, which will not be described here.

[0039] The movement process includes: By artificial placing pots of seedlings on a plurality of pot seedling containing assemblies 520, the moving vehicle body 100 is started, the driving assembly drives the driving wheel body to move, the driving wheel body drives the driven wheel body to move, the transmission mechanism 200 is in transmission connection with the driven wheel body, and then drives the transmission mechanism 200 to rotate, the transmission mechanism 200 outputs a second rotation speed, and drives the transmission rod mechanism 300 to move. In the process of driving the pot seedling planting mechanism 400 by the transmission rod mechanism 300, it is mainly divided into a seedling collecting process and a seedling planting process; see Figure 7 , the seedling collecting process is that the transmission rod mechanism 300 rotates, drives the vertical swing assembly 410 to swing upward, the vertical swing assembly 410 drives the duck-billed planting assembly 420 to swing upward, the duck-billed planting assembly 420 is in a closed state, when the duck-billed planting assembly 420 approaches the pot seedling containing assembly 520, the first sensor triggers the first sensing assembly 610, the first sensing assembly 610 controls the pot seedling containing assembly 520 to plant seedlings, that is, the pot seedling containing assembly 520 is opened, the pot seedling on the pot seedling containing assembly 520 falls into the duck-billed planting assembly 420, and the pot seedling containing assembly 520 completes the seedling collecting process; see Figure 8 , the seedling planting process is that: in the process of falling of the pot seedling, the second sensor is triggered, the second sensor triggers the second sensing assembly 620, the second sensing assembly 620 controls the rotation assembly 510 to rotate, and stops moving after rotating a preset interval, that is, the pot seedling containing assembly 520 filled with pot seedlings continues to rotate to above the duck-billed planting assembly 420, at the same time, the vertical swing assembly 410 swings vertically downward under the drive of the transmission rod mechanism 300, drives the duck-billed planting assembly 420 to move downward, since the duck-billed planting assembly 420 is away from the pot seedling containing assembly 520, the first sensor cannot sense the first sensor, and therefore the pot seedling containing assembly 520 does not drop the pot seedling, the duck-billed planting assembly 420 moves downward by a preset distance, the transmission rod mechanism 300 drives the duck-billed planting assembly 420 to be in an open state, the pot seedling in the duck-billed planting assembly 420 falls out, and the pot seedling falls into the ground or the furrow, the seedling planting process is completed; and the process is circularly repeated to realize planting of the pot seedling.

[0040] Through the cooperation between the speed change mechanism 200, the transmission rod mechanism 300, the pot seedling planting mechanism 400 and the pot seedling containing mechanism 500, the process of quickly collecting and planting the pot seedlings is realized; and during the planting process, the pot seedlings only need to be placed in the pot seedling containing mechanism 500 by artificial, and do not need to be planted again by artificial, so as to avoid the damage and dispersion of the roots of the pot seedlings; further, by adjusting the speed change mechanism 200, the transmission speed of the transmission rod mechanism 300 is changed, and then the distance between the pot seedlings is adjusted, so as to achieve the self-adaptation of the pot seedling planting; in addition, the self-adaptation pot seedling transplanting machine is an integrated transplanting machine, which does not need to be adjusted by artificial chain wheel and rotating shaft, and does not need to be adjusted by artificial manual transmission ratio, so as to improve the use efficiency of the transplanting machine.

[0041] In a possible embodiment, referring to Figure 6 , the speed change mechanism 200 includes a stepless gearbox 210, a driving pulley 220, an input pulley 230 and an output pulley 240, the stepless gearbox 210 is installed on the mobile vehicle body 100, the stepless gearbox 210 is an existing speed change device, through which the transmission ratio can be changed to change the driving speed and the planting speed of the pot seedlings, the driving pulley 220 is sleeved on the rotating shaft of the mobile vehicle body 100, specifically, the driving pulley 220 is connected with the connecting shaft of the driven pulley body; the input pulley 230 is sleeved on the input shaft of the stepless gearbox 210, and the output pulley 240 is sleeved on the output shaft of the stepless gearbox 210, the driving pulley 220 is connected with the input pulley 230 through a first transmission chain, and the output pulley 240 is connected with the transmission rod mechanism 300 through a second transmission chain. By adjusting the stepless gearbox 210, the transmission ratio is changed, so that the speed of the connecting shaft of the driven pulley body is transmitted to the input pulley 230 through the first transmission chain, and after the transmission ratio of the stepless gearbox 210 is changed, the output of the output shaft of the stepless gearbox 210 is adjusted to a second rotating speed, so that the output pulley 240 is transmitted to the transmission rod mechanism 300 through the second transmission chain; by adjusting the transmission ratio of the stepless gearbox 210, the distance between the pot seedlings planted by the pot seedling planting mechanism 400 is changed, so that the distribution of the sparse degree of the pot seedlings is uniform.

