Description

Technical Field

[0001] The invention relates to the technical field of rapid statistical analysis of silage corn biomass yield, and in particular to a method and a special tool for rapid statistical analysis of silage corn biomass yield. Background Art

[0002] Silage corn is the main forage for herbivorous livestock such as beef cattle and dairy cows, and occupies an important position in animal husbandry. The statistics of silage corn biomass include the harvesting of silage corn and the statistics of data. There is currently no unified and standardized standard for the statistics of silage corn biomass. The statistics of silage corn biomass are of great significance for scientific breeding. They can effectively improve the efficiency of yield measurement, reduce yield measurement errors, improve forage quality and ultimately improve the level of livestock breeding. In the process of statistical analysis of silage corn biomass, the harvesting of silage corn has always been done manually, which requires a lot of labor and has large errors. For the statistics of silage corn biomass, weighing the whole plant while harvesting the silage corn is an important step.

[0003] This patent is mainly used for production test and yield measurement of silage corn, and can also be used for yield measurement before harvest of silage corn planted on a large scale.

[0004] In the prior art, the main technical problems with statistics on the biomass yield of silage corn are: 1. There is no unified scientific statistical method for statistics on the biomass yield of silage corn, resulting in large differences in statistical indicators of the statistical data of the biomass yield of silage corn using different statistical methods, which cannot provide guidance for the quality and weight of scientifically raised silage corn feed. 2. The harvesting of silage corn has always been done manually, which requires a lot of labor and has large errors. At the same time, the weight of the entire silage corn plant cannot be accurately weighed, resulting in large statistical errors in the biomass yield of silage corn. Based on the above-mentioned defects in the prior art, the inventors have developed a method and special tools for quickly counting the biomass yield of silage corn, which can well solve the above-mentioned problems in the prior art. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and provide a method and special tool for quickly counting the biomass yield of silage corn. The invention is scientific and reasonable, with simple steps. The special tool for harvesting silage corn has an ingenious structure and a scientific and reasonable design. The present invention can solve the problem that there is no unified scientific statistical method for counting the biomass yield of silage corn, resulting in large differences in statistical indicators of the statistical data of the biomass yield of silage corn using different statistical methods, and cannot provide guidance for the quality and weight of silage corn feed for scientific breeding; at the same time, it also solves the problem that the harvesting of silage corn has always been done by manual operation, which requires a lot of labor and has large errors, and the weight of the entire silage corn plant cannot be accurately weighed.

[0006] The present invention provides a method for quickly calculating the biomass yield of silage corn:

[0007] Step 1: Choosing the harvesting time: The harvesting time of silage corn is selected from the late milky stage to the early waxy stage of the kernels;

[0008] Step 2: Calculate the plant and row spacing of silage corn: Select plots with consistent growth and no missing seedlings in the silage corn experimental field. 1. Calculate plant spacing: Select 51 silage corn plants along the silage corn planting row in the silage corn experimental field, measure the length between the 51 silage corn plants, and calculate the plant spacing. The calculation formula is: plant spacing m = length between 51 plants m / 50. Repeat three times and calculate the average value. 2. Calculate row spacing: Select 11 rows horizontally in the silage corn experimental field and use a tape measure to measure the length between the 11 rows of silage corn to calculate the plant spacing and row spacing. The calculation formula is: row spacing m = length between 11 rows m / 10. Repeat three times and calculate the average value.

[0009] Step 3. Calculate the silage corn planting density: Substitute the average plant spacing and average row spacing from step 2 into the silage corn planting density calculation formula to calculate the silage corn planting density value; the silage corn planting density calculation formula is: silage corn planting density (plants / mu) = 667 / (average plant spacing * average row spacing); where 667 square meters equals one mu;

[0010] Step 4. Calculation of the weight of a single silage corn plant: Using a tool specifically designed for harvesting silage corn, select 51 silage corn plants within a row in the silage corn experimental field. After harvesting, place the 51 plants in a collection drum. Weigh the drum using an electronic scale, then subtract the weight of the drum from the weight. Finally, divide the weight minus the drum by 51 to obtain the weight of a single silage corn plant. Repeat the above weighing three times and calculate the average value.

