Description

Technical Field

[0001] This utility model relates to the field of silage corn production technology, and in particular to a device for rapid determination of fresh yield and ear quality of silage corn. Background Technology

[0002] Silage corn is a major feed source for dairy and beef cattle, providing over 80% of their feed needs. Its fresh yield and quality directly affect livestock nutrition and production performance; therefore, accurately measuring silage corn yield and quality is crucial for optimizing livestock management and improving economic efficiency.

[0003] Currently, the determination of whole-plant fresh yield and ear-to-dryness ratio in silage corn mainly relies on manual whole-plant harvesting. The corn ears are then manually separated and weighed individually. The proportion of each ear to the total fresh yield of the silage corn is then calculated to determine its quality. However, this traditional method has the following significant problems:

[0004] The entire process requires a lot of manual labor, including harvesting, breaking off ears of fruit, weighing, and counting, which is time-consuming, labor-intensive, and inefficient.

[0005] Because it relies on manual operation, it is easily affected by human factors, such as improper operation and fatigue, which can lead to inconsistent data collection and large errors in measurement results. Utility Model Content

[0006] The purpose of this invention is to provide a device for rapid determination of fresh yield and ear quality of silage corn, which can avoid the need for a large amount of manual intervention in the whole process, including harvesting, breaking off ears, weighing and counting, which is time-consuming, labor-intensive and inefficient.

[0007] This utility model provides a device for rapid determination of fresh yield and ear quality of silage corn, including a tracked machine. A corn peeling mechanism is installed at the front end of the tracked machine, and a straw crushing mechanism is installed at the front end of the corn peeling mechanism. The straw crushing mechanism crushes the whole silage corn straw, and the corn ears enter the corn peeling mechanism for peeling. The crushed straw enters a loading box set on one side of the tracked machine for weighing, and the peeled corn ears enter a corn box set at the top of the tracked machine for weighing. A yield area statistics device is installed in the driver's cab of the tracked machine, and a GPS receiver is installed at the top of the tracked machine.

[0017] This utility model provides a rapid determination device for fresh yield and ear quality of silage corn, which, compared with the prior art:

[0018] 1. This utility model uses a pair of rotating conveyor rods to break and convey corn stalks downwards, allowing the crushing blades to crush the stalks. The crushed stalks are then conveyed by conveyor belt one to a loading bin for weighing. Weight measurement is performed simultaneously during the crushing process, ensuring timely and accurate data collection and reducing manual intervention. Meanwhile, a baffle prevents corn ears from entering the hopper, where a peeling screw peels the ears. Conveyor belt two then conveys the peeled corn to a corn bin for weighing. The ears are collected and weighed separately, providing a precise data basis for calculating the ear-to-dryness ratio, which helps to more accurately assess the quality of silage corn. A yield area statistics device is used to calculate the yield area. The device integrates multiple functions such as crushing, weighing, ear processing, and area statistics, reducing equipment changeover time and improving overall work efficiency.

[0019] 2. This utility model uses a movable seat that is slidably installed on the upper end of the feeding box, so that the movable plate can move with the push plate. Combined with the retraction of the cylinder, the push plate can move up and down. The push plate can be used to push the straw in the feeding box, which not only avoids the accumulation of the feeding box inlet, but also facilitates the discharge of the feeding box.

[0031] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please refer to Figures 1-8 This utility model provides a device for rapid determination of fresh yield and ear quality of silage corn, including a tracked machine 1. The front end of the tracked machine 1 is equipped with a corn peeling mechanism, wherein the corn peeling mechanism includes a hopper 2 installed at the front end of the tracked machine 1. A peeling spiral 3 is rotatably arranged in the hopper 2. When the peeling spiral 3 is driven by a motor, the peeling spiral 3 rotates to peel the corn ears with husks that have entered the hopper 2.

[0033] In addition, a conveying shell 20 is connected to the inlet end of the corn box 22. The outlet end of the conveying shell 20 extends to the discharge port 4 at the lower end of the hopper 2. A second conveyor belt 21 is installed inside the conveying shell 20. The peeled ears of corn fall from the discharge port 4 onto the second conveyor belt 21. The second conveyor belt 21 transports the ears of corn upwards, so that the ears of corn enter the corn box 22. Since a second weighing device 23 is installed inside the corn box 22, the second weighing device 23 weighs the ears of corn.

[0034] Furthermore, in order to automatically crush the corn stalks, a stalk crushing mechanism is installed at the front end of the corn peeling mechanism. The whole corn silage stalks are crushed by the stalk crushing mechanism, and the corn ears enter the corn peeling mechanism for peeling. The crushed stalks are then weighed in the loading box 13 set on one side of the crawler 1.

