[0041] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Example 1

[0043] like Figures 1 to 7 As shown, this embodiment provides a peanut single-grain precision sowing and metering device, including a peanut seed storage mechanism, a peanut seed releasing mechanism, a plant spacing measuring mechanism and a movable frame 1, wherein the peanut seed storage mechanism is fixedly mounted on the frame 1 and is used to store a variety of different peanut seeds; the peanut seed releasing mechanism is mounted on the frame 1 and is used to sow the various different peanut seeds in the peanut seed storage mechanism into cultivated land; the plant spacing measuring mechanism is mounted on the frame 1.

[0044] During the sowing process, the entire device moves on the cultivated land, uses the peanut seed storage mechanism to store a variety of different peanut seeds, and uses the peanut seed release mechanism to sow the peanuts one by one in the cultivated land, realizing the single-grain precision sowing of peanuts;

[0045] During this process, the distance between two adjacent peanut plants is measured using a plant spacing measurement mechanism to ensure precise sowing of peanuts.

[0046] Preferably, in this embodiment, two pairs of wheels 13 are installed on both sides of the frame 1 for relative rotation, and the two pairs of wheels 13 are respectively distributed at the front and rear ends of the frame 1, which is reasonably designed and convenient for moving the entire device.

[0047] This embodiment has a simple structure and a reasonable design, and can realize single-grain precision sowing of peanuts without the need to manually place peanut seeds one by one. The sowing is convenient, efficient, and has low labor intensity.

[0048] Example 2

[0049] On the basis of Example 1, in this embodiment, the peanut seed storage mechanism includes a storage box 2 with an open upper end, and the internal space of the storage box 2 is divided into a plurality of storage cavities 3 by a plurality of vertically arranged partitions, and the plurality of partitions are evenly spaced and distributed from one side of the storage box 2 to the other side; the bottoms of the plurality of storage cavities 3 are respectively provided with sowing openings 4 that penetrate inside and outside, and each of the sowing openings 4 only allows a single peanut to pass through; the peanut seed release mechanism is located at the plurality of sowing openings 4.

[0050] The solution has a simple structure and a reasonable design. The space in the storage box 2 is divided into a plurality of storage chambers 3 by a partition plate so as to store different peanut seeds and facilitate sowing.

[0051] Based on the above solution, a plurality of partitions are respectively formed integrally with the storage box 2 .

[0052] In addition, the size of the multiple sowing openings 4 is slightly larger than the size of a single peanut, ensuring that the peanuts in each storage cavity 3 pass through the sowing opening 4 one by one.

[0053] Based on the above scheme, due to sowing requirements, the above multiple sowing ports 4 are not evenly spaced. For four sowing ports 4, the spacing between the first sowing port 4 and the second sowing port 4 from left to right is equal to the spacing between the third sowing port 4 and the fourth sowing port 4, but the spacing between the first sowing port 4 and the second sowing port 4 is smaller than the spacing between the second sowing port 4 and the third sowing port 4. This scheme is only applicable to cultivated land with a certain row spacing.

[0054] Example 3

[0055] On the basis of Embodiment 2, in this embodiment, the plurality of storage cavities 3 are respectively in a conical structure.

[0056] The solution has a simple structure, and the shapes of the multiple storage chambers 3 are reasonably designed, ensuring that individual peanuts fall into the sowing opening 4 one by one, thereby achieving single peanut sowing.

[0057] Example 4

[0058] On the basis of Example 1, in this embodiment, the peanut seed storage mechanism includes a plurality of storage boxes 2 with open upper ends, and the plurality of storage boxes 2 are spaced apart from each other in the direction from one side of the frame 1 to the other side, and the bottoms thereof are respectively provided with sowing openings 4 penetrating inside and outside, and each of the sowing openings 4 only allows a single peanut to pass through; the peanut seed release mechanism is located at the plurality of sowing openings 4.

[0059] The solution has a simple structure and a reasonable design. A plurality of storage boxes 2 are used to store different peanut seeds, which makes sowing convenient.

[0060] Based on the above scheme, based on the above scheme, due to sowing requirements, the above-mentioned multiple sowing ports 4, i.e., the four storage boxes 2, are not evenly spaced. With four sowing ports 4, the distance between the first sowing port 4 and the second sowing port 4 from left to right is equal to the distance between the third sowing port 4 and the fourth sowing port 4, but the distance between the first sowing port 4 and the second sowing port 4 is smaller than the distance between the second sowing port 4 and the third sowing port 4.

