DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1: A potato breeding field seeder, such as Figure 1-Figure 5As shown, it includes a vehicle body 1, a support frame 101, a lifting plate 102, a limit plate 1021, a driven frame 103, a first tension spring 104, a turntable 105, a support frame 106, a soil taking clamping plate 107, a rear support plate 108, a material blocking plate 109, a sowing tube 112, a side plate 113 and a blocking rod 114. The top of the vehicle body 1 is symmetrically fixed with two support frames 101, and the support frame 101 is composed of two vertical legs and an inverted T-shaped bracket. The T-shaped bracket is fixed to the top of the two legs. A slideway is opened on the inner wall of the support frame 101 in the vertical direction. The lift plates 102 are slidably connected in the slideways of the two support frames 101. The lift plates 102 are connected together. 02 is symmetrically connected to two limit plates 1021 for sliding movement. The limit plates 1021 slide in the vertical direction, and a first tension spring 104 is sleeved on the guide rod of the limit plate 1021. The upper end of the first tension spring 104 is fixedly connected to the lifting plate 102, and the lower end of the first tension spring 104 is fixedly connected to the limit plate 1021. When the lifting plate 102 moves upward, the limit plate 1021 is driven to move upward through the first tension spring 104. When the limit plate 1021 moves upward to a set height, it will be blocked by the T-shaped bracket of the support frame 101. A driven frame 103 is fixedly connected to the two limit plates 1021. The driven frame 103 is located at the lower side of the lifting plate 102. There are two turntables 105 connected to the upper coaxial rotation, and the adjacent ends of the two turntables 105 are fixedly connected to a support frame 106. The adjacent sides of the two support frames 106 are fixedly connected by a straight rod. Two soil-taking clamping plates 107 are symmetrically slidably connected in each support frame 106. The soil-taking clamping plates 107 are used to insert and clamp soil to realize the function of digging a pit. The lower ends of the soil-taking clamping plates 107 and the support frames 106 are both toothed for cutting the film. When the limit plate 1021 is blocked by the T-shaped bracket of the support frame 101, the soil-taking clamping plates 107 are located above the film. A rear support plate 108 is fixedly connected to the vehicle body 1, and two material blocking plates 109 are symmetrically fixedly connected to the rear support plate 108. Two sowing tubes 112 are slidably connected to the rear support plate 108. The sowing tubes 112 are used to sow seeds into the dug pits. The baffle plate 109 is used to prevent the seeds in the sowing tubes 112 from falling out. The two sowing tubes 112 are fixedly connected to the opposite sides with side plates 113. A baffle rod 114 is fixedly connected to the side of the turntable 105 away from the support frame 106. The baffle rod 114 and the support frame 106 are both located at the eccentric position of the turntable 105. The baffle rod 114 and the side plate 113 cooperate with each other. During the rotation of the turntable 105, the baffle rod 114 can push the sowing tube 112 away from the top of the baffle plate 109 through the side plate 113, so that the seeds in the sowing tube 112 are sown into the pits.

[0028] The vehicle body 1 is controlled to move intermittently along the ridge. When the lifting plate 102 is at the top, the first tension spring 104 is in a stretched state. At this time, the support frame 106 is located on the upper side of the turntable 105, the blocking rod 114 is located on the lower side of the turntable 105, and the sowing tube 112 is in a state of being moved away from the blocking plate 109. The figure shows a state in which the limit plate 1021 just contacts the support frame 101. In this state, the lifting plate 102 can continue to move upward; when the vehicle body 1 stops, the lifting plate 102 is controlled to move downward. Since the first tension spring 104 is in a pulled state, the lifting plate 10 At the beginning of the downward movement, the limit plate 1021 and the driven frame 103 will remain stationary, so that the lifting plate 102 will first approach the driven frame 103. During this process, the turntable 105 will reverse 180 degrees, and the support frame 106 will be rotated to the lower side, the blocking rod 114 will be rotated to the upper side, and the sowing tube 112 will be reset to the top of the blocking plate 109. Then the lifting plate 102 drives the driven frame 103 to move downward synchronously, and the driven frame 103 drives the support frame 106 and the soil-taking clamping plate 107 to cut the film downward and insert it into the soil of the field ridge. The support frame 106 and the soil-taking clamping plate The teeth at the lower end of 107 can quickly pierce and cut the film. When the limit plate 1021 is about to drop to contact with the vehicle body 1, the two soil-taking clamping plates 107 in the same support frame 106 start to move relative to each other to clamp the soil, and then the lifting plate 102 drives the driven frame 103 to move upward, thereby driving the soil-taking clamping plates 107 to take out the soil, so that a cylindrical pit is dug on the ridge. When the support frame 106 and the soil-taking clamping plates 107 rise above the film, the limit plate 1021 will be blocked by the support frame 101, so that the limit plate 1021 and the driven frame 103 It no longer moves upward, but the lifting plate 102 still moves upward. During the continued upward movement of the lifting plate 102, the first tension spring 104 will be stretched, and in this process, the turntable 105 will rotate 180 degrees clockwise, and the support frame 106 and the soil-taking clamping plate 107 will be rotated to the upper side. When the turntable 105 rotates, it will push the side plate 113 through the baffle rod 114, so that the side plate 113 drives the sowing tube 112 to move away from above the baffle plate 109 and move to above the pit, so as to put the seeds into the sowing tube 112 in advance, so that the seeds can accurately fall into the pit for sowing.

