[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0038] like Figures 1 to 11As shown, a gearbox for collecting and pulling stems and picking ears includes a gearbox body 1001 for pulling stems and picking ears. Two vertically arranged stem pulling rollers 1003 are rotatably connected to the gearbox body 1001. The two stem pulling rollers 1003 are arranged on the left and the right. The gearbox body 1001 for pulling stems and picking ears is also rotatably connected to two vertically arranged feeding rollers 1002 located in front of the stem pulling rollers 1003. The two feeding rollers 1101 are arranged on the left and the right. The two stem pulling rollers 1003 are transmission-connected to each other, the two feeding rollers 1002 are transmission-connected to each other, and one of the stem pulling rollers 1003 is transmission-connected to one of the feeding rollers 1002. When in use, a stem pulling roller 901 is installed on the stem pulling roller shaft 1003, and an ear picking roller 801 is connected to the stem pulling roller 901. A feeding roller 1101 and a clamping sprocket 703 are connected to the feeding roller shaft 1002. The clamping sprocket 703 is used to drive the clamping chain 602. The clamping chain 602 is wound around the clamping sprocket 703, and the clamping sprocket 703 is located in front of the stem pulling roller 901. When in use, the two stem pulling rollers 901 rotate in opposite directions, and the two feeding rollers 1101 rotate in opposite directions. The clamping chain 602 drives the corn stalks to move backward. When the corn stalks reach the clamping sprocket 703, the stem pulling roller 901 and the ear picking roller 801 continue to pull the corn stalks and pick the corn ears. The clamping chain 602 continues to rotate to complete the delivery of the next corn stalk. The corn stalks will not bypass the stem pulling roller 901 under the drive of the clamping chain 602, thereby reducing the probability of the stem pulling roller 901 malfunctioning due to being entangled by broken leaves and improving production efficiency.

[0039] The two stalk pulling rollers 1003 and the two feeding rollers 1002 share a gear box, which has a compact structure, reliable transmission and reduces manufacturing cost.

[0040] One of the stem pulling roller shafts 1003 is equipped with a first stem pulling roller gear 1005 and a second stem pulling roller gear 1006, and the other stem pulling roller shaft 1003 is equipped with a third stem pulling roller gear 1007 meshing with the second stem pulling roller gear 1006. One of the feeding roller shafts 1002 is equipped with a second feeding roller gear 1009 and a first feeding roller gear 1008 meshing with the first stem pulling roller gear 1005, and the other feeding roller shaft 1002 is equipped with a third feeding roller gear 1010 meshing with the second feeding roller gear 1009. The stem pulling roller shaft 1003 equipped with the first stem pulling roller gear 1005 and the feeding roller shaft 1002 equipped with the first feeding roller gear 1008 are arranged diagonally. During use, power is transmitted to the first ear-picking roller 801, driving the first ear-picking roller 801 and the first stem-pulling roller shaft 1003 to rotate. The first stem-pulling roller shaft 1003 drives the second stem-pulling roller shaft 1003 to rotate via the second stem-pulling roller gear 1006 and the third stem-pulling roller gear 1007. The first stem-pulling roller shaft 1003 drives the first feeding roller shaft 1002 to rotate via the first stem-pulling roller gear 1005 and the first feeding roller gear 1008. The first feeding roller shaft 1002 drives the second feeding roller shaft 1002 to rotate via the second feeding roller gear 1009 and the third feeding roller gear 1010. This structure is compact and the transmission is reliable.

[0041] The first stalk pulling roller gear 1005 and the first feed roller gear 1008 are located in the lower inner portion of the stalk pulling and ear picking gear housing 1001, the second stalk pulling roller gear 1006 and the third stalk pulling roller gear 1007 are located in the upper inner portion of the stalk pulling and ear picking gear housing 1001, and the second feed roller gear 1009 and the third feed roller gear 1010 are located in the middle inner portion of the stalk pulling and ear picking gear housing 1001. During use, the gears in the stalk pulling and ear picking gear housing 1001 are arranged in three layers, reducing the risk of mutual interference and improving space utilization. This structure is compact and the transmission is reliable.

[0042] The height of the upper end of the feeding roller shaft 1002 is greater than the height of the upper end of the stalk pulling roller shaft 1003. When in use, the feeding roller shaft 1002 is used to mount the feeding roller 1101. Since the upper end of the feeding roller 1101 is suspended, the longer length of the feeding roller shaft 1002 is beneficial to improving the stability of the feeding roller 1101. The stalk pulling roller shaft 1003 is used to mount the stalk pulling roller 901 and the ear picking roller 801. Since the upper end of the ear picking roller 801 is suspended, the stalk pulling roller shaft 1003 can be shorter.

[0043] The stem pulling and ear picking gear box 1001 is equipped with a feeding roller sleeve 1004 that is sleeved on the feeding roller shaft 1002. The feeding roller shaft 1002 is rotatably connected to the upper end of the feeding roller sleeve 1004. When in use, the feeding roller 1101 is sleeved on the feeding roller shaft 1002, and the feeding roller sleeve 1004 can improve the stability of the feeding roller shaft 1002 and the feeding roller 1101.

[0044] The upper end of the stem pulling roller 1003 has a spline shaft structure, and the upper end of the feeding roller 1002 has a spline shaft structure. When in use, it is easy to install.

[0045] The upper end of the stem pulling and ear picking gear box 1001 is open, and the upper end of the stem pulling and ear picking gear box 1001 is detachably mounted with a stem pulling and ear picking gear box cover 1011, which facilitates the manufacture and installation of the stem pulling and ear picking gear box 1001.

[0046] The lower end of the stem pulling roller 1003 is rotatably connected to the bottom of the stem pulling and ear picking gear box 1001, and the stem pulling roller 1003 passes through the stem pulling and ear picking gear box cover 1011 and is rotatably connected to the stem pulling and ear picking gear box cover 1011. The lower end of the feeding roller 1002 is rotatably connected to the bottom of the stem pulling and ear picking gear box 1001, and the feeding roller 1002 passes through the stem pulling and ear picking gear box cover 1011 and is rotatably connected to the stem pulling and ear picking gear box cover 1011. This facilitates the manufacture and installation of the stem pulling and ear picking gear box 1001.

[0047] The distance between the center axes of the two pulling rollers 1003 is smaller than the distance between the center axes of the two feeding rollers 1002; the width of the gap between the two pulling rollers 901 is smaller than the width of the gap between the two feeding rollers 1101. This facilitates the transportation of corn stalks during use.

[0048] The shape of the gear box 1001 for pulling the stems and picking the ears is rectangular, and the four corners of the gear box 1001 are rounded, which is convenient for installing the gears.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
