Description

Self-propelled garlic planter

The present invention relates to a garlic planter, and is not towed by a manager, a cultivator, or a tractor, and while traveling in a self-propelled manner by a tracked wheel, it is possible to run semi-autonomously along the foot without manual steering through the foot recognition by the foot sensor. It is possible to adjust the seeding depth of side garlic by height control and the daytime distance by the transmission, and it is possible to automatically replenish in case of failure to minimize the rate of run-out. It relates to a self-propelled garlic planter with an improved structure that prevents interference even if it is formed at the same time.

In general, garlic planters are divided into two types: a sowing type, in which garlic is dropped one by one in the bones in a natural dropping method, and sown, and a branching type in which garlic is planted and covered one by one. Most of the sowing is towed by a manager, a cultivator, or a tractor.

On the other hand, in the case of sowing by attaching to a manager or a cultivator, there was a problem that it was inconvenient for the operator to operate the manager or cultivator, and a situation in which the seeding condition was disturbed by stepping on the sown bedside occurred. Therefore, in the case of sowing, if the tractor's tracks are wide and there is a lot of moisture in the soil, the wheel marks of the tractor are hardened, resulting in poor stopping conditions, and sowing at the starting point and the return point is impossible. There was a problem that a trained driver was needed.

In addition, in the case of the above-described sowing type or point wave type seeding machine, the rate at which the chives in the hopper are not sown in the process of picking and feeding them to the seeding unit one by one at the seeding unit, that is, the rate of absent In addition to decreasing the yield due to the increase in wave rate), there was also a problem in that the missing part had to be repaired manually after machine sowing.

As a prior art for solving such a problem, a seed planter with improved breaking rate of Patent Document 1 is disclosed, and Patent Document 1 consists of a method of performing a seed pouring operation in the form of slant seedling and cushion roll, It is constructed so that it is possible to visually check that garlic seeds fall into the cup, which means that it can quickly respond to the breakage, that is, manually replenish the broken part, thus minimizing breakage and overlapping seeding. In the case of supplementary work, there was a disadvantage that the work was not easy because two people had to make one group.

Patent Document 2 discloses a branched garlic planter developed by the present applicant, which is a method used by being towed by a tractor, and there is a problem that it is impossible to supplement when a runout occurs.

Patent Document 3 also discloses a garlic seeding machine developed by the present applicant, which is a tray where garlic is not loaded because the pear seeding unit for loading and transporting garlic is vertically upright so that the user can visually check whether the garlic is mounted on the tray. It consists of a structure that makes it easy to put garlic directly in, but there is a disadvantage that such supplementary work must be done one by one while the worker is on board.

Patent Document 4 discloses a sowing-type garlic seeding machine of the present applicant, which is densely seeded so that two rows form a pair, and the interval between each group can be arbitrarily adjusted so that it is suitable for the growing environment of garlic. Although it is designed to ensure ventilation and light-emitting properties, Patent Document 4 has a drawback that the absent rate is low because there is no special countermeasure against the absence of garlic seeds in Patent Document 4, and the two rows of one pair are too close to form a valley. In the process, there is also a problem in that a phenomenon in which the goal of the goal is not performed properly occurs because the soil raised while forming one valley is pushed into the inside of the other valley.

The rotation feeder further includes a miss detection sensor for detecting that a runout occurs, and a supplement means for replenishing garlic when a runout occurs, and the supplement means is disposed symmetrically with the disk of the rotation feeder to pick up the garlic from the hopper. It provides a self-propelled garlic seeding machine that is configured to drop clove garlic downward while rotating intermittently when a runaway occurs while waiting.

The replenishment means is basically of the same structure as the rotation feeder, but the gripper radially disposed on one side of the rotating disk is configured to pick up the side garlic of the hopper one by one and supply it to the bottom, so that the gripper radially disposed in the rotation feeder The gripper opens and drops the pickled garlic into the chute only when it is rotated without picking up the side garlic and the side garlic is not dropped downward.

