This is to solve the problem that the marking intervals made by the punching nails on the ground film in the prior art are fixed and cannot be adjusted, which makes the use scenario of the marker with fixed marking spacing narrow."

[0003] However, although the mulch markers in the prior art have achieved the adjustability of the punching spacing, there are still some deficiencies: the existing mulch markers realize the installation of punching nails through the installation holes pre-drilled on the spoke wheel, which makes it impossible for the punching nails to achieve linear adjustment in the circumferential direction of the spoke wheel, which leads to a small range of adjustable punching spacing and a deviation in universality; secondly, two wedge blocks are required to fix the position of the spoke wheel, which requires the bolts to be disassembled and assembled twice, reducing the adjustment efficiency, and there is rotational friction between the wedge block and the wheel hub, which causes the wedge block to wear over a long period of time, which in turn causes the wheel hub to rotate and produce ore. Utility Model Content

[0004] In order to overcome the defects of the prior art, a universal agricultural mulch marker is provided to solve the problems that the existing agricultural mulch markers cannot achieve linear adjustment of the hole spacing, resulting in universal deviation, and the adjustment process of the spoke wheel spacing is cumbersome, affecting agricultural efficiency.

[0005] To achieve the above-mentioned purpose, a universal agricultural mulch marker is provided, comprising: a groove wheel, a telescopic shaft, a handle and a center rod, the edge of the groove wheel is slidably connected with a punching piece, and the punching piece includes an adjusting block, and a threaded column is screwed inside the adjusting block, and a punching nail is connected to the outer end of the threaded column, a hub is provided at the center of the groove wheel, and a positioning sleeve is rotatably connected to the inner side of the hub, and the positioning sleeve is slidably sleeved on the surface of the telescopic shaft, the telescopic shaft is slidably sleeved on both ends of the center rod, and the handle is rotatably connected to the middle part of the center rod, and the telescopic shaft is rotatably inserted in the hub.

DETAILED DESCRIPTION

[0020] Reference Figures 1 to 4 As shown, the utility model provides a universal agricultural mulch film marker, comprising: a groove wheel 1, a telescopic shaft 2, a handle 3 and a center rod 4.

[0021] Specifically, a punching piece 11 is slidably connected to the edge of the groove wheel 1, and the punching piece 11 includes an adjusting block 111, and a threaded column 113 is screwed inside the adjusting block 111, and a punching nail 114 is connected to the outer end of the threaded column 113. A hub 14 is provided at the center of the groove wheel 1, and a positioning sleeve 15 is rotatably connected to the inner side of the hub 14, and the positioning sleeve 15 is slidably sleeved on the surface of the telescopic shaft 2, the telescopic shaft 2 is slidably sleeved on both ends of the center rod 4, and the handle 3 is rotatably connected to the middle part of the center rod 4, and the telescopic shaft 2 is rotatably inserted into the hub 14.

[0022] In this embodiment, the groove wheel 1, the telescopic shaft 2, the handle 3 and the center rod 4 constitute the main structure of the universal agricultural mulch marker involved in this application, which is used to mark the drilling positions after laying the mulch film of crops and before drilling the mulch film holes.

[0023] Among them, the edge of the groove wheel 1 is provided with a groove, which is the wheel groove described below.

[0024] It should be noted that the punching member 11 is actually a punching marking structure, and the punched small holes cannot be used as planting holes but are only used as marking holes.

[0025] Specifically, the sheave 1 includes spokes 13 connected to the hub 14 on the inner side, and an angle plate 12 is provided on the outer side of the sheave 1. Annular grooves 16 are provided on the inner walls of the sheave grooves on both sides of the sheave 1, and sliders 115 are fixed on both sides of the adjustment block 111, and the sliders 115 are slidably connected in the annular grooves 16.

[0026] In the present embodiment, the hub 14 and the spokes 13 on the inner side of the sheave 1 are common structures of the sheave 1 .

[0027] It should be noted that the angle disc 12 is actually a circumferential scale engraved on the outer circumferential direction of the groove wheel 1, so that the protruding punching nails 114 can be used as a reference for adjusting the spacing in the circumferential direction.

[0028] Specifically, the bottom of the adjusting block 111 is set to an arc structure, and the adjusting block 111 is slidably connected in the wheel groove of the groove wheel 1. At the same time, a locking bolt is threaded through the inside of the adjusting block 111, and a receiving groove 112 with a thread is opened inside the adjusting block 111, and the threaded column 113 is threaded in the receiving groove 112, and when the threaded column 113 is rotated to the bottom of the receiving groove 112, the outer end of the punching nail 114 does not exceed the edge of the groove wheel 1.

[0029] In this embodiment, the punching nail 114 is configured as a cone structure with the tip facing outwards, and anti-slip grooves are provided on the surface of the cone, so that the punching nail 114 can be manually rotated to drive the threaded column 113 to rotate, thereby achieving the telescopic effect of the punching nail 114.

[0030] Specifically, an annular groove 141 is formed on the end face of the wheel hub 14 facing the positioning sleeve 15, and a shaft sleeve 153 is connected to the opposite side of the positioning sleeve 15. At the same time, a retaining ring 154 is connected to the outer end of the shaft sleeve 153, and the retaining ring 154 is rotatably connected in the groove 141. An axial shaft hole 152 is formed in the middle of the positioning sleeve 15, and a positioning bolt 151 extending into the shaft hole 152 is threaded on the outer side of the positioning sleeve 15. At the same time, the telescopic shaft 2 is inserted into the positioning sleeve 15 and the shaft sleeve 153.

[0031] It should be noted that a positioning hole is formed on the outer wall of the telescopic shaft 2 , and the positioning bolt 151 passes through the positioning sleeve 15 and is connected to the positioning hole correspondingly.

[0032] As a preferred embodiment, by setting the card slot 141 and the card ring 154 to connect, the positioning sleeve 15 can be driven to move when the sheave 1 is moved axially, and when the positioning sleeve 15 is fixed to the telescopic shaft 2, the hub 14 can rotate freely.

[0033] When in use, first adjust the spacing of the groove wheels according to the width of the crop ridges. Specifically, the telescopic shaft is expanded or contracted and slid relative to the center rod, and then the telescopic shaft is fixed, and then the positioning sleeve is expanded or contracted and slid relative to the telescopic shaft, and then fixed by the positioning bolt, thereby realizing the spacing adjustment of the groove wheels on both sides. At the same time, for larger crop ridge widths, two-level expansion adjustment can be achieved through the telescopic shaft and the positioning sleeve, which is more flexible and convenient to use. When adjusting the punching spacing, first loosen the locking bolt on the adjustment block, and then rotate the adjustment block along the circumferential direction of the groove wheel, and make the angles of adjacent adjustment blocks equal through the angle disk, and then rotate the punching nails to protrude from the outer edge of the groove wheel through the threaded column, thereby realizing linear stepless adjustment, increasing the range of punching spacing adjustment, and improving the versatility of the device.

[0034] The universal agricultural mulch marker of the utility model can effectively solve the problems of existing agricultural mulch markers that cannot realize linear adjustment of the hole spacing, resulting in universal deviation, and the adjustment process of the spoke wheel spacing is cumbersome, which affects the farming efficiency. It is realized on the basis of the existing universal agricultural mulch marker technology, so that the marker can realize the adjustment of the linear hole spacing, increases the universality of the planting spacing of different crops, and facilitates the adjustment of the groove wheel spacing, thereby improving the farming efficiency.
