Abstract
Description
Technical Field
[0001] This utility model relates to the field of tiller technology, specifically a corn tiller and seedling protector. Background Technology
[0002] Inter-row cultivation machinery mainly refers to machinery used during crop growth for weeding, loosening soil, breaking up compacted topsoil, hilling, or performing fertilization while carrying out the above operations. It includes full-row cultivators, inter-row cultivators, and specialized cultivators. Full-row cultivators are used for pre-planting land preparation, fallow land management, and the mixing of fertilizers and pesticides. Inter-row cultivation of crops includes loosening soil, breaking up compacted topsoil, thinning seedlings, weeding, topdressing, and ditching and hilling between rows. Some specialized cultivators are used for specific operations in orchards, tea gardens, and rubber plantations. When performing inter-row cultivation on corn, a corn cultivation protector is required.
[0003] Existing corn cultivators and seedling protectors require manual adjustment of the adjustment frames on both sides of the cultivator when adjusting the width. During the adjustment process, the movement distance of the adjustment frames needs to be manually controlled. However, it is difficult for humans to accurately control the movement distance of the adjustment frames, which can easily lead to uneven lengths at both ends of the cultivator after adjustment. Since the mounting frame is connected to the agricultural machine and is located in the middle of the agricultural machine, the agricultural machine needs to move in the middle of the corn rows during operation. Therefore, during cultivation, the cultivator is prone to shifting to one side, affecting the operation effect. Utility Model Content
[0004] The purpose of this utility model is to provide a corn inter-tiller seedling protector, which has the feature of accurately adjusting the adjustment frames on both sides of the inter-tiller to prevent the inter-tiller from shifting and affecting the operation effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a corn inter-cultivator and seedling protector, comprising two mounting bars distributed front and rear, the two mounting bars being fixed together by a connecting rod, each of the two mounting bars having a through-hole communicating with the outside, each of the two sliding holes having two left and right-distributed adjusting rods slidably connected inside, one end of each of the adjusting rods extending to the outside of the two sliding holes, the front and rear adjusting rods being fixed together by a connecting rod, the multiple adjusting rods being grouped into two groups of two, and the outer walls of the two groups of adjusting rods being provided with inter-cultivation mechanisms located on the left and right sides of the two mounting bars;
[0006] The sliding hole at the rear has two fixed plates that are distributed on the left and right. A bidirectional screw is rotatably connected between the two fixed plates. The two adjusting rods at the rear have threaded holes on their opposite side walls. The two ends of the bidirectional screw extend into the two threaded holes and are threadedly connected to them. A first bevel gear located between the two fixed plates is fixedly connected to the outer wall of the bidirectional screw.
[0007] In order to enable land operations, as a preferred embodiment of the corn inter-cultivation and seedling protection device of this utility model, the inter-cultivation operation mechanism includes two first mounting rings that are sleeved on the outer wall of the rear adjustment rod and distributed on the left and right. The lower end face of each of the two first mounting rings is rotatably connected to a mounting rod through a hinge seat. The other end of each of the two mounting rods is rotatably connected to a soil crushing wheel. The two first mounting rings and the two mounting rods are movably connected to a damping rod through a hinge seat.
[0008] The tillage mechanism also includes a second mounting ring sleeved on the outer wall of the rear adjusting rod and located between the two first mounting rings. Two third mounting rings distributed on the left and right are sleeved on the outer wall of the front adjusting rod. The front ends of the second mounting ring and the two third mounting rings are fixedly connected to fixing rings. Vertical rods are slidably connected inside the multiple fixing rings. The lower ends of the multiple vertical rods extend to the bottom of the fixing rings and are fixedly connected to hoes.
[0009] In order to drive the first bevel gear to rotate, as a preferred embodiment of the corn cultivation and seedling protection device of this utility model, a second bevel gear is rotatably connected to the upper end of the inner side of the sliding hole at the rear, located between two fixed plates and meshing with the first bevel gear. The rotation shaft of the first bevel gear extends to the top of the rear mounting bar and is fixedly connected to a torsion block.
[0010] In order to limit the movement of multiple adjusting rods, as a preferred embodiment of the corn cultivation and seedling protection device of this utility model, the multiple adjusting rods are slidably connected to the two sliding holes by limiting sliders and limiting grooves.