[0061] In addition, in order to meet the needs of different row spacings in different cultivated fields, multiple storage boxes 2 are preferably detachably mounted on the frame 1 by bolts, and the storage boxes 2 can be installed at different locations on the frame 1 according to needs, which is more versatile.

[0062] The above-mentioned Embodiment 2 and Embodiment 4 are parallel solutions, and the difference between the two is that the storage box 2 in Embodiment 2 adopts an integrated structure, and its internal space is divided into multiple storage chambers 3 by multiple partitions; while Embodiment 4 adopts multiple independent storage boxes 2.

[0063] Example 5

[0064] On the basis of Embodiment 4, in this embodiment, the plurality of storage boxes 2 are respectively in a conical structure.

[0065] The solution has a simple structure, and the shapes of the multiple storage boxes 2 are reasonably designed, ensuring that individual peanuts fall into the sowing opening 4 one by one, thereby achieving single peanut sowing.

[0066] Example 6

[0067] On the basis of Example 2 or Example 4, in this embodiment, the peanut seed release mechanism includes a rotating shaft 5 and a plurality of rotating balls 6, and the plurality of rotating balls 6 are respectively installed at the plurality of sowing ports 4, and are respectively provided with sowing grooves 7; the rotating shaft 5 is horizontally installed on the frame 1, and respectively passes through the centers of the plurality of rotating balls 6, and the rotating shaft 5 can rotate horizontally to drive the plurality of rotating balls 6 to rotate until the plurality of sowing grooves 7 thereon are respectively connected with the plurality of sowing ports 4.

[0068] During the sowing process, when the equipment moves to the set positions where the multiple sowing ports 4 are located on the cultivated land, the above-mentioned rotating shaft 5 can be manually rotated, and the rotating shaft 5 drives the multiple rotating balls 6 to rotate to the multiple sowing grooves 7 to be connected with the multiple sowing ports 4 respectively. At this time, multiple peanuts fall into the multiple sowing grooves 7 respectively; continue to rotate the rotating shaft 5 until the multiple sowing ports 4 are vertically downward respectively, so that the peanuts in the multiple sowing ports 4 fall to the set positions of the cultivated land respectively, thereby realizing the sowing of peanuts.

[0069] Based on the above scheme, the inner walls of the multiple sowing ports 4 are preferably arc-shaped structures, and the multiple rotating balls 6 partially extend into the multiple sowing ports 4 and rotatably fit with the inner walls of the multiple sowing ports 4 respectively.

[0070] In addition, multiple rotating balls 6 are movably mounted on the rotating shaft 5, and the multiple rotating balls 6 are respectively provided with through holes for the rotating shaft 5 to pass through; at the same time, the multiple rotating balls 6 are respectively provided with screw holes connected to the through holes on themselves, and locking screws are respectively threadedly installed in the multiple screw holes, and the multiple locking screws are used to fix the multiple rotating balls 6 on the rotating shaft 5.

[0071] On the basis of Embodiment 4, the positions of the plurality of rotating balls 6 can be adaptively adjusted according to the positions of the plurality of storage boxes 2 .

[0072] It should be noted that the nut ends of the locking screws on the multiple rotating balls 6 are located in grooves on the multiple rotating balls 6 that are coaxially distributed with the multiple through holes, so the multiple locking screws will not affect the rotation of the multiple rotating balls 6.

[0073] Example 7

[0074] On the basis of Example 6, in this embodiment, one end of the rotating shaft 5 is fixedly connected to a handle 8 .

[0075] The solution has a simple structure and a reasonable design. The sowing personnel use the handle 8 to rotate the rotating shaft 5, which is easy to operate and saves time and effort.

[0076] Preferably, in this embodiment, the handle 8 can be a straight rod structure, in which case it is perpendicular to the rotation shaft 5 and one end of the handle 8 is fixedly connected to one end of the rotation shaft 5 .

[0077] Alternatively, the handle 8 may also be a Z-shaped rod structure, in which case one end of the handle 8 is fixedly connected to one end of the rotating shaft 5 .

[0078] Example 8

[0079] On the basis of any one of Examples 6 to 7, in this embodiment, a plurality of guide cylinders 9 with thick upper ends and thin lower ends are vertically fixedly mounted on the frame 1, and the plurality of guide cylinders 9 are evenly spaced from one side of the frame 1 to the other side, and are respectively located below the plurality of rotating balls 6.

