Description

Technical Field

[0001] This utility model relates to the technical field of square bale picking and palletizing machines, specifically to a photoelectric picking trigger device for square bale picking and palletizing machines. Background Technology

[0002] Currently, the picking triggering device of the square bale picking and palletizing machine is a mechanical triggering device. When the operator of the square bale picking and palletizing machine picks up a bale, the bale enters the picker and hits the mechanical trigger rod. The rear end of the trigger rod is equipped with a trigger metal plate and an inductive proximity switch. When the metal plate approaches the proximity switch, the proximity switch triggers an electrical signal, which drives the motor to rotate through the control circuit, thereby achieving the purpose of identifying the bale entering the picker.

[0003] However, this method is limited by factors such as the shape, size, and angle of the hay bales, and there is a certain probability that it will not be triggered. When it cannot be triggered, it is necessary to adjust the vehicle by stopping or reversing to trigger it again or to trigger it manually, which reduces the efficiency of automatic picking and also has a certain chance of damaging the hay bales. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a photoelectric picking trigger device for a square bale picking and stacking machine, which improves the success rate of bale detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photoelectric pickup triggering device for a square bale pickup and palletizing machine includes a diffuse reflection photoelectric switch, a connecting seat, and a base. The base is bolted to the front lintel of the pickup unit of the square bale pickup and palletizing machine. The connecting seat is hinged to the base and has an elongated hole. The diffuse reflection photoelectric switch is bolted to the connecting seat through the elongated hole and has a detection distance adjustment knob. After installation, the diffuse reflection photoelectric switch monitors the ground. The bale and the ground form a height difference, and the presence of the bale is detected by utilizing the principle that light reflection from objects at different heights can be detected.

[0007] Furthermore, the connecting seat is L-shaped and consists of two mutually perpendicular plates. One plate has connecting ears at both ends for hinged connection with the base, and the other plate has an elongated hole for connection with the diffuse reflection photoelectric switch.

[0008] Furthermore, the connecting ear has a chamfer.

[0009] Furthermore, the base includes a base plate and ear plates; the ear plates are vertically fixed to both sides of one end of the base plate, and the base plate is provided with bolt holes.

[0010] Furthermore, the end of the ear plate is chamfered.

[0011] Furthermore, the diffuse reflection photoelectric switch is connected in parallel with the sensor of the mechanical triggering device of the square bale picking and palletizing machine.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is installed on the front lintel of the pickup unit of a square hay bale pickup and palletizer. After installation, a diffuse reflection photoelectric switch monitors the ground. The hay bale is at a height difference with the ground, and the presence of the hay bale is detected by utilizing the principle that light reflection from objects at height differences can be detected. Compared with traditional mechanical triggering devices, this invention overcomes the limitation that hay bales cannot trigger mechanical triggering devices in certain situations. The diffuse reflection photoelectric switch of this utility model has a high detection success rate and is suitable for harsh working conditions of agricultural machinery. Moreover, it can detect hay bales in advance, while mechanical triggering devices are relatively lagging. Early motor triggering can improve the pickup success rate, reduce the hay bale breakage rate, and improve overall pickup efficiency.

[0014] 2. This utility model's diffuse reflection photoelectric switch is equipped with a detection distance adjustment knob, which can adjust the detection distance of the reflection, used to adjust the reflective surface height of hay bales of different heights; the connecting base has an angle adjustment slot, which can adjust the relative angle between the diffuse reflection photoelectric switch and the connecting base, used to adjust the lateral detection point at the front of the pickup; the connecting base is hinged to the base, used to adjust the forward tilt detection angle of the diffuse reflection photoelectric switch. Through these three adjustments, the three-axis detection points of the diffuse reflection photoelectric switch are adjusted, thereby improving the detection success rate.

[0015] 3. The diffuse reflection photoelectric switch of this utility model is connected in parallel with the mechanical triggering device sensor. When either the mechanical or photoelectric triggering device sensor has a trigger signal, it will trigger the picking motor to work and drive the picking chain to pick up the bales.

[0016] 4. The connector of this utility model is L-shaped, which has strong stability, strong spatial adaptability, convenient installation and high structural strength.