[0011] Step 5. Calculation of silage corn yield per mu: Calculation formula for silage corn yield per mu: Silage corn yield per mu (kg) = (weight of silage corn per plant * planting density of silage corn) * 0.85, where 0.85 is the conversion rate, which is a constant value; substitute the average value of silage corn planting density in step 3 and the average value of silage corn per plant weight in step 4 into the silage corn yield calculation formula to obtain the silage corn yield per mu.

[0013] The four universal wheels fixedly arranged at the lower part of the harvesting weighing platform are symmetrically arranged left to right and front to back.

[0014] The elastic limiting hoop includes a limiting hoop body, which is circular with an opening on the right side. The limiting baffles are fixedly arranged at the front and rear sides of the right opening of the limiting hoop body, and an arc-shaped transition surface is arranged at the right end of the limiting baffle.

[0015] The harvesting device includes a mounting plate, which is fixedly arranged in the middle position of the arc-shaped recess, a battery pack is fixedly arranged at the left end position of the mounting plate, a drive motor is fixedly arranged at the right position of the battery pack, and a drive gear is arranged on the upper part of the power output shaft of the drive motor; an upper harvesting knife is arranged on the upper part of the rotating shaft, and a lower harvesting knife is arranged at the lower position of the rotating shaft. The rotating shaft is arranged in the middle position of the right end of the mounting plate, the bearing seat is mounted on the rotating shaft, and the bearing seat is fixedly arranged in the middle position of the right end of the mounting plate; a driven gear is fixedly arranged on the rotating shaft, and the driven gear is located at the lower position of the upper harvesting knife.

[0016] The battery pack is fixedly connected to the drive motor via a connecting wire, and the battery pack is used to provide driving power to the drive motor.

[0017] The upper harvesting knife is 20 cm away from the ground, and the lower harvesting knife is 15 cm away from the ground.

[0018] The driving gear and the driven gear are arranged horizontally on the left and right sides, and are connected and transmitted via a transmission chain.

[0019] The use process of this special tool for harvesting silage corn is as follows: first, the operator turns on the drive motor of the harvesting device. During the high-speed rotation of the drive motor, the drive gear rotates on behalf of the drive gear, and the drive gear rotates on behalf of the driven gear through the transmission chain. Under the rotation of the driven gear, the rotating shaft rotates, and the rotation of the rotating shaft drives the upper harvesting knife and the lower harvesting knife to rotate at the same time. Then the operator holds the cart tightly with both hands and walks by rolling the universal wheels. At this time, the arc-shaped notch is aligned with a row of silage corn. The protruding parts on the front and rear sides of the arc-shaped notch separate the corn on both sides of the silage corn. As the cart continues to move forward, when the high-speed rotating upper harvesting knife and lower harvesting knife touch the silage corn stalks, the upper harvesting knife and lower harvesting knife instantly cut the silage corn. At this time, with the help of the cart's walking inertia, the whole silage corn that has been cut down is dumped towards the position of the collecting barrel. When the dumped whole corn is aligned with the silage corn on the collecting barrel, the upper harvesting knife and the lower harvesting knife will cut the silage corn instantly. When the stopper of the elastic stop hoop contacts (due to the weight of the corn stalks and ears), the stopper's elasticity instantly expands, allowing the entire corn plant to be gathered into the silage drum. After harvesting a row of silage corn, the silage drum is nearly full. The operator then hooks the weighing ropes on the front and rear sides of the silage drum to the hooks of the electronic scale. The operator then pulls the stopper lever out of the through hole, leaving the silage drum suspended. After the electronic scale weighs the corn, the weight of the silage drum is subtracted to record the weight of the entire silage corn plant. Finally, the operator removes the entire silage corn plant from the silage drum and proceeds to harvest the next row of silage corn.

[0020] In step 1, the harvest period of silage corn is selected between the late milky stage and the early waxy stage of the kernel. The main purpose of this is: on the one hand, the moisture content of silage corn is optimal during the late milky stage and the early waxy stage of the kernel, which is conducive to increasing the per-acre yield of corn silage; on the other hand, only when the silage corn has sufficient moisture content can the sour, sweet, wine koji aroma and corn stalk fragrance be produced during the silage fermentation process, achieving good palatability and high digestibility.