In a preferred embodiment, the rotary feeder, the chute, and the goltargi blade are arranged in a plurality of rows, and the chute and the goltargi blade are arranged in a staggered position before and after adjacent ones so that interference does not occur during cultivation and sowing. .

1 to 9 shows a self-propelled garlic planter 1 according to an embodiment of the present invention, which is provided with a caterpillar wheel 110 on the left and right sides and a vehicle body 100 provided with a driver's seat 120 on the upper front side. The seeding unit 200 is installed in the rear inner side of the

Pile detection sensors S1, S2, S3, S4 are provided on the front left and right sides of the vehicle body 100 to control steering in a semi-autonomous driving method along the ridge by non-contact sensing,

The seeding unit 200 includes a hopper 210 containing parsley; A rotation feeder 220 which is positioned under the hopper 210 and is radially disposed on one side of the rotating disk 222 to pick up the garlic of the hopper 210 one by one and supply it to the lower side; A chute 230 for dropping the side garlic supplied from the rotary feeder 220 downward; Goltagi blade 240 to form a bone on the head of the garlic to be sown; Consisting of including a cover blade 250 that covers the soil after the garlic is sown in the valley formed on the duke,

As shown in Figs. 7 to 9, the rotation feeder 220 includes a miss detection sensor 270 for detecting that a runout occurs in the gripper 224, and a supplement means 280 for replenishing the garlic when runout occurs. It further includes, and the replenishment means 280 is disposed symmetrically with the disk 222 of the rotation feeder 220 to pick up garlic from the hopper and wait for it to intermittently rotate while dropping the scallion garlic into the chute 230 Is configured to

In this embodiment, the heading sensor (S1, S2, S3, S4) can be moved so that the left and right spacing can be adjusted according to the spacing between the head of the field and the furrow to be sown on the horizontally disposed sensor mounting table 102 And the dug detection sensors (S1, S2, S3, S4) are installed to detect the boundary between the furrows on both sides of the dug in a diagonal direction as shown in FIG. The heading sensor is installed on the left and right sides of the vehicle body 100 so that the position can be adjusted, and each pair of heading sensor (S1, S2, S3, S4) is It is composed of specifications that can adjust the irradiation direction according to the width, and the patter detection sensor used in this embodiment is a kind of ultrasonic sensor, and the trademark name'SONICTRAKK' of PROTRAKKER, but the present invention is not limited thereto, and the lidar sensor Of course, it can also be applied as a detection sensor.

The controller (not shown) controls the hydraulic steering device (not shown) according to the signal detected by the pile detection sensors (S1, S2, S3, S4), so that the garlic planter accurately follows the direction of the straight or curved pile. Because it helps to drive, the driver sitting in the driver's seat does not care only about the steering, but monitors the seeding status, adjusts the seeding depth and seeding interval, and observes the surrounding situation with the naked eye, enabling immediate coping. Therefore, the hassle of tedious manual steering control and Difficulties can be avoided, and even those who do not have precise steering skills can make stable steering and seeding possible.

The control mechanism for semi-autonomous driving of the seed drill by the above-described duke detection sensors (S1, S2, S3, S4) is a known technology, so a detailed description thereof will be omitted.

Although the steering wheel is omitted in the accompanying drawings, a steering wheel in the form of a steering wheel can be installed in the front of the driver's seat, and a steering device of various structures can be applied, and a hydraulic steering device of a known caterpillar agricultural machine can be applied. It is desirable.

In addition, a power device for driving the wheel 110 other than the steering wheel is not shown on the drawing. It goes without saying that such a power device may be an electric or hydraulic motor using a known internal combustion engine or a rechargeable battery. .

In addition, the driver's seat 120 side is further provided with a display panel and a control unit for displaying and storing a lever or switch for operating the transmission, and the seeding state of the seeding unit, that is, the seeding depth, the seeding interval, and the absence state. Since the configuration of the and operation unit is also a general matter, detailed illustration and description thereof will be omitted.

