Description

Technical Field

[0001] The present application relates to the field of continuous material conveying devices, and in particular to a continuous quantitative material delivery device. Background Art

[0002] With the rapid development of agricultural modernization, chemical fertilizers play a vital role in agricultural production. Through scientific fertilization, we can effectively improve soil quality, increase crop yields, and even optimize the quality of agricultural products. However, in the actual production process of fertilizers, the precise ratio of raw materials has become a problem that needs to be solved urgently.

[0003] At present, my country's total fertilizer production and consumption ranks first in the world, but the utilization rate of fertilizers is only about 35%, which shows that there are certain problems in the production and application of fertilizers, including insufficient ratio accuracy. Many fertilizer manufacturers still use the traditional delivery method, that is, relying on manual grasping of raw materials for ratioing. The accuracy of the ratio is directly related to the quality of the fertilizer. If the ratio of raw materials is inaccurate, it will not only affect the nutritional effect of the fertilizer, but may even have a negative impact on the soil, thereby affecting the growth of crops. In addition, frequent ratio errors will increase production costs and reduce production efficiency. For modern agriculture that pursues high efficiency and high quality, this is obviously a considerable obstacle.

[0004] Regarding the above-mentioned related technologies, manual raw material grabbing is adopted, which may lead to errors in each ratio. The biggest problem of this method is that it is too subjective, because people's vision, touch and even mental state will affect the accuracy of grabbing, which makes it impossible to guarantee the accuracy of fertilizer ratio.

[0034] The present application embodiment discloses a continuous quantitative feeding conveying device. Figure 1A continuous quantitative unloading conveying device includes a support 1 and a plurality of receiving barrels 5 of the same size for receiving materials. A loading conveyor belt 2 and a unloading conveyor belt 3 are fixed on the support 1 and are located on the same horizontal plane. The length direction of the loading conveyor belt 2 is parallel to the length direction of the unloading conveyor belt 3, and the rotation direction of the loading conveyor belt 2 is opposite to that of the unloading conveyor belt 3. The receiving barrel 5 is placed on both the loading conveyor belt 2 and the unloading conveyor belt 3, and can drive the receiving barrel 5 to move. The loading conveyor belt 2 and the unloading conveyor belt 3 are respectively provided with driving shafts on the inner sides of both ends along the length direction. A second motor (not shown in the figure) is coaxially fixed to one of the driving shafts of the loading conveyor belt 2, and the loading conveyor belt 2 is driven by the rotation of the driving roller fixed by the second motor; a third motor (not shown in the figure) is coaxially fixed to one of the driving shafts of the unloading conveyor belt 3, and the unloading conveyor belt 3 is driven by the rotation of the driving roller fixed by the third motor.

[0035] The rotation speed of the loading conveyor belt 2 driven by the second motor is lower than the rotation speed of the unloading conveyor belt 3 driven by the third motor, which speeds up the work rhythm of the entire production line and improves the production efficiency. The slower loading conveyor belt 2 can provide sufficient buffer time for the unloading operation; while the faster unloading conveyor belt 3 can ensure that the receiving bucket 5 that has completed unloading leaves in time to avoid interference with subsequent operations. And the running speed of the unloading conveyor belt 3 is faster than the rotation speed of the turntable 41.

[0036] A feeding device 4 is provided on the bracket 1 at a position close to both the feeding conveyor belt 2 and the feeding conveyor belt 3. A turntable 41 and a loading track 42 are coaxially provided on the feeding device 4. The axis of the turntable 41 is vertically provided, and the height of the turntable 41 is higher than the loading track 42. A first motor 43 is coaxially fixedly connected to the turntable 41 directly below the turntable 41, and the first motor 43 drives the turntable 41 to rotate around the axis. A plurality of placement grooves 411 are provided on the circumference of the turntable 41, and the placement grooves 411 are provided at both ends of the turntable 41 along the axial direction. The placement grooves 411 are arc-shaped, and the placement grooves 411 match the circumferential dimensions of the receiving barrel 5.

[0037] The loading track 42 is arranged in a C shape, one end of the loading track 42 abuts against one end of the loading conveyor belt 2, and the loading conveyor belt 2 drives the receiving bucket 5 to move in the direction close to the loading track 42; the other end of the loading track 42 abuts against a section of the unloading conveyor belt 3, and the unloading conveyor belt 3 drives the receiving bucket 5 to move in the direction away from the loading track 42. The loading track 42 is rotatably connected along the width direction of its own track with a plurality of horizontal rollers 421, and the distance between two adjacent horizontal rollers 421 is less than the ground radius of the receiving bucket 5. The uppermost side of the circumference of the horizontal roller 421 is in the same horizontal plane as the loading conveyor belt 2 and the unloading conveyor belt 3. A plurality of vertical rollers 422 are rotatably connected above the side of the loading track 42 away from the turntable 41, and the circumference of the vertical roller 422 close to the turntable 41 can abut against the receiving bucket 5 and assist the receiving bucket 5 to move with the turntable 41.

[0038] A feed hopper 44 is mounted on the bracket 1. The feed hopper 44 is arranged in a vertical state. A feed port 442 is provided below the feed hopper 44. The feed port 442 is provided corresponding to the receiving barrel 5 clamped by the turntable 41. The horizontal cross-section of the feed port 442 is trapezoidal. The longer side of the trapezoid of the feed port 442 is arranged close to the axis of the turntable 41. The length of the longer side of the trapezoid of the feed port 442 is greater than the length of the receiving barrel 5. The feed port 442 can feed three receiving barrels 5 at the same time. A filter plate 441 is fixedly provided in the feed hopper 44. The filter plate 441 is located above the feed port 442 and is arranged in a horizontal state. A plurality of through holes are provided on the filter plate 441. The material can fall through the through holes. The filter plate 441 can intercept larger particles or impurities to prevent agglomerated material particles from passing through and entering the receiving barrel 5.

