Description

Technical Field

[0001] The invention relates to the technical field of seed collection, and in particular to a portable forest and grass seed collection device. Background Art

[0002] The method for collecting forest and grass seeds needs to be selected comprehensively based on seed characteristics, plant species, ecological protection requirements and laws and regulations.

[0003] For plants with clusters of honey locust hanging on branches, they are usually collected by beating them, and in the existing mechanical threshing, the branches and shells carried by them need to be removed after beating before the next seed collection can be carried out. However, this method has low efficiency in collecting seeds and cannot be collected continuously, which is too inconvenient.

[0004] For this situation, a method is needed to improve the efficiency of seed collection. To this end, we propose a portable forest and grass seed collection device. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a portable forest grass seed collection device to solve the problems raised in the above background technology.

[0006] A portable forest and grass seed collection device comprises a collection box, wherein the collection box is provided with a placement groove for convenient seed screening, wherein the placement groove is composed of two symmetrically arranged feed arc plates and a screening plate, and branches with seeds are placed on the screening plate for seed screening, and a screening shaft is rotatably connected in the placement groove; The screening shaft is provided with a rolling part and a vibrating part, and the collection box is provided with a driving motor, which can drive the screening shaft to rotate in a positive direction through a transmission mode; An energy storage gear rod is slidably connected to the collection box body, and the energy storage gear rod is used to make the sieve shaft rotate in the opposite direction when the driving motor is separated from the driving of the sieve shaft. A seed collecting frame and a branch frame are provided at the inner bottom of the collection box body.

[0007] Preferably, the driving motor is arranged on one side of the collection box, the output end of the driving motor is fixedly connected to the output shaft, the outer wall of the output shaft is fixedly provided with a transmission gear, the outer wall of the screening shaft is fixedly connected to a driven gear, and the driven gear and the transmission gear can mesh with each other.

[0008] Preferably, the number of teeth on the transmission gear is greater than that on the driven gear. The transmission gear is provided with a forward rotation part and a reverse rotation part. The forward rotation part is provided with teeth and can drive the driven gear to perform forward rotation. The reverse rotation part is not provided with teeth and does not play a transmission role on the driven gear when the transmission gear rotates.

[0009] Preferably, the energy storage rack bar and the transmission gear are arranged staggeredly, the driven gear is meshed with the energy storage rack bar, a return spring is arranged between the energy storage rack bar and the collection box body, and the return spring is used to drive the driven gear to rotate in the reverse direction.

[0010] Preferably, a plurality of screening holes corresponding to the size of the seeds are arranged on the screening plate. A moving frame body is arranged directly below the screening plate. The moving frame body and the screening plate are connected by a telescopic rod, and a vibration spring is arranged between the two. The moving frame body is slidably connected to the inner side wall of the collection box body, and the moving frame body can slide in the vertical direction; The seed collection frame and the moving frame body are arranged in an up-and-down manner. A pushing block is arranged on one side of the screening plate, and an oscillating pushing block is arranged on the pushing block.

[0011] Preferably, the rolling part includes two rotating rods arranged on the outer surface of the screening shaft. A rolling roller is rotatably connected between the two rotating rods. A ratchet wheel is arranged on one side of the rolling roller, and a ratchet pawl is arranged on the rotating rod corresponding to the ratchet wheel. When the screening shaft rotates forward, the ratchet pawl will not affect the rotation of the rolling roller; The vibration part includes a plurality of arc-shaped pushing blocks fixedly connected to the screening shaft. The positions of the arc-shaped pushing blocks correspond to the positions of the oscillating pushing blocks. When the screening shaft rotates forward, the screening plate is driven to vibrate by the arc-shaped pushing blocks.

[0012] Preferably, a stretching rod is fixedly connected to the moving frame body, and the stretching rod penetrates through the top of the collection box body on the screening plate and extends; The energy storage rack bar and the stretching rod are connected by a transmission rod. When the energy storage rack bar is reset, it drives the screening plate and the moving frame body to move downward as a whole. At this time, there will be a certain distance between the screening plate and the blanking arc plate. The upper surface of the screening plate is arranged in an inclined manner, and the distance generated between the screening plate and the blanking arc plate corresponds to the bottom end position of the inclined surface of the screening plate.

