Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer mixing equipment, and in particular to a fertilizer mixer. Background Art

[0002] In modern farming, the soil can be analyzed and tested first, and then a fertilizer mixer can be used to prepare a fertilizer suitable for the soil according to the test results for more scientific fertilization. Most of the existing fertilizer mixers are shown in the patent with the application number 201821792199.6 and the name "Fertilizer Mixer", including a frame, a plurality of metering bins respectively used for accommodating and metering different fertilizers, automatic feeding devices corresponding to the metering bins one by one, a first conveying device and a stirring device. The plurality of metering bins are arranged on the frame in sequence, and a plurality of sensors for marking the height of the fertilizer are provided in each metering bin. The first conveying device is arranged at the discharge port of the metering bin for conveying the metered fertilizer to the stirring device, and the stirring device is arranged at the outlet of the first conveying device for stirring and mixing the metered various fertilizers. When in use, a fertilizer bag with an open upper mouth needs to be placed on the flap feeding mechanism in a nearly vertical state, and then the piston rod of the cylinder extends, and the flap feeding mechanism rotates, so that the opening of the fertilizer bag faces obliquely downward, and the fertilizer in the fertilizer bag falls into the feeding bin. However, because the flap is relatively smooth, when the original bottom of the fertilizer bag is higher than its original top, the fertilizer bag will slide along the flap into the feeding bin, resulting in the original upper mouth being pressed and closed, and the fertilizer cannot flow out. To avoid this situation, in actual use, when the original bottom of the fertilizer bag is just about to be higher than its original top, it is necessary to manually lift the original bottom of the fertilizer bag and hold it for a period of time to make the fertilizer completely fall. At this time, the supporting force of the flap mechanism on the fertilizer bag is small, and the operation of lifting the fertilizer bag is relatively laborious and the labor intensity is large. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fertilizer mixer in view of the above-mentioned technical deficiencies.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A fertilizer mixer includes a machine body. A plurality of feed bins are arranged on the front side of the machine body. The top and the front side of the upper part of the feed bin are open. The flap mechanism includes side plates. A bottom plate is arranged at the lower end of the side plates. The upper back side of the side plates is rotatably connected to the lower part of the front side opening of the upper part of the feed bin. A track in the same extending direction as the side plates is arranged on the back side of the side plates. A slider is slidably connected to the track. The piston rod of a cylinder is hinged to the slider. The bottom end of the cylinder is hinged to the lower part of the machine body. Two pushing mechanisms are rotatably connected to the lower side of the bottom plate. The pushing mechanism includes a central shaft. A main gear coaxial with the central shaft and an eccentric wheel not coaxial with the central shaft are arranged on the central shaft. The needle includes a needle body and a pushing frame. The needle body is slidably connected to a through hole on the bottom plate. The eccentric wheel can drive the pushing frame to move along the length direction of the needle body. The inclination directions of the needle bodies on different pushing mechanisms with respect to the top surface of the bottom plate are opposite. A rack is arranged at one end of the slider. The rack is in transmission connection with the main gear through a gear.

[0005] To further optimize the technical solution, a guide sleeve is arranged on the back side of the side plates. The rack is slidably connected to the guide sleeve.

[0006] To further optimize the technical solution, the eccentric wheel is located inside the pushing frame. The eccentric wheel is cylindrical. The width of the pushing frame is equal to the diameter of the eccentric wheel. The length of the pushing frame is greater than the diameter of the eccentric wheel.

[0007] To further optimize the technical solution, two eccentric wheels are arranged on each central shaft, and the two eccentric wheels are respectively located on both sides of the main gear.

[0008] To further optimize the technical solution, the rack meshes with a first gear. The first gear meshes with a main gear. This main gear meshes with a second gear. The second gear meshes with a third gear. The third gear meshes with another main gear. The first gear, the second gear, and the third gear are rotatably connected to the bottom plate.

[0009] Compared with the prior art, the present invention has the following advantages: A track is arranged on the back side of the side plates and a slider is slidably connected to the track. The slider is hinged to the piston rod of the cylinder. A rack is arranged at one end of the slider. When the rack drives the main gear to rotate, the eccentric wheel can drive the needle body to pierce into the bottom of the fertilizer bag. Thus, during the process of feeding materials into the feed bin, when the original bottom of the fertilizer bag is just about to be higher than its original top, there is no need for manual workers to lift and hold the original bottom of the fertilizer bag for a period of time, reducing the labor intensity.

