DETAILED DESCRIPTION

[0069] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0070] In the description of the application, it should be understood that the terms “opening”, “upper”, “lower”, “thickness”, “top”, “middle”, “length”, “inner”, “periphery” and the like indicate the orientation or positional relationship, which are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application. ​

[0071] The application is described below according to Figures 1-18 The application provides a device for automatically collecting seeds of trees.

[0072] As Figures 1-18 shown in the drawings, the application provides a technical solution: a device for automatically collecting seeds of trees, comprising a base 1, one end of which is fixed with a hydraulic mechanical arm;

[0073] Two buckling seats 2 are oppositely arranged, and both are slidingly installed on the other side of the base 1. Two clamping arms 3 are also slidingly installed on the bottom of the base 1, and both are fixed with the two buckling seats 2.

[0074] The two buckling seats 2 are connected to a driving member installed on the base 1, and the two clamping arms 3 are both installed with a vibrating member.

[0075] The two buckling seats 2 form a middle through slot for accommodating the trunk, and a plurality of support rods 202 are circumferentially and equidistantly hinged to the middle through slot. The support rods 202 are fixed with inoculation pads 201, and a plurality of discharge ports 207 are equidistantly arranged on the circumferences of the two buckling seats 2. The discharge ports 207 are communicated with a feeding assembly installed on the bottom of the base 1, and the feeding assembly is communicated with a impurity removal assembly installed on the bottom of the base 1.

[0076] In the application, when collecting seeds, the hydraulic mechanical arm drives the movement to the designated position, so that the two buckling seats 2 are located on both sides of the trunk. Then, the driving member drives the relative movement of the two buckling seats 2, and at the same time, the two clamping arms 3 move with the buckling seats 2.

[0077] When the two buckling seats 2 move relative to each other, the inoculation pads 201 on the buckling seats 2 and the inoculation pads 201 move synchronously. The movement of the two buckling seats 2 and the inoculation pads 201 forms a collecting hopper for collecting seeds.

[0078] Among them, the support rod 202 is reversibly arranged, which can be reversed and stored after the seed collection is completed.

[0079] When the two clamping arms 3 move to the end of the stroke, the trunk is clamped, and the vibration member generates vibration to make the seeds fall. The fallen seeds are collected through the collecting hopper, and then fall into the feeding assembly through the discharge port 207. The feeding assembly transports the seeds to the impurity removal assembly, and the impurity removal assembly removes the impurities mixed with the seeds to obtain relatively clean seeds.

[0080] The two buckling seats 2 are equidistantly arranged on the circumferences and are obliquely arranged with sliding holes 206. The sliding holes 206 are slidingly installed with sliding shafts 204, the end of the sliding shaft 204 is fixed with a spring 205, and the other end of the spring 205 is fixed with the bottom of the sliding hole 206.

[0081] The gap between two adjacent sliding shafts 204 is smaller than the diameter of the seed.

[0082] In the embodiment of the present application, the two clamping arms 3 are driven to move relative to each other when the two clamping seats 2 move relative to each other, and the clamping arms 3 need to clamp the tree trunk. In this way, the clamping seats 2 also clamp the tree trunk, which affects the transmission of vibration.

[0083] The solution of the embodiment is that the two clamping seats 2 are not in contact with the tree trunk when they move to abut, and the sliding shafts 204 elastically abut the tree trunk, thereby avoiding affecting the transmission of vibration. Since the sliding shafts 204 are in an inclined state, the seeds can be better driven to move towards the discharge port 207.

[0084] When the tree trunk vibrates, the sliding shafts 204 are driven to move axially, the spring 205 is compressed to store elastic potential energy, and the sliding shafts 204 are driven to reset by the elastic potential energy. Since the clamping seats 2 are not in contact with the tree trunk, there is a gap between the tree trunk and the clamping seats 2, and the sliding shafts 204 can fill the gap.

[0085] The driving member includes a bidirectional screw rod 503 rotatably installed on the base 1, and two threaded sleeves 502 are sleeved on the bidirectional screw rod 503 and threadedly matched with the bidirectional screw rod 503. The two threaded sleeves 502 are fixed with the two clamping seats 2, respectively.

[0086] The base 1 is fixed with a motor 5, and the output shaft of the motor 5 is connected with the bidirectional screw rod 503 through a third transmission chain 501.

[0087] In the embodiment of the present application, when the motor 5 works, the output shaft thereof drives the bidirectional screw rod 503 to rotate through the third transmission chain 501. When the bidirectional screw rod 503 rotates, the two threaded sleeves 502 and the two clamping seats 2 are driven to move relative to each other or in the opposite direction through the threaded matching.

