Abstract
Description
Technical Field
[0001] This utility model belongs to the field of straw baling technology, and in particular relates to a round straw baler. Background Technology
[0002] Every autumn and winter, the burning of corn stalks and its resulting air pollution often become a major point of contention. The main uses of corn stalks are livestock feed, domestic fuel, or compost. However, due to the large area they cover, corn stalks are difficult to collect, leading to much of the stalks being burned directly in the fields. This causes air pollution. If the stalks are simply left in the fields to be shredded by machine, it will affect the planting of crops in the following season, negatively impacting crop growth. Therefore, baling and storing the stalks is necessary. However, existing round balers on the market contain a large amount of soil after baling and lack storage devices. When baling, the tractor must stop and wait for the bale to fall to the ground before continuing operation. The degree of stalk breakage within the bale makes it unsuitable as direct feed for cattle and sheep. Utility Model Content
[0003] In view of this, the present invention aims to propose a round bale baler to solve the problems of traditional balers, such as loose and ineffective baling, inadequate dust removal, and low efficiency caused by intermittent operation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A round bale baler includes a chassis, a hopper, a pickup, and a baling mechanism. The pickup is installed below the chassis, and its discharge end is connected to the feed end of the hopper. The hopper is installed above the chassis, and its discharge end is connected to the feed inlet of the baling mechanism. The baling mechanism includes a drive shaft, a connecting shaft, and a hopper-opening drive shaft. The first drive shaft sprocket of the drive shaft is connected to a power source. The second drive shaft sprocket of the drive shaft transmits power to the lower sprocket at the end of the hopper sequentially through single chains A, C, D, and E. The third drive shaft sprocket on the drive shaft transmits power sequentially through single chains F, G, and H. The power is delivered to the upper sprocket at the end of the cockpit. The fifth drive sprocket on the drive shaft introduces the power, which is then transmitted to the connecting shaft via the third double chain through the fourth drive sprocket on the drive shaft. The first connecting shaft sprocket on the connecting shaft receives the power and transmits it to the opening drive shaft through the second connecting shaft sprocket and the fourth double chain. The first opening drive shaft sprocket on the opening drive shaft receives the power and transmits it sequentially along single chains I, J, K, and L to the lower end of the opening sprocket through the second opening drive shaft sprocket. The third opening drive shaft sprocket on the opening drive shaft transmits the power sequentially along single chains M, N, and O to the upper end of the opening sprocket.
[0006] Furthermore, the right side of the bundling mechanism's seat compartment is equipped with a fourth tensioning wheel mechanism for adjusting the tension of the single chain C, and the left side is equipped with a first tensioning wheel mechanism, a second tensioning wheel mechanism, and a third tensioning wheel mechanism. The first tensioning wheel mechanism, the second tensioning wheel mechanism, and the third tensioning wheel mechanism are respectively used to adjust the second double chain, the third double chain, and the fourth double chain.
[0007] Furthermore, a drive shaft assembly and a gearbox assembly are mounted on the chassis, and the gearbox assembly is connected to the drive shaft assembly.
[0008] Furthermore, the driveshaft assembly includes a second driveshaft, a third driveshaft, a fourth driveshaft, a fifth driveshaft, and a sixth driveshaft.

The fifth gearbox transmits power to the sixth gearbox via the sixth driveshaft. The third gearbox transmits power to the fourth gearbox via the fourth driveshaft. The fourth and sixth gearboxes transmit power to the drive shaft via a first double chain and a second double chain, respectively.
[0009] Furthermore, the first gearbox transmits power to the hammer claw shaft, crushing shaft, and auger shaft in the pickup via the first drive shaft.
[0010] Furthermore, the cabin is equipped with a pressure roller shaft, which is engaged with a single chain C.
[0011] Furthermore, the hopper includes a tipping shaft, a discharge shaft, a conveyor belt, a middle layer of the hopper, and a lower layer of the hopper. The middle layer of the hopper is installed above the lower layer of the hopper, the tipping shaft is installed inside the middle layer of the hopper, and both the discharge shaft and the conveyor belt are installed inside the lower layer of the hopper. The discharge shaft is positioned above the conveyor belt.
[0012] Furthermore, an upper silo is installed above the middle silo, and a dust removal cap is installed inside the upper silo.
