Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural production equipment, and particularly relates to a crop plant spacing marking adjustable device. BACKGROUND

[0002] In agricultural production, the planting density of crops, i.e. the control of plant spacing, is one of the key factors that directly affect crop growth, yield and quality. In particular, in crop experimental research, accurate plant spacing not only helps scientists accurately assess the influence of factors such as different varieties, different fertilizer amounts and different irrigation strategies on crop growth, but also provides scientific guidance for agricultural practice, optimizes planting patterns and improves agricultural production efficiency.

[0003] However, in current agricultural production, especially in small-scale farmland experiments or traditional agricultural areas, the control of plant spacing still highly depends on manual operation. When manually transplanting seedlings, workers have great difficulty in accurately judging and maintaining consistent hole spacing by relying only on the naked eye and experience. Even experienced farmers cannot guarantee that the hole spacing is completely consistent every time, which leads to large differences in crop growth environment, affecting the consistency of crop growth and yield. Manual transplanting is slow, and especially in large-scale farmland or experiments that require frequent adjustment of plant spacing, manual operation not only consumes time and effort, but also easily leads to increased errors due to fatigue.

[0030] As shown in Figure 1 - Figure 5 Specifically, two supporting plates 15 are fixedly installed on the side of the first frame body 1 close to the rope roll 12, the two supporting plates 15 are symmetrically arranged on the two sides of the rope roll 12, the rope roll 12 is movably connected to the supporting plate 15 through a bearing on the two sides of the rope roll 12, a hand wheel 16 is movably installed on the side of the supporting plate 15 away from the rope roll 12, the hand wheel 16 is in transmission connection with the shaft of the rope roll 12, a plurality of support columns 17 are fixedly installed at the top end of the second frame body 11, the support columns 17 are correspondingly arranged with the rope rolls 12, a hanging ring 18 is fixedly installed at the top end of the support column 17, a plurality of fixed clamps 19 are movably connected to the outside of the positioning rope 13, and a positioning cone 110 is connected to one side of the fixed clamp 19 through a chain.

[0031] As can be seen from the above, the rope roll 12 can be rotated to wind or unwind the positioning rope 13, the scale outside the positioning rope 13 can be used to quickly determine the plant spacing, the hand wheel 16 can drive the rope roll 12 to rotate, the hanging ring 18 cooperates with the hook 14 to straighten the positioning rope 13, and the fixed clamp 19 and the positioning cone 110 are used to position the plant spacing into the soil.

[0032] In use, first, the first frame body 1 and the second frame body 11 are respectively placed on the two sides of the farmland, then the positioning rope 13 is pulled close to the support column 17, the rope roll 12 is automatically unwound, the hook 14 is hung on the hanging ring 18, then the scale value on the positioning rope 13 is found according to the experimental or production requirements, the fixed clamp 19 is clamped on the outside of the positioning rope 13, and then the positioning cone 110 is inserted into the corresponding soil, and at this time, the spacing of the positioning cone 110 is equal to the required plant spacing, and the worker can quickly transplant according to the position of the positioning cone 110, which is high in efficiency and accurate in position.