[0017] 5. The connecting ear and ear plate of this utility model are chamfered, which improves safety and ease of assembly, and optimizes structural strength. Attached Figure Description

[0030] like Figure 1 As shown, a photoelectric pickup triggering device for a square bale pickup and palletizing machine includes a diffuse reflection photoelectric switch 1, a connecting base 2, and a base 3. The diffuse reflection photoelectric switch 1 is an existing product, preferably the BOSR090K-PU-ID11 type, and the diffuse reflection photoelectric switch 1 is equipped with a detection distance adjustment knob.

[0031] The connecting base 2 is L-shaped and consists of two perpendicular plates. One plate has connecting ears 21 at both ends for hinged connection with the base 3. The connecting ears 21 have bolt holes in the middle and chamfers 23 at the ends. The other plate has an elongated hole 22 for connecting with the diffuse reflection photoelectric switch 1. The connecting base 2 of this utility model is L-shaped, which has strong stability, strong spatial adaptability, convenient installation, and high structural strength.

[0032] The base 3 includes a base plate 31 and ear plates 32. The base plate 31 is a flat plate with two parallel bolt holes at its bottom end. The two ear plates 32 are parallel and perpendicular to each other and fixed to the two sides of the top end of the base plate 31. The front end of the ear plates 32 is chamfered 23.

[0033] The two connecting ears 21 of the connecting seat 2 are placed between the two ear plates 32 of the base 3. The connecting ears 21 and the ear plates 32 are connected by bolts, thereby hinged the connecting seat 2 to the base 3.

[0034] Both the connecting ear 21 and the ear plate 32 of this utility model are provided with chamfers 23, which improves safety and assembly convenience, and optimizes structural strength.

[0035] like Figure 5 As shown, the diffuse reflection photoelectric switch 1 is connected in parallel with the sensor (inductive proximity switch) of the mechanical triggering device of the bale picking and palletizing machine. When either the mechanical triggering device or the diffuse reflection photoelectric switch 1 receives a trigger signal, the picking motor will be triggered to work, and the picking chain will be driven to pick up the bale.

[0036] like Figure 2 , Figure 3 As shown, the base 3 is bolted to the front lintel 4 of the picker of the bale picker and palletizer, and is installed in the middle of the lintel 4. The base 3 is fixed to the picker by bolts for easy disassembly. After installation, the diffuse reflection photoelectric switch 1 monitors the ground. The bale and the ground form a height difference. The presence of the bale is detected by utilizing the principle that light reflection from objects with height differences can be detected.

[0037] Adjustment of diffuse reflection photoelectric switch 1: (1) The diffuse reflection photoelectric switch is equipped with a detection distance adjustment knob, which can adjust the detection distance of the reflection, and is used to adjust the height of the reflective surface of the straw bales of different heights. (2) This utility model has lateral and forward tilt angle adjustment. The other plate of the connecting seat 2 is provided with a long strip hole 22 for connecting with the diffuse reflection photoelectric switch 1, which can adjust the relative angle between the switch and the plate, and is used to adjust the lateral detection point at the front of the pickup. (3) The connecting seat 2 is hinged to the base 3. The connecting seat 2 can rotate, and is used to adjust the forward tilt detection angle of the diffuse reflection photoelectric switch. The above three adjustment points can adjust the three-axis detection points of this device, thereby improving the detection success rate.

[0038] Instructions for use: (e.g.) Figure 3 As shown, when there is no bale in front of the pickup, first adjust the height, angle, etc. of this device to a no-signal state to ensure that there is no detection signal when there is no bale, thus preventing false activation; Figure 4 As shown, when the picker has 5 bales of grass, adjust the device to have a signal and set a certain downward detection height to prevent fluctuations in the detection of grass bales due to ground elevation errors.

[0039] This invention utilizes the principle of light reflection from objects at different heights to detect the presence of hay bales. Compared to traditional mechanical triggering devices, it overcomes the limitation that hay bales cannot trigger mechanical triggering devices in certain situations. The diffuse reflection photoelectric switch of this invention has a high success rate and is suitable for harsh working conditions of agricultural machinery. Moreover, it can detect hay bales in advance, while mechanical triggering devices are relatively lagging. Early motor triggering can improve the success rate of picking up hay bales, reduce the breakage rate of hay bales, and improve the overall picking efficiency.

[0040] The above description is only a part of the specific embodiments of this utility model. The protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and utility model concept of this utility model, should be included within the protection scope of this utility model.
