Description

Technical Field

[0001] The present invention relates to the technical field related to seed collection, and in particular to an automatic forest seed collection device and a seed collection method thereof. Background Art

[0002] Wood forest seed collection refers to the collection of plant seeds in wood forests.

[0003] Most existing seed collection equipment uses vibration collection, which means applying vibration to the tree to drive the seeds off the tree through the vibration; However, the problem with this type of seed collection method is that the vibration equipment and the collection equipment are usually operated separately, which makes the seed collection preparation time longer, thereby affecting the seed collection efficiency; Secondly, during vibration collection, not only seeds fall off, but also dust on trees, dry leaves, branches, etc., which will be mixed into the seeds when collected by the collection equipment, resulting in the need to separate the seeds in subsequent processes. Summary of the Invention

[0014] The present invention also provides a method for automatically collecting forest seed, which uses the automatic forest seed collecting device and includes the following steps: Step 1: Use the hydraulic mechanical arm to drive the base to move to the specified position, and make the two clamping arms and the two buckle seats on both sides of the tree trunk, then drive the two buckle seats and the two clamping arms to move relative to each other, and clamp the tree trunk through the two clamping arms; Step 2: When the vibrating element is working, it generates high-frequency vibrations to drive the seeds to fall through the inoculation pad for collection. The seeds that fall into the inoculation pad will fall into the collection box, and then the seeds will be transported by the feeding component. During the transportation process, the powder, dust and shriveled fruits mixed in the seeds will be removed; Step 3: Finally, the seeds are transported to the impurity removal component to remove larger impurities in the seeds and finally obtain clean seeds.

[0015] The present invention has the following beneficial effects: 1. The automatic tree seed collecting device integrates a vibration device and a collection device, so that the collection device can be placed under the tree while the vibration device is being prepared; The above-mentioned effect of the present invention is to drive the two snap-fitting seats and the two clamping arms to move synchronously relative to each other. If the two snap-fitting seats and the two clamping arms move at the same stroke, both clamping arms will clamp the tree trunk. The vibration is generated by the vibrating element on the clamping arm, and the clamping of the two snap-fitting seats will affect the generation of vibration. In the present invention, after the clamping arm clamps the tree, the buckle seat does not contact the tree trunk, which will cause a gap between the tree trunk and the buckle seat, causing the seeds to fall. The sliding shaft provided in the present invention can solve this problem.

[0016] Second, the automatic forest seed collection device collects seeds through the inoculation pad and enters the collection box through the discharge port, that is, the conveying component, and then transports the seeds to the impurity removal component through the conveying component; The conveying component separates the smaller impurities mixed in the seeds during the conveying process; Secondly, the seeds collected by the inoculation pad enter the collection box through the discharge port. After the seeds fall, they are immediately stored in the collection box and transported to the centralized separation box through the bellows. Then, after the seeds finish falling, the two snap-fit ​​seats can be immediately driven to move in opposite directions, and preparations for the next tree can be immediately carried out.

[0017] 3. The automatic forest seed collecting device can separate the heavier impurities that cannot be removed by the seeds conveying component through the separation component, and finally obtain relatively clean seeds.

[0018] 4. The automatic tree seed-collecting device of the present invention has a relatively high degree of automation. It only needs to drive the base to move to the specified position through the hydraulic mechanical arm, so that the tree trunk is between the two snap-fit ​​seats and the two clamping arms, to complete automatic seed collection, automatic collection, and automatic debris removal.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0024] The following is based on Figures 1-18 The automatic tree seed collecting device provided by an embodiment of the present invention is described.

[0025] like Figures 1-18 As shown, an embodiment of the present invention provides a technical solution: an automatic tree seed collection device, comprising a base 1, one end of which is fixed to a hydraulic mechanical arm; Two snap-fitting seats 2 are arranged opposite to each other. The two snap-fitting seats 2 are slidably mounted on the other side of the base 1. Two clamping arms 3 are also slidably mounted on the bottom of the base 1. The two clamping arms 3 are fixed to the two snap-fitting seats 2; The two snap-fit ​​seats 2 are connected to the driving member installed on the base 1, and the two clamping arms 3 are both equipped with a vibrating member; A central groove for accommodating tree trunks is formed by two snap-fitting seats 2. The two snap-fitting seats 2 are hinged with multiple support rods 202 at equal distances around the central groove. Inoculation pads 201 are fixed on the support rods 202. The two snap-fitting seats 2 are provided with multiple discharge ports 207 at equal distances around the circumference. The discharge ports 207 are connected to a feeding assembly installed at the bottom of the base 1, and the feeding assembly is connected to a debris removal assembly installed at the bottom of the base 1.