[0042] In a possible embodiment, referring to Figure 6, the transmission rod mechanism 300 comprises a shaft body seat 310, a driving shaft 320, a passive rotating wheel 330 and an eccentric assembly 340, the shaft body seat 310 is provided with a pair, the shaft body seat 310 is installed on the mobile vehicle body 100, the driving shaft 320 is rotatably sleeved to the shaft body seat 310, a pair of shaft body seats 310 can keep the balance of the sleeved driving shaft 320, and prevent the driving shaft 320 from swinging in the rotating process. The passive rotating wheel 330 is arranged at one end of the driving shaft 320, and the passive rotating wheel is connected with the output rotating wheel 240 through the second transmission chain, so that the rotating speed of the output rotating wheel 240 is transmitted to the driving shaft 320.

[0043] Specifically, the shaft body seat 310 is provided with a rotating bearing, when the driving shaft 320 is sleeved on the shaft body seat 310, the driving shaft 320 can rotate in the shaft body seat 310.

[0044] Referring to Figure 7 , the eccentric assembly 340 is arranged at the other end of the driving shaft 320, the eccentric assembly 340 is connected with the vertical swing assembly 410, and the vertical swing assembly 410 is vertically swung by the eccentric rotation of the eccentric assembly 340. It needs to be further explained that the vertical swing amplitude of the vertical swing assembly 410 is associated with the eccentric distance of the eccentric assembly 340, when the eccentric distance is larger, the vertical swing amplitude of the vertical swing assembly 410 is larger, and vice versa. Therefore, the vertical swing amplitude of the vertical swing assembly 410 can be adjusted by replacing or adjusting the eccentric distance of the eccentric assembly 340, so that the vertical swing assembly 410 reaches the swing height or amplitude along the vertical direction.

[0045] The eccentric assembly 340 is connected with the duckbill type planting assembly 420, and the duckbill type planting assembly 420 is opened or closed by the eccentric rotation of the eccentric assembly 340. In the vertical downward movement process of the duckbill type planting assembly 420, the duckbill type planting assembly 420 is opened by the eccentric assembly 340, when the duckbill type planting assembly 420 moves to the lowest point, the duckbill type planting assembly 420 is in the maximum opening state, and when the duckbill type planting assembly 420 moves vertically upward, the duckbill type planting assembly 420 gradually closes until completely closed.

[0046] In a preferred embodiment, referring to Figure 7The eccentric assembly 340 comprises a cam 341, an eccentric rod 342 and a pullback piece 343. The cam 341 is sleeved on one end of the driving shaft 320 and is driven to rotate by the driving shaft 320. The eccentric rod 342 is rotatably arranged on the outer edge region of the cam 341, and the other end of the eccentric rod 342 is rotatably connected with the vertical oscillating assembly 410. Specifically, the outer edge region of the cam 341 is provided with an eccentric protrusion, and the eccentric rod 342 is rotatably sleeved with the eccentric rod 342. During the rotation of the cam 341, the eccentric rod 342 is driven to move eccentrically, and the vertical oscillating assembly 410 is driven to move by the eccentric rod 342. The pullback piece 343 is rotatably arranged on the moving vehicle body 100, and one end of the pullback piece 343 is slidably connected with the outer end surface of the cam 341.

[0047] In a preferred embodiment, referring to Figure 7 The pullback piece 343 comprises a hinged seat 3431, an extension rod 3432 and a roller 3433. The hinged seat 3431 is arranged on the moving vehicle body 100. One end of the extension rod 3432 is rotatably connected with the hinged seat 3431, and the other end of the extension rod 3432 is rotatably connected with the roller 3433. The roller 3433 is located on the side close to the cam 341, and the roller 3433 and the outer end surface of the cam 341 are in rolling contact with each other. The roller 3433 and the extension rod 3432 are located above the cam 341. Since the cam 341 has a protruding portion, and the roller 3433 and the outer end surface of the cam 341 are in sliding contact with each other, when the cam 341 rotates, the protruding portion of the cam 341 is in contact with the roller 3433, and the roller 3433 rolls on the outer end surface of the protruding portion of the cam 341. Since the roller 3433 is located above the cam 341, the protruding portion of the cam 341 lifts the roller 3433. Since the roller 3433 is located at one end of the extension rod 3432, one end of the extension rod 3432 is lifted upward, and the other end of the extension rod 3432 rotates around the hinged seat 3431. When the roller 3433 moves out of the protruding portion of the cam 341, the roller 3433 is lowered under the action of gravity, and one end of the extension rod 3432 moves downward to return to the initial rolling position.

[0048] It should be further explained that the protruding portion of the cam 341 and the eccentric protrusion of the cam 341 are arranged in a staggered manner. The staggered arrangement position is adjusted according to the rotation position of the eccentric rod 342 and the lifting position of the roller 3433. The seedling planting mode of planting seedlings into a furrow or into soil can be realized.

[0049] Specifically, referring to Figure 7 , Figure 8 and Figure 9 , the planting mode of the pot seedling planted into the furrow is (without the need of the duck-billed planting assembly 420 to break the soil, the duck-billed planting assembly 420 only plants): the connecting line of the eccentric protrusion of the cam 341 to the axis of the cam 341 is X1, the starting position of the protruding part of the cam 341 to the connecting line of the axis of the cam 341 is X2, the ending position of the protruding part of the cam 341 to the connecting line of the axis of the cam 341 is X3, the included angle between X1 and X2 is 90°-110°, and the included angle between X1 and X3 is 160°-180°.

