[0027] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application and does not limit the present application. In fact, it will be clear to those skilled in the art that modifications and variations may be made in the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as a part of an embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the embodiments of the present invention should belong to the scope of protection of the embodiments of the present invention.

[0028] At present, the cabbage harvesting process is widely adopted by manual harvesting or large-scale mechanical harvesting. In the manual harvesting process, the quality of cabbage harvesting varies, the labor intensity is high, the efficiency is low, and there is a shortage of labor. The purchase and maintenance costs of large-scale mechanical harvesting equipment are high, the operation is complicated, and the adaptability in small and medium-sized fields and complex terrain is poor, which greatly limits its application in small and medium-sized fields.

[0029] Based on this, the embodiment of the present application provides a clamping and pulling conveying device for automated harvesting, such as Figures 1 to 7As shown, in the clamping and conveying device 100 for automatically harvesting Chinese cabbages installed on the mobile vehicle 200, the clamping bracket 101 is installed on the mobile vehicle 200 inclined upward along the Chinese cabbage harvesting direction at a preset angle relative to the Chinese cabbage planting ground, and moves along the Chinese cabbage harvesting direction together with the mobile vehicle 200. Two clamping conveyor belts 102 are arranged in parallel on the clamping bracket 101. Each clamping conveyor belt 102 is provided with arc-shaped clamping protrusions and anti-slip patterns on its surface, effectively enhancing the clamping effect on the Chinese cabbages to be harvested. The two clamping conveyor belts 102 on the clamping bracket 101 move synchronously and in the same direction on the clamping bracket 101 driven by the driving unit 103, so that the rubber clamping protrusions arranged in a corresponding and cross-misaligned manner on the two clamping conveyor belts 102 form a clamping and pulling cavity, so as to clamp and pull up the Chinese cabbages to be harvested as the mobile vehicle 200 moves forward. Therefore, by the forward movement of the mobile vehicle 200 along the Chinese cabbage harvesting direction, it cooperates with the clamping and pulling cavity formed by the clamping protrusions arranged in a corresponding and cross-misaligned manner on the two clamping conveyor belts 102 moving synchronously and in the same direction to complete the clamping and pulling up of the Chinese cabbages to be harvested, and complete the continuous automatic harvesting of Chinese cabbages.

[0030] In a specific example, the clamping bracket 101 includes two bracket components arranged in parallel side by side in the width direction (the horizontal direction perpendicular to the Chinese cabbage harvesting direction). The two bracket components are connected by a connecting and stabilizing plate, so that the two bracket components form an integral body. Each bracket component further includes an upper mounting plate, a lower mounting plate and a plurality of rollers; the upper mounting plate and the lower mounting plate are arranged in parallel and inclined. A plurality of rollers are rotatably installed between the upper mounting plate and the lower mounting plate and are evenly distributed in parallel along its length direction. Among them, two opposite rollers in the two bracket components are driven by the driving unit 103 to transmit power through a bevel gear set and rotate synchronously and in the same direction. Furthermore, it drives the clamping conveyor belts 102 wound around the plurality of rollers to rotate synchronously and in the same direction, so that the rubber clamping protrusions arranged in a corresponding and cross-misaligned manner on the two clamping conveyor belts 102 form a clamping and pulling cavity, so as to clamp and pull up the Chinese cabbages to be harvested as the mobile vehicle 200 moves forward, realizing the automatic harvesting of Chinese cabbages.

[0031] In this embodiment, the front ends of the upper mounting plates of the two bracket components are connected and fixed by a connecting and mounting member with a U-shaped structure; specifically, the lower ends of the two side plates of the U-shaped structure connecting and mounting member are respectively fixedly connected to the upper mounting plates of the two bracket components; a stepping motor 113 for driving the two clamping conveyor belts 102 to rotate synchronously and in the same direction is installed on one of the two side plates of the U-shaped structure connecting and mounting member. The output end of the stepping motor 113 provides power output to the coaxially installed first transmission box 123 and second transmission box 133 through belt transmission.

[0032] The first transmission box 123 and the second transmission box 133 are respectively arranged on the upper mounting plates of the two bracket assemblies, and a first bevel gear set meshing with each other is arranged in the first transmission box 123, and a second bevel gear set meshing with each other is arranged in the second transmission box 133. The driving bevel gear 143 of the first bevel gear set and the driving bevel gear 143 of the second bevel gear set are installed on the same transmission shaft, and the transmission shaft is connected to the output end of the stepping motor 113 through a belt drive.

[0033] The passive bevel gear 153 of the first bevel gear group and the passive bevel gear 153 of the second bevel gear group are respectively connected to the rollers arranged relatively in the two bracket assemblies, so that under the drive of the stepper motor 113, the rollers arranged relatively in the two bracket assemblies are driven to rotate synchronously and in the same direction, thereby making the two clamping conveyor belts 102 rotate synchronously and in the same direction, so that the corresponding cross-staggered clamping protrusions on the two clamping conveyor belts 102 form a clamping and pulling cavity, and the cabbage to be harvested is clamped and pulled up as the walking vehicle 200 moves forward, thereby realizing the automated harvesting of the cabbage.

[0034] In another specific example, the front parts of the lower mounting plates of the two clamping assemblies are coaxially rotatably connected to the walking vehicle 200, and the rear parts of the lower mounting plates of the two clamping assemblies are connected through a connecting stabilizing plate, and the connecting stabilizing plate is connected to the walking vehicle 200 through an inclination adjustment unit 104. The inclination adjustment unit 104 uses a telescopic cylinder driven by hydraulic pressure, pneumatic pressure or electricity, one end of the telescopic rod is rotatably connected to the connecting stabilizing plate, and the other end is rotatably connected to the walking vehicle 200. The telescopic cylinder moves along its length direction to rotate the clamping bracket 101 around the axis of its rotatably connected to the walking vehicle 200, so as to adjust the inclination angle of the clamping bracket 101 relative to the cabbage planting ground.

[0035] The inclination installation angle of the clamping bracket 101 relative to the cabbage planting ground is 25°-35°. Therefore, by controlling the telescopic stroke of the telescopic cylinder, the inclination angle of the clamping bracket 101 relative to the cabbage planting ground can be infinitely adjusted to meet the efficient harvesting of cabbages in different growth states and the cabbage harvesting needs on different terrains and slopes.

[0036] The clamping and pulling conveying device 100 in the embodiment of the present application is low-priced, easy to operate, and highly adaptable. It can operate efficiently in small and medium-sized farmlands, significantly improve harvesting efficiency, reduce labor intensity, and meet the diverse needs of modern agriculture for cabbage harvesting equipment. The clamping and pulling conveying device 100 provided in the embodiment of the present application is installed on the walking vehicle 200 at a preset inclination angle relative to the cabbage planting ground along the cabbage harvesting direction, and at the same time, a container body 300 is arranged on the walking vehicle 200 so that the container body 300 is located at the rear end of the clamping and pulling conveying device 100, forming an automated cabbage harvesting vehicle. The walking vehicle 200 drives the clamping and pulling conveying device 100 and the container body 300 to move in the cabbage harvesting direction. At the same time, the clamping and pulling conveying device harvests the cabbage to be harvested in the forward direction of the walking vehicle 200 and transports it to the container body 300. In this way, the automated harvesting of cabbage is achieved, the stability of cabbage harvesting is effectively improved, the quality of cabbage harvesting is improved, and the labor intensity of personnel is reduced.
