DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1-6 shown, this embodiment provides a bale placement rack, which includes a plurality of vertically arranged bale placement racks 1. There are 5 layers of bale placement racks 1 in total, and it can also be increased or decreased according to actual needs. The working principles are the same. When not working, all the bale placement racks 1 are at the bottom. After working, one layer is filled and raised by one layer;

[0028] Lifting beams 2 are arranged on both lateral sides of the bale placement rack 1, and lifting tracks 3 are arranged on the lifting beams 2. Both lateral sides of the bale placement rack 1 are installed on the lifting tracks 3;

[0029] A lifting mechanism 4 is installed on each side of the lifting beam 2, and the output end of the lifting mechanism 4 is successively connected to the bale placement rack 1; the bale placement rack 1 is successively lifted or lowered through the lifting mechanism 4.

[0030] As a preferred embodiment, the lifting mechanism 4 is an oil cylinder, a guide wheel 5 is installed at the output end of the oil cylinder, and a steel wire rope 6 is passed through the guide wheel 5 and then successively connected to each bale placement rack 1.

[0031] In another embodiment of the present application, as Figure 4 shown, a lifting mechanism 4 is only installed on the lifting beam 2 on one side. A guide wheel 5 is installed at the output end of the lifting mechanism 4. Two steel wire ropes 6 are passed through the guide wheel 5 and respectively connected to the lateral two ends of each bale placement rack 1. One of the steel wire ropes 6 bypasses from the top of the bale placement rack 1 and is connected to the other end of the bale placement rack 1. The bale placement rack 1 is successively lifted or lowered by driving the steel wire rope 6 through the lifting mechanism 4.

[0032] In another embodiment of the present application, as Figure 1 shown, the bale placement rack 1 includes a cross beam 101. The lateral two ends of the cross beam 101 are installed on the lifting track 3 through bearings. A plurality of longitudinal placement beams 102 are arranged on the cross beam 101. The lateral length of the cross beam 101 is slightly larger than the lateral width of a plurality of bales placed side by side, and the longitudinal length of the longitudinal placement beam 102 is slightly larger than the longitudinal length of a plurality of bales placed side by side.

[0033] In another embodiment of the present application, as Figure 1As shown in the figure, on the outer sides of the longitudinally placed beams 102 at the transverse two ends of the cross beam 101, there are support beams 103 inclined downward. At one end of the support beam 103 away from the cross beam 101, a roller 104 is installed. The roller 104 is in contact with the lifting beam 2. When bales are placed on the longitudinally placed beams 102, the support beam 103 can provide a supporting force to prevent the bale placement rack 1 from tilting.

[0034] This embodiment provides a bale pickup vehicle, which includes a bale placement rack 1. Below the bale placement rack 1, there is a vehicle frame 7. The lifting beam 2 is fixed on the vehicle frame, and wheels 8 are installed at the bottom of the vehicle frame 7;

[0035] On one side of the vehicle frame 7 in the transverse direction, there is a traction 9 and a bale pickup 10. The traction 9 is used to connect with a baler or a tractor, etc., and drives the bale pickup vehicle to move through the baler or the tractor;

[0036] On one side of the bale placement rack 1 in the longitudinal direction, there are multiple longitudinally arranged idler rollers 11. On the side of the idler roller 11 away from the bale placement rack 1, there is a toggle rod 12. The lower end of the toggle rod 12 is connected to two toggle link arms 13. One end of the toggle link arm 13 away from the toggle rod 12 is connected to a transmission component. The toggle rod 12 is higher than the idler roller 11. When the idler roller 11 is full of bales, the toggle rod 12 is located outside the bales. The transmission component drives the toggle rod 12 to move towards the bale placement rack 1, thereby moving the bales onto the bale placement rack 1. The toggle link arm 13 passes through the gap of the longitudinally placed beam 102 and continues to move the bales to the designated position;

[0037] In this embodiment, the transmission component is a chain drive. The chain is installed on the gear, and the toggle link arm 13 is installed on the chain. The chain drives the toggle link arm 13 and the toggle rod 12 to move from the side of the idler roller 11 to above the idler roller 11, thereby enabling the toggle rod 12 to move longitudinally and moving the bales onto the bale placement rack 1. During the movement, the toggle link arm 13 passes through the gap between the idler roller 11 and the longitudinally placed beam 102; when it is necessary to unload the bales onto the conveyor 15, the transmission component drives the toggle rod 12 to move towards the conveyor 15, thereby causing the bales to fall onto the conveyor 15.

[0038] As a preferred embodiment, the bale pickup 10 is arranged on one side of the idler roller 11 in the transverse direction, and the bales are picked up by the bale pickup 10 and move transversely along the idler roller 11.

[0039] In another embodiment of the present application, there is a certain gap between the bale pickup 10 and the idler roller 11, and the bales are likely to fall or get stuck, resulting in unsmooth operation of the equipment. Therefore, a first cage 14 is provided between the bale pickup 10 and the idler roller 11 to enable the bales to smoothly move from the bale pickup 10 to the idler roller 11.

[0040] In another embodiment of the present application, when the bale rack is filled with bales on each layer, the bales need to be transported to a designated vehicle or a storage warehouse. Therefore, a conveyor 15 is provided on the side of the bale rack 1 away from the idler 11. The conveyor 15 is a foldable bale unloading conveyor, which does not occupy too much space. By controlling the toggle rod 12, the bales are unloaded onto the conveyor in sequence from the bottom layer to the top layer.

[0041] In another embodiment of the present application, a pair of gears 16 are installed at the transverse two ends of the bale picker 10, and a barbed chain 17 is installed on each pair of gears 16; a second roller cage 18 is installed at one end of the bale picker 10 close to the idler 11, and the barbed chain 17 can more conveniently grab and move the bales.

[0042] In another embodiment of the present application, two pairs of gears 16 are installed at the transverse two ends of the bale picker 10, and a barbed chain 17 is installed on each pair of gears 16; a second roller cage 18 is installed at one end of the bale picker 10 close to the idler 11, and the barbed chain 17 can more conveniently grab and move the bales.

[0043] Working process and principle

[0044] The bale pick-up vehicle is driven by the power of the tractor in front. In the initial state, the bale rack 1 is lowered by controlling the steel wire rope 6 through the oil cylinder and stacked together; and the upper surface of the top bale rack 1 is horizontal with the top end of the idler 11, or the bale rack 1 is slightly lower than the top end of the idler 11, so that the bales can be smoothly moved onto the bale rack 1; the bale picker 10 is equipped with two rows of barbed chains 17. When the tractor is moving forward, it will pick up the bales and transport them to the idler 11 until the idler 11 is filled with bales, and then they are pushed onto the top bale rack 1 by the toggle rod 12. When the top bale rack 1 is filled, it is lifted to the top by the lifting beam 2; repeat the above process until all 5 layers of bale racks 1 are filled, and then the bales are directly transported to the truck through the grass conveyor, and the workers on the truck stack them into stacks.

[0045] It should be noted that in the present application, the power sources of the bale picker 10, the toggle rod 12 and the conveyor 15 are provided by the tractor, the baler or other vehicles that tow the bale pick-up vehicle, and can be combined through drive shafts and gears, etc. This part is the prior art and will not be elaborated here; the bale pick-up vehicle has two operation modes. One is to automatically complete all the work through program control, and the other is to manually perform each step of the operation, which can be used according to the actual situation.

[0046] It should be understood that the above specific embodiments of the present invention are only used for illustrative explanation or interpretation of the principles of the present invention, and do not constitute a limitation to the present invention.
