Description

Technical Field

[0001] The utility model relates to the technical field of sowing equipment, in particular to a flexible tray-separating claw of a tray-feeding machine. Background Art

[0002] The existing tray feeding machine is as shown in the attached manual. Figure 7 As shown, it includes a rotating shaft 90 and a rigid supporting claw 92 fixed on the rotating shaft. The rigid supporting claw 92 includes a supporting claw seat 921 fixed to the rotating shaft and a paddle 922 fixed to the supporting claw seat by a screw. Although the relative position between the paddle and the supporting claw seat can be adjusted by loosening the screw, in the process of lifting the seedling tray 91, the supporting claw seat and the paddle are fixed. Since the rigid supporting claw flips upward and the end of the paddle moves in an arc line, in the process of lifting the seedling tray, the end of the paddle of the rigid supporting claw gets closer and closer to the side wall of the seedling tray until the end of the paddle is squeezed against the side wall of the seedling tray, thereby causing damage to the seedling tray and reducing the service life of the seedling tray. Utility Model Content

[0003] The purpose of the utility model is to provide a flexible tray support claw for a tray supply machine, which is slidably connected to the claw base through a movable claw and supported by a spring, so that the movable claw can automatically retract and retract when encountering resistance during the process of lifting the seedling tray, avoiding hard contact with the seedling tray, thereby effectively protecting the seedling tray and increasing the service life of the seedling tray.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A flexible disc-distributing claw for a disc feeding machine comprises a claw base and a movable claw slidably connected to the claw base, wherein a sharp-angled protrusion is formed on one end of the movable claw away from the claw base;

[0006] A first lug is formed at the lower end of the claw base, and a second lug is formed at the lower end of the movable claw. A screw is sleeved on the first lug, and the screw is threaded on the second lug; a compression spring is sleeved on the screw, and the compression spring is clamped between the first lug and the second lug.

[0007] The claw base is fixed on the rotating shaft of the tray supply machine for separating the trays, and the rotating shaft is provided with two claws arranged on both sides of the seedling tray; the pointed protrusion of the movable claw is tilted downward, and multiple seedling trays are stacked on the conveyor belt, and a flexible tray separation claw is provided on both sides of the seedling tray.

[0008] When the trays need to be separated, the rotating shaft rotates, and the rotating shaft drives the claw base to rotate, and the claw base drives the movable claw to flip, and the pointed protrusion of the movable claw flips upward to lift up all the seedling trays except the bottom one to a certain height. The bottom seedling tray flows out with the conveyor belt because there is no restriction from the seedling tray above; and the movable claw rotates around the rotating shaft, and the path of the movable claw is an arc line. In the process of lifting the seedling tray, the pointed protrusion may contact the side wall of the seedling tray. After contact, the pointed protrusion is subjected to the resistance of the side wall of the seedling tray, causing the movable claw to move toward the rotating shaft on the claw base, thereby preventing the pointed protrusion from hard hitting the side wall of the seedling tray, thereby preventing the seedling tray from being damaged.

[0009] The utility model is further configured as follows: a through groove is formed on the movable claw and passes through the middle of the sharp-angled protrusion, a bearing is provided in the through groove, the bearing is inserted into the shaft sleeve, the shaft sleeve is sleeved on the middle of the support shaft, and both ends of the support shaft are fixed on the movable claw.

[0010] When the supporting claw flips upward, the bearing can contact the upper flange of the seedling tray before the sharp-angled protrusion. The rotation of the bearing can prevent the supporting claw from making hard contact with the seedling tray. At the same time, the bearing is rotated under force and acts on the movable claw through the support shaft, so that the movable claw approaches the rotating shaft, thereby further avoiding the sharp-angled protrusion from colliding with the seedling tray and further protecting the seedling tray.

[0011] The utility model is further configured as follows: a locking nut is threaded onto the screw, and the locking nut is pressed against the second lug, thereby locking the screw to prevent it from freely rotating and falling off from the second lug.

[0012] The utility model is further configured as follows: the claw base is formed with an axial hole, a keyway is formed on the axial hole, a threaded through hole is formed on the bottom surface of the keyway, the axial hole is inserted into the rotating shaft, a flat key is sleeved in the keyway, the other end of the flat key is inserted into the rotating shaft, a locking screw can be screwed on the threaded through hole, the locking screw presses against the flat key to limit the flat key, thereby ensuring that the rotation of the rotating shaft can drive the claw base to rotate.

[0013] The utility model is further configured as follows: the tip of the pointed protrusion is formed with an arc portion, and when the arc portion contacts the seedling tray, the wear on the side wall and the upper flange of the seedling tray can be reduced.

