Description

Technical Field

[0001] The utility model relates to the field of forage processing machinery, in particular to a net bag type grass bale lifting device. Background Art

[0002] At present, due to the limitations of many reasons such as the variety of bales, bales have gradually developed from the original two-rope and three-rope bales to net bag type. The demand for picking up straw net bag bales and wheat straw net bag bales has increased year by year, and the market is in short supply.

[0003] However, the bale lifting device of the existing bale picker cannot meet the needs of picking up net bag bales. The fork of the existing bale lifting device cannot be turned over and rotates with the chain. When the net bag bale is not completely separated when it reaches the upper end of the picker, the fork scrapes the net bag and directly damages the net bag. When the existing bale lifting device lifts the net bag bale, the fork is very easy to damage the net bag and scratch the net bag, causing the bale to fall apart. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a net bag type straw bale lifting device to avoid damaging the net bag and meet the needs of picking up the net bag type straw bales.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A net bag type bale lifting device comprises a fork plate, a chain and a connecting assembly; the connecting assembly is fixedly connected to the chain; the fork plate is hinged to the connecting assembly, and during the picking process, the fork plate is inserted into the net bag of the net bag type bale; the connecting assembly comprises a first limit member and a second limit member, the first limit member and the second limit member limit the front and rear positions of the fork plate when flipping, and the first limit member also supports the fork plate.

[0007] Furthermore, the fork plate is U-shaped, and the front end is pointed.

[0008] Furthermore, the pointed end is provided with a transition rounded corner.

[0009] Furthermore, the connection assembly includes a vertical plate, a first limiter, a shaft sleeve, a rotating shaft and a second limiter, the first limiter, the shaft sleeve and the second limiter are fixed to the vertical plate, the rotating shaft and the shaft sleeve are rotatably connected, and the fork plate is fixed to the rotating shaft.

[0010] Furthermore, it also includes a transition plate, which is fixed to the vertical plate and the chain connecting plate. The transition plate forms a gap between the vertical plate and the chain to prevent the vertical plate from scratching the chain.

[0011] Compared with the prior art, the utility model has at least the following technical effects or advantages:

[0012] 1. The connection assembly of the utility model is fixedly connected to the chain, and the fork plate is hinged on the connection assembly, and the fork plate can be turned over. During the picking process, the fork plate is inserted into the net bag, and the chain is driven upward by the rotation of the motor, driving the net bag and the straw bale to move upward. When the straw bale is lifted to a certain position, the chain runs downward, and the fork plate turns downward under the action of gravity, and detaches from the straw bale in advance with the movement of the chain, thereby avoiding scratching the net bag and causing the straw bale to fall apart. The first limiter and the second limiter play the role of limiting the flipping of the fork plate, and play the role of fixing the front and rear positions, and the first limiter also plays a supporting role for the fork plate, sharing the pressure on the fork plate during the lifting of the straw bale, and also plays a lifting support role.

[0013] 2. The transition plate of the utility model is welded to the chain connecting plate, so that there is a gap of the thickness of the plate between the vertical plate and the chain, and when the chain is running, there will be no scratching of the chain.

[0014] 3. The fork plate of the utility model is in the shape of a U-shape, with a pointed front end and a transition rounded corner at the pointed end. The pointed front end is convenient for inserting the net bag bale to lift the bale; when the net bag bale is separated from the chain, the pointed end has a transition rounded corner and the top end is spherical so as not to scratch the net bag.

[0030] [Example]

[0031] like Figure 1-7 As shown, a net bag type bale lifting device comprises a fork plate 1, a chain 2 and a connecting assembly 3. The chain 2 is driven by a motor and a sprocket.

[0032] like Figure 4 As shown, the fork plate 1 is in the shape of a U, and the front ends of the two fork heads of the fork plate 1 are pointed, and the pointed ends are provided with transition fillets to form a spherical shape. The pointed front end is convenient for inserting the net bag bale to lift the bale; when the net bag bale is separated from the chain, the fork plate 1 rotates with the net bag and the pointed end is provided with a transition fillet, and the top end is spherical and will not scratch the net bag.

[0033] like Figure 5-7 As shown, the connection assembly 3 includes a vertical plate 31 , a limiting plate 32 (a first limiting member), a shaft sleeve 33 , a rotating shaft 34 , a limiting round rod 35 (a second limiting member) and a transition plate 36 .

[0034] Two sleeves 33 are welded to the two ends of the bottom of one side of the vertical plate 31. The two ends of the rotating shaft 34 are respectively installed in the two sleeves 33. The rotating shaft 34 can rotate around its own axis. Two limit plates 32 are welded to the bottom of one side of the vertical plate 31, located between the two sleeves 33. The bottom of the limit plate 32 is provided with a notch corresponding to the rotating shaft 34. The limit round rod 35 is welded to the bottom of the vertical plate 31.

[0035] The fork plate 1 is fixed to the rotating shaft 34 and can be turned around the rotating shaft 34. The limit plate 32 and the limit rod 35 can limit the turning of the fork plate 1 and fix the front and rear positions. The limit plate 32 also supports the fork plate 1, shares the pressure on the fork plate 1 during the lifting process of the straw bale, and also supports the lifting.

[0036] The transition plate 36 is a rectangular flat plate welded to the other side of the vertical plate 31. The transition plate 36 is welded to the chain connecting plate. The transition plate 36 forms a gap of the thickness of the transition plate 36 between the vertical plate 31 and the chain to prevent the vertical plate 31 from scratching the chain 2 when the chain 2 is running.

[0037] like Figure 1-3 As shown, the working principle and working process of the utility model are as follows:

[0038] During the picking process, the fork plate 1 is inserted into the net bag, and the chain 2 is driven upward by the rotation of the motor. The direction of the arrow is the movement direction of the chain 2. The fork plate 1 drives the net bag and the straw bale to move upward. When the straw bale is lifted to a certain position, the chain 2 runs downward, and the fork plate 1 flips downward under the action of gravity, and detaches from the straw bale in advance with the movement of the chain 2, thereby avoiding scratching the net bag and causing the straw bale to fall apart.

[0039] The utility model has the advantages of simple structure and strong practicability, has been put into actual production, achieved good results and meets the needs of picking up net bag type grass bales.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
