Description

Technical Field

[0001] The present invention relates to the technical field of farmland planting, and in particular to a tractor used for farmland planting operations. Background Art

[0002] With the development of modern agriculture, improving the efficiency of crop planting has become an important issue in agricultural production. Traditional farmland planting operations mainly rely on planting equipment pulled by tractors to complete the sowing task. However, in actual applications, because the seed sizes of different crops are inconsistent, it is necessary to replace the matching seeder for use, so as to prevent the phenomenon of seed jamming caused by the feed and discharge ports of the seeder being too small and the phenomenon of too much seed being discharged at one time caused by the feed and discharge ports of the seeder being too large. But this will cause the following problems:

[0003] Due to the difference in seed size, such as the obvious size difference between potato, corn and other crop seeds, in order to ensure the quality of sowing, it is usually necessary to remove the original seeder from the tractor and install a new one, which not only increases the labor intensity and prolongs the preparation time, but also reduces the work efficiency. In addition, each replacement of the seeder will interrupt the normal sowing process and affect the work rhythm of the entire planting season, especially in the short suitable planting period, this interruption is particularly disadvantageous. Summary of the invention

[0004] In view of this, the present invention provides a tractor for farmland planting operations, which can overcome the shortcomings of existing tractors that, when assisting a seeder in planting crops, different seeders need to be replaced according to the size of seeds, which results in complicated operation and interruption of the normal sowing process, leading to low work efficiency.

[0005] The technical scheme is: a tractor used for farmland planting operations, including a tractor body, a feeding frame, a charging hopper, a top frame, an electric push rod II, a driving assembly and a lifting assembly.

[0007] Furthermore, the lifting assembly includes an electric push rod I and a fixed plate. The electric push rod I is symmetrically arranged on the tractor body. The fixed plate is arranged on the telescopic rod of the electric push rod I, and the unloading frame and the loading hopper are fixedly connected to the fixed plate, so that the electric push rod I can drive the unloading frame and the loading hopper to lift and lower through the fixed plate.

[0008] Furthermore, it also includes a magnetic frame and a material guide frame. The material guide frame is installed on the end of the material discharge frame through magnetic adsorption of the magnetic frame, so that the material guide frame can be changed in size according to different sizes of seeds to adapt to seeds of different sizes for precise material discharge.

[0009] Furthermore, it also includes a loading frame, a connecting pipe, a driving motor II and a screw rod. The loading frame is arranged on the fixed plate, and the connecting pipes are symmetrically arranged inside the fixed plate.

A screw rod is arranged on the output shaft of the driving motor II, and the screw rod is located inside the connecting pipe, so that the driving motor II drives the screw rod to rotate to transport the fertilizer in the connecting pipe to the unloading frame.

[0010] Furthermore, it also includes a mounting rod and a diverter plate. The unloading frame is provided with a mounting rod, and the mounting rod is provided with a diverter plate. The diverter plate is used to push the soil to both sides.

[0011] Furthermore, it also includes a connecting rod and a soil-moving plate. The charging hopper is symmetrically provided with the connecting rod, and the soil-moving plate is provided on the connecting rod.

[0012] Furthermore, the soil-pushing plate is inclined and located on both sides of the horizontal position of the diverter plate, so as to push the soil on both sides of the ditch back into the ditch.

[0013] The beneficial effect is as follows: the present invention can control the rise of a specified number of top frames by controlling the number of telescopic rods of the electric push rod II passing through the card slots, thereby controlling the top surface area of ​​the rising top frames, and then being able to adapt to the use of seeds of different sizes. In this way, no matter how big the seeds are, a certain number of seeds can be lifted up by the top frame for loading, without the need to replace different sowing equipment, saving time and effort and improving work efficiency.

