Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco planting supporting tool technology field, concretely relates to adjustable tobacco transplanting distance device of plant distance. BACKGROUND

[0002] Tobacco is mainly seedling transplanting crop, and transplanting is an important link of flue-cured tobacco planting. As an important work link of tobacco standardization production, flue-cured tobacco transplanting has strict requirements on transplanting specification quality. Transplanting specification directly affects planting density, and planting density significantly affects tobacco yield and quality. In the determination of plant distance of the traditional transplanting method, meter rule is usually used to distance, and then transplanting hole is punched. The error of the method for measuring plant distance using the traditional meter rule is large, which leads to great difference of transplanting density, and further seriously affects the yield and quality of flue-cured tobacco.

[0003] In order to solve the above problems, a tobacco single-wheel distance setter is disclosed in Chinese patent (publication number: CN206713375U), which punches holes on the ground film by setting four hole heads on the outer side of the steel ring when the steel ring rolls to complete distance setting, the included angle between adjacent hole heads is 90°, and the distance between holes is uniform.

[0004] But the distance between the two hole heads of the distance setter cannot be changed when it is used, and it cannot be suitable for distance setting work of different hole distances. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a tobacco transplanting distance device with adjustable plant distance, which solves the problem that the existing distance setter cannot be suitable for distance setting work of different hole distances.

[0006] The above technical purpose of the utility model is realized by the following technical scheme: a tobacco transplanting distance device with adjustable plant distance, comprising: a fixed shaft, a holding piece, a sleeve, a support piece and an elastic piece.

[0007] The fixed shaft is fixedly installed at one end of the holding piece.

[0008] The sleeve is rotationally connected with the fixed shaft, and a plurality of support pieces are fixedly connected with the sleeve outside in equal interval along the circumferential direction.

[0009] The length of the support piece is adjustable, and a distance setting column is connected with the end of the support piece away from the sleeve.

[0010] The elastic member is strip-shaped, has a first end and a second end, the first end of the elastic member is overlapped outside the second end, the elastic member is bent to form a wheel rim, a through hole is formed in the first end of the elastic member, a plurality of first sliding holes corresponding to the plurality of distance columns are formed in the elastic member, the first sliding holes are strip-shaped holes, one of the distance columns passes through the through hole and the first sliding hole, and the rest of the distance columns pass through the corresponding first sliding holes, the distance column is connected to a limiting member, and the elastic member is clamped in the middle by the limiting member and the supporting member.

[0011] The principle and effects of the above technical solution are as follows: in use, the wheel rim formed by the elastic member is rolled by the gripping member, and the distance is completed by the distance column connected with the adjustable supporting member punching holes in the ground film. Because the adjustable supporting members are equidistantly provided with a plurality of distance columns, the corresponding plurality of distance columns can punch holes in the ground film with uniform intervals. When the distance interval is increased, the length of all the adjustable supporting members is adjusted to be longer, so as to push the wheel rim formed by the elastic member away from the fixed shaft, thereby increasing the diameter of the wheel rim. During the process of increasing the diameter of the wheel rim, the distance column slides in the through hole, thereby facilitating the increase of the diameter of the wheel rim, and the elastic member is limited by the limiting member, thereby avoiding the elastic member from separating from the distance column. When the distance interval is reduced, the length of all the adjustable supporting members is adjusted to be shorter, so as to push the elastic member towards the fixed shaft by the limiting member, thereby reducing the diameter of the wheel rim formed by the elastic member, and further reducing the distance interval of the distance column, thereby achieving the effect of adjusting the distance interval, and thereby facilitating the adaptation to different distance requirements.

[0012] The utility model further sets up, the supporting member includes fixed connecting piece, movable connecting piece and lock bolt, one end of fixed connecting piece is connected with sleeve fixedly, strip-shaped second sliding hole is formed in fixed connecting piece, strip-shaped third sliding hole is formed in movable connecting piece, one end of movable connecting piece is connected with distance column fixedly away from fixed connecting piece, the thread section of lock bolt is arranged in second sliding hole and third sliding hole, and fixed connecting piece and movable connecting piece are fixed together through lock bolt.

[0013] By adopting the above technical scheme, the fixed connecting piece and the movable connecting piece are fixed together through the lock bolt, when it is necessary to adjust the length of the supporting member, the lock bolt is loosened, so that the fixed connecting piece and the movable connecting piece can slide relative to each other, and then the length of the supporting member is adjusted to a suitable length. When the length of the supporting member is adjusted to a suitable length, the lock bolt is tightened, so that the fixed connecting piece and the movable connecting piece are fixed together by the lock bolt, which is simple in structure and convenient to use.

