[0025] In order to clearly illustrate the technical features of the scheme, the utility model will be described in detail below through specific implementation and in combination with the drawings.

[0026] In addition, in the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0027] As Figures 1-4 shown, a picking device for a pepper machine includes a frame body 1, which can be suspended with an external traction when in use, so as to continuously pick up pepper straw during walking.

[0028] The front end picking mechanism 2, the intermediate transfer mechanism 3 and the end conveying mechanism 6 are sequentially arranged along the front end to the rear end of the frame body 1 (here, the front end refers to the forward direction of the frame body 1 during specific working walking), the conveying direction of the front end picking mechanism 2 is perpendicular to the conveying direction of the intermediate transfer mechanism 3, and the conveying direction of the front end picking mechanism 2 is the same as the conveying direction of the end conveying mechanism 6, so that the pepper straw picked up by the front end picking mechanism 2 is conveyed to the intermediate transfer mechanism 3, the intermediate transfer mechanism 3 simultaneously transfers the pepper straw to the end conveying mechanism 6, and the pepper straw is dropped onto the end conveying mechanism 6, and then conveyed to other places through the end conveying mechanism 6.

[0029] Specifically, the front-end picking mechanism 2 includes a conveyor belt 202 and multiple rows of picking teeth 201. The conveyor belt 202 has the same structure as existing conveyor belts 202 (generally including a belt body 602, a motor, and pulleys, etc., which are uniformly referred to as conveyor belt 202 in this application). The multiple rows of picking teeth 201 are evenly spaced along the circumference of the conveyor belt 202. Each row of picking teeth 201 extends beyond the surface of the conveyor belt 202. When each row of picking teeth 201 rotates to the front end of the frame 1, it forms an acute angle α with the horizontal plane, where α is between 20° and 30°. Figure 3 As shown, at this angle, the picking tooth 201 can better pick up the chili peppers on the ground and, together with the pressing roller 4, transport the chili pepper stalks to the intermediate transfer mechanism 3 and the end conveying mechanism 6.

[0030] The aforementioned pressure roller 4 is rotatably mounted at the front end of the frame 1 and located above the front picking mechanism 2. When the picking tooth 201 picks up the chili stalks, the pressure roller 4 rotates continuously, thus continuously rolling the chili stalks forward. Therefore, the picking tooth 201 continuously picks up the chili stalks and conveys them backward.

[0031] The rotation of the conveyor belt 202 and the pressure roller 4 is achieved by the power unit 5. The power unit 5 is connected to the front-end picking mechanism 2 and the pressure roller 4. The two components are driven by one power unit 5 at the same time, which can save the number of power units 5 and make the structure simpler.

[0032] Furthermore, each of the aforementioned pickup teeth 201 is fixed to the conveyor belt 202 by screws. Since the pickup teeth 201 may undergo severe deformation or breakage during continuous operation, screw connection makes it easier to disassemble and replace the pickup teeth 201.

[0033] Furthermore, the structure of the aforementioned power unit 5, which jointly drives the pressing roller 4 and the conveyor belt 202, specifically includes a first hydraulic motor 501. The first hydraulic motor 501 is mounted on the frame 1. The first hydraulic motor 501 is connected to one end of one of the pulleys of the conveyor belt 202 through a first chain drive mechanism 503. The other end of this pulley is connected to the pressing roller 4 through a second chain drive mechanism 502. The second chain drive mechanism 502 not only drives the pressing roller 4 to rotate, but also realizes the function of reversing direction. That is, the rotation direction of the conveyor belt 202 is opposite to the rotation direction of the pressing roller 4 to ensure that the picking teeth 201 cooperate with the pressing roller 4 to continuously press the chili stalks backward.

[0034] Further, the second chain transmission mechanism 502 can not only achieve the purpose of power transmission to drive the compression roller 4 to rotate, but also achieve the function of reversing, and the structure is set as follows, specifically including a first sprocket 502a connected at one end of the pulley and a second sprocket 502b rotatably arranged on the frame 1, a first chain 502c is arranged between the first sprocket 502a and the second sprocket 502b, a third sprocket 502d and a fourth sprocket 502e are further arranged on the frame 1 through a rotating shaft, one end of the compression roller 4 is connected with a fifth sprocket 502f, the third sprocket 502d is in transmission and cooperation connection with the first chain 502c, and the fourth sprocket 502e and the fifth sprocket 502f are arranged with a second chain 502g therebetween.

[0035] Further, the specific structure of the intermediate transfer mechanism 3 includes two conveyor belt assemblies 301, which are located above the terminal conveying mechanism 6 and are arranged on the left and right sides of the conveying belt 202 close to the front end picking mechanism 2, so that the two conveyor belt assemblies 301 have a material falling space 10 therebetween, and the chili straw received by the two conveyor belt assemblies 301 from the front end picking mechanism 2 is continuously conveyed and converged to the intermediate position, and finally falls into the terminal conveying mechanism 6 through the material falling space 10, and it should be understood that the chili straw close to the intermediate position of the conveying belt 202 can directly fall into the terminal conveying mechanism 6 through the material falling space 10.

[0036] Further, the specific structure of each conveyor belt assembly 301 includes two transmission wheels 301a, which are rotatably arranged on the frame 1 and are arranged at intervals on the left and right sides, and a conveyor belt 301b is wound around the two transmission wheels 301a, and the rotating directions of the conveyor belts 301b of the two conveyor belt assemblies 301 are opposite, and one of the two transmission wheels 301a is connected with a second hydraulic motor 301c on the frame 1, and the second hydraulic motor 301c drives the conveyor belt 301b to rotate.

[0037] Further, the terminal conveying mechanism 6 includes two conveying wheels 601 rotatably arranged on the frame 1, and a belt body 602 is wound between the two conveying wheels 601, and one of the two conveying wheels 601 is connected with a third hydraulic motor arranged on the frame 1 (not shown due to the angle of view).

[0038] Further, in order to adjust the height and angle of the picking teeth 201, the application also provides a height limiting roller 7, which is hingedly connected to the frame 1 through a connecting frame 8, and a telescopic cylinder 9 is hingedly connected between one end of the connecting frame 8 close to the height limiting roller 7 and the frame 1, and the telescopic cylinder 9 drives the height limiting roller 7 and the connecting frame 8 to rotate around the hinge, so as to change the height of the height limiting roller 7.

[0039] Further, in order to reduce the rigid impact that the rigid pick-up tooth 201 may generate when picking up the pepper straw, the pick-up tooth 201 is made of nylon tooth, which reduces the rigid impact by deforming itself, thereby reducing the deformation and breakage of the pick-up tooth 201.

[0040] The above detailed description cannot be regarded as a limitation on the protection scope of the present application, and any alternative improvement or transformation made by the skilled in the art to the embodiments of the present application falls within the protection scope of the present application.

[0041] The unexplained parts of the present application are the common knowledge of the skilled in the art.
