Description

Technical Field

[0001] This utility model belongs to the field of collection device technology, and specifically relates to a forage collection device. Background Technology

[0002] Forage refers to herbaceous plants whose stems and leaves can be used as feed for herbivores. It has the characteristics of strong regeneration ability, multiple harvests per year, and rich in various trace elements and vitamins, making it the first choice for raising livestock. When harvesting forage, a lot of forage stems and leaves are often left on the ground, which need to be collected to avoid waste. At present, machinery with collection rakes is mostly used to collect these forages. However, in the existing technology, such machinery lacks the ability to adapt to changes in terrain, which causes the collection rake to be suspended in many places, making it impossible to effectively pull the forage into the collection mechanism. Moreover, its function is relatively simple, and it cannot dry the forage at the same time as collecting it, which means that a separate process is required to dry the forage afterward. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a forage collection device. This device is equipped with a collector shell, support wheels, and a collection rake that can adapt to the terrain to maintain contact with the ground, thus preventing the collection rake from failing to effectively collect residual forage on the ground due to terrain changes. At the same time, through the setting of a collection hopper, a drying chamber, and a temporary storage chamber, the device can place the collected forage in three batches and simultaneously carry out three steps: initial collection and storage, drying, and post-drying storage awaiting removal. The device is equipped with a drying chamber, a solar collector, a circulation pipe, a fan, and an infrared heat pipe, which can dry the forage during the collection process while also achieving a certain degree of energy saving.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a forage collection device, comprising a main body, a traction frame connected to one end of the main body, wheels on the side of the main body, an adaptive collector at one end of the main body, a collection hopper installed inside the main body, a negative pressure fan installed on the top of the collection hopper, a first electric slide valve installed at the bottom of the collection hopper, the bottom of the first electric slide valve connected to a drying chamber, a second electric slide valve connected to one end of the drying chamber, the other side of the second electric slide valve connected to a temporary storage chamber, an outlet with a sealing door extending between the temporary storage chamber and the outer side of one end of the traction frame, a solar collector plate installed on the top of the traction frame, a fluid pipe installed inside the solar collector plate, both ends of the fluid pipe connected to a circulation pipe, a circulation pump installed in the middle section of the circulation pipe, ventilation pipes connected to the bottom and top of the drying chamber, a fan installed inside the ventilation pipe at the bottom of the drying chamber, an infrared heat pipe installed inside the ventilation pipe, and the circulation pipe extending into the inner side of the ventilation pipe.

[0005] The beneficial effects of this utility model are as follows: This device is equipped with a collector shell, support wheels, and a collection rake that can adapt to the terrain to maintain contact with the ground, thus avoiding the inability of the collection rake to effectively collect residual forage on the ground due to changes in terrain. At the same time, through the setting of the collection hopper, drying chamber, and temporary storage chamber, the collected forage can be placed in three batches, and the three steps of initial collection and storage, drying, and storage after drying for disposal can be carried out simultaneously. This device is equipped with a drying chamber, solar heat collection panel, circulation pipe, fan, and infrared heat pipe, which can dry the forage during the collection process while having a certain energy-saving effect.

[0006] To collect the remaining forage on the ground:

[0007] As a further improvement to the above technical solution: the adaptive collector includes a collector mounting base installed at one end of the main body of the device. An electric telescopic rod is installed on the top of the collector mounting base. The piston rod of the electric telescopic rod passes through the collector mounting base and is connected to the lifting plate. An adaptive telescopic mechanism is provided at the bottom of the lifting plate. The bottom of the adaptive telescopic mechanism is connected to the collector housing. A support wheel is installed on the side of the collector housing. A dual-output shaft gear reducer is installed on the side of the support wheel. The input shaft of the dual-output shaft gear reducer is connected to a first motor. The two output shafts of the dual-output shaft gear reducer are respectively connected to a collecting rake and a bidirectional spiral conveying shaft. The other ends of the collecting rake and the bidirectional spiral conveying shaft are rotatably connected to the inner wall of the collector housing.

[0008] The beneficial effects of this improvement are as follows: When collecting residual forage on the ground, the first motor drives the dual-output shaft gear reducer to operate. The two output shafts of the dual-output shaft gear reducer drive the collecting rake and the bidirectional spiral conveyor shaft to rotate respectively. The collecting rake moves the forage on the ground and throws it into the inner side of the collector housing. The bidirectional spiral conveyor shaft gathers the forage towards the center. The negative pressure fan draws negative pressure into the negative pressure hose to form a negative pressure airflow. The negative pressure hose then draws the forage in the center into the collecting hopper and discharges it into the collecting hopper.

[0009] In order for this device to maintain effective collection of residual forage on the ground:

[0010] As a further improvement to the above technical solution: the adaptive telescopic mechanism includes a hydraulic spring damper, and the top and bottom of the hydraulic spring damper are connected to universal joints. The universal joint at the top is connected to the lifting plate, and the universal joint at the bottom is connected to the collector housing.

[0011] The beneficial effects of this improvement are as follows: due to the installation of the universal ball joint, the hydraulic spring damper can adaptively rotate and extend and retract as the terrain changes during the movement of this device, thereby allowing the collector shell to remain in contact with the ground through the support wheels, enabling this device to maintain effective collection of residual forage on the ground.