[0026] In the embodiment of the present invention, when harvesting seeds, the hydraulic mechanical arm is driven to move to a specified position, that is, the two snap-fit ​​seats 2 are located on both sides of the tree trunk. Then, the driving member drives the two snap-fit ​​seats 2 to move relative to each other, and at the same time, the two clamping arms 3 follow the movement of the snap-fit ​​seats 2. When the two buckling seats 2 move relative to each other, the inoculation pad 201 on the buckling seat 2 and the inoculation pad 201 are driven to move synchronously, and a concentration bucket is formed by the movement of the two buckling seats 2 and the inoculation pad 201 for collecting seeds; The support rod 202 is reversible and can be turned over and stored after the seed collection work is completed; When the two clamping arms 3 are relative to each other at the end of the stroke, they clamp the tree trunk, and the vibrating member generates vibration, causing the seeds to fall. The fallen seeds are collected by a collecting bucket, and then fall to the feeding assembly through the discharge port 207. The seeds are transported to the impurity removal assembly through the feeding assembly, and the impurities mixed in the seeds are removed by the impurity removal assembly to obtain cleaner seeds.

[0027] The two buckle seats 2 are provided with inclined sliding holes 206 at equal distances on the circumference. A sliding shaft 204 is slidably installed in the sliding hole 206. A spring 205 is fixed to the end of the sliding shaft 204. The other end of the spring 205 is fixed to the bottom of the sliding hole 206. The gap between two adjacent sliding shafts 204 is smaller than the diameter of the seed.

[0028] In the embodiment of the present invention, when the two snap-fit ​​seats 2 move relative to each other, the two clamping arms 3 are simultaneously driven to move relative to each other. The clamping arms 3 need to clamp the tree trunk. This method will cause the snap-fit ​​seats 2 to also clamp the tree trunk, which will affect the transmission of vibration. The solution of this embodiment is that the two snap-fit ​​seats 2 do not contact the tree trunk when they move to abutment, and the sliding shaft 204 elastically abuts the tree trunk, thereby avoiding affecting the transmission of vibration. Moreover, since the sliding shaft 204 is in an inclined state, it can better drive the seeds toward the discharge port 207. When the trunk vibrates, the sliding shaft 204 will be driven to move axially. By compressing the spring 205, the spring 205 stores elastic potential energy and drives the sliding shaft 204 to reset through the elastic potential energy. Since the snap-fit ​​seat 2 is not in contact with the trunk, there must be a gap between the trunk and the snap-fit ​​seat 2, and the sliding shaft 204 can fill the gap.

[0029] The driving member includes a bidirectional screw rod 503 rotatably mounted on the base 1 , and two threaded sleeves 502 threadedly matched with the bidirectional screw rod 503 are sleeved on the bidirectional screw rod 503 , and the two threaded sleeves 502 are fixed to the two buckle seats 2 respectively; A motor 5 is fixed on the base 1 , and an output shaft of the motor 5 is connected to a bidirectional screw rod 503 via a third transmission chain 501 .

[0030] In the embodiment of the present invention, when the motor 5 is working, its output shaft drives the bidirectional screw 503 to rotate through the third transmission chain 501. When the bidirectional screw 503 rotates, the two threaded sleeves 502 and the two buckle seats 2 move relative to each other or in opposite directions by engaging with the threads of the two threaded sleeves 502. Among them, since seed collection is usually done outdoors and outdoor electricity is usually obtained from batteries, in order to keep the capacity of the battery unchanged, the motor 5 can work for a longer time. Since this embodiment adopts threaded transmission, a smaller power motor 5 can achieve energy saving. The torque required to drive the bidirectional screw 503 to rotate in the present invention is relatively small, and thus the motor 5 can adopt a smaller power motor.

[0031] The inoculation pad 201 is a sandwich arrangement.