[0014] The utility model is further configured as follows: the claw base is formed with a pair of parallel rectangular support bars;

[0015] A rectangular slide groove with an opening on the rear side is formed on the side wall of the movable claw, and the rectangular support bar is inserted into the corresponding rectangular slide groove. The cooperation between the rectangular slide groove and the rectangular support bar can not only provide stable support for the movable claw, but also ensure smooth sliding.

[0016] The outstanding effects of the utility model are:

[0017] Compared with the existing technology, the movable claw is slidably connected to the claw base and supported by a spring, so that the movable claw can automatically retract and retract when encountering resistance during the process of lifting the seedling tray, avoiding hard contact with the seedling tray, thereby effectively protecting the seedling tray and increasing the service life of the seedling tray.

[0030] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] The following references Figures 1 to 6 The utility model is described as follows:

[0032] A flexible tray-separating claw for a tray-feeding machine, such as Figure 1 、 Figure 2As shown, it includes a claw base 10 and a movable claw 20 slidably connected to the claw base 10, and a sharp-angled protrusion 202 is formed on one end of the movable claw 20 away from the claw base 10;

[0033] A first lug 101 is formed at the lower end of the claw base 10, and a second lug 201 is formed at the lower end of the movable claw 20. A screw 30 is sleeved on the first lug 101, and the screw 30 is screwed on the second lug 201; a compression spring 31 is sleeved on the screw 30, and the compression spring 31 is clamped between the first lug 101 and the second lug 201.

[0034] The claw base is fixed on the rotating shaft 90 of the tray supply machine for separating the trays, and the rotating shaft is provided with two respectively arranged on both sides of the seedling tray 91; the pointed protrusion of the movable claw is tilted downward, and multiple seedling trays are stacked on the conveyor belt, and a flexible tray separation claw is provided on both sides of the seedling tray.

[0035] When the trays need to be separated, the rotating shaft rotates, and the rotating shaft drives the claw base to rotate, and the claw base drives the movable claw to flip, and the pointed protrusion of the movable claw flips upward to lift up all the seedling trays except the bottom one to a certain height. The bottom seedling tray flows out with the conveyor belt because there is no restriction from the seedling tray above; and the movable claw rotates around the rotating shaft, and the path of the movable claw is an arc line. In the process of lifting the seedling tray, the pointed protrusion may contact the side wall of the seedling tray. After contact, the pointed protrusion is subjected to the resistance of the side wall of the seedling tray, causing the movable claw to move toward the rotating shaft on the claw base, thereby preventing the pointed protrusion from hard hitting the side wall of the seedling tray, thereby preventing the seedling tray from being damaged.

[0036] like Figure 3 As shown, the movable claw 20 of this embodiment is formed with a through groove 203 that passes through the middle of the pointed protrusion 202, and a bearing 21 is provided in the through groove 203. The bearing 21 is inserted into the shaft sleeve 22, and the shaft sleeve 22 is sleeved on the middle of the support shaft 23. The two ends of the support shaft 23 are fixed on the movable claw 20.

[0037] When the supporting claw flips upward, the bearing can contact the upper flange of the seedling tray before the sharp-angled protrusion. The rotation of the bearing can prevent the supporting claw from making hard contact with the seedling tray. At the same time, the bearing is rotated under force and acts on the movable claw through the support shaft, so that the movable claw approaches the rotating shaft, thereby further avoiding the sharp-angled protrusion from colliding with the seedling tray and further protecting the seedling tray.

[0038] In this embodiment, a locking nut 32 is threaded onto the screw 30 , and the locking nut 32 presses against the second lug 201 , thereby locking the screw and preventing it from freely rotating and falling off the second lug.

[0039] The claw base 10 of this embodiment is formed with an axial hole 102, and a keyway 103 is formed on the axial hole 102. A threaded through hole 104 is formed on the bottom surface of the keyway 103. The axial hole is inserted into the rotating shaft, and a flat key is sleeved in the keyway. The other end of the flat key is inserted into the rotating shaft. A locking screw can be screwed on the threaded through hole. The locking screw presses against the flat key to limit the flat key, thereby ensuring that the rotation of the rotating shaft can drive the claw base to rotate.

[0040] In this embodiment, the tip of the pointed protrusion 202 is formed with an arc portion 204. When the arc portion contacts the seedling tray, it can reduce the wear on the side wall and the upper flange of the seedling tray.

[0041] like Figure 4 、 Figure 5 As shown, the claw base 10 is formed with a pair of parallel rectangular support bars 105;

[0042] A rectangular slot 205 with an opening on the rear side is formed on the side wall of the movable claw 20, and the rectangular support bar 105 is inserted into the corresponding rectangular slot 205. The cooperation between the rectangular slot and the rectangular support bar can not only provide stable support for the movable claw, but also ensure smooth sliding.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
