Description

Technical Field

[0001] The utility model relates to the technical field of round grass bale collecting equipment, in particular to a round grass bale picking and transporting vehicle. Background Art

[0002] With the adjustment of the country's "grain to feed" policy, animal husbandry machinery has leapt from an unknown small category to a hot spot of production. With the progress of the animal husbandry breeding industry, the promotion of environmental governance and the vigorous development of the straw post-processing industry, the round baler market has entered the fast lane of development from its original slow growth due to the characteristics of heavy bales and low transportation cost of bales. With the large-scale use of round balers, traditional manual picking methods are unable to pick up heavy round bales.

[0003] Chinese patent publication number CN211152821U discloses a round bale picking and transporting vehicle, which is mainly used to pick up the round bales packed by the field round baler one by one and put them onto the round bale picking and transporting vehicle. When the bales are full, the picking and transporting vehicle arrives at the designated location to unload the round bales. Only one person is required to operate the whole process of the operation. It is used to improve the inconvenience of the traditional picking method, reduce labor intensity, reduce corresponding supporting equipment, reduce production costs, improve production efficiency, and simplify the operation process.

[0004] The above patent mainly picks up the round hay bale by flipping the picking arm and places it on the upper end of the cart. However, due to the heavy weight of the round hay bale, the center of the device will be greatly deflected in the process of the picking arm driving the round hay bale to flip. Moreover, since the picking arm is located on one side of the cart, it is easy to flip the cart after the center changes. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-4The utility model discloses a round grass bale picking and transporting vehicle, including a grass cart 1, a driving wheel 2 is provided at the bottom end of the grass cart 1, a plurality of positioning grooves 3 are opened at the upper end of the grass cart 1, rotating shafts 4 are provided on both sides of the inner part of the positioning grooves 3, and the two rotating shafts 4 are commonly connected with a supporting push plate 5, a connecting shaft 6 is rotatably installed at one end of the grass cart 1, and a connecting frame 7 is sleeved on the outer surface of the connecting shaft 6, and extension sleeves 8 are slidably connected at both ends of the connecting frame 7, and one end of the two extension sleeves 8 is commonly connected with a transverse air pressure cylinder 9, and a fixed bracket 10 is provided at the upper end of the grass cart 1 near the connecting shaft 6, and a hydraulic telescopic rod 11 is provided on one side of the fixed bracket 10, and the end of the hydraulic telescopic rod 11 away from the fixed bracket 10 is connected to one side of the transverse air pressure cylinder 9.

[0025] In this embodiment, the forage cart 1 is moved by the driving wheel 2 so that one end of the forage cart 1 on which the rotating shaft 4 is installed is flush with the outer cylindrical surface of the round hay bale, and the transverse air pressure cylinder 9 is pressed downward by the hydraulic telescopic rod 11 so that the frame formed by the extension sleeve 8, the transverse air pressure cylinder 9 and the connecting frame 7 is sleeved on the outer surface of the round hay bale, and the connecting frame 7 and the extension sleeve 8 are unfolded through the outer arc surface of the round hay bale so that the frame is sleeved on the lower side of the outer surface of the round hay bale, and then the device is lifted upward by the setting of the hydraulic telescopic rod 11, and the forage bale is lifted upward until the forage bale rolls to the top of the forage cart 1, and the positioning groove 3 is set to improve the stability of the forage bale, and the setting of the support push plate 5 facilitates the rolling of the forage bale on the top of the forage cart 1, thereby facilitating the placement of the forage bale.

[0026] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the support push plate 5 includes two hydraulic push rods 51, and the two hydraulic push rods 51 are respectively fixedly mounted on the groove walls at both ends of the inner side of the positioning groove 3, and the telescopic ends of the two hydraulic push rods 51 are commonly connected to a driving shaft 52, and the outer surface of the driving shaft 52 is sleeved with a plurality of telescopic connecting rods 53.