[0039] A material receiving box 45 is also fixedly connected to the bracket 1. The material receiving box 45 is located below the loading track 42. The upper end of the material receiving box 45 is opened, and the opening area of ​​the material receiving box 45 completely covers the loading track 42. The fallen materials can fall into the material receiving box 45 through the horizontal roller 421 rotating on the loading track 42, and the material receiving box 45 can collect the fallen materials. The bottom wall of the material receiving box 45 is inclined, and a material receiving port 451 is opened at the bottom wall of the material receiving box 45 close to the ground. After the materials fall onto the bottom wall of the material receiving box 45, the materials move toward the material receiving port 451 along the inclined surface of the material receiving box 45 under the action of gravity, which is convenient for the staff to collect the materials and then re-feed.

[0040] Guide plates 21 are fixedly connected to both sides of the feeding conveyor belt 2 along the width direction. The guide plates 21 are arranged close to the loading track 42. The two guide plates 21 located on both sides are arranged close to each other along the transmission direction of the upward section of the feeding conveyor belt 2. The existence of the guide plates 21 can effectively guide the moving track of the receiving bucket 5 on the feeding conveyor belt 2, so that it can accurately enter the loading track 42 and align with the placement groove 411 on the turntable 41. This helps to reduce the deviation and dislocation of the receiving bucket 5 during the movement process, and improve the accuracy and efficiency of the unloading operation.

[0041] A scraper 6 is fixedly connected to the bracket 1 at the connection position corresponding to the unloading conveyor belt 3 and the loading track 42. The scraper 6 is located above the loading track 42, and the scraper 6 is arranged horizontally along the axis direction of the horizontal roller 421. The scraper 6 is inclined from top to bottom away from the unloading conveyor belt 3. When the receiving barrel 5 passes under the scraper 6, the lower end of the scraper 6 can abut against the upper end surface of the receiving barrel 5, and the scraper 6 scrapes off the remaining material at the top position of the receiving barrel 5.

[0042] Fans 7 are symmetrically fixed on both sides of the unloading conveyor belt 3 along the upper edge of the bracket 1. The two fans 7 are arranged close to the scraper 6. The air outlets of the fans 7 are inclined downward toward the loading track 42. The fans 7 can blow the remaining materials away from the unloading conveyor belt 3, and the materials can smoothly fall into the material receiving box 45 for collection, thereby preventing the materials remaining on the loading track 42 from entering the unloading conveyor belt 3, thereby reducing the cleaning intensity of the staff.

[0043] A load-bearing plate is installed on the unloading conveyor belt 3 at a position away from the loading track 42, and the upper end of the load-bearing plate abuts against the lower side of the upward section of the unloading conveyor belt 3. A cylinder 81 is fixedly connected to the unloading conveyor belt 3 at the position corresponding to the load-bearing plate on the side of the loading conveyor belt 2 along the length direction. The cylinder 81 is arranged perpendicular to the length direction of the unloading conveyor belt 3, and the output end of the cylinder 81 can reciprocate along the width direction of the unloading conveyor belt 3. A unloading area 82 is fixedly arranged on the bracket 1 corresponding to the side of the unloading conveyor belt 3 away from the cylinder 81. The unloading area 82 is U-shaped and the opening is arranged toward the unloading conveyor belt 3. When the receiving barrel 5 passes through the load-bearing plate under the drive of the unloading conveyor belt 3, the load-bearing plate weighs the passing receiving barrel 5. When the weighing result is greater than the required weight, the cylinder 81 is started, and the receiving barrel 5 with an unqualified weighing result is pushed away from the unloading conveyor belt 3, and the unqualified receiving barrel 5 enters the unloading area 82 under the push of the cylinder 81.

[0044] The implementation principle of a continuous quantitative feeding conveying device in the embodiment of the present application is:

[0045] The staff puts the receiving bucket 5 on the feeding conveyor belt 2, and the receiving bucket 5 moves toward the turntable 41 driven by the feeding conveyor belt 2. When the receiving bucket 5 moves to a position close to the turntable 41, the receiving bucket 5 is sequentially clamped in the placement groove 411 of the turntable 41 under the guidance of the guide plate 21, and the receiving bucket 5 moves on the loading track 42 as the turntable 41 rotates. The lower hopper 44 continuously and stably releases the material, and the turntable 41 drives the receiving bucket 5 to move stably and uniformly. The receiving bucket 5 passes under the lowering port 442. Since the lowering port is trapezoidal in shape, and the trapezoidal lowering port can discharge materials to up to three receiving buckets 5 at the same time, the time for the receiving bucket 5 to pass through the lowering hopper is extended when the stroke of the receiving bucket 5 remains unchanged, ensuring that the receiving bucket 5 can receive enough materials. The material can be uniformly dropped into the receiving barrel 5 through the trapezoidal discharge port 442, and the material fills the receiving barrel 5. The trapezoidal design of the discharge hopper 44 and the discharge port 442, in conjunction with the turntable 41 controlling the rotation axis, can ensure that the material accurately falls into the receiving barrel 5, and quantitative discharge is achieved. After the discharge is completed, the receiving barrel 5 continues to rotate with the turntable 41 until it is separated from the turntable 41 and driven away from the turntable 41 by the discharge conveyor belt 3, and the discharge is completed, and a barrel of material in the receiving barrel 5 is added. The entire discharge process is realized by motor drive and mechanical transmission, without manual intervention, reducing labor intensity and improving the convenience of operation.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
