Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a carrot harvester. Background Art

[0002] Traditional carrot harvesters mostly use a single-ridge harvesting and collection method. As a result, the single-ridge harvesting method is simple for harvesting carrots and has low harvesting efficiency. At the same time, in traditional designs, the carrot harvester is also fixedly mounted on a mobile carrier. As a result, it is easy for mobile carriers such as tractors to be unable to be used independently, which greatly causes equipment waste. Existing Chinese utility model patent CN202322649949.1 discloses a carrot harvester that can be detachably mounted on the mobile carrier, increasing the use time of the mobile carrier for other purposes. However, when the current carrot harvester is working, the driver cannot observe the height of the ridge, nor can he adjust the height of the front working section of the carrot harvester according to the height of the plants, which affects the actual harvesting quality. Utility Model Content

[0003] In view of the defects in the prior art, the utility model provides a carrot harvester, which can automatically adjust the harvesting mechanism according to the height of the ridge and the height of the plant, thereby improving the harvesting quality.

[0004] A carrot harvester comprising:

[0005] The mounting frame is detachably mounted on a mobile carrier; a harvesting mechanism is provided on the mounting frame, and a front end of the harvesting mechanism is hinged to the mounting frame;

[0006] The mounting frame is provided with at least one fixing hole; the mounting frame can be detachably mounted on the mobile carrier through the fixing hole;

[0007] A height sensing mechanism is provided at the lower front end of the harvesting mechanism, and a lifting support rod is hingedly provided at the tail end of the harvesting mechanism. The lower end of the lifting support rod is hinged to the mounting frame, and the lifting support rod is connected to a driving mechanism. The height sensing mechanism includes a horizontal fixing frame, the middle part of the horizontal fixing frame is hinged to the mounting frame, the front end of the horizontal fixing frame is rotatably provided with a roller, and the rear end of the horizontal fixing frame is provided with a fixing seat, and the fixing seat is an inverted "concave" structure. A screw is vertically provided at the position corresponding to the fixing seat on the mounting frame, and the screw vertically passes through the fixing seat and is fixed by bolts. A spring is sleeved on the screw, and the spring is provided under the fixing seat and abuts against the lower surface of the fixing seat. A sensing unit is provided on the fixing seat, and a signal output end of the sensing unit is connected to a signal processing unit, and the signal output end of the signal processing unit is connected to the signal input end of the driving mechanism.

[0008] The working process and principle of the above structure are as follows:

[0009] During harvesting operations, the roller contacts the ground. When encountering changes in height, the roller drives the horizontal fixed frame to swing, and the displacement of the fixed seat is transmitted to the sensing unit. The signal collected by the sensing unit is sent to the signal processing unit for processing, and a control command is issued. After receiving the command, the driving mechanism drives the lifting support rod to drive the height adjustment of the harvesting mechanism as the ground height changes, thereby adapting to different ground heights and plant heights. No human control is required, and the harvesting quality is more efficient.

[0010] Furthermore, the sensing unit includes a connecting rod and a pressure sensor, one end of the connecting rod is hinged to the fixing seat, and the other end is connected to the pressure sensor.

[0011] The connecting rod transmits the changes to the pressure sensor, and the pressure sensor transmits the signal to the signal processing unit based on the monitored pressure value.

[0012] Furthermore, the lifting support rod is a hydraulic rod, the driving mechanism is a hydraulic cylinder, and the hydraulic cylinder is connected to the hydraulic rod.

[0013] The hydraulic oil is transferred to the hydraulic rod through the hydraulic pump in the hydraulic cylinder, causing it to extend and retract.

[0014] Furthermore, the lifting support rod is a linear push rod, the driving mechanism is a driving motor, and the output end of the driving motor is connected to the linear push rod.

[0015] The electric drive motor drives the linear push rod to extend and retract, thereby achieving height adjustment of the harvesting mechanism.

[0016] Furthermore, the mounting frame has two horizontally parallel fixed square tubes.

