Technical Field
[0001] This utility model relates to the technical field of seeder feeding equipment, and in particular to an automatic fertilizer feeding device for a seeder. Background Technology
[0002] Currently, most major grain-producing areas in my country grow wheat and corn. With the development of agricultural mechanization, wheat and corn are generally sown mechanically. Wheat and corn fertilizer planters are widely welcomed by farmers because they reduce the labor intensity of farmers, improve seed germination rate, and reduce the occurrence of pests and diseases. However, the fertilizer tanks of fertilizer planters on the agricultural machinery market today are relatively high, requiring the machine to be stopped midway to replenish fertilizer. Due to the height of the fertilizer tank, operators usually have to carry fertilizer bags on their shoulders and climb to the side of the fertilizer tank to replenish fertilizer. This is labor-intensive and slow, affecting the normal operating efficiency of the planter. Utility Model Content
[0003] This utility model provides an automatic fertilizer feeding device for a seeder, which solves the problems of time-consuming and labor-intensive fertilizer feeding, high manual labor intensity, and low efficiency in traditional integrated seeding and fertilization machines.
[0004] This utility model provides an automatic fertilizer feeding device for a seeder, including an inclined lifting pipe. The upper end of the lifting pipe is connected to two fertilizer boxes via a three-way distributor, and the lower end is connected to a feeding hopper. A spiral conveying shaft is installed inside the lifting pipe, and both ends of the spiral conveying shaft are rotatably connected to end caps at both ends of the lifting pipe. Spiral blades are installed on the spiral conveying shaft. A positioning pipe is coaxially installed at the upper end of the lifting pipe, and the lower end of the positioning pipe is fixedly connected to the upper end of the lifting pipe. A hydraulic motor is fixedly installed at the upper end of the positioning pipe, and the output shaft of the hydraulic motor is connected to the upper end of the spiral conveying shaft via a first coupling. A feeding screen plate is installed inside the feeding hopper, and a feeding port is provided on the lower side wall of the lifting pipe. The feeding port is connected to the discharge port provided on the bottom sealing plate of the feeding hopper.
[0005] In the above technical solution, the lifting pipe is further fixedly connected to the rear side of the frame of the seeding and fertilizing integrated machine.
[0006] In the above technical solution, a horizontal rotating shaft is further provided below the feeding screen plate in the feeding hopper. The two ends of the rotating shaft are rotatably connected to the two side walls of the feeding hopper. Two spiral blades with opposite spiral directions are symmetrically arranged on the rotating shaft. A drive mechanism for driving the rotating shaft to rotate is provided on the outer side wall of the feeding hopper.
[0007] In the above technical solution, the driving mechanism further includes a fixed plate, a drive motor, and a second coupling. The fixed plate is horizontally arranged on the outer side wall of the feeding hopper, and the drive motor is arranged on the fixed plate. The output shaft of the drive motor is connected to the extended end of the rotating shaft through the second coupling.
[0008] In the above technical solution, a vibration shaft is further provided above the rotating shaft, and the two ends of the vibration shaft are rotatably connected to the two side walls of the feeding hopper, respectively. A first pulley is coaxially provided on the end of the vibration shaft extending out of the feeding hopper, and a second pulley is coaxially provided on the rotating shaft on one side of the first pulley. The first pulley and the second pulley are connected and driven by a transmission belt, and multiple vibration blocks are spaced apart along the axial direction on the vibration shaft.

[0013] 2. By installing a feeding device on the rear side of the seeder, the structure is compact, occupies little space, and does not affect the normal operation of the seeder;
[0014] 3. The rotating shaft is driven by a drive motor, which drives two spiral blades to convey fertilizer from both sides to the middle, so that the fertilizer gathers at the feed inlet, which facilitates the increase of fertilizer feeding efficiency.

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0029] Example 1:
[0030] See Figure 1-6An automatic fertilizer feeding device for a seeder includes an inclined lifting pipe 1. The upper end of the lifting pipe 1 is connected to two fertilizer boxes 2 through two discharge ports of a three-way distributor 10, and the lower end is connected to a feeding hopper 3. A spiral conveying shaft 11 is coaxially arranged inside the lifting pipe 1. The two ends of the spiral conveying shaft 11 are rotatably connected to bearings in bearing seats provided on the end caps at the upper and lower ends of the lifting pipe 1, respectively. Spiral blades 12 are fixedly arranged on the outer wall of the spiral conveying shaft 11. A positioning pipe 13 is coaxially arranged at the upper end of the lifting pipe 1. The lower end of the positioning pipe 13 is fixedly connected to the end cap at the upper end of the lifting pipe 1. A hydraulic motor 14 is fixedly arranged on the end face sealing plate at the upper end of the positioning pipe 13. The output shaft of the hydraulic motor 14 is connected to the upper end of the spiral conveying shaft 11 through a first coupling 15 inside the positioning pipe 13. A horizontal feeding screen plate 4 is provided inside the feeding hopper 3. A feeding port 16 is provided on the top side wall at the lower end of the lifting pipe 1. The feeding port 16 is connected to the discharge port provided on the bottom side plate of the feeding hopper 3. By pouring fertilizer into the feeding hopper 3, the screw conveyor shaft 11 and screw blades 12 inside the lifting pipe 1 are driven to rotate by the pressure motor 14. The fertilizer at the lower end of the lifting pipe 1 is tilted and screwed up and conveyed to the two fertilizer boxes 2. The material in the feeding hopper 3 can automatically enter the lifting pipe 1 for lifting and feeding, which reduces the intensity of manual labor and improves the conveying efficiency.
