In the implementation process of the invention: a certain amount of cut sugarcane seeds are placed into the seed guiding box 1, the sugarcane seeds enter the seed protecting tooth groove block 25 on the seed poking wheel 21 through the bottom outlet of the seed guiding box 1, the seed poking wheel 21 is driven to rotate under the action of gravity of the sugarcane seeds, the lower portion of the seed poking wheel 21 is driven to fall into the clamp holder 4 to be clamped tightly until the sugarcane seeds move, the clamp holder 4 releases the sugarcane seeds when the sugarcane seeds are transmitted to the position of the inlet of the seed sowing guide groove 8 through the driving of the driving belt 3, the sugarcane seeds fall into the seed sowing guide groove 8, and then the sugarcane seeds fall into the sugarcane planting ditch, and seed sowing is achieved.
The seed guide guard plate 22 and the seed protection tooth groove block 25 form a seed protection groove, so that the sugarcane seeds can smoothly rotate along with the seed poking wheel 21 without falling out;
wherein, the seed protection tooth groove block 25 is made of soft rubber material, which aims to reduce the scratch to the sugarcane seeds;
wherein the plastic pad 43 on the holder 4 is intended to reduce bruising of the clamping of the sugar cane seeds;
the size of a transverse outlet at the bottom of the seed guiding box 1 is adjustable to adapt to different varieties of sugarcanes which need to be cut into different sugarcane seed lengths, the adjustment can be carried out through two adjusting plates 12 movably arranged on the seed guiding box 1, the adjusting plates 12 can be adjusted through the adjusting rods 11, and specifically, circular holes in the adjusting rods 11 need to be inserted into different fixing columns 13 to enable the adjusting plates 12 to rotate to change the size of the outlet; meanwhile, the movable round rod 452 can extend and retract in the sleeve 451, so that the distance between the two sides of the holder 4 is changed to adapt to sugarcane seeds with different lengths; in addition, the spacing between the two seed-setting wheels 21 can be adjusted along the setting wheel shaft 23 to adapt to different lengths of sugarcane seeds;
wherein, the bottom outlet of the seed guide box 1 is set to pass through only one sugarcane seed but not two sugarcane seeds at the same time;
wherein, in order to ensure that the sugarcane seeds falling into each holder 4 are single, when the holder 4 moves to the position at the lower part of the seed poking wheel 21, the cylindrical poking rod 46 fixedly arranged at the top of the right holding rod 42 pokes the triangular boss 262 on the lever 261 to drive the lever 261 to rotate around the fulcrum, the clamping column 263 at the other end of the lever 261 is opened by overcoming the action of the return spring 264, so that the clamping column 263 leaves the seed protecting tooth socket block 25 on the seed poking wheel 21, at the moment, the seed poking wheel 21 rotates without being limited by the clamping column 263, and the single sugarcane seeds fall into the holder 4; after the clamp 4 carries the sugarcane seeds to continue to be transferred and leave the lower part of the seed poking wheel 21, the cylindrical poking rod 46 leaves the triangular boss 262, the lever 261 is driven to rotate under the action of the return spring 264, so that the clamping column 263 returns, the clamping column 263 blocks the rotation of the seed poking wheel 21 again, and the sugarcane seeds stop falling into the clamp 4;
wherein, in order to guarantee that the sugarcane kind can fall into holder 4 smoothly, need when holder 4 transmission to the setting wheel 21 bottom, left supporting rod 41 and right supporting rod 42 open, open process is: when the gripper 4 passes through the upper part of the seed taking cam, the supporting block 48 and the walking wheel 49 on the gripper 4 are pushed by the seed taking cam to move upwards, the supporting block 48 props the bottoms of the left clamping rod 41 and the right clamping rod 42, and the upper clamping parts of the left clamping rod 41 and the right clamping rod 42 are opened by overcoming the tension force of the contraction spring 47 so as to facilitate the sugarcane seeds to fall into the gripper 4;
wherein, in order to guarantee the sugarcane kind in data send process, prevent to cause the condition that the sugarcane drops to take place because reasons such as vibration, the slope of outside drive machine, holder 4 need press from both sides the sugarcane kind tightly after the sugarcane kind falls into, its clamping process is: when the clamp 4 leaves the upper part of the seed taking cam, the supporting block 48 and the travelling wheel 49 move downwards, the supporting block 48 leaves the bottoms of the left clamping rod 41 and the right clamping rod 42, and the upper clamping parts of the left clamping rod 41 and the right clamping rod 42 clamp the sugarcane seeds under the action of the contraction spring 47;
wherein, when the clamp 4 transmits the sugarcane seeds to the position of the inlet of the seed-metering guide groove 8, the process that the clamp 4 loosens the sugarcane seeds is as follows: when the clamp holder 4 is driven to the left lower part of the seed discharging cam, the supporting block 48 and the travelling wheel 49 on the clamp holder 4 are pushed by the seed discharging cam to move outwards, the supporting block 48 props the bottoms of the left clamping rod 41 and the right clamping rod 42, the upper clamping parts of the left clamping rod and the right clamping rod are opened by overcoming the tension of the contraction spring 47, and the sugarcane seeds are loosened and discharged into the inlet of the seed discharging guide groove 8;
in order to adjust the opening time and size of the clamping part of the clamp 4 conveniently, the two first telescopic rods connected with the seed taking cam are adjustable in length, the position of the seed taking cam can be changed by only adjusting the telescopic lengths of the two first telescopic rods, the time and distance of the upward movement of the support block 48 and the travelling wheel 49 which are pushed by the seed taking cam are changed, and the opening time and size of the clamping part of the clamp 4 are further adjusted; similarly, the position of the seed sowing cam can be changed by changing the telescopic lengths of the two second telescopic rods, and the opening time and the size of the clamping part of the clamp 4 can be adjusted, so that the time of the sugarcane seeds falling into the seed sowing guide groove 8 is changed;
in the sugarcane seed conveying process, in order to better match different seed sowing speeds, the power transmission part is set to be adjustable in speed, and the power transmission process is as follows: the driving fixed belt wheel 54 inputs power through an external power machine to drive the driving speed change belt wheel 51 to rotate, the driving speed change belt wheel 51 drives the driven speed change belt wheel 57 to rotate through a speed change belt, and then the driving gear 31 and the driven gear 32 are driven to rotate, so that the transmission process is realized; the speed regulation process is as follows: the width of the driving variable-speed belt wheel 51 is adjusted by changing the transmission ratio adjusting screw 53 on the boss 52, the distance of the variable-speed belt 56 hung on the driving variable-speed belt wheel 51 is changed, meanwhile, the distance of the driven variable-speed belt wheel 57 is changed, the transmission ratio is further changed, and stepless speed regulation is realized.