[0032] In the embodiment of the present invention, air is inflated into the interlayer of the inoculation pad 201 by a pumping device, so that the inoculation pad 201 bulges; Among them, since the outer side of the inoculation pad 201 is fixed to the support rod 202, when the inoculation pad 201 is inflated, the inner side of the inoculation pad 201 bulges. This effect can play a shock-absorbing role when the seeds fall. Some seeds will fall off when they are hit after drying, which will affect the subsequent processing of the seeds. This embodiment can effectively solve this problem.

[0033] The feeding assembly includes a bracket 6 fixed to the bottom of the base 1, a centralized separation box 601 is fixed to the bottom of the bracket 6, two bellows 602 connected to the centralized separation box 601 are fixed, and two collection boxes 203 are fixed to the bottom of the two snap-fit ​​seats 2 respectively. The bottoms of the two collection boxes 203 are both inclined, and the ends of the bellows 602 away from the centralized separation box 601 are connected to the lower positions of the two collection boxes 203; The bottom of the centralized separation box 601 is tilted, and the high side is fixed and connected with the bellows 602; The end of the centralized separation box 601 away from the bellows 602 is open, and the open end of the centralized separation box 601 is connected to the impurity removal component; Two fans 603 are installed at the bottom of the centralized separation box 601 , and blades 604 are installed inside the fans 603 . A ventilation hole 605 is opened at the bottom of the centralized separation box 601 , and a debris discharge port 606 is opened at the top of the centralized separation box 601 .

[0034] In the embodiment of the present invention, after the seeds enter the collection box 203, since the bottom of the collection box 203 is tilted, the seeds will move toward the lower position of the bottom of the collection box 203, and then the seeds in the collection box 203 will enter the bellows 602 and be transported to the centralized separation box 601 through the bellows 602; After the seeds enter the centralized separation box 601, since the bottom of the centralized separation box 601 is also tilted, the seeds move toward the lower position, so that the seeds move toward one end of the open portion of the centralized separation box 601, and finally move to the impurity removal component; When the fan 603 is working, it drives the blades 604 to rotate. When the blades 604 rotate, they generate wind force toward the impurity discharge port 606, and then blow out the powder impurities and shriveled seeds mixed in the seeds through the impurity discharge port 606 when the seeds pass through. The function of the ventilation holes 605 is that wind can be blown out through the ventilation holes 605 without seeds entering the fan 603; It should be noted that when picking seeds, the next seed is usually picked immediately after the first seed is picked to ensure the efficiency of picking. During the picking, the seeds will be collected into the collection box 203 in a short time. After the picking is completed, the two snap-fit ​​seats 2 and the collection box 203 need to be driven to move in the opposite direction to release the picking state. When the two snap-fit ​​seats 2 and the collection box 203 move in the opposite direction, the bellows 602 is pulled up and bent by the collection box 203, and then the collection box 203 is transported to the centralized separation box 601 through the bellows 602 without interruption. Of course, a limiting piece for controlling the movement of seeds is provided at one end of the bellows 602 to control the amount of seeds during movement, so as to avoid accumulation of seeds in the concentrated separation box 601, which would result in inefficient blowing out of powder impurities.

[0035] The impurity removal assembly includes two baffles 4 fixed to the bottom of the base 1. Four No. 1 conveying rollers 403 are rotatably mounted at the four corners of the two baffles 4. The four No. 1 conveying rollers 403 are connected by conveying members 402. The conveying member 402 is provided with feeding troughs 3014 at equal intervals. The feeding troughs 3014 cooperate with the centralized separation box 601. The bottoms of the multiple feeding troughs 3014 are all provided with an inclined surface 3015. The conveying member 402 is provided with a separation member, which is connected to one of the No. 1 conveying rollers 403. The conveying member 402 is provided with a limit box 401 that is slidably engaged with the bellows 602. The limit box 401 has notches on both sides. The notch on the side of the limit box 401 facing the bellows 602 is at the bottom, and the notch on the side of the limit box 401 away from the bellows 602 is at the top. The notch at the bottom of the limiting box 401 cooperates with the centralized separation box 601 , and the notch at the top of the limiting box 401 cooperates with the separation piece.