[0011] To facilitate the connection of the inter-row cultivator and seedling protector to agricultural machinery, a preferred embodiment of this utility model of a corn inter-row cultivator and seedling protector has an installation frame installed on the rear end face of the rear mounting bar.
[0012] In order to fix the two first mounting rings, the second mounting rings and the two third mounting rings, as a preferred embodiment of the corn inter-cultivation seedling protector of this utility model, the upper end faces of the two first mounting rings, the second mounting rings and the two third mounting rings are all threadedly connected with first bolts that abut against the outer walls of the front and rear adjusting rods, and the front end faces of the plurality of fixing rings are all threadedly connected with second bolts that abut against the outer wall of the vertical rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] When adjusting the distance between the two tillage mechanisms, the bidirectional screw, in conjunction with the two threaded holes, drives the two rear adjusting rods to move in opposite directions. Through the two connecting rods, the two front adjusting rods can move synchronously with the two rear adjusting rods. This, in turn, in conjunction with the two sets of adjusting rods moving in opposite directions, drives the two tillage mechanisms to move, thereby adjusting the distance between them. The bidirectional screw ensures that the two rear adjusting rods move synchronously, allowing for accurate adjustment of the two tillage mechanisms and preventing the tiller from shifting, which would affect the working effect.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Furthermore, in the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0020] Please see Figures 1 to 3A corn inter-row cultivation and seedling protection device includes two mounting bars 1 distributed front and back, which are fixed together by a connecting rod. Each mounting bar 1 has a sliding hole 2 that communicates with the outside. Each sliding hole 2 is slidably connected to two adjusting rods 3 distributed left and right. One end of each adjusting rod 3 extends to the outside of the two sliding holes 2. The front and back adjusting rods 3 are fixed together by a connecting rod. The front and back adjusting rods 3 are grouped into two groups. The outer walls of the two groups of adjusting rods 3 are provided with inter-row cultivation mechanisms located on the left and right sides of the two mounting bars 1.
[0021] Two fixed plates 4 are fixedly connected inside the rear sliding hole 2, which are distributed on the left and right. A bidirectional screw 5 is rotatably connected between the two fixed plates 4. Threaded holes 6 are opened on the opposite side walls of the two rear adjusting rods 3. The two ends of the bidirectional screw 5 extend into the interior of the two threaded holes 6 and are threadedly connected to the threaded holes 6. A first bevel gear 7 located between the two fixed plates 4 is fixedly connected to the outer wall of the bidirectional screw 5.
[0022] In this embodiment: When in use, the inter-tiller seedling protector is first connected to the agricultural machinery through the mounting frame 19, and then the inter-tiller seedling protector is moved by the agricultural machinery. During the movement, the inter-tiller operation is carried out through the inter-tiller mechanism.
[0023] When adjusting the distance between the two tillage mechanisms, the first bevel gear 7 rotates, which drives the double-headed screw 5 to rotate. The double-headed screw 5, in conjunction with the two threaded holes 6, drives the two rear adjusting rods 3 to move in opposite directions. Since the two front and rear adjusting rods 3 are fixed together by connecting rods, the two connecting rods can drive the two front adjusting rods 3 to move synchronously with the two rear adjusting rods 3. In turn, the two sets of adjusting rods 3 moving in opposite directions drive the two tillage mechanisms to move, thereby adjusting the distance between the two tillage mechanisms.
[0024] The bidirectional screw 5 enables the two rear adjusting rods 3 to move synchronously (the bidirectional screw 5 and the threaded hole 6 have a self-locking effect, and the mutual cooperation between the bidirectional screw 5 and the threaded hole 6 positions the adjusted adjusting rods 3 after adjustment, preventing the adjusting rods 3 from moving randomly), thereby accurately adjusting the two tillage mechanisms and avoiding deviation of the tiller, which would affect the working effect.
[0025] As a technical optimization of this utility model, the tillage operation mechanism includes two first mounting rings 8 that are sleeved on the outer wall of the rear adjustment rod 3 and distributed on the left and right. The lower end face of the two first mounting rings 8 is rotatably connected to the mounting rod 9 through the hinge seat. The other end of the two mounting rods 9 is rotatably connected to the soil crushing wheel 10. The two first mounting rings 8 and the two mounting rods 9 are movably connected to the damping rod 11 through the hinge seat.