[0088] Since seed collection is usually outdoor work, and outdoor power supply is usually a storage battery, in order to make the capacity of the storage battery unchanged, the motor 5 can work for a longer time. Since the embodiment adopts threaded transmission, a smaller power motor 5 can achieve the effect of energy saving. The torque required to drive the bidirectional screw rod 503 to rotate is relatively small, and therefore the motor 5 can adopt a smaller power motor.

[0089] The inoculation pad 201 is provided with a sandwich structure.

[0090] In the embodiment of the present application, the sandwich layer of the inoculation pad 201 is inflated by the air pumping device, so that the inoculation pad 201 is inflated.

[0091] Wherein, since the outside of the inoculation pad 201 is fixed with the support rod 202, the inside of the inoculation pad 201 is bulged when the inside of the inoculation pad 201 is inflated, the effect can reduce the shock when the seeds fall, some seeds are dropped after being collided with the shell after drying, and the subsequent processing of the seeds is affected, and the embodiment can effectively solve the problem.

[0092] The feeding assembly comprises a support 6 fixed to the bottom of the base 1, a concentration separation box 601 is fixed to the bottom of the support 6, two corrugated pipes 602 in communication with the concentration separation box 601 are fixed to the concentration separation box 601, two collection boxes 203 are respectively fixed to the bottom of the two buckle seats 2, the bottom of each of the two collection boxes 203 is inclined, and the ends of the two corrugated pipes 602 away from the concentration separation box 601 are in communication with the low positions of the two collection boxes 203;

[0093] The bottom of the concentration separation box 601 is inclined, and the high-position side of the bottom of the concentration separation box 601 is fixed with and in communication with the corrugated pipe 602;

[0094] The end of the concentration separation box 601 away from the corrugated pipe 602 is provided with an opening, and the opening end of the concentration separation box 601 is connected with the impurity removal assembly;

[0095] The bottom of the concentration separation box 601 is provided with two fans 603, the fan 603 is provided with a blade 604, the bottom of the concentration separation box 601 is provided with a ventilation hole 605, and the top of the concentration separation box 601 is provided with a removal opening 606.

[0096] In the embodiment of the application, after the seeds enter the collection box 203, the seeds move towards the low position of the bottom of the collection box 203 due to the inclined arrangement of the bottom of the collection box 203, so that the seeds in the collection box 203 enter the corrugated pipe 602 and are transported to the concentration separation box 601 through the corrugated pipe 602;

[0097] After the seeds enter the concentration separation box 601, the seeds move towards the low position due to the inclined arrangement of the bottom of the concentration separation box 601, so that the seeds move towards the opening end of the concentration separation box 601 and finally move to the impurity removal assembly;

[0098] When the fan 603 works, the blade 604 rotates, and when the blade 604 rotates, the wind force towards the removal opening 606 is generated, so that the powder impurities mixed in the seeds and the dry seeds are blown out through the removal opening 606 when the seeds pass through;

[0099] The ventilation hole 605 is used for blowing out the wind force, and the seeds cannot enter the fan 603;

[0100] It needs to be explained that when harvesting, the next seed is usually picked immediately after one is picked to ensure the efficiency of picking. The seeds are collected into the collection box 203 in a short time during picking. After picking is completed, the two buckle seats 2 and the collection box 203 are driven to move in opposite directions to release the picking state. When the two buckle seats 2 and the collection box 203 move in opposite directions, the bellows 602 is pulled up and bent under the pulling of the collection box 203, so that the collection box 203 is not interrupted when conveying to the concentration separation box 601 through the bellows 602.

[0101] Of course, a limiting piece for controlling the movement of the seeds is arranged at one end of the bellows 602 to control the amount of seed movement to avoid the accumulation of seeds in the concentration separation box 601, which causes the efficiency of blowing out the powder impurities.

[0102] The impurity removal assembly includes two baffles 4 fixed to the bottom of the base 1. Four first conveying rollers 403 are rotatably installed at the four corners of the two baffles 4. The four first conveying rollers 403 are connected by a conveying piece 402.

[0103] The conveying piece 402 is provided with a plurality of loading grooves 3014 equidistantly arranged thereon. The loading grooves 3014 cooperate with the concentration separation box 601. The bottom of each loading groove 3014 is provided with an inclined surface 3015. A separation piece is arranged in the conveying piece 402 and connected with one of the first conveying rollers 403.