[0036] In the embodiment of the present invention, a high-torque motor is fixed to the bottom of the base 1. The output shaft of the motor is coaxially fixed to one of the No. 1 conveyor rollers 403. When the motor is working, the output shaft drives one of the No. 1 conveyor rollers 403 to rotate, so that when one of the No. 1 conveyor rollers 403 rotates, the conveying member 402 is conveyed, and the other four No. 1 conveyor rollers 403 are driven to rotate at the same time. like Figure 16As shown, when the conveying member 402 is conveying, the feeding trough 3014 on the conveying member 402 will overlap with the opening of the centralized separation box 601 in sequence. When overlapping, the seeds in the centralized separation box 601 will enter the feeding trough 3014. The seeds in the feeding trough 3014 will rise vertically along with the conveying of the conveying member 402, and will be discharged into the separation member when they rise to the designated position. Among them, the notch at the bottom of the limit box 401 is used to dock with the centralized separation box 601, and at the same time, it blocks the seeds in the centralized separation box 601 from entering the feeding trough 3014. The notch at the top of the limit box 401 is used to dock with the separation piece and block the direction of feeding. The technical effect achieved is quantitative and high-frequency delivery, for example, the amount delivered each time is about one kilogram, and the delivery frequency is relatively large, so that the impurities in the seeds can be quickly separated through the separation mechanism, avoiding the problem of accumulation caused by uninterrupted and rapid delivery, and the problem of ineffective separation.

[0037] Secondly, the structure of the quantitative high-frequency feeding achieved by the present invention is very simple, relying only on the transportation of the conveying member 402. Compared with the existing quantitative feeding mechanism, the cost is very low and the structure is simpler. Most of the existing quantitative feeding equipment is made of metal materials, while the main component of the present invention is the conveying member 402, which is made of high-strength flexible material and is more durable.

[0038] The separation member includes a storage box 3011 fixed between the two baffles 4 and located in the conveying member 402. A second conveying roller 408 is rotatably mounted on the inner side and inner side of the storage box 3011. The two second conveying rollers 408 are connected by a conveyor belt 3012, and the conveyor belt 3012 is in an inclined state. A guide piece 3013 is fixed on the side of the storage box 3011 facing the bellows 602 and matches the top notch of the limit box 401. The guide piece 3013 is tilted. A plurality of hooks 3018 are fixed at equal intervals along the conveying path on the conveyor belt 3012, and a plurality of groups of passing slots 3017 are opened at equal intervals along the conveying path on the conveyor belt 3012; A protective plate 3016 fixed to the storage box 3011 is provided inside the conveyor belt 3012; A discharge member 3010 is fixed to the storage box 3011 on the side facing the bellows 602 , a conveyor belt 3012 is located inside the discharge member 3010 , and a blanking comb that cooperates with the hook 3018 is fixed inside the discharge member 3010 ; The second conveying roller 408 is connected to one of the first conveying rollers 403 via a transmission member.

[0039] In the embodiment of the present invention, the transmission member includes a first gear 405 and a second gear 406 rotatably mounted on the baffle 4 and meshing with each other. The first gear 405 is connected to the first conveyor roller 403 via a first transmission chain 404, and the second gear 406 is connected to the second conveyor roller 408 via a second transmission chain 407. When the No. 1 conveyor roller 403 rotates, the No. 1 gear 405 is driven to rotate through the No. 1 transmission chain 404, and the No. 1 gear 405 and the No. 2 gear 406 are engaged with each other to make the No. 1 gear 405 and the No. 2 gear 406 rotate relative to each other. When the No. 2 gear 406 rotates, the No. 2 conveyor roller 408 is driven to rotate through the No. 2 transmission chain 407, and the conveyor belt 3012 is driven to convey when the No. 2 conveyor roller 408 rotates; since the No. 1 gear 405 and the No. 2 gear 406 rotate in opposite directions, the conveying directions of the conveying member 402 and the conveyor belt 3012 are opposite, and the conveying of the conveyor belt 3012 is from a low position to a high position.

[0040] The seeds in the feeding chute 3014 are blocked and limited by the limit box 401, and then driven by the inclined surface 3015 to be put into the introduction member 3013. Since the introduction member 3013 is inclined, the seeds are poured toward the conveyor belt 3012. The seeds poured onto the conveyor belt 3012 fall directly to the bottom of the storage box 3011 through the groove 3017, while some relatively large impurities are transported toward the discharge member 3010 through the claw 3018, and finally fall into the discharge member 3010 and are discharged to the outside of the storage box 3011 through the discharge member 3010. The blanking comb is used to remove impurities stuck on the hook claws 3018. Its shape and function are basically the same as those of a comb. The blanking comb is not shown in the figure.