[0029] like Figure 2 and Figure 4 As shown, it also includes a flip gear 2 and a flip rack 201 for driving the turntable 105 to rotate. The flip gear 2 is fixedly connected to the common rotation axis of the two turntables 105, and two flip racks 201 are symmetrically fixedly connected to the lifting plate 102. The flip rack 201 is meshed with the flip gear 2.

[0030] When the lifting plate 102 moves, the flip rack 201 will be driven to move synchronously. When the limit plate 1021 contacts the support frame 101, it can no longer move upward. When the lifting plate 102 continues to move upward, the flip rack 201 will drive the turntable 105 to rotate 180 degrees forward through the flip gear 2. When the lifting plate 102 approaches the driven frame 103, the flip rack 201 will drive the turntable 105 to rotate 180 degrees in the opposite direction through the flip gear 2.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a driving mechanism for driving the soil taking clamping plate 107 to clamp soil. The driving mechanism is connected to the soil taking clamping plate 107. The driving mechanism includes a small bracket 3, a No. 2 spring 301, a shrinkage block 302, an extrusion plate 303 and a locking assembly. Two small brackets 3 are symmetrically slidably connected to the support frame 106. The small bracket 3 is fixedly connected to an adjacent soil taking clamping plate 107. A No. 2 spring 301 is sleeved on the guide rod of the small bracket 3. When the two soil taking clamping plates 107 move relative to each other, the No. 2 spring 301 will be compressed. The shrinkage block 302 is fixedly connected to the small bracket 3. Two extrusion plates 303 are fixedly connected to the vehicle body 1. The extrusion plate 303 is located below the support frame 106. During the downward movement of the support frame 106 and the soil taking clamping plate 107, the extrusion plate 303 squeezes the shrinkage block 302 to make the two soil taking clamping plates 107 move relative to each other to clamp soil. A locking assembly for locking the soil taking clamping plate 107 is connected to the support frame 106.

[0032] When the limit plate 1021 is about to drop to contact the vehicle body 1, the extrusion plate 303 begins to contact the shrinkage block 302. The extrusion plate 303 will squeeze the shrinkage block 302 to make the soil taking clamping plate 107 move relative to clamp the soil. The soil taking clamping plate 107 will compress the No. 2 spring 301 when it moves relative to the vehicle body 1. The locking assembly will limit the soil taking clamping plate 107 from loosening its grip on the soil. During the forward rotation of the turntable 105, the locking assembly will cancel the restriction on the soil taking clamping plate 107, so that the soil taking clamping plate 107 can be reset under the push of the No. 2 spring 301.

