Description

Technical Field

[0001] This utility model relates to the field of automatic seeding technology, and in particular to a seed storage device. Background Technology

[0002] In agriculture, seeders are commonly used for sowing. Current seeders typically use intermittently opening and closing the discharge port to release seeds in batches for sowing. However, factors such as seed shape, stacking height, and friction result in varying amounts of seeds falling in different batches, making quantitative sowing difficult. Utility Model Content

[0003] To address the aforementioned problems, this technical solution provides a seed storage device.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A seed storage device, comprising

[0006] A grain bin, used for storing seeds;

[0007] The hopper body is provided with an inlet and an outlet that communicate with the hopper.

[0008] A discharge mechanism is provided inside the hopper and is used to quantitatively transport the seeds at the inlet to the outlet; the discharge mechanism includes a discharge shaft connected to a power source, a discharge cylinder provided on the discharge shaft, and a quantitative hopper recessed on the discharge cylinder; the discharge cylinder is provided close to the outlet to separate the inlet and the outlet;

[0009] When the quantitative hopper passes the inlet, the seeds in the hopper fall into the quantitative hopper and rotate with the quantitative hopper to the outlet for discharge.

[0010] The seed storage device described above also includes an adjustment mechanism for adjusting the capacity of the quantitative storage bin.

[0011] As described above, in a seed storage device, the adjustment mechanism includes an adjustment wheel disposed on the discharge shaft, an adjustment block embedded in the quantitative storage bin, and an adjustment assembly disposed between the adjustment wheel and the adjustment block. The adjustment wheel drives the adjustment block to move along the length direction of the quantitative storage bin to reduce or increase the space occupied by the quantitative storage bin.

[0012] As described above, in a seed bin device, the adjusting component includes a first rotating sleeve sleeved on the discharge shaft and rotating synchronously with the adjusting wheel, and a second rotating sleeve threadedly engaged with the first rotating sleeve. The adjusting block is disposed on the second rotating sleeve. When the adjusting wheel rotates around the discharge shaft, the first rotating sleeve rotates relative to the second rotating sleeve, thereby driving the adjusting block to move along the axial direction of the discharge shaft, thereby adjusting the insertion depth into the quantitative bin.

[0013] In the seed storage device described above, a plurality of quantitative bins are evenly spaced along the circumferential direction of the discharge cylinder, and a plurality of adjusting blocks are evenly spaced along the circumferential direction of the second rotating sleeve, with each quantitative bin corresponding to one of the adjusting blocks.

[0014] In the seed storage device described above, the adjusting block is kept inserted into the metering chamber so that the discharge cylinder and the second rotating sleeve rotate synchronously.

[0015] As described above, in a seed storage device, the adjustment mechanism further includes a switching component. The switching component is used to make the discharge cylinder rotate synchronously with the first rotating sleeve, so that all three rotate synchronously with the second rotating sleeve to maintain the space occupied by the adjustment block; or to make the first rotating sleeve and the second rotating sleeve rotate relative to each other to adjust the space occupied by the adjustment block.

[0016] As described above, in a seed storage device, the switching component includes pre-tightening springs at both ends pressing against the discharge cylinder and the first rotating sleeve respectively. When the discharge shaft drives the discharge cylinder to rotate, the first rotating sleeve is pressed by the pre-tightening springs so that the first rotating sleeve rotates synchronously with the discharge cylinder. When the adjusting wheel drives the first rotating sleeve to rotate, the first rotating sleeve overcomes the pressing force of the pre-tightening springs and rotates relative to the second rotating sleeve.

[0017] The seed storage device described above further includes an anti-crushing mechanism for confining seeds outside the quantitative storage bin at the feed inlet.

[0018] As described above, in a seed storage device, the anti-crushing mechanism includes a brush head disposed within the storage chamber and bristles disposed on the brush head. The bristles abut against the outer wall of the discharge cylinder. When the quantitative storage chamber leaves the inlet after passing through the bristles, the bristles trap the seeds outside the quantitative storage chamber at the inlet.

[0019] The beneficial effects of this application are:

[0020] This utility model provides a seed storage device. In use, seeds are first placed in the storage hopper. After passing through the inlet, the seeds fall into the quantitative storage hopper. When the discharge shaft rotates, it drives the discharge cylinder to rotate, causing the quantitative storage hopper to rotate to the discharge outlet and be discharged. Since the seeds outside the quantitative storage hopper are blocked by the inlet, they cannot enter the discharge outlet. Only the seeds in the quantitative storage hopper can pass through, thereby achieving the effect of quantitative sowing. Attached Figure Description

[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] A seed storage device, comprising

[0029] Container 81, used for storing seeds;

[0030] The hopper body 82 is provided with a feed inlet 821 communicating with the hopper 81 and a discharge outlet 822;

[0031] A discharge mechanism 83 is disposed within the hopper 82 and is used to quantitatively transport seeds from the inlet 821 to the outlet 822. The discharge mechanism 83 includes a discharge shaft 831 connected to a power source, a discharge cylinder 832 disposed on the discharge shaft 831, and a quantitative hopper 833 recessed in the discharge cylinder 832. The discharge cylinder 832 is disposed close to the outlet 822 to separate the inlet 821 and the outlet 822.

