Description

I. Technical Field

[0001] This invention relates to agricultural and livestock feed processing technology, specifically to a corn stalk crushing and shredding machine. II. Background Technology

[0002] Corn stalk roughage presents challenges such as difficulty in chewing, poor palatability, significant feed waste, and low digestibility. Crushing and shredding corn stalks is a crucial step in the comprehensive utilization of this resource. This process breaks down the stalks into soft, fibrous strands, fully exposing the pith and inner fibers, making it easier for ruminant livestock to absorb nutrients. Therefore, efficient corn stalk crushing and shredding machines are of great significance for fully utilizing agricultural corn stalk resources, promoting agricultural mechanization, and ensuring the sustainable development of animal husbandry. III. Summary of the Invention

[0003] The purpose of this invention is to develop a corn stalk crushing and shredding machine. Corn stalk crushing and shredding is a key step in the comprehensive utilization of straw resources. After being crushed and shredded, corn stalks become high-quality roughage for ruminant livestock and have high utilization value.

[0004] The technical solution of this invention:

[0005] A corn stalk crushing and shredding machine processes corn stalks into soft, appropriately sized filaments, which can then be used as roughage for ruminant livestock. The machine mainly consists of a conveying mechanism, a feeding and flattening mechanism, a chopping mechanism, a crushing and shredding transmission system, a discharge port, a frame, a motor, and a conveying, feeding, chopping, and transmission system. The motor is connected to the conveying mechanism, feeding and flattening mechanism, chopping mechanism, and crushing and shredding mechanism via the conveying, feeding, chopping, and transmission systems.

[0006] The motor's output shaft is connected to the motor's output pulley, which in turn is connected to the chaff cutter shaft pulley via a transmission belt. The chaff cutter shaft of the chaff cutter mechanism is driven by a large gear on the chaff cutter shaft meshing with the input gear of the lower feed flattening roller. The input gear of the lower feed flattening roller is connected to one end of the lower feed flattening roller shaft. Simultaneously, the small gear on the chaff cutter shaft meshes with either the large gear on the shredding shaft or the small gear on the shredding shaft. A shredding speed adjustment handle is installed between the large gear and the small gear on the shredding shaft. The large gear and the small gear on the shredding shaft slide axially together, completing the meshing of the small gear on the chaff cutter shaft with the large gear on the shredding shaft or the meshing of the large gear on the chaff cutter shaft with the shredding shaft. The small gear meshing transmission is switched, and the kneading and cutting shaft drives the crushing and kneading rotor to rotate. At the same time, the other end of the lower feeding flattening roller shaft is connected to the lower feeding flattening roller transmission output gear. The lower feeding flattening roller transmission output gear meshes with the upper feeding flattening roller transmission gear. The lower feeding flattening roller shaft sprocket is installed on the outermost side of the lower feeding flattening roller shaft, and is connected to the power input sprocket of the conveyor chain plate drive shaft through the transmission chain. The power input sprocket of the conveyor chain plate drive shaft is located at one end of the conveyor chain plate drive shaft, and the other end of the conveyor chain plate drive shaft is equipped with the power output sprocket of the conveyor chain plate drive shaft. The power output sprocket of the conveyor chain plate drive shaft and the conveyor chain plate movable shaft sprocket installed on the movable shaft of the conveyor belt are connected and driven by the conveyor chain plate.

Detailed Implementation

[0012] A corn stalk crushing and shredding machine processes corn stalks into soft, long filaments, which can then be used as roughage for ruminant livestock. The machine mainly consists of a conveying mechanism (1), a feeding and flattening mechanism (2), a chopping mechanism (3), a crushing and shredding transmission system (4), a crushing and shredding mechanism (5), a discharge port (6), a frame (7), a motor (8), and a conveying, feeding, chopping, and cutting transmission system (9). The motor (8) is connected to the conveying mechanism (1), the feeding and flattening mechanism (2), the chopping mechanism (3), and the crushing and shredding mechanism (5) through the conveying, feeding, chopping, and cutting transmission system (9) and the crushing and shredding transmission system (4) to transmit power. All mechanisms work together to ensure the overall functionality of the machine.

[0013] The power output shaft (31) of the electric motor (8) is connected to the output pulley (32) of the electric motor, and is connected to the chaff cutter shaft pulley (29) through the transmission belt (33) to realize the operation function of the chaff cutter mechanism. The chaff cutter shaft (14) of the chaff cutter mechanism is meshed with the input gear (16) of the lower feed flattening roller through the large gear (15) of the chaff cutter shaft. The input gear (16) of the lower feed flattening roller is connected to one end of the lower feed flattening roller shaft (17). At the same time, the small gear (13) of the chaff cutter shaft is connected to the large gear (11) of the shredding shaft. Alternatively, the large gear (15) of the chaff cutting shaft can mesh with the small gear (10) of the kneading shaft for transmission. A kneading speed conversion handle (34) is placed between the large gear (11) and the small gear (10) of the kneading shaft. The large gear (11) and the small gear (10) of the kneading shaft, which are arranged on the kneading shaft (12), slide axially together to complete the conversion between the meshing of the small gear (13) of the chaff cutting shaft and the large gear (11) of the kneading shaft or the meshing of the large gear (15) of the chaff cutting shaft and the small gear (10) of the kneading shaft for transmission. The kneading shaft (12) drives the crushing and kneading rotor to rotate, thereby setting the rotation speed of the crushing and kneading rotor according to the material characteristics and completing the operation function of the crushing and kneading mechanism (5). At the same time, the other end of the lower feeding flattening roller shaft (17) is connected to the lower feeding flattening roller drive output gear (28). The lower feeding flattening roller drive output gear (28) meshes with the upper feeding flattening roller drive gear (25) to realize the operation function of the feeding flattening mechanism (2). The lower feeding flattening roller shaft sprocket is installed on the outermost side of the lower feeding flattening roller shaft (17). (27) is connected to the power input sprocket (24) of the drive shaft of the conveyor chain plate through the transmission chain (26). The power input sprocket (24) of the drive shaft of the conveyor chain plate is placed at one end of the drive shaft (19) of the conveyor chain plate. The other end of the drive shaft (19) of the conveyor chain plate is equipped with the power output sprocket (20) of the drive shaft of the conveyor chain plate. The power output sprocket (20) of the drive shaft of the conveyor chain plate and the drive shaft sprocket (23) of the conveyor chain plate installed on the movable shaft (22) of the conveyor belt are connected by the conveyor chain plate (21) to jointly complete the feeding operation.

[0014] During operation, the straw is placed on the conveyor chain plate (21) of the conveyor mechanism (1). As the chain plate moves forward, it is conveyed to the feeding and flattening stage for operation. The upper and lower feeding and flattening rollers of the feeding and flattening mechanism (2) grab the corn straw and flatten it by breaking the joints. Then it enters the chopping mechanism (3) where the rotating cutter cuts the straw into the feed length required by the livestock. After that, it enters the crushing and shredding stage. The corn straw segments are subjected to the combined effects of hammering, shearing, collision, kneading and squeezing by the high-speed rotating and interlocking kneading and cutting blades. According to the material characteristics of the corn straw at that time, the kneading and cutting speed change handle (34) is operated to set the rotation speed of the crushing and shredding rotor, so that the corn straw with coarse and hard stems is kneaded into soft filaments with a length not exceeding 5cm. Then, the straw is subjected to the airflow of the high-speed rotating kneading and cutting blades, and the processed straw feed is thrown out through the discharge port (6), thus completing the crushing and shredding operation of the corn straw.