[0027] Embodiment: A tractor for farmland planting operations, such as Figure 1-Figure 4 As shown, it includes a tractor body 1, a feeding frame 2, a charging hopper 3, a top frame 4, an electric push rod II 5, a driving assembly and a lifting assembly. Two feeding frames 2 and a charging hopper 3 are arranged on the right side of the upper part of the tractor body 1, and the feeding frames 2 and the charging hopper 3 are inclined. The two feeding frames 2 are located on the left side of the charging hopper 3. The upper and lower ends of the feeding frame 2 are both open-type designs, and a feeding port 201 is opened on the upper right side of the feeding frame 2. The feeding port 201 is located on the upper left side of the charging hopper 3, and the bottom height of the feeding port 201 is at the same height plane as the left side of the top surface of the charging hopper 3. The front and rear sides of the charging hopper 3 are divided into two storage spaces to adapt to the use of the two feeding frames 2, and the front, back, left and right sides of the inner wall of the storage space are all inclined surfaces, so as to gather the seeds in the storage space in the middle of the bottom of the storage space. A group of top frames 4 are arranged on the front and back sides of the lower part of the charging hopper 3, and the number of top frames 4 in each group is seven. The seven top frames 4 in the same group are designed in a nesting doll style from the inside to the outside in the horizontal direction (such as Figure 3As shown), and two adjacent top frames 4 can slide up and down with each other, each top frame 4 is provided with a card slot 401, and each card slot 401 is located on the same horizontal line and is interconnected, an electric push rod Ⅱ5 is installed on the lower side of the innermost top frame 4, and the telescopic rod of the electric push rod Ⅱ5 is located in the card slot 401 of the innermost top frame 4, the driving component is used to drive the top frame 4 to rise, so as to lift the seeds in the charging hopper 3 to the feed port 201 for loading, and the lifting component is used to drive the unloading frame 2 and the charging hopper 3 to rise and fall, so as to control the height of the unloading frame 2 and the charging hopper 3; the driving component includes a mounting plate 6, a driving motor Ⅰ7 and a screw 8, and the bottom of the charging hopper 3 is symmetrically fixed with a mounting plate in the front and rear. 6. Drive motors Ⅰ7 are installed on the two mounting plates 6. Screw rods 8 are connected to the output shafts of the two drive motors Ⅰ7. The two screw rods 8 correspond to the two sets of top frames 4 one by one, and the screw rods 8 are threadedly connected to the lower part of the innermost top frame 4, so that the drive motor Ⅰ7 drives the screw rod 8 to rotate to control the innermost top frame 4 to be lifted; the lifting assembly includes an electric push rod Ⅰ9 and a fixed plate 10. The electric push rods Ⅰ9 are symmetrically installed on the right side of the tractor body 1. The fixed plate 10 is fixedly connected between the telescopic rods of the two electric push rods Ⅰ9, and the unloading frame 2 and the loading hopper 3 are fixedly connected to the fixed plate 10, so that the electric push rod Ⅰ9 can drive the unloading frame 2 and the loading hopper 3 to be lifted through the fixed plate 10.

[0028] like Figure 4 and Figure 5 As shown, it also includes a magnetic frame 11 and a material guiding frame 12. The material of the material frame 2 is iron, so that the magnetic frame 11 can be adsorbed on the lower end of the material frame 2 by magnetic force. The material guiding frame 12 is connected inside the magnetic frame 11. The top surface shape of the material guiding frame 12 is adapted to the bottom surface shape of the material frame 2, so that the top surface of the material guiding frame 12 and the bottom surface of the material frame 2 can fit tightly together, thereby preventing seeds from being stuck between the material guiding frame 12 and the material frame 2, and the magnetic frame 11 is hollow, so as not to affect the material in the material frame 2 from falling down into the material guiding frame 12. The inner wall of the material guiding frame 12 is an inclined surface, and the lower end opening of the material guiding frame 12 is smaller than the upper end opening, thereby guiding the material in the material guiding frame 12 for centralized material discharge.

[0029] like Figure 6As shown, it also includes a loading frame 13, a connecting pipe 14, a driving motor II 15 and a screw rod 16. The loading frame 13 is fixedly connected to the left side of the top surface of the fixed plate 10, and the loading frame 13 is located on the left side of the unloading frame 2. The front and rear sides of the fixed plate 10 are connected with connecting pipes 14. The top surfaces of the two connecting pipes 14 are each provided with a notch 1401 connected to the inside of the loading frame 13, so that the fertilizer in the loading frame 13 can fall from the notch 1401 into the connecting pipe 14 through gravity, and the right ends of the two connecting pipes 14 respectively pass through the left sides of the two unloading frames 2, and the left ends of the two connecting pipes 14 are both installed with a driving motor II 15, and the output shaft of the driving motor II 15 is connected to the screw rod 16, and the screw rod 16 is located inside the connecting pipe 14, so that the driving motor II 15 drives the screw rod 16 to rotate to transport the fertilizer in the connecting pipe 14 to the unloading frame 2.