[0027] In this embodiment, two hydraulic push rods 51 are used to install the pushing shaft 52. When in use, the pushing shaft 52 is pushed upward by the hydraulic push rod 51, so as to change the angle between the telescopic connecting rod 53 and the forage cart 1. When the pushing shaft 52 is recessed downward, the groove wall of the positioning groove 3 can achieve the effect of fixing the forage bale. When the pushing shaft 52 protrudes upward from the upper end surface of the forage cart 1, the telescopic connecting rod 53 forms a bulge, so as to achieve the effect of pushing out the forage bale for easy unloading. When the pushing shaft 52 is flush with the upper end surface of the forage cart 1, the upper surface of the telescopic connecting rod 53 is flush with the forage cart 1, so as to achieve the effect of facilitating the rolling of the forage bale on the upper surface of the forage cart 1.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, one end of two adjacent telescopic connecting rods 53 away from the driving shaft 52 is connected to the two rotating shafts 4 respectively.

[0029] In this embodiment, since the ends of adjacent telescopic links 53 are respectively connected to the two rotating shafts 4, it is convenient to change the position of the pushing shaft 52 by the hydraulic push rod 51, thereby changing the angle between the two adjacent telescopic links 53 and the forage cart 1.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, an air pressure cavity tube 91 is arranged inside the transverse air pressure cylinder 9, and two groups of pressure valve plates 92 are arranged at the top end of the air pressure cavity tube 91. The top end of the pressure valve plate 92 passes through the transverse air pressure cylinder 9, and a pressure plate 93 is commonly arranged at the top end of the two pressure valve plates 92.

[0031] In this embodiment, the air pressure chamber 91 is provided to form an air chamber inside the transverse air pressure cylinder 9. Under normal circumstances, the air pressure inside the air pressure chamber 91 is equal to that of the outside, and the end of the connecting frame 7 is completely inserted into the extension sleeve 8. At this time, the air inside the extension sleeve 8 is almost zero. After the transverse air pressure cylinder 9 is pressed downward by the hydraulic telescopic rod 11 and contacts the round hay bale, the outer wall of the round hay bale will push the transverse air pressure cylinder 9, so that the extension sleeve 8 and the connecting frame 7 extend to each other and inhale air from the inside of the air pressure chamber 91. At this time, the internal air pressure of the extension sleeve 8 and the air pressure chamber 91 is less than the external atmospheric pressure. When it moves to the bottom of the round hay bale, the outer wall of the round hay bale will not affect the horizontal air pressure cylinder 9. At this time, the negative pressure inside the extension sleeve 8 and the air pressure cavity tube 91 will make the extension sleeve 8 and the connecting frame 7 close again. At this time, the air completely enters the interior of the air pressure cavity tube 91, and then the horizontal air pressure cylinder 9 is pulled upward by the hydraulic telescopic rod 11. At this time, the round hay bale will exert pressure on the pressure plate 93, so that the pressure valve plate 92 blocks the two ends of the air pressure cavity tube 91. At this time, the air cannot enter the interior of the extension sleeve 8, resulting in the extension sleeve 8 and the connecting frame 7 cannot be pulled apart, so that the horizontal hydraulic rod can lift the round hay bale, thereby achieving the effect of picking up the round hay bale.

[0032] In a further preferred embodiment of the present invention, Figure 1-4 As shown, both ends of the hydraulic telescopic rod 11 are rotatably mounted with adjustment shafts 12 , and both ends of the hydraulic telescopic rod 11 are rotatably connected to the fixed bracket 10 and the transverse air pressure cylinder 9 through the adjustment shafts 12 .

[0033] In this embodiment, the adjustment shaft 12 is provided to connect the two ends of the hydraulic telescopic rod 11 with the fixed bracket 10 and the transverse air pressure cylinder 9 .

[0034] In a further preferred embodiment of the present invention, Figure 1-4 As shown, rotating rollers 13 are provided on the bottom sides of the connecting frame 7 and the transverse air pressure cylinder 9 .

[0035] In this embodiment, by providing the rotating roller 13, when the transverse air pressure cylinder 9 is sleeved on the outer surface of the round hay bale, the friction force is reduced to prevent the round hay bale from being damaged.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