[0021] In step 2, the plant spacing and row spacing of silage corn are measured. The main purpose of doing this is: on the one hand, to provide accurate data for the calculation of silage corn planting density; on the other hand, to normalize and standardize the statistical indicators of silage corn biological yield.

[0022] In step three, the silage corn planting density is calculated; the main purpose of doing this is: on the one hand, to provide accurate data for the calculation of silage corn per mu yield, and on the other hand, to provide a unified method for the calculation of silage corn planting density.

[0023] In step four, the weight of a single silage corn plant is calculated; the main purpose of doing this is: on the one hand, to provide accurate data for the calculation of the per-acre yield of silage corn; on the other hand, to provide a new and scientific calculation method for the calculation of the weight of a single silage corn plant.

[0024] In step 5, the average value of the silage corn planting density in step 3 and the average value of the silage corn plant weight in step 4 are substituted into the silage corn yield per mu calculation formula to obtain the silage corn yield per mu. The main purposes of this are: on the one hand, by calculating the silage corn planting density and the silage corn plant weight, accurate calculation parameters are provided for the calculation of the silage corn yield per mu; on the other hand, a scientific and accurate statistical method is proposed for the calculation of the silage corn yield per mu.

[0025] The selection of the harvesting time in step 1 and the calculation in steps 2, 3, 4 and 5, on the one hand, provide a unified scientific statistical method for the rapid statistics of the biomass yield of silage corn, and provide scientific guidance for the quality and weight of silage corn feed in scientific breeding; on the other hand, improve the accuracy of the rapid statistics of the biomass yield of silage corn and reduce the error in the statistics of the biomass yield of silage corn.

[0026] A harvesting and weighing platform is located on the upper right side of the cart frame, with four universal wheels fixedly mounted below the platform. This arrangement allows the cart to roll through the silage field using the universal wheels as a rolling mechanism. Furthermore, the cart's inertia creates an inertial force (due to the weight of the harvested corn stalks) that causes the harvested corn stalks to tilt toward the cart.

[0027] The gantry is fixedly mounted on the upper portion of the harvesting and weighing platform, near the left side. The electronic scale is fixedly mounted at the bottom longitudinal center of the gantry, and a scale hook is provided at the bottom of the electronic scale. The main purpose of this arrangement is to, through the gantry, electronic scale, and scale hook, on the one hand, weigh the entire silage corn plant harvested in the harvesting drum, thereby obtaining weight statistics of the biomass yield of the silage corn. On the other hand, the electronic scale and scale hook, in conjunction with a weighing rope provided on the harvesting drum, can suspend the harvesting drum in the air for accurate weighing.

[0028] The collecting drum is placed obliquely in the middle of the gantry. The collecting drum is a cylindrical shape with a closed bottom and an open top, and an opening is provided on the right side of the collecting drum from top to bottom. The main purpose of this arrangement is: on the one hand, to prevent the whole silage corn from falling from the bottom of the collecting drum onto the harvesting and weighing platform after harvesting, causing the whole silage corn to be in disarray; on the other hand, to allow the whole silage corn that has been peeled and fallen to enter the collecting drum from the opening provided on the right side of the collecting drum from top to bottom, thereby playing the role of organizing the whole silage corn after harvesting; on the other hand, the obliquely placed collecting drum can automatically organize the whole silage corn into the collecting drum by utilizing the oblique angle, making it convenient to weigh and remove the whole silage corn, thereby improving the efficiency of silage corn harvesting.

[0029] The through holes are fixedly arranged on the front and rear sides of the gantry near the lower position, and the limiting pull rods are inserted into the through holes correspondingly arranged on the front and rear sides of the gantry near the lower position, and the limiting pull rods pass through the left side of the collecting cylinder to limit and fix the collecting cylinder; the main purpose of such a setting is: through the pulling action of the limiting pull rod, on the one hand, the collecting cylinder is limited in an inclined position; on the other hand, the collecting cylinder can be laid down, so as to realize the role of weighing the whole silage corn in the collecting cylinder, and provide weight data for the biological yield statistics of silage corn.