[0041] It should be noted that the size of the slot 3017 can be changed according to the volume of the collected seeds. Since the seeds entering the storage box 3011 have already been winnowed and impurities of light weight have been removed, the remaining impurities are heavier impurities such as leaves or branches. Therefore, the diameter of the slot 3017 can be set relatively large, and there is no need for the holes to be as dense as a sieve. Among them, the function of the protective plate 3016 is to block and limit the seeds to prevent the seeds from falling onto the No. 2 conveyor roller 408 and being crushed by the conveyor belt 3012.

[0042] The bottom of the storage box 3011 is tilted, and a seed outlet is provided at the lower position of the storage box 3011 and on the baffle 4. A blocking plate 409 is installed at the seed outlet for sealing the seed outlet.

[0043] In the embodiment of the invention, the seed outlet is opened or closed by driving the blocking plate 409 to slide upright.

[0044] The vibrating member includes a mounting groove 301 formed on the two clamping arms 3, and an eccentric shaft 302 is rotatably mounted in the mounting groove 301; The eccentric shaft 302 includes a shaft body and an eccentric block fixed on the shaft body; A transmission cylinder 305 is rotatably mounted at the bottom of the baffle 4. Two transmission rods 307 are slidably mounted in the transmission cylinder 305. A plurality of transmission bars 309 are fixed to the transmission rod 307. The transmission bars 309 slidably cooperate with transmission grooves 308 provided in the transmission cylinder 305. The transmission rod 307 is connected to the eccentric shaft 302 via a bevel gear set 303. A follower plate 304 rotatably connected to the eccentric shaft 302 is also rotatably mounted on the transmission rod 307. The transmission cylinder 305 is connected to one of the first conveying rollers 403 via a synchronous belt 306 .

[0045] In the embodiment of the present invention, when the No. 1 conveyor roller 403 rotates, the transmission drum 305 is driven to rotate via the synchronous belt 306. In this process, a large pulley is provided on the No. 1 conveyor roller 403 and a small pulley is provided on the transmission drum 305 to increase the speed. When the transmission cylinder 305 rotates, the two transmission rods 307 are driven to rotate synchronously through the cooperation of the transmission bar 309 and the transmission groove 308. When the transmission rod 307 rotates, the eccentric shaft 302 is driven to rotate through the bevel gear set 303. When the eccentric shaft 302 rotates, the presence of the eccentric block generates vibration. The vibration is transmitted to the clamping arm 3 and then to the tree trunk through the clamping arm 3, so that the high-frequency vibration of the tree trunk drives the seeds to fall. Among them, since the two clamping arms 3 will move in relative or opposite directions during construction or when the construction is completed, the movement of the two clamping arms 3 will drive the two eccentric shafts 302 to move synchronously. When the eccentric shaft 302 moves, the follower plate 304 drives the transmission rod 307 to move axially along the transmission cylinder 305. Since the transmission between the transmission cylinder 305 and the transmission rod 307 is transmitted through the transmission rod 307 and the transmission groove 308, the transmission relationship between the transmission rod 307 and the transmission cylinder 305 is not affected when the transmission rod 307 moves axially along the transmission cylinder 305.

[0046] It should be noted that the bevel gear set 303 includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the transmission rod 307 and the eccentric shaft 302 respectively.

[0047] The present invention also provides a method for automatically collecting forest seed, which uses the automatic forest seed collecting device and includes the following steps: Step 1: Use the hydraulic mechanical arm to drive the base 1 to move to the specified position, and make the two clamping arms 3 and the two snap-fit ​​seats 2 on both sides of the tree trunk, then drive the two snap-fit ​​seats 2 and the two clamping arms 3 to move relative to each other, and clamp the tree trunk through the two clamping arms 3; Step 2: When the vibrating element is working, it generates high-frequency vibrations to drive the seeds to fall through the inoculation pad 201 for collection. The seeds that fall into the inoculation pad 201 will fall into the collection box 203, and then the seeds are transported by the feeding component. During the transportation process, the powder, dust and shriveled fruits mixed in the seeds are removed; Step 3: Finally, the seeds are transported to the impurity removal component to remove larger impurities in the seeds and finally obtain clean seeds.
