Technical Field

[0001] The utility model relates to the technical field of granary upper boxes, in particular to a granary upper box for a corn harvester. Background Art

[0002] Combine harvesters are common agricultural machinery. The harvesting procedure of a harvester is as follows: the harvesting platform cuts down the rice ears, and the rice ears with rice stalks are transported to the threshing chamber through the lifting trough. The granary in the harvester is a mechanism for collecting grains.

[0003] Although the existing upper box of the harvester can cover and collect corn kernels during use, the existing upper box is not provided with a mechanism for weighing the collected corn kernels. As a result, after each harvest, the user needs to weigh the corn kernels bag by bag to achieve the effect of counting corn yields, which reduces the practicality of the existing upper box. For this reason, we propose a corn harvester granary upper box. Summary of the Invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 A corn harvester grain bin upper box body includes a main body 1, the outer wall of the main body 1 is provided with a display panel 2, the inner wall of the main body 1 is provided with a mounting groove 12, the inner wall of the mounting groove 12 is fixedly equipped with a straight rod 10, the outer wall of the straight rod 10 is sleeved with a weighing spring 11, the top of the weighing spring 11 is in contact with a receiving hopper 3, the bottom of the receiving hopper 3 is respectively fixedly equipped with a counter 4 and a signal transmitter 6, the outer wall of the receiving hopper 3 is fixedly equipped with a processor 5, the bottom end of the receiving hopper 3 is provided with a groove 14, the inner wall of the groove 14 is fixedly equipped with a motor 8, the output shaft of the motor 8 is fixedly equipped with a baffle 9, and the bottom of the inner wall of the mounting groove 12 is respectively fixedly equipped with a signal sensor 7 and a controller 13.

[0021] In the above structure, through the arrangement of the main body 1, display panel 2, hopper 3, straight rod 10, weighing spring 11, controller 13, motor 8, and baffle 9, when the harvester harvests corn, the hopper 3 in the box body will first collect the corn kernels, and as the corn kernels continue to accumulate, the hopper 3 gradually drops and compresses the weighing spring 11, so that the signal sensor 7, weighing spring 11 and counter 4 and controller 13 count the weight of the corn kernels to achieve the weighing effect. At the same time, after reaching the load limit of the hopper 3, the controller 13 will automatically control the motor 8 to discharge the corn kernels, and the counter 4 will count the number of times the motor 8 operates and display the specific value on the display panel 2, thereby facilitating the user to count the corn yield, thereby improving the practicality and intelligence of the upper box body.

[0022] In a preferred embodiment, a sliding hole is formed on the outer wall of the hopper 3 , and the inner wall of the sliding hole is slidably connected to the outer wall of the straight rod 10 , and the outer wall of the hopper 3 is slidably connected to the inner wall of the mounting groove 12 .

[0023] In the above structure, the sliding hole structure is provided so that the receiving hopper 3 continuously descends due to the change in weight after receiving the corn kernels, thereby achieving the effect of weighing the corn kernels and ensuring the normal operation of the upper box.

[0024] In a preferred embodiment: the top of the baffle 9 fits tightly against the bottom of the receiving hopper 3, the top of the receiving hopper 3 is provided with an electrode sheet 1, and the top of the inner wall of the main body 1 is provided with an electrode sheet 2, both the electrode sheet 1 and the electrode sheet 2 are electrically connected to the controller 13, and when the electrode sheet 1 contacts the electrode sheet 2, the top of the baffle 9 fits tightly against the bottom of the receiving hopper 3.

[0025] In the above structure, through the arrangement of electrode sheet one and electrode sheet two, when the receiving hopper 3 has released all the corn kernels, electrode sheet one and electrode sheet two will come into contact, thereby cooperating with the controller 13 to send an electrical signal to allow the motor 8 to drive the baffle 9 to reset and seal the receiving hopper 3, thereby ensuring that the corn kernels that have just entered the receiving hopper 3 will not leak during the subsequent weighing process, thereby ensuring the weighing accuracy of the harvested corn kernels by the upper box body.

[0026] In a preferred embodiment: the controller 13 is electrically connected to the display panel 2, the counter 4, the processor 5, the signal transmitter 6, the signal sensor 7, and the motor 8 respectively, the weighing spring 11 is electrically connected to the processor 5 and the display panel 2 respectively, and the counter 4 is electrically connected to the display panel 2 and the processor 5 respectively.

[0027] In the above structure, through the display panel 2, counter 4, processor 5, signal transmitter 6, signal sensor 7, and motor 8 structures, when the hopper 3 is in the weighing process, the weighing spring 11 and the signal sensor 7 will continue to approach each other due to the continuous decline. The time point when the two are in contact is used in conjunction with the controller 13 to send a signal to the motor 8, thereby ensuring that the hopper 3 can release the corn kernels in time, thereby improving the automation and intelligence of the upper box.

[0028] In a preferred embodiment, the distance between the baffle 9 and the weighing spring 11 is greater than the diameter of the baffle 9 , and the baffle 9 is made of stainless steel.

[0029] In the above structure, stainless steel has the characteristics of hardness and wear resistance, which can effectively reduce the erosion of dust and moisture on corn crops on the baffle 9, thereby extending the service life of the baffle 9. At the same time, stainless steel is also easy to process and is convenient to obtain and use.

[0030] In a preferred embodiment, the number of the weighing springs 11 is two, and the two weighing springs 11 are symmetrically distributed along the inner wall of the installation groove 12 .

[0031] In the above structure, the two weighing springs 11 are provided so that the receiving hopper 3 can be fully limited during operation, thereby ensuring that the receiving hopper 3 will not tilt or even shift in position during the lifting process, thereby improving the stability of the receiving hopper 3 during operation.

[0032] Working principle: First, after the user has installed the upper box body, the user can use the harvester to make the corn kernels enter the receiving hopper 3. At this time, the top of the baffle 9 fits with the bottom of the receiving hopper 3, so that the corn kernels accumulate in the receiving hopper 3. Then the weight of the receiving hopper 3 continues to increase, so that the weighing spring 11 continues to approach the signal sensor 7, and cooperates with the counter 4 and the processor 5 to weigh the corn kernels in the receiving hopper 3. When the signal sensor 7 and the weighing spring 11 overlap, the controller 13 automatically controls the motor 8 to release the corn kernels until the release is completed and the electrode sheet 1 and the electrode sheet 2 are re-contacted, so as to reset the baffle 9, thereby improving the automation of the upper box body. After the weighing is completed, the counter 4 will display the number of times the receiving hopper 3 drops and the corn kernel weight data on the display panel 2, so that the user can calculate the weight of the corn kernels, and then it is convenient for the user to count the corn yield, thereby improving the practicality of the upper box body.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