[0030] The elastic limiting hoop is fixedly wrapped around the outer wall of the collecting and sorting cylinder. The elastic limiting hoop is a circle with an opening on the right side. Two elastic limiting hoops are symmetrically arranged on the outer wall of the collecting and sorting cylinder, one on the upper side and the other on the lower side. The main purpose of such arrangement is: through the elastic action of the elastic limiting hoop, on the one hand, it can guide and sort the whole silage corn that has been peeled and tilted; on the other hand, it can prevent the silage corn sorted in the collecting and sorting cylinder after harvesting from overflowing from the collecting and sorting cylinder, thereby ensuring the orderliness of the whole silage corn.

[0031] The arc-shaped notch is fixedly positioned in the center of the right side of the harvester weighing platform. This arrangement aims to separate the silage corn rows by utilizing the indentation in the arc-shaped notch and the protrusions on both sides. Furthermore, it provides space for the mounting plate of the harvester.

[0032] The weighing rope is fixedly mounted between the front and rear sides of the storage drum and is used to securely connect to the hook of the electronic scale. The main purpose of this arrangement is to utilize the cooperation of the weighing rope and the hook to connect the storage drum and the electronic scale as a whole, thus providing conditions for weighing the storage drum while suspended.

[0033] The elastic limiting hoop includes a limiting hoop body, which is circular and open on the right side. Limiting blocks are fixedly disposed at positions in front and behind the right opening of the limiting hoop body. The right end of the limiting block is provided with an arcuate transition surface. The main purpose of this arrangement is to, on the one hand, prevent the silage corn stored in the collection drum after harvesting from overflowing from the collection drum, thereby ensuring the orderliness of the entire silage corn plant. On the other hand, it prevents the thorny points of the limiting block from scratching the entire silage corn plant, thereby ensuring the integrity of the entire silage corn plant and improving the quality of the silage corn feed.

[0034] The driving motor is fixedly arranged at the right side of the battery pack, and a driving gear is arranged on the upper part of the power output shaft of the driving motor; an upper harvesting knife is arranged on the upper part of the rotating shaft, and a lower harvesting knife is arranged at the lower part of the rotating shaft. The rotating shaft is arranged at the middle position of the right end of the mounting plate, and the bearing seat is mounted on the rotating shaft, and the bearing seat is fixedly arranged at the middle position of the right end of the mounting plate; the driven gear is fixedly arranged on the rotating shaft, and the driven gear is located at the lower part of the upper harvesting knife. The main purpose of such arrangement is: using the battery pack as power to provide electricity to the driving motor, and under the cooperation of the driving motor, the driving gear and the driven gear, the upper harvesting knife and the lower harvesting knife rotate simultaneously; on the one hand, it plays the role of rotary cutting and harvesting the whole silage corn, and on the other hand, it leaves the stubble of the whole silage corn, while improving the passability of the cart, and returning the root stubble of the whole silage corn with low nutritional value to the field.

[0035] The coordination of all the connecting structures in the special tool for harvesting silage corn of the present invention and the technical effects achieved by the connecting structures are interrelated and inseparable in the entire protection scheme; and should be viewed as a whole technical scheme.

[0036] The present invention has the following beneficial effects: 1. It standardizes the statistical method for silage corn biomass production, providing scientific guidance for the quality and weight of silage corn feed for scientific farming. 2. It improves silage corn harvesting efficiency and reduces the labor intensity of harvesting silage corn. Furthermore, it can weigh the entire harvested silage corn plant, reducing the error in calculating silage corn biomass production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention will be further described below with reference to specific examples. These examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0041] The present invention provides a method for quickly calculating the biomass yield of silage corn:

[0042] Step 1: Choosing the harvesting time: The harvesting time of silage corn is selected from the late milky stage to the early waxy stage of the kernels;

[0043] Step 2: Calculate the plant and row spacing of silage corn: Select plots with consistent growth and no missing seedlings in the silage corn experimental field. 1. Calculate plant spacing: Select 51 silage corn plants along the silage corn planting row in the silage corn experimental field, measure the length between the 51 silage corn plants, and calculate the plant spacing. The calculation formula is: plant spacing m = length between 51 plants m / 50. Repeat three times and calculate the average value. 2. Calculate row spacing: Select 11 rows horizontally in the silage corn experimental field and use a tape measure to measure the length between the 11 rows of silage corn to calculate the plant spacing and row spacing. The calculation formula is: row spacing m = length between 11 rows m / 10. Repeat three times and calculate the average value.