[0032] When the metering bin 833 passes through the inlet 821, the seeds in the hopper 81 fall into the metering bin 833 and rotate with the metering bin 833 to the outlet 822 for discharge. Figure 1 As shown, to showcase the internal structure, parts of the bins and bins are rendered with perspective.

[0033] This utility model provides a seed storage device. In use, seeds are first placed in the storage hopper. After passing through the inlet, the seeds fall into the quantitative storage hopper. When the discharge shaft rotates, it drives the discharge cylinder to rotate, causing the quantitative storage hopper to rotate to the discharge outlet and be discharged. Since the seeds outside the quantitative storage hopper are blocked by the inlet, they cannot enter the discharge outlet. Only the seeds in the quantitative storage hopper can pass through, thereby achieving the effect of quantitative sowing.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a seed bin frame 86 disposed on the bin body and used for connection with a seeder.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes an adjustment mechanism 84 for adjusting the capacity of the quantitative container 833. This allows for adjustment of the seeding rate according to seeding requirements.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the adjusting mechanism 84 includes an adjusting wheel 841 disposed on the discharge shaft 831, an adjusting block 842 embedded in the metering bin 833, and an adjusting assembly disposed between the adjusting wheel 841 and the adjusting block 842. The adjusting wheel 841 drives the adjusting block 842 to move along the length of the metering bin 833 to reduce or increase the space occupied by the metering bin 833. Since the sowing amount is the amount of seeds stored in the metering bin, adjusting the size of the metering bin is equivalent to adjusting the storage amount.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the adjusting assembly includes a first rotating sleeve 843 sleeved on the discharge shaft 831 and rotating synchronously with the adjusting wheel 841, and a second rotating sleeve 844 threadedly engaged with the first rotating sleeve 843. The adjusting block 842 is disposed on the second rotating sleeve 844. When the adjusting wheel 841 rotates around the discharge shaft 831, the first rotating sleeve 843 rotates relative to the second rotating sleeve 844, thereby driving the adjusting block 842 to move along the axial direction of the discharge shaft 831, thereby adjusting the insertion depth into the metering chamber 833. The adjusting wheel drives the first rotating sleeve to rotate. At this time, since the power source is not started, the discharge shaft and discharge cylinder are stationary. The second rotating sleeve, under the threaded engagement, drives the adjusting block to move along the axial direction of the discharge cylinder.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, a plurality of the metering bins 833 are evenly spaced along the circumference of the discharge cylinder 832, and a plurality of adjusting blocks 842 are evenly spaced along the circumference of the second rotating sleeve 844, with each metering bin 833 corresponding to one adjusting block 842. After the power source is started, it drives the discharge shaft to rotate, thereby achieving uniformly spaced material discharge.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the adjusting block 842 is kept inserted into the metering chamber 833 so that the discharge cylinder 832 and the second rotating sleeve 844 rotate synchronously.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the adjusting mechanism 84 further includes a switching component. This switching component is used to cause the discharge cylinder 832 to rotate synchronously with the first rotating sleeve 843, so that all three rotate synchronously with the second rotating sleeve 844, maintaining the space occupied by the adjusting block 842; or it is used to cause the first rotating sleeve 843 and the second rotating sleeve 844 to rotate relative to each other, thereby adjusting the space occupied by the adjusting block 842. The switching component ensures that after the power source is started, the first and second rotating sleeves will not rotate relative to each other, that is, the adjusting block will not move, and the storage amount in the metering bin remains fixed.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the switching assembly includes a preload spring 845 with both ends pressing against the discharge cylinder 832 and the first rotating sleeve 843 respectively. When the discharge shaft 831 drives the discharge cylinder 832 to rotate, the first rotating sleeve 843 is pressed by the preload spring 845 so that the first rotating sleeve 843 rotates synchronously with the discharge cylinder 832. When the adjusting wheel 841 drives the first rotating sleeve 843 to rotate, the first rotating sleeve 843 overcomes the pressing force of the preload spring 845 and rotates relative to the second rotating sleeve 844.

[0042] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, it also includes an anti-crushing mechanism 85 for confining seeds outside the metering bin 833 at the feed inlet 821. This is to prevent seeds from being crushed in the gap between the feed inlet and the discharge cylinder during discharge, thus preventing damage to the seeds.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the anti-crushing mechanism 85 includes a brush head 851 disposed within the chamber 82, and bristles 852 disposed on the brush head 851. The bristles 852 abut against the outer wall of the discharge cylinder 832. When the metering chamber 833 passes through the bristles 852 and leaves the inlet 821, the bristles 852 trap the seeds outside the metering chamber 833 at the inlet 821. This avoids the gap between the inlet and the discharge cylinder being rigid, which could cause the seeds to be crushed.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the discharge cylinder is provided with a limiting ring 87 for preventing the first rotating sleeve from disengaging from the discharge cylinder.

[0045] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