[0031] In the above embodiments, specifically, see [link to specific examples]. Figure 6 The lifting pipe 1 is welded and fixedly connected to the rear side of the frame 51 of the seeding and fertilizing machine 5.
[0032] In the above embodiments, specifically, see [link to specific examples]. Figure 3 , 4 A horizontal rotating shaft 31 is horizontally arranged below the feeding screen plate 4 inside the feeding hopper 3. The two ends of the rotating shaft 31 are rotatably connected to the bearing supports on the two side walls of the feeding hopper 3. Two spiral blades 34 with opposite spiral directions are symmetrically arranged on the rotating shaft 31. A drive mechanism 32 for driving the rotating shaft 31 is arranged on the outer side wall of the feeding hopper 3. The rotating shaft 31 is driven to rotate by the drive mechanism 32, which drives the two spiral blades 34 to transport the material in the feeding hopper 3 from both sides to the middle, so that the fertilizer enters the lifting pipe 1 from the feed inlet 16 and is lifted, which increases the discharge speed of the feeding hopper 3.
[0033] In the above embodiments, more specifically, see [link to relevant documentation]. Figure 3 The drive mechanism 32 includes a fixed plate 321, a drive motor 322, and a second coupling 323. The fixed plate 321 is horizontally arranged on the outer side wall of the feeding hopper 3. The drive motor 322 is arranged on the fixed plate 321. The output shaft of the drive motor 322 extends through the side wall of the feeding hopper 3 to the outside of the feeding hopper 3 and is connected to the outer end of the rotating shaft 31 through the second coupling 323.
[0034] In the above embodiments, more specifically, see [link to relevant documentation]. Figure 3A vibrating shaft 33 is installed above the rotating shaft 31. The two ends of the vibrating shaft 33 are rotatably connected to the two side walls of the feeding hopper 3. The vibrating shaft 33 extends out of the end of the feeding hopper 3 and is coaxially equipped with a first pulley 331. A second pulley 332 is coaxially equipped on the rotating shaft 31 on one side of the first pulley 331. The first pulley 331 and the second pulley 332 are connected and driven by a transmission belt 333. Multiple vibrating blocks 334 are spaced apart along the axial direction on the vibrating shaft 33. The rotating shaft 3 is driven to rotate by a drive motor 322. The rotating shaft 3 drives the vibrating shaft 33 to rotate through the first pulley 331, the second pulley 332, and the transmission belt 333. During the rotation of the vibrating shaft 33, the vibrating blocks 334 act on the feeding screen plate 4 to vibrate the fertilizer on the feeding screen plate 4, so that the fertilizer passes evenly through the screen holes of the feeding screen plate 4 and falls to the bottom of the feeding hopper 3, preventing the feeding screen plate 4 from being blocked.
[0035] In the above embodiments, preferably, two pivot shafts (not shown in the figure) are provided on the two rear side walls of the feed screen plate 4. The two pivot shafts are respectively inserted into the corresponding pivot holes provided on the two side walls of the feeding hopper 3 and rotated. The rear end of the feed screen plate 4 can also be hinged to the rear side wall of the feeding hopper 3. Since the feeding hopper 3 is an open structure with a larger top and a smaller bottom, the feed screen plate 4 is installed in the feeding hopper 3 and is restricted by the four side walls of the feeding hopper 3 to be suspended and supported. The front end of the feed screen plate 4 can be flipped up and opened. When the feed screen plate 4 vibrates, the fertilizer can pass through the screen holes of the feed screen plate 4 and fall evenly, which speeds up the feeding speed.
[0036] In the above embodiments, see Figure 3 , 5 The vibrating block 334 includes a positioning bushing 335 and a boss 336. Two bosses 336 are arranged on the side wall of the positioning bushing 335 along the circumferential direction. During the rotation of the vibrating block 334, the bosses 336 lift the feed screen plate 4 and lower it, allowing the fertilizer on the feed screen plate 4 to quickly pass through the screen holes and enter the inside of the lifting pipe 1.
[0037] As can be seen from the above technical solution, when in use, bagged fertilizer is poured into the feeding hopper 3. The controller controls the hydraulic motor 14 to drive the spiral conveying shaft 11 and spiral blades 12 in the lifting pipe 1 to rotate, so that the fertilizer at the lower end of the lifting pipe 1 is inclined and spirally lifted and conveyed to the two fertilizer boxes 2. The controller controls the drive motor 322 to drive the rotating shaft 31 to rotate, which drives the two spiral blades 34 to spirally convey the fertilizer on both sides to the middle, so that the fertilizer gathers at the feed inlet 16, which facilitates the increase of fertilizer feeding efficiency. This realizes that the material in the feeding hopper 3 can automatically enter the lifting pipe 1 for lifting and feeding, reducing the intensity of manual labor and improving the conveying efficiency.