[0012] The collected fodder is then drawn into the collection hopper:

[0013] As a further improvement to the above technical solution: one end of the collecting hopper is connected to the collector housing via a negative pressure hose.

[0014] The beneficial effect of this improvement is that the negative pressure hose serves as the channel for drawing the collected forage into the collection hopper.

[0015] In order to input airflow into the drying chamber and to output airflow from inside the drying chamber:

[0016] As a further improvement to the above technical solution: a filter screen is installed inside the ventilation duct, the bottom of the lower ventilation duct extends through the bottom of the main body of the device, and the upper ventilation duct extends through the side of the main body of the device.

[0017] The beneficial effects of this improvement are: the filter screen is used to prevent feed from leaking out of the ventilation duct; the bottom of the lower ventilation duct extends through the bottom of the main body of the device to draw in air; and the upper ventilation duct extends through the side of the main body of the device to exhaust airflow.

[0018] For power supply to this device:

[0019] As a further improvement to the above technical solution: a storage battery is installed on the inner side of the traction frame.

[0020] The beneficial effect of this improvement is that the storage battery is used to power this device.

[0021] To facilitate the transfer of feed from the drying silo to the temporary storage silo:

[0022] As a further improvement to the above technical solution: a second motor is installed at one end of the drying chamber, and the output shaft of the second motor is connected to a unidirectional spiral conveyor shaft.

[0023] The beneficial effects of this improvement are: the second motor can drive the unidirectional screw conveyor shaft to rotate, helping the forage in the drying chamber to be discharged into the temporary storage chamber.

[0024] In order to expel the airflow drawn in by the negative pressure fan:

[0025] As a further improvement to the above technical solution: the side of the negative pressure fan is connected to an exhaust pipe, and one end of the exhaust pipe extends through the side of the main body of the device.

[0026] The beneficial effect of this improvement is that the exhaust pipe is used to discharge the airflow drawn in by the negative pressure fan.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0040] like Figure 1-10 As shown, a forage collection device includes a main body 2, one end of which is connected to a traction frame 1.

One end of the drying chamber 19 is connected to a second electric slide valve 22, and the other end of the second electric slide valve 22 is connected to a temporary storage chamber 23. An outlet with a sealing door 24 is installed between the outer side of one end of the traction frame 1 and the hopper 23. A solar collector 25 is installed on the top of the traction frame 1. A fluid pipe 26 is installed on the inner side of the solar collector 25. Both ends of the fluid pipe 26 are connected to a circulation pipe 28. A circulation pump 27 is installed in the middle section of the circulation pipe 28. Ventilation pipes 30 are connected to the bottom and top of the drying hopper 19.

The circulation pipe 28 penetrates into the inner side of the ventilation pipe 30.

[0041] This device is equipped with a collector housing 9, support wheels 10, and a collection rake 13 that can adapt to the terrain to maintain contact with the ground. This prevents the collection rake 13 from failing to effectively collect residual forage on the ground due to changes in terrain. At the same time, through the setting of the collection hopper 17, drying chamber 19, and temporary storage chamber 23, the collected forage can be placed in three batches and the three steps of initial collection and storage, drying, and storage after drying for disposal can be carried out simultaneously. The device is equipped with a drying chamber 19, solar collector 25, circulation pipe 28, fan 29, and infrared heat pipe 32, which can dry the forage during the collection process while having a certain energy-saving effect.

[0042] The adaptive collector includes a collector mounting base 4 installed at one end of the main body 2. An electric telescopic rod 5 is installed on the top of the collector mounting base 4. The piston rod of the electric telescopic rod 5 passes through the collector mounting base 4 and is connected to the lifting plate 6. An adaptive telescopic mechanism is provided at the bottom of the lifting plate 6. The bottom of the adaptive telescopic mechanism is connected to the collector housing 9. A support wheel 10 is installed on the side of the collector housing 9. A dual-output shaft gear reducer 12 is installed on the side of the support wheel 10. The input shaft of the dual-output shaft gear reducer 12 is connected to the first motor 11. The two output shafts of the dual-output shaft gear reducer 12 are respectively connected to the collecting rake 13 and the bidirectional spiral conveying shaft 14. The other ends of the collecting rake 13 and the bidirectional spiral conveying shaft 14 are rotatably connected to the inner wall of the collector housing 9.

[0043] When collecting the remaining forage on the ground, the first motor 11 drives the dual-output shaft gear reducer 12 to operate. The two output shafts of the dual-output shaft gear reducer 12 drive the collecting rake 13 and the bidirectional spiral conveyor shaft 14 to rotate respectively. The collecting rake 13 moves the forage on the ground and throws it into the inner side of the collector housing 9. The bidirectional spiral conveyor shaft 14 gathers the forage towards the center. The negative pressure fan 16 draws negative pressure into the negative pressure hose 15 to form a negative pressure airflow. The negative pressure hose 15 then draws the forage from the bidirectional spiral conveyor shaft 14 into the center and discharges it into the collecting hopper 17.