[0104] The conveying piece 402 is provided with a limiting box 401 which is slidably connected with the bellows 602. The limiting box 401 is provided with a slot at each side. The slot at the side of the limiting box 401 facing the bellows 602 is located at the bottom, and the slot at the side of the limiting box 401 away from the bellows 602 is located at the top.

[0105] The slot at the bottom of the limiting box 401 cooperates with the concentration separation box 601, and the slot at the top of the limiting box 401 cooperates with the separation piece.

[0106] In the embodiment of the application, a high-torque motor is fixed to the bottom of the base 1. The output shaft of the motor is coaxially fixed with one of the first conveying rollers 403. When the motor works, the output shaft drives one of the first conveying rollers 403 to rotate, so as to convey the conveying piece 402 when one of the first conveying rollers 403 rotates, and simultaneously drive the remaining four first conveying rollers 403 to rotate.

[0107] As Figure 16As shown, when the conveying member 402 is conveying, the feeding groove 3014 on the conveying member 402 will be in turn coincided with the opening of the concentration and separation box 601, and the seeds in the concentration and separation box 601 will enter the feeding groove 3014 when coincided, and the seeds in the feeding groove 3014 will follow the conveying of the conveying member 402 and rise vertically, and will be discharged into the separation member when rising to the specified position;

[0108] The slot at the bottom of the limiting box 401 is used for abutting with the concentration and separation box 601, and simultaneously blocks the seeds in the concentration and separation box 601 from entering the feeding groove 3014, and the slot at the top of the limiting box 401 is used for abutting with the separation member, and blocks the direction of discharging;

[0109] The technical effect realized is that the seeds can be quantitatively and high-frequency discharged, for example, the amount of each time is about one jin, and the frequency is relatively large, so that the impurities in the seeds can be effectively separated by the separation mechanism, and the problem of accumulation and ineffective separation caused by uninterrupted and rapid discharging can be avoided.

[0110] Secondly, the structure of the present application for realizing the quantitative and high-frequency feeding is very simple, and only relies on the conveying of the conveying member 402, and compared with the existing quantitative discharging mechanism, the cost is very low, and the structure is simpler, and the existing quantitative discharging equipment is mostly made of metal materials, while the main part of the present application is the conveying member 402, and the conveying member 402 is made of high-strength flexible material and is more durable.

[0111] The separation member comprises a storage box 3011 fixed between the two baffles 4 and in the conveying member 402, and a second conveying roller 408 is rotatably installed on the inner side and the outer side of the storage box 3011 respectively, and the two second conveying rollers 408 are connected by a conveying belt 3012 in an inclined state;

[0112] The side of the storage box 3011 facing the bellows 602 is fixed with a guide member 3013 matched with the slot at the top of the limiting box 401, and the guide member 3013 is arranged in an inclined manner;

[0113] A plurality of hooks 3018 are fixed on the conveying belt 3012 along the conveying path at equal intervals, and a plurality of groups of through grooves 3017 are formed on the conveying belt 3012 along the conveying path at equal intervals;

[0114] A protection plate 3016 fixed with the storage box 3011 is arranged in the conveying belt 3012;

[0115] The side of the storage box 3011 facing the bellows 602 is fixed with a discharging member 3010, the conveying belt 3012 is in the discharging member 3010, and a discharging comb matched with the hooks 3018 is fixed in the discharging member 3010;

[0116] The second conveying roller 408 is connected to one of the first conveying rollers 403 through a transmission member.

[0117] In the embodiment of the present application, the transmission member comprises a first gear 405 and a second gear 406 which are rotatably installed on the baffle 4 and are engaged with each other, the first gear 405 is connected to the first conveying roller 403 through a first transmission chain 404, and the second gear 406 is connected to the second conveying roller 408 through a second transmission chain 407.

[0118] When the first conveying roller 403 rotates, the first gear 405 is driven to rotate through the first transmission chain 404, and the first gear 405 and the second gear 406 are relatively rotated through the engagement of the first gear 405 and the second gear 406, when the second gear 406 rotates, the second conveying roller 408 is driven to rotate through the second transmission chain 407, and the conveying belt 3012 is driven to convey when the second conveying roller 408 rotates; since the first gear 405 and the second gear 406 rotate in opposite directions, the conveying directions of the conveying member 402 and the conveying belt 3012 are opposite, and the conveying of the conveying belt 3012 is from low to high.