The miss detection sensor 270 detects that the gripper 224 of the rotation feeder 220 rotates without picking up the garlic, and controls the driving of the supplemental means 280 by the detected signal. The replenishment means 280 has the same structure as the rotation feeder, that is, a gripper 284 is disposed radially on one side of the rotating disk 282 to pick up the garlic of the hopper 210 one by one and drop it downward. And, only when the side garlic is not dropped into the chute 230 because the side garlic is rotated without picking up the side garlic by the gripper 224 disposed radially in the rotation feeder 220, the side where the gripper 284 was opened and picked up After the garlic is dropped into the chute 230, it is rotated by a certain angle, that is, the installation angle of the gripper, and waits for the next supplemental signal, so when a run out of the rotating feeder 220 occurs, the garlic is automatically supplied to minimize the runaway rate. There will be.

The miss detection sensor 270 includes a sensor 270a for detecting whether or not a gripper 224 radially installed on the disk 222 of the rotation feeder 220 is picking up garlic, and the supplemental means 280 The gripper 284 arranged radially on the disk 282 of the is composed of a sensor 270b to detect whether it is picking up the side garlic for supplementation, and it is missed at one side of the miss detection sensor 270a (the state that the side garlic is not picked) When is sensed, a driving signal is sent to the replenishing means 280 to drop the side garlic held by the gripper 284 of the replenishing means 280 onto the chute 230, thereby minimizing the runaway rate.

On the other hand, another absence detection sensor (270b) for detecting whether the gripper 284 of the replenishing means 280 is picking garlic is stopped at the dropping standby position when the gripper 284 is picking garlic. And, when the gripper 284 does not pick up the garlic, the disk 282 is rotated by 1 pitch, so that the supplementary garlic is always waiting at the dropping standby position.

In the drawing, reference numeral 286 denotes a servo motor for intermittently driving the disk 282 of the supplementary means 280.

The miss detection sensor 270 may use an ultrasonic sensor, a photosensor, or a laser sensor, and detects whether the gripper 224 of the rotary feeder 220 is picking up garlic, and sends a signal to the controller (not shown). Then, the control unit transmits a drive signal to the supplemental means 280 when it is determined that it is absent, so that the disc 282 is intermittently rotated and the gripper 284 is opened.

On the other hand, in the present embodiment, the driving of the rotation supply 220 is driven by the rotational force transmitted through the

power transmission chains

262, 264, 266, 268 from the driving wheel 260 that rolls in contact with the caterpillar wheel 110, and At (260), a transmission 263 is installed between the rotation feeders 220 for transmission, and the rotational speed of the rotation feeder 220 is changed by operating the shift lever to adjust the front and rear seeding intervals, i.e., the weekly intervals. However, since the transmission 263 is a matter that is self-evident by a person of ordinary skill in the technical field to which the present invention belongs, a detailed illustration and description thereof will be omitted, and the seeding unit 200 is a height sensor As shown in Fig. 6, when the seeding depth is not automatically adjusted, as well as the automatic adjustment of the seeding depth by allowing the lifting operation to be performed by the hydraulic cylinder 206 controlled by the 208, the seeding unit 200 is attached to the vehicle body ( 100) It is designed to be able to run while being completely raised to the top or to perform inspection of the seeding unit 200.

In addition, in this embodiment, the rotation feeder 220, the chute 230, and the goltagi blade 240 are arranged in a plurality of left and right rows as shown in the bottom perspective view of FIG. 3 and the side cross-sectional view of FIG. 4, The chute 230 and the goal tagging blade 240 are arranged in an alternating position back and forth between adjacent ones to the left and right so that interference does not occur when forming a bone, but one of the chutes 232 is located in the front. It is installed obliquely toward the rear of the blade 240, and the other chute 234 is installed toward the rear of the goalagi blade 240 located at the rear.