[0013] Preferably, the branch frame is used to collect the branches after screening the seeds, and the branch frame is located on one side of the bottom end of the inclined surface of the screening plate.

[0014] The beneficial effects of the present invention are as follows: 1. In this solution, through the arranged screening shaft and the rolling part and vibration part arranged on its surface, when the screening shaft rotates, the rolling part therein can roll the branches with seeds on the screening plate, so that the seeds are separated from the branches. After the seeds are separated, the vibration part therein can also push the pushing block, and under the action of the vibration spring, the screening plate and the moving frame body can move relatively repeatedly, so as to prevent the separated seeds from being blocked by the branches and unable to enter the seed collection frame, thereby realizing the separation effect of the seeds.

[0015] 2. In this solution, through the transmission gear provided, when the forward rotation part on the transmission gear drives the driven gear to rotate, the effect of separating and screening seeds can be achieved. Moreover, the reverse rotation part among them will not cause the driven gear to rotate. The driven gear will reverse under the action of the return spring, and the return spring will also cause the energy storage tooth bar to move. The energy storage tooth bar can drive the screening plate and the moving frame body to move downward as a whole, so that a gap appears between the screening plate and the blanking arc plate. As a result, when the rolling part rotates in reverse, the screened branches will be pushed into the branch frame through this gap, so as to continuously screen the seeds.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, each embodiment of the present invention will be described in detail with reference to the attached Figures 1 to 7 Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. Embodiment 1

[0019] A portable forest and grass seed collection device includes a collection box body 1. A placement groove for facilitating the screening of seeds is provided inside the collection box body 1. The placement groove is composed of two symmetrically arranged blanking arc plates 8 and a screening plate 12. When screening seeds from branches with seeds, the branches are placed on the screening plate 12, and at this time, the branches should be within the placement groove.

[0020] Refer to the appendix Figure 2 Inside the placement groove, a screening shaft 5 is rotatably connected. A rolling part 10 and a vibrating part 11 are provided on the screening shaft 5. A driving motor 2 is provided on the collection box body 1, and the driving motor 2 can drive the screening shaft 5 to rotate forward through a transmission method.

[0021] Refer to the appendix Figure 5 The rolling part 10 includes two rotating rods arranged on the outer surface of the screening shaft 5. A rolling roller 20 is rotatably connected between the two rotating rods. A ratchet wheel 18 is provided on one side of the rolling roller 20, and a ratchet pawl 19 is provided on the rotating rod corresponding to the ratchet wheel 18. When the screening shaft 5 rotates forward, the ratchet pawl 19 does not affect the rotation of the rolling roller 20. The ratchet pawl 19 is set to limit the rolling roller 20 to only rotate forward. Its function is: when the screening shaft 5 rotates forward, when the rolling roller 20 contacts the branches, it can still rotate under the action of friction, and at this time, the branches can be rolled to improve the seed detachment efficiency. When the screening shaft 5 rotates in the reverse direction, under the action of the ratchet pawl 19 and the ratchet wheel 18, the rolling roller 20 will not rotate, so as to scrape out the branches after screening the seeds.

[0022] The vibrating part 11 includes a plurality of arc-shaped push blocks 21 fixedly connected to the screening shaft 5. The positions of the arc-shaped push blocks 21 correspond to the positions of the oscillating push blocks 22. When the screening shaft 5 rotates forward, the arc-shaped push blocks 21 drive the screening plate 12 to vibrate.

[0023] Refer to the appendix Figure 4 When the screening shaft 5 rotates forward, when the arc-shaped push blocks 21 rotate, they will contact the oscillating push blocks 22, and the oscillating push blocks 22 will drive the screening plate 12 to move relative to the moving frame body 13. And under the combined action of the vibration springs 16, the screening plate 12 vibrates, so that the seeds separated from the branches can move down and be conveniently collected through the screening plate 12. Embodiment 2

[0024] Refer to the appendix Figure 2 A storage tooth rod 7 is slidably connected to the collection box body 1. The storage tooth rod 7 is used to make the screening shaft 5 rotate in the reverse direction when the driving motor 2 disengages from driving the screening shaft 5.

