Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery equipment, in particular to a tractor gantry baffle and a tractor with the same. Background Art

[0002] At present, during the assembly process of the hoods of most tractors on the market, the rear end of the hood is installed on the gantry at the rear end of the cabin through a hinge seat that matches it. After assembly, there will be a lot of hollow areas between the rear end of the hood and the upper part of the gantry due to the existence of the hinge seat. During the driving process of the tractor, heat will accumulate in the cabin. As the internal airflow flows, the hot air flow will easily blow backwards through the hollow area and directly act on the driver's body in the cab, which will bring a poor driving experience to the driver and even affect the driver's normal driving in serious cases. In addition, dust in the cabin will also enter the cab through the hollow area, adhere to the instrument panel or enter the interior.

[0003] Based on this, it is necessary to improve the problem of hot air reflow and the problem of dust adhesion. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tractor gantry baffle and a tractor with the same, which effectively overcomes the defects of the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A tractor gantry baffle comprises a baffle body, which is arranged vertically and has a connecting structure at its lower end which is assembled and fixed with the upper part of the gantry. A first avoidance notch for avoiding a hood hinge seat is provided in the middle area of ​​the lower end of the baffle body, and second avoidance notches for avoiding a hinge seat rotating shaft are respectively provided on both sides of the upper end of the baffle body.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the first avoidance gap is a rectangular gap.

[0009] Furthermore, the side edge lines of the lower end of the baffle plate body are set to be arc-shaped to match the contours of the two ends of the upper part of the gantry.

[0010] Furthermore, a plurality of third avoidance notches are provided at intervals at the upper edge of the baffle body for avoiding the protruding parts of the tractor instrument panel assembly.

[0011] Furthermore, the outer contour of the upper edge of the baffle body is in an arc shape.

[0012] Furthermore, a plurality of through holes are provided at intervals at both ends of the lower edge of the baffle body, and pre-tightening bolts threadedly connected to the upper end of the gantry are installed in the through holes, and the plurality of pre-tightening bolts together constitute the connection structure.

[0013] Furthermore, nuts are fixed at both ends of the lower edge of one side of the baffle body, and the multiple nuts together constitute the connection structure. The baffle body has an assembly hole that passes through the nut at a position corresponding to each nut, and the gantry is threadedly connected to the nuts one by one through multiple bolts passing through it.

[0014] Furthermore, the baffle plate body is a sheet metal part and is fixed to the nut by welding.

[0015] The beneficial effects of the utility model are as follows: the structural design is simple and reasonable; the design of the gantry baffle is adapted to the hollow area between the gantry and the hood, can effectively shield the hollow area, and is compatible with the assembly of the hood hinge seat, effectively improving the problem of hot air returning from the hollow area of ​​the engine compartment of the existing tractor blowing out and contacting the driver's body and affecting the posture, and also improving the phenomenon that dust easily enters the inside of the instrument panel from the hollow area.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1

[0023] like Figure 1 , 2As shown in Figures 3 and 4, the tractor gantry baffle of this embodiment includes a baffle body 1, which is vertically arranged and has a lower end provided with a connecting structure 11 assembled and fixed with the upper part of the gantry (denoted by a in the figure), a first avoidance notch 12 for avoiding the hood hinge seat is provided in the middle area of ​​the lower end of the baffle body 1, and second avoidance notches 13 for avoiding the hinge seat rotating shaft are respectively provided on both sides of the upper end of the baffle body 1.

[0024] Tractors on the market are equipped with a gantry in the cabin near the rear end cab. The rear end of the hood is generally mounted on the upper end of the gantry using a hinge seat that is compatible with it. The hinge seat generally includes a rotating shaft (denoted by b in the figure) and a hinge sleeve (denoted by c in the figure). The sleeve is passed through the middle of the rotating shaft. The hinge sleeve is connected to the upper end of the gantry through a bracket (denoted by d in the figure). Therefore, some hollow areas are formed between the upper part of the gantry and the rear end of the hood. The tractor gantry baffle of this embodiment is installed on the upper part of the gantry. Specifically, the lower edge of the baffle body 1 is overlapped on the upper front side of the gantry, and the assembly with the gantry is completed by using the connection structure 11. At the same time, the bracket of the hinge sleeve of the hinge seat at the rear end of the hood passes through the first avoidance gap 12 at the lower end of the baffle body 1, and is connected and fixed to the upper part of the gantry from the front side. The two ends of the rotating shaft of the hinge seat are bent rod sections, and pass through the second avoidance gap 13 on the corresponding side from back to front, and are connected and fixed to the two sides of the inner wall of the hood. The baffle body 1 can effectively block the hollow area between the gantry and the rear end of the hood, and its design is compatible with the assembly of the hinge seat without causing interference. The overall structural design is simple and reasonable, and can effectively block the hollow area, improve the problem of the hot air return path in the engine compartment of the existing tractor blowing out of the hollow area to contact the driver's body and affect the posture, and also improve the phenomenon that dust easily enters the inside of the instrument panel from the hollow area.

