Description

Technical Field

[0001] The utility model relates to the technical field of agricultural transport equipment, in particular to an agricultural transport trailer. Background Art

[0002] With the development of large-scale agricultural planting, in order to improve the efficiency of sowing, fertilizing and harvesting operations, it has become a need for agricultural production to use agricultural transport trailers to supply seeds and fertilizers to the fields, as well as to transfer and transport grain in the fields. Therefore, agricultural transport trailers have been widely used. In actual use, existing agricultural transport trailers still have shortcomings: first, the functions are relatively single. Some can only transport and supply seeds or fertilizers to the sowing machines in the field, and some can only complete the transfer and transportation of harvested grain in the field, and none of them have the function of transporting and spreading organic fertilizer in the field. At the same time, due to the single function, on the one hand, in order to meet the needs of different uses, it is necessary to purchase multiple models, which increases the cost of purchasing the machine. In addition, when transporting fertilizers, the existing transport trailers have corrosion on the bottom of the car body. Severe corrosion requires repairs, which increases costs and reduces reliability and the service life of the transport vehicle. Summary of the invention

[0003] The purpose of the utility model is to provide an agricultural transport trailer with multiple functions, high reliability and reduced purchase cost in view of the above-mentioned problems.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the agricultural transport trailer of the utility model includes a chassis frame and ground wheels and a car body arranged on the chassis frame, and a conveying device arranged on the car body, the conveying device includes an elevator, a discharger, a support arm, a rotating mechanism, and an output dragon. The output dragon is arranged at the bottom of the car body in a longitudinal and horizontally rotatable manner, and the output dragon extends from the front end surface of the car body. The elevator is vertically arranged on the outside of the front end of the car body, and the lower end inlet of the elevator is connected with the front end of the output dragon. The discharger is horizontally arranged above the car body, and the discharger is connected with the upper outlet of the elevator through a rotating mechanism. The support arm is vertically arranged on the outer side wall of the car body, and the discharger is clamped on the upper end of the support arm when it is rotated to the longitudinal position. An anti-corrosion bottom plate is arranged below the output dragon, and the cross-section of the anti-corrosion bottom plate is groove-shaped and is made of engineering plastics. Along the axial direction of the output dragon, fixing seats are arranged at equal intervals above the output dragon, and the fixing seats are buckled with arch plates. The arch plate is in the shape of an isosceles folded plate in cross-section, and the front and rear end surfaces of the arch plate are aligned with the inner side surfaces of the front and rear end of the vehicle box. Flow limiting plates are respectively arranged on the left and right inclined surfaces of the arch plate, and the flow limiting plates are equal in length to the arch plate. Two of the flow limiting plates extend downward along the left and right inclined surfaces of the arch plate, and a long strip gap is provided between the lower edges of the two flow limiting plates and the two side surfaces of the vehicle box.

[0005] As a preferred solution of the utility model, an observation platform is provided on the front end face of the vehicle box, a valve is provided on the rear end of the vehicle box, the upper end of the valve is hinged to the upper beam at the rear end of the vehicle box, the lower end of the valve is connected to the lower beam at the rear end of the vehicle box by a self-locking buckle, and a lifting cylinder is provided between the vehicle box and the chassis frame.

[0006] As a preferred solution of the utility model, the rotating mechanism is a horizontally arranged meshing gear structure, which can be driven by a hydraulic motor.

[0007] As a preferred solution of the present utility model, the rotating mechanism is a horizontally arranged meshing gear structure, and can also be driven by a motor.

[0008] After adopting the above technical solution, the agricultural transport trailer provided by the utility model has the following beneficial effects:

[0009] 1. Multiple functions. The utility model is provided with a conveying device. During spring sowing, the tractor pulls the transport trailer to provide seeds or fertilizers for mechanized sowing operations. The seeds or fertilizers in the car box are transported to the elevator through the output dragon. The elevator lifts the seeds or fertilizers to the entrance of the discharger. The hydraulic motor drives the rotating mechanism or the electric motor drives the discharger to separate from the upper end of the support arm from the longitudinal position. The discharger can swing 90° from the longitudinal to the transverse direction, and swing to the required appropriate position to align with the seed box or fertilizer box of the planter to replenish seeds or fertilizers. In the autumn harvest season, the tractor pulls the transport trailer and accompanies the combine harvester to pick up grain. After the car box is full, it is transported to the high-box grain truck to unload the grain through the discharger. It can also wait at the end of the field for the combine harvester to pick up the grain and transport the grain from the field to the yard. In the autumn field fertilization season, the conveying device stops working, and the carriage is used to transport organic fertilizer to the field directly. The lifting cylinder is operated to tilt the carriage backward and lift it up. When the tilt angle is reached, the lower end of the valve at the rear end of the carriage is unlocked, and the valve opens to automatically drop the fertilizer to the field. This realizes the multiple functions of transporting seeds and fertilizers to the field, transporting grain between the fields, and spreading organic fertilizer with one machine.

[0010] 2. High reliability. The utility model has an anti-corrosion bottom plate under the output dragon. The cross section of the anti-corrosion bottom plate is groove-shaped and is made of engineering plastics. In this way, no corrosion will occur during the transportation of chemical fertilizers. Compared with the existing steel plate bottom plate, the steel plate bottom plate is prevented from corrosion, rust or even mildew, which makes replacement difficult and directly affects the working reliability of the whole machine.

[0011] 3. Reduce the cost of purchasing the machine. Since the utility model has multiple functions, users do not need to purchase multiple models to achieve different functions and uses, thus saving the cost of purchasing the machine. BRIEF DESCRIPTION OF THE DRAWINGS