[0026] The tillage mechanism also includes a second mounting ring 12 sleeved on the outer wall of the rear adjusting rod 3 and located between the two first mounting rings 8. Two third mounting rings 13, distributed left and right, are sleeved on the outer wall of the front adjusting rod 3. The front ends of the second mounting ring 12 and the two third mounting rings 13 are fixedly connected to the fixing rings 14. Vertical rods 15 are slidably connected inside the multiple fixing rings 14. The lower ends of the multiple vertical rods 15 extend to the bottom of the fixing rings 14 and are fixedly connected to the hoe 16.
[0027] In this embodiment: during the movement, the land can be worked on by multiple hoes 16, and the larger soil clods can be broken up by two soil crushing wheels 10. At the same time, the soil turned over during the operation can be blocked to prevent the soil from rolling down onto the corn seedlings and pressing down on them.
[0028] The two first mounting rings 8 facilitate the adjustment of the distance between the two soil-breaking wheels 10. The two damping rods 11 enable the two soil-breaking wheels 10 to move up and down, allowing them to adapt to different terrains. The second mounting ring 12 and the two third mounting rings 13 facilitate the adjustment of the distance between the multiple hoes 16. The multiple vertical rods 15 facilitate the adjustment of the height of the multiple hoes 16.
[0029] As a technical optimization of this utility model, a second bevel gear 17 is rotatably connected to the upper end of the rear sliding hole 2, located between the two fixed plates 4 and meshing with the first bevel gear 7. The rotation shaft of the second bevel gear 17 extends to the top of the rear mounting bar 1 and is fixedly connected to a torsion block 18.
[0030] In this embodiment: the torsion block 18, in conjunction with the rotating shaft of the second bevel gear 17, drives the second bevel gear 17 to rotate, and the second bevel gear 17 drives the first bevel gear 7 to rotate.
[0031] As a technical optimization of this utility model, multiple adjusting rods 3 are slidably connected to two sliding holes 2 through limiting sliders and limiting grooves.
[0032] In this embodiment, the limiting slider and the limiting groove can limit the multiple adjusting rods 3 to prevent the multiple adjusting rods 3 from sliding out of the two sliding holes 2.
[0033] As a technical optimization of this utility model, a mounting bracket 19 is installed on the rear end face of the rear mounting bar 1.
[0034] In this embodiment, the mounting bracket 19 facilitates the connection of the tiller and seedling protector to agricultural machinery.
[0035] As a technical optimization of this utility model, the upper end faces of the two first mounting rings 8, the second mounting ring 12 and the two third mounting rings 13 are all threadedly connected with first bolts 20 that abut against the outer walls of the front and rear adjusting rods 3, and the front end faces of the multiple fixing rings 14 are all threadedly connected with second bolts 21 that abut against the outer wall of the vertical rod 15.
[0036] In this embodiment: multiple first bolts 20 can fix two first mounting rings 8, two second mounting rings 12 and two third mounting rings 13, and multiple second bolts 21 can fix multiple vertical rods 15.
[0037] Working principle: When in use, first connect the tiller and seedling protector to the agricultural machinery through the mounting frame 19, and then move the tiller and seedling protector through the agricultural machinery. During the movement, multiple hoes 16 can work on the land, and two soil crushing wheels 10 can break up larger soil clods while blocking the soil turned over during the operation to prevent the soil from rolling down onto the corn seedlings and pressing them down.
[0038] When adjusting the distance between the two tillage mechanisms, the torsion block 18, in conjunction with the rotating shaft of the second bevel gear 17, drives the second bevel gear 17 to rotate. The second bevel gear 17, in conjunction with the first bevel gear 7, drives the bidirectional screw 5 to rotate. The bidirectional screw 5, in conjunction with the two threaded holes 6, drives the two rear adjusting rods 3 to move in opposite directions. Since the two front and rear adjusting rods 3 are fixed together by connecting rods, the two connecting rods can drive the two front adjusting rods 3 to move synchronously with the two rear adjusting rods 3. In turn, the two sets of adjusting rods 3 moving in opposite directions drive the two tillage mechanisms to move, thereby adjusting the distance between the two tillage mechanisms.
[0039] The bidirectional screw 5 enables the two adjusting rods 3 located at the rear to move synchronously, thereby accurately adjusting the two tillage mechanisms and preventing the tiller from shifting and affecting the working effect.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