[0017] This arrangement makes it easy for carrots to fall into the space between the two fixed square tubes, making it easier to harvest carrots.

[0018] Furthermore, an electric roller is provided above the harvesting mechanism, and a water hose is wound on the electric roller.

[0019] During harvesting, the water belt in the field is wound up and stored by an electric roller. At the same time, when the water belt is stored, the radish leaves on both sides of the water belt can be separated to facilitate subsequent harvesting.

[0020] From the above technical solution, it can be seen that the carrot harvester provided by the utility model has the following beneficial effects:

[0021] During the harvesting operation, the roller contacts the ground. When encountering changes in height, the roller drives the horizontal fixed frame to swing, and the displacement of the fixed seat is transmitted to the sensing unit. The signal collected by the sensing unit is sent to the signal processing unit for processing, and a control command is issued. After receiving the command, the driving mechanism drives the lifting support rod to drive the height of the harvesting mechanism to adjust as the ground height changes, thereby adapting to different ground heights and plant heights. No human control is required, and the harvesting quality is more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

The front end of the horizontal fixing frame 5 is rotatably provided with a roller 6, and the rear end of the horizontal fixing frame 5 is provided with a fixed seat 7. The fixed seat 7 is an inverted "concave" structure, and a screw rod 8 is vertically provided at the position corresponding to the fixed seat 7 on the mounting frame 1. The screw 8 vertically passes through the fixed seat 7 and is fixed by bolts. A spring 9 is sleeved on the screw 8, and the spring 9 is provided under the fixed seat 7 and abuts against the lower surface of the fixed seat 7. A sensing unit 10 is provided on the fixed seat 7. The signal output end of the sensing unit 10 is connected to the signal processing unit 11. The signal processing unit 11 is an ABB digital signal PFSK151 processing board. The signal output end of the signal processing unit 11 is connected to the signal input end of the driving mechanism 4.

[0034] The working process and principle of the above structure are as follows:

[0035] During harvesting operations, the roller 6 contacts the ground. When encountering changes in height, the roller drives the horizontal fixing frame 5 to swing, and the displacement of the fixing seat 7 is transmitted to the sensing unit 10. The signal collected by the sensing unit 10 is sent to the signal processing unit 11 for processing, and a control command is issued. After receiving the command, the driving mechanism 4 drives the lifting support rod 3 to drive the height adjustment of the harvesting mechanism 2 as the ground height changes, thereby adapting to different ground heights and plant heights. No human control is required, and the harvesting quality is more efficient.

[0036] In another embodiment of the present invention, Figure 3 As shown, the sensing unit 10 includes a connecting rod 13 and a pressure sensor 12 . One end of the connecting rod 13 is hinged to the fixing seat 7 , and the other end is connected to the pressure sensor 12 .

[0037] The connecting rod 13 transmits the change to the pressure sensor 12 , and the pressure sensor 12 transmits a signal to the signal processing unit 11 according to the pressure value detected.

[0038] In another embodiment of the present invention, Figure 1 As shown, the lifting support rod 3 is a hydraulic rod, the driving mechanism 4 is a hydraulic cylinder, and the hydraulic cylinder is connected to the hydraulic rod.

[0039] The hydraulic oil is transferred to the hydraulic rod through the hydraulic pump in the hydraulic cylinder, causing it to extend and retract.

[0040] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, the lifting support rod 3 is a linear push rod, the driving mechanism 4 is a driving motor, and the output end of the driving motor is connected to the linear push rod.

[0041] The height of the harvesting mechanism 2 is adjusted by driving the linear push rod with electric energy to extend and retract.

[0042] In another embodiment of the present invention, the mounting frame 1 has two horizontally parallel fixed square tubes 14 .

[0043] This arrangement facilitates the falling of carrots into the space between the two fixed square tubes 14, making it easier to harvest carrots.

At the same time, the device is rationally designed and easy to operate, achieving simultaneous harvesting and cleaning, greatly improving efficiency, and is therefore suitable for industry promotion.
