Description

Technical Field

[0001] The utility model relates to the technical field of sunshade equipment for tomato harvesters, in particular to a sunshade shed and a tomato harvester. Background Art

[0002] As the cost of manual harvesting of processed tomatoes becomes increasingly high, mechanized harvesting has become an inevitable trend in tomato harvesting. As the most important equipment in the mechanization of tomato harvesting, the tomato machine plays an increasingly important role. In the mechanized harvesting of tomatoes, the harvested tomatoes contain a large amount of impurities such as mulch, drip irrigation tape, and soil clods, which require manual cleaning of debris on the sorting platform. The tomato machine's sunshade provides shade and shelter for the pickers, providing an excellent working environment. Since the sunshade is in a relatively high working state and its width exceeds the outer width of the entire machine, it needs to be folded or disassembled for transportation when the equipment is transferred due to road conditions and national laws. Existing sunshades generally simply adjust the angle and position of the sunshade by placing the screw connection points at different positions of the support rod group holes. This adjustment method has the disadvantages of being inconvenient to operate, laborious, and unreliable. Utility Model Content

[0050] The beneficial effect of adopting the above-mentioned further technical solution is that all hinge points adopt a stepped shaft structure to ensure that a suitable torque can be achieved and prevent loosening.

[0051] 1. Composition:

[0052] The upper end of the front telescopic strut 2 is hinged to the front outer end of the awning body 1 through a step shaft, and the lower end of the front telescopic strut 2 is hinged to the front end of the frame through a step shaft; the upper end of the rear telescopic strut 3 is hinged to the rear outer end of the awning body 1 through a step shaft, and the lower end of the rear telescopic strut 3 is hinged to the rear end of the frame through a step shaft; the upper end of the front strut 4 is hinged to the front inner end and the middle inner side of the awning body 1 through a step shaft, and the lower end of the front strut 4 is fixed to the front end and the middle part of the frame respectively; the upper end of the rear strut 5 is hinged to the rear inner end of the awning body 1 through a step shaft, and the lower end of the rear strut 5 is fixed to the rear end of the frame.

[0053] The telescopic rod assembly is assembled from a telescopic rod sleeve 7, a telescopic rod body 8, a gas spring fixing bolt 9, an elastic pin 10, an auxiliary limit bolt 11, a gas spring fixing nut 12, a gas spring (including a gas spring piston cylinder 13 and a gas spring piston rod 14), an elastic cylindrical pin 15, and an auxiliary limit nut (limit nut 16). The gas spring piston cylinder 13 is fixed to the telescopic rod sleeve 7 by the gas spring fixing bolt 9 and the gas spring fixing nut 12, and the gas spring piston rod 14 is fixed to the telescopic rod body 8 by the elastic cylindrical pin 15. The length of the telescopic rod assembly is adjusted by adjusting the telescopic length of the gas spring, thereby controlling the opening angle of the awning. When the awning is opened to the maximum angle, the gas spring is adjusted to the maximum elastic extension length. At this time, the elastic pin 10 is inserted into the positioning group hole coaxial with the telescopic rod sleeve 7 and the telescopic rod body 8, which plays the role of upper limit locking; when closing the awning, the gas spring is compressed until the telescopic rod sleeve 7 contacts the auxiliary limit bolt 11. At this time, the elastic pin 10 is inserted into the positioning group hole coaxial with the telescopic rod sleeve 7 and the telescopic rod body 8, which plays the role of lower limit locking.

[0054] 2. Functional aspects:

[0055] When the awning is normally deployed, the supporting force of the gas spring supports and stabilizes the awning body, while the elastic pin 10 acts as a limit lock, ensuring reliable position control and avoiding safety hazards. When folding the awning, remove the elastic pin 10. At this time, the awning body will not slide down rapidly due to gravity due to the supporting force of the gas spring. Gently pull the outer end of the awning body 1, and the awning body 1 will rotate along the hinge axis connecting the front and rear support rods 4 and 5 to the awning body 1. When the telescopic rod sleeve 7 contacts the auxiliary limit bolt 11, insert the elastic pin 10 into the positioning hole coaxial with the telescopic rod sleeve 7 and the telescopic rod body 8 to achieve the limit lock in the folded state.