[0014] The utility model further sets up, the distance column is a threaded column, the limiting member is a nut, and the limiting member is threadedly connected on the distance column.

[0015] By adopting the above technical solution, since the limiting member is threadedly connected to the spacer post, by adjusting the position of the limiting member on the spacer post, the limiting member and the corresponding support member can be adjusted to clamp the elastic member together, thereby enhancing the stability of the wheel rim formed by the elastic member; or the distance between the limiting member and the corresponding support member can be increased, thereby facilitating the spacer post to slide in the corresponding first sliding hole.

[0016] The present invention is further configured such that the end of the spacer column away from the sleeve is a pointed end.

[0017] By adopting the above technical solution, since one end of the spacing post is a pointed tip, it is easier for the spacing post to puncture the mulch film and insert into the soil, thus facilitating fixed-distance drilling.

[0018] The present invention is further configured such that the elastic element is a steel sheet with elasticity.

[0019] By adopting the above technical solution, since the elastic element is a flexible steel sheet, the wheel rim formed by the elastic element is lightweight and easy to carry. Attached Figure Description

Sleeve 3 is rotatably connected with fixed shaft 1, and a plurality of supports 4 are fixedly connected at equal intervals in the circumferential direction on the outside of sleeve 3. The number of supports 4 is preferably 4, and the included angle between adjacent supports 4 is 90 DEG, arranged in a cross shape. The length of support 4 is adjustable, and one end of support 4 away from sleeve 3 is connected with distance column 6. Elastic piece 5 is strip-shaped, and specifically, elastic piece 5 is a steel sheet with elasticity. Elastic piece 5 has a first end and a second end, the first end of elastic piece 5 is overlapped on the outside of the second end, elastic piece 5 is bent to form a rim, a through hole 7 is formed in the first end of elastic piece 5, and a first sliding hole 8 corresponding to the four distance columns 6 is formed in elastic piece 5, and the first sliding hole 8 is a strip-shaped hole. One of distance columns 6 passes through the through hole 7 and the first sliding hole 8, and the remaining distance columns 6 all pass through the corresponding first sliding holes 8, and the end of distance column 6 is located outside the rim formed by elastic piece 5. Distance column 6 is connected with limiting piece 9, and elastic piece 5 is clamped in the middle by limiting piece 9 and support 4. Support 4 includes fixed connecting piece 401, movable connecting piece 402 and locking bolt 403, one end of fixed connecting piece 401 is fixedly connected with sleeve 3, the included angle between adjacent fixed connecting pieces 401 is 90 DEG, arranged in a cross shape.

[0029] Working principle: in use, the wheel formed by the elastic member 5 is driven by the handle 2 to roll on the ground film surface, and the fixed distance column 6 connected with the adjustable support 4 punches holes on the ground film, thereby completing the fixed distance. Since the adjustable support 4 is provided with a plurality of equal intervals, a plurality of corresponding fixed distance columns 6 can punch holes on the ground film with uniform intervals. When the fixed distance interval is increased, the length of all adjustable supports 4 is adjusted to be longer, thereby pushing the wheel formed by the elastic member 5 away from the fixed shaft 1, so that the diameter of the wheel is increased.

When the fixed distance interval is reduced, the length of all adjustable supports 4 is adjusted to be shorter, thereby pushing the elastic member 5 towards the fixed shaft 1 by the limiting member 9, so that the diameter of the wheel formed by the elastic member 5 is reduced, thereby reducing the fixed distance interval of the fixed distance column 6, achieving the effect of adjusting the fixed distance interval, thereby facilitating the adaptation to different fixed distance requirements. The fixed connecting member 401 and the movable connecting member 402 are fixed together by the locking bolt 403, when it is necessary to adjust the length of the support 4, the locking bolt 403 is loosened, so that the fixed connecting member 401 and the movable connecting member 402 can slide relative to each other, thereby adjusting the support 4 to a suitable length. When the support 4 is adjusted to a suitable length, the locking bolt 403 is tightened, so that the locking bolt 403 fixes the fixed connecting member 401 and the movable connecting member 402 together, which is simple in structure and convenient to use. Since the limiting member 9 is threadedly connected to the fixed distance column 6, by adjusting the position of the limiting member 9 on the fixed distance column 6, the limiting member 9 can be adjusted to be clamped together with the corresponding support 4 to enhance the stability of the wheel formed by the elastic member 5, or the interval distance between the limiting member 9 and the corresponding support 4 is adjusted to facilitate the sliding of the fixed distance column 6 in the corresponding first sliding hole 8. Since one end of the fixed distance column 6 is a sharp end, the fixed distance column 6 is easier to pierce the ground film and insert into the soil, thereby facilitating the fixed distance punching. The overall structure is simple and easy to carry.