[0025] The driving motor 2 is arranged on one side of the collection box body 1. The output end of the driving motor 2 is fixedly connected with an output shaft 3. A transmission gear 4 is fixedly arranged on the outer side wall of the output shaft 3. A driven gear 6 is fixedly connected to the outer side wall of the screening material shaft 5. The driven gear 6 and the transmission gear 4 can mesh with each other.

[0026] Refer to the appendix Figure 6 , the number of teeth of the transmission gear 4 is more than that of the driven gear 6. The transmission gear 4 is provided with a forward rotation part 401 and a reverse rotation part 402. The forward rotation part 401 is provided with teeth and can drive the driven gear 6 to perform a forward rotation movement. The reverse rotation part 402 is not provided with teeth and cannot play a transmission role on the driven gear 6 when the transmission gear 4 rotates.

[0027] Specifically, when the driving motor 2 drives the output shaft 3 to rotate, the transmission gear 4 is synchronously driven to rotate. The teeth on the forward rotation part 401 of the transmission gear 4 will mesh with the driven gear 4, thereby driving the driven gear 4 to rotate. At this time, the rotation of the transmission gear 4 will drive the screening material shaft 5 to rotate forward. When the reverse rotation part 402 rotates to a position corresponding to the driven gear 4, the driven gear 4 will not be affected by the transmission of the driven gear 4.

[0028] Refer to the appendix Figure 2 - Appendix Figure 3 , the energy storage tooth bar 7 and the transmission gear 4 are arranged in an interleaved manner. The driven gear 6 and the energy storage tooth bar 7 are meshed and connected. A return spring 9 is arranged between the energy storage tooth bar 7 and the collection box body 1. The return spring 9 is used to drive the driven gear 6 to rotate in the reverse direction.

[0029] When the forward rotation part 401 of the transmission gear 4 drives the driven gear 6 to rotate forward, the driven gear 6 will cause the energy storage tooth bar 7 to move in position. At this time, the return spring 9 will be stretched. When the energy storage tooth bar 7 moves a certain distance, it will not continue to move. When the forward rotation part 401 is disengaged from the driven gear 6, the reverse rotation part 402 on the transmission gear 4 will not limit the position of the driven gear 6. At this time, the return spring 9 will perform a reset action and pull the energy storage tooth bar 7, making it have a tendency to reset. When the energy storage tooth bar 7 moves, it will push the driven gear 6 to rotate in the reverse direction. At this time, the driven gear 6 will drive the screening material shaft 5 to rotate in the reverse direction.

[0030] It should be noted that when the branch with seeds is placed in the placement groove, the forward rotation part 401 will first drive the driven gear 6 to rotate, thereby causing the screening shaft 5 to rotate forward. The seeds on the branch are screened out through the rolling part 10 and the vibration part 11. (When the rolling roller 20 rotates, although the screening plate 12 will move down a certain distance, the screening plate 12 will not be lower than the bottom end of the blanking arc plate 8, so as to prevent the branch from being pushed below the screening plate 12 before the seeds are completely screened.) When the screening shaft 5 rotates reversely under the action of the energy storage tooth rod 7, the screening shaft 5 will reverse. Through the above description, the rolling roller 20 on the screening shaft 5 will push the branch after seed screening to one side.

[0031] A plurality of screening holes 15 corresponding to the size of the seeds are provided on the screening plate 12. A moving frame body 13 is provided directly below the screening plate 12. The moving frame body 13 and the screening plate 12 are connected by a telescopic rod, and a vibration spring 16 is provided between the two. The moving frame body 13 is slidably connected to the inner side wall of the collection box body 1, and the moving frame body 13 can slide in the vertical direction.

[0032] The size of the screening holes 15 should correspond to the size of the seeds to be screened. The vibration spring 16 is provided so that after the screening plate 12 is pressed down, it can reset, so as to achieve the effect of jitter and facilitate the screening of seeds. Moreover, when discharging the screened branches, the position of the moving frame body 13 will move. When the moving frame body 13 moves, the position of the screening plate 12 will also move synchronously.