[0119] The seeds in the feeding groove 3014 are limited by the limiting box 401, and are thrown into the guide member 3013 under the driving of the inclined surface 3015. Since the guide member 3013 is inclined, the seeds are poured onto the conveying belt 3012, and the seeds on the conveying belt 3012 directly fall into the bottom of the storage box 3011 through the groove 3017, and some relatively large impurities are conveyed to the discharging member 3010 through the hook 3018, and finally fall into the discharging member 3010 and are discharged to the outside of the storage box 3011 through the discharging member 3010.

[0120] The unloading comb is used to remove the impurities stuck to the hook 3018, and has the same shape and function as a comb. The unloading comb is not shown in the figure.

[0121] It should be noted that the size of the groove 3017 can be changed according to the size of the collected seeds, because the seeds entering the storage box 3011 have completed the first wind selection and impurity removal, the impurities with relatively light weight are removed, and the remaining impurities are relatively heavy, such as leaves or branches, and the diameter of the groove 3017 can be relatively large, without being as dense as a screen.

[0122] The protective plate 3016 is used to limit the seeds to avoid being crushed by the conveying of the conveying belt 3012 on the second conveying roller 408.

[0123] The bottom of the storage box 3011 is inclined, and the storage box 3011 is provided with an outlet on the low position and the baffle 4, and the outlet is provided with a sealing plate 409 for sealing the outlet.

[0124] In the embodiment of the application, the opening or closing of the seed outlet is realized by driving the vertical sliding of the blocking plate 409.

[0125] The vibrating member comprises mounting grooves 301 formed on the two clamping arms 3, and an eccentric shaft 302 is rotatably mounted in the mounting grooves 301;

[0126] The eccentric shaft 302 comprises a shaft body and an eccentric block fixed to the shaft body.

[0127] The bottom of the baffle 4 is rotatably mounted with a transmission cylinder 305, two transmission rods 307 are slidably mounted in the transmission cylinder 305, a plurality of transmission bars 309 are fixed to the transmission rods 307, the transmission bars 309 are in sliding fit with transmission grooves 308 formed in the transmission cylinder 305, the transmission rods 307 are connected with the eccentric shaft 302 through a bevel gear set 303, and a follower plate 304 rotatably connected with the eccentric shaft 302 is further rotatably mounted on the transmission rod 307.

[0128] The transmission cylinder 305 is connected with one of the first conveying rollers 403 through a synchronous belt 306.

[0129] In the embodiment of the application, when the first conveying roller 403 rotates, the transmission cylinder 305 is driven to rotate through the synchronous belt 306, and in this process, a large pulley is arranged on the first conveying roller 403 and a small pulley is arranged on the transmission cylinder 305 to increase the speed.

[0130] When the transmission cylinder 305 rotates, the two transmission rods 307 are driven to rotate synchronously through the cooperation of the transmission bars 309 and the transmission grooves 308, the eccentric shaft 302 is driven to rotate through the bevel gear set 303 when the transmission rods 307 rotate, and the eccentric shaft 302 vibrates due to the eccentric block when the eccentric shaft 302 rotates. The vibration is transmitted to the clamping arms 3 and then to the tree trunk, so that the seeds are driven to fall off through the high-frequency vibration of the tree trunk.

[0131] Since the two clamping arms 3 move in opposite directions during construction or after construction, the movement of the two clamping arms 3 drives the two eccentric shafts 302 to move synchronously, the transmission rod 307 moves axially along the transmission cylinder 305 through the follower plate 304 when the eccentric shaft 302 moves, and since the transmission between the transmission cylinder 305 and the transmission rod 307 is realized 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.

[0132] It should be noted that the bevel gear set 303 comprises two bevel gears meshing with each other, and the two bevel gears are coaxially fixed with the transmission rod 307 and the eccentric shaft 302, respectively.

[0133] The application further provides a method for automatically collecting seeds of forest trees, which adopts the automatic seed collecting device of forest trees and comprises the following steps.

[0134] Step one, the base 1 is driven to move to a designated position by the hydraulic mechanical arm, and the two clamping arms 3 and the two buckling bases 2 are located on both sides of the trunk, then the two buckling bases 2 and the two clamping arms 3 are driven to move relatively, and the two clamping arms 3 clamp the trunk;

[0135] Step two, when the vibration member works, high-frequency vibration is generated to drive the seeds to fall through the seed collecting pad 201, the seeds falling into the seed collecting pad 201 fall into the collecting box 203, then the seeds are transported by the feeding assembly, and the powder and dust mixed in the seeds and the withered fruits are removed in the transportation process;

[0136] Step three, finally, the seeds are transported to the impurity removing assembly, the larger impurities in the seeds are removed, and finally, the clean seeds are obtained.