[0033] like Figure 2 and Figure 3As shown, the locking assembly includes a locking frame 304, a second tension spring 305, a linkage rod 306, an unlocking shaft 307 and an unlocking rod 308. The locking frame 304 is slidably connected to the straight rod fixed between the two support frames 106 in the vertical direction. The second tension spring 305 is sleeved on the guide rod of the locking frame 304. The upper end of the second tension spring 305 is fixed to the locking frame 304, and the lower end of the second tension spring 305 is fixed to the straight rod fixed between the two support frames 106. A linkage rod 306 is fixedly connected to the two soil-taking clamps 107 on the side, and a locking frame 304 is used to be clamped on the outside of the linkage rod 306 to limit the soil-taking clamps 107 from loosening the soil. An unlocking shaft 307 is fixedly connected to the locking frame 304, and an unlocking rod 308 is fixedly connected to the driven frame 103. During the rotation of the turntable 105, the unlocking rod 308 will squeeze the unlocking shaft 307 in the direction away from the support frame 106 to drive the locking frame 304 to cancel the restriction on the linkage rod 306.

[0034] The second tension spring 305 shown in the figure is in a stretched state. When the soil taking splint 107 moves relative to each other, it will drive the linkage rod 306 to move synchronously. When the soil taking splint 107 clamps the soil, the second tension spring 305 will drive the locking frame 304 to move downward, and the locking frame 304 will move to the side of the linkage rod 306 to limit the soil taking splint 107 from moving away from each other. When the turntable 105 is about to rotate 180 degrees forward, the unlocking rod 308 will contact the unlocking shaft 307, and the unlocking rod 308 will squeeze the unlocking shaft 307 to make the locking frame 304 move away from the linkage rod 306, and the second tension spring 305 will be stretched again. When the locking frame 304 moves away from the two sides of the linkage rod 306, the No. 2 spring 301 pushes the soil taking splint 107 and the linkage rod 306 to reset. The reset linkage rod 306 will prevent the locking frame 304 from resetting under the action of the second tension spring 305.

[0035] like Figure 5 As shown, it also includes a connecting frame 110 and a No. 1 spring 111 for driving the sowing tube 112 to reset. The connecting frame 110 is slidably connected to the rear support plate 108 in the horizontal direction. The No. 1 spring 111 is sleeved on the guide rod of the connecting frame 110. The connecting frame 110 is located between the two sowing tubes 112, and the connecting frame 110 and the two sowing tubes 112 are fixedly connected. When the blocking rod 114 pushes the sowing tube 112 to move through the side plate 113, the No. 1 spring 111 will be compressed.

[0036] When the blocking rod 114 drives the sowing tube 112 to move away from the top of the blocking plate 109 through the side plate 113, the No. 1 spring 111 will be compressed. When the turntable 105 reverses and resets, the blocking rod 114 will be driven away from the side plate 113, so that the sowing tube 112 can be reset under the action of the No. 1 spring 111.

[0037] Embodiment 2: Based on embodiment 1, Figure 4-Figure 6As shown, it also includes a delivery mechanism for automatically delivering seeds into the sowing tube 112, the delivery mechanism is installed on the vehicle body 1, the delivery mechanism includes a storage box 4, a sprocket 401, a chain 402 and a feeding ring 403, the vehicle body 1 is fixedly connected with a storage box 4 for storing seeds, one end of the storage box 4 close to the sowing tube 112 is rotatably connected with four sprockets 401, the four sprockets 401 are distributed in a mouth shape, and a chain 402 is wound around the two sprockets 401 on the same side on the left and right sides, and two feeding rings 403 distributed in a ring array are fixedly connected to the chain 402, and the feeding ring 403 can lift the seeds upward from the bottom of the storage box 4 during the rotation of the chain 402, and the feeding ring 403 is used to take out the seeds in the storage box 4 and deliver them into the sowing tube 112, and two feeding holes 404 are symmetrically provided on the storage box 4, and the feeding ring 403 can pass through the feeding holes 404.

[0038] The seeds refer to the original potato seeds that have been screened and graded according to size specifications. The seeds to be planted are poured into the storage box 4 in advance, and the diameter of the seeds is larger than the diameter of the feeding hole 404, so the seeds cannot fall out of the feeding hole 404. In the first half of the turntable 105 rotating 180 degrees, the sprocket 401 drives the chain 402 to rotate, and the chain 402 drives the feeding ring 403 located below the storage box 4 to move upward. The feeding ring 403 can support the bottom of the seeds during the upward movement and transport the seeds upward to the upper side of the sowing tube 112, so that the seeds can fall into the sowing tube 112 and be blocked by the baffle plate 109.