Specific embodiments

[0017] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0018] Specific embodiments: In combination with Figures 1-6As shown in the figure, a fertilizer mixer includes a machine body 1. A plurality of feeding bins 2 are arranged on the front side of the machine body 1. A metering bin corresponding to each feeding bin 2, an automatic feeding device corresponding to each metering bin, a first conveying device, a stirring device, a hopper bin, and a packaging metering device arranged at the lower part of the hopper bin are further arranged in the machine body 1, so as to stir and mix a variety of fertilizers after metering and then pour them into fertilizer bags with manual participation. The top and the upper front side of the feeding bin 2 are open. The flap mechanism 3 includes a side plate 31. A bottom plate 32 is arranged at the lower end of the side plate 31. The upper back side of the side plate 31 is rotatably connected to the lower part of the front side opening of the upper part of the feeding bin 2. A track 33 having the same extending direction as the side plate 31 is arranged on the back side of the side plate 31. A slider 34 is slidably connected to the track 33. The length of the slider 34 is less than the length of the track 33 and the difference between the two is a set value (so as to enable the needle body 371 mentioned later to extend out of the top surface of the bottom plate 32 by the required length). The end of the piston rod of the air cylinder 4 is hinged to the slider 34. A T-shaped groove can be arranged on the track 33. The slider 34 is located at the wider position of the T-shaped groove (the side closer to the side plate 31 of the T-shaped groove is the wider position). The ear plate on the slider 34 extends out of the T-shaped groove and is hinged to the piston rod of the air cylinder 4. The bottom end of the air cylinder 4 is hinged to the lower front side of the machine body 1. Two pushing mechanisms 38 are rotatably connected to the lower side of the bottom plate 32. The pushing mechanism 38 includes a central shaft 381. A main gear 382 coaxial with the central shaft 381 is arranged on the central shaft 381. An eccentric wheel 383 is further arranged on the central shaft 381. The needle 37 includes a needle body 371 and a pushing frame 372. The end of the needle body 371 is a tip that can be inserted into the fertilizer bag. The needle body 371 is slidably connected to the through hole 321 on the bottom plate 32. The eccentric wheel 383 can drive the pushing frame 372 to move along the length direction of the needle body 371. The needle bodies 371 on different pushing mechanisms 38 are inclined in opposite directions to the top surface of the bottom plate 32 (the extending direction of the through hole 321 is inclined to the top surface of the bottom plate 32). A rack 35 is arranged at one end of the slider 34. The rack 35 is in transmission connection with the main gear 382 through a gear so as to drive the pushing mechanism 38 to rotate.

[0019] Preferably, a guide sleeve 36 is arranged on the back side of the side plate 31. The rack 35 is slidably connected to the guide sleeve 36, making the rack 35 more stable.

[0020] Specifically, the eccentric wheel 383 is located inside the pushing frame 372. The eccentric wheel 383 is cylindrical. The width of the pushing frame 372 (the width direction is the length direction of the needle body 371) is equal to the diameter of the eccentric wheel 383. The two sides of the outer circumference of the eccentric wheel 383 are in contact with the two sides in the width direction of the pushing frame 372. The length of the pushing frame 372 is much larger than the diameter of the eccentric wheel 383. During the rotation of the eccentric wheel 383, the pushing frame 372 will not prevent it from continuing to rotate.

[0021] Preferably, two eccentric wheels 383 are arranged on each central shaft 381, and the two eccentric wheels 383 are respectively located on both sides of the main gear 382. Correspondingly, each pushing mechanism 38 can drive two needle inserting parts 37 simultaneously, and the two needle inserting parts 37 are respectively located on both sides in the width direction of the fertilizer bag.

[0022] Specifically, the rack 35 meshes with a first gear, the first gear meshes with a main gear 382, the main gear 382 meshes with a second gear, the second gear meshes with a third gear, the third gear meshes with another main gear 382, and the first gear, the second gear and the third gear are rotatably connected to the bottom plate 32, so that the rack 35 can drive the two main gears 382 to rotate simultaneously.

[0023] During use, with reference to Figure 1 and Figure 2 as shown, at the beginning, the slider 34 contacts the end of the track 33 far away from the bottom plate 32, and the needle body 371 hardly protrudes from the top surface of the bottom plate 32. Place the fertilizer bag with the upper opening on the bottom plate 32 and make one side of it lean against the side plate 31. Operate the device to make the piston rod of the air cylinder 4 extend. The air cylinder 4 pushes the turning plate mechanism 3 to rotate. When the extending direction of the air cylinder 4 is perpendicular to the side plate 31, the side plate 31 has not rotated to the horizontal state yet. The piston rod of the air cylinder 4 continues to extend, and the slider 34 will move along the track 33 towards the direction of the bottom plate 32 until it reaches the end of the track 33. During this process, the rack 35 drives the main gear 382 to rotate, so that the eccentric wheel 383 drives the pushing frame 372 and the needle body 371 to move, and the needle body 371 protrudes from the top surface of the bottom plate 32 and inserts into the bottom of the fertilizer bag (with reference to Figure 6 as shown, preferably when the slider 34 moves to the end of the track 33 close to the bottom plate 32, the needle bodies 371 on the opposite sides form a cross and are relatively close in the axial direction of the central shaft 381. Of course, the tips of the needle bodies 371 on the opposite sides can also be inclined outwards, but it is not as good as inclining inwards and finally forming a cross). The piston rod of the air cylinder 4 continues to extend, and the side plate 31 continues to rotate so that the end with the bottom plate 32 is much higher than the other end. At this time, the open end of the fertilizer bag is much lower than the other end, and the fertilizer inside it falls into the feeding bin 2. Due to the action of the needle body 371, the fertilizer bag will not slide into the feeding bin 2 along the turning plate. Then control the piston rod of the air cylinder 4 to retract, and the side plate 31 rotates back. When the extending direction of the air cylinder 4 is perpendicular to the side plate 31 again, under the action of gravity (and the lever), the slider 34 moves to the end of the track 33 far away from the bottom plate 32, and the eccentric wheel 383 drives the needle body 371 to retract. After that, the empty fertilizer bag can be easily taken away (generally, wait until it returns to the state shown in Figure 1 before taking away the empty fertilizer bag). When it returns to Figure 1After the state shown, it doesn't matter if the needle body 371 is not fully retracted (the reason is that the slider 34 has not moved to the end of the track 33 away from the bottom plate 32. At this time, it is not easy to remove the empty fertilizer bag). You can step on the bottom plate 32 with your foot to make the needle body 371 fully retracted.