[0030] like Figure 7 and Figure 8 As shown, it also includes a mounting rod 17, a diverter plate 18, a connecting rod 20 and a soil-pushing plate 21. The mounting rod 17 is fixedly connected to the middle of the left side of the two feeding frames 2, and the bottom surface of the mounting rod 17 is fixedly connected to the diverter plate 18. The bottom surface height of the diverter plate 18 gradually increases from left to right so that the lower end of the diverter plate 18 is inserted into the soil, and the front and rear sides of the diverter plate 18 are both inclined surfaces for pushing the soil to the front and rear sides. The bottom surfaces of the two charging hoppers 3 are symmetrically fixedly connected to the connecting rod 20, and the lower part of the connecting rod 20 is fixedly connected to the soil-pushing plate 21. The feeding frame 2 is located on the right side of the diverter plate 18. The four soil-pushing plates 21 are all inclined, and the spacing between the two soil-pushing plates 21 on the same charging hopper 3 gradually decreases from left to right (such as Figure 8 As shown in the figure, the two soil-pushing plates 21 on the same loading hopper 3 correspond to the diverter plate 18, and the two soil-pushing plates 21 on the same loading hopper 3 are respectively located at the front and rear sides of the horizontal position of the corresponding diverter plate 18 to push the soil on both sides of the ditch back into the ditch.

[0031] When sowing two ridges of land, first control the tractor body 1 to move to the specified position so that the two diverter plates 18 are aligned with the two ridges of land respectively, then select the seeds, and then select the guide frame 12 of appropriate size according to the size of the seeds, and then install the guide frame 12 at the lower end of the unloading frame 2 through the magnetic force of the magnetic frame 11, so that the top surface of the guide frame 12 fits with the bottom surface of the unloading frame 2, and then control the telescopic rod of the electric push rod II5 to extend and retract according to the size of the seeds, so as to control the number of slots 401 that the telescopic rod of the electric push rod II5 passes through (the larger the seeds, the more slots 401 that the telescopic rod of the electric push rod II5 needs to pass through). When the telescopic rod of the electric push rod II5 passes through the appropriate number of slots 401, an appropriate amount of seeds can be sown. Pour it into the loading hopper 3, the seeds in the loading hopper 3 are all located above the top frame 4, and then pour an appropriate amount of fertilizer into the loading frame 13, and the fertilizer in the loading frame 13 will fall into the connecting pipe 14 through the notch 1401; then drive the fixing plate 10 to move downward through the electric push rod Ⅰ9, and the fixing plate 10 can drive the unloading frame 2 and the loading hopper 3 to move downward, thereby driving the mounting rod 17, the diverter plate 18, the connecting rod 20 and the soil-moving plate 21 to move downward until the diverter plate 18 is inserted into the raised soil, and then control the tractor body 1 to move, thereby driving the diverter plate 18 to move in the raised soil, and then the raised soil can be squeezed to the front and rear sides, and the squeezed soil will move outward along the front and rear sides of the diverter plate 18. , so as to shovel out a ditch in the soil, and at the same time, the screw rod 8 can be driven by the driving motor Ⅰ7 to rotate back and forth, and the screw rod 8 can drive the innermost top frame 4 to reciprocate up and down. The innermost top frame 4 can drive the other specified number of top frames 4 to move up and down synchronously through the action of the electric push rod Ⅱ5. The rising of the top frame 4 can pass through the seeds in the charging hopper 3, and finally the seeds left on the top surface of the top frame 4 will be separated from the seeds in the charging hopper 3, until the seeds on the top surface of the top frame 4 rise to the feeding port 201 of the lower feeding frame 2, the seeds on the top surface of the top frame 4 will slide to the left due to gravity into the lower feeding frame 2, and the seeds in the lower feeding frame 2 will pass through the magnetic frame 11 and the guide frame 12 in turn and fall into the ditch, and so on and so forth, which can be intermittent. The seeds in the hopper 3 are automatically fed into the ditch. At the same time, the screw rod 16 can be driven to rotate intermittently by the driving motor II 15. The screw rod 16 can intermittently transport the fertilizer in the connecting pipe 14 to the feeding frame 2. Then the fertilizer can also fall down into the ditch along the feeding frame 2, the magnetic frame 11 and the guide frame 12, so that the fertilizer can be intermittently fed into the ditch. The feeding time of the fertilizer is between the two feeding times of the seeds, so that the fertilizer can be sown between the two groups of seeds to prevent the seeds from being burned by direct contact with the fertilizer. Then the soil-pushing plate 21 will move to contact with the raised soil, so that the soil on both sides of the ditch can be pushed inward, and then the seeds and fertilizer can be automatically buried to complete the seed planting work;By controlling the specified number of top frames 4 to rise, the top surface area of ​​the rising top frame 4 can be controlled. When the volume of a single seed is larger, the top surface area of ​​the top frame 4 needs to be increased. On the contrary, when the volume of a single seed is smaller, the top surface area of ​​the top frame 4 needs to be reduced. In this way, regardless of the volume of the seeds, the number of seeds loaded each time can be controlled within a certain range. ;

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
