Description

Technical Field

[0001] The utility model relates to the technical field of tomato planting, in particular to a weeding device for tomato planting. Background Art

[0002] Tomato planting refers to the process of growing tomato plants, from sowing to harvesting ripe tomatoes. This process includes selecting suitable varieties, preparing soil, sowing or transplanting seedlings, providing appropriate light, water and temperature, fertilizing, managing pests and diseases, etc. Tomato planting can be done indoors or outdoors, and can be adjusted and managed as needed to promote plant growth and yield. When tomatoes are planted, weeds will grow in the planting area, and the weeds will absorb nutrients from the soil, so they need to be weeded frequently.

[0003] For example, a weeding device disclosed in the authorization announcement number CN214545364U includes a base, a rod body and a handle connected in sequence, the base is equipped with a grass grabbing component that can be opened / closed, the handle is equipped with an operating component, and the grass grabbing component is connected to the operating component through a connecting piece. After adopting the above technical solution, the beneficial effects of the utility model are as follows: by designing a weeding device that simulates human fingers, the weed roots can be grasped in a standing position to pull up the weeds by the roots, which is particularly suitable for weeding in konjac fields and crop fields with high planting density.

[0004] Although the above patent can grab the grass roots in a standing position and pull out the weeds by the roots, which is particularly suitable for weeding in konjac fields and crop fields with high planting density, the above weeding device cannot be adapted and adjusted according to the depth of the weed roots in the soil. Therefore, two different types of devices need to be carried at the same time when weeding, and they need to be frequently replaced during use. Such a weeding device is too cumbersome to use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0023] A weeding device for tomato planting, comprising a first jacket 1 and a second jacket 2, the top ends of the first jacket 1 and the second jacket 2 are both fixedly connected with a connecting arm 3, the bottom ends of the two connecting arms 3 are movably connected through a rotating shaft, the outer sides of the two connecting arms 3 are both provided with a transmission mechanism, the transmission mechanism comprises a shaft sleeve 6, a transmission shaft 7 and a handle 8, the shaft sleeve 6 is symmetrically arranged on the outer sides of the top and bottom ends of the connecting arm 3, the transmission shaft 7 is movably installed inside the two shaft sleeves 6, the top end of the transmission shaft 7 is fixedly connected to the handle 8, and the outer side of the handle 8 is provided with a rubber anti-slip sleeve;

[0024] In this embodiment, when weeds with shallow roots on the tomato planting ground are cleared, the first jacket 1 and the second jacket 2 are respectively put on the upper end of the weeds, and then the two connecting arms 3 are crossed and merged. After the two connecting arms 3 are crossed and merged, the first jacket 1 and the second jacket 2 are controlled to clamp the weeds, and then the connecting arms 3 or the handle 8 are lifted to clear the shallow weeds. In this way, the weeds with shallow roots on the tomato planting ground can be conveniently cleared.

[0025] like Figure 4 As shown, a movable groove 4 is provided at the lower middle part of the first clamping sleeve 1 and the second clamping sleeve 2, and a clamping plate 5 is movably installed inside the two movable grooves 4. A lifting mechanism is provided between the clamping plate 5 and the connecting arm 3, and the lifting mechanism includes a fixed seat 9 and a threaded sleeve 10. The fixed seat 9 is fixedly connected to one side of the middle part of the top end of the clamping plate 5, and the threaded sleeve 10 is fixedly installed at the top end of the clamping plate 5. The bottom end of the transmission shaft 7 is provided with a threaded groove threadedly connected to the threaded sleeve 10.

[0026] In this embodiment, when cleaning weeds with deeper roots on the tomato planting ground, the two handles 8 are rotated respectively, and the handles 8 control the rotation of the transmission shaft 7. When the transmission shaft 7 rotates, the threaded sleeve 10 is driven to descend linearly. When the threaded sleeve 10 descends, the clamping plate 5 is pushed down from the movable groove 4, and then the two clamping plates 5 are inserted into the soil. Then, the two handles 8 are held with both hands and rotated, and a circular groove is dug in the soil outside the weeds through the clamping plates 5. Then, the weeds are clamped by the two clamping plates 5 and pulled out to the outside, so that the weeds with deeper roots on the tomato planting ground can be effectively cleaned.

[0027] like Figure 3 As shown, the inner surfaces of the two clamping plates 5 are provided with a plurality of clamping teeth 11 at equal distances from top to bottom, and the clamping teeth 11 are arc-shaped structures;

[0028] In this embodiment, a plurality of clamping teeth 11 are provided on the inner wall surface of the clamping plate 5, so that when clamping weeds, the clamping degree can be improved to avoid slipping.

[0029] Working principle: when cleaning weeds with shallow roots on the tomato planting ground, the first clamp 1 and the second clamp 2 are respectively put on the upper end of the weeds, and then the two connecting arms 3 are crossed and merged. After the two connecting arms 3 are crossed and merged, the first clamp 1 and the second clamp 2 are controlled to clamp the weeds, and then the connecting arms 3 or the handles 8 are lifted to clean the shallow weeds; when cleaning weeds with deeper roots on the tomato planting ground, the two handles 8 are respectively rotated, and the handles 8 control the transmission shaft 7 to rotate. When the transmission shaft 7 rotates, the threaded sleeve 10 is driven to drop linearly. When the threaded sleeve 10 drops, the clamp 5 is pushed down from the movable groove 4, and then the two clamps 5 are inserted into the soil, and then the two handles 8 are held with both hands and rotated, and a circular groove is dug in the soil outside the weeds through the clamp 5, and then the weeds are clamped and pulled out to the outside through the two clamps 5, so that the weeds with deeper roots on the tomato planting ground can be effectively cleaned.