[0044] Step 3. Calculate the silage corn planting density: Substitute the average plant spacing and average row spacing from step 2 into the silage corn planting density calculation formula to calculate the silage corn planting density value; the silage corn planting density calculation formula is: silage corn planting density (plants / mu) = 667 / (average plant spacing * average row spacing); where 667 square meters equals one mu;

[0045] Step 4. Calculation of the weight of a single silage corn plant: Using a tool specifically designed for harvesting silage corn, select 51 silage corn plants within a row in the silage corn experimental field. After harvesting, place the 51 plants in a collection drum. Weigh the drum using an electronic scale, then subtract the weight of the drum from the weight. Finally, divide the weight minus the drum by 51 to obtain the weight of a single silage corn plant. Repeat the above weighing three times and calculate the average value.

[0046] Step 5. Calculation of silage corn yield per mu: Calculation formula for silage corn yield per mu: Silage corn yield per mu (kg) = (weight of silage corn per plant * planting density of silage corn) * 0.85, where 0.85 is the conversion rate; substitute the average value of silage corn planting density in step 3 and the average value of silage corn per plant weight in step 4 into the silage corn yield calculation formula to obtain the silage corn yield per mu.

[0048] The four universal wheels 103 fixedly arranged at the lower part of the harvesting weighing platform 102 are symmetrically arranged left to right and front to back.

[0049] The elastic limiting hoop 9 includes a limiting hoop body 91, which is circular with an opening on the right side. The limiting baffle 92 is fixedly arranged at the front and rear sides of the right opening of the limiting hoop body 91, and an arc-shaped transition surface 93 is provided at the right end of the limiting baffle 92.

[0050] The harvesting device 11 includes a mounting plate 111, which is fixedly arranged in the middle position of the arc-shaped recess 10, a battery pack 112 is fixedly arranged at the left end position of the mounting plate 111, a drive motor 113 is fixedly arranged at the right position of the battery pack 112, and a drive gear 114 is arranged on the upper part of the power output shaft of the drive motor 113; an upper harvesting knife 116 is arranged on the upper part of the rotating shaft 115, and a lower harvesting knife 117 is arranged at the lower part of the rotating shaft 115, the rotating shaft 115 is arranged in the middle position of the right end of the mounting plate 111, and a bearing seat 118 is mounted on the rotating shaft 115, and the bearing seat 118 is fixedly arranged in the middle position of the right end of the mounting plate 111; a driven gear 119 is fixedly arranged on the rotating shaft 115, and the driven gear 119 is located at the lower position of the upper harvesting knife 116.

[0051] The battery pack 112 is fixedly connected to the drive motor 113 via a connecting wire, and the battery pack 112 is used to provide driving power to the drive motor 113.

[0053] The driving gear 114 and the driven gear 119 are arranged horizontally on the left and right sides, and the driving gear 114 and the driven gear 119 are connected to each other through a transmission chain.

[0054] The use process of this special tool for harvesting silage corn is as follows: first, the operator turns on the drive motor 113 of the harvesting device 11. During the high-speed rotation of the drive motor 113, the drive gear 114 is driven to rotate. The drive gear 114 drives the driven gear 119 to rotate through the transmission chain.

After harvesting a row of silage corn, the collection drum 5 is almost full. At this time, the operator hangs the weighing ropes 12 on the front and rear sides of the collection drum 5 to the scale hook 4 of the electronic scale 3. The operator then grasps the tension handle 8 and pulls the limit pull rod 7 out of the through hole 6. The collection drum 5 is suspended in the air. After the electronic scale 3 completes the weighing, the weight of the whole corn plant is subtracted from the weight of the collection drum 5 to record the weight of the whole corn silage plant. Finally, the operator removes the whole corn silage plant from the collection drum 5 and proceeds to harvest the next row of silage corn.
