Description

Technical Field

[0001] The utility model relates to the technical field of square balers, in particular to a protective cover structure of a square baler which can be opened and closed on both sides and is easy to inspect. Background Art

[0002] Square hay balers are often used in the market. Faults such as safety bolt breakage, feed transmission jamming, plunger and fork, large needle and plunger, and large needle and knotter timing errors often occur. In the original structure, the guard on the right side of the machine's forward direction is installed together with the left guard by inserting two pivot supports into the upper and lower curlings through the curling process. Only the left guard can be rotated to open and close, and the safety bolts of the reduction box can be replaced. However, the right guard cannot be rotated, and it is fixed by bolts at the middle beam and knotting mechanism of the machine body, which makes it difficult to repair the feed transmission and knotting mechanism. When the side transmission, safety bolts, knotting parts, etc. need to be repaired and replaced, the entire left and right guards need to be removed, which consumes time and delays the baling progress of the machine. To this end, a guard structure that can be opened and closed is designed to reduce the manpower and material resources spent on machine maintenance and greatly improve the work efficiency of the machine.

[0028] like Figure 1 and Figure 3 The support frame 6 is installed on the frame by bolts, and a vertical pipe 601 is vertically welded thereon. The rotating shaft 5 is vertically fixed on the long side of the right protective cover 2.

[0029] The pivot support 4 is provided with an axial hole at one end of its plate surface. There are three pivot supports 4, namely a first pivot support 401, a second pivot support 402 and a third pivot support 403 having the same structure. The bottom of the rotating shaft 5 is inserted downward into the axial hole of the first pivot support 401 and the vertical tube 601 in sequence, and the top of the rotating shaft 5 is inserted upward into the axial hole of the second pivot support 402 and the axial hole of the third pivot support 403 in sequence. The second pivot support 402 is superimposed on the bottom of the third pivot support 403 and overlapped at the axial hole. The plate surfaces of the first pivot support 401, the second pivot support 402 and the third pivot support 403, except for a section of the axial hole, are respectively fixed to the corresponding bottom curling edge of the left protective cover 1, the top curling edge of the left protective cover 1 and the middle beam 3 with bolts, so that the three pivot supports act as hinges, and the left protective cover 1 and the right protective cover 2 can be opened freely.

[0030] The left protective cover 1 and the right protective cover 2 are provided with holes at their opening and closing positions, and can be mounted on the frame through the hand ball bolt 7. The top curling edge of the right protective cover 2 is also provided with a pin hole and can be mounted on the frame through the pin shaft 8. When it is necessary to inspect and maintain the feeding transmission and knotting mechanism, the hand ball bolt can be unscrewed at any time, the cotter pin can be pulled out, and then the left and right protective covers can be rotated to open, which improves the convenience of inspection.

[0031] Preferably, combined Figure 1 and Figure 2 The left protective cover 1 has two holes vertically arranged on its short side, which can be installed on the frame by hand-ball bolts 7. The right protective cover 2 has a hole on its short side and on the top bead, which can be installed on the frame by hand-ball bolts 7. The top bead of the right protective cover 2 near the short side has a pin hole, which can be installed on the frame by hand-ball bolts 7. Figure 4 By installing the pin shaft 8, the adjusting washer 9 and the cotter pin 10 at the pin hole, the top curling edge of the right protective cover 2 close to the short side is installed on the frame.

[0032] The specific structures of the first pivot support 401, the second pivot support 402 and the third pivot support 403 are the same, and the first pivot support 401 is used as an example. Figure 7 Three holes are opened on the plate surface of the first pivot support 401 from one end to the other end, including an axial hole close to the side and the other two mounting holes 12. The mounting hole 12 of the first pivot support 401 is fixed to the bottom curling edge of the left protective cover 1 with bolts, the mounting hole 12 of the second pivot support 402 is fixed to the top curling edge of the left protective cover 1 with bolts, and the mounting hole 12 of the third pivot support 403 is fixed to the middle beam 3 with bolts.

[0033] The structure of the right protective cover 2 is matched with the structure on the right side of the machine in the forward direction, such as Figure 5 and Figure 6 The right protective cover 2 includes a trapezoidal plate 201 with short sides and a vertical plate 202 with long sides. A reinforcing rib 11 is welded on the vertical plate 202 at the position where it is combined with the trapezoidal plate 201, making the right protective cover 2 more durable. For the right protective cover 2, a horizontal plate 13 is provided on the top and bottom curling edges of the vertical plate 202. A hole is coaxially opened on the horizontal plate 13 near the long side of the vertical plate 202 for clamping with the above-mentioned cone structure, so that the rotating shaft 5 is vertically fixed on the long side of the right protective cover 2.

[0034] like Fig. 9 The rotating shaft 5 is provided with several sections, including a main rod 501 and two sleeve rods 502. The two sleeve rods 502 are respectively inserted into the two ends of the main rod 501 for fixing, and a conical structure is adopted at the joint. After the rotating shaft 5 is vertically fixed, the sleeve rod 502 at the bottom thereof is coaxially fixed with a limiting ring 13. A section of the sleeve rod 502 located at the bottom of the limiting ring 13 is inserted into the vertical pipe 601, and a section of the sleeve rod 502 located at the top of the limiting ring 13 is inserted into the shaft hole of the first pivot support 401. In order to make the right protective cover 2 rotate freely, as shown in FIG. Figure 8 As shown, the gap d between the bottom curling edge of the vertical plate 202 in the right protective cover 2 and the first pivot support 401 is set to 0.5-1 mm.

[0035] The working principle of this utility model:

[0036] The entire shield structure includes a left shield 1, a right shield 2, a middle beam 3, a pivot support 4, a rotating shaft 5 and a support frame 6, which are fixed to the frame by four handball bolts 7, a pin shaft, and bolts at the pivot support 4. During maintenance, it is only necessary to unscrew the handball bolt 7, pull out the cotter pin 10, and unfasten the pin shaft 8 to complete the opening and closing of the left and right shields. When the left and right shields can be rotated to open and close, the maintenance efficiency of machine failures is greatly improved.
