Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and in particular relates to a device and method for dust removal and baling of forage. Background Art

[0002] Currently, existing balers can compress straw, wheat straw, bean stalks, stalks, and forage grass into bales. According to Chinese Patent No. CN110539936A, a straw compression device comprises upper and lower belt rollers and a roller conveyor. After the compressed straw is pushed out of a hopper by a thrust hydraulic cylinder, it enters a roller conveyor in a baling chamber. The roller conveyor's movement causes the straw blocks to collide with a baling belt. The baling belt, thrust by the straw blocks, is pulled out and wrapped around the straw blocks. When the straw blocks reach a designated position and hit a baffle, the roller conveyor stops, and a hot melt and cutting device activates to fuse and cut the upper and lower baling belts, completing the baling of a set of straw blocks. However, this operation generates dust. According to Chinese Patent No. CN110539936A, a straw compression device uses rollers to cause straw blocks to collide with a baling belt. The baling belt is pulled out and wrapped around the straw block under the thrust of the straw block. When the straw block reaches a designated position and hits a baffle, the roller stops rotating. A hot melt and cutting device is activated to fuse and cut the upper and lower baling belts, completing a set of straw blocks. However, dust is also generated during operation, making it difficult to transport straw. As can be seen, existing balers lack dust removal and purification capabilities. This dust not only affects the baling effect of the baler, but also easily damages the baler due to long-term wear and tear from the dust, shortening the baler's service life, making it inconvenient to use, and reducing the baler's efficiency and effectiveness. Therefore, a baling device with a dust removal function is needed to address the above-mentioned problems. Summary of the Invention

[0008] Furthermore, the second bundling module includes a packing module and a second hydraulic telescopic rod, the second hydraulic telescopic rod is fixedly installed inside the box, and the bottom end of the second hydraulic telescopic rod is fixedly connected to a second pressing plate.

[0009] Furthermore, the dust removal module includes a first air suction hood installed on the top of the first pressure plate, the first air suction hood is connected to a first connecting pipe, a blower is installed on the top of the box, the air inlet of the blower is connected to one end of the first connecting pipe, a dust collecting bin is installed on the top of the box, a second weighing sensor is fixedly installed inside the dust collecting bin, an electronic bin door is installed on the dust collecting bin, a vibrating screen is provided inside the box, a vibrating weighing sensor is installed on the vibrating screen, a second air suction hood is installed at the bottom of the vibrating screen, the bottom end of the second air suction hood is connected to a second connecting pipe, and a controller is installed on the outer wall of the box.

[0010] Furthermore, a filter screen is provided inside the fixed sleeve of the first connecting pipe.

[0011] Furthermore, a vibration motor is installed on one side of the box, and the vibration motor is connected to the vibration screen.

[0012] A method for dust removal and baling of straw, characterized by comprising the following steps:

[0013] Step 1: Turn on the device and perform a self-test to check whether each module has returned to its default state. If not, a pop-up window will appear on the controller's built-in display to remind the operator that the device has an abnormality and the self-test has failed. If the self-test passes, the device can operate normally.

[0014] Step 2: Open the first automatic sliding door on the feed port, and transport the grass into the box through the feeding module. At this time, read the value of the dust sensor and compare it with the set threshold. If it is higher than the set threshold, turn on the dust removal module to remove dust, including turning on the blower to work at the set speed, turning on the vibrating screen to work according to the set parameters, and opening the electronic door installed in the dust collection bin. If it is lower than the set threshold within a certain period of time, turn off the dust removal module.

[0015] Step 3: Weighing is performed using the first load cell below the feed port. When the set threshold is reached, the baling module is turned on, and the first pressing plate of the first baling module is moved back and forth between its starting position and its ending position to compress the grass. During this back-and-forth movement, the feeding of the feeding module is stopped. When the first pressing plate of the first baling module returns to its starting position, the feeding of the feeding module is resumed, and the back-and-forth movement is stopped at this time. The value of the first load cell is read again and compared with the set threshold, and step 3 is repeated.

[0016] Step 4: Read the value on the vibrating weighing sensor on the vibrating screen and compare it with the set hay bale weight. When the absolute value of the difference between the two is not greater than the set threshold value of the first weighing sensor below the feed port for the first time, the set threshold value of the first weighing sensor below the feed port is temporarily changed to the absolute value of the difference, and then changed back to the original set threshold value after the next feeding.

[0017] Step 5: The next feeding process is performed in the same manner as in Step 3. The first pressing plate of the first baling module is brought to its final position. If the dust sensor reading is not below its set threshold at this time, the controller adjusts the blower speed to increase the wind speed. If the reading remains below the set threshold within a certain period of time, a pop-up window alerts the operator of a device abnormality. Otherwise, the second baling module's packing module proceeds. After packing is complete, the second automatic sliding door on the discharge port is opened, the second pressing plate of the second baling module is activated, and the baled hay is pushed out to the discharge module, which is then activated for delivery.