That is, since a plurality of bones adjacent to the left and right are arranged close to each other, when the left and right bones are formed at the same position in the same position left and right, the adjacent bones are used. As the soil is pushed and the valley collapses, the depth of the valley decreases, making it impossible to form an appropriate seeding depth, and even if the soil is covered by the cover blade 250 after sowing, even if the soil is covered by the cover blade 250, the sufficient thickness is not covered, resulting in cold damage. There was a fear that, in the drawing of this embodiment, it is composed of a six-row type that can simultaneously form a goal in six rows on the left and right on the head bank, but since the goltagi blades 240 adjacent to the left and right are arranged to be staggered from each other back and forth, sufficient distance Since the bones are formed in a state of being separated from each other, the interference phenomenon that the bones collapse can be effectively resolved.

On the other hand, in this embodiment, since the goltagi blades 240 adjacent to the left and right are arranged to be staggered back and forth, from the bottom of the rotary feeder 220 to drop the skewer garlic on the bone formed by the goltagi blade 240, Afterwards, inclined

chutes

232 and 234 are installed.

The seeding unit 200 is configured to be able to move up and down from the rear inner side of the vehicle body 100, which prevents damage to the seeding unit 200 when moving before and after the seeding operation as shown in FIG. In order to maintain the lifted state, it is possible to adjust the seeding depth of garlic by varying the height at the time of seeding. The seeding unit frame 202 is suspended from the lift arm 204, and the hydraulic cylinder 206 is stretched and contracted. As a result, as the lift arm 204 is lifted or lowered, the whole seeding unit 200 is raised and lowered.

On the other hand, in the present invention, the seeding portion is configured to be able to adjust the seeding depth by a height sensing sensor 208 contacting the top of the pile as shown in FIGS. 3 and 6, and the vehicle body 100 and the seeding portion 200 ), a height adjustment hydraulic cylinder 206 is provided, and the height adjustment hydraulic cylinder 206 interlocks according to the height of the pile detected by the height sensor 208 to automatically adjust the seeding depth of garlic to the height of the pile. It can be adjusted to keep the seeding depth of garlic constant at, for example, 3~5cm, so that uniform growth of garlic is possible.

The height adjustment hydraulic cylinder 206 and the height detection sensor 208 are arranged on each of the left and right sides, respectively, so that the left and right heights are separately sensed and the left and right hydraulic cylinders are individually controlled, so that the seeding is carried out even on the left and right slopes. The depth can be kept constant.

The height detection sensor 208 has a sensor 208a installed on the inside of the seeding unit frame 202, and a probe 208b in contact with the upper surface of the ridge is rotatably attached to the sensor 208a so that it contacts on the ridge. The sensor 208a senses the rotational state of the probe 208b moving in one state, and measures the height of the ridge, and between the left and right vehicle bodies 100 and the seeding part 200 according to the measured height of the ridge. The height of the seeding unit 200 is feedback-controlled in accordance with the height change of the ridge by expanding and contracting the hydraulic cylinder 206 for height adjustment installed in the.

As described above, the garlic seeding machine according to the present embodiment sowings garlic while traveling independently in a semi-autonomous driving method, so that the operator can operate in a comfortable state, and does not require a separate cultivator, a manager, or a tractor. Therefore, it has the advantage that it is possible to sow mechanically even in a small field, and even if a run-out occurs in the gripper of the rotary feeder during sowing, the run-out detection sensor detects it and operates the replenishment means to replenish the garlic, thus minimizing the run-out rate. It is possible to increase the yield, and sowing can be carried out at a certain depth depending on the height of the ridge even in inclined fields or other fields where the height of the ridge is not constant, and since the goltargi blades and chutes arranged in multiple rows are arranged to be shifted back and forth. As there is no interference phenomenon when riding, there are advantages such as being able to sow and cover the garlic in a stable depth.
