Referring to fig. 3 to 5, the positioning and clamping assembly 200 further includes a mounting plate 203, and both sides of the mounting plate 203 are fixedly connected to the chains 101 at both sides through fixing plates 214, respectively; the locating pin 202 is vertically and fixedly connected with the middle part of the top surface of the placing plate 203, the bottom surface of the placing plate 203 is fixedly connected with a guide rod 204 which is coaxial with the locating pin 202, the side wall of the lower end of the guide rod 204 is vertically and fixedly connected with a limiting pin 205, the lower part of the guide rod 204 is also slidably sleeved with a sliding sleeve 206, the side wall of the sliding sleeve 206 is provided with a vertical sliding groove 207, and the limiting pin 205 is matched and penetrates through the vertical sliding groove 207; the upper part of the guide rod 204 is sleeved with a spring 208, the upper end of the spring 208 is fixedly connected with the placing plate 203, and the lower end is fixedly connected with the upper end of the sliding sleeve 206; at least three radial through grooves 209 are uniformly distributed in the circumferential direction of the placing plate 203, preferably, the number of the radial through grooves 209 is four (as shown in fig. 4), and the outer sides of the radial through grooves 209 corresponding to the bottom surface of the placing plate 203 are respectively and fixedly connected with a folded lug 210; the clamping jaw 201 comprises clamping plates 211 which correspond to the radial through grooves 209 one by one, the clamping plates 211 are bending plates, the clamping plates 211 are inserted into the radial through grooves 209 in a matching mode, the bending angles of the clamping plates 211 are hinged to the folding lugs 210, the long arm sections of the clamping plates 211 are positioned above the placing plate 203 and used for clamping the vegetable heads, the short arm sections of the clamping plates 211 are positioned below the placing plate 203 and hinged to the upper end of a connecting rod 212, and the lower ends of the connecting rod 212 are hinged to lug seats 213 fixedly connected to the side wall of the upper end of the sliding sleeve 206; when the sliding sleeve 206 falls freely to enable the top end of the vertical sliding groove 207 to be in contact with the limiting pin 205, the clamping jaw 201 is completely closed; the position of the limit pin 205 on the guide rod 204 is set so as to ensure that the included angle alpha between the short arm section of the clamping plate 211 and the connecting rod 212 is less than 180 degrees when the clamping jaw 201 is completely closed, thereby preventing the short arm section of the clamping plate 211 and the connecting rod 212 from being in a dead point position and ensuring that the clamping jaw 201 can be smoothly opened and closed.

referring to fig. 1 to 5, the driving mechanism includes a jacking cylinder 10, a cylinder body of the jacking cylinder 10 is fixedly installed on the frame 1 and located inside the chain 101, and a push plate 11 is fixedly connected to an upper end of a piston rod of the jacking cylinder 10; when the piston rod of the jacking cylinder 10 extends out, the push plate 11 can jack up the sliding sleeve 206 above the push plate to open the corresponding clamping jaw 201, when the sliding sleeve 206 reaches the highest position, the included angle alpha between the short arm section of the clamping plate 211 and the connecting rod 212 is 90 degrees, at this time, the clamping jaw 201 is completely opened, and when the piston rod of the jacking cylinder 10 is retracted, the sliding sleeve 206 falls freely, so that the clamping jaw 201 is automatically closed.

Because the positioning needle 202 and the guide rod 204 are coaxially arranged, and the radial through grooves 209 are uniformly distributed along the circumferential direction of the placing plate 203, the closing center of the clamping jaw 201 falls on the axis of the positioning needle 202, so that the clamping jaw 201 can not only clamp and position the vegetable head, but also can realize the shaping and centering of the vegetable head, the vegetable head can be kept in a vertical state as much as possible, and the vegetable head can adapt to the vegetable head with irregular shape, inwards contracted head and skew shape.

Meanwhile, as the sizes of the vegetable heads are different, the spring 208 is arranged between the sliding sleeve 206 and the placing plate 203, when the piston rod of the jacking cylinder 10 is retracted, the sliding sleeve 206 freely falls to enable the clamping jaw 201 to clamp the vegetable heads, if the vegetable heads are large at this time, after the vegetable heads are clamped by the clamping jaw 201, the sliding sleeve 206 stops falling to be in a suspension position under the action of the spring 208, incomplete closing of the clamping jaw 201 is achieved, namely the vegetable heads are different in size, the deformation of the spring 208 is different, the spring 208 can achieve adaptive adjustment of the closing angle of the clamping jaw 201 and the tensioning force during closing according to the size of the vegetable heads, the clamping jaw 201 can clamp the vegetable heads with different sizes, and the vegetable heads cannot be clamped or broken.

In order to further improve the positioning efficiency of the vegetable head, the positioning and clamping assemblies 200 are arranged into at least two groups, the positioning and clamping assemblies 200 in each group are uniformly spaced, the positioning and clamping assemblies 200 in the same group are uniformly spaced, and the push plate 11 can simultaneously push up the sliding sleeves 206 in the same group upwards, so that the clamping jaws 201 in the same group are simultaneously opened, and the vegetable head can be more conveniently inserted onto the positioning pins 202 by workers. In the present invention, the positioning and clamping assemblies 200 are grouped into three groups.

in order to facilitate the worker to smoothly insert the vegetable into the positioning needle and avoid accidentally injuring the worker due to the overlong positioning needle, the diameter of the positioning needle 202 is designed to be 2mm ~ 4mm, and the height of the positioning needle 202 is designed to be 20mm ~ 30 mm.

The following describes in detail the procedure for positioning the mustard tuber using the device of the present invention:

1. Opening the clamping jaws: the jacking cylinder 10 at the head end drives the push plate 11 to jack up the sliding sleeve 206 upwards, the sliding sleeve 206 drives the connecting rod 212, and the connecting rod 212 drives the clamping plate 211 to turn outwards, so that the clamping jaw 201 is opened;

2. Preliminary centering: the worker inserts the dish head into the positioning pin 202 in a state that the head part is downward, the central position of the head part is ensured to be inserted into the positioning pin 202 as much as possible, and preliminary centering is realized;

3. Shaping and centering: the jacking cylinder 10 drives the push plate 11 to return, the sliding sleeve 206 rapidly and freely falls down to drive the clamping jaw 201 to close, the clamping jaw 201 can be closed in a self-adaption mode to the size of the vegetable heads under the action of the spring 208, further shaping and centering of the vegetable heads are achieved in the closing process, each vegetable head is guaranteed to be in an upright state as much as possible, and uniform positioning of the vegetable heads is achieved;

4. The chain conveying mechanism 100 conveys the vegetable heads forwards, when the vegetable heads reach the tail end, the chain 101 stops, the jacking cylinder 10 at the tail end drives the clamping jaw 201 to open again, and then the vegetable heads can be taken away for subsequent peeling operation.