[0025] As a preferred implementation, the first avoidance gap 12 is a rectangular gap.

[0026] In the above implementation scheme, the shape design of the first avoidance gap 12 is adapted to the bracket at the lower end of the hinge sleeve. Specifically, the lower end of the hinge sleeve adopts two sheet metal parts, which are bent from the rear end of the first avoidance gap 12 and pass through the first avoidance gap 12, and then assembled on the front side of the upper part of the gantry by welding or bolting.

[0027] As a preferred embodiment, the side edge lines of the lower end of the baffle body 1 are set to be arc-shaped to match the contours of the two ends of the upper part of the gantry.

[0028] In the above implementation scheme, since the gantry is a portal-shaped frame, rounded corners are generally used for transition between the two ends of its upper horizontal section and the upper end of the vertical section. Therefore, the side edge lines of the lower end of the baffle body 1 are designed to be arc-shaped to match the rounded corner transition portion. During assembly, the lower end of the baffle body 1 is overlapped on the front side of the upper part of the gantry, and the connection structure 11 is used to realize the assembly of the two.

[0029] In this embodiment, a plurality of third avoidance notches 14 are provided at intervals at the upper edge of the baffle body 1 for avoiding the protruding parts of the tractor instrument panel assembly. Specifically, the instrument panel assembly generally has a protruding part (a product of the prior art). Therefore, in order to enable the instrument panel and the baffle body 1 to be compactly installed, a third avoidance notch 14 adapted to the protruding part is provided at the upper end of the baffle body 1 so that the two can be well assembled. The shape of the third avoidance notch 14 can be designed according to the actual shape of the protruding part of the instrument panel assembly, and will not be elaborated here.

[0030] As a preferred embodiment, the outer contour of the upper edge of the baffle body 1 is arc-shaped.

[0031] In the above-mentioned implementation scheme, since the longitudinal cross-section of the hood is generally designed to be similar to an arc shape, or at least the two ends of the upper part are arc-shaped curves, the upper end of the baffle body 1 is designed to be an arc shape that matches the inner top wall of the hood. After assembly, the gap between the baffle body 1 and the inner wall of the hood is small, and the hot air flow in the hood (that is, in the cabin) will be effectively blocked when it flows to the baffle body 1, and the phenomenon of dust passing through and adhering to the dashboard is also effectively suppressed.

[0032] In this embodiment, at least the following two assembly structures are used between the baffle plate body 1 and the gantry:

[0033] 1) If Figure 2 As shown, a plurality of through holes are provided at intervals at both ends of the lower edge of the baffle body 1, and pre-tightening bolts threadedly connected to the upper end of the gantry are installed in the through holes, and the plurality of pre-tightening bolts together constitute the connection structure 11. In this scheme, pre-tightening bolts are inserted into the through holes at the lower edge of the baffle body 1, and the pre-tightening bolts are connected and assembled with the screw holes adapted to the upper end of the gantry.

[0034] 2) If Figure 3 As shown, nuts are fixed at both ends of the lower edge of one side of the baffle body 1, and a plurality of the nuts together constitute the connection structure 11. A mounting hole penetrating with the nut is opened at a position corresponding to each nut on the baffle body 1, and the gantry is threadedly connected with the nut in a one-to-one correspondence through a plurality of bolts passing through the gantry. In this solution, nuts are assembled on one side of the lower end of the baffle body 1, and mounting holes corresponding to the holes of the nuts are opened, and bolts are passed through the corresponding position of the upper end of the gantry, and the bolts and nuts are screwed together to achieve assembly of the two.

[0035] Preferably, in solution 2), the baffle body 1 is a sheet metal part and is fixed to the nut by welding.