[0056] When the awning is folded and needs to be opened, the elastic pin 10 is pulled out. Under the support force of the gas spring, the outer end of the awning body 1 is gently pulled. The awning body 1 rotates along the hinge axis connecting the front and rear support rods 4 and 5 to the awning body 1. When the gas spring is extended to its maximum elastic length, the awning reaches its maximum opening angle. At this time, the elastic pin 10 is inserted into the coaxial positioning hole of the telescopic rod sleeve 7 and the telescopic rod body 8 to achieve the limit lock in the expanded state. Under the support force of the gas spring, the awning is opened conveniently, labor-savingly, and safely.

[0057] 1. The awning and its adjustment and limiting structure mainly consist of the awning body, two telescopic struts with embedded gas springs (front telescopic strut 2 and rear telescopic strut 3), three support rods (front strut 4 and rear strut 5), and two elastic pins (elastic pin 10 and elastic cylindrical pin 15).

[0058] 2. All hinge points adopt stepped bolt (stepped shaft) structure to ensure that the appropriate torque can be achieved.

[0059] 3. The nominal force values ​​of the front and rear gas springs vary with the weight of the awning and the position of the telescopic rod.

[0060] 4. The gas spring is placed in the sleeve (telescopic rod sleeve 7) and rod body (telescopic rod body 8) of the telescopic support rod and does not leak out.

[0061] 5. There are at least 5 groups of holes (positioning holes) on the telescopic support rod sleeve (telescopic rod sleeve 7) that can cooperate with the telescopic rod body 8 to match the holes of the telescopic rod body when the awning requires different opening angles, and are limited by the pin (elastic pin 10).

[0062] The awning and its adjustment and limiting structure mainly consist of the awning body 1, telescopic struts with embedded gas springs, support rods, elastic pins, etc. The awning body and each support rod are hinged through a step bolt (step shaft) to ensure that the connection torque is reached and prevent loosening.

[0063] When the awning is in the open state, the supporting force of the gas spring provides stability for the awning body (awning main body), and at the same time cooperates with the limit pin (elastic pin) to provide reliability for the limit; there are at least 5 groups of holes on the telescopic support rod sleeve (telescopic rod sleeve 7) that can cooperate with the rod body (telescopic rod body), thereby realizing the feasibility of multi-angle adjustment of the awning; when the awning is folded, the elastic force of the gas spring offsets part of the gravity, avoiding the safety hazard caused by the sudden and rapid decline of the awning. Similarly, when the awning is opened, the elastic force of the gas spring offsets part of the gravity, avoiding the difficulty in operating the awning when opening; by matching the appropriate nominal force of the gas spring with the gravity of the awning and the arrangement position of the gas spring, the appropriate opening and closing force can be obtained to achieve the purpose of convenient, labor-saving and safe operation of the awning.

[0064] As an alternative to the above solution:

[0065] 1. Directly use two gas springs to replace the telescopic rod and limit pin combination of the above-mentioned embedded gas spring;

[0066] 2. The hinge points of the awning body (awning main body) are replaced by non-metallic inserts or metal insert locking nuts instead of step shafts.

[0067] The difference between the alternative solution and the above solution is:

[0068] 1. Directly using two gas springs cannot achieve the limit of multiple opening or folding angles of the awning, and the folded state of the awning may require a separate auxiliary limit locking structure to prevent the awning from automatically opening due to vibration; in addition, directly using gas spring support may require a large nominal force, resulting in a large folding operation force and inconvenient operation.

[0069] Using a lock nut cannot guarantee the connection torque, and the nut is prone to loosening.

[0070] In addition, the utility model also provides a tomato harvester, comprising any one of the above-mentioned sunshades.

[0071] The beneficial effects of adopting the technical solution of the present utility model are as follows: when the awning is in the normal unfolded state, the supporting force of the gas spring supports and stabilizes the awning body. When the awning is folded, the elastic force of the gas spring offsets part of the gravity. Protected by the supporting force of the gas spring, the awning body will not slide down rapidly due to gravity. When the awning is in the folded state and needs to be opened, the elastic force of the gas spring offsets part of the gravity. Under the support force of the gas spring, the outer end of the awning body is gently pulled. When the gas spring is extended to the maximum elastic length, the awning reaches the maximum opening angle, avoiding the difficulty of operating the awning when opening. The gas spring is used to provide support force for the awning in the working state and stabilize the awning body; at the same time, it provides elastic force when the awning is converted from the folded state to the unfolded state, reducing manpower and safety hazards. Under the support force of the gas spring, the awning is easy to open, labor-saving, and safe.
