Description

Technical Field

[0001] The utility model relates to the technical field of thinning seedlings, in particular to a millet thinning seedling device. Background Technique

[0002] Thinning seedlings, also known as thinning out seedlings, for protected ground sowing and open ground sowing, the seeding rate far exceeds the number of seedlings to be retained, resulting in crowded seedlings. To ensure that the seedlings have sufficient growth space and nutrient area, a part of the seedlings should be removed in a timely manner, and strong seedlings should be selected. This can make the air circulate among the seedlings, ensure sufficient sunlight, and timely thinning and final thinning can avoid crowded seedlings, mutual shading, save soil moisture and nutrients, and is conducive to cultivating strong seedlings.

[0003] Currently, when thinning millet seedlings, a millet thinning seedling device is usually used for operation. However, when the existing millet thinning seedling devices on the market are operating, only single millet seedlings can be removed each time, so the efficiency is low during thinning seedlings, and the labor intensity is relatively large. Content of the Utility Model

[0004] The purpose of the utility model is to provide a millet thinning seedling device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A millet thinning seedling device includes a bottom frame. A transmission shell is fixedly installed in the middle of the bottom frame. A sleeve is fixedly connected to the top end of the transmission shell. A number of pairwise symmetric clamping sleeves are arranged side by side at the bottom end of the bottom frame; A transmission rod is movably sleeved inside the sleeve. A handle is fixedly connected to the top end of the transmission rod. A transmission mechanism is arranged at one end of the output shaft of the transmission rod inside the transmission shell.

[0007] Preferably, the transmission mechanism includes a gear, a rack and a movable strip. The gear is fixedly connected to one end of the transmission rod inside the transmission shell. Racks are meshed at both ends of the transmission shell close to the gear. Movable strips are fixedly connected to both ends of the two racks;

[0008] Preferably, the transmission mechanism further includes a connecting piece. The connecting pieces are arranged at equal intervals on the lower surface of the bottom end of the movable strip. The bottom end of the connecting piece is fixedly connected to the clamping sleeve;

[0009] Preferably, a number of clamping teeth are sequentially arranged on the inner wall of the clamping sleeve from top to bottom;

[0010] Preferably, fixing blocks are symmetrically arranged at the top ends of both sides of the bottom frame. Through grooves are symmetrically arranged at both ends of the fixing block. Both ends of the movable strip are movably connected to the through grooves;

[0011] Preferably, guide grooves are opened on both sides in the middle of the bottom frame. The connecting piece is slidably connected to the guide groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For the millet thinning tool, through the cooperation of gears, racks, movable bars, connecting pieces and clamping teeth, when pulling out, several symmetrical clamping sleeves are sleeved from the upper end of the millet seedlings, and then the handle is held and rotated. The handle drives the gear inside the transmission shell to rotate through the transmission rod. The gear drives the racks at both ends to move horizontally. When the racks move, the symmetrical clamping sleeves are driven by the movable bar and the connecting piece to clamp the millet seedlings. Then, by lifting the handle, several millet seedlings in the same row can be pulled out at one time, thereby improving the thinning efficiency.

[0014] 2. For the millet thinning tool, clamping teeth are arranged on the inner walls of the clamping sleeves of the device. When two symmetrical clamping sleeves move in the same direction, the symmetrical clamping teeth on the inner walls of the two clamping sleeves will clamp at the strut of the millet seedlings. In this way, when the device is lifted, the clamping teeth will lift the seedlings and pull them out of the soil, so that slipping between the seedlings and the clamping sleeves can be avoided when pulling out.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-4 shown, a technical solution provided by the present utility model:

[0022] A millet thinning device includes a chassis 1. A transmission housing 2 is fixedly installed in the middle of the chassis 1. A sleeve 3 is fixedly connected to the top end of the transmission housing 2. A number of pairwise symmetric clamping sleeves 4 are arranged side by side at the bottom end of the chassis 1. A transmission rod 5 is movably sleeved inside the sleeve 3. A handle 6 is fixedly connected to the top end of the transmission rod 5. A transmission mechanism is arranged at one end of the output shaft of the transmission rod 5 inside the transmission housing 2. The transmission mechanism includes a gear 7, a rack 8 and a movable strip 9. The gear 7 is fixedly connected to one end of the transmission rod 5 inside the transmission housing 2. Racks 8 are meshed at both ends of the transmission housing 2 close to the gear 7. Movable strips 9 are fixedly connected to both ends of the two racks 8. The transmission mechanism further includes a connecting piece 10. The connecting pieces 10 are arranged at equal intervals on the lower surface of the bottom end of the movable strip 9. The bottom end of the connecting piece 10 is fixedly connected to the clamping sleeve 4.

[0023] In this embodiment, when using this device to thin millet seedlings, several millet seedlings in the same row can be removed simultaneously. When removing, several symmetric clamping sleeves 4 are sleeved from the upper end of the millet seedlings, and then the handle 6 is held and rotated. The handle 6 drives the gear 7 inside the transmission housing 2 to rotate through the transmission rod 5. The gear 7 drives the racks 8 at both ends to move horizontally. When the racks 8 move, the symmetric clamping sleeves 4 are driven to clamp the millet seedlings through the movable strips 9 and the connecting pieces 10. Then, by lifting the handle 6, several millet seedlings in the same row can be removed at one time, thereby improving the thinning efficiency.

[0024] As Figure 3 shown, several clamping teeth 11 are sequentially arranged on the inner wall of the clamping sleeve 4 from top to bottom;

[0025] In this embodiment, clamping teeth 11 are arranged on the inner walls of the clamping sleeves 4 of this device. When the two symmetric clamping sleeves 4 move in the same direction, the symmetric clamping teeth 11 on the inner walls of the two clamping sleeves 4 will clamp at the strut of the millet seedling. In this way, when lifting this device, the clamping teeth 11 will lift the seedling and lift it out of the soil, so that slipping between the seedling and the clamping sleeve 4 can be avoided when removing.

[0026] As Figure 2 shown, fixing blocks 12 are symmetrically arranged at the top ends on both sides of the chassis 1. Through grooves 13 are symmetrically arranged at both ends of the fixing blocks 12. Both ends of the movable strip 9 are movably connected to the through grooves 13. Guide grooves 14 are opened on both sides in the middle of the chassis 1. The connecting piece 10 is slidably connected to the guide grooves 14;

[0027] In this embodiment, when the movable strip 9 moves horizontally, its two ends slide and are guided in the through grooves 13 at both ends of the fixing block 12, and the connecting piece 10 will slide and be guided inside the guide groove 14.

[0028] Working principle: When using this device to thin out millet seedlings, several millet seedlings in the same row can be pulled out at the same time. When pulling out, several symmetrical jackets 4 are inserted from the upper end of the millet seedlings, and then the handle 6 is held and rotated. The handle 6 drives the gear 7 inside the transmission shell 2 to rotate through the transmission rod 5, and the gear 7 drives the racks 8 at both ends to move horizontally. When the rack 8 moves, it drives the symmetrical jackets 4 to clamp the millet seedlings through the movable bar 9 and the connecting piece 10, and then the handle 6 is lifted to pull out several millet seedlings in the same row at one time.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