[0033] The seed collection frame 23 and the moving frame body 13 are arranged vertically. A pushing block 17 is provided on one side of the screening plate 12, and an oscillating pushing block 22 is provided on the pushing block 17. The top surface of the oscillating pushing block 22 is arranged in an arc shape. This arrangement is to facilitate the arc-shaped pushing block 21 to push the oscillating pushing block 22. When the moving frame body 13 moves to the maximum height, the arc surface on the arc-shaped pushing block 21 can contact the arc surface at the top of the oscillating pushing block 22. Under the action of the component force of the rotation of the arc-shaped pushing block 21, the pushing block 17 and the screening plate 12 as a whole move down (at this time, the vibration spring 16 is compressed, and during the downward movement of the screening plate 12, the elastic potential energy of the vibration spring 16 continuously increases). After the screening plate 12 moves down as a whole, the arc-shaped pushing block 21 continues to rotate. When the next arc-shaped pushing block 21 does not contact the oscillating pushing block 22 during rotation, the screening plate 12 will reset under the action of the vibration spring 16, and then when the next arc-shaped pushing block 21 contacts the oscillating pushing block 22 again, it will move down again, and then the screening plate 12 will reset under the action of the vibration spring 16 again. Thus, the vibration of the screening plate 12 is realized, and the seeds separated from the branches are screened down from the screening plate 12. Embodiment 3

[0034] A stretching rod 14 is fixedly connected to the moving frame body 13, and the stretching rod 14 penetrates through the top of the collecting box body 1 on the screening plate 12 and extends. When screening the seeds on the branches, the stretching rod 14 will drive the moving frame body 13 to move up to a fixed position. Correspondingly, the energy storage rack bar 7 is also moved to a fixed position at this time.

[0035] The energy storage rack bar 7 is connected to the stretching rod 14 through a transmission rod. When the reverse part 402 corresponds to the driven gear 6, the energy storage rack bar 7 will be reset under the action of the return spring 9. When the energy storage rack bar 7 is reset, it drives the screening plate 12 and the moving frame body 13 to move down as a whole. At this time, there will be a certain distance between the screening plate 12 and the blanking arc plate 8. When the energy storage rack bar 7 moves and resets, the energy storage rack bar 7 will make the stretching rod 14 move down through the transmission rod, so that the screening plate 12 and the moving frame body 13 can move down as a whole. At this time, there will be a gap between the screening plate 12 and the blanking arc plate 8. When the screening shaft 5 rotates in reverse, the rolling roller 20 will rotate in the reverse direction as a whole (the rolling roller 20 will not rotate in the reverse direction under the action of the pawl 19, so as to increase the friction force with the branches and facilitate pushing them off the screening plate 12). The branches on the screening plate 12 are pushed into the branch frame 24 by the rolling roller 20, and the treatment of the branches after screening out the seeds is completed.

[0036] After the branches after screening the seeds are pushed out, since the transmission gear 4 is continuously rotating, when the forward rotation part 401 on the transmission gear 4 contacts the driven gear 6 (the energy storage rack bar 7 will move under the action of the driven gear 6 again, so as to drive the moving frame body 13 to move to its highest position), then branches that need to be screened for seeds are added to the placement groove, so as to continuously screen the seeds on the branches.

[0037] A seed collecting frame 23 and a branch frame 24 are provided at the inner bottom of the collecting box body 1. The branch frame 24 is used to collect the branches after screening the seeds, and the branch frame 24 is located on one side of the bottom end of the inclined surface of the screening plate 12.

[0038] Refer to the Figure 4 screening plate 12 in the appendix. The upper surface of the screening plate 12 is arranged in an inclined manner, and the distance generated between the screening plate 12 and the blanking arc plate 8 corresponds to the bottom end position of the inclined surface of the screening plate 12. In this way, it is convenient for the rolling roller 20 to push the branches when rotating in reverse, and it is convenient to push out the branches.