[0044] The adaptive telescopic mechanism includes a hydraulic spring damper 8, with universal joints 7 connected to both the top and bottom of the hydraulic spring damper 8. The top universal joint 7 is connected to the lifting plate 6, and the bottom universal joint 7 is connected to the collector housing 9.

[0045] Because of the universal ball joint 7, the hydraulic spring damper 8 can adaptively rotate and extend and retract as the terrain changes during the movement of this device, so that the collector housing 9 can be kept in contact with the ground through the support wheel 10, enabling this device to effectively collect residual forage on the ground.

[0046] One end of the collecting hopper 17 is connected to the collector housing 9 via a negative pressure hose 15.

[0047] The negative pressure hose 15 serves as the channel for collecting feed into the collection hopper 17.

[0048] The ventilation duct 30 is equipped with a filter screen 31. The bottom of the lower ventilation duct 30 extends through the bottom of the device body 2, and the upper ventilation duct 30 extends through the side of the device body 2.

[0049] The filter screen 31 is used to prevent feed from leaking out of the ventilation duct 30. The bottom of the lower ventilation duct 30 extends through the bottom of the device body 2 to draw in air, and the upper ventilation duct 30 extends through the side of the device body 2 to exhaust airflow.

[0050] A storage battery 33 is installed on the inner side of the traction frame 1.

[0051] Battery 33 is used to power this device.

[0052] A second motor 20 is installed at one end of the drying chamber 19, and the output shaft of the second motor 20 is connected to the unidirectional spiral conveyor shaft 21.

[0053] The second motor 20 can drive the unidirectional spiral conveyor shaft 21 to rotate, helping the feed in the drying chamber 19 to be discharged into the temporary storage chamber 23.

[0054] The side of the negative pressure fan 16 is connected to an exhaust pipe 34, one end of which extends through the side of the main body 2 of the device.

[0055] The exhaust pipe 34 is used to discharge the airflow drawn in by the negative pressure fan 16.

[0056] The working principle and usage process of this utility model are as follows: When in use, this device is connected to a tractor via a towing frame 1. The tractor pulls the device to move it. During operation, the electric telescopic rod 5 drives the lifting plate 6 to descend, causing the support wheel 10 to contact the ground and compress the hydraulic spring damper 8. The pressure provided by the hydraulic spring damper 8 firmly presses the collector housing 9 onto the ground via the support wheel 10. Due to the universal joint 7, the hydraulic spring damper 8 can adaptively rotate and extend / retract as the terrain changes during the device's movement, thus maintaining the collector housing 9 in contact with the ground via the support wheel 10. This allows the device to effectively collect residual forage on the ground. When collecting residual forage on the ground, the first motor 11 drives the dual-output shaft gear reducer 12 to operate. The two output shafts of the dual-output shaft gear reducer 12 drive the collecting rake 13 and the bidirectional spiral conveyor shaft 14 to rotate respectively. The collecting rake 13 moves the forage on the ground and throws it into the inner side of the collector housing 9. The bidirectional spiral conveyor shaft 14 gathers the forage towards the center. The negative pressure fan 16 draws negative pressure into the negative pressure hose 15 to form a negative pressure airflow. The negative pressure hose 15 then draws the forage from the center into the collecting hopper 17 and discharges it into the collecting hopper 17. By controlling the first electric slide valve 18 to open, the forage inside the collecting hopper 17 can be discharged into the drying chamber 19. This device is equipped with solar energy collection. The heating plate 25 absorbs solar radiation heat through the solar collector 25 and quickly conducts the heat to the circulation pipe 28. The circulation pump 27 circulates the fluid within it. When the hot fluid flows into the portion of the circulation pipe 28 located inside the ventilation duct 30, the airflow from the fan 29 contacts and absorbs the heat from the circulation pipe 28, forming hot air that dries the forage inside the drying chamber 19. This provides a heat source without energy consumption, enabling the device to dry forage while also being energy-efficient. When sunlight is not strong, the infrared heat pipe 32 can be turned on to further heat the airflow and ensure drying effectiveness. The second electric motor can then be activated. The slide valve 22 allows the dried forage in the drying chamber 19 to be discharged into the temporary storage chamber 23. During this process, the second motor 20 is turned on, driving the unidirectional screw conveyor shaft 21 to rotate. The unidirectional screw conveyor shaft 21 assists in discharging the forage from the drying chamber 19 into the temporary storage chamber 23. Opening the sealing door 24 allows the forage in the temporary storage chamber 23 to be cleared and collected. In summary, this device is equipped with a collector housing 9, support wheels 10, and a collection rake 13 that can adapt to the terrain to maintain contact with the ground, preventing the collection rake 13 from failing to effectively collect residual forage on the ground due to changes in terrain. At the same time, through the arrangement of the collection hopper 17, drying chamber 19, and temporary storage chamber 23, the collected forage can be placed in three batches.The device simultaneously performs three steps: initial collection and storage of forage, drying, and post-drying storage awaiting disposal. It is equipped with a drying chamber 19, solar collectors 25, circulation pipes 28, a fan 29, and infrared heat pipes 32. This allows for the drying of forage during the collection process while also achieving energy savings.