[0080] This solution has a simple structure and a reasonable design. The guide cylinder 9 can be used to guide multiple peanuts to the set position of the cultivated land with higher accuracy.

[0081] Preferably, in this embodiment, the size of the upper ends of the multiple guide cylinders 9 is larger than the diameter of the multiple rotating balls 6, ensuring that the peanuts in the multiple sowing grooves 7 can be smoothly transferred into the multiple guide cylinders 9 as the multiple rotating balls 6 rotate with the rotating shaft 5, thereby ensuring the accuracy of sowing.

[0082] Example 9

[0083] On the basis of the above embodiments, in this embodiment, the plant spacing measurement mechanism includes a measuring ruler 10, and the measuring ruler 10 is horizontally installed on the frame 1 along the front-to-back direction, and can be moved back and forth and positioned.

[0084] Before sowing, the measuring ruler 10 is manually moved to a set position and positioned according to the required plant spacing to ensure consistency of the plant spacing.

[0085] Preferably, in this embodiment, the measuring ruler 10 is preferably a long strip plate structure.

[0086] Preferably, in this embodiment, a slide groove with a closed front end and an open rear end is provided on one side of the frame 1 along the front-to-back direction, and the measuring ruler 10 is installed in the slide groove for horizontal sliding front and back, and its rear end extends outside the rear end of the slide groove.

[0087] In addition, a screw hole is provided on the upper side of the open end of the slideway, and a locking screw is connected to the inner thread of the screw hole. When in use, the measuring ruler 10 is manually moved to a set position, and then the locking screw is manually turned until one end thereof abuts against the measuring ruler 10 to fix the measuring ruler 10.

[0088] When in use, the distance between the rear end of the measuring ruler 10 and the rear end of the frame 1 is the spacing between the peanuts planted.

[0089] Example 10

[0090] Based on Example 9, this embodiment also includes a mounting rod 11 and multiple pairs of soil covering plates 12, wherein the mounting rod 11 is horizontally arranged, and one end thereof is fixedly connected to the rear end of the measuring ruler 10; multiple pairs of the soil covering plates 12 are fixedly installed on the mounting rod 11 at uniform intervals along the length direction of the mounting rod 11, and correspond one-to-one to the multiple sowing ports 4.

[0091] During the sowing process, multiple pairs of soil covering plates 12 are used to cover the soil in the grooves for sowing peanuts, thereby completing the sowing of peanuts.

[0092] Preferably, in this embodiment, each pair of soil covering plates 12 are respectively distributed in a V-shape to facilitate soil covering operations.

[0093] It should be noted that when the entire equipment is moving, the two pairs of wheels 13 respectively cross the two long sides of the rectangular cultivated land where peanuts are planted, so the horizontal height of the multiple pairs of soil covering plates 12 is higher than the horizontal height of the two pairs of wheels 13.

[0094] Based on the above scheme, when the measuring ruler 10 is stored in the slide slot, the mounting rod 11 is close to the rear end of the frame 1. When the measuring ruler 10 partially extends out of the slide slot, the mounting rod 11 and multiple pairs of covering plates 12 move with the measuring ruler 10 respectively.

[0095] In addition, the furrows for sowing peanuts on the cultivated land are cleared in advance using other tools.

[0096] The working principle of the present invention is as follows:

[0097] The measuring ruler 10 is manually moved out of the chute to a set length in advance, and a plurality of peanut seeds to be sown are placed in a plurality of storage chambers 3 or a plurality of storage boxes 2;

[0098] The whole device is manually pushed to move on the cultivated land. When the multiple guide cylinders 9 are moved to the set position, the handle 8 is used to manually rotate the rotating shaft 5, and the rotating shaft 5 drives the multiple rotating balls 6 to rotate to the multiple sowing grooves 7 and respectively connect with the multiple sowing ports 4. At this time, multiple peanuts fall into the multiple sowing grooves 7 respectively; the rotating shaft 5 is further rotated until the multiple sowing ports 4 are vertically downward respectively, so that the peanuts in the multiple sowing ports 4 fall to the set position of the cultivated land respectively through the multiple guide cylinders 9, so as to realize the sowing of a row of peanuts;

[0099] Continue to move the device to the next position, at which time the rear end of the measuring ruler 10 is just flush with the peanuts planted in the previous row, and repeat the above operation to complete the planting of the next row of peanuts.