[0050] Specifically, the planting mode of the pot seedling planted into the furrow is that the included angle between X1 and X2 is 100°, and the included angle between X1 and X3 is 170°. When the eccentric rod 342 drives the vertical swing assembly 410 to move upward, that is, the eccentric rod 342 indirectly drives the duck-billed planting assembly 420 to move towards the side close to the pot seedling containing assembly 520, the protruding part of the cam 341 is not in contact with the roller 3433 (in a far state), the back-pulling piece 343 does not pull the duck-billed planting assembly 420 to be in an open state, and when the pot seedling containing assembly 520 drops the pot seedling into the duck-billed planting assembly 420, the pot seedling is stored in the duck-billed planting assembly 420 and does not fall on the ground, preventing the pot seedling from being damaged. When the eccentric rod 342 drives the vertical swing assembly 410 to move downward, that is, the eccentric rod 342 indirectly drives the duck-billed planting assembly 420 to move away from the side close to the pot seedling containing assembly 520, or in other words, the duck-billed planting assembly 420 moves close to the ground, the protruding part of the cam 341 is in contact with the roller 3433 (in a close state), the protruding part of the cam 341 lifts the roller 3433, and then the extension rod 3432 of the back-pulling piece 343 pulls the duck-billed planting assembly 420, so that the duck-billed planting assembly 420 is gradually opened. When the duck-billed planting assembly 420 moves to the lowest point, the protruding part of the cam 341 lifts the roller 3433 to the maximum height, and the duck-billed planting assembly 420 is also opened to the maximum width. The pot seedling in the duck-billed planting assembly 420 falls on the ground or behind the furrow, and since the pot seedling falls close to the ground, it does not cause great damage to the pot seedling, ensuring the integrity of the pot seedling and being conducive to the growth of the pot seedling.

[0051] Specifically, the seedling planting mode of the pot seedling planted into the soil (the duckbill type planting assembly 420 needs to break the soil and plant the seedling) is that the connecting line of the eccentric protrusion of the cam 341 from the axis of the cam 341 is Y1, the starting position of the protruding part of the cam 341 from the connecting line of the axis of the cam 341 is Y2, the ending position of the protruding part of the cam 341 from the connecting line of the axis of the cam 341 is Y3, the included angle between Y1 and Y2 is 160°-180°, and the included angle between Y1 and Y3 is 90°-110°.

[0052] Specifically, the pot seedling planting mode is that the angle between X1 and X2 is 100°, and the angle between X1 and X3 is 170°. When the eccentric rod 342 drives the vertical swing assembly 410 to move upward, that is, the eccentric rod 342 indirectly drives the duckbill planting assembly 420 to move towards the side close to the pot seedling containing assembly 520, the convex part of the cam 341 is not in contact with the roller 3433 (in a state of moving away), the back-pulling piece 343 does not pull the duckbill planting assembly 420 to be in an open state, and when the pot seedling containing assembly 520 drops the pot seedling into the duckbill planting assembly 420, the pot seedling is stored in the duckbill planting assembly 420 and does not fall on the ground, preventing the pot seedling from being damaged. When the eccentric rod 342 drives the vertical swing assembly 410 to move downward, that is, the eccentric rod 342 indirectly drives the duckbill planting assembly 420 to move away from the side of the pot seedling containing assembly 520, or in other words, the duckbill planting assembly 420 moves close to the soil and is inserted into the soil as it moves, to a preset depth, such as 8-15 cm, the duckbill planting assembly 420 forms a planting hole, at this time, the duckbill planting assembly 420 moves to the lowest point and is still in a closed state. When the duckbill planting assembly 420 rises, the convex part of the cam 341 is in contact with the roller 3433 (in a state of moving close), the convex part of the cam 341 lifts the roller 3433, and then the extension rod 3432 of the back-pulling piece 343 pulls the duckbill planting assembly 420, so that the duckbill planting assembly 420 is gradually opened. As the duckbill planting assembly 420 gradually rises, the convex part of the cam 341 lifts the roller 3433 to the maximum height, and the duckbill planting assembly 420 is also opened to the maximum width, and the pot seedling in the duckbill planting assembly 420 falls into the planting hole formed by the duckbill planting assembly 420. After the roller 3433 passes the highest point of the convex part of the cam 341, the roller 3433 descends and drives the duckbill planting assembly 420 to be closed. Since the pot seedling falls close to the planting hole, it does not cause great damage to the pot seedling, ensuring the integrity of the pot seedling and being conducive to the growth of the pot seedling.

[0053] The eccentric rod 342 drives the vertical swing assembly 410 to swing upward, so that the duckbill planting assembly 420 performs the seedling collection process. The eccentric rod 342 drives the vertical swing assembly 410 to swing downward, the convex part of the cam 341 lifts the roller 3433, so that the duckbill planting assembly 420 is in an open state, and then the duckbill planting assembly 420 performs the seedling planting process. This process runs continuously, the pot seedlings are arranged in order after planting, the spacing is moderate, and it is conducive to the growth and development of the pot seedlings.