[0018] Step 6: Synchronously read the second weighing sensor installed in the dust collection bin. If it exceeds the set threshold, stop all modules, close the first automatic sliding door, the second automatic sliding door, and the electronic bin door, and continue working after the dust collection bin is replaced.

[0019] Step 7: After completing all hay dust removal and baling, restore each module to the default value or user setting value and shut down the machine.

[0020] Furthermore, the default state includes the first automatic sliding door being closed, the second automatic sliding door being closed, the electronic compartment door being closed, the first pressure plate moving to the starting position, and the second pressure plate moving to the starting position, but does not include the working parameters set in the last operation. These working parameters will be retained, including vibration frequency, vibration amplitude, blower speed, dust sensor setting threshold, weighing sensor setting threshold, and a table of correspondence between hay bale weight and bale size.

[0022] The present invention utilizes the coordinated interaction between the vibrating screen, suction hood, and blower in the dust removal module to remove dust from the baling process, allowing dust to flow through the screen holes and the blower outlet into the dust collection bin. Mounting the suction hood on the pressure plate of the first baling module increases the dust collection range of crops. Combined with a dust sensor, the blower speed can be dynamically adjusted, improving dust removal while saving electricity. A built-in weighing sensor in the dust collection bin monitors bin fullness, resulting in a simple overall structure and ease of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A method for dust removal and baling of forage, comprising the following steps:

[0033] Step 1: Turn on the device and perform a self-test to check whether each module has been restored to its default state. If not, a pop-up window will be displayed on the controller's built-in display to alert the operator that the equipment has an abnormality and the self-test has failed. If the self-test passes, the device can operate normally. The default state includes the first automatic sliding door 102 being closed, the second automatic sliding door 602 being closed, the electronic compartment door 5041 being closed, the first pressure plate 302 moving to the starting position, and the second pressure plate 402 moving to the starting position. It does not include the working parameters set in the last operation. These working parameters will be retained, including vibration frequency, vibration amplitude, blower 507 speed, dust sensor 303 setting threshold, weighing sensor setting threshold, and a table of correspondence between hay bale weight and bale size.

[0034] Step 2: Open the first automatic sliding door 102 on the feed port 101, and transport the grass to the box 2 through the feed module 1. At this time, read the value of the dust sensor 303 and compare it with the set threshold. If it is higher than the set threshold, turn on the dust removal module 5 to remove dust, including turning on the blower 507 to work at the set speed, turning on the vibrating screen 501 to work according to the set parameters, and opening the electronic door 5041 installed in the dust collection bin 504. If it is lower than the set threshold within a certain period of time, turn off the dust removal module 5.

[0035] Step 3: The first load cell below the feed port 101 is used for weighing. When the set threshold is reached, the baling module is turned on and the first pressing plate 302 of the first baling module 3 is moved back and forth between its starting position and the ending position to compress the grass. During this back-and-forth movement, the feeding of the feeding module 1 is stopped. When the first pressing plate 302 of the first baling module 3 returns to the starting position, the feeding of the feeding module 1 is resumed. At this time, the back-and-forth movement is stopped, and the value of the first load cell is read again and compared with the set threshold, and step 3 is repeated.

[0036] Step 4: Read the value on the vibrating weighing sensor 502 on the vibrating screen 501 and compare it with the set hay bale weight. When the absolute value of the difference between the two is not greater than the set threshold value of the first weighing sensor below the feed port 101 for the first time, the set threshold value of the first weighing sensor below the feed port 101 is temporarily changed to the absolute value of the difference, and then changed back to the original set threshold value after the next feeding.

[0037] Step 5: The next feeding process proceeds as in Step 3. The first pressing plate 302 of the first baling module 3 is brought to its final position. If the dust sensor 303 reading is not below its set threshold, the controller adjusts the blower 507 speed to increase the wind speed. If the reading remains below the set threshold within a certain period of time, a pop-up window alerts the operator of a device abnormality. Otherwise, the second baling module 4 proceeds to the packing process. Once packing is complete, the second automatic sliding door 602 on the discharge port 601 is opened, and the second pressing plate 402 of the second baling module 4 is moved to its final position. The bundled hay is then pushed out to the discharge module 6, which is then opened for delivery.

[0038] Step 6: Synchronously read the second weighing sensor 5042 installed in the dust collection bin 504. If it exceeds the set threshold, stop all modules, close the first automatic sliding door 102, the second automatic sliding door 602, and the electronic compartment door 5041, and continue working after the dust collection bin is replaced.

[0039] Step 7: After completing all hay dust removal and baling, restore each module to the default value or user setting value and shut down the machine.