[0039] like Figure 4 and Figure 5 As shown, it also includes a transmission shaft 5, a transmission gear 501 and a transmission rack 502 for driving the sprocket 401 to rotate. The sprocket 401 located on the upper side is fixedly connected with the transmission shaft 5. The end of the transmission shaft 5 away from the sprocket 401 extends toward the turntable 105, and the end extending toward the turntable 105 is rotatably connected to the transmission gear 501 through a one-way bearing. The end of the turntable 105 close to the transmission shaft 5 is fixedly connected with a transmission rack 502. The transmission rack 502 is arc-shaped to match the rotation path of the turntable 105. The transmission rack 502 can engage with the transmission gear 501 during the rotation of the turntable 105.

[0040] During the forward rotation of the turntable 105, the transmission rack 502 will drive the transmission gear 501 to rotate, and the transmission gear 501 will drive the sprocket 401 to rotate through the transmission shaft 5; during the reverse rotation of the turntable 105, since the transmission gear 501 is installed on the transmission shaft 5 through a one-way bearing, the transmission gear 501 will not drive the transmission shaft 5 to rotate through the one-way bearing.

[0041] Embodiment 3: Based on embodiment 2, Figure 6 and Figure 7As shown, it also includes a filling mechanism for filling soil into the pit, the filling mechanism includes a filling box 6, a force plate 601, a No. 3 spring 602, a support rod 603, a flat baffle 604, an inclined baffle 605, a stop guide tube 606, a guide tube 607 and a thrust rod 608, two filling boxes 6 are fixedly connected to the two support frames 101, a through hole for soil to flow out is opened on the lower end surface of the filling box 6, the filling box 6 is slidably connected with the force plate 601 in the vertical direction, the guide rod of the force plate 601 is sleeved with a No. 3 spring 602, the force plate 601 will compress the No. 3 spring 602 during the downward movement, the lower end of the force plate 601 is fixedly connected to the support rod 603, and the middle part of the support rod 603 is fixedly connected to the flat baffle 604, The flat baffle 604 is in the shape of a circular plate, and an inclined baffle 605 is fixedly connected to the lower end of the support rod 603.

A stop guide tube 606 is fixedly connected to the through hole at the lower end of the filling box 6, and a guide tube 607 is fixedly connected to the stop guide tube 606. After the inclined baffle 605 contacts the bottom end of the stop guide tube 606, the soil between the inclined baffle 605 and the flat baffle 604 can enter the pit through the guide tube 607. A thrust rod 608 is fixedly connected to the lifting plate 102, and the thrust rod 608 is used to press the force plate 601 downward.

[0042] When the force plate 601 does not move downward, the oblique baffle 605 is located in the through hole at the bottom of the filling box 6, and the oblique baffle 605 prevents the soil in the filling box 6 from flowing out. After the turntable 105 is reversed and reset, the vehicle body 1 is controlled to move forward. When the lower end of the guide pipe 607 moves to the top of the pit, the movement of the vehicle body 1 is stopped, and then the lifting plate 102 is controlled to move downward to dig a pit at the next position, and the lifting plate 102 presses the force plate 601 downward through the thrust rod 608, and the force plate 601 drives the flat baffle 604 and the oblique baffle 605 to move forward. When the lifting plate 102 moves upward, the soil in the filling box 6 will flow into the stop tube 606. When the inclined baffle 605 contacts the bottom of the stop tube 606, the flat baffle 604 moves to the through hole at the bottom of the filling box 6, so that the soil in the filling box 6 cannot continue to flow out, and the soil between the flat baffle 604 and the inclined baffle 605 will flow into the dug pit through the guide tube 607. When the lifting plate 102 moves upward, the No. 3 spring 602 will push the force plate 601 to reset upward, and the flat baffle 604 and the inclined baffle 605 will also rise and reset synchronously.

[0044] When the turntable 105 rotates forward 180 degrees, it will drive the soil-taking clamping plate 107 to move above the conveying pipe 7. When the soil-taking clamping plate 107 releases the clamping of the soil, the soil will fall downward into the conveying pipe 7. When the turntable 105 rotates forward, the control motor 703 drives the spiral blade 701 to rotate, and the spiral blade 701 will transport the soil that falls into the conveying pipe 7 to the filling box 6.