[0035] Specifically, the straw crushing mechanism includes a mounting base 5 installed at the front end of the hopper 2. A pair of conveying rods 6 are rotatably installed inside the mounting base 5. Gears 9 are connected to the shafts of the pair of conveying rods 6, and the two gears 9 mesh with each other. At the same time, blades 7 are installed on the pair of conveying rods 6. When one of the gears 9 is driven by a motor, the rotation of the two gears 9 drives the two conveying rods 6 to rotate. As the crawler 1 moves, the whole corn plant enters between the two conveying rods 6. The rotation of the conveying rods 6 breaks the straw, and the rotation of the conveying rods 6 causes the straw to be conveyed downward.

[0036] At this time, baffles 8 are symmetrically arranged on the mounting base 5 at the upper end of the conveyor rod 6. There is a gap between the two baffles 8. The straw is located within the gap between the two baffles 8. As the straw moves downward continuously, the ears of fruit are blocked by the baffles 8, causing the ears of fruit to remain on the baffles 8.

[0037] A pair of conveyor wheels 10 are rotatably mounted on the upper end of the mounting base 5. The conveyor wheels 10 are driven by a motor. After the ears of fruit enter between the two conveyor wheels 10, the ears of fruit are conveyed to the hopper 2 for peeling by the rotation of the conveyor wheels 10.

[0038] Since the lower end of the mounting base 5 is equipped with a shredder 11, the shredder 11 is driven by a motor, and the straw that moves downward continuously is shredded by the rotating shredder 11. The size of the shredded straw is 5-8cm.

[0039] Furthermore, a conveyor belt 12 is installed on the track machine 1 located below the crusher blade 11. The conveyor belt 12 receives the crushed straw, and a loading box 13 is installed on one side of the track machine 1. The loading box 13 is located below the discharge end of the conveyor belt 12. The conveyor belt 12 can transport the crushed straw into the loading box 13, and the straw can be weighed by the weighing device 14 installed at the bottom of the loading box 13.

[0040] Considering that straw is prone to accumulate at the feed inlet of the feeding box 13, a sliding groove 15 is provided at the upper end of the feeding box 13. A lead screw 16 is rotatably installed in the sliding groove 15. The lead screw 16 is threadedly connected to the moving seat 17. A cylinder 18 is installed at the upper end of the moving seat 17. A lever 19 is connected to the piston end of the cylinder 18. The contraction of the cylinder 18 drives the lever 19 to move up and down, thereby adjusting the lever 19 to a suitable height. Combined with the rotation of the lead screw 16, the moving seat 17 slides automatically, causing the lever 19 to push the straw to the other end of the feeding box 13, which also facilitates the unloading of the straw.

[0041] The dry weight ratio of silage corn ears is calculated as follows: (Fresh weight of harvested ears / Fresh weight of whole silage corn plant) * 100%. This can be calculated based on the data obtained from the weighing process described above.

[0042] To calculate the harvested area, a harvested area statistics device 25 is installed in the cab of the tracked machine 1. A GPS receiver 24 is installed on the top of the tracked machine 1. The GPS receiver 24 receives satellite signals in real time, accurately records the travel path of the tracked machine 1, and transmits the data to the harvested area statistics device 25. The harvested area statistics device 25 calculates the actual harvested area based on the coordinate points provided by the GPS using a built-in algorithm. Typically, polygon approximation or trajectory integration methods are used to calculate the area to ensure accuracy. The harvested area statistics device 25 is existing technology; suitable equipment can be selected, which will not be described in detail here.

[0043] Both weighing component 14 and weighing component 23 can preferably use strain gauge load cells. By attaching strain gauges to the corn box 22 and the loading box 13, when the weight in the loading box 13 changes, it causes a slight deformation of the metal parts, and the strain gauges generate a change in resistance, which is then converted into an electrical signal output.

[0044] In summary, the working principle of the rapid determination device for fresh yield and ear quality of silage corn in this embodiment of the present invention is as follows: the corn stalks are broken and conveyed downward by the rotation of a pair of conveyor rods 6, so that the crushing blade 11 crushes the stalks. The crushed stalks are conveyed to the loading box 13 by the first conveyor belt 12 for weighing. At the same time, the corn ears are blocked by the baffle 8 and enter the hopper 2. The corn ears are peeled by the rotation of the peeling spiral 3. Then, the peeled corn is conveyed to the corn box 22 by the second conveyor belt 21 for weighing.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
