Abstract

PURPOSE:To enable sure detection of clogging in a fertilizing machine, etc., by directly attaching a clogging sensor detecting the clogging of a transferred material in a transfer groove of a transfer roll through which the material is transferred from a transfer chamber. CONSTITUTION:A clogging sensor 5 is attached to a stationary transfer roll having fixed transmission shaft 38 and to a sliding transfer roll which can be slid along axial direction. The clogging sensor 5 is furnished with electrodes 39, 40. The side face forming a transfer groove 3 is connected with the outer circumference of the stationary transfer roll and the sliding transfer roll through the electrodes. When fertilizer is clogged between the electrodes 39 and 40, electric current is passed through the electrode and a lamp is lighted. The fertilizer attached to the transfer groove 3 is removed with a brush protruding into a transfer chamber 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a clogging detection device for a fertilizer, etc., and can be used for a rice transplanter, a sowing machine, etc.

Conventional technology A conventional device is a device that feeds out the material stored in a storage tank from this storage tank through a feeding groove provided in a feeding roll in a lower feeding chamber, and prevents the material from clogging in this feeding groove. This fertilization device does not include a clogging device 41 to detect clogging of the material even if the material is no longer fed out due to the occurrence of clogging.

Problems to be solved by the invention For example, the application used in a seeding machine! In the arrangement, the broadcast M
While traveling in front of the field, the stored seeds stored in the seed storage tank are fed out from the seed storage tank, and the related seeds are guided through the seed guide pipe and sown into the furrows made with the sowing and trenching machine. In addition, the fertilizer stored in the storage tank is fed out from the storage tank into the lower feeding chamber in a ridge provided on a feeding roll, and this fed fertilizer is guided by a fertilizer guide pipe and cultivated using a fertilization groove type. Fertilizer is applied into the trench, but if it rains during the sowing and fertilization process, some of the rain may flood into the storage tank, and if this happens, the fertilizer will not be delivered. was there.

Means for Solving the Problems This invention provides a feeding groove (3) provided on the rotating circumferential surface.
E′!
